Date & Aiba
Voiced by: Tarusuke Shingaki (Japanese), Greg Chun (English), D.C. Douglas (English, in his original body)
- "Heh, I'm used to "Psyncing." Part of the job."
The main protagonist and POV of the game, Kaname Date is a detective employed by ABIS (Advanced Brain Investigation Squad), a top-secret branch of the Tokyo Metropolitan Police Department. As one of ABIS's Psyners he can "psync" with suspects who are either unable or unwilling to cooperate during investigations to access their subconscious state - their "Somnium" - to uncover their minds' hidden secrets.
Six years prior to the game he lost both his memories and his left eye in an undisclosed incident that seems to be linked to the New Cyclops Killings he finds himself investigating in the present...
- Adorkable: In spite of his serious demeanour, he constantly makes terrible puns during his investigations and plays games with himself whenever Aiba is looking at him.
- Amnesiac Hero: Only remembers the last six years of his life. Because when his personality jumped to his current body, his memories didn't.
- He gets Ota to cooperate with the investigation by threatening to tell Iris that Ota is running multiple social media accounts to make it seem like he is defending A-Set from haters.
- He gets Moma to cooperate by threatening to expose him as an A-Set fanboy to his yakuza brethren.
- Chivalrous Pervert: Has a lecherous streak a mile wide while being good-hearted and protective toward others, as well as a good parental substitute for Mizuki.
- Cool Gun: The Evolver, a high-tech, collapsible pistol which fires a variety of trick bullets.
- Deadpan Snarker: He has his moments, and it gets worse when he is dealing with either Aiba or Mizuki.
- Did I Just Say That Out Loud?: He can communicate with Aiba without actually having to talk, but Date sometimes responds to her out loud, prompting many to think he's talking to himself.
- Eye Scream: He lost his left eye at some point prior to the game; it is replaced by Aiba.
- Improbable Aiming Skills: Most of the games QTE's involve some form of this, most notably Date ricochets a bullet to hit So from a thrown metal pipe.
- Last-Name Basis: Everyone either calls him Date or Mr. Date.
- Magic Plastic Surgery: After returning to his original self as Falco/Hayato Yagyu, this trope is actually just an excuse that everyone uses to explain why his face looks different to those who don't know his true identity and only knew him with Saito's face.
- Male Gaze:
- At the Lemniscate building, Date catches a glance of the receptionist's Gag Boobs. Continuing to examine her will cause Date to increasingly focus on her chest.
- Examining the "Mermaid" Amane Doi using X-Ray will result in Date admiring her hip structure.
- Overprotective Dad: Despite not being her actual father he occasionally acts like this in regards to Mizuki, such as being very unhappy upon hearing that she's friends with Ota or being inwardly relieved when she says she hasn't kissed anyone yet.
- Parental Substitute: Has been one to Mizuki for four years. And in the Golden Ending he officially adopts her.
- Pungeon Master: Constantly inspecting the scenery brings this side of him, particularly when it comes to the Lemniscate sofas.
- Screw the Rules, I'm Doing What's Right!: In Mizuki's route, he goes against Boss's orders and tries to apprehend So Sejima for himself.
- Screw This, I'm Outta Here!: There's a joke ending you can get where Date decides to resign from the police force and skip town with Ritsuko, and they live happily ever after in Shizuoka.
- Super Speed: Hearing the words "porno mag" briefly allows Date to move quickly enough to dodge bullets in an effort to reach it.
- That Man Is Dead: In the true ending, when Date is back in his original body, he completely discards his past as Hayato Yagyu/Falco and embraces his "fake" identity as Kaname Date.Hitomi: Mr. Falco? It is you, Falco, right?Date: You shouldn't call me that. I am Kaname Date. MPD, special investigation team ABIS.

The artificial intelligence that resides inside of Date's artificial left eye. Aiba is a powerful asset during Date's investigations, granting him abilities such as X-ray and infrared vision as well as serving as a wireless communicator, database, hacking tool, and more. During Psyncing sessions she takes on the form of a young woman to directly explore and interact with the subject's Somnium.
- A Form You Are Comfortable With: During Somniums and when projecting herself in Augmented Reality, she takes on a human form which she claims is based on Date's preferences.
