shin and umeji are dating. Shin is in a deliquent club and umeji is in a occult club, even if umeji is in a occult club, shin would never AND I MEAN NEVER will break up with him.

Umeji is mostly quiet, he stays in the library or the occult room. Shin is a trouble maker. He and his deliquent friends have different weapons on their backs. For example touya one of the deliquents have a crowbar on his back.

One day, shin and his deliquent friends were messing around with some chemicals. Suddenly, one of the potions went wrong and they've turned into crazy looking people with distorted and creepy smiles. They go around and infect the student's, umeji is reading a book as usual. Having no idea of anything going around.
