Tsunade

is the who hails from the Senju clan of Konohagakure and is also a descendant of the Uzumaki clan through her grandmother Mito. She succeeded the position after the death of her teacher, Hiruzen Sarutobi. She, along with Orochimaru and Jiraiya, are recognised as "The Legendary Sannin of Konoha". She is also celebrated as the greatest medical-nin of all time and is also credited with creating the official system of the medical ninja.

Background
Tsunade is the granddaughter of the First Hokage, Hashirama Senju and Mito Uzumaki, also the grandniece of the Second Hokage, Tobirama Senju, leading others to call her. She, along with Jiraiya and Orochimaru are also former students of the Third Hokage. Like Team Kakashi, Tsunade and her teammates were given the bell test, which Jiraiya failed and was subsequently tied to a log. Tsunade taunted him before leaving.

At some point, when she caught Jiraiya peeping on her while she was in the hot springs, she proceeded to break both of his arms, six of his ribs and ruptured several internal organs as a punishment for being a pervert. Ever since then, Jiraiya has been very careful to suppress his perverted ways around Tsunade. Jiraiya mentions that this is one of the two times he has ever been close to death.

During the Second Shinobi World War, Tsunade and her former team-mates fought Hanzō, who gave them the title of Konoha's as a reward for surviving their battle. On their way back to Konoha, they encountered the Ame Orphans, whom Jiraiya chose to train. Throughout the war, she would become famous for frequently counteracting Chiyo's poisoning attempts, earning contempt from Chiyo because of it. Furthermore, according to Jiraiya, Tsunade, with her unrivaled skills as a warrior and medical prowess, was the reason Konoha won the war.

On her younger brother's twelfth birthday, Tsunade gave him their grandfather's crystal necklace in the hopes that it would help him achieve his dream of becoming Hokage. The next day, he died as a casualty of the war, which returned the necklace to Tsunade's possession. This event resolved Tsunade to advocate for the inclusion of medical-nin to be incorporated into teams that were on the battlefield. However the Third regretfully told her that because they were in a time of war, they did not have the resources or the time to train such ninja.

While Tsunade became discouraged, a man named Dan Katō spoke up to second her request also believing strongly that they should focus on finding ways to save their comrades' lives on the battlefield. Intrigued by Dan, Tsunade grew close to him and in sharing similar ideals, they fell in love with each other. As a sign of her affection, and in the hopes that this time it would help make his dreams come true, Tsunade gave him the necklace as well. Dan died a bloody death during the course of the war, once again returning the necklace to her possession. Dan's death caused her to develop hæmophobia, which made her unfit to take part in any more battles. Dan's death also led people to believe that the necklace was cursed; causing death to anyone who wears it except Tsunade.

With the deaths of the two she loved the most, Tsunade came to lose faith in the title of Hokage, believing that only a fool would want to take the position. With these changes of ideals, Tsunade left Konoha with Dan's niece, Shizune, taking her on as her apprentice who became one of the few people Tsunade trusts with absolute certainty. Tsunade also came to own a pet pig, Tonton which she leaves mostly to Shizune's care.

Personality
When she was first introduced, Tsunade was cynical of anyone with dreams, especially those who want to become Hokage. After meeting Naruto, she realises that this cynicism is insulting to the memories of both Dan and Nawaki. After seeing Naruto's conviction to become Hokage and proving her wrong in his ability to learn the Rasengan, she has a change of heart. Despite her still blunt attitude towards Naruto, she has come to care for him deeply and puts her faith in him for the future, even agreeing to take on the mantle of Hokage herself, carrying on the dreams of Dan and Nawaki. As Hokage, Tsunade has shown the same level of loyalty to the village that previous Hokage held; during the invasion of Pain, she released all of her chakra in order to save the lives of thousands of people within Konoha, at great personal risk. Tsunade also has a great deal of faith in the next generation, and sees the potential that Naruto and the rest of the Konoha 11 hold.

Tsunade typically projects a tough demeanour, even when facing great personal difficulty. She readily criticises others for their faults, such as Naruto's immaturity or Jiraiya's perversion, though her habits are rarely any better. Another trait of Tsunade is her monsterous, quick temper and many fear her because of this, such as Shizune, Jiraiya, and Sakura. Beneath this tough exterior, Tsunade truly loves her village and its people and will at times show sympathy for others, consoling Shikamaru that, while he failed his mission to return Sasuke to Konoha, all of his team-mates survived. This is also shown when she worked hard in order to help heal Rock Lee, so that he might continue to be a ninja. In life-threatening or important situations that involve putting someone she cares for in danger, she tends to get angry with people who disagree with her plan, such as the restrictions the Konoha Elders placed on Naruto, or the argument on whether Naruto and Killer B should participate in the Fourth Shinobi World War, even calling Gaara a "child" when he disagreed with her. As with all Hokage before her, Tsunade deeply believes in the Will of Fire.

Tsunade also has a firm belief that Naruto, and all jinchūriki, are not tools of war and are their own people. She has always voiced that Naruto is a great ninja and should be used by the village as any other ninja would be. This value is so strong in Tsunade that she yelled at the other Kage for not allowing Naruto and Killer B to fight in the Fourth Great Shinobi War. Although she eventually agrees to keep the jinchūriki away from the battles, she is outraged when A decides to kill Naruto to prevent him entering the war. Tsunade then turns on A, saying that they need to use the jinchūriki in the war if they are going to win. This shows her great faith in Naruto to end the war, as she was even willing to challenge the Raikage in order to let Naruto and B pass.

Tsunade is also a compulsive gambler, who has the unfortunate disadvantage of having terrible luck. As a result, she has been elevated to a comical status as because of the gross profits others have made off of her misfortune and gambling addiction. In the rare instances that Tsunade hits a winning streak, she believes it to be a bad omen, and bad things do tend to happen to her or her comrades afterwards. The symbol on the back of her coat,, means "gamble", or "wager", as gambling is one of her favourite pastimes.

