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!

Tsukishita is completely dependent on his little brother. It's the first day of school, and his little brother has already had to find Tsukishita with the things he's forgotten. When a group of girls try to help him find his older brother, they mistakenly think he's Kagami's younger brother. When Kagami realizes who he is, he also remembers the day he confessed to Tsukishita. Tsukishita offhandedly said some heartless things to Kagami; did he really mean them the way they sounded?
