Prince of the Dwarf Kingdom. Because he carries dragon blood, he is large for a dwarf at 170cm. Rust-colored hair and green eyes inherited from his father. He was born because the King of the Dwarves offered a princess to a dragon to prevent the dragon from attacking the kingdom. The dragon loved the princess, but when she died giving birth, the dragon despised the child and handed him over to the Dwarf Kingdom. Since the Dwarf Kingdom prizes strong blood, he was educated as a candidate for the next king and raised with Spartan discipline to value strength. He has a serious and kind heart, but because toughness is demanded of him, he suppresses his kindness and plays the role of a stalwart warrior. He fears he will have no place to belong if he isn't the person he's expected to be. In truth, he likes cute things.