Despite Tsunade shunning all of Jiraiya's romantic advances over the years, as she was still in love with Dan even after his death, she still cared very much for him as one of her oldest friends. While he was in Amegakure investigating Pain, she bets that he will die so that her terrible luck will ensure he survives. When she finds out he has died, she thinks back on their time together and mourns privately for the loss of her dear friend.

Appearance
Tsunade is a fairly tall, light-skinned woman with light golden-amber eyes and straight blonde hair. Her hair is waist-length with shoulder-length bangs framing both sides of her face. As a child, she had it tied in a high ponytail. As an adult, it is usually tied into two loose ponytails. Some time after leaving the village, she obtained a violet rhombus mark on her forehead similar to her grandmother's, which she uses as a chakra gathering point known as the Yin Seal. It will temporarily disappear when unleashing the conserved chakra and reappear after she has accumulated enough chakra.

While only in her early fifties, her form is a frail and wrinkled old appearance, more so than her age would suggest. However, she maintains the appearance of her younger self through a unique and constant Transformation Technique. In her youth, the appearance she normally takes, she had a slender yet noticeably curvaceous frame. Despite being known as flat-chested in her childhood, she now has a rather large bust; 106 centimetres in circumference, according to Jiraiya. Her beauty has been pointed out several times and she's been called the most beautiful kunoichi in the world by several characters.

She often wears a grass-green robe with the kanji for written in black on the back, inside a red circle. Underneath she wears a grey, kimono-style blouse with no sleeves, held closed by a broad, dark bluish-grey obi that matches her pants. Her blouse is closed quite low, revealing her sizeable cleavage. She wears open-toed sandals with high heels and red polish on both her fingernails and toenails. She also wears a soft pink lipstick. She also used to wear the First Hokage's Necklace in clear view on her chest, before giving it to Naruto. When she releases the Yin Seal, the diamond mark on her forehead opens out into a seal that usually extends to her jaws. When using the Strength of a Hundred Technique, the markings extend themselves around her entire body.

Abilities
As one of the Legendary Sannin and the Fifth Hokage, Tsunade is undoubtedly one of the most powerful ninja that Konoha has ever produced. She is a remarkable combatant and medical-nin and is also hailed as the world's strongest kunoichi, which has lead to many younger kunoichi to look up to her. Jiraiya commented that no one could stand equal to her in terms of combat and medical prowess. Descending from the Uzumaki and Senju clans, she also possesses an extraordinary long potential lifespan as well as strong life force.

Taijutsu
Tsunade's trademark ability is her incredible raw strength with which she is able to perform such feats as launching her targets several metres with a mere finger flick or create fissures with a single finger jab at the ground. An opponent struck by her attacks could suffer damage ranging from broken bones, ruptured organs, or even death, as Jiraiya learned for his perverted actions in his youth. While a medical-nin normally tries to avoid direct battle, Tsunade’s close-range combat skills have been considered unsurpassed, which she uses mainly to intimidate her opponents from approaching her in order to carry out her primary duties as a medical-nin. When entering battle directly, she is a force to be reckoned with as seen when she easily shattered Madara Uchiha Susanoo's ribcage and sword, and later a complete version of the Susanoo with single punches. She was also able to obliterate Madara's body with a single attack, forcing him to use the Wood Clone Technique to escape being sealed.

As a field medical-nin, Tsunade is highly skilled in the art of evasion. In battle, she has shown great ingenuity, able to quickly pick up on her opponent's fighting style and battle pattern to better avoid damage and plan her attacks around that. These traits are to keep herself alive in battle so she may heal her team-mates; things she drilled into Sakura while training her. While not her most prominent trait, she is quite fast and equally fierce in battle, having displayed high levels of quickness to the point that her opponents find her an overwhelming adversary. She was able to incapacitate Shizune with a quick strike before she could react, use the Body Pathway Derangement technique on Kabuto when he thought she was incapacitated, block Orochimaru from attacking an unconscious Naruto even though she was severely wounded, and even intercept Manda mid-bite while lifting Gamabunta's sword. Before Mei Terumi or any of the other Kages could react, Tsunade intercepted all five of Madara's Dragon Flame Bullets and bat them all away.

She also has immense vitality and stamina, stemming from her incredible inherited life force. Additionally, she has shown remarkable durability; she was still able to move after having her muscles torn, something Kabuto himself found impressive and praise-worthy. She was also able to survive the life-risking Heavenly Transfer Technique, receiving only minor injuries in the process. She could also survive a point-blank Yasaka Magatama from Madara with zero damage. Furthermore, her endurance was great enough to survive the normally fatal injuries of being stabbed straight through the shoulder, abdomen, and even chest to still land a powerful attack on Orochimaru. She was also to continue fighting with extreme force against Madara's Susanoo army despite being impaled through her abdomen with two Susanoo blades.

Intelligence
While normally appearing carefree or short-tempered, Tsunade is a capable leader. A keen thinker, Tsunade has repeatedly been highly observant and analytical, allowing her to see through most deceptions and is rarely caught off-guard. Most commonly, Tsunade will choose the best ninja available to construct a team after looking over the assigned mission. In the anime, she was able to analyse and replicate the basic mechanics of Kabuto’s regeneration technique to aid in bettering the chances of Rock Lee's life-risking surgery being a success.

