Hyouka

Oreki Houtarou, a high school student with a preference for minimalism, reluctantly joins the Classic Literature Club at his sister's insistence. Here he befriends an intriguing ensemble of characters: Chitanda Eru, a mysteriously curious girl who transforms into an embodiment of inquisitiveness when she utters "I'm curious"; Fukube Satoshi, an amiable young man with a phenomenal memory that he refers to as his database; and Ibara Mayaka, a strict short girl who holds high standards for both herself and others. Together, they delve into the unsolved mystery that occurred 45 years ago, using a collection of works from previous Classic Club members titled "Hyouka" as their primary source of clues. As they unearth the hidden layers of this enigmatic case, the group's bond strengthens and they learn more about themselves and each other in the process.
