Oreki Houtaro participated in the local traditional festival "Hina Doll Festival" at the request of Chitanda Eru, a member of the Ancient Books Research Society. The content of this festival is that "living dolls" wearing twelve singles parade in the street, but this year due to a communication error, it is unclear whether it can be held. In the end, thanks to Chitanda's idea, the festival was successfully held. However, she was curious about the "mistake" and decided to work with Houtarou to deduce the truth.

The classroom turned into a secret room without anyone noticing, the books were borrowed every week, and the boy insisted that the anthology that should exist did not exist. And hidden in the anthology called "Hyouka" is the truth from 33 years ago - the "energy-saving" young man Oreki Houtaro, who tried not to get involved with anything, had no choice but to join the ancient book research club for many reasons. Later, entrusted by members of the same club, he successively solved the incredible mysteries hidden in daily life.
