Danganronpa 2.5: Nagito Komaeda and the World Vanquisher

Super Danganronpa 2.5: Komaeda Nagito to Sekai no Hakaimono (スーパーダンガンロンパ 2.5狛枝凪斗と世界の破壊者 lit. Super Danganronpa 2.5: Nagito Komaeda and the Destroyer of the World) is an OVA consisting of one episode, which was included in the limited edition of Danganronpa V3: Killing Harmony in Japan.

It is set after Danganronpa 2: Goodbye Despair and before Danganronpa 3: The End of Hope's Peak High School - Hope Arc, with Nagito Komaeda as the protagonist and portrayed as "an ordinary boy" whose bad luck causes good luck for others. Due to suffering a very traumatic death in the program, his mind created a strange, relatively peaceful world he lives in as a coping mechanism. However, it all begins to fall apart after "The Destroyer of The World" appears.

Synopsis
''Nagito Komaeda wakes up after experiencing death in the Neo World Program. What kind of world he is seeing and why did he wake up?''

Nagito appears to be in a strange world, including students who have been seen before as well as people who never existed. He is an ordinary boy with no Ultimate Luck, attending an ordinary school. Constrained by being the protagonist, he thinks that having a big talent would interrupt his happiness. He believes that living an ordinary life, being moderately happy, while watching his classmates have a normal youth is what's wonderful.

However, one day, a boy calling himself "The Destroyer of the World" appears, having the form of red-eyed Hajime Hinata. He begins the destruction of Nagito's world...

Plot
The 25-minute special begins with Nagito Komaeda walking his ways into school surrounded by various Hope's Peak Academy students. Sayaka Maizono appears, running with toast in her mouth. She bumps into Nagito, which gets him hit by a car, sent flying into a chestnut tree, which makes a cat fall and scratch his face repeatedly. Nagito laments on how he has the worst luck.

Makoto Naegi appears, giving his hand to Sayaka to help her stand up. Nagito then stands up and heads to school and stumbles into his friends Fuyuhiko Kuzuryu and Kazuichi Soda asking him what happened to him, suggesting that he needs to go to the nurse's office to treat him. After the bell rang, Class 77-B was shown in their homeroom class to begin class; Nagito arrives to class with seemingly worse wounds than before, with Mikan Tsumiki excessively apologizing for what happened. While Nagito was in the nurse's office, someone outside made a home run, hit the window and smashed a cabinet with glass and chemicals in the nurse's office, covering Nagito's face with chemicals. Kazuichi invites Sonia Nevermind to a date to drink at the cafe with him after school. Sonia accepted his invitation, making Kazuichi very excited. However, after school, Kazuichi is nervous and is planning on not showing up, thinking that he's not worth Sonia's time. Fuyuhiko and Nagito rally his spirits, Fuyuhiko saying that a man shouldn't back down on his word, and Nagito saying that even without talent, one can still find happiness. With his spirit up, Kazuichi goes on the date.

Fuyuhiko and Nagito walk off together, where Nagito reveals that he despises talent, and that if he could, he would rid the world of talent altogether, that everyone could be moderately happy if talent didn't exist, which frightens Fuyuhiko. He suggests that they grab a non-alcoholic drink, as he insists, but Nagito slips on a bottle and rolls down the road, ending up in a compromising position with Mikan, which angers Hiyoko Saionji.

Elsewhere, a mysterious boy appears, saying that this world is the lowest stratum, and how dull this world is. Several police officers appear with guns pointed at him, but he begins shooting from his fingertips, killing them.

The next day, it is revealed that Kazuichi died, and the school is there at his funeral. Peko Pekoyama informs Fuyuhiko that Kazuichi was not killed in an accident, but was murdered. Fuyuhiko sets off to avenge his death because Kazuichi was like a brother to him. Sonia also volunteers to join him and Peko. Nagito declines, saying that he would only get in the way.

Fuyuhiko, Peko, and Sonia confront the mysterious boy, who calls himself "The World Destroyer". Fuyuhiko and Sonia are easily killed by The World Destroyer, leaving Peko to escape injured. She calls Nagito on Fuyuhiko's phone, asking him to avenge Fuyuhiko for her. Peko then tries to take The World Destroyer on with her sword, but is also killed easily.

Nagito decides to confront The World Destroyer in the building where Fuyuhiko, Peko, and Sonia first confronted him. Nagito, despite having no talent and bad luck, still has a feeling that he can win. The World Destroyer claims that what he's feeling is hope, which sounds familiar to Nagito. With one throw of the baseball, he manages to undo all the screws on the building's girders, wanting to take The World Destroyer out with him. With Fuyuhiko's gun, he fires to the side, the bullet ricocheting back to shoot him in the head.

One of the girders that fell on Nagito is lifted, revealing him in his regular attire. The World Destroyer says that the world has been successfully destroyed, and the background changes. The World Destroyer is revealed to be Alter Ego modified to go into psyches. Nagito's death during the Island Trip of Mutual Killing caused psychological instability, and that instability needed to be eliminated. Nagito's classmates were part of his psyche, and a psychological defense mechanism which needed to be eliminated. He is relieved to hear that nothing was broadcasted into the outside world, as he's embarrassed that a world without talent may have been one of his true desires.

Nagito finally wakes up in the real world, with Hajime standing above him. Nagito is confused as to whether he is Hajime Hinata, or Izuru Kamukura. Hajime replies that he's both and that Nagito was the last one out of all his classmates to wake up.

Nagito joins his classmates on the boat, hugging Fuyuhiko and Kazuichi. Hajime offers his hand, which Nagito takes. It's revealed that he removed Junko Enoshima's hand and replaced it with a robotic one. In the end, he takes Hajime's hand as they move aboard, deciding to go forward towards hope.
