After awaking in Tsugumi’s health office, Yuzuki asks her about Ai Enma but Tsugumi refuses to give her a clear answer. Later, Yamawaro and Kikuri approach a large mansion belonging to a client but are unable to enter due to an encircling barrier. At night, the owner of that mansion, Mizuragi Shōgo, accesses the Hell Correspondence website and types Tsugumi's name in. Each sensing the request, Yuzuki, Ai, and Tsugumi make their ways towards the mansion. Once they gather, he explains that he initially gained interest in Hell after his mother used Ai's services to send his father to Hell. After a great deal of research on Hell, he yearned to meet Ai. Learning that she had once more regained her body, he nurtured a grudge against Tsugumi through hypnosis in order to meet Ai. Ai agrees to give him Ren as a doll, however just before Shogo can completely pull off the string, he is instead sent to Hell by his assistant Kikyō using Yamawaro due to the grudge that the many children bore whom Shōgo treated cruelly for the sake of his research.
