I'm searching for hours and hours a manga that I read long time ago, but I don't success to find it.
What I remember :
- at the beginning of the story, the action taked place in high school, and the high school was in japanese countryside
- there was superpowers or sci fi cause at least one of the pupils had powers, and I think it was not a good thing for the authority
- there was something with a butterfly (power, weapon, aesthetic...)
- it was very well drawn
I read the first chapters in summer 2014-2015, so it's a recent manga but not too recent.
Thanks very much to all people that will help me
Oh and sorry for the bad english, I'm French.
