Mayo serves as the protagonist of the series. She is a sixteen-year-old student at Yotsubadai High School and a member of the Basketball Club.
During eighth grade, she spotted Taka working at an ice cream parlor and fell in love with him instantly. Taka remains unaware of her feelings for him. Since he only had eyes for Miaka, Mayo's first true love was never realized. As her life unravels around her—marked by Taka's marriage to Miaka and the impending divorce of her parents—Mayo enters "The Universe of the Four Gods" to secure a storybook ending with Taka.
