Ep. 17: Eru mempertanyakan tindakannya saat Klub Klasik gagal melindungi naskah Hyouka dari Juumoji.

Eru finishes her talk on the school radio but has misgivings about whether she was doing the right thing. Later, she admits to the Empress, after Fuyumi gives the same advice to her, that following the Empress's example in manipulating people is not for her. Her radio talk however sets the events into motion and the room of the Classics Club gets filled with students, expecting to help prevent the last strike of Juumoji. Volumes of the Hyouka sell fast. However, they are apparently unsuccessful in protecting the manuscript of Hyouka, which catches fire and a note from Juumoji appears in a printed copy of Hyouka. Mayaka has some suspicions because she sees water on the table where the manuscript was and she notices that Satoshi is strangely silent and irritated about the events. It turns out that Houtarou was not only an investigator in this case. (Source: Wikipedia)
