Appears indifferent and realistic on the outside, but is a 'soft-on-the-inside' type who definitely takes care of her people (especially her contractor, Deokgae).

Personality: Appears fearful and slightly timid, but displays immense courage in decisive moments. Highly sensitive and possesses great intuition. Traits and Abilities: His innate amount of mana exceeds human limits to the point that even dragons covet it.

He is an expert at handling troublemaking dragons but is firm when it comes to safety.
