When a new bath house opens in the crater, Kotomi asks NieA and Mayuko to investigate. Since they can't go inside or they'll be recognized, they enlist Genzo and Chiaki to help get intel from the inside. Outside the new bath house, Mayuko finds some interesting leaves that they are using in the bath house. Suddenly the back door opens and out walks Kaana, the Indian alien, and confronts them as the owner of the new bath house. Mayuko runs off with NieA in tow. Later at the Enohana Bath House, Genzo and Chiaki come back and are acting very strange. The group discover that the strange leaves Mayuko found are an illegal substance and the cops come to shut down the new bath house.
