Being inspirational to one another, their constant strive for greatness led to a friendly rivalry. The two soon stood out and displayed amazing talent despite of their age. Rudy was an honor student and so was Kris.
Despite being friends with each other, an evil scheme was formed by the nobles. The fight for the representative of Seat of Light. the rivalry became a representation between commoners and nobles, Rudy for the commoners and Kris for the nobles. As the time drew near, they learned that in order to get the Seat of Light one must be defeated and one must remain a victor. Because of this Rudy distanced himself in fear of losing their cherished friendship. In the match for representative Rudy purposefully loses to Kris, after the orphanage director tells him the sponsorship come from nobles. The nobles threatened him that if Rudy won then they would cut down all their expenses for the orphanage. Rudy lost to Kris and was not upset or bothered. Kris realized the scheme was all made from the nobles' dirty tricks. The nobles did not want a commoner to hold the Seat of Light or Academy representative position.

In the Japanese server, it is revealed that Rudy fled into a forest from the Celestial World. He encountered Evan and saved him from a monster attack.

Rudy once again appears in late Season 4 where he encounters Reginleif. Reginleif explains to him that his ancestors, heavenly beings, went down to Gaia world to stop the other heavenly people who were starting a war and stealing the power of Gaia. Reginleif confesses that it was her own ancestors who tried to take power from Gaia and transfer it to the Heavens. Rudy then encountered and fought against an Abyssal creature (resembling Dellons) then after the battle Reginleif asks him to investigate two things, one being the World Tree.
He myth awakens after listening to the words of Reginleif who encourages him to fix his former ways, he agreed to her request and stops the Demon Lords from attacking Valhalla Castle who is already damaged due to the attacks of Gaia's forces.

Personality: He's always been very dutiful and is Evan's role model. He thoroughly follows his principles and obligations as a knight of light and seven knight. He had a sense of self-division but Evan tries to help in that regard. In season 2 he becomes more rational and relativist. He now expresses his feelings in writing rather than being vocal with others. He makes decisions about big issues without discussing it with others. He now doesn't mind breaking some of his principles unlike the past.

- His mythical awakening was hinted in Korea where his regular portrait showed myth awakening stars. He was then revealed early March through a pre-registration event.
- He won an awakening poll in global, beating even Yui who didn't have an awakening in korea server.
- Dev Spike revealed that Rudy suddenly grew white wings when he prayed to the light after agonizing about his duty and responsibility he would carry as a knight of lightness. The people around him were amazed and hailed him as a warrior chosen by light. Rudy is still thought to be a human, his wings not being a genetic trait but rather a symbol of his trust in the light (hence why they change) Kris’ wings indicate his acceptance to the power of the devil as Rudy indicates his acceptance of light.
