Yuan Ka-Fai (ユアン・カーフェイ Yuan Kaafei?) is one of the main support characters in Tales of Symphonia. In the game, he serves as a temporary antagonist, but helps the party later on by offering them Rheiards as a means of transport. Although he is cold and cynical most of the times, he sometimes shows a little more emotional side of himself, especially when talking about his past, and is truly one of the game's protagonists in the shadows.
