Ino Yamanaka

is one of the main supporting characters of the series. She is a chūnin-level kunoichi of Konohagakure's Yamanaka clan and a member of Team Asuma. Along with her team-mates, Ino makes up the new generation of Ino-Shika-Chō, just like their fathers were before them.

Background
Ino was a considerably more popular and self-confident girl than Sakura when they met at the Ninja Academy. She convinced Sakura that hiding the size of her forehead was pointless, and gave her a ribbon to draw attention elsewhere, suggesting that Sakura had great potential, but had yet to reach it. She helped Sakura gain her confidence. When Sakura became attracted to Sasuke, and found out that Ino was attracted to him as well, Sakura ended their friendship hurting Ino in the process so she could compete with Ino for his affection. Ino later made friends with Sakura again during the Chūnin Exams, but they are still considered rivals by many.

Personality
Ino is constantly thinking about boys and hopes that dieting to lose weight will make her more attractive to them. Ino can also be very confident, kind, and outspoken, not afraid to speak her mind, and sometimes suggests that Chōji should lose weight. She is attracted to Sasuke, but her reasons for that attraction, apart from Sasuke being a popular student and the best in his class, are unknown. She is described as relatively cheerful.

In her team, Ino tends to boss the others around, though she clearly cares for them, as shown by her relief when Chōji survived near fatal injuries. Shikamaru, despite thinking of most girls as "troublesome", typically offers no resistance, being unwilling to deal with how she reacts if she is unable to have her way. Asuma recognized the control she has over the others, and, while dying, told her to look after Chōji and Shikamaru, and ensure that they didn't get into trouble.

Ino has shown to possess a great level of intelligence and perception; this was proven when she was in the Chūnin Exams and cleverly used her hair to make a chakra rope to bind Sakura, also a fact that she was the top graduating in the academy tied with Sasuke and Shino, and in the Konoha 11 filler arc, she was able to tell a person's occupation by glancing at the condition of their hands. Also, during Pain's invasion, she was able to conclude that Pain's real body must be around the village for his technique to work, since it was similar to her clan's.

Appearance
While always in a rivalry against Sakura to prove who is the better kunoichi, Ino takes most pride in her appearance, which was seen even during her younger days in kunoichi training. She also takes great effort to keep up and improve her appearance, as seen from her habit on dieting. The most noticeable traits in her appearance are her green eyes (blue in the anime) and her long blonde hair, always seen in a ponytail with bangs covering the right side of her face. In the beginning of Part I, her hair reached down to her waist, she cut her hair during her fight with Sakura, and after, she wore a bun. After Shikamaru's promotion to Chūnin and also during the anime filler, she wore her hair down to her neck as it lengthened.

In terms of attire, Ino is more often seen wearing purple, and more revealing, clothing, seemingly to show off her figure. During Part I, she wore a short purple vest like shirt with a raised collar, a skirt that was cut off on the sides and bandage on her stomach and legs. She also wore purple and white elbow warmers with this, and her headband around her waist as a belt. During the anime filler, she stopped wearing the elbow warmers. In Part II, Ino also removes the bandages around her waist allowing her stomach to be seen and replaces the warmers on her elbows with fishnet and also wears fishnet over her knees. She wears a short purple shirt, an opened purple skirt and a black skirt underneath. However she is no longer seen wearing her headband. She also wears a red clip in her hair. She is also equipped with a Chūnin's tantō, which she wears above her medical pouch, but has never been seen using it. Apart from that, she also wears simple earrings, which is identical to Chōji's and Shikamaru's earrings. The earrings are given by Asuma after Chōji and Ino passed the Chūnin exams.

During the Fourth Shinobi World War, she wears the standard uniform of the Alliance and a Konohagakure flak jacket.

Abilities
In Part I, Ino is noted to be similar in skill to Sakura. During their fight in the Chūnin Exams, she was able to turn the battle in her favor through the simple act of cutting her hair, overcoming her jutsu's inherit weakness and mimicking the Shadow Imitation Technique at once. For this reason, Sakura notes that Ino probably would have beaten her had Naruto not interfered.

Ino has also displayed sensor-like abilities in the past. Seeing as how all known members of her clan are sensors, it is likely she is one as well.

