Pretty good except I think the revenge for  Yoarashi  story feels a little tacked on after spending 4 volumes on the teacher bullying story.
Wouldn't  Hanada  try to get revenge for yoarashi straight away instead of spending months helping the teacher?
I guess you could say that she wanted to try and find the ringleader, but still it feels a bit strange.
Also, wouldn;t hanada want  to get revenge on Saiki after she got out of prison? I mean  she'll get ouot age 26 and be able to live a happy life and have a family , while Yoarashi will never be able to.
but still I liked it.
this guy's mangas are always a good read just because the art and  execution/storyboarding are good.
