Himeko Inaba

is the Vice President of the Student Cultural Society Club and a classmate of Taichi and Iori's. She is exceptionally skilled at gathering and analyzing information and as a result, knows many private details about her fellow club members. Although she is calm and logical, she has a difficult time handling awkward situations and doesn't like things to get out of her control.

Personality
With a short-temper and an intolerance for disorder, Inaba is easily the most volatile member of the Cultural Club. Despite her rough edges, she is generally quite considerate of her fellow members. Inaba always looks out for everyone's best interests, and, though she doesn't like to show it, she greatly treasures her friends and would be willing to sacrifice her own happiness to keep the group together. When dealing with a problem, Inaba typically chooses to take a very direct approach to solve it, making it a challenge for her to deal with delicate situations. Inaba is also a naturally distrustful person and worries constantly about the detrimental effects each phenomenon will have on her and her friends.

Behind her front of arrogance and self-assurance, Inaba has proven to have very low self-esteem. This is largely attributed to her distrustful nature and social awkwardness, imperfections that she acknowledges she has but cannot accept. Also, due to her cold and distrustful nature, it seems that Inaba doesn't socialize with others outside of the StuCS. However, after dating Taichi, she becomes slightly more open, but is also prone to becoming jealous when other girls interact with him. Inaba has noted that since she started dating Taichi, she has begun to overly rely on his strength rather than her own.

Because she is interested in data analysis and logistics, Inaba plans to specialize in science courses and, in the future, attend a university to better understand Heartseed.

Key Problem
Inaba has great difficulty trusting people and, because they hold the power to potentially betray and hurt her, this includes her friends. Rather than coming from some sort of trauma or childhood tragedy, Inaba claims to have been born with this problem and has not been able to trust others her whole life. Despite hating this part of herself, Inaba cannot help but think of others as potential enemies, regardless. This has lead to Inaba having a very poor image of herself and has contributed to her former isolation before joining the StuCS. Over the course of the series, Inaba gradually removes her defensive walls and slowly learns to love and trust her friends unconditionally.

Appearance
Inaba has shoulder-length black hair and brown eyes. Unlike most of the other girls whose uniform sweaters are colored yellow, hers is brown. Inaba has been noted to have good posture, and a slim, yet long figure.

Background History
Skilled in computer use, even knowing how to build computers and use macro programming, Inaba originally joined the Computer Club, however, she left due to an argument with the club's President. As a result, Inaba wounded up helping establish the Student Cultural Society Club, becoming its Vice President only because of winning a rock-paper-scissors game.

Family
Inaba's only family member to appear so far is her older brother, a college student. Inaba and her brother do not get along very well and she prefers to avoid speaking with him. Her brother is known to bring girls home from college.

Friends

 * Yaegashi Taichi: A male classmate and fellow member of the StuCS club who Inaba dubs a "Selfless Freak". Inaba did not care much for Taichi at first, but over the course of the series, she forms a strong bond of trust with him and eventually develops feelings for Taichi. During the Kizu Random arc, Inaba confesses to him but is turned down due to Taichi being in love with Iori. Undeterred, Inaba refuses to give up on him and at the end of the Michi Random arc, the two begin dating. Inaba's love for Taichi later develops to the point where she claims she can't imagine life without him. Additionally, Inaba is willing to do anything Taichi says, even stripping down to her underwear, which was tested by Chihiro pretending to be Taichi using Illusion Projection.

When Iori discovers that Inaba is in love with Taichi, she encourages Inaba to admit her feelings and the two become rivals for Taichi's affections. After Inaba and Taichi begin dating, Iori gives her full support to the couple, making good on her promise to remain friends.
