Ken is my next fave after Aya *_* He is a nice guy, dependable, simple and kind. Next to Omi he's a cheerful one. He likes children a lot and playing soccer too. Ken has the nature of giving his heart away, he trusts people easily. This leads him to disappointments though. He is also the typical guy that a girl would want as a partner hehe (watching his epi with Yuriko T__T awww)
Past:
He was a J-League soccer player, he was one of the best and he was popular. He had a best friend named Kase. He was accused of gambling in soccer and drugs which was made up by his friend. Kase became jealous of him. He made Ken drink a bottle of water which is drugged which made him lose consciousness. His friend tried to kill him by burning the room he was into which he didn't know at first. He survived miraculously and met his friend surprisingly. Ken treated him still as the old times but one night Kase tried to kill him. He shot him( he was wearing bullet proof vest). Ken was so despaired to know the truth about his friend. In the end he had no choice, he was forced to kill him.
