Orga Itsuka

A leader among the boys of CGS. Naturally gifted as a commander, and trusted implicitly by the others, he strives to live up to their admiration. He's especially close to Mikazuki, who he's known since a very young age; their bond is closer than most blood brothers. His coup within CGS is launched to give the boys a place where they won't be betrayed anymore.
