Bocchi's classmate, and the most popular person in class. Her classmates call her Mīna. She is a terrible (and loud) singer. She used to go to the same elementary school as Kō Futō, who was her only friend then. Since Kō refused to go to school, she decided to make her classes fun so that Kō doesn't feel nervous. Her name is derived from mina ga warau (皆が笑う, "everybody laughs").
