Keijo!!!!!!!! Season 1 Episode 5

Full-Auto Cerberus!!!!

Nozomi faces Kotone in the class-change race, who dodges all attacks while having her back turned, and chases Nozomi using Cerberus, a move where a ghostly image of a dog is manifested from her buttocks. The two collide, and Nozomi wins, as the running around had charged her vacuum butt cannon move. Nozomi and her roommates all advance to the elite class; Kazane, despite losing, had performed well and cornered Mio, which was why Mio used hypnosis, a move she was banned from using.
