Himeko is the vice president of the cultural club, who has a contrasting personality with Iori. She often reacts violently to Taichi or Yoshifumi's jokes, and is nicknamed "Inaban" by Iori. She was a computer club member but quit after having an argument with the president of that club, and then joined the cultural club. She is generally distrustful of others and worries a lot, even more so when they begin swapping bodies. Between them, she is the most calm and rational when dealing with unexpected situations. During Kizu Random, Heartseed confronts her in coming to the realization that she has feelings for Taichi when she was pretending she didn't know. She confesses to him after the class trip by the encouragement of Iori, declaring that she would make him fall for her even if he was in love with Iori. Over the course of the series, she gets more and more attached to the group, especially Taichi, and softens her sharp and rational personality.
