Once more Mihoshi gets ahead of Subaru and set a training camp for him and the female basketball club aiming for the upcoming mixed basketball tournament. Much to their surprise, they find that Natsuhi Takenaka, the captain of the boys' team will also participate, but he refuses to play alongside Maho and both start fighting on several occasions. Subaru and Tomoka come with some plans to have them get along but with no success at all.

But both end up watching Maho seriously training by herself, and Subaru questions Takenaka if Maho is really just playing around as he claims.
