Sai Yamanaka (山中サイ, Yamanaka Sai) is a Chūbu of Konohagakure's Yamanaka clan. Prior to this, he was an Anbu from Root. As per standard Root training, Sai was conditioned to remove all emotions and as such, had difficulty connecting with others. When he is added to Team Kakashi as a replacement for the rogue Sasuke Uchiha, Sai begins to learn more about people's feelings and tries to develop his personality and identity by forming genuine bonds and rediscovering the emotions he was taught to suppress.
Sai was orphaned as a child and recruited into Root, a secret branch of the Anbu under the leadership of Danzō Shimura. There, he was raised and conditioned to have no personality, personal connections, or a name; "Sai" being given to him for the purposes of joining Team Kakashi. Though largely successful in this regard, Sai retained an interest in art. When Shin, an older Root member, discovered Sai's drawing ability, he encouraged Sai's talent and they became very close.
Over time, Sai came to think of Shin as an older brother and looked up to him. Unfortunately, the final step in Root training called for the two to fight to the death to eradicate all remaining emotions. Before that happened, however, Shin died of an unnamed illness and Sai's Root training suppressed most of the memories he had of him. In the anime, Sai and Shin were forced to fight by Danzō but Shin, knowing that he was dying anyway, told Sai to report to Danzō that he had killed him in battle. Before dying, Shin told his brother that he had to suppress his feelings, and to live for the both of them.
Before Shin's death, Sai created a picture book that would depict all the opponents they faced and illustrate the feelings that they shared for each other. Sai organised the book so that his and Shin's portraits would be located at opposite ends of the book, and in the centre pages would be a picture of them holding hands. Some time after the loss of Shin, Sai forgot that this was his intention, and the picture book was left unfinished, though he could never bring it upon himself to discard the book.
During his time in Root, Sai was ordered to eliminate a large number of individuals that posed a threat against Konoha. At the time he was assigned to Team Kakashi, the last assassination he performed was of Unmo Samidare. In the anime, an attempt to gain a powerful fūinjutsu after seeing the Third Hokage sacrifice his life in an attempt to defeat Orochimaru, led Danzō to supervise Sai while he learned how to use the Sealing Technique: Tiger Vision Staring Bullet, noting that it would be dangerous as he would have to use "emotional energy" in order to make the technique stronger. Sai struggled greatly with this endeavour as it conflicted with his training and, consumed by negative emotions, his training was seemingly left incomplete.
When first introduced, Sai was distinguished by his total lack of emotion which he often masks with a false, cheerful, yet transparent façade. After much mental conditioning and training while in Root, Sai had suppressed almost all of his emotions, laying all of his loyalty to whoever commands him, and thus making it easier for him to accomplish dangerous, unpleasant, or unethical missions. Due to this training and his lack of social experience and personal initiative, Sai has great trouble in understanding how bonds between people can motivate others. He often showcases this confusion after thinking about why Naruto would go so far to save Sasuke, a traitor, even though Naruto had not been ordered to do so.
Sai's social awkwardness tends to get people angry, because he often speaks without considering his words and their effects on people. This was due to his inability to realise the difference between a rude statement and a true statement. Sai had read somewhere in a book that giving somebody a nickname would bring you closer to that person and develop your friendship, this resulted in Sai hurting Sakura Haruno's feelings, because he called her "ugly", stating the first true character trait that came to his mind. This also nearly led to enraging Chōji, while eating barbecue with Team Asuma and Team Kakashi he nearly called him "fatso" before Naruto covered his mouth before he could finish. Realising he was offending people by saying characteristics that came to his head, Sai decided to take a different approach by saying the opposite of what came into his head. In this way, at the same event, Sai called Ino "gorgeous" (although he truly meant to call her "ugly"), much to Ino's surprise, Naruto's relief, and Sakura's outrage.
After spending more time with Team Kakashi, Sai comes to appreciate bonds, particularly the bond that exists between Naruto Uzumaki and Sasuke Uchiha, though Sai would come to have serious doubts about Sasuke when he began to commit crimes on an international scale, which Naruto would suffer for, leading him to support assassinating Sasuke. This causes him to break out of his emotionless shell and start to remember the times he had with his own "brother", Shin. In doing so, Sai was able to start giving genuine smiles. Wanting to experience personal bonds for himself, Sai sets out to make as many friends as he can. However, since he is learning most of this out of books and by trial and error, he often accidentally ends up offending people with his nicknames and conversation. He has come to develop a more genuine, pleasant, and thoughtful personality, while also showing signs of more emotion, such as enthusiasm and occasional nervousness. In the anime, it was shown from his Infinite Tsukuyomi dream that his greatest desire is to fully rediscover his emotions and connect with as many people as possible through it.
He later appeared to show genuine anger while explaining to Sakura about Naruto's feelings for her and later when she lied to Naruto about the predicament with Sasuke and trying to use a fake confession to get him to give up on Sasuke. The greatest change in his personality, however, came after he encounters his reincarnated brother. When Shin is used as a living bomb by Deidara, Sai became truly enraged for the first time and attacked Sasori and Deidara mercilessly, showing genuine rage on his face. Sai also displayed genuine sadness, shedding tears when his brother was freed from the technique and disappears.