- Adorkable: She can be really silly during Somniums. Outside of them, she gets really giddy whenever she spots an insect.Aiba: Date! Look! A cricket! Chirp, chirp!
- Agent Scully: On the plot branches where Date starts to delve into more conspiratorial or supernatural thinking, Aiba remains a constant voice of skepticism. She is usually right about this, though alternate universes do seem to be real to some extent.
- Awesomeness by Analysis: During action sequences, Aiba can near-instantly analyze every possibility to find a way for Date to come out victorious against insurmountable odds. Most of these somehow involve porno mags, real or fake. She can even predict when and where lightning will strike, how pieces of shrapnel will ricochet, and how other people will act, among other things.
- Benevolent A.I.: Although she and Date often have their disagreements, Aiba is overall a trustworthy partner who helps out a lot in their police duties.
- Bilingual Bonus: In her Appendix profile, on of the things she likes is listed as "1010000011110101". Translated to decimal it reads "41205", which later on you find out means 'Date'.
- Deadpan Snarker: She can certainly be snarky when she wants to. Apparently her personality was designed that way by Pewter, much to Date's annoyance.Date (after Aiba surprisingly popped out of Date's eye socket) : Why did you come out?Aiba: I haven't been getting a lot of exercise lately.
- Disney Death: In the Resolution route, Aiba self-destructs to defeat Saito after her backup data had been deleted, causing her to be effectively killed off. However, it turns out that her data had secretly been uploaded to cloud servers, and after several months ABIS had managed to piece it back together, bringing her back to life.
- Heroic Sacrifice: In the Resolution route, Aiba uses her self-destruct command to take out Saito. However, as her data storage is being destroyed, the act renders her dead and she gives her life to save Date and the others. Until the the true ending that is.
- Living Lie Detector: Aiba's thermal imaging ability, on top of allowing her and Date to detect the temperature of objects, can also detect the subtle change in body temperature that a person experiences when telling a lie. However, this is not guaranteed to work on very experienced liars such as politicians.
- Night-Vision Goggles: Aiba has a night vision mode, allowing Date to see in the dark.
- Not So Above It All: Outside of Psyncing she is usually calm, rational, and snarky...until she spots an insect and becomes as giddy as a small child.
- Not So Stoic: At one point, she is tasked with performing an impersonation over the phone. When asked if she's nervous, she claims that, as an AI, she's not prone to "nervous breakdowns and mistakes" like Date. She then makes the call, only to become a nervous wreck when the call is actually answered.
- Punny Name:
- She is an A.I. ball, but when AI is pronounced as a single word, it makes her name phonetically identical to "eyeball".
- In the Japanese version, she is called "Aibou" (アイボゥ), which means "partner". Phonetically, it almost sounds the same as how one would pronounce "eyeball".
- Taking the Bullet: Non-fatal example. When So shoots Date on Mizuki's route, Aiba inadvertently saves him due to him being shot in the eye that she resides in. As all of her data is stored remotely, she's eventually restored. She treats it as this trope, but Date reminds her it was just a coincidence.
- Three Laws-Compliant: She frequently threatens to self-destruct in Date's eye socket, but eventually admits that she cannot do so without an outside command because self-preservation is part of her programming thanks to the Three Laws.
- Tsundere: She clearly cares about Date in spite of his constant jabs at him, but when any of her attempts at trying to get his affection are mentioned, she immediately denies them.
- Voice Changeling: Is able to perfectly imitate people's voices, including (at least) Date's and Shoko's.
- We Can Rebuild Him: After her apparent demise during the final battle with Saito, the true ending reveals that the Wadjet System was uploading traces of Aiba's data into cloud storages around the world, which is how she is remade into her former glory.
- X-Ray Vision: One of Aiba's abilities. She can see through objects, and inside people's bodies, though it doesn't actually allow Date to see people naked.
Boss / Shizue Kuranushi
Voiced by: Yuko Kaida (Japanese), Allegra Clark (English)
The head of ABIS and thus Date's, well, boss. Boss is a woman with a playful, flirtatious personality yet she can also be very forceful and stern when the situation calls for it. She likes to maintain a festive atmosphere around ABIS's offices.
