- Sibling Yin-Yang: His children are polar opposites of each other. Uma is masculine, brash, has a deep tone of voice, and is unafraid to pick fights while Shika is feminine, soft spoken with a falsetto tone, and prefers to use peaceful methods when interacting with others.
- Split-Personality Takeover: For the Japanese version, the reason he was assigned to the Talent Removal Program was in fear that his puppet friends were taking over his original personality.
- Talking to Themself: Technically fills this trope since his "children" are merely extensions of Mitsunari.
- You Gotta Have Blue Hair: His hair is a faded avocado green.
Voiced by: GT
He has trouble socializing, but otherwise is nothing more than a typical teenager. He is calm and quiet, and is polite towards everyone he speaks to. It's rumored that a soul will always enter the afterlife if you hire his services.
In Miwashiba's version, he is the first victim where he was strangled by Maiko and thrown into an open locker.
In the English dub, he becomes the third killer after he's manipulated into killing Aruma thanks to Seishi.
- Did Not Get the Girl: In the English dub, Saiji had a crush on Maiko but was unable to act on them since she was the first victim.
- Foreshadowing: Miwashiba's profile for him describes him as the group's corpse checker... with a conspicuous question mark. In Miwashiba's version, he never gets a chance to check a corpse... for he himself becomes the first corpse.
- Friendless Background: He admits that he never made friends before the killing game. He considers his classmates to be his first friends.
- The Generic Guy: Apart from his lack of social skills, Saiji is the most normal among the guys for his plain appearance and personality.

- Mangst: In the dub, he has a tendency to reflect on his feelings for the late Maiko and how he blames himself for not being able to help her in time.

- Nightmare Fetishist: A downplayed example. While discussing the state of Kego's corpse, Saiji went into unnecessary detail about the different parts of the decaying body.
- No Social Skills: He has a hard time socializing with kids his age since most of his time is spent around dead people and their families. In Miwashiba's version, this was the reason why his parents signed him up for the Talent Removal Program.
- Sanity Slippage: In the English version, Saiji's mental health becomes more deteriorated as the story progresses. It gets to the point that he becomes manipulated into killing Aruma. Averted in the Japanese version, as he dies before it can happen.
- The Smart Guy: Saiji's skills in handling corpses and analyzing the state of the body become very useful during the second trial.
- Spared by the Adaptation: He is the first victim in Miwashiba's version, but he manages to live until Chapter Three in the unofficial dub.
- You Gotta Have Blue Hair: It's a grayish shade of blue.

A mature and kind man who has been in the public eye for quite sometime. He has a large following of fans due to his looks. He acts like a stereotypical gentleman and is courteous towards those who offer him the same respect.
In the original version, it's all a front. His real name is Zen Katagiri who is actually the Ultimate Hitman. He joined the killing game because he was hired by the government to assassinate Ayumu in order to end his destructive bad luck.
For the dub, he still maintains his true talent and proves to be a dangerous threat to the group. After receiving several attacks from different students in the fourth chapter, he meets his end after Marin tries (and fails) to save him.

- Karma Houdini: Despite being outed as the mastermind of the double murder scheme of Chapter 3, Seishi doesn't face execution since Saiji, his puppet, was the first one to commit a murder.
- Laughing Mad: He does this after Mikoto reveals his dark side in the third trial.

Voiced by: Mahou
A half-black, half-white tiger robot that seems to be the headmaster of Precept's Peak Academy and claims to be the mastermind of the killing game. Because it is an AI, it functions completely on it's own.
For the dub, he ends up being executed alongside Mikoto.
- AI Is A Crap Shoot: He's a robotic A.I. and is the overseer of the killing game.
- Cats Are Mean: He has the head of a tiger plush toy and he's as mean as far as killing game mascots go.

- Dude, Where's My Respect?: He laments to himself with how the kids have no respect for him.
- Screw the Rules, I Make Them!: He boasts this ability when he decides to rewrite a rule into allowing him to kill the students should they fail to make progress with the trial. It's subverted in the third trial when Mikoto reveals that Monodora, being a programmed A.I., can't create new rules or kill the students on a whim.
- Suspiciously Similar Substitute: Apart from his design, his personality is identical to Monokuma.
Akira Tsuchiya and Narumi Osone
The main directors of the killing game in the English Dub. Despite having contrasting motives and goals, the two Ultimates joined forces to take over the Precept's Peak Academy's system as part of their plan to revolutionize the world.
- Birds of a Feather: They relate to each other due to having lost a family member who was a former Ultimate and now wants justice for their death. Although they didn't get along since Akira is fueled by despair while Narumi was motivated by hope.
- Breaking Old Trends: Narumi stands out as the first mastermind who was motivated by hope rather than despair. Additionally, she also survives the killing game rather then being executed or killed for her actions.
- Demoted to Dragon: In the original version, Akira was the only person who organized the killing game. In the dub, he became Narumi's second-in-command while she became the main mastermind.
- Engineered Heroics: Narumi's Evil Plan involved infecting the Japanese public with despair using the Junko A.I. Akira found which would be impossible for the government to manage on their own. With everything going to hell, Narumi and her legion of Ultimates known as the Hope's Angels would swoop in to drive away the despair and restore society. This in turn would create a positive image for the Ulimates and allow them to return to the public eye without discrimination.
- Evil Wears Black: Akira wears a black jacket and he's the mastermind in both versions.
- Freudian Excuse:
- Akira's participation in the killing game was to avenge the death of his beloved grandmother: a former Ultimate who was the only person who was close to the boy. But due to reports that her written works were infecting the public with despair, she was assassinated by the Phoenix Foundation. So Akira became motivated to kill his grandmother's killer while also tearing down society with the power of despair.
- Narumi's reasons for organizing the killing game was because she blames the Japanese government for killing her father. Her father was a former Ultimate who frequently protested the rights of talented people who were now being oppressed but he lost his life after a police officer shot him on accident. Now Narumi intends to carry out his will by dismantling the oppressive government and creating a better world for everyone.
- For the Evulz: Apart from avenging his fallen grandmother, Akira's motivations are not as noble as Narumi's. He intended to unleash the Junko A.I. for the sake of watching the world crumble into ruin and wasn't interested in restoring it like his partner.
- Friendly Enemy: Despite being outed as the mastermind in the later chapters, Narumi proclaims that her feelings of friendship towards the remaining students are genuine. She even wishes them good luck during the final trial.
- Well-Intentioned Extremist: Despite her role as a mastermind of the killing game, Narumi's motivations were based on changing the corrupted values of modern society in the hope that Ultimates can be accepted without prejudices like before. She also stands out as a mastermind who is fueled by hope.
- Wounded Gazelle Gambit: Her Evil Plan was to create a series of killing games that would draw the attention of the public to show how the talented masses were being mistreated and abused by the government. She even intended to pass off as one of the unfortunate survivors.
