Maki is a second-year high school student and Urushi Yaotome's best friend. She possesses long hair ending in curls and perpetually wears a cat-like smile, a feature that fuels her popularity despite her expressing no romantic interests. Her personality is cheerful and mischievous, often manifested when teasing Urushi about Ayumu Tanaka's feelings. Maki actively engineers opportunities for Urushi and Ayumu to be alone, serving as a supportive figure in their relationship. While generally lighthearted, she reveals genuine concern for Urushi's emotional well-being, particularly regarding Urushi's first experience with romantic feelings. Maki's knowledge of shogi rules is limited, yet she boasts greater proficiency than Urushi—a claim strategically employed to avoid playing Rin Kagawa. She occasionally tricks characters like Ayumu, Takeru Kakuryu, and Rin, effortlessly capitalizing on their occasional denseness.
