Hello everyone,
I am looking for one particular manga with lot of chapters I have read years ago and totally forgot the title (and cant find it through horror tags) that still lingers in my head.
So it was kinda compilation of some (high) school ghosts-evils, no funny moments, seriously dark and twisted. Each story was revolving around school doll visiting dying children you follow through their story and making them into school ghosts.
The first arc was about bullied little girl who was picked on by classmates and bullied by teacher too, he was torturing her on some abbandoned toilets if I recall correctly, she threatened to tell on him, he murdered her and she became a toilet ghost sort of... then he found out about her being a ghost and mocked her and tortured her again for being a lame ghost. The rest of the stories had very similar unpleasant vibe..
Any suggestions? I think the name somehow reflected Seven ghosts/evils of highschool or something along those lines.

Count yourself lucky I always remember things that I hate. Have fun, though I'm not sure if it has been completely fan-translated in English.
