A 6 year old black dragon (he was 4 years old at the beginning of the story) who started following Cale after he was saved by him from Venion Sten. He was imprisioned and tortured by Venion for the span of four years. Cale gave the Dragon the name Raon Miru, pure Korean for "Joyful Dragon" after the black dragon asked him to do so. He possesses destructive impulses but looks out for his newfound family. Raon would give tear-soaked apple pie slices to Cale whenever Cale overused his powers or got hurt.
