Chapter 1: Tsukigami High

When a young girl named Aoi Nakano, finds out that her brother, Aka Nakano went missing after an incident, she then encounters a butterfly that sends her mysterious messages everyday.

However, she doesn't know who the sender is. It could be the thotty bad girl, Kim Murasakino, or the school delinquent, Kuro Taiyō.

Or it could be someone else she never thought it would be.

What if the student body goes out of control to the point where the student council can't do anything?

Will any of the problems that happen be resolved?
