Souta Hosono is a hikikomori, an antisocial boy who spends his school time in the infirmary. He becomes infatuated with a classmate, Kiwako Nitta, stalking her and her boyfriend, Hirohisa Sugita. Souta accesses the Hell website to send Hirohisa to Hell but Ai rejects him because his rage is not strong enough. One day, Souta overhears Hirohisa telling his friend, Sawazaki, that he will "lend" Kiwako to him so that Sawazaki can lose his virginity by raping her. Souta begs Ai to save Kiwako but refuses to sell his soul in exchange; Ai tells him that her service is not for seeking justice. Kiwako is drugged and raped; she later tells Souta that she has sent Hirohisa to Hell for what he did. Souta is shocked that she would agree to go to Hell for that and turns down Ai's help, deciding to kill Sawazaki himself.
