Yuri and Rika's Party and Allies
Yuri Honjo / "Tenma"
- Voiced by: Haruka Shiraishi (JP), Suzie Yeung (EN), Charlotte Hervieux, (FR), Serena Sigismondo (IT), Raíssa Bueno (Brazilian Portuguese)
The main protagonist. Yuri is an upbeat and nice girl who is faced with the danger of this new strange world imposes.
- Action Girl: Gradually becomes this. Around the beginning of the story, she fares as well as you can expect from an ordinary schoolgirl, relying mostly on pure luck rather than genuine skill. Her combat prowess improves as she takes in more information about this world.
- Ambiguously Gay: At one point, she kisses Nise, but it's unknown where she kissed her, making whether or not she returns Nise's affections ambiguous, but she hardly shows attraction to any male character, as there aren't any romantic undertones to her relationship with her brother or the Sniper Mask, merely noting that he is handsome.
- Badass Adorable:An adorable young girl who is also impossibly strong.
- Beyond the Impossible: Her crossing dimension skill can be used to make her bullets hit the target very far away or even to stop events altogether.
- Big Brother Worship: And quite the big one for her brother.
- Big Good: As the manga goes on, it becomes clearer that she is this, being the one that is leading the Helicopter Takeover idea and the ones that basically every character in that manga relies on.
- Boom, Headshot!: Her attack method often uses these.
- The Dreaded: Even by her brother's group, the news that she killed 4 Strong Masks by herself made all of them as amazed as they were afraid of her. By the later part of the story, Yuri is essentially feared even by the Administrator due to her skills and even the Angry Masks avoid her.
- Empowered Badass Normal: She was already badass to begin with but her abilities are boosted after putting on a mouthless mask and becoming a Person Closer to God.
- Guile Hero: She is not above using lies to buy herself some time, as she realizes that the masks will stop if a human declares they will kill themselves and then just watch.
- Guns Akimbo: Her primary weapons.
- Little Miss Badass: She must have gone through many hellish situations even before becoming a God Candidate.
- Locked Out of the Loop: Nise and Kuon decide to not tell her about Kuon's control over the Rail Gun, at least at first.
- Nerves of Steel: Had to develop these, considering the environment she is in.
- Next Tier Power-Up: Eventually, in order to save Nise, she wears a Mouthless Mask and becomes a Person Closer to God. After faced with a hard fight, she manages to unlock the power to cross dimensions, giving her powers to teleport herself and others around and becoming essentially the most powerful character in the story.
- Nice Girl: She is always sweet and polite with those whom she meets.
- One-Woman Army: After using the Mouthless Mask, she is able to take down 4 strong masks by herself.
- Pragmatic Hero: She realizes that in this world, she will have to skirt her morality in a gray line to survive and ensure her friends' survival, eventually growing really comfortable with the idea of killing masks, even knowing they were once humans.
- Senseless Sacrifice: She becomes a Person Closer to God to save Nise, while Kuon and Sniper Mask had already saved Nise.
- Smug Super: Pretends to be this in front of Aohara to prevent him from finding out she's not as powerful as he thinks initially.
Kuon Shinzaki / "The First Judge"
- Voiced by: Akira Sekine (JP), Stephanie Sheh (EN)
A mysterious and sweet girl who turns out to be immune to masks, since she is a Person Who Became Closer To God. Sniper Mask decides to help her find Yuri, so she can have a group and not be alone.
- Amnesiac Hero: She doesn't remember much between using the Faceless Mask and meeting Sniper Mask.
- BFG: She can activate a gigantic Rail Gun from the strange tower using her cellphone, which has enough power to destroy a building while set at level three out of nine.
- Brain Uploading: Survives her 'death' by uploading her consciousness into Sniper Mask's brain.
- Character Death: Dies due to a gunshot behind her, though she manages to survive through Brain Uploading.
- Deprogram: An ability of hers is to undo the brainwashing of the masks. She is completely successful with Nise, although Sniper Mask retains his suicide command and is forced to continue wearing his mask.
- Morality Pet: Seems to be this to Sniper Mask. In fact, it's inverted - he's the morality pet to her; the reason she was given such an overwhelming ability right from the start is that she's capable of being a remorseless killer, and only his influence held her back.
- Mysterious Waif: To Sniper Mask, as she is a Person Who Became Closer To God and he sets off on his own sidequest to help her.
- Precocious Crush: Sports one for Sniper Mask, despite being seemingly much younger than him.
- Support Party Member: She doesn't have much fighting skills, though her control of the rail gun makes her great for attacks from afar. After she dies and becomes a ghost, she continues in this role by helping Sniper Mask and Yuri, entering their minds and passing information.
- Voiced by: Koji Yusa (JP)
A strange doctor who claims to be a Person Who Became Closer To God. He has the power to control masks to do his will and intended to become a god by killing the others who were also closer to god.
- Arc Villain: He becomes this for a short period when he uses the Ein mask to kill another group. He leaves them alone when Kuon uses her rail gun and Yuri lies about it so he fears her enough to drop his intentions to become God.
- Entertainingly Wrong: Believes Yuri is a powerful God candidate based on valid assumptions. She eventually lives up to that reputation, but his reasoning at the time was far from correct.
- HeelFace Turn: Agrees to give up on becoming God and states he will treat people who are hurt in the Antenna Building.
- Know When to Fold 'Em: Recognizes he's outmatched and yields to Yuri's group.
- Redemption Equals Death: The very first time he joins Yuri's group on the front lines, he ends up biting it, although not without passing on his ability and final orders to Ein.
- Time Stands Still: Eventually discovers the ability to inflict this on masks for one second.
The Prophet / Hayami
A person who became closer to god with the capacity of knowing anything that is happening within a certain range. He allies himself with Yuri's party in order to have a chance of survival.
