A man with brown curly hair and a simple, fragile-looking impression. He stands between the late 170s and early 180s in centimeters. He sacrificed his left eye to escape a ghost story and now wears a medical eyepatch to cover the empty socket. He is an extreme egoist, obsessed with practical benefits and caring only for himself. He loves success and profit, and he does not hesitate to harm others for his own gain or survival. He seems to be a ruthless person who will do anything, no matter how low, to protect his own safety. This earned him the nickname "Viper," as he is a man of relentless persistence who keeps crawling back no matter how much he is stepped on. He is a two-faced individual who approaches strangers with a simple and weak demeanor, judging whether they are beneficial to him. If they are, he drains them; if not, he uses them and throws them away. If it means he can live, he will shamelessly try to read the room and flatter even the objects of his fear without feeling any sense of humiliation. However, he is far from incompetent; rather, his skills are so outstanding that they create a terrible synergy with his awful personality. While he desperately looks out only for his own profit and survival and is willing to use or sacrifice others without hesitation, he is not the type to take pleasure in seeing people in trouble or find joy in tormenting them.
