It's Inuzuka and Persia's celebratory one month anniversary. The campus is abuzz due to the return of a certain student. Her name, the first princess of the West, "Chartreux Westia". Char walks the red carpet with composure as the White Cats laud her arrival. Inuzuka, tasked with opposing Char, is struck by her words. "You're dating Persia, right?" Has their love already been discovered?

The Black Doggies have begun their training camp in preparation for midterms. Persia dons her "Julio" disguise and participates at Inuzuka's request. In charge of the camp is Inuzuka's childhood friend, Hasuki Komai. Inuzuka learns by chance that he's the reason Hasuki is so dedicated. Guilty about keeping his relationship with Persia hidden from Hasuki, Inuzuka gathers his courage.

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.

Contenders for 'MVP' set their fighting spirits alight as the sports festival begins. Among them is a determined Inuzuka, now having been promised by Persia that she will entertain one request of his if he becomes MVP. The games progress with neither the Black Doggies nor the White Cats giving an inch, until finally the 7th event, 'Stick Down', is upon them. That's when the trouble begins.

Inuzuka asks Persia on another date, this time to the Harvest Festival at a lake near campus. Not long after, the twin sisters 'Kochou Wang' and 'Teria Wang' appear before him. They may look immature, but the two 14 year old Black Doggy House prefects are prodigies that skipped to the second year of high school. Can Inuzuka have a normal date with Persia while these two watch his every move?

Romio is occupied with finding a way to buy a present for Persia's birthday in a week, and acquires permission from the twins to go on an errand to Dahlia Street. But despite arriving in town with vigor, Romio can't decide on a present. That's when he runs into Char. He accompanies her with the promise of gift advice, and things get interesting when their shopping date runs into some trouble.

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!.
