An Kuze, a 12-year-old girl, is deeply passionate about Shogi and aspires to become a professional player. She possesses an exceptional memory, allowing her to recall anything she has seen just once, a trait she shares with her Shogi-playing grandfather. However, this ability comes with a drawback: she cannot forget anything, including negative emotions. To pursue her dream, An joins the Encouragement Association, where talented young Shogi players gather to hone their skills and compete for a professional title.
