Noriko Aoyama is a second-year high school student who struggles with social awkwardness and making friends. After moving from a small town to Kyoto, she hoped that a fresh start at a new school would change everything. But her clumsiness, frequent social missteps, and a streak of bad luck soon make high school life more complicated than she expected.

To make things even more confusing, she can't seem to ignore the guy who is the class creep, while at the same time she catches the attention of the most popular boy in school. Amid all this, Noriko finds herself becoming a key member of the school's chess team in battle for Kyoto high-school chess championship.
