Akaten Hero!

from drmaster: yuji midorikawa is your typical high school student whose has a secret identity: he is “green” in the high school battalion unit, gakusei 5 (g5 for short). g5 is the special unit trained to fight and protect earth against the invasion of the dreaded galactic force “gurdark” and its sexy queen mayura. but green has a problem. he really can't fight, and always ends up hiding behind his other team mates. what ensues is a witty and wild ride as our “imperfect hero” struggles to maintain his reputation as a “guardian of earth” while keeping up his grade point average in school!
