Mamoru "Mamo Ranger" Machida

Mamoru Machida is a character in the Girls Bravo manga and anime. He resembles a stereotypical nerd and often dons the guise of the "Mamo Ranger"(Mamo-Red in the manga). In both the manga and anime, he is shown to be very obsessed with cleanliness. Both accounts showed that this behavior stemmed from childhood trauma where his mother beat him whenever he failed to clean his own messes. (Source: Girls Bravo Wiki)
