"My name is Ruud Ra Kan! I am the second son of the Demon Kin Sik, the true master of this world!"
Ruud Ra Kan was a demon in Lucid Adventure. He was the second demon prince and son of the Demon King, Sik. Along with most of the other demons, Ruud Ra Kan was sealed in the Demon World by the Ancient Knights after the demons lost the Human-Demon War.
Ruud Ra Kan was released back into the world along with other demons after the seal on the Demon World was broken by Nightmare. He served as one of the Generals for Nightmare and was told to stay in Jelly Village by No Name.
Eventually, Ruud Ra Kan engaged the Grass Roots Guild, forcing The Best Swordsman to his 100% True Awakning for the first time. After a long battle that involved Ruud Ra Kan getting Nightmarized, Ruud Ra Kan was eventually killed by The Best Swordsman.
Due to his actions and role, he is one of the main antagonists in the Beyond the Boundary Arc.
As a Demon Prince and a direct descendant of Sic, 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.
He despises the weak and feels it is beneath himself to fight them. He was annoyed that Drip Soup and Cocomori dared to draw their swords at him despite what he considered weak swordsmanship from the both of them.
As a Demon Prince, he feels disgusted when compared to other demons that are not of his rank as he showed when he was compared to Ligos.
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.
"...You're the strongest human I've ever met" ― Ruud Ra KanThe Best Swordsman was the only member of the Grass Roots Guild that piqued Ruud's interest. Ruud Ra Kan was impressed with The Best Swordsman because he was able to counterattack immediately after Ruud kicked him into a mountain and also deflect his Dark Ball, although he was still a disappointed with his power when compared to the Ancient Knights. The Best Swordsman was the only member of the Grass Roots Guild that piqued Ruud's interest.
