Taciturn But Absurdly Enthusiastic Black Cat–chan

Kuroi-san, the girl sitting next to me, seems like a quiet type, but she's actually a fun-loving black cat!

Our main guy, Akama, is trying to make a good impression at high school, but his efforts to be popular keep falling flat. Kuroi, the cat girl who always looks at him coldly, is actually pretty easygoing and happily accepts his invites, which lifts the mood for him and his classmates.
