Sung Hyunjae

Sung Hyunjae is the leader of Seseong Guild and one of the strongest Korean S-rank Hunters. He holds a particular interest in Han Yoojin and can often be found helping him out.

Appearance
Sung Hyunjae is tall and extremely handsome, a fact frequently pointed out by Han Yoojin. Though he is in his late thirties and one of the oldest Korean guild leaders, he has a youthful appearance.

Personality
Though perceived by the general public as a gentlemanly, distinguished, and well-mannered man, Sung Hyunjae has a reputation for being chaotic and unpredictable amongst Hunters, sometimes described as a madman. He is prone to doing as he wishes regardless of whether it inconveniences or outright endangers other people, and chases after things that interest him with an obsessive and almost-predatory focus. He is generally formal (if not polite), cheerful, and playful when interacting with others, but much like the other born S-ranks, has very few people that he truly feels fondness for. A extremely intelligent man, Sung Hyunjae's actions are by-and-large calculated despite his apparent impulsiveness, and he is not often caught off-guard.

Part of his unpredictability can be chalked down to the fact that as a particularly sensitive and powerful born S-rank, Sung Hyunjae is able to sense that the timeline has been reversed, and has partial access to his pre-regression memories. These half-accessible memories cause him to feel as though he has already lived through the current days (a correct assumption), and thus he feels an overwhelming sense of boredom when going about his days normally. Perhaps to combat this, he takes to deviating from his schedule and doing whatever interests him most.

Sung Hyunjae is also sometimes overtaken by his pre-regression self, at which point he becomes less jovial and playful. He is also quicker to anger and aggression. The possession occurs up until a large chunk of his pre-regression memories are pushed into the combined magic stones of Diarma and the dragon humanoid currently being refined by Han Yoojin.

Trivia

 * If Sung Hyunjae is not where his schedule needs him to be, 99% of the time, the reason is related to Han Yoojin.