- Blackmail: Not above using it to get what she needs. Early in the game, she blackmails the medical director of the hospital Mizuki is staying at in order to get her released, and near the very end, it's revealed that not only did she blackmail So into handing Saito over to the police six years ago, she also pulled some strings with HQ to pay for Iris' surgery.
- Killed Offscreen: In Ota's route, she's killed by Saito after he swaps bodies with her. You find out about her death (and witness it via video) in the Annihilation route.
- Lovable Sex Maniac: She's constantly making double entendres, to the point that she can make the act of playing darts sound sexual.
- Ms. Fanservice: A beautiful woman who dresses in clothes that show off her legs and ample cleavage, and occasionally has some playful dominatrix-like banter.
- Older Than They Look: Looks about as the same age as Date, but she is in her 40s.
- Only Known by Their Nickname: While it is possible to find out her real name in-game, those who work for her only call her "Boss", and Date doesn't even know her name at the start.
- Reasonable Authority Figure: Though she does sometimes draw the line to keep Date from poking his nose into sensitive matters, she is generally supportive toward her subordinates.
- Red Herring:
- In the routes where Date and Iris are ambushed by mercenaries, Date briefly suspects that Boss tipped them off, since she was one of the only people that knew where they were going (but later it turns out that it was Pewter who set up the ambush, since he was the contact that Date was going to meet, and was tipped off by Mama).
- Also, in the Annihilation route, a video of her killing So Sejima is found just before the route locks up. It transpires that's not really Boss but Saito in her body.
- Also again, a little earlier in the Annihilation route, Date sees her in #89's Somnium, bursting into Hitomi's house alongside Rohan Kumakura. In reality, she was there as The Cavalry.
Pewter / Futa Amanoma
Voiced by: Hiroki Goto (Japanese), Sean Chiplock (English)
ABIS's resident scientist who is responsible for inventing and operating the Psync machine used to access subjects' Somniums. He also invented Date's AI partner Aiba.
- Heel Realization: In the true ending, after defeating Saito Sejima, Pewter gives himself up and decides to serve his time for his involvement with Saito. He tells Date that Kagami is his handler and it's through his permission that they are able to talk to each other.
- Lemony Narrator: He writes all of the descriptions in the Appendix, and many of them have this style to them.
- Love Makes You Evil: On the routes where Renju doesn't die, Saito uses Pewter's status as Renju's lover to betray the police for him.
- The Smart Guy: Invented all of the sci-fi machinery that Date uses.
- Yaoi Fanboy: His file cabinets are packed with BL novels and manga.
Voiced by: Brad Venable (English)
A forensic investigator with Tokyo MPD that Date always encounters working the crime scene...and can never remember his name.
- Butt-Monkey: Every time you meet with him, Date never remembers his name, and when he finally does, Kagami gets emotional, prompting Date to call him a weirdo.
- The Faceless: Courtesy of his hat and surgeon's mask. The in-game appendix claims that he's quite cute without it.
- Odd Friendship: Name shannanigans aside, he and Date seem to get along well.
- "Shaggy Dog" Story: The one time Date finally remembers his name during Mizuki's route he immediately forgets it again and refers to him as "Kaniza" for the remainder of the route.
Voiced by: Kenji Hamada (Japanese), Chris Hackney (English)
- Abusive Parents: Emotionally neglectful as he put running his company above raising his daughter and threw up his hands and refused to take a stand and intervene when his wife became physically abusive. When Date hears of this he tells Renju to his face that he thinks he and Shoko are terrible parents. Though, unlike his ex-wife, he does possess enough self awareness to realize that he's no good at raising a child and entrusts Date with Mizuki. It also doesn't help that he was also trying to help support Iris.
- Asshole Victim: Not to quite the same extent as his wife (he at least does have people who care about him who aren't directly related to him), but most of his characterization focuses on him being a terrible parent and a shady businessman.
- Bi the Way: Sometime after he and Shoko divorced, Pewter became his new lover.
- Dead All Along: While he's the prime suspect for Shoko's murder, in most routes his is the next corpse found after hers. And even in the routes where it seems he survived, this is actually Saito. Renju's personality was murdered in Shoko's body.
