Another day, another confrontation between Touwa's Black Doggy House and the West's White Cats House. All the while, Inuzuka and Persia continue their secret romance. Then, the day of the tri-monthly outing to the town of Dahlia arrives. Inuzuka concocts a plan for a date with Persia. He disguises her in a Black Doggy boy's uniform. Things get spicy as they try to keep their date on the rails.

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 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.

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 enters the White Cats dorm to celebrate Persia's birthday at all costs. While searching for Persia, he encounters the White Cats prefect, 'Cait Sith', and the two face off. Romio stands no chance. Though disheartened by their difference in strength, Romio doesn't quit, and fiercely runs at the window. His last hope. Will Romio and Persia's hands be joined as they climb the world's walls?