Sai is very observant, and is always focused on his missions. He pays a lot of attention to detail, allowing him to quickly notice if something is not as it appears, as shown from how he easily sees through Yamato's tricks. This awareness spans beyond the trials of duty, as Sai was later quick to understand the nature of Naruto's inner suffering without Naruto even telling him. What he failed to understand, however, was that Naruto was not trying to save Sasuke just for Sakura, something he mentions is due to his still lacklustre understanding of both his Team 7 teammates and emotions in general and he would come to regret when it lead to Sakura's suicidal attempt to stop Sasuke, feeling that as if he was a true friend, he should've found another way that didn't put his teammates at risk. Sai holds Naruto in high regard and tries to assist Naruto whenever he's going through hardships however he can.
This bond with Naruto led Sai to start to understand camaraderie, and by the Fourth Shinobi World War, he realised he understood it as he, Rock Lee, and various others went to assist Naruto as he fought against Tobi. Growing up over the following the years, Sai came to truly understand compassion and love, forming a closer bond with Ino, showing more forwardness in such acts as asking her on a date and holding her hand affectionately. This ultimately led to them forming a family. Through all this, Sai has completely come to reject the teachings of Root, accepting that Danzō's actions, while genuine to protect the village, were misguided and only led to more suffering.
Sai is shown to care greatly for his family, as he has begun training his son in his artistic-ninjutsu, finding humour in Inojin's cruder drawing. Sai also has developed strong parenting skills, being the one who's reprimanding Naruto for not holding back enough when he tried to counter Boruto's shadow clone with his own. His compassion for his son's happiness was also shown from not wanting to hurt any of his friends, regardless of the circumstances. He also believes in a indirect teaching-method, feeling that while people need guidance, they cannot truly grow as people if they don't find the answers themselves.
Sai has short, straight black hair, and dark eyes which contrast with his translucent-looking pale skin. He is usually seen carrying a small backpack with his brush, scrolls, and ninja ink in it. He wears a short black-and-grey jacket with red straps — as customary of all Root members, to most likely show his allegiance to the organisation. He also carries a tip-less tantō on his back. The rest of his outfit consisted of a high-collared midriff shirt, black pants, shinobi sandals and gloves with his index and thumb fingers exposed, most likely to facilitate the use of his drawing based techniques. When first seen with Team Kakashi, his jacket has a long right and short left sleeves. He had Danzō's cursed seal on the back of his tongue until Danzō's death, which caused it to disappear. Despite his different hair-style and skin-tone, he is noted by many to physically resembled Sasuke, and ultimately is considered very handsome, as shown from Ino immediate infatuation of him. When he's not on missions, Sai wears a casual outfit consisting of a long-sleeve shirt with a high collar, matching pants, and his regular shinobi sandals. This outfit was first depicted as being purple in colour and later, navy blue. He doesn't wear his forehead protector or gloves with this outfit.
In the anime, when Sai uses the Sealing Technique: Tiger Vision Staring Bullet and his negative emotions surface because of his use of "emotional energy", his eyes turn a translucent red colour and his sclerae turn black. This is apparently, as when Danzō countered the symptoms, ink splattered from Sai's body.
Two years after the Fourth Shinobi World War, Sai grew his hair longer with his bangs framing his face. His attire is similar to his old Root outfit but his jacket is now completely black with both sleeves of his shirt long, and less of his midriff exposed. He also has a large scroll strapped horizontally to his back and his shinobi sandals reach above his calves.
A decade after the Fourth Shinobi World War, his jacket now covers his entire upper body, with both sleeves long. His hair is shorter, and he wears an even larger scroll on his back to perform fūinjutsu. Sai keeps his hair in a short ponytail as customary of the Yamanaka Clan. He has a different styled jacket with the sleeves rolled up and his collar is upturned. The large scroll he carries is attached to his belt and he also wears gloves. He occasionally still uses his forehead protector.
As a member of Root, Sai is a highly capable shinobi, who is trained in the organisation's kenjutsu. Being said to be strongest Root member of his generation, Danzō had enough faith in Sai's abilities to task him with single-handedly killing Sasuke. By adulthood, his talents led him to become one of Konohagakure's top authorities, regular reporting directly to the Seventh Hokage and aiding him in various decisions.
Sai is able to use Earth Release to conceal himself underground without disrupting the surface of the earth. He can also use Fire, Water and Yang Release. In adulthood, since marrying into the Yamanaka clan, Sai appears to have become well-versed (or at least knowledgeable) in their hiden techniques to aid his son's training in them.
Sai is able to combine ink with the Body Flicker Technique to create a more effective cover up. However, Sai's most notable talent is his skill as an artist, able to create drawings in mere moments. He uses these artistic skills as a source for his Super Beast Imitating Drawing. Using his custom scroll (which contains a compartment for Sai's ink brush and a supply of ink), and applying chakra into the drawings, his creations come to life.