Her intelligence is most renowned as the best in the world for her expertise in all areas of medicine. She has been credited with creating the official Medical-nin system and the laws that govern them. She can immediately determine what kind of injuries or illness (physical or mental) a person has from a single glance. In addition to this, Tsunade seems to have a vast knowledge of poisons and herbal medicine, as noted by Chiyo who stated that during the Second Great Shinobi War, Tsunade was the only one capable of countering all her poisons perfectly. She also has remarkable knowledge of the human psyche, as she was able to effortlessly undo the damage to Kakashi and Sasuke's minds inflicted by Itachi's Tsukuyomi in a matter of seconds. Tsunade has also proven to be a very capable teacher, having single-handedly trained Sakura and Shizune and passed on much of her knowledge make them become two of Konoha's best medical-nin and field support.

Her mental stability is also  noteworthy as she overcame her paralysing fear of blood through willpower alone, something every eyewitness found miraculous.

Chakra Reserves and Control
Tsunade has shown to have great supplies of chakra. She has able to simultaneously heal a large number of people with the help of Katsuyu over long periods of time without becoming fatigued.

When needed, Tsunade can also release a large amount of stored chakra using Yin Seal. Upon its release, Tsunade can either use the stored chakra to facilitate the activation of one of her techniques such as the Creation Rebirth, which makes her virtually immortal in battle or simultaneously heal and protect the entire citizens of Konoha from a very powerful attack such as Pain's Shinra Tensei. She is also able to transfer chakra to others as seen when gave Ōnoki some of her chakra in order to facilitate his large-scale Dust Release: Detachment of the Primitive World Technique and still manages to maintain the activation of her Strength of a Hundred Technique.

Even more impressive than her reserves is Tsunade's control. Since a young age, Tsunade excelled in all forms of chakra manipulation; even able to maintain multiple techniques at once. Her innate talent for it allows her to gather her chakra from any part of her body with such precision and perform any technique to their maximum potential without any wasted chakra or timing. Her signature ability with chakra control is to instinctively amplify her already legendary strength with chakra control to monstrous levels, allowing her to perform feats like causing gigantic craters with a simple punch or kick to the ground, launch Gamabunta's tantō into the air and then guide it down right into Manda's mouth, and destroy Madara Uchiha's Susanoo's ribcage and its sword with relative ease. This is done by building up and releasing her chakra with precise timing upon impact, making it effortless for her to decimate any target.

Transformation Technique
Even though she is in her early fifties, Tsunade's Transformation Technique makes her appear as if she were still in her twenties (which Naruto calls "living a lie"). She readily alters what age she appears in order to avoid her gambling debts. Tsunade's transformation is somewhat different from a normal transformation, as it seems to be permanent, not getting dispelled when she is slashed or injured, and she apparently does not need to exert any effort to stay transformed. She is able to maintain her transformation even while asleep. The transformation dispels when she runs out of chakra, reverting her to her natural appearance.

Medical Ninjutsu
Much of Tsunade's fame comes from her being able to perform any procedure flawlessly to cure and heal injuries that others would consider impossible or a lost cause. She can do so through the usage of no more than chakra or basic tools. She healed the psychological damage caused by Tsukuyomi, the damage done to Rock Lee's spine, and counteracted the effects of the Three Coloured Pills on Chōji, something Chōza stated would have been impossible if she weren't there. Tsunade has also been noted to be capable of making powerful sleeping potions that are also colourless; so much that she is the only one in the world who could spike a drink without a ninja knowing it was drugged.

With her remarkable knowledge of the human body and converting her chakra into electricity, Tsunade is capable of sending electric waves into the opponent's nervous system by striking the back of the neck. This then scrambles the electric signals within them and disrupts the way their body moves, such as attempting to move the right hand would cause the left leg to move instead, and so on. It is unknown if this is Lightning Release. In a similar manner, Tsunade has also shown the ability to use medical ninjutsu adversely and use it to harm, even kill, instead of heal. She can use a single chakra-infused strike to effortlessly cause internal damage or incapacitate a target as she did the latter to Shizune when she tried to stop Tsunade from meeting with Orochimaru. Tsunade is also able to create a Chakra Scalpel both for surgery and to inflict internal lacerations and even attack the internal organs.

The most extreme example of her medical prowess is her Creation Rebirth, a technique that makes use of the massive amounts of chakra available after using Yin Seal: Release to continuously create new cells in her body, healing any wound and even growing back missing organs. It gives her a form of "immortality" in battle that even Orochimaru expressed envy for. However, because of the rapid cell division, the technique shortens her life. Because of the risk associated with the technique, Tsunade only uses Creation Rebirth in extremely desperate situations. This technique is considered as the absolute pinnacle of medical ninjutsu, and Tsunade developed it under the resolution of protecting those dear to her. She also created the Strength of a Hundred Technique, an extension of the Creation Rebirth which causes the seal to extend all the way down her body. While this technique is active, any wounds Tsunade receives will heal instantaneously, without the need to make hand seals or even a conscious effort.

Summoning Technique
Tsunade can summon slugs of varying sizes, although she has only ever been seen summoning Katsuyu. The slugs' primary abilities seem to revolve around spitting acid and splitting into smaller slugs. Tsunade apparently has a mental connection with Katsuyu, as she was able to get reports and send out messages through Katsuyu during the invasion of Pain. Tsunade can transfer her chakra to a large number of slugs over long distances. By having the slugs spread out and attach themselves to wounded individuals, Tsunade is then capable of healing multiple injuries at different locations simultaneously. This technique proved particularly helpful during the Invasion of Pain which helped Tsunade preserve the life of the majority of the village even after a devastating attack by the enemy forces.

Other Skills
In the anime, Tsunade demonstrated noticeable skill in a variety of other areas. When dealing with the Legendary Stupid Brothers, her skill in genjutsu was great enough to bind the immensely strong duo at once. She was also able to use Space–Time Ninjutsu to send one of Katsuyu's divisions to Team Three's location despite the great distance.

