Shokuryou Kyoushitsu
A horror manga where an evil creature is stalking students in a classroom and eating them.
I’ve read multiple manga about a students turning to fear and hysteria over an unknown killer within their group so the basic premise for this series wasn’t anything special. However the artwork on this one is really good. The creature has a horrific design and the violence and gore are very disturbing right from the beginning. I ended up checking out all 3 volumes mostly based on the strength of artist Renji Kuriyama.
If you’re a fan of horror then this one might be worth your time.