- Posthumous Character: While his body is physically alive at some points, his mind, in Shoko's body, was actually killed shortly before the game began.
Voiced by: Yuu Kobayashi (Japanese), Dorothy Elias Fahn (English)
Mizuki's mother and Renju's ex-wife. The plot is triggered by the discovery of her body tied to a merry-go-round at the abandoned Bloom Park, stabbed to death with her left eye gouged out pre-mortem.
- Abusive Parents: She often found no way to deal with Mizuki's behavior other than hitting her. Date calls her out on this during a flashback.
- Asshole Victim: An absolutely horrible mother who also ran an investment fraud operation with help from the local yakuza? It's easy to see why so few people actually mourn her passing.
- Freudian Excuse: According to Renju, Shoko's own mother never showed her any form of maternal affection, so she didn't know how to love her own daughter.
- Never My Fault: Refused to take any responsibility for abusing her daughter, instead blaming it all on Mizuki for being "abnormal", and for making her look like the bad guy.
- Posthumous Character: The game starts with her death. It turns out that this is only her body; her personality died in Rohan Kumakura's body a year beforehand.
Voiced by: Tomoyo Kurosawa (Japanese), Corina Boettger (English)
Renju and Shoko's twelve-year-old daughter who's been living with Date for four years following her parents' divorce. Normally unusually perceptive, mature, and physically strong for her age the discovery of her mother's dead body at Bloom Park renders her traumatized and mute at the start of the game.
- Abusive Parents: Shoko was utterly unfit to be a mother, and Renju prioritized managing his business and Iris's well being over taking care of Mizuki. This led to Date taking her in.
- And Now for Someone Completely Different: Near the end of her route, you play as her after Date falls in a coma, and have to go into his Somnium to try to wake him up.
- Better Manhandle the Murder Weapon: When she is found inside the merry-go-round, she is holding a bloody icepick. Considering how Shoko was stabbed to death with an icepick, it doesn't really look good for her. Once she regains her speech, she explains that she couldn't bear to see the pick sticking out of her mother's eye socket, so she pulled it out without thinking.
- Big Damn Heroes: In the Resolution route, she charges at Saito right he's about to kill Iris in front of Date.
- Bratty Half-Pint: Once she starts talking again, she immediately turns to sass as her default mode. Justified by her being twelve years old and dealing with a lot of family drama, even before the horrific events of the game.
- Break the Cutie: Seeing her mother's corpse left her so traumatized, she became temporarily mute. It happens again on the Annihilation route after Iris and Ota are killed; after this happens, she does not speak for the entire rest of the route.
- The Cavalry: One-third of the cavalry, along with Ota and Moma.
- Charles Atlas Superpower: Mizuki claims to be strong, and that's really not an exaggeration. She has strength no child of her body, build, and size could ever have; it's simply beyond human limits. She easily bench presses 100kg like it is nothing, jumps several times her own height, kicks a whole tall tree down with ease, and during a somnium she can easily lift furniture as if they were made of paper. While somnium worlds do not necessarily reflect reality, Mizuki acts as if she really has done that around the house before. This strength of hers simply exists and Date has just trained Mizuki to properly use it, no supernatural background is given.
- Complaining About Rescues They Don't Like: At one point in her own route, she gets attacked by Sejima's men and left bound and gagged inside one of the hollow speakers in Date's apartment. Once Date finds her, the first thing Mizuki does is chastise him for both taking too long and ripping the tape off her mouth so forcefully.
- Girls Love Stuffed Animals: She has a plush bunny toy called Adorabbit. Initially, she didn't like it at first for it's uncanny appearance, but she soon grew to like it and even introduced it to Iris, who also likes it too. Mizuki received the toy as a birthday gift from Date, who didn't know what she wanted and just bought the toy for her instead.
- It's All My Fault: She views herself responsible for her parents' abuse, divorce, and subsequent murders, convinced that if she had only been a "good girl" none of that would've happened.
- Little Miss Snarker: Mizuki is often very sarcastic and blunt with her words, especially towards Date (to be fair, Date is also pretty snarky towards her).
