A third-year student of L'Ecole des Cinq Lumières and usually volunteers to manage the library. Komachi is the daughter of the head of a famed sweets shop. She's calm and assuring, but is pretty scary when she snaps. She's also a novel writer, thus easily getting excited over unnatural things. This 'unnatural thing interest' led her to follow Nozomi, witness the Nightmare, and becomes Cure Mint. Aside of her being a Precure, Komachi also got her novel reviewed by Nuts, also developing a crush on him.
