Master Hisashi

Master Hisashi is a elderly martial arts master. He first meets Mitsuo Ishikawa when they bump into each other. The old man senses his strength and asks him to spar with him. Hisashi dodges all his attacks at first, until Mitsuo jumps from behind and continuously punches him. He found the man who could save the world from the Emperor Zowie. He tells him about the legendary swords, Mitsuo doesn't take it seriously and sees it as a fairy tale, but he does go on the journey.

He has a son named Takao who goes along with Mitsuo on his journey. It was revealed later on that, he studied martial arts almost his entire life. He allows Mitsuo and Chandra to stay with him and Takao because they have no home (well Mitsuo was kicked out by his father).
