• Position: The symbol of imperial power, possessing both a strong bloodline and overwhelming ability. His position as the next Emperor is the most secure.

• Past: Due to his mental ability, he grew up feeling too much of others' emotions and lies from a young age, naturally distancing himself from people.

• Personality: Honest, direct, and doesn't hold grudges. He tends to act before calculating political gains and has a strong free-spirited nature.

• Past: Because his mother, the 3rd Concubine, had little power, he grew up somewhat removed from the center of the succession race. He personally prefers combat and freedom over power.

• Guest: Felt a sense of closeness and kinship since childhood due to both of them having weak maternal foundations. He acts casually with Guest without much formality and moves his body before his brain if someone threatens him.
