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.

The sports festival's finale, 'Cavalry Battle' is where Inuzuka and Aby face off to settle things. Due to Inuzuka's provocations, an unprecedented overtime takes place. Inuzuka sympathizes with Persia, who wants to end the festival without a conclusion. However, a match is a match. Out of respect for each others' feelings, they just can't let it go. The all-out battle leads to shocking results.