Sai typically creates giant birds to transport himself or others, lion-like monsters for attack, snakes for restraining enemies, and mice to scout an area. Sai can also create ink clones of himself for reconnaissance. For discreet communiques when he is undercover, Sai is able to turn the words he writes into small animals, allowing them to travel to their intended target unnoticed. He has also demonstrated the ability to create large humanoids that resemble the Benevolent Kings (仁王, Niō), which possess enough strength to completely destroy Deidara's clay birds. Sai can also add explosive tags to his ink drawings, as seen when he had multiple birds fly down to bombard his enemies with a chain of explosions.
As noted by Kakashi, Sai is one of Danzō's prized soldiers and as such, his Root training also included learning fūinjutsu. By animating a large tiger from his scroll, he can use it to grab and seal the target in the painting. Due to the preparation time it would take to paint the tiger, he would need allies to protect him while in battle. In the anime, it is stated that Sai uses "emotional energy" to bolster the technique. This is a double-edged sword as Sai becomes susceptible to his negative emotions.
Despite not being his speciality, Sai has shown to be proficient in taijutsu. He was able to react and block Naruto's attempt to stab him with a kunai very easily with his tantō. He also was able to subdue Kabuto Yakushi very easily and block Sasuke Uchiha's attempt to stab Naruto, with Sasuke commenting that he blocked the attack in the most appropriate manner. During the Fourth Shinobi World War, he was able to break Shin's neck with a flying knee kick in mid-air. Even without the use of his tantō, he has shown great skill with a bladed weapon and was able to fight equally with an opponent wielding a larger weapon. A distinct advantage he has in battle is to perform techniques with a single hand, leaving the other free for enemy counter-attacks.
Tenchi Bridge Reconnaissance Mission
Main article: Tenchi Bridge Reconnaissance Mission
Sai was assigned to join Team Kakashi by his superior Danzō to assist in meeting with a spy in Orochimaru's ranks to find out about Sasuke Uchiha. Sai was confrontational with his new teammates upon their first meeting, exasperating both Sakura and Naruto. On their way to the rendezvous point, Sai once again aggravated them, questioning Naruto's manhood and insulting Sasuke. The latter caused Sakura Haruno to punch him in anger. As they continued on to the meeting point, Sai questioned why Naruto was loyal to a traitor like Sasuke, to which Naruto stated he was not a traitor, but a friend. Upon reaching the designated meeting place, Yamato went ahead disguised as Sasori so that he could meet the spy. When the spy, Kabuto Yakushi, arrived with Orochimaru to kill Sasori, Sai, Naruto, and Sakura were called in for help.
When Naruto and Orochimaru began fighting, Sai left the rest of the team to begin his real mission. He briefly observed Naruto's fight with Orochimaru, unconcerned with the danger he left Yamato and Sakura in, and approached Orochimaru after he had repelled Naruto with a proposition from Danzō. Orochimaru accepted, and Sai accompanied him and Kabuto back to their hideout. Once arrived at Orochimaru's hideout, Sai was introduced to Sasuke, who had been training under Orochimaru for the past two-and-a-half years. When Sai mentioned that he might get along better with Sasuke than he did Naruto, Sasuke temporally traps Sai within a genjutsu which startles Sai to the ground due to the amount of fear it gave his emotionless self. He was led to his own room afterwards by Kabuto, who locked Sai in upon leaving. Soon afterwards, Team Kakashi tracked Sai down and confronted him about his real mission. Having been caught, Sai explained that he had been assigned to ally with Orochimaru on Danzō's behalf so that the two may join forces in destroying Konohagakure.
Disgusted by the ramifications of this plan, Team Kakashi restrained Sai before setting out to find and retrieve Sasuke. Sai, however, doubted their success, stating that Sasuke no longer cared about them. Naruto, in response, stated that he also used to hate Sasuke, but over time he had formed a bond with Sasuke through their shared experiences, and as such he would do whatever it took to bring Sasuke home. Naruto's dedication to retrieving Sasuke struck a chord with Sai, who was left without words as a result. When Kabuto arrived and freed Sai, Sai instead helped them capturing Kabuto, hoping to accompany Naruto to find out more about bonds. Naruto and Sai split away from Sakura and Yamato to go looking for Sasuke. They were soon found by Orochimaru, and as a result, Naruto distracted him so that Sai could have a chance to scout on ahead. When Orochimaru retreated and Naruto reunited with Sakura and Yamato, Yamato went through the belongings that Sai had left behind. In doing so he discovered Sai's actual mission: to kill Sasuke as a traitor to Konoha.
Team Kakashi raced through the base to find and stop Sai, but Sai had already found Sasuke. Sai, however, truly had a change of heart, and instead, tried to capture Sasuke in order to protect his bond with Naruto. Irritated by Sai's reasons for bothering him, Sasuke attacked Sai, drawing the rest of the team to their location. When they found out what Sai was trying to do, they all teamed up to restrain Sasuke. Although Sai was able to land a successful attack, Sasuke's abilities were too much for them and he prepared to kill them all. He was soon stopped by Orochimaru and Kabuto, who convinced him to spare the team before leaving. Defeated, Team Kakashi returned home. Sai requested that he be allowed to stay as a part of the team and, with Danzō's approval, began to spend time with his new friends. Upon returning to Konoha and failing their mission, Sai began reading about relationships in the hopes of making some for himself.