- Little Miss Badass: Mizuki is much stronger than her size and frame would suggest. In one route, she joins Date in fighting off So Sejima's armed bodyguards and takes out half of them with a metal pipe. In another, she does the same with a large number of heavily armed mercenaries.
- Pint-Sized Powerhouse: She has practically superhuman strength, as demonstrated by her bench pressing 220 pounds without breaking a sweat and holding her own against armed bodyguards and mercenaries.
- Pipe Pain: Mizuki's strange obsession with pipes also extends to using them in combat, as shown during the raid on So Sejima's mansion, where she defeats several grown men armed with guns by hitting them with her pipe. It helps that she's also a Pint-Sized Powerhouse.
- True Companions: She fully trusts Date, Iris, and Ota as her friends.
- Tsundere: She constantly argues with Date, calls her names and doesn't give him any respect. Despite this, as her route reveals, she is very dependent on Date due to her rocky relationship with her family, and she sees him as more of a family member than her parents. Ironically, Mizuki calls Date this trope in her ending, which she isn't exactly wrong about either. And while she likes to tease Date and Ota, she's very warm and friendly when she's together with Iris.
- You Gotta Have Blue Hair: Just like her mother.
- Younger Than They Look: You wouldn't be able to guess that she's meant to be half of Ota's age if you'd put their character designs beside each other with no other context.

An aspiring light novel writer and big-time fan of Iris who's often found hanging around either the Lemniscate lobby or the Sunfish Pocket Maid Cafe. His infatuation with Iris, whom he calls "Tesa", has led him to declare that he's her thrall and protector, causing Date to take almost an immediate dislike to him. He claims to be a light novel writer but hasn't actually published anything.
- Bad Liar: To the point Date doesn't even need his thermal vision.
- Bothering by the Book: He has an uncanny knowledge of law and the police system, which aggravates Date immediately.
- The Cavalry: One-third of the cavalry, along with Mizuki and Moma.
- Cowardly Lion: While at first he abandons Mizuki in Bloom Park after finding Shoko's body, later on he shows himself capable of acting during life or death situations such as driving an armored vehicle through a bunch of armed mercenaries in Iris's route and saving Iris and injuring the New Cyclops Killer during his and Mizuki's ending (though the injury was mostly an accident)
- He also attacks Date on several different routes just to protect Iris, even if that meant getting in trouble with the MPD.
- Half the Man He Used to Be: During the Annihilation route, he ends up getting sawed in half by the ice-cutting machine.
- Hidden Depths: According to Mizuki, Ota is the kind of otaku with social skills.
- It's All My Fault: On his route, he blames himself for Mayumi's dementia and Takero's death from overwork, especially the former as he initially thought it was some kind of sick joke Mayumi was playing on him.
- Jerk with a Heart of Gold: He's very uncooperative with Date and can be very harsh on his own mother, but he also legitametly cares about his friends, and grows out his more negative tendencies as the story continues.
- Loony Fan: Of A-set. To the point where he'll defend her on To-Witter from... sockpuppet accounts that he also controls.
- Older Than They Look: He's 24 years old, but you'd be forgiven for thinking he's much younger given his height and somewhat cartoony appearance.
- Otaku: Ota's definitely this, from his anime and video game references, to buying Tesa figures, to even wearing a Tokusatsu belt on his outfit.
- Spoiled Brat: Mayumi spoiled him greatly as a kid.
- Yank the Dog's Chain: In his route, he saves Iris's life and Date thinks he has a chance with her. But from other routes you know that it is really So Sejima in her body, and Iris was already dead.
Voiced by: Toshiko Sawada (Japanese), Philece Sampler (English)
Ota's kindly yet scatterbrained mother who runs the Matsushita Diner located near Bloom Park. She has a noted sense of dislike for Iris, believing her to be a witch who's enchanted Ota into spending all of his time and money on her.
- Failure-to-Save Murder: In the Annihilation route, she blames Date for Ota's death.
- Miniature Senior Citizens: Not quite a senior citizen at 54 years old, but she's around the same height as her son.
- Scatterbrained Senior: She suffers from dementia.
