Sehun is interested in occultism because he's just like that: weird with a tad of creepy!

All night long, he reads books about demonic rituals, creates plans to take over the world and tries to put spells on people - especially his friends who are from hell itself.

He even manages to establish an occultism club at school because his plans are indestructable!

And of course because Sehun secretely runs the school, his test object for his ruling skills that will be needed in the future when he will dominate the whole world.

Everything goes fine and like Sehun has planned it.

Until a certain person appears, that is. 

A person who is just as smart as him and wants the world dominance for himself, starting with the school...
