Nobunaga Oda

The real Oda Nobunaga. Unable to withstand the political pressure as Nobunaga, he has the identical Saburou take his place while he travels around the country. He eventually ends up taking over the Akechi Clan after the previous leader had no heir, and now works under Saburou (fake Nobunaga) as Akechi Mitsuhide.
