芦川 ゆきの

A beautiful and smart senpai who is considered the school idol and extremely popular to the point of being confessed to very often. However, because Yukino has no interest in love, she turns down every confession. She is happy for the amount of popularity she has, but at the same time she has no idea why everyone likes her so much.

While Yukino is a student council member, she also secretly helps sometimes at gojoken, but her service there is terrible and awkward. In her previous school, she was part of the same committee Shigeru and shared a bond with him. Because she is helped by Shigure even nowadays, she wants to thank him, so one day, she calls him to the rooftop in order to give him a stapler.
