Yakamo no Oni was the newest Oni Lord to find a name, and was often regarded as a threat by the others. It had existed with definition for a fraction of their lifetimes, yet it considered itself their equal. Yakamo shared a name with Lord Sun, the very symbol of the incorruptable spirit. Finally, in bizarre mockery of the Crab Thunder Hida Yakamo whose name it shared, Yakamo no Oni had refused to take part in the world of mortals and stood watch with its spawn at the gate of Jigoku.
