High school freshman Houtarou Oreki has but one goal: to lead a gray life while conserving as much energy as he can. Unfortunately, his peaceful days come to an end when his older sister, Tomoe, forces him to save the memberless Classics Club from disbandment. Luckily, Oreki's predicament seems to be over when he heads to the clubroom and discovers that his fellow first-year, Eru Chitanda, has already become a member. However, despite his obligation being fulfilled, Oreki finds himself entangled by Chitanda's curious and bubbly personality, soon joining the club of his own volition. Hyouka follows the four members of the Classics Club—including Oreki's friends Satoshi Fukube and Mayaka Ibara—as they, driven by Chitanda's insatiable curiosity, solve the trivial yet intriguing mysteries that permeate their daily lives. Oreki Hotaro is a high school boy, who always acts passively. One day, he enters “Koten Bu (Classic Literature Club)” as recommended by his elder sister. There he meets Chitanda Eru, Fukube Satoshi, and Ibara Mayaka. Chitanda is a calm beautiful girl but she turns into an embodiment of curiosity once she says, “I’m interested in it (Watashi, Kininarimasu)”. Fukube is a smiling boy with a fantastic memory, he never deduces anything on his own. Ibara is a short girl and is strict with others and herself.
