Hyouka was produced by Kyoto Animation, with directing by Yasuhiro Takemoto, series composition by Shoji Gatoh, and character design by Futoshi Nishiya.

However, his plan is interrupted when his sister forces him to join the school's Classic Literature Club, which is at the risk of being disbanded.

To Houtarou's dismay, Chitanda gets in the way of his 'energy conservatism' by asking Oreki to solve problems every time her curiosity arises.

He informs the club's traditional anthology "Hyouka", is a pun: translated in English means "I Scream" (Ice cream).

This pun is a warning by Chitanda's uncle, where he wanted to tell future club members to voice their opinions.

With Eru's uncle's case resolved, the club members start preparing their annual anthology, "Hyouka".

However, other members of the Club pose flaws in his theories, and as Houtarou investigates more, he discovers Irisu's true plan: Irisu never intended to find the "true" ending of the movie, but instead made a cover-up to make Houtarou the new author, since she thought Hongou's script was too boring.

Houtarou and the club begin to investigate, and realize the robberies are taking place in alphabetical order, a mock crime of The A.B.C.

Jiro tried to send a code to the school's Executive Committee President, Muneyoshi Kugayama, who has quit art and the project they were working on despite being talented, which angered him.

Unfortunately, Kugayama is unable to decrypt this code because he never read what the writer wrote and the incident is passed off as a funny prank.

In the New Year Festival, Houtarou and Eru end up getting trapped in a wooden hut but successfully escape after sending a message to Satoshi.

As spring arrives, Eru asks Houtarou to join the Hinamatsuri, which is disturbed by a construction happening early on a bridge used in the festival.