- Taking the Heat: On Ota's route, she attempts to confess to being the Cyclops Killer in order to protect Ota from suspicion. Date is quickly able to poke holes in her testimony, however.
- Took a Level in Kindness: While she is generally sweet, she finally apologizes to Iris in the true ending and seems to have grown a liking to her once she gets to know Iris.
Voiced by: David Lodge (English)
- Dead All Along: It's eventually revealed that he died years before the events of the game, of a heart attack.
- Gonk: While Ota and Mayumi stand out by virtue of being rather heavyset, Takero stands out because he's tall and thin with beady eyes.
- Good Parents: Despite his appearance, he's still a good father to Ota and a good husband to Mayumi.
Voiced by: Naomi Kusumi (Japanese), John De Mita (English)
A local congressman. So Sejima is a man who values his wealth and status above all else and is above no amount of coercion to bury anything that threatens them. Most notably he has ties to the criminal underworld via the Kumakura Family.
- Body Snatcher: In Mizuki's and Ota's routes he ends up in Iris's body. Also counts as Familial Body Snatcher, but not by his choice.
- Boom, Headshot!: How he dies on Mizuki's route, Ota's route (presumably) and the Annihilation route. In Mizuki's route it's Date that kills him; in the others, it's Saito in Boss's body doing this before cutting him up into pieces. But it is not realy him, depending on the route it is either Saito or Boss in his body respectively.
- Bothering by the Book: Not to the extent that Ota does it, but he does this to Date on occasion. Given he's a politician, it's at least justified.
- Half the Man He Used to Be: In Ota's route and the Annihilation route, he ends up dismembered and stuffed into an ornamental jar. Or rather, his body is. In the Annihilation route he is cut in half while in Iris's body.
- It's All My Fault: In the true ending, he blames himself for how Saito turned out.
- Karma Houdini: While he does lose his position as a congressman before the epilogue, he faces no repercussions for his past criminal actions. He's specifically aware that in Japan the statue of limitations for interfering with a body is only three years, and since he didn't actually kill Manaka, there's nothing the police can do about it. By the time of the epilogue, he's planning on moving to another country.
- Red Herring:
- In his Somnium, you're led to believe that he's the nondescript blue figure stabbing Iris to death. In reality, not only is that not him, it wasn't even Iris being stabbed; the only reason she appeared in it was due to her looking similar to Manaka.
- More generally, the narrative almost always makes him out to look more evil than he really is, and frequently sets him up as the Big Bad. In reality, his only plot-relevant misdeed when not a victim of a Body Snatcher is covering up his son's first murder, which, as he notes, isn't even a crime in Japan when it's done to protect a relative.
- Screw the Rules, I Have Connections!: As a congressman, he has a lot of important people in his pocket, including the higher-ups in the police department.

- The Cavalry: One-third of the cavalry, along with Ota and Mizuki.
- Chivalrous Pervert: He swears to do anything for Iris, but on three separate occasions he asks Date to ask her for something. The first time is just a handshake, which isn't so bad, but the second time he asks to see her panties (which Date duly asks and gets slapped for) and the third time he wants Marshmallow Hell. He ends up getting it... from an unconscious, male yakuza underling instead.
- Jerk with a Heart of Gold: Despite being a mob boss, Moma is actually a huge A-set fan, swears on his life that the family is going clean for Iris, and acts as part of The Cavalry in the Iris and Resolution routes.
- Out of Focus: On the Mizuki, Ota, and Annihilation routes, he fades into the background almost immediately after his introduction scene, which is jarring given how big of a role he plays in other routes.
- Red Baron: Calls himself "War Horse" while introducing himself to Date... which is actually what the kanji in his name mean.
- Unmanly Secret: Moma is secretly a huge A-set fan, but has to hide it since being an idol fanboy isn't exactly good for a badass yakuza's image. In the Golden Ending, he finally reveals his love for A-set to his gang, and forces them to watch her videos until they're just as obsessed as he is.
- Weapon of Choice: He often uses a M1 rifle. He threatens Date with it a few times, and gets to use it during the raid to rescue Iris.

- The Dragon: To Saito Sejima.