Yamanaka Clan Techniques
Ino excels in the techniques of her clan, which are primarily focused around mind-affecting techniques such as the Mind Body Switch Technique, a jutsu used for reconnaissance, that allows the user to briefly possess someone and control that person's actions. Her body is left vulnerable until she returns. Despite many people thinking that this technique is unbeatable, she can still be forced out of the body if her opponent is physically very strong or has a strong enough will. She can even use the technique on animals, such as hawk to act as a spy. This jutsu was originally invented as a spying technique. The anime takes her skills a bit further by giving her the Mind Body Disturbance Technique, which causes the body of the person affected to attack those nearest to them, or immobilizing their body.

In Part II, her timing with the Mind Body Switch Technique has improved to a point that she only needs a target to be briefly immobilized in order to invade their mind.

Medical Ninjutsu
Ino learned medical ninjutsu during the gap in time between Parts I and II. A flashback scene during the Three-Tails filler arc shows that Ino trained in medical ninjutsu alongside Sakura under Tsunade's supervision. Ino has proven to be skilled enough to be able to tell the severity of an attack with just a glance. With the knowledge of plants and flowers she gained in her family's flower shop, she also has the capability to create herbal medicines. She has also gained better chakra control because of her study in medical techniques.

Chūnin Exam Arc
Though making a few brief appearances earlier in the series, Ino made her debut during the Chūnin Exams. She used her Mind Body Switch Technique to enter Sakura's mind and memorize all her test answers, then sent her mind into Chōji and Shikamaru's minds to give them the answers. In the Forest of Death, Ino had many flashbacks of her childhood when they saw Sakura was in danger, she and her team helped Sakura and Rock Lee fight off the Sound Genin, until Sasuke forced the Sound Genin to retreat.

Ino's first match in the Chūnin Exams was against Sakura. The two did not battle seriously at first since Ino still cared about Sakura, until Sakura, unwilling to have Ino pity her, denounced her even though she didn't want to hurt Sakura. Ino and Sakura battled seriously afterwards, and used up most of their energy in the process. Ino then attempted to enter Sakura's mind after cutting her hair and sending chakra into it to immobilize her. She succeeded, but was expelled by Inner Sakura. Low on chakra, Ino and Sakura charged at each other for one last attack, and knocked each other out, resulting in both of them being eliminated. When they regained consciousness, they started becoming friends again, but still maintained their rivalry over Sasuke.

Ino accompanied Sakura to visit Sasuke in the month between the preliminaries and the finals, but found that he was gone. She went to the finals with Sakura, and noted that Sakura's team was extraordinary, after seeing Naruto defeat Neji. When the invasion started, she was rendered unconscious by Kabuto's genjutsu.

Anime filler arcs
She later appeared in a mission with Naruto, in which she tried to replace Princess Fuku who had grown overweight in an attempt to woo her suitor Chikara, the daimyō of The Land of Noodles. Ino was barely able to stand the man, but the mission succeeded after Naruto accidentally exposed the real princess. Ino briefly revealed an due to her anger, similar to  Sakura's "Inner Sakura", during this episode.

In episode 158, academy students were divided into teams of three and were assigned to a genin who would lead them on a mission against the other teams. Ino was assigned to lead a team of three academy students: Sou, Kiri and Shimo. Her time with them was not covered much except that she was doing better than Naruto.

Mizuki Strikes Back Arc
In the anime, Ino along with her team-mates saved Naruto from the Legendary Stupid Brothers and took over the battle so Naruto could aid Iruka. Soon they realised they couldn't defeat them, but they were able to resist until Tsunade showed up and defeated them both easily.

Land of Sea Arc
She later accompanied Naruto, Shino and Anko to the Land of the Sea, and helped defeat Misumi Tsurugi, by possessing him and tying his arms to pillars, leaving him trapped in a collapsing room. Ino then used Mind Body Disturbance Technique on Yoroi as he attempted to attack Shino, allowing Shino to punch Yoroi away. When Yoroi attempted to attack Ino, Shino sent his bugs after him, thus defeating him.

Trap Master Arc
Ino and Sakura were sent to examine a corpse that was believed to be that of Gennō. Ino hesitated, but eventually entered the room, and concluded, from the condition of the hands, that the corpse was not a ninja or a carpenter, and that Gennō was still alive. After the group found Gennō, she attempted to possess him when he tried to make his escape on a summoned bird; while he let go of the bird, Ino was unable to maintain the technique, as she noted that he had been suffering terrible pain the entire time.

