Miu decides to depart her Earthly domicile and challenges Ren to a final duel. The contest seems simple enough, but for Miu, this will mean much more than just a duel. Next up, Neneko needs models for her costumes and she recruits Ren and Miu to do the job, leaving Takeya tongue-tied before the bountiful beauties. When Miu wins a local contest, everyone enjoys a trip to the hot springs resort, where the water isn't the only thing boiling over.
