When this little nerd girl got to liking a good workout it didn't take that long to turn herself into a hot little thing. Though she will fully cover up such that it is hard to tell she has bigger arms than some of her classmates and better muscles than most of the jocks, Marii is still remarkably quite comfortable showing off. A fact made brutally clear when some of the "popular" girls "Pants'ed" her only to cut their popularity in half over this hidden treasure.

Marii is not overly concerned with popularity, just helping her friends and maybe meeting some of her idols.
