The characters the story focuses on the most.
Ultimate Lucky Student and Ultimate Hope. The story begins when Naegi wakes up in Ultimate Despair's headquarters, brought there by Komaeda. It then follows him as he tries to fight Despair while planning his escape.
- All-Loving Hero: As in canon. It turns out to be one of his most important traits and why, unlike Kamukura, he's able to redeem some of the Despairs. At the same time, this and his Hope Bringer status are deconstructed, as they are the root cause behind almost all his problems in the story.
- Apologizes a Lot: Naegi develops this trait, especially towards Komaeda.
- Arch-Enemy: Despite trying to save Enoshima's life at the end of the first game, Naegi thinks this way of her after Komaeda is through with him.

- Hes Back: Naegi manages to bounce back from falling into despair after getting a hug from Kirigiri, something that vexes Kamukura to no end.

- Immune to Mind Control: He's the Ultimate Hope. Being immune to despair comes with the territory. Ha ha, no it doesn't.
- He does eventually become immune to mind-control videos, however.
- Instant Expert: On subliminal messaging after Kamukura shows him the video in chapter 43.
- Manipulative Bastard: He becomes noticeably better at manipulating Ultimate Despair.
- Moral Event Horizon: In chapter 99, when he tries to poison Ultimate Despair's prisoners.

- Driven to Suicide: In the penultimate chapter, Komaeda, terrified that he will remain Always Chaotic Evil, tries to get Naegi to kill him.

Izuru Kamukura/Hajime Hinata
(Former) Ultimate Hope and a member of Ultimate Despair. Helps Komaeda kidnap Naegi out of boredom, and is watching Naegi try to escape as a source of entertainment or so he claims. His goals aren't what they seem, and he has plans for Naegi.
It's later revealed that he's reclaimed his memories as Hinata. However, the damage done to his brain during his transformation has permanently altered his personality.
- The Ace: Superhuman master at everything, capable of single-handedly holding off The Future Foundation. Even Ultimate Despair is wary of him.
- Anti-Villain: Kamukura is one of Naegi's primary kidnappers and goes out of his way to ensure Naegi stays imprisoned, but as unbelievable as it seems, he has good intentions.
- The Atoner: Kamukura's actions seem to be based on atoning for Nanami's death and allowing Class 77 to fall into despair.
- Broken Ace: As in canon, he because super talented at the cost of his personality and memories. He's also aware of what was done to him, and has major issues surrounding Nanami and his class. On a positive note, he's been trying to get himself and others out of despair.
- Death of Personality: As in canon. Even regaining Hinata's memories hasn't fixed this.
- Foil: To Kirigiri. Both are very intelligent, stoic characters who keep information close to their chests and have a hard time getting close to others. Both also act as the Chessmaster for their respective groups. Unlike Kirigiri however, Kamukura never learns to trust and bring others into his plans. The result is that Kamukura's plan fails and is only salvaged by Kirigiri, whose plan to locate and reach Naegi succeeded.
- Foreshadowing: Kamukura's first appearance has him declare that he intends to take a neutral position in the Naegi vs. Ultimate Despair fight. However, observant readers will notice that Kamukura does interfere from time to time and it's almost always for Naegi's benefit. This is a major clue that Kamukura was lying, and that he's actually on Naegi's side.
- The Friend Nobody Likes: With the exception of Komaeda, Ultimate Despair tolerates him at best. This is due to Kamukura's arrogance when he first met them and because they believe he killed Nanami.
- I Work Alone: Deconstructed.
- Jerkass: Early Kamukura. However, his Character Development with Nanami helped him shed most of this by the story's start - not that anyone realizes it.
- Master of All: Averted. He comes across as this way in the beginning, but Kamukura's shortcomings are a major plot point.
- My God, What Have I Done?: Both he and Komaeda have this reaction to Naegi falling into despair.
- Neutral No Longer: Kamukura has several of these over the course of the story, including after the Steering Committee murders Nanami, when he realizes Enoshima took advantage of him and turned his class into Despair, and when he realizes Naegi is actually succeeding at reforming Ultimate Despair.
- Unwitting Instigator of Doom: He helps Enoshima kick off the Tragedy.
Ultimate Nurse and a member of Ultimate Despair. One of the quickest to accept Naegi, she starts fawning over him like a mother.