- Driven to Suicide: Jumped off a building before the game started. This was actually Shoko Nadami, having been a subject of Grand Theft Me from Saito Sejima in Rohan's body.
- Faux Affably Evil: From what is told in flashbacks, Rohan seemed civil enough back when he was alive, in spite of his his reputation as a sadist and in the present, he acts jokingly during his interrogation with Date while in #89's body. However, he was still helping Saito, who was a sadistic serial killer with the Original Cyclops Killings just for his own morbid desire for women's eyes. He also had no qualms killing both Hitomi and Iris, even when the latter was just 12 years old.
- Nightmare Fetishist: Women's eyes, specifically their right eyes. His desire to possess them lead to the Original Cyclops Killings, and it's speculated by Moma and Aiba that his fascination with them was driven by a cognitive disorder developed after suffering a savage beating to the left side of his head decades ago.
- Posthumous Character: Subverted. The one who commited suicide a year ago was Shoko while in Rohan's body. Rohan has actually been imprisoned while inside Inmate #89's body.
- Torture Technician: Torture is listed as one of his "skills" on his profile and Moma relates a story of him skinning a guy with a vegetable peeler.
- You Have Outlived Your Usefulness: After Saito (in Renju) helps break Rohan (in #89) out of custody, Saito forces a body swap using the prototype Psync machine, landing Rohan in Renju's body - which was moments away from expiring from internal injuries.

The second of Moma's two yakuza lackeys.
- Back-Alley Doctor: Serves as this for the Kumakura Clan. It's also implied that he was the doctor Renju brought Hitomi to after Rohan shot her.
- Beta Couple: Him and Hanayo; during the true ending, she mentions that she'll be changing her last name to "Yogano" the following month.
- BFG: He attempts to kill Date with a minigun in one of the routes.
- No Name Given: Is only referred to as "Yakuza B" in-game; his actual name can only be found in the File section.
- Punny Name: "Dokuta" sounds like "Doctor".

A nameless inmate serving a life sentence for multiple murder counts. He claims to know the true identity of the New Cyclops Killer.
- Badass Baritone
- Exact Words: Says he's one of the two original Cyclops Killers. He never says which one he is. Turns out he's Rohan Kumakura inhabiting Falco's body. He also delivers the backstory of Falco ("Let's call him F") in third person, because that's not him either.
- No Name Given: Claims to have forgotten it.
- Walking Spoiler: He's Rohan Kumakura in Kaname Date (or rather, Hayato Yagyu)'s original body.
A-set / Iris Sagan

- "Good evening, good morning, and hello! It's the brand-new star of the net world, Tesa, also known as A-set, you bet!"
An internet idol and videogame streamer working for Renju's company; Lemniscate. She's an energetic young girl who's friends with both Mizuki and Ota. In spite of seemingly having nothing to do with the case at hand, she voluntarily gets involved with Date's investigation, much to his annoyance.
- Animal-Eared Headband: Never seen without her cat-like headband, except during flashbacks. Near the very end, she reveals that she actually wears it for a purpose; it's meant to keep her brain cancer from spreading.
- Beware the Silly Ones: In spite of her bubbly personality , she's more than willing to blackmail Date as soon as they met. She seems to get even shadier in the route on the left but it's not really Iris by that point, but Saito pretending to be her.
- Cloudcuckoolander: Deconstructed. She acts like one but her brain tumor is apparently causing this.
- Conspiracy Theorist: She holds a delusion of an organization known as Naixatloz targeting her for uncovering their secret project regarding the spread of A.I. across the universe. Her Somnium's residual effect on Date's psyche might cause him to believe the same delusion if he continually has Aiba follow her instructions.
- Gamer Chick: She's a video game streamer on top of her musical career. The game that is mentioned the most is ShovelForge (a Bland-Name Product version of Minecraft), and her Somnium is based on that game.
- Genki Girl: She fits this trope like a glove, especially when she's filming her videos.
- Girlish Pigtails: Both her younger and current selves sport variants of this hairstyle.
- Girls Love Stuffed Animals: Mizuki introduced the Adorabbit toy to Iris and she really liked it, prompting her to buy Adorabbit merchandise.
