The Dahlia campus is even more lively than usual with students training tirelessly for the upcoming sports festival. Aby Ssinia, a White Cats boy, and the girl after his heart, Somali Longhaired, appear before an obstinate Inuzuka. Aby aims to be a prefect, and in an effort to solidify his popularity among the White Cats, he approaches Persia. Inuzuka, unable to contain himself, speaks out.

Romio is returning to his room after his shopping trip with Char when the head of the Inuzuka household and Black Doggy prefect, as well as Romio's brother, 'Airu Inuzuka' stands in his way. Airu raises concerns, and suspects Romio may be in contact with a White Cat girl. Romio, beholden to his brother, undergoes a week of surveillance. The problem is, that week coincides with Persia's birthday.