Twelve Guardian Ninja
Main article: Twelve Guardian Ninja In the anime, Team Yamato are sent to help guard anymore tombs of the former Twelve Guardian Ninja from being robbed. Shortly after arriving at the Fire Temple, the team are notified that another tomb has been robbed. The team then set out to find the perpetrators, accompanied by Chiriku and Sora. Along the way they spot caskets moving across a field and onto a cliff where four ninja lied. When they confront the enemy ninja, Fudō traps them in a rocky canyon, which separates everyone. As Sai tries to look for a way out, Fuen halts his attempts each time. He soon figures out that he is being tracked with a chip and plants it on a ink clone. This deceives Fuen, giving Sai the opportunity to sneak attack her from behind with ink lions. Although she is able to counter, Sai is able to escape.
Some time after, Sai stumbles into Sakura, arriving in time to save her from a surprise attack from a giant spider. While he manages to kill it, he gets injured in the process. Sakura tends to his wound, but he is forced to wear an arm brace. After the two meet up with Yamato, they find Naruto being drained of his chakra by Fūka. Before they can do anything, Chiriku and his fellow ninja monks blast the cave open. Deciding that they had stalled enough, the enemy ninja retreat.
When the group returned to the village, Sai was sent to the hospital to be further treated. While Sai was on leave of absence, Sora took his place. Later, Sai sees that the village is being attacked, and sneaks out of the hospital to help Asuma fight Kazuma, enabling Asuma to finish him off.
Akatsuki Suppression Mission
Main article: Akatsuki Suppression Mission Sai and the rest of team Kakashi were later sent as backup for Team Asuma during their battle with Akatsuki. Because Shikamaru Nara was separated from the rest of the group, Sai and Sakura were sent to his aid, though upon arrival they found that Shikamaru had already defeated his opponent. Sai returned with everyone else to Konoha, having not taken part in the battle. Because Naruto was injured during the battle, he has difficulty eating when they got back. Sai, wanting to ameliorate their friendship, attempted to feed Naruto which angered him since he had wanted Sakura to feed him and Sai had interrupted her doing so. Neither has their way as Kakashi himself took up the task of feeding Naruto instead.
Main article: Three-Tails' Appearance In the anime, Sai was placed on Team One along with Kakashi, Shino and Naruto. His team's duty was to fight any enemies who closed into the area so they wouldn't disrupt the sealing process for Team Three, who were going to seal the Three-Tails. After he had introduced himself to Shino, he found that Shino had a bit of a grudge towards Naruto, since it turned out that though Sai only knew Naruto for a few month and knew more about Naruto, much more than he did. Sai's team ran into Guren and Gozu. As the battle between them commenced, Sai soon took on Gozu alone. Sai managed to temporarily restrain him with his ink snakes but with his brute strength broke free shortly after. The sealing is disrupted and they were forced to retreat and devise another plan.
After he and the other Konoha-nin recuperated, he mistakenly got in between Sakura and Ino's bickering, and by being oblivious to the situation, repeated the names they yelled at each other thus getting himself punched by both of them. He and the others at some point find out that the young boy accompanying the enemies can partially control the beast. They eventually find him unconscious and take him with them. After Yūkimaru was treated by Sakura and Ino, Kakashi decided to use him to conjure up the beast to try sealing once more. After that Sai was tasked with bringing him to an secure place. However, he got attacked by some of Guren's men and despite his efforts, he was defeated and Yūkimaru was captured. Later, he battled foes who were merged but were crushed by the Three-Tails on its ramapage. Having failed to seal the beast again, they returned to their village and left the rest up to the leaf Anbu.
Itachi Pursuit Mission
Main article: Itachi Pursuit Mission
Along with Team Kurenai, Sai and the rest of Team Kakashi set out to find and capture Itachi Uchiha. When Kakashi summoned his ninken to assist them on the mission, Sai was partnered with Ūhei and Urushi and wondered to himself whether or not he could become friends with dogs.
Fated Battle Between Brothers
Main article: Fated Battle Between Brothers He and the other members of the Eight Man Squad were later confronted by Tobi, who stalled them long enough to prevent them from locating neither Sasuke nor Itachi.
Main article: Six-Tails Unleashed In the anime, Sai and the rest of Team Kakashi was assigned a mission involving the Tsuchigumo Clan. When they reached their destination they found the place a wreck and a hurt Tonbee. Sakura healed him and when he regained his strength, he told them that a group of ninja attacked, seeking the Tsuchigumo clan's kinjutsu, and that his granddaughter, Hotaru, escaped through a secret passage with it. Sai, Naruto and Yamato left to find her, leaving Sakura to look after Tonbee. When he, Yamato and Naruto caught up with her, they saw a mysterious guy named Utakata near her. Naruto attacked him under the impression he was a enemy to which it was clarified he was only escorting her until Konoha arrived. Utakata then left Hotaru in their hands, however, she was refused to it and Sai tricked her into letting them escort her to the Tsuchigumo Village. When the group reached the village they left her with the rest of her clan. They returned when they considered the villagers attitude toward Hotaru suspicious, and found she was gone.
