The spirit that infests Ryou and that taunted you just moments ago, the one I call Yokai. He had tried to kill me when I first arrived.

The Penalty Game I gave him has made him wary enough to not try anything again yet, either to me or while I'm present, but a beast can only be put at bay by punishment for so long.

Be cautious of him, Jounouchi. He can do far more than he appears to be able to.