Tsunade is also well-versed in fūinjutsu, capable of developing an S-rank seal that continuously stores up chakra for various reasons including using the high-level techniques such as the Creation Rebirth technique which she also created. In the anime, she designed the Four-Corner Sealing Barrier which can be used to seal a tailed beast from scratch.

Search for Tsunade Arc
After his failed invasion of Konoha, Orochimaru sought out Tsunade. Upon finding her, he asked her for a favour, though before he could specify what this favour was, she declined, having already noticed his wounded arms. Trying again, Orochimaru asked her to heal his arms. Kabuto then complemented Tsunade saying that she's the only one in the world who can cure Orochimaru or kill him. Tsunade noticed that Orochimaru's injury is caused by a powerful seal and when she asked him he replied explaining that the injury was a result of his carelessness when killing the Third Hokage. Shocked by this revelation, Tsunade prepared to kill Orochimaru, though he once again intervened by offering in exchange for her help, to reincarnate her lover Dan and her little brother Nawaki. Seeing that she was tempted by this offer, Orochimaru left her a week to consider his proposal.

Soon afterwards, Tsunade was approached by Jiraiya, who wanted her to become the next Hokage. After turning down the offer and ridiculing it, Naruto challenged Tsunade to a fight, enraged that someone could disrespect the title of Hokage in such a manner. Tsunade accepted, and easily won, though not before witnessing Naruto's attempt at using the Rasengan. Intrigued, Tsunade made a bet with Naruto to master the technique in a week; if he won, he would get the First Hokage's necklace, and if Naruto did not master the Rasengan within a week, Tsunade would get all the money he was carrying. Naruto accepted the bet, and resumed his training. As the week progressed, Tsunade kept a careful eye on Naruto's progress, and all the while contemplated Orochimaru's offer. When the week was up, and Naruto appeared to have failed in mastering the technique, Tsunade went to meet Orochimaru, first drugging Jiraiya to make sure he didn't interfere.

Upon meeting with Orochimaru, Tsunade asked that he will not destroy Konoha when his arms were healed. Orochimaru agreed, and Tsunade prepared to heal him, though was interrupted by Orochimaru's assistant, Kabuto Yakushi. Kabuto, being a medical-nin himself, was able to notice the killing intent of Tsunade's healing technique, and as such, knew that she really intended to kill Orochimaru. Her motives known, Tsunade revealed that she knew Orochimaru had lied when saying he'd leave Konoha alone, and that she couldn't bring herself to allow it, due to Nawaki and Dan having loved Konoha until the end of their days. While she had tried to forget this fact over the years, Naruto's determination and desire to be Hokage reminded her of their dreams, and she had decided to do whatever was necessary to protect those dreams.

With that, Tsunade attacked Orochimaru, though Kabuto fought her in his place. As the two traded blows, Kabuto began to realise that he was completely outmatched, and decided to use her fear of blood to his advantage, slitting his wrists to paralyse her. As Kabuto began to beat on Tsunade, Shizune and Naruto came to her rescue. While both were easily defeated, Naruto was able to overcome his injuries and continued to protect Tsunade. Although Tsunade told him to run, Naruto refused, and managed to hit Kabuto with a perfected Rasengan in his effort to protect her, defeating Kabuto. As Naruto collapsed, and was left near death due to Kabuto's last attack, Tsunade rushed to his aid and attempted to heal him, not willing to allow him to die. Her efforts were successful, and Naruto claimed the amulet he had now won before losing consciousness. Putting the necklace around his neck, Tsunade asked once more for its wearer to become Hokage.

Orochimaru, worrying about what kind of threat Naruto might become when he got older, tried to kill him, though Tsunade blocked that attack, using herself as a human shield. Orochimaru inquired as to why she was protecting Naruto, to which she replied that Naruto would someday be Hokage, and that she would not allow him to die before that happened. With that, Tsunade accepted the title of Fifth Hokage that she had been offered, and overcame her fear of blood, her first action being to eliminate Orochimaru. Joining forces with the still drugged Jiraiya, the two attacked Orochimaru. After a battle of summons, Tsunade dealt the finishing blow to Orochimaru. Defeated, Orochimaru escaped, vowing to destroy Konoha once he'd healed himself. Once Naruto recovered, the group returned to Konoha, Tsunade ready to take the role Dan and Nawaki so dearly desired, and secretly believing that Naruto would someday become a great Hokage. Also, like with Nawaki and Dan before Naruto, Tsunade gives him a kiss on the forehead to show her faith in him.

Sasuke Retrieval Arc
Soon after arriving in Konoha to take her place as Hokage, Tsunade healed the mental injuries inflicted by Itachi Uchiha's Tsukuyomi on Kakashi Hatake and Sasuke Uchiha. She also gave a grim prognosis on Rock Lee's condition. She stated that the only procedure that could allow him to return to duty as a ninja was one that she alone was capable of performing, and it only had a fifty percent chance of success; if it didn't succeed, then it would prove to be fatal for Lee.

Not liking the odds of such a dangerous procedure, Tsunade advised Lee that it was best that he retire as a ninja and find another profession. In the anime, while Lee is struggling to decide what he should do, Tsunade looks into ways to improve his chance of survival. Thinking back to how she had seen Kabuto withstand Naruto's Rasengan, Tsunade used Kabuto's technique as an inspiration to expand on the life-threatening operation and improved Lee's chances of survival from fifty percent to fifty-eight percent. Lee finally agreed to undergo the procedure and survives.

When Sasuke defected from the village so that he could go to Orochimaru, Tsunade was forced to send out a group of genin to try and stop and retrieve him, due to lack of manpower. She also used Konoha's reacquired alliance with Sunagakure to call in a favour for reinforcements, hoping to give the retrieval team some back-up. Despite her efforts, the group ultimately failed, and Tsunade helped in healing their fatal injuries, bringing them back to full health. She was particularly instrumental in the healing of Chōji, mixing the antidote to the side effects of the Three Coloured Pills that she got from the medical encyclopaedia kept by the Naras; a fact Chōza gratefully stated. In the aftermath of Sasuke's betrayal, Sakura Haruno asked to become Tsunade's apprentice, which Tsunade gladly accepted.