Later, Sai and Naruto battled a few Kiri-Anbu because they were attacking Utakata who had Hotaru with him. The leader of the Kiri-nin took Yamato aside to discuss the matters of Utakata. After matters are solved to a certain degree, the groups departed. Sai and the rest soon find out that Hotaru had a scroll that held her clan's kinjutsu embedded in her back, much to the Konoha-nin's surprise.
Some time after, Team Kakashi and Utakata headed to the Tsuchigumo Village again after Hotaru had been kidnapped. While there, Sai, Yamato and Sakura fought the Tsuchigumo clan villagers who were under Shiranami's control and the Magaki Group while Naruto and Utakata went find Hotaru. They departed after Shiranami was defeated and his plan failed.
Main article: Pain's Assault When Naruto entered the Hokage's office, he was seen with Sakura, the toads, Shizune and the Hokage as Naruto learned of his master's demise. During Pain's assault on Konoha, Sai was away with Yamato and Anko Mitarashi, tracking down Kabuto Yakushi. He used a special tracking technique that could not be detected by Kabuto. Anko even congratulated him for that. They stopped the search just after a surprised Yamato had informed the group that Naruto had reached the six-tailed form of the Nine-Tails.
Five Kage Summit
Main article: Five Kage Summit
After the invasion, Danzō is made Hokage. He summoned Sai before him and instructed him to keep an eye on Naruto. Sai asked why, so Danzō explained that Naruto, having defeated Pain, was now the village's hero and thus more popular than Danzō himself. However, he was still the village's jinchūriki and therefore must be kept in check. Sai was satisfied with his explanation and went to meet with Naruto and Sakura. The two immediately confronted him about Danzō, asking him to tell them everything he knew. Sai said that he could not, as the cursed seal Danzō had placed on his tongue prevented him from revealing anything about Root. Sakura remarked it was cruel, but Sai explained that it was for the best since Root had done a number of questionable things to protect the village. Sakura refuted his claim, pointing out that Danzō had ordered Sasuke be killed as a traitor. Sai was surprised since Danzō had not told him that during their meeting. They were immediately confronted by Kumogakure ninja who, after their brief skirmish, demand to know what they knew about Sasuke. Naruto, seeing that this upset Sakura, volunteered to tell them all that he knew. Sai secretly watched the meeting and how Naruto could not bring himself to sell out Sasuke.
Naruto allowed Karui to take out her anger on him. Karui happily accepted and proceeded to beat him up, but Sai stepped in once she started to overdo it. When Karui left, Sai brought Naruto to Kakashi and Yamato and then tended to his wounds. Naruto asked that Kakashi and Yamato help him find the Fourth Raikage. When they had agreed, Kakashi told Sai not to tell Danzō what Naruto was doing. After hearing such a request Sai looked rather upset and asked Kakashi if he didn't trust him because he was from Root, but Kakashi answered that he believed in him because he was also a member of Team Kakashi. Hearing these words made Sai happy and drove him to act more resolutely. Sai, after deciding to no longer be just reactive while Naruto is suffering from the current events, later approached Sakura, telling her about what Naruto had gone through with Karui for her benefit. He told Sakura that Naruto loved her, and that trying to make her happy, such as trying to bring Sasuke back to the village, caused him to feel anger, pain and suffering.
Following the Konoha 11's decision to eliminate Sasuke themselves to prevent a war, Sakura asked Sai to help her track down Naruto so that she could speak with him. They found him in the Land of Iron and Sakura confessed her love to Naruto, so now he didn't need to bother fulfilling his promise of retrieving Sasuke. When Naruto didn't believe her, Sakura left with her group. Because she didn't mention the decision to kill Sasuke and that he felt responsible for what she was about to do because of what he had told her back in Konoha, he left an ink clone behind to tell them what Sakura had not. The clone also added that Sakura was likely planning to kill Sasuke personally.
The ink clone helped Kakashi locate Sakura. The real Sai, meanwhile, stopped Sakura from knocking him out and her other escorts, having suspected that she would try to get rid of them so she could fight Sasuke alone. Sakura convinced Kiba and Lee that Sai was a traitor and they started to fight him, but this only made it easier for her to knock out all three. As the ink clone dispersed it warned Kakashi of Sakura's actions. Sai and the others were later woken following the meeting with Sasuke, and as they return to the village they were met by three Root members. They inquired about what had happened. Sai affirmed that the seal disappearing was proof that Danzō had died. He then encouraged them to speak with Kakashi whom he addressed as the "new Hokage" about Root's future.
Main article: Power In the anime, Sai and the rest Team Kakashi were sent to investigate the attack at Tonika Village. Splitting up into two, he goes with Yamato. While on their investigation they run into police from Hachō Village. After hearing an explosion from a distance he and the others go to the location. When arriving he battled Kabuto at first but soon enough a reincarnated Deidara stepped in and his attention was drawn to him. After Kabuto retreated he and Yamato went to gather information on The Hole.
While there, he and Yamato soon battled Deidara and a snake clone of Hidan. Later with assistance from Kakashi and the other Konoha-nin, they discussed Kabuto's possible intentions. After, he joined his comrades in battling Kabuto's reincarnated shinobi. Later, they all returned to Konoha, with Kabuto's plan failed.

