Koshijiro was Kaoru's father and was the one who created the Kamiya Kasshin Ryuu and established the Dojo Kamiya in Tokyo. He had worked hard to make such a great style that used fighting as a mean to only to protect lives until the day when he unfortunately passed away. Koshijiro never left anyone in charge of replacing him and carrying on the teachings of the Kamiya Kasshin Ryuu, but he had trained his daughter Kaoru in the style at a very young age after his wife had died. Therefore, Koshijiro's teachings were never left to be forgotten, since Kaoru took on the role of assistant master and carried on the name of the school. He was described to be very strict, very dedicated to his work, but on the inside, a side Koshijiro never showed to anyone with exception of his wife, most likely, he was a sensitive man.
