Byakuya Araki

"The sword is an extension of your body; thus, first master the body."

Background
400 years ago, he wandered into the ogre village. The villagers were suspicious, but the chief warmly welcomed him. Around the same time, a lesser dragon was rampaging in the forest. After expressing his gratitude, Araki defeated the dragon. The villagers hallowed his name and passed down his praise to the later generations. They soon began imitating the lad's attire. He had taught them various techniques, and through trial and error, they learned them.

He later married an ogre in the village and had a daughter, and then became Hakurou's master and grandfather
