Ino Yamanaka

is a secondary character in Naruto who is on Team 10 with Choji Akimichi and Shikamaru Nara, under the leadership of Asuma Sarutobi.

Background
Ino has known Sakura since the two were very young, and was a considerably more popular and self-confident girl than her at the time they met. 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. When Sakura became attracted to Sasuke, and found out that Ino was attracted to him as well, Sakura ended their friendship so they could properly compete for his affection. Ino later made friends with Sakura again during the Chunin exam, but they are still considered rivals by many, including Asuma.

Personality
Ino is somewhat superficial, constantly thinking about boys and hoping by dieting to lose weight will make her be more attractive to them. Ino can also be very confident, and outspoken, and isn't afraid to speak her mind and sometimes suggests that Choji should lose weight, but in the filler arcs, she explains that his fat is essential for his techniques. 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.

In her team, Ino tends to boss the others around. 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 recognizes the control she has over the others, and while dying, tells her to look after Choji and Shikamaru and ensure that they do not get into trouble and don't let Sakura surpass her.

Despite her superficial bossy persona, Ino has a soft side to her, and is capable of being compassionate at times. She develops a strong bond with her teammates which grows greatly when the trio are faced with the loss of their teacher.

Ino has shown to possess a good level of intelligence, in the Konoha 11 filler arc, she was able to figure out that the Academy is the location of where Genno planted the explosive, sharp enough to figure out that Asuma was seeing Kurenai, has the uncanny ability to be able to tell a person's occupation by the condition of their hands, and manages to learn medical ninjutsu which is no easy feat.

Chunin Exams
In the anime, Ino plays a small role in Episode 3, being upset when she does not get onto Sasuke's team while Sakura does, and being dismayed to be on the same team as Shikamaru and Choji.

Ino later reappears in the Chunin Exam. She uses her Mind into Body (or mind transfer) technique to enter Sakura's mind and memorize all her test answers, then sends her mind into Choji and Shikamaru's minds to give them the answers. In the Forest of Death, she helps Sakura and Rock Lee fight off the Sound Genin until Sasuke, his Cursed Seal having awoken, forces the Sound Genin to retreat.

Ino's first match in the Chunin Exams is against Sakura. The two do not battle seriously at first, until Sakura, unwilling to have Ino pity her, denounces her. Ino and Sakura battle seriously afterward and use up most of their energy in the process. Ino then attempts to enter Sakura's mind after cutting her hair and sending chakra into it to immobilize her. She succeeds, but is expelled by Inner Sakura (after encouragement from Naruto). Low on chakra, Ino and Sakura charge each other for one last attack, and knock each other out, resulting in both of them being eliminated. When they regain consciousness, they start becoming friends again, but still maintain their rivalry over Sasuke.

Ino accompanies Sakura to visit Sasuke in the month between the preliminaries and the finals, but finds that he is gone. She goes to the finals with Sakura, and notes that Sakura's team is extraordinary after seeing Naruto defeat Neji. When the invasion starts, she is rendered unconscious by Kabuto's genjutsu; Sakura briefly considers waking her to help pursue Sasuke, but Kakashi tells her that a group of more than four people (herself, Naruto, Shikamaru, and Pakkun) would not move effectively.

Filler arcs
In the filler arcs, Ino accompanies Naruto, Shino and Anko to the Land of the Sea, and helps defeat Misumi Tsurugi by possessing him and tying his arms to pillars, leaving him trapped in a collapsing room. Ino then uses Mind-Body Break (or Mind Destruction) Technique on Yoroi as he attempts to attack Shino, allowing Shino to punch Yoroi away. When Yoroi attempts to attack Ino, Shino sends his bugs after him, defeating him.

She later appears in a mission with Naruto, in which she tries to replace a princess who has grown overweight in an attempt to woo her suitor. Ino is barely able to stand the man, but the mission succeeds after Naruto, while interfering, accidentally exposes the real princess, during this Ino briefly reveals an "Inner Ino" similar to Sakura's "Inner Sakura".

In the Konoha 11 arc, Ino and Sakura are sent to examine a corpse that is believed to be that of Genno. Ino hesitates, but eventually enters the room, and concludes from the condition of the hands that the corpse was not a ninja or a carpenter, and that Genno is still alive. After the group finds Genno, she attempts to possess him when he tries to make his escape on a summoned bird; while he lets go of the bird, Ino is unable to maintain the technique, as she notes that he has been suffering terrible pain the entire time. Genno dies shortly after his plans are foiled, possibly from what had caused that pain.

In the Shitenshounin arc, Ino accompanies Shikamaru to help rescue Temari. Her attempt at possessing their opponent Kyaku fails, leaving her at risk. Kyaku later is defeated by Shikamaru and Temari's combined efforts. Feeling guilty that she did not contribute much to the mission, she asks Sakura to ask Tsunade to add her as a second apprentice. Sakura agrees, but adds that she will be Ino's senior apprentice (leading to yet another fight).

