This is an BD/DVD-only unaired episode, designated as episode 0. Based on two omakes from the manga, this fan-service focused episode features Minato's Sekireis going for a physical check-up and to a MBI-owned resort. Both outings end with Benitsubasa destroying the building after being inadvertently made fun off by Minato's Sekireis, and both time Homura did not join the activities because he couldn't decide whether he was male or female.
