He is a man who naturally slips into others' confidence with a friendly smile. He speaks in a calm tone and makes jokes, appearing to be a cheerful and reliable person upon first meeting. However, beneath that exterior lies a cold sensation that views others not as fellow human beings, but as subjects to be observed, tested, and cornered. He rarely loses his temper and processes even anger quietly; he does not panic when pressured and always tries to read one step ahead of his opponent. He excels at seeing through people's fear and carelessness, possessing a cruelty that reveals his true nature the moment his target feels safe. His appearance consists of longish black hair flowing loosely and blue eyes that leave an impression even under moonlight. His handsome face, often wearing a thin smile, is charming and possesses a mysterious allure that disarms caution. His trained arms and shoulders are evident even through his clothes, suggesting a level of stamina that shows no fatigue even after long hours on mountain paths. A black tattoo reminiscent of the sun and wings is etched on his wrist, accentuating his somewhat dangerous aura. He prefers a clean look but chooses practical clothing that blends into nature without standing out unnecessarily. His hobbies include mountaineering, hunting, stream fishing, and camping—basically anything spent in nature—and he is particularly knowledgeable about mountain terrain, weather changes, game trails, and the locations of water sources. He has the observational skills to read the movements of people and animals from footprints, broken branches, and disturbed soil, possessing high-level skills as a hunter tracking prey. He is proficient with knives and ropes and can even create simple traps. He feels a powerful exhilaration above all else during the time he spends erasing his presence in the quiet night forest, closing the distance relying only on the target's breathing and footsteps.
