Makise Ryo, the student president of a catholic school, seems to be liked and admired by everybody, including his cute little brother even if the latter is somehow jealous of his older sibling. When Ryo gets abducted by delinquents from his school who wanted to "teach him a lesson";he's saved by a mysterious student. Gunta didn't help him out of sympathy but "just because they woke him up".

Later, Ryo meets him again and weird things start to happen...

[spoiler]Wyobraźmy sobie katolicką szkołę... opętaną przez demony i dwóch braci. Niezauważany i pomijany młodszy brat, ma już dość! Pragnie zemsty! A jak najlepiej zaszkodzić wzorowemu Przewodniczącemu Samorządu Szkolnego i kogo wziąć do pomocy? Jednak czy ci źli rzeczywiście są źli? Kto za czym się opowiada?
