Йомі

Is the newest of the Three Kings. He is the former second in command to Kurama's brigand prior to Kurama placing his soul into a mortal. Yomi, however, was reckless, losing countless men in unauthorized raids and direct confrontation, thinking it more exciting that way. Kurama, angered, sent an assassin to kill him, who failed but blinded Yomi. Yomi then grew extra ears and tuned his senses so acutely he could eventually hear all within his kingdom. He plans to take over both the demon and human planes, calling on Kurama to his side. He fights Yusuke in the tournament, barely winning after hearing Shura's shout, and loses the next round due to his injuries.

Yomi then leaves to properly raise and train Shura, thanking Yusuke for helping him achieve a sense of peace he could not have attained on his own.
