Age: 37

Though 37 years old, Mimi has the appearance of a preteen and refers to herself as the "eternal elementary school student."

Mimi's youthful appearance caused her significant difficulties in her adulthood, as many people assume her to be a child. Despite these issues, she eventually came to view this as an asset, and she swiftly rose through the ranks of the Goha Corporation to become one of the Tops of Hexagon, Goha's executives, and even had a son, Yoshio.

She uses this situation to infiltrate Yuga's school as a transfer student to get information about Rush Duels.
