Yu Long was Ding Xiao Yu's father. He was a martial artist and a talented musician. He was one of the founders of the Martial Arts Syndicate.
He was murdered by Hei Long years prior to the beginning of KO One.
Xiao Yu once admitted that he doesn't like people hitting his head was because his father always hit his head when he was drunk and upset that Xiao Yu did not practice his musical skills.