Fourth Shinobi World War: Confrontation
Main article: Fourth Shinobi World War: Confrontation
When the Fourth Shinobi World War began, Sai was placed in the Surprise Attack Division. He created birds with his Super Beast Imitating Drawing for his Division to head into battle. When they entered the enemy's territory and the rest of the division began making a base camp, Sai took to the air to provide back up in case they were attacked. When he later spotted several explosions near the camp, Sai rushed back, eliminating one enemy as he arrived. Despite having a broken neck, the target got back up, revealing himself to be a reincarnated Shin. Shin apologised to his brother for being forced to fight him, unable to control his own movements because of the technique he was reincarnated with and because he was also being manipulated by Sasori. Sai and Shin traded blows until the rest of ambush team could come to help. Hoheto Hyūga revealed that there was explosive clay stored within Shin. They navigated him into one of Kankurō's puppets before he could detonate, weakening the explosion.
However, the force was still great enough to knock Sai over, causing some of the belongings from his bag to fall out. Shin regenerated from the damage and Deidara promised to use Shin as a human bomb again and again. Enraged, Sai quickly navigated behind Deidara and Sasori and drew two ink warriors that knocked them both into two more of Kankurō's puppets, where they were confined and neutralised. Sai then prepared to fight Shin again, but Shin told him there was no need; Sai had dropped his picture book earlier, and seeing the finished product had unbound his soul, freeing him of the regrets that he had had in life. Tears flowed from Sai's eyes as Shin's body turns to ash and dust.
Sai, Omoi, and Zaji were sent out to find other Akatsuki cells. When they came across a group consisting of Haku, Zabuza, Gari, and Pakura, Sai created several ink birds with explosive tags attached to bombard them with. Although the revived ninja recovered from their injuries, Sai continued the assault until backup could arrive. Haku managed to destroy the birds they were riding on, causing them to fall to the ground. Before they could be killed, fortunately, the Third Division arrived to help. They later joined the division in protecting Kakashi as he executed his strategy. After Zabuza and Haku had been dealt with, Kakashi asked that Sai back him up with the sealing techniques he had learned from Root. Sai was reluctant, but Kakashi insisted that, as one of Danzō's most prized soldiers, Sai needn't hold his emotions. Later, Sai was seen among the rest of the Third Division as they recuperated after the first day of war.
Fourth Shinobi World War: Climax
Main article: Fourth Shinobi World War: Climax
The next morning, Sai alongside the Third Division restarted their assault on the Seven Ninja Swordsmen of the Mist. Drawing a gigantic tiger, Sai launched his Sealing Technique: Tiger Vision Staring Bullet at Fuguki Suikazan who had been incapacitated by Kakashi. As the tiger dragged Fuguki back into the drawing, a noticeably winded Sai told them that he could still go on. Lee told Sai to just concentrate on sealing the enemies, he would protect him while Sai's at it. As a new wave of White Zetsu Army clones approached, Sai looked on as Naruto's shadow clone arrived on the battlefield to confront them. In the anime, Sai also used this technique to seal away Jinin Akebino, and a number of other reincarnated shinobi as well. After being informed by Inoichi from HQ that Naruto and B were fighting the "masked Madara", Sai and the Konoha 11 rushed to his aid. As he ran, he stated that if it were not raining, he could use his Super Beast Imitating Drawing technique to get to Naruto faster. After Lee had, however, spurred him on, Sai thought to himself that he finally and completely understood what it meant to have friends.
Upon arriving at the battlefield, he apologised to Kakashi for their late arrival and later stood alongside the remaining members of the Allied Shinobi Forces to face their opposition. When B had regained enough chakra, Sai flew him towards the Ten-Tails atop one of his birds, allowing B to get close enough to launch a counter measure against the beast.
Later as the Ten-Tails matured and the Alliance launched a counter assault, Sai attempted to attack the Ten-Tails' body from above, avoiding its copies, but was soon spotted and knocked out of the sky. After being saved by Naruto, Sai concluded the only way to reach the beast was to take out the larger enemies first and slither past, but that would require a method to get into range quickly and once they were there they would be without healers. His teammates of Team Kakashi responded by summoning a snake, a toad, and a slug respectively.
While the Allied Shinobi Forces and the deceased Hokage marvelled at the original Team 7's combined performance, Sai questioned Jūgo about Sasuke's true motives, to which he replied that even he himself didn't know. He would later tell Sakura that since he didn't know Sasuke much he could observe him without friendly feelings involved and that he couldn't trust him. He proceeded to question Sakura how she truly felt about Sasuke, to which she replied that she was happy Sasuke had returned and that they could trust him. Sai then thought that sincere as her words sounded, her smile was fake.
