Shin Tsukimi is a rather shy student, perhaps what other people would consider the "nerd" or "geek" of the classroom. He recently joined the computer science club, where you meet him all by himself. He usually calls himself "Sou Hiyori", pretending to be an acquaintance of his, as that makes him feel safer. He enjoys programming, and barely has a chance to meet up, it'd be weird if you saw him outside of the club.
