Rouga is quick tempered and slightly arrogant.
He has long dark hair, and a scar on his right eye. He has piercings on his ear.
In his hometown of Ren Village, he was a pretty famous bad ass known as "Mad Rouga." Even on the battlefield he made a bit of a name for himself.
He was assigned to the Hi Shin Unit sometime before the Coalition Army Arc. He heard some good things about him. He wanted to make sure no one walked over him. And wanted to smash the first person he saw, and make him fear him. He was then bumped by Den Yuu. When he saw his size he was to intimidated to punch him. Later he is bumped by Kou . As he goes to punch him he is easily taken down by Kou, because of the joint locks that Kou learned from Kyou Kai.
