Saroshin Roku was born shortly before The Night of a Thousand Devils, and lost his parents during that skirmish. Roku never new his parents, but he had the support of the village. The Omo No Kage, Ganjiro Shinomura, saw potential in him, having known his parents. He decided the boy would be inducted into The Shinobi Corps as soon as possible. Through all the trials and tests, Roku kept cool under pressure and proved to be a capable field agent. He quickly rose through the ranks, and was among the first to respond to The Laozi Invasion. He's been the defacto leader of the Heroes of Hokkai, and has most recently risen to the rank of Acting Scoutmaster of the Shinobi Corps, due to injuries sustained by Seiki Mitsuteru in the field.