Birth of the Ten-Tails' Jinchūriki
Main article: Birth of the Ten-Tails' Jinchūriki
After the Ten-Tails transforms into its true, tree-like form, it ravaged the Alliance in an attempt to consume their chakra. Sai, seemingly having avoided the assault, crouched and tended to a wounded Sakura. Thankful that Sakura was all right, their attention is soon drawn to Shikamaru's predicament. When Katsuyu noted that it would not be able to remotely assist him because its clones had been killed as well, Sai and Sakura rushed to Shikamaru's side to help their fallen comrade. Responding when Naruto called for them telepathically, Sai the Konoha 11 shinobi are shocked when Naruto's Tailed Beast Mode mantle forms around them as well when he enters one of Kurama's tails. His directives clear, Sai and the others used the Rasengan, which Naruto had formed to break down Obito's defence and give Sasuke and Naruto a clear shot at attacking their opponent. He and his comrades later also aided Naruto in wresting control of the tailed beasts' chakra from Obito in order to stop the Ten-Tails' tree form from blooming. Ultimately, they succeed in removing the tailed beasts from Obito, reverting the Uchiha to his original form. Sai then joins the others in aiding Hashirama against Madara.
After Hashirama is able to subdue the Uchiha, Sai moves in to seal him for good. Moments before the seal is complete, Madara has Black Zetsu merge with Obito, forcing him to revive Madara, granting Madara full access to his newfound might and break free of both Sai's seal and Hashirama's restraints. After being revived and gaining access to his full power, though without his dōjutsu, Madara was easily able to overwhelm the shinobi in the surrounding area, including Sai, before absorbing Hashirama's senjutsu chakra and going to capture the nine tailed beasts. Sai then teamed up with Sasuke, letting the Uchiha perform a sneak attack from the air through the use of a ink bird.
Much later, after Madara became the Ten-Tails' jinchūriki and reclaimed his missing eye, Sai stood next to Hashirama while the Infinite Tsukuyomi was cast, before falling prey to it like the rest of the world and being captured by the roots of the Ten-Tails. In the anime, he dreamed of perfecting his natural smile and expressing himself, to which he made friends with everyone who loved his smile.

Sakura Hiden: Thoughts of Love, Riding Upon a Spring Breeze
Main article: Sakura Hiden: Thoughts of Love, Riding Upon a Spring Breeze Kakashi meets with Sai and tells him about two separate attacks by unknown perpetrators against the Fire daimyō and Homura Mitokado. Although nobody was badly hurt and there's no proof the two attacks are connected, Kakashi wants Sai to investigate both incidents by himself.
Sai meets with an informant just outside of Konoha and sends him to investigate if some criminals listed in the Bingo Book are behind the two attacks. As he returns to the village, Sai is attacked by two masked individuals. Although each of the attackers has a cloak of tailed beast chakra, he is able to drive one of them off and capture the other. Sai starts questioning the captive, but when the man begins to respond a juinjutsu activates and his body blows up. Sai reports this to Kakashi. Both observe that the attacker's suicidal juinjutsu is similar to what Danzō Shimura used on his agents. This, combined with the fact that nobody but an Anbu could have even guessed Sai's assignment and thus known to attack him, convinces Kakashi that it is all part of a scheme concocted by Kido Tsumiki, a former ally to Danzō. Kakashi instructs Sai to focus his investigation on Kido.
Sai follows Kido's movements between his different hideouts for three days, but he has no way of getting inside any of them without revealing his presence. His informant requests a meeting and, there, reports a rumour about Sasuke: that he approached some arms dealers several weeks earlier seeking weapons for an attack on Konoha, and then killed the dealers when they failed to cooperate. He also reveals that, after the war, he saw Anbu collecting samples from the Valley of the End and the bridge where Sasuke fought Danzō. Sai pays him for this information and requests another meeting in the future.
When it becomes clear that Sai's investigation into Kido is the same as Sakura and Ino's investigation into an impostor of Sasuke, Kakashi merges their investigations. Ino dubs themselves Ino–Saku–Sai and they promise to keep each other informed of their findings. Shortly afterwards, Ino visits Sai at his home to inform him that Sakura has been captured by Kido. Sai and Ino go to one of Kido's hideouts and Ino senses the interior for Sakura's chakra. She isn't there, but Sai decides they should see what intel they can get anyway. Ino uses the Mind Body Switch Technique on the hideout's sentry while Sai captures them, her first time using such a tactic without Shikamaru and Chōji. When the sentry, an acquaintance of Sai's, is unwilling to answer their questions, Sai forces Sakura's whereabouts from him by tickling him with a paintbrush. They go to the hideout where Sakura is being kept on Sai's imitating bird. When they arrive they find that Sakura has already escaped and is on the offensive.
Sakura, Sai, and Ino work well together despite being outnumbered. They defeat all their opponents but Kido and Magire. Since Magire is a medic-nin, they decide to separate Kido from him so that Magire can't heal his injuries. Sai and Ino exchange attacks with Magire, but neither side is able to hit the other. Magire activates a synthetic tailed beast cloak and, with its tails, is able to create glowing orbs that detonate on contact. While Sai tries and fails to overpower Magire with his Super Beast Imitating Drawings, Ino takes control of an eagle which she uses to stab Magire from behind with a poisoned kunai. Magire's movements slowed, allowing Sai to deliver a finishing blow. Kakashi arrives to help soon after Magire is defeated, with Naruto and Hinata accompanying him. Together, they head into the forest to help Sakura. However, she defeat Kido with her Cherry Blossom Impact. Their mission completed, Ino–Saku–Sai disbands.

