Shokuryou Jinrui Re

The usual school, the usual classroom, the usual classmates...but something seems a bit off... When a boy realizes the source of his anxiety, he finally puts it to words. "I'm scared to die." The moment he opened his mouth and the sounds escaped his throat, a blood-filled hell has been unleashed as it slowly seeps out...
