A naive, hot-blooded young man with a strong sense of justice and sensitivity to the conflict between duty and emotion. Ken is not good at doubting others, which often leads to his unhappiness. He has once played as a goalkeeper at the Japanese professional soccer. However, he was disgraced by a game-fixing gambling scandal and expelled from the J-League, then someone tried to kill him. He has recently learned that it was all a case of entrapment by Kouichiro Kase, whom he had believed to be his best friend.
