Korekiyo Shinguji is a character from the Danganronpa V3: Killing Harmony video game.
A person who's been all over the world studying folklore. Seeing the adversities found in poor areas of the world has led to him believe that hardship can bring out the true beauty of mankind, so he eagerly observes the events of the killing game.
At the end of Chapter 3, it's revealed that Korekiyo had an incestuous relationship with and eventually developed a female Tulpa based on his late sister. He is also the culprit of Chapter 3, killing Angie Yonaga after she catches him setting up a death trap that he would then use to stab Tenko Chabashira in the back.
In the XP4 fics, Korekiyo is brought back to life. Korekiyo is a member of the Heroes Coalitions as a trainee. He also attends the Vanguard Academy as a student.
Korekiyo is a tall, slim student with rather pale skin and long black hair. His hair is stated to follow an archaic image of beauty and it "puts his female colleagues to shame". He has narrowed yellow eyes, and his mouth is covered by a black mask, covering his mouth and neck, with a zipper where his mouth would be, giving him an unsettling and mysterious appearance. He wears the mask wherever he goes, no matter where he goes, and he even owns different masks for eating, showering, and other daily activities. When his mask is removed, it is revealed that he wears lipstick as the appearance of his tulpa that was based on his late sister.
He wears a dark green military-style uniform with knee-high black boots, a zipper lining the front and two straps over it. The uniform consists of a white button-up underneath it, a dark green button-up, a red armband around his left arm from his previous school, Sunset Hills High School, a green military regulation cap with his former school's insignia on the top, and a decorative chain dangling from it. In his Free Time events, he states that his sister tailored his uniform for him while she was sick. He wears what appears to be some kind of silver locket around his neck. Both of his hands are completely covered in bandages, although it's likely he's not even injured and that this is actually related to sorcery.
In the prologue, he wears the uniform of his original high school. He dons a black, unbuttoned blazer with golden cuffs and a grey knitted vest with a v-neck. He doesn't wear a hat like in his anthropologist uniform, and his hands are completely uncovered. He wears grey slacks and brown school shoes. He still wears a face mask, although lacking its zipper.
Korekiyo is an aloof and somewhat creepy person, but he is also very cool-headed and intelligent. He has the experience of having met to a huge variety of human beings for his cultural anthropology research and because of that, he can keep himself composed even under the confinement circumstances and believes in facing things with calm and rational approach rather than an emotional one. He has a vast knowledge of different cultures and ponders different subjects in deep and complex manner, with him occasionally starting lengthy anthropology speeches even though nobody asked. He is greatly interested in topics he does not necessarily agree with as well, as he states he does not believe in any gods, but he finds them interesting from the point of view of studying the human nature and cultures. However, he does believe in ghosts and souls, and has a strong interest in communication with the dead and death in general.
Thanks to all of his knowledge, he has formed a pet theory of "humanity's unlimited beauty" and he has a deep interest in it. He believes all human beings are great, and that even their ugly sides are extremely beautiful and beauty can be created from hardship. During the killing game, he observes other students with great interest in seeing what kind of beauty they will display as humans under such circumstances, seemingly not caring about their safety. It has been stated that Korekiyo is so interested in anthropology that it sometimes seems like he is not as interested in the currently living people. His morals are stated to be a bit off and he can say unsettling things rather openly, like randomly mentioning that Gonta could use his immense strength to crush a child's skull easily. In Chapter 1, he openly states he has no problem with killing and wonders why the others do, stating that killing is perceived as wrong only because of laws made by humans and such laws do not exist in the killing game. He is aware that his appearance and behavior cause him to come across as a potential murderer, but he does not appear to care what other people think of him. He claims the others should not fear him as a potential murderer, as he merely wishes to observe.
Korekiyo usually speaks in calm and polite manner, but he nevertheless comes across rather off and makes others uncomfortable due to his strange and sometimes morbid thinking. While he is most of the time very collected, with his voice staying the same tone, he occasionally gets very excited about some topics and his voice turns notably more high-pitched. He also tends to stay calmer than the others during bad situations, as for him it's an opportunity to observe, though even his spirit begins to break during the Death Road of Despair and Gonta's Insect Meet and Greet. In Chapter 3, there is also a moment when his tone changes to more a panicky one when Kokichi touches his ancient katana without permission and he fears it might get damaged. He then disturbingly threatens to tear out all of Kokichi's nerves in anger, though his voice still remains creepily calm. In general, he tends to find noisy and vulgar people annoying, often asking them to be quiet. Furthermore, he also has a unique and somewhat creepy laugh, which sounds like "kehehehe". In the original Japanese, "kukuku" is his unique laugh's sound.
As another strange trait, he is quite fixated on keeping his mask on. During his free time events, he claims he has a different mask for different activities, like eating, bathing, sleeping and exercising. However, they all appear exactly the same and do not seem to have any kind of hole in them, yet he is somehow capable of eating and drinking. According to Korekiyo, he takes his mask off only in front of people his sister deems trustworthy. He occasionally speaks on behalf of his sister, for example, by telling someone that his sister is pleased with them or that she doesn't trust them yet. The other students either do not understand what he is talking about or do not notice it. It's later revealed that his older sister is actually deceased and that he is a serial killer whose goal is to kill a hundred women he considers "pure", believing that they will become "admirable friends" for his sister in the afterlife. After suffering from traumatic torture and a near-death experience in the past, he developed a female split personality, or tulpa, based on his sister, which serves as a coping mechanism against feelings of exceptional distress. While normally very calm, stress can cause him to have a panic attack, rendering him hyperventilating and unable to talk properly. The sister persona acts reassuring towards him, but also gives orders which Korekiyo seems to obey without any questions. The persona also seems to dislike other people in passive-aggressive and condescending manner, referring to the other students as "ignorant children" and "such a sorry lot".
