Atachi, Mimi

安立ミミ

Despite being 37 years old, Mimi looks like a preteen and calls herself the "eternal elementary school student."
Her youthful look caused her major problems in adulthood, since many people mistake her for a child. Even so, she eventually saw this as an advantage, quickly climbing the ranks of the Goha Corporation to become one of the Tops of Hexagon, Goha's executives, and she even had a son, Yoshio.
She exploits this situation to infiltrate Yuga's school as a transfer student in order to gather information about Rush Duels.
