Lecherous high school boy Hanahei Yamada, called Hanappe for his sexual inexperience, is visited by two demons who come out from his TV (after he accidentally writes "abracadabra" while stroking his...you know) that immediately control his entire family: the rocket launcher-wielding Ophisto Bazooka takes his mother as a bed-buddy, and the furry yet fatal Mephisto Dance conjures all the money his dad can dream of while seducing his sister into sapphic lust. After these two entities of occultic evil have assimilated themselves and all their hellish friends into Hanappe's life, they've granted him only the most corrupting demonic powers any man dreams of...but will this clumsy demigod of a kid be able to handle a fantastic phallic pointer finger, superhuman strength, and the grotesque sexually-tinged situations that await him!?
