Strider Hiryu

Strider Hiryu was the youngest Strider to ever reach the rank of "Super-A" grade. He was the greatest Strider the organization has ever produced, but he eventually grew disenchanted with them and retired. An uncollected prologue tells how Hiryu had been forced to kill his sister, Maria, who had inexplicably gone insane. He left the Striders for Mongolia, where he lived in seclusion for some years.
