Chihaya Ayase is a frank and ebullient girl who becomes fascinated by the obscure world of competitive karuta, a card game based on Japanese poetry. Introduced to the aggressive style of the game by a quiet and thoughtful elementary school classmate named Arata Wataya, the two quickly become close friends. They start playing as a group with Taichi Mashima, Chihaya's smart and athletic childhood friend, until they have to part ways during their middle school years due to several circumstances. As their high school life begins, they meet once again.
