Okami-san Gets Caught in the Fight between the Tortoise and the Hare - S1.E3

Otohime is in a rivalry with Mimi Usami who used to call her names when she was a chubby elementary school student. They decide to enter a Miss Otogi Academy contest, and Otohime requests the assistance of the Otogi Bank to help her win. Both sides end up using slander campaigns on their opponents, while Ryōko and the other girls somehow get entered as well. In the end, neither of them end up ranking, but Otohime wins thanks to a solitary vote from Tarō.
