Ariake approaches the Student Council after her shoes have been vandalized, and a note saying "Quit the Athletics Club" is left in her locker.

Zenkichi is more skeptical, citing their lack of evidence, though pair do manage to find the culprit even so (senior Isagi Isahaya, though Ariake remains unaware of this fact). The next day, while wondering why no one appreciates his style, Zenkichi is approached by Ariake, who tells him that the sneakers she was using to train with were replaced with new running shoes and a note saying "Sorry".
At a later date, Ariake is seen running with Isahaya. Isahaya scolds her for taking too long to get changed, and if they do not hurry they will miss morning practice. Ariake apologizes, but questions why Isahaya waited for her, commenting that she has been a lot nicer to her lately. Isahaya insists she has not, and not paying attention, crashes into someone. When Ariake asks if she is all right, a flustered Isahaya asks who that was. Ariake identifies him as Kouki Akune, the prince of the Judo Club.
