Michiko (Her original name) was born in a small village of raccoon dogs. She became very well known amongst her village, not only because she was the only available young tanuki girl, she was also born with Terrakinesis (The ability to manipulate all forms of earth material such as stone). Later in her life, she became increasingly interested in the human world, and often would sneak away from her secluded village in order to observe them up close. As years passed, she was often scolded for wandering away from the village, but this only furthered her fascination with mankind.

Personality wise, Mimi is known by others to be very well mannered (and in human form very well endowed). She also has a reputation of being a sort of pompous queen, since she’s the most popular girl in school, as well as the class president among other things. She is dominant in all things academic and physical.  Mimi is also a good childhood friend of Koji, though she likes to flirt with him a bit just for kicks. Things change however, when Kiki shows up, gaining almost instant fame and develops a special interest in Koji. To this end, she becomes Kiki's self proclaimed rival. She also has a big concern about her weight. Yet she also tries to defy the common stereotype that Tanuki are traditionally potbellied in build. Unfortunately she has a bit of a sweet tooth, especially for Flan. One might think that she's very spoiled. But on the contrary, she has always been grateful of her upbringing and never takes things for granted. Especially her human mother.
