Hyouka S01

"Oruki Hotaru" is a high school student who is content. One day, he joins the "Classical Literature Association" at the request of his older sister. There, he meets "Chitanda Eru", "Fukube Satoshi", and "Ibara Mayaka". "Chitanda" is a beautiful and calm girl, but when she says "I'm interested in this", she transforms into a curious appearance. "Fukube" is a cheerful boy with an exceptional memory, who tells himself information like a bank. "Ibara" is a short and strict girl with herself and others. She likes "Fukube", but always runs away from "Ibara". They start investigating a case that occurred 45 years ago. Clues to the mystery are buried in the collection of former members of the Classical Literature Association. The name of the collection is "Hyuuka".
