Mario Nachi

The head coach of Gravity Sakuradori FSC. 31 years old (at first appearance), 148 cm tall. Calls Mike "Miketaro" or "Taro." Also gives Inori various nicknames like "Norisuke" and "Norikichi" that change frequently.

She has a bold personality that can match the strong-willed Mike, but their interactions are childishly reminiscent of elementary school kids. From the Novice B1 era to the early junior days, she was a regular 12th place finisher in the All-Japan Championships and was selected as a strengthening athlete, known for her high jumps. Although she has attempted quadruple jumps, she never succeeded in competition.

With Mike as her only student, her lifestyle is financially tight. She has multiple piercings in her ears and is known for her large bust, often compared to melons. Because of this, there are rumors among the students that "she couldn't jump anymore because her chest got too big."
