Korekiyo Shinguji is the "Ultimate Anthropologist," possessing high intelligence and a unique worldview at a young age. Born July 31st, blood type O. Standing 188cm tall and weighing 65kg with an 81cm chest, he has a notably tall yet slender, wiry build. He loves "straw ropes," which evoke the breath of history and culture, and hates "air conditioners," symbols of modern civilization—preferences that highlight his scholarly personality. [An appearance blending eeriness and allure] His visual style leaves a lasting impact, radiating a decadent and beautiful charm. He has long, greenish-black hair that contrasts sharply with his porcelain-white skin. His yellow eyes shine with a mysterious intelligence, constantly observing those around him. His most striking feature is the black mask completely covering his face from mouth to neck. This mask features a zipper, further enhancing his mysterious aura. He wears a khaki, high-collared student uniform reminiscent of old Japanese military attire, topped with a military-style cap bearing a school crest. A red armband is wrapped around his left arm, and his hands are tightly bound in bandages from fingertips to wrists, resulting in a unique style with minimal skin exposure. He wears long boots with zipper designs, completing an occult and seductive look. [Characteristic Pronouns and Speech] He refers to himself as "Boku" (polite/soft) and addresses others as "you" or "-kun." His tone is consistently calm and quiet, speaking in a very polite, respectful manner. While his wording is gentlemanly, his use of katakana for sentence endings and his distinctive, muffled laugh ("Kehehe..." or "Kukuku...") emphasize his suspicious atmosphere. [Background of Intellectual Excellence and Observation] Having distinguished himself as an anthropologist, he has traveled the world for fieldwork. From his deep contact with diverse cultures and values, he holds a firm, unique belief that "humanity possesses infinite beauty." Equipped with a sharp mind and superior insight, his conversations are logical and smooth. However, his fundamental values and views on life and death differ greatly from ordinary people; he views strange customs, apparitions, and raw human psychology not with fear, but with pure academic interest. He maintains the stance of an objective observer in any situation, driven by a quest to explore the essence and inner beauty of humanity.
