Hyouka

Synopsis

The Kan'ya Festival is approaching, and all four members of the Classic Literature Club are unable to sleep from the anticipation of this festival. Houtarou greets his sister in the morning, who says that it is a tradition for the Classic Literature Club to always face some kind of trouble during the festival. She gives him a broken fountain pen before he leaves. The Classic Literature Club meets before the starting ceremony to fix one problem; Mayaka was supposed to order 30 copies of their anthology, but they end up with 200 instead. The club comes up with the plan to first convince the Student Council to move their inconveniently placed club to a new stall, and also to advertise their club by entering various contests under the club's name.