- HeelFace Turn: The first to be cured of despair.
- Heel Realization: Has one when she realizes Ultimate Despair plans to mutilate Naegi.
- I Just Want to Be Loved: The positive attention Enoshima gave her is what caused Tsumiki to be so vulnerable to despair. Conversely, this trait also makes her the most vulnerable to Naegi's influence.
- Mama Bear
- Parental Substitute: Early on, Tsumiki tries to invoke this with a creeped out Naegi. Eventually, a relationship like this does develop, but as sweet as it is, it's ultimately a side-effect of Naegi's immense trauma.
- Sudden Principled Stand: In-story, Tsumiki's demand to stop her medical torture show is this. Played with though in that her problems isn't that she's torturing people, but that it makes Naegi upset.
Ultimate Swordswoman and a member of Ultimate Despair. Unique in that she hasn't actually fallen into Despair.
- Animals Hate Him: Kuma has a natural dislike for her.
- Character Development: Learning to disobey Kuzuryuu is a major character arc for her and turns out to be the key to breaking him out of despair.

- Sudden Principled Stand: Pekoyama has one when she finally confronts Kuzuryuu.

- Kick the Morality Pet: Kuzuryuu orders Kuma to be killed after Naegi causes a group vote to swing against him, even though Naegi himself was not present at the vote and never knew anything about it.

- Pragmatic Villainy: Naegi proves to her that her right-hand man, Phillip, thinks she is a tyrant. Although this is her Berserk Button, she spares Phillip because he's still very loyal to her and hasn't actually done anything wrong.
- Self-Made Orphan
- Utopia Justifies the Means: She is willing to burn down the rest of the world if she feels that would protect her country. Unfortunately, she is unable to see her actions are counterproductive to her desires.
- Big Eater: She used to be this, and denying herself food is how she brings herself despair.
- Even Evil Has Standards: Nidai is a nice guy, but he's still Ultimate Despair. However, he draws the line at offing a member of Ultimate Despair's "family."
- Team Mom: Nidai shows traces of this in how he protects his classmates, such as backing Tsumiki up when she tries to convince Owari to break her hunger strike and giving Naegi a pool break after seeing how physically worn down he is. Notably, Nidai doesn't need explicit intervention from Naegi to break out of despair, and does so after Shirokuma orders him to kill Naegi.

- Big Eater: He used to be this, and denying himself food is one way he brings himself despair.

- Aren't You Going to Ravish Me?: He isn't satisfied unless Makoto treats him with the same level of disdain and disgust as Junko did.
- Big Brother Instinct: Develops one towards Naegi.

Though technically not one of the Survivor Six, Fujisaki's AI works with the survivors trying to help Naegi.

- Heroic Sacrifice: In chapter 90, to help Naegi and Iwata escape Ultimate Despair.
- Ultimately averted. As Alter Ego himself points out, as an A.I. with multiple copies, destroying his Monokuma body won't actually kill him. Sure enough, he later appears on Kirigiri's cellphone.

Toko Fukawa/Genocider Sho
Ultimate Writer, or Ultimate Serial Killer as Sho.
- Unwitting Instigator of Doom: It's revealed that before kidnapping Naegi, Komaeda approached Sho to talk about taking Naegi in. Her explanation that Naegi would never abandon his friends prompts Komaeda to take Naegi by force. Additionally, because Fukawa and Sho do not share memories, her classmates weren't warned that a stranger had taken an interest in Naegi.
- Survivor's Guilt: Suffers from this. Failing to protect Naegi hasn't made it any better.
Ultimate Fortune Teller.
- Unwitting Instigator of Doom: Hagakure's cowardice played a major role in Komaeda successfully kidnapping Naegi.

Tropes common to the Future Foundation:

- Good Is Not Soft: Deconstructed.
- Hope Bringer: The purpose of their organization.
- Slave to PR: The Survivor Six's status (especially Naegi's) as the world's Hope Bringer means that the Future Foundation has to be very careful handling Naegi's kidnapping and disciplining his classmates. Kirigiri and Togami exploit this ruthlessly.
- Well-Intentioned Extremist: As in canon.
