S1·E52 Twin-tailed Tsundere Girl

The Sket Dan get a request from Saaya, a girl who looks and acts like something right out of a dating sim game. She wants to try and get rid of her tsundere tendencies toward boys, and so starts coming to the clubroom everyday in an attempt to become comfortable speaking with the opposite sex. Later, Saaya finds an abandoned pet owl in the park and the Sket Dan end up caring for it in their clubroom. Owls are supposed to be carnivorous and hard to raise, but... this one is almost ridiculously tame.
