Korekiyo Shinguji

"Korekiyo is aloof and somewhat disturbing, but he is also very cool-headed and intelligent. Having met a wide variety of human beings during his experience in cultural anthropology fieldwork, he can keep himself composed even under confinement circumstances and believes in facing things with a calm and rational approach rather than an emotional one. He tends to stay calmer than the others during dire situations. As for him, it's an opportunity to observe. However, even his spirit begins to break during the Death Road of Despair, and he becomes panicky during Gonta's Insect Meet and Greet. His morals have been described as being "a bit off." He is highly passionate about his talent and can get excited when talking about it. It is shown when he panics after Kokichi touches the katana in his lab without permission, fearing that it may be damaged, and threatens to tear out his nerves. He ponders different subjects in a deep and complex manner and occasionally shares his knowledge in lengthy, unsolicited anthropology speeches. He has formed a pet theory of "humanity's unlimited beauty," believing that all human beings are beautiful, including their "ugly sides." That beauty can be created from hardship."
