a Chord is the leading vocalist of the band Dong Cheng Wei (東城衛), which he continued to be until he was promoted to be the new leader of Bei Cheng Wei (北城衛) after the previous leader was killed by Zack and Xia Tian decides to join Dong Cheng Wei as the new leading vocalist. He is somewhat of a funny guy, who does not know the appropriate time to talk. Although a Chord is part of a supernatural army, he does not manifest any special ability or weapon until Lan Ling Wang begins to sneak around his team and the Xia family and he reveals his powers for the first time.
