Tatsuya Shirogami

Ryuji's late father who was killed by Odawara. Also known by his title Nidaime (the 2nd generation). Ryuji grew to look almost exactly like him. He was admired much by Kamo-san. He had a promise with Kaya regarding her sister that Ryuji fulfilled and took personal interest in Kamo-san's intent on getting revenge. He had given Ryuji to Kamo-san after he was released from the hospital, giving him the name 'Ryuji'; the name Kamo-san was planning to give to his son. [Source: Wikipedia]
