MatsuA solitary ex-soldier. Left the Sacred Arms after witnessing the murder of his best friend Sai at the hands of his superiors. Once he found out, he tried to exact his revenge by annihilating the unit but was attacked by the Arm's secret weapon: A demon they had said to have slain 20 years ago. The attack left him with the demon's blood coursing through his veins. Now he travels the lands searching for a new purpose; something that will make him feel alive again and not like the wretched demon inside him.
