Editor of "Sloth"
Voiced by: Toshiyuki Toyonaga (Japanese), Kyle McCarley (English)
A man of common sense and seriousness. He can be a bit too serious at times, making him inflexible. He wishes to protect others with his truthful articles. He is the protagonist for the prologue and Stage 1.
- Acquitted Too Late: Only finds out he was innocent after humanity went extinct.
- Alliterative Name: Haruto Higurashi.
- Covert Pervert: After listening to Ryo's rants about bondage, he ends up being the one most interested in it, even attempting it after Ryo's boss fight is over.
- Driven to Suicide: Jumps off Mashiro Garden Tower in the intro out of guilt for how his article got the interviewed woman killed.
- Dying Message: At the end of the game before dying of old age for good, he realizes that there is another survivor on Earth, telling Sachika of this before dying.
- Geek Physique: Scrawny and wearing glasses.
- Heroic Sacrifice: The end of Stage 6 has him murdered by Kurosuke to save the others from being killed, this usually wouldn't be a problem in this game. But when they come back it turns out Kurosuke has destroyed his X key.
- Heroic Self-Deprecation: His inner monologues about sins are ridden with this, and he is not very confident about his status as the group's leader. He tones it down after finding out he wasn't actually responsible for the article scandal that got him fired.
- Idiot Hair: Like the Danganronpa protagonists before him.
- My God, What Have I Done?: When he finds out the woman from his article was killed because of the photo published in it.
- My Greatest Failure: A photo in one of his articles led the interviewed woman's abusive ex-husband to find and kill her. Subverted as Haruto wasn't the one who put the photo on the article.

Zen Kubota

A farmer who works deep in the mountains, and knows more about survival than the average person. Contrary to his cute face, he's cynical and often makes fun of others. He is the protagonist for Stage 2.
- Abusive Parents: Zen's grandfather (and biological father) is single-handedly responsible for Zen's anger and trust issues.
- Animal Motifs: Monkeys, just like his father.
- Broken Pedestal: Loses all his respect for his mother and his Morality Pet Rumiko after finding out about their affairs with his grandfather.
- The Bully: He strangles Ryo once in retaliation to a joke, and teases the idea that Renji hated Yuma. This backfired in his backstory when he tried to tease Rumiko by revealing his own secret.
- Cruel to Be Kind: Throughout Stage 3, he makes rather cold remarks to Minamo and harshly dismisses the group's attempts to console her in regards to having to kill the boss, who happens to be her little brother. This was done by him in order to push her to go through with it.
- The Cynic: Claims to be a realist and initially has a hard time trusting his fellow survivors, specially Yuma and Sachika.
- Death Seeker: States in the prologue that he really doesn't mind dying.
- The Exile: Is practically disowned by his family after harming Rumiko and is ordered to never set foot in their house again. Although his grandfather stated that if he plays his cards right, he would’ve made Zen his heir after his death.
- First-Name Basis: He explicitly asks to be referred to by his first name when introducing himself, immediately hinting his hatred for his family.
- First-Person Smartass: Not that he isn't snarky enough out loud, but his inner monologues in Stage 2 had a lot of this.
- Foil: To Yuma. Both are considered as the Token Evil Teammate. While Yuma loves her father to the point that she follows his every command, Zen hates his biological father.
- The Gadfly: Switches his The Bully tendencies to this after his Character Development.
- Generation Xerox: Not as evident as the other examples in this game, but Zen and his biological father make this sort of comparison to each other a lot in the most climatic moments of Stage 2.
- Heroic Self-Deprecation: When facing the Stage 2 boss, he calls himself a monkey son identical to his father.
- I Lied: Tries to pull this on Rumiko after telling her about his family situation. She doesn't buy it because he was tearing up.
- I Work Alone: Goes through the second floor of Monkey Treehouse Village alone so no one else would watch his past. It doesn't work because Extend TV broadcasts simultaneously on all televisions.
- Insane Troll Logic: When asked if he is fine with killing his own family, Zen claims that sparing them would be unfair to the other creatures they've killed.
- Loving Bully: After his Character Development.
- The Rival: He TRIES to be this to Haruto and Yuma, but it gets quickly dropped after his stage.
- Secret-Keeper: Doesn't reveal his grandfather's relationship with his mother and Rumiko to rest of his family, claiming it would only make everything worse for everyone.
- Ship Tease: With Yuma after his Character Development. When the Mashiro Group is revealed to be behind MANI, he is the only one to trust her immediately and convinces everyone else to follow suit. But then he stop backing her after she has some involvement in trying to kill them
- Smoking Is Cool: Loves his cigarettes as seen when he was sulking. Due to his skill as a farmer he considered using tomatoes and eggplant leaves as tobacco substitutes.
- Smug Smiler: Doubles as Stepford Smiler most of the time.
- Screw This, I'm Outta Here: He attempts to do this in his Stage 2 by exploring the ruins alone so no one else would have to watch his conquest videos. He doesn't get very far though, as the group finds him shortly afterward and Extend TV apparently plays on all of the TV's in the ruins.
- Token Evil Teammate: More of a confrontational Jerkass than properly evil, but Zen is this for the first two Stages of the game.
- Used to Be a Sweet Kid: He once had a positive outlook on life, until he learned the truth about his grandfather and just replaced it with anger.

The only daughter of a big company boss. Exceptionally rich. She often does things at her own pace and has a cold attitude to go with it, and can be an elusive woman. She is the protagonist for Stage 4.
- Ambiguously Bi: While never outright stated, her relationship with Rinko, in both the story and in their bedroom events, really ends up testing the boundaries of a Pseudo-Romantic Friendship, such as Yuma outright saying she wants to get closer to Rinko, with Rinko asking if they can hold hands. Should she reach the "Intimate" level with her, Yuma will outright say Rinko has become "enamored with her body", with Rinko responding that she's "head over heels". On the relationship page, Yuma will also say that they are "more than friends."
- Animal Motifs: Swine. While a massive glutton, she's also a very articulate and smart woman, as well as crass, bad-mannered and coarse (or, in other words, boarish).

The Bella Moi, in addition to goal plushies, is also riddled with mutilated pig plushies, likely symbolic at the abuse she endured from her father.

- Big Eater: She is the one who portrays her sin in the most literal sense. She is prone to "air eating" at the mention of good food.
- Broken Bird: Copes with her mother's death by rejecting her sense of self in order to become a perfect replica of her. This includes a sexual relationship with her father.
- Cloud Cuckoo Lander: Appears as this sometimes, as she mostly appears to go on tangents in the most important moments, as if to actively ignore the plot relevant events. It's intentional on her part, since she already knows most of the mysteries from the get go and doesn't want the rest of the party to figure it out.
- Deadpan Snarker: She can certainly be witty if she wants to.
- Death Seeker: Not only for herself but for every human clone ever.
- Full-Name Basis: With everyone.
- Generation Xerox: Invoked. Yuma dedicated a huge part of her life to become a replacement for her late mother.
