Finding a manga

God damn it. I was reading a manga but lost it admist the 'first lady' redirection chaos Mangago experienced. It's called Zankyou something Kyoushitsu or something. It's a horror/psychological-esque manga. They're shorts/snapshots of the unfortunate fates that middle school girls experience in school.

The art style is very uh... kawaii and old school kind of. It has that Shugo-Chara or Vampire Knight feel I think. Basically those big googly anime eyes, something that would make you think of the old school stuff.

The one instance of one of their many shorts was that a girl got some type of console, started playing a game which greatly paralleled choices she made in real life. If she deleted her save game, everything would be lost: including her life. (spoiler not spoiler)

For example, she chose to stop and look at her surroundings instead of walking forward, and in that instance a younger pre-schooler walked in front of her and was instantly ran over by a truck. She started noticing her in game life bar going down.

Later it was announced that a serial killer was loose near the school, and she chose to stay at school on the console game after a contrived fight with her classmate/friend. But this results in isolating her and making her a perfect target of the serial killer, trapping her within the school. Her life bar on the console was almost completely depleted.

Her last ditch method to survive is to delete her save life and quit the game, in hopes of removing the serial killer trying to kill her in real life and her avatar in game. But she ends up being deleted as well, as per the original warning she received starting the game.

Anyone seen it lately? Would love to keep reading it for the gritty, unorthodox horror.
