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, always looking out for everyone's best interests, and though she doesn't like to show it, Inaba 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.

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
Inaba originally joined the Computer Club, however, she left due to an argument with the club's president. As a result, Inaba wound up helping establish the Student Cultural Society Club, becoming its Vice President.

Family
Inaba's only family member to appear so far is her older brother, a college student, who notes that Inaba typically leaves home without saying a word. Inaba and her brother do not get along very well. 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, Inaba and Taichi begin dating.
 * Nagase Iori: A female classmate and the President of the StuCS club. Despite being total opposites of each other, Inaba considers Iori one of her closest friends and knows a lot about Iori's personal issues. 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.
 * Aoki Yoshifumi: A male StuCS club member. Inaba often punishes him for his silly antics and has little patience for his pervertedness. Even though she gives him a hard time, at the end of the day, Inaba considers Aoki a good friend.
 * Kiriyama Yui: A female StuCS club member. The two have been shown to be good friends, and Yui even helped Inaba prepare her Valentine chocolates. Inaba also knew about Yui's androphobia before anyone else.
 * Fujishima Maiko: Inaba’s class representative. The two will sometimes conspire together to reach their own devious ends.

Others
Due to her cold and distrustful nature, it seems that Inaba doesn't socialize with others outside of the StuCS but this changes after dating Taichi but still continues to be jealous of other girls getting near him.

Trivia
