Suetsugu, Yuki

Always deemed inferior to her elder sister, the strong-willed yet aimless Chihaya Ayase has no dream of her own. In contrast to her, Taichi Mashima, the son of a surgeon, is gifted yet insecure as he is burdened by the heavy expectations of his strict mother, who wants him to be perfect in everything. However, the lives of Chihaya and Taichi soon change as they encounter Arata Wataya, the new transfer student in their class.

Inspired by Arata's dream to become the best at competitive karuta—a card game based on the classic anthology of one hundred Japanese poets—Chihaya quickly falls in love with the game. Refusing to lose to the talented Arata, the prideful Taichi joins along and immerses himself in the game, aiming to one day surpass his fated rival. The three friends spend their childhood practicing karuta everyday, until certain circumstances force them to part with each other.

A few years later, now in high school, the trio finds themselves reunited through the world of competitive karuta. Alongside their newfound comrades and rivals, they embark on a journey of self-discovery, friendship, and romance.