Ultimate Weapon Arc
Ino accompanied Shikamaru to help rescue Temari. Her attempt at possessing their opponent, Kujaku, failed, leaving her at risk. Kujaku later was defeated by Shikamaru and Temari's combined efforts. Feeling guilty that she did not contribute much to the mission, she asked Sakura to ask Tsunade to add her as a second apprentice. Sakura agreed, but added that she would be Ino's senior apprentice, resulting in Ino refusing (which led to yet another fight).

Sasuke and Sai Arc
Ino made her first reappearance shortly after Team Kakashi and Team Guy returned from the successful saving of Gaara. She appeared again after Naruto and his team returned from their failed attempt to retrieve Sasuke. Upon meeting Sai, she quickly became interested in him, also noting that he resembled Sasuke.

When they all went out to dinner, Ino attempted to get Sai's attention with some subtle flirting. When Sai tried to befriend Ino and Chōji, having earlier come to the conclusion that women (specifically Sakura), didn't like to hear how they really looked, Sai tried the opposite approach by calling Ino "gorgeous", of which is the opposite of what he wanted to say. This resulted in Ino blushing, and enraging Sakura, who Sai had previously called "ugly".

Twelve Guardian Ninja Arc
In the anime, Ino made her next appearance while selling flowers to Asuma at her family's shop, teasing Asuma about his gift obviously being for Kurenai. When word came that villages on the border of the Land of Fire were being attacked, Ino, along with the rest of Team Asuma and some ninjas went to investigate. Later, during the attack on Konoha, where a horde of ninja zombies appeared, Ino did her part in the resistance by performing her duties as a medical ninja. After the jutsu that brought the zombies were dispelled, Ino together with her team-mates went to the location where Sora was manifesting the Nine-Tailed Demon Fox's power. After Chōji's defeat, Shikamaru ordered Ino to take over Sora's mind and stop him. As she entered Sora's mind, she was threatened by the Nine-Tails' chakra within him and she was told that Sora was already consumed by the monster. Ino's failure then brought her back to her own body. The Nine-Tails then attacked them but Yamato was able to shield them. Ino then tried to heal Chōji's hands but she failed since wounds caused by the Nine-Tails' chakra could not have easily been healed even by medical jutsu.

Hidan and Kakuzu Arc
When Tsunade decided to make a move against Akatsuki, Ino was assigned, along with Chōji, to a Nijū Shōtai team, led by Raidō Namiashi and Aoba Yamashiro. Ino and Chōji arrived as back-up for Shikamaru and Asuma in their fight with Akatsuki members Hidan and Kakuzu. When the duo retreated, Ino tried to tend to Asuma's injuries, but the damage to his body was beyond repair. The team then had nothing to do but listen to Asuma's last words. Before dying, Asuma said that Ino is strong-willed and a reliable child, so she should take care of Chōji and Shikamaru. Asuma also told Ino not to lose to Sakura in ninjutsu or romance. Ino then reminisces about her memories with Asuma especially her first days with him as a student, and when she noticed that the bouquet of flowers that Asuma bought were for Kurenai. After the death of her sensei, Ino screamed out loud with grief.

Shikamaru, Ino, and Chōji all agreed to avenge Asuma. Under the guidance of Kakashi, Team 10 later set out to face Kakuzu and Hidan. By using her Mind Body Switch Technique on a hawk, Ino was able to quickly find the Akatsuki duo so Shikamaru's plan could begin but doing this nearly backfired after Kakuzu attacked the hawk forcing her to return. During Team 10's fight with Hidan and Kakuzu, Ino largely played the role of an observer, her Mind Body Switch Technique being too much of a risk to use in battle stated by Shikamaru. In the anime, she temporarily saved Chōji from a fatal blow by Kakuzu before getting captured by him and almost choked to death along with Chōji, but was saved by Kakashi and Shikamaru. After Naruto arrived and defeated Kakuzu, she healed him.

Three-Tails Arc
In the anime, keeping true to her promise, Ino was seen taking part in a serious operation, and was praised for her efforts by a more experienced medical-nin. Ino was later teamed with Rock Lee and Tenten as back-up for Kakashi's team. Her mission would be using her fine-tuned chakra control to assist in the sealing of the recently discovered Three-Tailed Beast.

After arriving, and having another argument with Sakura, she was put under Shizune's command to directly help seal the beast. While initially having some difficulty handling the technique, her refusal to be outdone by Sakura pushed her to keep her composure.

