Ep. 4: Klub Sastra Klasik mendiskusikan misteri seputar pengusiran paman Eru
Tayang pada 14 Mei 2012

The club organizes a meet-up to discuss Eru's uncle's mystery. At Eru's house, each member (consisting of Eru, Houtarou, Satoshi and Mayaka) presents their summary of research and their theories. When it is Houtarou's turn, he asks to use the toilet, then pieces together his own theory from all of the other members' presentations. He explains that Eru's uncle and other students might have negotiated with the teachers not to cut short the period of the Culture Festival, but the price was the uncle's expulsion from the school. As the mystery is solved, all members leave, but Eru still wonders why she cried at her uncle's words. (Source: Wikipedia)
