Character Profile: Sakyo Valdez

Sakyo has got long hair, eyes that shift in color, a bad attitude, and he smokes and gambles. But Sayko started out living a plain life, though he despised his own family. As a young boy he found a thrill in death, killing harmless animals (pulling the wings off of flies, breaking puppies legs, running cats over with his bike). When he took a job at a pet shop, he cut out the hearts of animals just to see how long they would live. Then he got older, and found a thrill in gambling when there were lives on the line. And he made a fortune in it.

Sayko is most seen in the Dark Tournament as the manager of Team Toguro. He develops feelings for Shizuru Kuwabara. Before the Yusuke/Toguro match, Sakyo proposed a bet that the manager of the losing team dies, and Koenma accepted. When Yusuke won, Sayko activates the stadium's self-destruct system and remained as it collapsed. He wanted to use the prize money from winning to complete his two-way gateway from the Human World to the Demon World. But as he is to die, he wanted to make sure no one could continue his research.