Sasuke and Sai arc
Ino made her first reappearance shortly after Team Kakashi and Team Guy return from the successful saving of Gaara. She appears shortly after Sai attacks Naruto along with Shikamaru and Choji to test Naruto's skill level. After the failed attempt to retrieve Sasuke, Ino appears again with Team Asuma to visit Kakashi in the hospital. While oblivious of what happened, she was pleased to see Naruto again and cheerfully said hello.

After the failed attempt to retrieve Sasuke, Ino appears again with Team Asuma to visit Kakashi in the hospital. Quickly, she becomes infatuated with Sai, noted that his looks and attitude reminds her of Sasuke. Later while eating a meal with Team Kakashi, minus its captain, Ino attempts to get close to Sai with some casual flirting. Sai, attempting to make friends with his new acquaintances, tries to use what he learned from his books by kindly calling Ino "Beautiful". This resulted in Ino blushing madly and Sakura going into a fit of rage from Sai treating her poorer by calling her "Ugly".

Fire Temple Filler arc
When word of villages on the border of the Fire Country have been attack, Ino, along with the rest of Team Asuma, go to investigate. Later, during the attack on Konoha, Ino does her part in the resistance by performing her duties as a medical ninja. As Naruto tries to calm Sora, he talks about his friends an the Kyuubi. It is assumed that the Konoha 11 know about him being the container of the Kyuubi.

Hidan and Kakuzu arc
When Tsunade decides to make a move against the Akatsuki, Ino is assigned along with Choji, to a Niju Shotai team lead by Aoba Yamashiro and Raido Namiashi. Ino and Choji arrive as backup for Shikamaru and Asuma in their fight with Akatsuki members Hidan and Kakuzu.

As the Akatsuki pair leaves due to being called back by Pain, Ino tries to use medical ninjutsu to heal Asuma's injuries, though she knows that there's nothing she can do to save her sensei. Asuma, also knowing that he won't make it, gives some parting words to his team. To Ino, Asuma says that her spirit is strong and that she is a helpful child, so she should take care of Choji and Shikamaru. Asuma also tells Ino not to lose to Sakura in ninjutsu or in love, to which Ino agrees. After smoking one last cigarette, Asuma dies.

Shikamaru, Ino, and Choji all agree to avenge Asuma. Under the guidance of Kakashi, Team 10 later sets out to face Kakuzu and Hidan. By using her Mind Body Switch Technique on a hawk, Ino is quickly able to find the Akatsuki duo so Shikamaru's plan can begin. During Team 10's fight with Hidan and Kakuzu, Ino plays the role of an observer, her Mind Body Switch Technique being too much of a risk to use in battle. The anime though expands on Ino's role. As Choji is about to be killed by Kakuzu, Ino throws a shuriken which proves enough to distract Kakuzu so Shikamaru can attack. She is quickly grabbed by Kakuzu and nearly has the life choked out of her, until Shikamaru saves both her and Choji. She later heals Naruto after he defeats Kakuzu.

Pain's Invasion
When Pain begins his invasion, she along with Choji, Kiba, Shino, and Hinata saw the devestation. She then ran into the interrogation chamber to warn her father. Later, she along with Shizune, her father, and Ibiki are attacked by Animal Path Pain with Human Path at the interrogation chamber. Shizune, Inoichi, and Ino leave Pain's bodies to Ibiki so that they can figure out the truth about Pain with Inoichi's new information. Ino, her father, and Shizune then move to the code deciphering office.

Abilities
Ino is considered one of the more talented kunoichi in the academy, shown by how she excelled in kunoichi infiltration training. She is fairly skilled in most ninja arts. She primarily uses mind-affecting jutsu, such as the Mind Body Switch Technique, a jutsu used for reconnaissance also a jutsu that is a coming of age jutsu for the Yamanaka clan, which allows her to possess someone and control that person's actions for about two to three minutes. However, her body feels any pain that the target feels while possessed, and she will die if the target dies. Missing results in her being unconscious for several minutes while her mind returns to her body, leaving her extremely vulnerable. The anime takes her skills a bit further by giving her the Mind Body Disturbance Technique, which causes the person effected to lose control of their body. As long as Ino can hold the hand seal and the amount of chakra she has is how long the technique lasts. By Part II, Ino has become a Chunin and medical ninja. Ino has been considered rather capable in medical ninjutsu. During Pain's invasion, her father communicates to Ino using telepathy. This skill may be a part of Ino's arsenal of abilities. Back when they were younger, Sakura and Ino were compared often in ninja skills, and while Ino is fierce, Sakura proved to be the better ninja of the two, which only drives Ino to become better for herself and for Asuma.

Games
Ino is the recipient of a very powerful move-set in the majority of the Naruto fighting games being considered one of the top tier characters, mistakenly or otherwise, due to her powerful kick combos with a low block rate, setups, aerial combos and insanely powerful drill kick combos, making her vastly superior to certain characters. In some games, she is known to use a purple flower called Ninja Wolfsbane which generally poisons her targets and other moves related to flowers. And in newer games she has shown to have a nack for genjutsu.
