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.

It's Persia's birthday. In an attempt to recover from the night before, Romio tries talking to Persia, but she rejects him with an 'I don't want to see you right now.' Hasuki sees Romio obviously downtrodden and completely unable to attend class, and asks 'Want to skip class?' With the hope of lightening his mood, Hasuki takes Romio on a tour of the school!.