Pre-Shippūden Filler Arcs
Tsunade appeared in numerous filler arcs, though she typically did nothing more than sending others out on missions, occasionally trying new ways of deciding who would go on a specific mission. Her goal during the filler arcs was to keep Naruto busy until Jiraiya came back, to prevent him from going after Sasuke himself. When the Legendary Stupid Brothers escape from prison, she convinces them to surrender with a quick display of genjutsu and her strength. In another filler, she summoned Katsuyu to deal with some impersonators of Rock Lee and Might Guy, who had entered the village.

Part II
During the next few years while Jiraiya and Naruto were off training, Tsunade continued her duties as Hokage and her tutelage of Sakura as a field medical-nin. Also during this time, the Hokage Monument was altered to include Tsunade's face in chronological order.

Kazekage Rescue Arc
While taking care of reports for genin missions, Tsunade learned that Jiraiya and Naruto returned. Tsunade then decided to test Naruto's, as well as the now chūnin Sakura, growth as ninjas by pitting them against their former jōnin-sensei Kakashi. After the two succeeding in their challenge and received praise from Kakashi, Tsunade officially made them a unit under their old name "Team Kakashi".

Later while deciding on Team Kakashi’s first mission, Tsunade received word from Sunagakure that the Akatsuki had abducted Gaara, now the Fifth Kazekage. Out of respect for the Konoha-Suna alliance, Tsunade sent Team Kakashi to assist. A few days later, Tsunade had a bad premonition when she discovered she won a major sweepstakes. Acting on this she sent Team Guy as backup on the mission.

Sasuke and Sai Arc
After Team Kakashi and Team Guy returned from rescuing Gaara, Tsunade was informed that the fallen Akatsuki member Sasori had intended to meet an agent of his working within Orochimaru’s ranks. Seeing the chance to get intelligence on Orochimaru, Tsunade decided to have Team Kakashi capture this spy. Unfortunately, the elders were against letting Naruto go out on dangerous missions as the Akatsuki sought to capture him. Tsunade sternly voiced her belief in Naruto. The elders ultimately yielded under the condition that Tsunade added one of the men of Danzō Shimura, a fierce rival of the Third Hokage and leader of the ANBU Root division, to Team Kakashi. With Kakashi currently hospitalised, Tsunade also added an ANBU agent codenamed "Yamato", mainly for his ability to utilise the Wood Release and its ability to suppress the tailed beasts, should Naruto get out of control. She also warned Yamato to keep an eye on Danzō's addition to the team, Sai.

After Team Yamato returned, having failed their mission but gained new information on Sasuke, Tsunade surmised that Sasuke’s immense growth may have come from the assistance of Orochimaru’s use of kinjutsu and Kabuto’s medical ninjutsu. Tsunade was also troubled to learn that Danzō, in his self-righteous ideals, was willing to give the enemy top-secret information in an effort to complete the mission as Sai was instructed to give Orochimaru ANBU data should they meet.

Twelve Guardian Ninja Arc
In the anime, word reached Konoha that several villages on the Fire Country’s borders were being attacked. Tsunade sent several teams to investigate. She also sent Team Yamato to investigate several tombs near the Fire Temple being disturbed. When Team Yamato returned, they informed Tsunade that the tombrobbers were apparently after corpses of four former members of the Twelve Guardian Ninja. Team Yamato also brought an unofficial new member to the team from the Fire Temple to replace an injured Sai, a young monk named Sora. Tsunade also received a message explaining Sora’s troubled past and unusual powers that he is not able to control that lead to great damage of the Fire Temple.

Later, Tsunade had the ANBU apprehend Danzō due to his recent and possibly treacherous actions and ninja from the Amegakure with Danzō. Before she could interrogate the man, the elders arrived. They revealed that the Rain ninja was a double-agent working for them. The elders explained the same tombrobbers Team Yamato encountered may also be after Sora. The elders and Danzō came to the conclusion they should confine or eliminate him. Before Tsunade could voice her refusal, Sora was found spying on them. Convinced that Tsunade wanted to eliminate him, Sora became furious at her. Sora then asked Asuma if it was true that Asuma killed his father Kazuma. When Asuma sadly admitted it, Sora’s rage unleashed his hidden powers and was able to escape.

Later while Tsunade was deciding what to do about Sora, the village had a complete power-outage, thanks to the tombrobbers. They arrived in the village and surrounded it in a giant barrier. They voiced their distain for Konoha as they viewed as an imbalance to the Fire Country’s power and sought to destroy the village. As they overwhelmed Konoha’s forces with a zombie resurrection technique due to most of the ninjas being outside the village, Tsunade discussed the situation with Shikamaru. It was determined through Asuma that the tombrobbers intended to destroy the village with the deadly Limelight technique through the four resurrected guardians.

After the tombrobbers were defeated and Sora was purged of his powers, Tsunade forgave Sora for his mistakes and was allowed to leave the village in peace.

Hidan and Kakuzu Arc
Later, when two Akatsuki members entered the Land of Fire - namely Hidan and Kakuzu - Tsunade mobilised the Nijū Shōtai to look for and if possible, capture the Akatsuki duo. While capture never came to be possible, the Akatsuki members were both defeated. Tsunade later performed an autopsy on Kakuzu, and found Naruto's newest technique, Wind Release: Rasenshuriken to be too dangerous for use, based on the damage done to Kakuzu's body and Naruto's arm. She explained that the attack had struck at a cellular level, causing extensive damage to the both of them, and regretfully told Kakashi and Yamato not to allow Naruto to use the technique again.