Unfortunately, the enemies were able to break the seal. Upon the Three-Tails' emergence, Ino was knocked unconscious and rescued by Lee. After recovering, Ino admitted to how useless she felt, swearing to make up for it. She then joined Sakura in healing the young boy, Yūkimaru, that was being used by Orochimaru's men.

After learning that Naruto was trapped in the belly of the Three-Tails, Ino joined the team in another attempt to save Naruto and seal the Three-Tails. The attempt ended in failure, and Ino was knocked out again. Later, they return to Konoha with the others.

Invasion of Pain Arc
When Pain began his invasion, Ino rushed to her father's location to inform him and all those present of the attack. Having learned something about Pain's identity, they tried to escape, to avoid capture. Despite their attempt, Pain arrived and captured Shizune, finding out what she knew, before killing her. After he destroyed the village, Ino tried to revive Shizune, but could do nothing to help her, and regrouped with her father and the others. After the death of Nagato, she was shocked to see that Shizune was brought back to life. She was then present at Naruto's return, and celebrated with the villagers for his victory. In the anime, she even says that she could almost fall for Naruto, surprising Chōji and Shikamaru.

Konoha History Arc
Ino, Sakura and Naruto are sent in Jofuku Forest to deliver a message to Furofoki. On the way there, they were petrified because an old lady from the village's inn said that the place was haunted. Naruto managed to take a sample of Jofuku flower for Lee's special medicine, which he accidentally drank. They then fought a deity representing Gaara, but Naruto managed to defeat it. They arrived at Furofoki's house and completed their mission.

Team Asuma, along with Team Kakashi, go off on a mission where they must save a headman's granddaughter from a gang boss named Baji. During a hostage exchange between Shikamaru and a man named Tōfu, she switches bodies with Shikamaru in order to find out where Baji is keeping the little girl. When Shikamaru is taken to where the girl is, she releases her technique and heads along with Chōji to the location of the two. When the three team-mates are reunited, they quickly apprehend Baji and save the girl, completing their mission.

Five Kage Summit Arc
When news of Sasuke's affiliation with Akatsuki reaches Konoha, the Konoha 11 gather to discuss what should be done with him. The others suggest that they should personally eliminate Sasuke to prevent him from implicating Konoha in a war with another village. Ino is upset by this and she starts crying. Kiba demanded she stop, but she was defended by Tenten. Ino was later seen with the rest of the Konoha 11, hearing Naruto's decision about Sasuke.

Shinobi World War Arc
Within the Joint Shinobi Army, Ino was placed on the Fifth Division alongside Shino, Kiba and Hana which is led by Mifune. She is seen reassuring Shino that he will be fine, after he tells his team that they need to avoid being seen.

Ino later on joined Darui's forces along with Shikamaru and Chōji. She used her Mind Body Switch Technique to transfer her consciousness into Kinkaku's body, stopping him from killing Shikamaru. When Darui called Kinkaku's name, she forced him to respond, activating Kohaku no Jōhei's ability and sucking him within. Ino then left his body, leaving him to be sucked in and sealed on his own.

Naruto Shippūden 3: Inheritors of the Will of Fire
Ino was first seen when they celebrated for Naruto and Sai's recovery and ate barbecue. Ino was seen again when Hiruko appeared on the sky and said he was starting the 4th Ninja War. Later, Ino was sent with the rest of Konoha 11 to retrieve back Naruto and Sakura. Ino's team caught up with Naruto and Sakura, but Sai came and took the two with him to catch up with Kakashi. They were left behind to take down Hiruko 's henchmen, San. They used Ino-Shika-Chō combination and easily took down the enemy. Shikamaru had Ino tell San that they aren't here to fight but to bring back Naruto and the others, after Ino used Mind Body Switch Technique and told San, he refused and said that he understands but he can't just pass the information on, forcing Team 10 to fight him. He then summoned his two team-mates, Ichi and Ni, and used Chimera Technique, which made them turn into a beast, Team 10 was defeated quickly. The rest of Konoha 11 comes to back up Team 10 and while Tenten summoned out chains everyone grabs onto one and as Shikamaru was about to use a jutsu to bind the beast Ino urges Shikamaru to go on and that the rest of them can handle it. Ino is later seen at Hiruko's temple saving Sakura from a collapsing building while the other members of the Konoha 11 defeated the beast.
