Masako requests Naru to investigate a park where couples have had water dumped over them from thin air, which has been happening for over a period of six months. The team, excluding Lin, split up at Masako's suggestion into pairs and they soon attract the spirit of a woman.

Mai convinces her to let go and move on to heaven, but not until they have forced the cheating partner to acknowledge the hurt he had caused her.
