A legendary martial artist and winner of the previous Gundam Fight after defeating Gentle Chapman and Wullube, as well as Domon's mentor. He was a member of the original Shuffle Alliance as the King of Hearts before he bestowed his crest upon Domon and left, disappearing for some time. When Domon reunites with him, they unite to fight the Death Army, but become enemies when he allies with the Devil Gundam. Despite this, he still cares for Domon, as he taught him his ultimate technique to allow him to defeat Schwarz Bruder, who he believed to be Kyōji and knew he would not stand a chance against. The Gundam he used to win the previous Gundam Fight, Kowloon Gundam, transforms into the Master Gundam. Master Asia also has a horse, Fuun Saiki, which uses a mobile unicorn robot controlled similarly to how Gundams are controlled by human fighters and which Master Gundam uses as a steed.

Though he represents Neo-Hong Kong, Master Asia does not join the Gundam Fight until the final round, as per the ruling of the Chairman of All Space, Wong Yun Fat. Upon hearing this, Domon vows to make it to the final round undefeated so that he can take Master Asia's title as Undefeated of the East. Despite his allegiance to the Dark Gundam, Master Asia retains his honor as a fighter, which puts him at odds with Wong because he uses dirty tactics to win.

Having been diagnosed with a terminal illness and knowing that he will die soon, decides to have Domon fight against the strongest opponents during the final matches of the tournament in order to groom him into taking over the Devil Corps and becoming the Devil Gundam's pilot. Master Asia's wish is that Domon will help restore Earth to a pre-humanity state using the nanotechnology from the Devil Gundam. During the 12th Gundam Fight, Master Asia had grown disillusioned with the horrors that Earth endured during the Gundam Fight and that he had contributed to it. To atone for this, he becomes a follower of the Devil Gundam, seeing it as the hope to reverse the damage done. He is the only member of the Devil Corps to pilot a Heavenly King without infection, as his terminal illness prevented him from being absorbed by the Devil Gundam as he originally intended. He dies peacefully after Domon defeats him in the finals, having been convinced by his words that his plan would have failed since he did not consider that mankind is part of nature. Along with Kyōji, Schwarz, and Domon's mother, he appears in Domon's vision during the battle against Grand Master Gundam, where they urge Domon not to give up.
