Looking for a Manga - title looks like "Syndrom 97"
First of all happy new year !
I was thinking about a Manga I discovered in a Book Shop 2 years ago, but I never had the chance to see it again. Back then It was just released in France. The title was something like "Syndrome 97" or 87... something like that. It's a little bit in the drama/criminal investigation type. Very intense too.
Here are a few details on the beginning of the story.
Basically the story was about a University Student who was a "no-life". He stayed home all day, basically never took his trash out... Anyway once he decided to go out and noticed a group of girls that were harassing another girl. She was like their slave. And The main character became interested in them... anyway to cut a long story short, he ends up killing the leader of the group and the girl who was harassed by her, even if in the beginning he was supposed to help her. And since then he was on the run... that's basically when I stopped reading.
Can anyone help me find the exact title? Every time I try to google it I only find "Sakuranbo Syndrome" and that's definitely not it !
Thank you for your time.
