When he was a child, he wore a black long sleeved shirt with a red napkin tied on his collar, red cloth around his waist, black pants and boots.
As a Demon Prince and a direct descendant of Sik, Ruud is extremely confident in his abilities. He considers himself the greatest warrior of the Demon World and always wants to be in the heat of battle. He felts slighted that he wasn't allowed to take direct action in the Great War by No Name. Immediately there was a chance to face a strong opponent, he excitedly rushed to their location.
Just like Ligos and other demons, Ruud Ra Kan looks down on humans. He feels it is an honour for the humans that face him in combat. During the Human-Demon War, he used to go on human hunts.
Ruud respects the strong, regardless of what race they are. Despite the fact that most demons look down on humans, Ruud has shown respect for the Ancient Knights because of their power.

Ruud is extremely proud to be the Demon Prince and the son of Sik and believes that he is the true ruler of the Demon World.
Ruud appears to have a competitive rivalry with his two brothers. He was upset that they were fighting directly in the front lines whilst he was sitting doing nothing in Jelly Village because of No Name's orders.
Ruud begrudgingly accepted No Name's orders due to her freeing him and the rest of the demons. He felt aggrieved and disgraced that she had him sitting in Jelly Village while his brothers were fighting on the front lines which led him to refer to her as a "half-Bitch".
Grass Roots Guild
When one of his underlings reported that humans were attacking them, Ruud was extremely excited to face off against humans once again after a 1000s of years. Apart from the Best Swordsman, Ruud was disappointing in the strength of the Grass Roots Guild members, especially when compared to the Ancient Knights. He even felt offended that Drip Soup and Cocomori even dared to attack him with what he considered weak swordsmanship. When the rest of the Grass Roots members fled, he was intrigued by Choco Bibi's spatial magic.
