Sousuke is the class president, and is a stickler for the rules. Lately, he's had lots of problems. First of all, he's got to deal with his cute, but unruly, childhood friend Miroku. Secondly, they have a new transfer student, Enma, who claims to be from hell. Enma refuses to follow any rules but his own. Lastly, there's the giant, mysterious claw marks that have been appearing all over school buildings. With all this trouble going on, will Sousuke follow the rules or learn that sometimes there are more important things?
