Another giant race that has abilities close to the Ultra Ruby race, whether it's shooting beams, strength, flying, and expanding their bodies. But their abilities are inferior to the Ruby race. This race has both men and women. The men are less flexible than the women, but they have more strength than the women. However, their strength cannot be compared to the Ruby race. However, even though Rudian's physical abilities are considered the strongest in the race, when he tried to fight Luna, he could not fight Luna's strength at all. On his planet, he is also the head of the solar system care unit. And the place he takes care of is Earth's solar system, which is a special care area because there are many aliens who want to take over and there are many monsters on Earth. But the strange thing is that when these monsters appear, they are usually dealt with with great power. And the Rudian race is also eager to study other races that may be detected on other planets. Therefore, they must receive special care of this star system.
