Ryoku
Dragon Koi Tournament fighter
Ryoku is a competitor in Yokai's Dragon Koi Tournament who considers the Hero a worthy opponent. His ultimate attack takes so long to prepare that he politely lets the Hero leave while he concentrates. He is still charging it after Kitsune's defeat, until the Hero knocks him down and Miko declares the Hero the winner.
