Doushin Narasaki is a friend of Ryuuzan Arai, and both continue to fight against the Dark Arts and protect Tokyo from demons. He wears sunglasses because he was blinded in his youth while fighting Munetaka Yagyuu. Although he eventually makes friends with Raito Umon, Doushin is a testy old man who doesn't care much for the youths - except perhaps pretty little Hinano Oribe.