- Actually, I Am Him: Poses as a manipulated Emotionless Mask to assess Yuri's group but eventually gets outed before he can reveal himself.
- I Fight for the Strongest Side: Believes Yuri's group has the best shot at producing God and sides with them over Aikawa.
- Non-Action Guy: Unlike other God Candidates, he doesn't have any fighting skill, and therefore quits competing altogether by fighting by Yuri's side.
- There's No Place Like Home: Just wants to return and be reunited with his sister-in-law.
Yuri's beloved older brother and a leader to his own group. He is strong and dependable to the people he meets during the series, but he questions why, as he doesn't consider himself as much of a nice guy as others.
- Badass Normal: He hardly needed any power up to get to the level he is, being already a respected and strong fighter even before he actually got supernatural powers by becoming an Apostle.
- Berserk Button: A downplayed example, but he clearly hates his own name and can't handle being called uncool by others.
- Big Brother Instinct: Towards his sister, but slowly moves to basically all his comrades.
- Big Brother Worship: Inverted. He is more subtle about it, but he really looks up to Yuri. When a chapter focus on him and a guy he met, Rika mentions that he feels the same way towards his own older brother.
- Brainwashed and Crazy: Anyone who ends up Aikawa's Apostle becomes this, although he's the only successful victim. The others became empty husks due to being incapable. He instantly turns against Sniper Mask and Yuri, though he appears to be back to normal with Aikawa dead. In a rather strange example, he was brainwashed to not be brainwashed anymore.
- Combat Pragmatist: Arguably what makes Rika the most dangerous of the human survivors: he has a brain and he knows how to use it. Rika makes use of the mask's weaknesses in order to compensate for his human limits. This trait is what got Aikawa's attention in the first place.
- Connected All Along: It's implied he and Sniper Mask knew each other before the latter put on the mask. They used to be friends and compete over who is cooler.
- Dude In Distress: He gets kidnapped by Aikawa, both in order to call the others towards him and because Aikawa wants to try turning him into an Apostle.
- Hyper-Awareness: No minor detail goes past his attention. Rika first catches Aohara's Suspiciously Specific Denial and combined with the details that Yuri had given him, immediately figures out that the doctor probably has more than one mask at his control.
- Rika figures out that Yoshida is observing him during their conversation by waiting a while before picking up the phone, as Yoshida didn't start their discussion until he was sure the phone was in Rika's ear.
- The Leader: He has established a group to survive, and together they all follow his commands.
- Manchild: Temporarily becomes this when the Apostle-creation process initially seems to have failed.
- Manly Tears: Shed these when he saw Sniper Mask wearing a mask for the first time.
- That Man Is Dead: As an Apostle, he considers "Rika" dead. Although this distinction becomes blurred in that his personality doesn't change that much and he still responds to his name. It's just that the need to fulfill Aikawa's wishes supersedes any personal desires.
- The Smart Guy: He holds great knowledge of several things, from history, chemistry, military armament, and so on.
- The Strategist: He is capable of coming up with plans shortly facing a bad situation.
A game-loving guy who ends up in the game and tries to live by survival video-game rules.
- Eye Scream: Courtesy of a mask wielding a drill. One of Yoshida's masks ends up getting revenge for him.
- Fingore: A result of letting his guard down around the normally docile Emotionless Masks, unaware all of them just received the command to kill everyone.
- Genre Savvy: During his introduction, he quickly realizes he doesn't have Plot Armor because he is not protagonist material. After he meets Rika, he realizes that Yuri is likely the protagonist and decides to stick with him in his quest for her since at the very least they may have Plot Armor.
- Heroic Willpower: Manages to eventually fight off Juo's brainwashing.
A young boy that teams up with Yuri's group to survive.
Sniper Mask / Yuka Makoto / "The Second Judge"
A strange mask, who interacts a lot with Yuri and seems to be connected with Rika. He sports a rifle and has great skills at shooting at both long and close range.
- Affectionate Nickname:
- Mr. Mask, for Kuon.
- Yu-chan, for Rika.
- Amnesiac Hero: Hero being used just after his team up with Kuon. He has no recognition of anything before wearing the Mask, not even his own name, but he does eventually realizes that he was actually forced to wear the mask by Yahoo Kusakabe.
- Badass in Distress: His damaged mask occasionally asserts itself at inopportune times trying to either put him in hibernation or restore his original programming.
- Bait-and-Switch: Early chapter hinted that he would be Yuri's brother turned into a mask, but he is actually someone completely different and had faced Rika prior to meeting Yuri.
- Big Damn Villains: Sniper Mask pulls one when he shoots the Jerkass cop who threatens to rape Yuri.
- Cold Sniper: Sniper Mask. Lampshaded: Half his screentime consists of him worrying whether he is being cool or uncool.
- Connected All Along: It's implied he and Rika knew each other before the latter put on the mask. They used to be friends and compete over who is cooler. It's later revealed that they are brothers.
- HeelFace Turn: He starts off as just another antagonist, but his mask is damaged by a grenade tossed by Nise and his free will is partially restored. He is able to link up with Kuon, who cannot be attacked by the masks, and accompanies her long enough for her to finish deprogramming him.
- Improbable Aiming Skills: He is capable of shooting with such skill, the bullet ricochets around before hitting the target.
- Signature Move: To Yuri, his ricochet is this.
- Smoking Is Cool: A habit he kept even as a mindless mask.
- Take Up My Sword: Kuon gives him access to the rail guns after her death.
- The Unreveal:
- Around chapter 74, he takes off his mask to eat, but neither Kuon nor the reader are able to get a glimpse on what his face looks like. A flashback of himself has his face covered in shadows.
- Happens again in chapter 121, but this time, Yuri sees his face. She lets out he is quite handsome and has a scar beneath his left eye, but the viewer can't see.
- By the end of the story, his adult face is never revealed.