Three-Tails Arc
In the anime, after finishing her autopsy on Kakuzu, Tsunade received a report from a deceased ANBU captain about Orochimaru and Sasuke's whereabouts. She called for Kakashi, and put him in charge of Team 8 to investigate. Because the mission involved a chance of finding Sasuke, Tsunade tried to keep Naruto from finding out about it. He found out anyway, so Tsunade didn't hesitate to send him as back-up.

Later, Tsunade received news that Team Kakashi had encountered the Three-Tails. Deciding that they needed to capture the beast quickly, as to not let it fall into enemy hands, Tsunade ordered Tenten, Rock Lee, and Ino Yamanaka to aid Team Kakashi in sealing the beast. Before sending them out, Tsunade made a large and special scroll to aid the team in sealing the beast. She also decided to summon and send out Katsuyu for further assistance. When the forces they sent continued to have problems with the sealing, Tsunade called them back to Konoha, and sent some ANBU to replace them. After she heard about the ANBU losing contact with Konoha, and the disappearance of the Three-Tails, Tsunade suspected that Akatsuki were somehow involved.

Itachi Pursuit Arc
After assigning Team Kakashi and Team Kurenai on a mission to find Itachi Uchiha in the hopes that it would lead them to Sasuke. Jiraiya later comes to inform her that he had found the location of the leader of Akatsuki. As both Shizune and Tsunade in shock demand that he tells them where he is so that they can immediately begin formulating a surprise attack. Jiraiya tells them both to not be so hasty and invites Tsunade for drinks, which she declines at first but ultimately ends up agreeing to it. While in Shushuya, Jiraiya reveals the details of the Akatsuki's leader and that he was in Amegakure and the difficulty of getting into the village. As Jiraiya declares that he would infiltrate the village on his own, Tsunade objects but Jiraiya reminds her that he is one of the Legendary Sannin and what that meant. After the two reminisce a bit, Tsunade tells Jiraiya to come back alive and if he needed help to send a toad and she'd come in person to back him up. On departing, Jiraiya tells her to remain cautious of Root.

Tsuchigumo Kinjutsu Arc
In the anime, word reaches Konoha that the Tsuchigumo clan's fort protecting a powerful forbidden technique was under attack. With Team Kakashi and Team Kurenai being the closest, Tsunade sent Katsuyu to inform them of their mission to aid the Tsuchigumo clan, in accordance with the peace treaty the Third Hokage made with them. Tsunade later receives word from the teams that they and the clan have considered destroying the technique to end the possible danger it can cause.

Invasion of Pain Arc
When word reaches Konoha of Jiraiya's death, Tsunade makes the village's top priority analyzing the clues Jiraiya left behind about Pain's identity. While the likes of Shizune, Ibiki, and Shikamaru are hard at work, Tsunade allows herself an opportunity to cry for her old friend. Naruto, just as badly affected by Jiraiya's death as Tsunade, went away to train, both of them knowing that he was Pain's next target.

When the invasion of Pain began, Tsunade tried to send word for Naruto to return home. She was stopped by the Konoha Council, who feared his capture by Akatsuki. However, Tsunade insisted that they must have faith in Naruto, along with the rest of the next generation, and so they relented. Tsunade began issuing orders for the village's defence, placing extra protection around those still working on Pain's secret. She summoned Katsuyu, and had her divide and seek out every villager so that she could protect and heal them remotely.

While sitting in the middle of a seal guarded by ANBU, transferring her chakra to Katsuyu, she was found by Pain's Deva Path, whom she recognised as one of the orphans Jiraiya trained in the past. Tsunade refused to tell it where Naruto was, proclaiming that Akatsuki was just a terrorist group. When Pain discovered Naruto's location through other means, the Deva Path resolved to make Tsunade see what Akatsuki's true goals were.

The Deva Path destroys the village. In the few moments between when the destruction began and ended, Tsunade poured all her chakra into Katsuyu in order to keep the inhabitants safe. In the aftermath, she confronted Pain, who attempted to kill her with his Asura Path. It was stopped by Naruto, who informed Tsunade that he would personally deal with Pain. Having used up almost all of her chakra, Tsunade's elderly form resurfaced, she then falls into a coma and does not see Naruto's victory over Pain.

Confining the Jinchūriki Arc
While Tsunade remained in a comatose state, Danzō was chosen to replace her as the Candidate Sixth Hokage. However, he was killed by the now-international criminal Sasuke Uchiha after the Kage Summit and the village prepared to make Kakashi Hatake the new Hokage, but Tsunade woke up before the appointment could be finalised. Tsunade learned of everything that happened while she was in her coma; the start of the Fourth Shinobi World War, the Shinobi Alliance, and the identity of Tobi. After replenishing her chakra levels, she convened a war council to prepare the village for the impending war. In the anime after the war council, she calls a private meeting in her temporary office as they discuss the impending war.

Three days later, Tsunade goes to Kumogakure to meet with the other heads of the Alliance. She is warmly greeted by the Fifth Mizukage while the Third Tsuchikage suggests she retire so that she can finish recuperating. When they get down to business, Tsunade learns that the other Kage have decided to send Naruto and Killer B into hiding to keep them safe from Akatsuki. Tsunade argues against this, believing that the jinchūriki will be valuable assets in the coming war. The other Kage insist that it's for the best and the Fifth Kazekage reminds her that she must also take others' views into consideration. She eventually agrees with their decision, albeit reluctantly. Later, she helps organise the joint armies, placing particular interest in the Logistical Support and Medical Division and the Intelligence Division. In the anime after the meeting with the other heads of the Alliance she requests the Fourth Raikage that B teaches Naruto to achieve the control over the Nine-Tails.

