Webcomic / M9 Girls!

Superheroines with a sense of fashion...
M9 Girls! is a webcomic by Rulopótamo, first drawn by Kanela and later by Séreméla.

The M9 Girls are Any, Pato, Claudia, and Karla. They are a team of college researchers who gain the ability to tap into the primordial power of the universe and become endowed with superpowers as a result.
