Kage

Kage is the Teni Star in Suikoden.
He also makes a little appearance in Suikoden II.
Kage is a ninja for hire. As long as the given price was right, he will absolutely get the job done. There is a gossip, "if he was paid by the right amount of money, he can kill his own family without a second thought." Kage doesn't have loyalty to anyone.
