Korekiyo Shinguji, the Ultimate Anthropologist, is obsessed with the so-called "beauty" of humanity. He is fascinated by every aspect of humanity, and is always keen to see more from the people he spends time with. He is fairly aloof and level-headed, even in the intense situations he is put in. Korekiyo is very intelligent, and prefers to take a more logical approach, as opposed to an emotional one. Due to his strange mannerisms, he often makes people feel very uncomfortable, but this does not deter him.
