蒼芽

One of the eight members in the Hakkenshi, a group of the most powerful users. Because of his tricky fighting style and his quirky nature, he also has the nickname Magician. At the 8th Training School where he is the leader, he orders his trainees to call him Master.
He is the master of a mysterious fighting technique called Souga Style, but this is originally a technique from the ancient times, so it is unknown whether he invented it or not. Souga might not even be his real name, when various people in many places gave him different titles.
