Once a talented professional soccer goalie in the J-League, he was forced to quit due to a gambling scandal, despite the fact that he was completely innocent. It turns out his best friend, Koichiro Kase, drugged him so he would throw a game in favor of the gamblers. Ken doesn't know this, however, and is beaten up and left for dead in a burning warehouse when Kase tells him he found the leader of the gambling ring who set Ken up in the first place. Ken doesn't discover Kase's lies, believing him long gone, until he meets Kase some years later, attempting to figure out why his best friend is one of Weiss's targets. In the end, Kase, who is working very close under a man whom Weiss needs to kill, sets Ken up once more, giving him a false lead and then shooting at Ken himself. When Kase sees him one last time, Ken doesn't grant him any mercy, although he is tormented by his actions afterwards.
