Nanami is a hostess at "Cutie College," the cabaret club where Kapaeru works part-time to collect information. There she is working hard for her boyfriend Sabu, though she herself never feels comfortable doing this job. On her birthday, Nanami gets a Japanese doll from Sabu as a present. Nanami, whose hobby is collecting dolls, becomes ecstatic. More than anything, the fact that it's from Sabu is the reason why she always takes it with her to the club she works at. However, one night, when she returns home from work earlier than usual, Nanami catches Sabu cheating. It was after that day that mysterious murders started happening to Nanami's acquaintances...

Appearances of demons decrease day by day and Enma and others enjoy rather peaceful days. Kapaeru has a mail-friend named "Sat-chan." Being a young little girl, she has a sort of adoration towards Kapaeru. He gives her advice, and she calls him "Kapa-chan." One day, Kaperu receives an E-mail from Sat-chan, saying "I want to meet you." However, Kapaeru worries that his monstrous appearance would disappoint her and asks Enma to see her pretending to be her "Kapa-chan." Her problem is a serious one: It seems she has been abused by her parents. Later, after receiving an E-mail from Sat-chan asking him for help, Enma and Kapaeru rush to the site. Meanwhile, an abnormal incident happens to Yukihime.
