太川 イチカ

The protagonist's senior. A second year student.

Has many friends, and reigns at the top of the school hierarchy. She is also famous outside of school as a magazine model. She wears her uniform in a sloppy manner, which is her fashion style. Having many male friends, her erotic aura and her excessive skinship has lead people to believe that she loves fooling around, but in reality she never had a single relationship with the opposite sex, let alone a sexual experience. Because of that, she is often teased by her friends for not having a boyfriend.

She started noticing the protagonist during that one uniform inspection case, which is made worse by her friends making fun of her for it. Because the protagonist is a junior, she treats him like a little brother.

Her friend Aoi invited her to become a model, but Aoi retired when she entered high school.

She is a library committee member, and does jobs comparable to a librarian's. She is actually really serious.
