Ten days have passed since the incident with the heroes. Yuki tells Basara that she will live with them to monitor Mio, and Maria offers Yuki to accept a Master/Servant pact with Basara the next full moon. On the day of the full moon, the girls are in swim class and Basara sees Maria running around the school. He finds her and is led to all sorts of places (the girls rest room and the roof where a couple are having sex). When they end up in the changing room, Maria finds Mio's locker and puts her panties on Basara's head. Before he can take them off, the girls return from swim class forcing the pair to hide in Mio's locker and for Maria to trick Basara. When Mio finds them, she attacks them in the locker but understands that they are only there for her safety. This sets off the curse, which Basara makes her submit using the shower head - increasing their powers. Maria meets Lars for some needed information. In the Demon realm the Zolgia watches the fight and Mio's development, he stages another plan to capture her.
