About

Ino Yamanaka (山中いの, Yamanaka Ino) 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 and she cried when Sasuke was declared an international criminal, showing that she still cares for him despite his descent into darkness. 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.