- Bullet Catch: He casually snatches one of Sniper Mask's bullets aimed at him.
- Crouching Moron, Hidden Badass: He appears most of the time to be a comic relief idiot who spouts non-sense, but when he is brought to the fight, he is implacable and can go toe-to-toe with a Guardian Angel.

- Pragmatic Villain: He orders his masks to not kill everyone, he leaves some behind to make even more masks.

- Eye Scream: At one point during his fight with Rika, he gets a pebble through his eye.
- Gender-Blender Name: His real name, Emiri, is a girlish name he was embarrassed about.

- Humans Are Bastards: He believed everyone is evil, and the masks are just bringing it to the surface. He can be gleefully evil because that's what he believes he was supposed to be.

- Voiced by: Shoya Chiba (JP)
Another Person Who Became Closer To God. He is capable of controlling up to five masks and is trying to help others using the masks he controls.
- Big Brother Worship: To Rika, similarly to Yuri, though it's because Rika would be his Senpai.
- Fatal Flaw: Despite his potential to be one of the most powerful God candidates, his cowardice and lack of confidence makes him overly reliant on others. His repeated failures and lack of acknowledgment also feed into his insecurities, making him an ideal victim for Demonic Possession by the Administrator.

- Never Found the Body: Goes missing after the final battle, but his consciousness stays around long enough to help Yuri one last time.

- The Faceless: A lot of them are never seen without their masks. Some are eventually unmasked, while Maid Mask is only seen from the mouth down in the manga (the anime shows her right eye). Later on certain controlled masks can remove their masks.
- The Heavy: The angels, although clearly being basically mooks, are still responsible for 70% of the danger of the world.
- Identity Amnesia: The ones who regain their free will or at least some form of self-control tend to have little recollection of their pasts before wearing their masks.
- Improbable Weapon User: A syringe, a log, and a screwdriver just to name a few.
- Hope Crusher: Their role in the game, embed the humans with so much despair that they will jump out of the buildings.

- Ax-Crazy: Particularly kill-happy even for an Angry mask. She says that she intends to bring down the filthy humans she couldn't in the real world and believes herself to be some sort of godsend.

Automatic Rifle Mask 2 / Floor 6

Dealer Mask / Floor 7
- Voiced by: Shizuka Ito (JP)
A Guardian Angel using the clothes of a dealer and a rifle.

- Politically Incorrect Villain: Besides being a mad man trying to become god, he is also a bit of a misogynist and calls women beings that can't hear anyone to the end when fighting Yuri.
The Supervisor / Faceless-kun
A program that seems to be managing the entire world.
- Affably Evil: Despite being the real force behind everything in the world, he's very nice, polite, and even puts nicknames on everyone.
- Ambiguously Evil: He is just a program meant to run this. A line from him even implies that someone else created him to run this world, this means that he may not really understand morality and when the chips are down, he makes decisions based on the rules, not morality, so it's hard to call him evil.
- Greater-Scope Villain: As the system that rules over the world. However, it doesn't seem malicious, just doing what it was created to do.
