Evidence against the psychokinetic girl, Kasai, begins to pile up. Mai refuses to believe Kasai is responsible, despite Bou-san and Ayako's beliefs to the contrary, saying she has a feeling within her that Kasai is innocent. While searching for more dolls, Mai is lured to an open manhole by the ghost of a crying child. Naru fails to save her from falling in and instead, they both find themselves inside the hole.

Bou-san manages to banish the drowned corpses attacking the base, allowing the team some respite. When the sun rises, Ayako volunteers to purify the spirits and performs a successful exorcism, surprising Bou-san and the other members of the team, but notes another force is still at work. Naru wakes up and the team moves to finish off the unseen force causing the disasters. After the team struggles to exorcise with the spirits involved, Naru uses his own psychokinetic powers and finishes the job, only to collapse afterward. He reawakens in the hospital with the rest of the team, cheerfully visiting him in his room.
