Master Asia was the primary alias of Gundam Fighter Shuji Kurosu, a character that appears in the anime Mobile Fighter G Gundam. Master Asia was Domon Kasshu's teacher as well the former King of Hearts of the Shuffle Alliance. In the latter half of the series as Master Asia was more commonly referred to by his other alias, Undefeated of the East.
He has a very stoic and strict personality, but he is also a person of character, and although he doesn't express it in words, he is extremely compassionate. Although his words are harsh, he is also kind to his beloved apprentice Domon, who he fights many times even after they become enemies. His personality has earned him the awe and respect of the people.
The school that the Master created, "Undefeated of the East," is said to have been born from the spiritual parentage of heaven and earth, and to have received its birth from the great power of nature. It is unique and powerful in its own right. While it is a skill that can compete with MS on an equal footing even in the flesh, it is said that only a few, including the Master and Domon, have mastered it.