Shinobi World War Arc
Later, Tsunade remains at headquarters with the Raikage and the Tsuchikage, providing input when needed. When the First Division engages several revived ninja, Tsunade is disturbed by the possibility that Dan may be among their numbers. She is later surprised by news of the Gold and Silver Brothers' Nine-Tails chakra.

When news reaches headquarters of Naruto and B's escape from their confinement, the Raikage asks Tsunade to help him deal with them. She summons Katsuyu and leaves it at headquarters, taking a mini-Katsuyu with her so that she and the Raikage can keep up to date on any urgent matters. When they intercept Naruto and B, Tsunade is amazed by Naruto's Nine-Tails Chakra Mode. Naruto appeals to Tsunade to let him and B pass, but she informs him that she can no longer show him special treatment and must do what is best for the Alliance. Naruto tries to escape but is stopped by the Raikage, who voices his willingness to kill Naruto and B if they would not submit. Tsunade however, tells him that she will not allow him to do so.

Turning to face the Raikage instead, she remembers Naruto's words, that he would not die until he became the Hokage, she argues that even if Naruto being killed delayed the enemy's plan, that it's unlikely that another jinchūriki will have the same success as Naruto has had with controlling the Nine-Tails, and going against A's instructions, allows him to pass through. When it seems that A will not be swayed, Tsunade is intent on fighting him, but as it turns out, A was testing Naruto and agrees to let him continue on to the battlefield when he proves himself.

Upon returning to headquarters, Tsunade reviews the data from the medical team and is disconcerted by what Madara Uchiha and Orochimaru had achieved with her grandfather's cells, and concludes that harvesting them is what had allowed Madara to live for so long. When A asks if there are any hints on how to defeat Madara, Tsunade replies by saying that Madara may in fact be the true definition of the word "immortal". She then tells Shikaku to inform Naruto and B about White Zetsu's transformation ability.

Having heard a report from Inoichi about the progress that the Alliance was making on the battlefield after Naruto's release, Shikaku comments that they were gaining the upper hand out there. At this, Tsunade smiles at A triumphantly. They are subsequently told, however, that a new chakra has been sensed in the Fourth Division's area:. This is confirmed to be Madara Uchiha which sends them into confusion. Mabui inquires about the reason behind the masked man assuming the name 'Madara', to which Tsunade responds that, even more than a name, Madara is an ideal which strikes fear into people from just the simple idea of him. A sudden tremor is felt, and after hearing the report from Inoichi that a meteorite had been dropped on the Fourth Division, and hearing Ao say that the lives of several shinobi had been lost, Tsunade decides to head out to the front lines of the battlefield.

Adamant about her decision, she tells Mabui to prepare her Heavenly Transfer Technique to transport her there. Mabui protests however, saying that her technique was not intended for use on living organisms. She comments that the Third Raikage was the only one able to withstand her technique because of his special body. Shikaku also tries to dissuade Tsunade, telling her that it was a huge gamble regardless, and that she wasn't so lucky when it came to gambling and that they should use the Flying Thunder God Technique instead.

Though she admits that she is bad at betting money, she argues that it was different when it came to her life, citing that as the reason why she’s still alive also claiming that they should use the Flying Thunder God Technique to transport Mei, since they needed a way to deal with Madara's Fire Release techniques, and that she would simply use her Yin seal. Despite Mabui’s insistence, A told her to prepare the technique for two, as he would be accompanying Tsunade.

Mabui eventually caves, and uses her technique to send them to the battlefield. Upon their arrival, Tsunade attacks Madara immediately with a kick sending him flying while A dealt with Mū. Sustaining some injuries in transit, she releases the seal on her forehead and uses her Creation Rebirth technique to heal herself. Standing up alongside all the other Kage, she faces Madara prepared to fight.

As the battle with Madara begins, Tsunade states that first she will heal Ōnoki and Gaara's injuries, asking Mei and A to hold off Madara while she does so. As she's healing them, Naruto questions her on why she hasn't collapsed after using Creation Rebirth after she arrived. Tsunade tells him that this instance is different compared to the scale she had to use it on during Pain's invasion, as this time she was only healing her own injuries and they were nowhere near as bad as the injuries she healed during Pain's invasion. Naruto asks to be healed despite being a clone, so he can join the battle but Tsunade tells him there's no need for that — Ōnoki then goes on to explain that the war is no longer just about protecting him. After being completely healed, Ōnoki and Gaara join the battle just in time to protect everyone from Madara's attack. As Madara is downed by the Kage's combined assault, Naruto turns to Tsunade, but is told by Ōnoki that this battle is no longer Naruto's to fight. Tsunade tells Naruto that they can only win if they defeat both Madara — she says that, while they protect him from the revived Madara on this side, he needs to protect them from Tobi. With that, Tsunade and the rest of the Kage give Naruto a message, telling him simply to "win" as the clone disperses.

As the battle wages on, Tsunade seemingly takes a supplementary role as the medical-nin, hanging behind to heal the other Kage whenever they got injured. As Madara uses the Wood Release: Advent of a World of Flowering Trees technique, Tsunade is shocked to see him use her grandfather's technique before calling to Gaara, who suspends them above the attack and then telling the other Kage to ensure they didn't inhale any of the pollen. The Kage however are ambushed and knocked back to the trees by Madara's Susanoo. Inhaling the pollen, they fell unconscious until Ōnoki manages to destroy the trees and part of Madara. Tsunade later stares in shock as she sees the face formed from her grandfather's DNA jutting out of Madara's now-exposed chest.

