A little later, when Miu was suspected of having killed Rantaro by Kokichi, Korekiyo's account was able to prove her innocence.

Korekiyo and the others went to space in the massive ark, the true form of Ultimate Academy of Gifted Juveniles, and were put to a cold sleep for several decades.

Kiyo also has a split personality, similar to that of Toko Fukawa/Genocide Jack, but unlike Toko who had a multiple personality disorder, Kiyo's split personality is a tulpa based on his aforementioned sister and serves more as a coping mechanism over his personal grief and torture that he had suffered years before. Kiyo seems to think that their situation within the Killing School Semester is "intriguing" and that it gives him lots of field work opportunities to observe human behavior at its finest. As a result, this group of students ended up forming the "Ultimate Academy Student Council" with Angie as their president. 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. Much later on in Chapter 5, after the remaining participants cleared the However, the true Mastermind, in order to get the remaining survivors at the time to continue the Killing Game, decided to connect everyone's memories of The Gofer Project to the story of In the Mastermind's rush, they accidentally overlooked slight inconsistencies and plot holes when linking both stories together, such as "Ultimate Despair" only referring to While Korekiyo did remember about the Ultimate Hunt in Chapter 2 and his and everyone else's funeral in Chapter 3 thanks to the Flashback Light's, he ultimately has no complete recollection of the event, as he was Korekiyo was later found in the main hall after the iron bars barricading the front entrance had lifted by Kaede, the Ultimate Pianist, and Shuichi, the Korekiyo would later gather with everyone else in the gymnasium after the Monokuma Kubs made their announcement. Once she pleaded with everyone not to vote for her, and everyone speculated on whether or not she really was the culprit, Korekiyo suspected that she might have merely wanted to gain their trust in order to make it easier for her murder. He believed it was true love and he did not care what the society thought of them.

Her poor health made this a time-consuming effort, and so he treasures it, considering it truly one-of-a-kind. It is also highly likely that during these days he evaluated all the girls trapped within the academy to see if they would make suitable "friends" for his deceased sister, still keeping his ulterior motives hidden from the rest of the group.

Despite this, it was obvious that Angie was going too far the very next morning when the two split parties came into conflict yet again after finding out that the Student Council had blocked off the manhole in the boiler room with a large rock. Angie closed the curtains, but everyone grew increasingly worried as the timer continued to count down and Himiko had yet to come out.
Korekiyo stated that it was blatantly unfair that the student council members were exempt from their own rules, but failed to come to an agreement. During his 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.

However, Korekiyo was unaware that the clues left behind in Angie's murder, the piece of bloody duct tape and the dried blood on the loose floorboard in the seance room would be key pieces of evidence linking both murders together and as a result, pinning him as the culprit of both murders, not just Tenko's. When no answer was given, everyone turned the lights back on in confusion. Himiko is far too shocked to say anything and everyone else aside from Korekiyo was dumbfounded as the second body discovery announcement plays.
Though this slight speech only helped in making him come off as more creepy to the other students.

In the past, according to Korekiyo, he had an incestuous relationship with his older sister.

His particular field of study is culture and ethical customs whose historical origins have yet to be made clear, like 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. When Angie's body was found, Kiyo suggested that they should perform a seance in order to talk with Angie's ghost. He doesn't wear a hat like in his anthropologist uniform, and his hands are completely uncovered. He is one of the 16 participants in the Killing School Semester and his talent is that of an Ultimate Anthropologist. During the Class Trial, Korekiyo took control of the conversations more-so than before, wanting to steer everyone away from the truth. All the Student Council members mourn her passing, wondering just how and why she was killed. The Chapter 3 of the game was meant to feel like a Japanese horror movie, so Kodaka created an Ultimate Anthropologist to fill the role of a character familiar with nursery songs. Korekiyo Shinguji.
