Taito is torn between having lunch with Saitohimea or eating the meal that Haruka prepared. Luckily, he is saved by a call from Gekkou as insects have invaded the school and school has been cancelled for the day.

The group has arrived at a beach, which is meant to be an intensive training camp and even Izumi was invited to come. Cross tests out their limits and announces that each of them should become powerful enough even to beat ancient dragons.

It seems that Haruka was asked by Cross to cook for the whole group. This leads to a lot of tension due to the love triangle between Taito, Saitohimea and Haruka.

After taking a nap, Mirai is thirsty and Gekkō refuses to buy her a drink. She notices a strange looking potion on the table and chugs it despite Yūichi previously telling her not to touch it. The potion causes the person who consumed it to swap souls (thus switching bodies) with anyone he or she comes in contact with. The main cast spend the day inadvertently swapping bodies due to Mirai's carelessness. This OVA episode was written by the author, Kagami Takaya himself. The episode consists of three short stories, two of which were created based on ideas tweeted in by fans, and one of which is a crossover with another of Kagami's work, The Legend of the Legendary Heroes. Note: Unaired 13th episode bundled with the limited edition of volume 9 of the original novel.
