Mayo is a sixteen-year-old girl who attends Yotsubadai High School and is a member of the Basketball Club. When she was in the eighth grade, she saw Taka working in an ice cream parlor and instantly fell in love with him; however, Taka was unaware of her feelings towards him and only had eyes for Miaka. She found the The Universe of the Four Gods as it was being taken for recycling, but then lost it on a bus. Years later, she finds the lost "The Universe of the Four Gods" again while she walking home one night. When she opens it, she instantly learns about Miaka and Yui's adventures in the book. Heartbroken to learn that Taka is married and his wife is pregnant with their first child and with her own parents about to be divorced, Mayo feels her life is falling apart. She opens the book again and enters it in hopes of getting a storybook ending with Taka. In doing so, she becomes the new Priestess of Suzaku.

In the book, she tells outrageous lies and tries to make people hate Miaka. When she tries to make Reizeitei, Hotori's son, believe Miaka was a bad person, he chastises her and wonders if Mayo can save anyone. With the world out of balance, Mayo begins disappearing and then realizes she was being used by a fake Suzaku. She tries to kill herself, but Taka saves her. Both Mayo and Miaka disappear, but are saved when Miaka summons the true Suzaku to defeat the fake. At the end of her adventures, a wiser Mayo returns to the real world.
