Shall I Show Restraint? - S1.E10

Chizuru and Kouta treat Ai and Ren to a meal. Seeing as the two are poor, this has magnanimous effects on them and they regret the whole potion situation. In turn, they ask to be taken off of the mission and are electrocuted repeatedly by Nue. Minori Mitama summons demons to attack the school, and during this time a sleeping sand is released on all the humans. Nue enters and takes down Nozomu, and chases Kouta and Chizuru down. When they are cornered, Kouta refuses to leave Chizuru to her death and discovers his fox powers. Kouta possess Chizuru and turns into a five-tailed fox. He defeats Nue and Minori Mitama, who makes an oath to make Kouta her own one day. Chizuru's breasts, and thus her spiritual powers, are restored.
