2x4 - Hell Girl

Yagisawa's wife, Chinami, is in the hospital, fighting an illness. He'll do anything for money to help her. He enters the site to get revenge on Hhouki, the man who tricked him into killing a man for money. Hhouki wanders into the hospital and tells Chinami that her husband killed a man, causing her to go into a coma due to her distress. He eventually send Hhouki hell (for refusing to help his wife and blackmailing him). When he returns to the hospital to tell his wife that everything is okay, she no longer remembers him. Kikuri is seen wandering around the hospital and having a strange effect on Chinami. In this episode, she leaves the mortal world with Ai and officially becomes part of the group.