As Madara regenerates he asks Tsunade if she is a descendant of Hashirama. After this is confirmed, he declares that she would be the first to die. As Mei states that attacking the medical-nin in a team is a common tactic that they'd never allow, Madara tells them that it was not because she is a medical-nin, but because she is a Senju descendant whom he has deemed to be weak in comparison to her grandfather, who could also use medical ninjutsu. After Madara recounts Hashirama's skill with medical ninjutsu, stating that Tsunade's paled in comparison, Tsunade states that even though she is a descendant of Hashirama who could not use Wood Release, and admits that her medical ninjutsu paled in comparison to her grandfather's, whose techniques did not require hand seals, she states that Madara is wrong in thinking that she is a weak woman. She then goes on to declare that more so than the strength she inherited from her grandfather, she inherited his Will of Fire, which Madara should not take so lightly.

As she denounces Madara's claims, she tells him of the four rules she created for her students and medical-nin alike stating that she was the only one who was allowed to break these because of rule number four: only those that had mastered the Creation Rebirth technique were allowed to break the other three rules and engage directly in battle. With this she completely releases her Yin Seal, activates the Strength of a Hundred Technique, and confronts Madara — cracking his Susanoo's ribcage with a single punch. As Madara retorts with a Fire Release: Great Fire Destruction technique, Mei intercepts this and counters with the Water Release: Water Encampment Pillar technique and then sends Madara flying into the air with the Water Release: Water Dragon Bullet Technique. With this, A, Ōnoki and Tsunade prepare a twofold attack which sends Madara plummeting into the ground. Barely giving him time to relent, Tsunade chides him again about inheriting the Will of Fire as opposed to something physical wondering whether or not he was even listening.

Attacking once again, Tsunade is able to land a hit on Madara directly which destroys his entire right side. Seemingly incapacitated enough, Gaara binds and seals him. As Tsunade congratulates the other Kage, her face widens in shock as one of Madara's Susanoo Swords emerge from the ground and impales her. As Madara emerges from a root, he revealed that what they had sealed was nothing but a mere wood clone and that when Hashirama used it during their battles, he was the only one that was able to distinguish the clone with the use of his dōjutsu.

Just as Madara sets his sights on the other Kage — believing her to be dead — Tsunade breaks the sword lodged in her abdomen and, in one fluid motion, swings it at him, who manages to block it by using Susanoo's ribcage. Tsunade is then sent flying back when Madara attacks her with his Yasaka Magatama technique, crashing into a wall. She emerges seemingly unaffected by his attack as her wound heals. Madara praises her for this, and compares her technique to Hashirama's, though she admits that she had just intended to create an opening for an attack, but Madara is also able to nullify Ōnoki's sneak attack.

Jeering Madara, Tsunade states that it was true that he was able to outwit them with his wood clone, but, that at the same time it could be said that they had cornered him into using the clone. This causes Madara to use the Multiple Wood Release Clones Technique, sending five clones to fight each of the Kage. With this he asks them whether or not they'd prefer the clones use Susanoo, much to the Kage's collective shock.

As the battle raged on, Tsunade sends on of the Susanoo-clad clones plumetting into the ground. After A berated her increasingly reckless actions Tsunade reminds him that she had already stated she would bet her life and removed the two broken Susanoo blades from her abdomen. This however, causes her some pain and as she coughs up blood, she is attacked by another clone. Spurred on to stand and fight by Ōnoki once more, the five Kage regroup and launch a new strategy with Tsunade transferring some of her chakra to Ōnoki in order to facilitate his large-scale Dust Release: Detachment of the Primitive World Technique which results in them taking out all twenty-five clones in one shot. After a follow-up combo attack from A, Mei, and Gaara, Madara acknowledges that they are indeed worthy of their Kage titles, and manifests his complete Susanoo. After Susanoo is completed, Tsunade along with the other Kage stare in shock at the humongous construct. Now realising the difference in power between the Kage and Madara, Tsunade wonders whether her grandfather really fought and defeated someone like that before being knock down by a swing of Madara Susanoo's sword. As they regained their footing, she and the other Kage stand to face Madara once more. As Madara prepared to delve another devastating blow with his sword, Tsunade formed a seal, seemingly prepared to counter the attack. However, Madara is then enveloped by a light of sorts and it appears as though he was about to be released, she wonders who could possibly have stopped the Impure World Reincarnation since the Alliance was still in the process of searching for Kabuto.

Ōnoki cautioned his fellow Kage as Madara made a last desperate attempt to attack them, using the Fire Release: Dragon Flame Release Song Technique. Intercepting the attack, Tsunade dissipated the flame dragons with her bare hands. Her arms are burned in the process, and though Strength of a Hundred Technique is able to repair the damage, the technique wore off shortly afterwards and her Yin Seal disappeared as her chakra reserves depleted. As she began to lose consciousness while still in mid-air, Madara prepared to impale her with his Susanoo's sword once again, but Tsunade miraculously dodged the blow. As she wondered what it was that saved her, she heard a voice inside her subconscious where she saw Dan standing before her. He commented that she hadn't changed since he was alive, still taking risks in combat, but then thanked her for achieving what he didn't by becoming Hokage and apologises for bringing so much pain into her life with his death. He stated that he would be waiting for her on the other side, but insisted that she not come too soon, as she was his dream. He left her with a kiss on her forehead, reminiscent of the one she gave him decades before, grateful that he was able to protect her, even if it meant being used in the Impure World Reincarnation. Before departing, he gave her the remainder of his chakra and as the Yin Seal reformed, Madara commented that she has regained her vitality and wondered how that could be, to which she simply replied saying she had met an old friend. With Madara having broken the Impure World Reincarnation technique's contract with the summoner, however, the Kage now faced an opponent with limitless chakra, and an immortal, uncontrolled body.

Creation and Conception
Tsunade's name is taken from the character of the same name from. The Tsunade in that story is vastly different in terms of personality, along with the fact that unlike her manga counterpart the original Tsunade was married to Jiraiya, however both were known to greatly excel in slug magic.
