Korekiyo Shinguji, also known as Kiyo, is a character featured in Danganronpa V3: Killing Harmony and a participant of the Killing School Semester.
His title is Ultimate Anthropologist. He has seen many places and people, and as a result, he has formed his pet theory of "humanity's unlimited beauty."
After he successfully participated in the 53rd Killing Game, Korekiyo's memories and past were fabricated by Team Danganronpa as follows: According to Korekiyo, he had an older sister who meant the world to him and knew him better than anyone else. She always had terrible health, and ever since Korekiyo was young, she constantly had to go in and out of the hospital. Because of this, she was horribly lonely and never had any friends, so she spent a lot of time with her brother. When he was younger, Korekiyo got interested in cultural anthropology while reading a book with his sister. He was surprised to find out that different people around the world have had similar ideas that turned into popular stories. His sister told him that he should research it if he was curious about it, and that motivated him to become an anthropologist.