Academy Entrance Arc
Main article: Academy Entrance Arc In the anime, as mysterious attacks began happening more commonly and expanding in area, Sai was called to help in the investigation. He later found evidence to suggest that the real goal of the perpetrator was to harvest people's chakra. It was also discovered that the Wood Release was possibly involved. As Root had a history of conducting its own secret research on the famed power of the First Hokage, Sai went to research more of the disbanded Anbu unit alongside Shikamaru. As the attacks continued to occur, Sai intensified his efforts. While Naruto told him to calm down, Sai was determined to save the potential culprit from following the misguided ideology of Root.
Later, a strange release of chakra began spreading throughout the village. As it showed a similar nature to the chakra of the rampages, Sai went to act. His investigation led to an old facility of Root, which turned out to be the hideout of the late-Tanuki Shigaraki, one of Danzō's top researchers and most loyal followers. Putting the pieces together, Sai remembered that Tanuki was in charge of creating an ultimate weapon made from the First Hokage's cells. While looking around the demolished building, he found a picture of Tanuki, with a young girl Sai immediately recognised as Sumire Kakei. After reporting his findings to Naruto, Sai and his unit went in search of Sumire, who disappeared from the hospital. Sai soon found her and subdued her. While preparing to take her in, she unleashed the Nue. The rampaging beast gave Sumire the chance to escape while Sai and his unit attempted to hold off the beast. Kakashi soon appeared, severing its tail, only for the creature to sprout dozens of smaller tails and steal people's chakra. As Kakashi organised the unit to hold off the creature, it suddenly teleported away.
Kakashi deduced that the creature acts differently from normal summonings, naturally existing in its own separate dimension. By morning, Sumire returned from the separate dimension along with Boruto and Mitsuki. Sai, still sympathising with Sumire's history with Root, offered to help her forge a new brighter path. Having let got of her anger at the village thanks to Boruto's words, Sumire accepted Sai's offer and peacefully turned herself in. Sai promised Boruto that she would be fine. Later, Sai discussed the future of Sumire with Naruto and Shikamaru. Sai also removed Sumire's Academy records to weigh in their options.

When Naruto revealed to the others Mitsuki was in fact Orochimaru's son, much outrage followed from learning that Naruto would permit an offspring of the man who killed the Third Hokage live in Konohagakure, let alone keep it a secret. Naruto rationalised this on the grounds that Orochimaru's conduct as changed from before and that his aid in investigating the Ōtsutsuki.

He also said that the marks' nature is vaguely similar to Orochimaru's Juinjutsu.
Kara Actuation Arc
Main article: Kara Actuation Arc In the anime, after Sasuke finished probing Shojoji's mind, he learned that Kara was apparently last seen hidden in Amegakure.

As they entered the area, there were assaulted by Garashi Tōno, an orphaned citizen of Amegakure. He insisted that they were enemies who killed his friends. Sai however quickly subdued him and explained their situation. Calming down, Garashi explained how a group of people were conducting an experiment underground. When he and his friends went to spy on the strangers, they were spotted and gas was set off to kill them. Garashi agreed to take them through the tunnels. This however turned out to be a trap, as Garashi ensnared the Konoha-nin and gassed them, revealing him to be a supporter of Kara after the struggles he had to endure since the Fourth Shinobi World War. Sai and Sasuke saw through his deception and used shadow clones to bait him. Before they could get information from him, Garashi was tricked also by Kara, as his gas mask was tampered with and he succumbed to the poison gas. As the tunnels began to collapse from another trap, they learned that Kara had been stationed there and was performing biological experiments. Sai and Sasuke reported their findings to Konohagakure. Sai asks Naruto if he has read Ino's report on Katasuke.

As the boy began opening up to people, Naruto decided to teach him ninjutsu at his request. During training, Sai and Shikamaru discussed whether or not they could really trust Kawaki. Sai felt they didn't have enough information to make any conclusion. He also informed Shikamaru they were able to recover coordinates from the intel retrieved by Konohamaru, and despite believing it was a possible trap, he passed it along for Sasuke to investigate, as space–time ninjutsu was required. Later when Inojin and Shikadai discussed Kawaki's trustworthiness, Inojin noted that Sai seemed to trust Kawaki on a personal front.
Later, after the village was infiltrated and attacked by Jigen, using Kawaki's Kāma as a portal to get in, the village was put on high alert. As Naruto and Sasuke were recovering from a near-death experience against the leader of Kara, the organisation's chief scientist, Amado, appeared. He took Shikadai as a hostage, forcing Sai and a unit to approach him. The man asked to talk with Shikamaru, who was given communication via the Mind Body Transmission Technique. The man stated firmly that he wished to defect to Konoha, offering his full intel on Kara and its resources, their Ten-Tails, and even on the Ōtsutsuki. By order of the Hokage, Amado was brought in for questioning.
While reviewing the terms of Amado's asylum agreement, he raised the likelihood of Isshiki coming to Konoha to apply a new Kāma to Kawaki, so Sasuke was ordered to begin evacuation procedures for the civilians.

- (To himself) "This… is what it means to have friends… I understand it perfectly… Naruto."
