A wizard over 140 years old who lives in a cavern in the Amazon jungle. He appears to be of Japanese origin, but little else is known. Although he cuts a somewhat comical figure, his total lack of greed and ambition have allowed him to become the master of skills beyond those of any ordinary man. Using his experience and his unflagging athletic abilities, Oro's movement flow freely. Even motions that appear wasteful show very little opportunity for the opponent to exploit. Out of boredom, he embarked on a journey to seek out the ideal successor of his school of earth magic, but he has been unable to find any fighter worthy of his real effort. After some deliberation, he sealed the use of one arm by magic, so apart from mealtime, he is limited one arm for his daily affairs. Sometimes the magic seal swaps arms while he sleeps.