Korekiyo is obsessed with his sister and claims to be deeply in love with her, with her appearing to be the only person he truly cares about, and many of his mannerisms like his hair and clothing being inspired by her. He is also noted to wake up two hours before the morning announcement and spends an entire hour getting carefully dressed with no hurry. Because of these traits, he is perceived as very effeminate by the other students, and is occasionally mocked by Kaito. Korekiyo even claims that he and his sister were in an incestuous relationship, and because of this he only kills women, as he jealously refuses to let other men close to her even if he deems them good people. In his Love Suite event, it's implied that he is willing to have physical relationships with other people "out of curiosity", even if it's not consensual, but he states he would never love them as he considers his sister his only true love. Unlike most students in the series, he apparently has lots of experience with sexual relationships, as he has described himself as being very popular with local women in a village which commonly practiced bondage. He is sadomasochistic, enjoying the pain of others because he considers the raw emotions beautiful, and enjoying his own suffering because he believes it makes him closely connected to his deceased sister. However, he is also shown to be very romantic and strongly believes in the "power of love", which can make even the impossible possible. He is very fond of romance and love stories, especially ones centered around forbidden love. Even though he is apparently willing to have strictly physical relationships with other people, during the bonus mode Love Across the Universe he refuses to look at pornography, because he has "already given his heart to someone".
After he is revealed to be the culprit during the third trial, Korekiyo feels no guilt for his terrible actions and he seems to genuinely and unironically consider the other students his friends, not seeing any contradictions between this and his own actions. This is yet another trait that indicates that he is unable to truly understand and care about how other people feel, though he is also quite skilled at noticing other people's intentions and emotions due to keenly observing other people for years. He panicked at first, but slightly hesitantly calmed down after his sister ordered him and told him that he should accept his defeat. In the end, he does not even seem to mind his own death that much, as it's a way for him to finally reunite with his sister. Among his last words, he mentions that death is never acceptable for humans and the living must find find a reason to accept it whenever it happens, no matter how forced, explaining why so many cultures have funeral rituals and rumors about resurrecting the dead. He says that he came to the conclusion that the way you come to terms with death also determines how you live, all of this indicating that he is in some ways aware that all he has done is just a coping mechanism against his sister's death. He promises to look over his "friends" as a ghost, and creepily states that he'll be watching how they will face the deaths of their friends. Though at first content with his execution, as he believes he will be with his sister once again, he is lastly seen reacting with utter horror and disbelief as both his sister and Monokuma banish his spirit to the afterlife.
Korekiyo's talent as the Ultimate Anthropologist is a fabrication made by Team Danganronpa. Due to that fact, it is unclear whether Korekiyo traveled around the world as an anthropologist in the past.
Korekiyo is an anthropologist, to be precise, a cultural anthropologist that researches customs, legends, folklore, poetry, etc. His particular field of study is culture and ethical customs whose historical origins have yet to be made clear, like shichigosan or setsubun. He tries to inspect and elucidate those kinds of traditional customs from a rational perspective and states that cultural anthropology is like a science that tries to observe humanity itself.
Korekiyo is very knowledgeable about folklore and customs across the world, as he stated that he had done a lot of field trip by traveling around the nation to study various culture, tradition, and custom in various places. As shown in his Free Time Events, he is very familiar with folklore from Indonesia(Hainuwele) and Greece (Medusa), as well as many folklore from his home country Japan. Myths, folklore, and legends are all inform anthropology, that is the reason why he extensively studies them as an anthropologist. He studies nursery rhymes, lullabies, and traditions and events expressed in song as well.
In his opinion, fieldwork is very important to anthropology. Hearing legends recounted firsthand, recording tools or lifestyles are examples why it is very important to do a fieldwork. Because culture is constantly changing, as an anthropologist, Korekiyo said that he must keep the present in mind while he learns about past customs.
He is shown to be a great teacher and story teller. Korekiyo managed to pique Shuichi's interest in learning a lot of stuff related to anthropology after he got involved in extensive discussions with the Ultimate Anthropologist. In his Fifth Free Time Events with Shuichi, the two of them promise to do a fieldwork together someday, and Korekiyo is pleased to make the Ultimate Detective as his first disciple.
- In the official art book, Korekiyo is stated to strongly dislike Cleansing Air Freshener and gets furious whenever someone uses it, because it apparently repels ghosts and paranormal entities due to the holy water mixed in. This seems to explain his dislike for air conditioning.
- His favorite myth is the Medusa, knowing her original status as a mother goddess who was later depicted as a hideous monster, and believing that this is because developed human society begun to think about overcoming nature instead of being dependent of nature goddesses. He also likes the story because it shows that people can't run away from death no matter how much they overcome the nature.
- Korekiyo has romantic feelings exclusively for his sister and claims they were in a relationship, but this is not confirmed and could be a delusion caused by his mental state. It's also possible that all of these memories were created by Team Danganronpa and his real relationship with his sister, if he even has one, could be very different.
- Korekiyo is the second character in the series to have a split personality, the first being Toko Fukawa. Unlike her however, his split personality is more like a tulpa than a multiple personality disorder. He also only kills women, which is somewhat similar to Genocide Jack, who only kills men.
- Korekiyo and Genocide Jack's similarities are acknowledged during a one scene in the non-canon bonus mode Ultimate Talent Development Plan, with neither being the other's "type", and both appearing to be vaguely aware of what the other does to the people they are interested in.
- Korekiyo has shown some similarities to Norman Bates from Psycho, including being in love with a female family member and having a split personality based on said female family member.
