Ryu was an orphaned child, with no knowledge of who his parents were or if
they are still alive. When Ryu was a young child, he was adopted by a man named
Gouken and began living with him as well as learning a mysterious martial art.
Gouken would later train his best friend's bratty son, ken masters, who served not
only as a sparring partner for Ryu, but also to give Ryu some company since
Gouken was the only person Ryu had seen in a long time due to the seclusion of
Gouken's dojo. Ryu looked up to Gouken as a father figure during his early years
and Ken as a best friend and surrogate brother, which is how their relationship
remains to this day.
