Ookami-san to Shichinin no Nakama-tachi

Synopsis

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 the Otogi Academy pageant, being loosely based on the story of "The Tortoise and the Hare". Otohime requests the assistance of the Otogi Bank to help her win. Both sides end up using slander campaigns on their opponents, while Ryouko and the other girls somehow get entered as well. Otohime reminisces of how she first became Mimi's rival as well as Tarou's friend. During the pageant, all the females showcase their swimsuit attire, catching the eyes of the audience, though neither Otohime nor Mimi end up ranking. However Liszt Kiriki tells Otohime that she won the attention of Tarou as her only vote.
