Nikki, a student who is a bit of a loser, is in love with female classmate Akemi Ito, who is herself smitten with the protagonist, Tatsuo Nagumo. After another painful rejection, the lead bully girl comes over to Nikki and invites him to a little get together with herself and several other girls. What he does not realize, however, is that they only want him as a lookout while they engage with one another sexually.
The girls humilate Nikki, mocking the size of his member and one forces him to lick her feet. The abuse eventually comes to an end, however, when several demons appear and murder each of the girls in a gruesome fashion. They then explain to Nikki that he can obtain this kind of power as well, if he does what they say.