- Half the Man He Used to Be: The Annihilation route sees her end up this way courtesy of an ice-cutting machine. Her body, that it. She was really strangled in Renju's body earlier.
- Hidden Depths: She shows a lot of interest in conspiracy theories and phenomena such as the Mandela Effect. She also knows a lot about Greek and Egyptian mythology.
- Like Brother and Sister: This is how she views her relationship with Ota. Though Ota likes to think otherwise, he once describes Iris as "a sister that isn't blood related." Though it's questionable.
- Ill Girl: Is suffering from a terminal brain cancer, which she dies of at the end of her route.
- The Load: She purposefully acts like this to Date at first by interfering his investigations with ShovelForge requests or asking him out on a date. (She even blackmails him just to take her to the crime scene at the beginning of the game at one point.)
- In-Series Nickname: Her fans call her "Tesa", which is "A-set" spelled backwards.
- Nice Girl: There doesn't seem to be one mean bone in this girl's body.
- Secretly Dying: She hasn't told anyone about her brain cancer, and makes excuses or tries to change the subject whenever her friends notice symptoms.
- Shipper on Deck: Isn't shy about hinting that she wants her mother, Hitomi, to be together with her 'Uncle', Falco, aka. the actual Kaname Date.

- You Gotta Have Blue Hair: Her hair is pink.
- Your Days Are Numbered: Due to her brain cancer, she isn't expected to live to the end of the year. She ends up dead at the end of her route, though in the Golden Ending she finally receives the extremely expensive nanosurgery treatment that can save her thanks to Boss's help.

Iris's mother and Mizuki's teacher. She seems to have a connection with Date, as she appears unconscious in one of Date's dreams at the start of the game.
- Blackmail: She tries to use Manaka's body to blackmail So into giving up enough money for Iris's surgery, using Manaka's corpse. It successfully rattles him; unfortunately before she can hide the body again Date arrives.

- Ship Tease: With Date, especially after he's back in his original body.
- Taking the Bullet: The nerves in her right shoulder were destroyed, rendering that arm unusable, due to her jumping in front of a bullet intended for her then-love interest. More context is added to the scene as the game goes along, revealing that Rohan Kumakura and Boss broke into her house and attempted to kill Falco...except Falco and Rohan had swapped minds, and Rohan was planning to use Falco's body to carry out the hit that he ordered on Hitomi and Iris. Hitomi had no idea what was going on, and thus took a bullet intended for her would-be killer.
- Unexplained Recovery: Rare non death example. Her right arm is able to move again at the Dance Party Ending that happens at one of the endings despite her arm getting shot.
All of these characters are Walking Spoilers. Spoilers are unmarked in these folders.
Rohan Kumakura & Saito SejimaA term used to refer to the perpetrator of the "Original Cyclops Killings" six years ago, in order to differentiate them from the New Cyclops Killer. In truth, there is no single "Original Cyclops Killer": the murders were the result of collaboration between Saito Sejima (who could only feel pleasure from killing) and Rohan Kumakura (who was obsessed with collecting women's eyes).

- Bad People Abuse Animals: He mentions that as a child, he first started by killing animals before he eventually grew bored and sought the bigger thrill of murdering other people.
- Big Bad: The only people intentionally murdered in the game are killed by Saito. He is both the New and Original Cyclops Killers.
- Body Surf: Prior to the game, he had swapped himself with Falco in Rohan Kumakura's body, then five years later swapped into Shoko Nadami, and just before the game starts, into Renju Okiura.

- Didn't See That Coming: Aiba's presence in Date's/his eye socket leads to his death in Mizuki's route and the Resolution route. Even at the end of the Annihilation route, where Saito's plan has gone otherwise off as intended and he's reclaimed his body and killed most of the main cast, his moment of triumph is unceremoniously cut off by Aiba shocking him unconscious.

- Jerkass: He's very unpleasant and rude.
- Slasher Smile: Is really good at making evil expressions, no matter whose body he's in.
- Start of Darkness: Not that he was a good person to begin with, but killing Manaka started him down a much, much darker path.

- Wide Eyes and Shrunken Irises: His eyes are like this combined with his Slasher Smile when he gets gleefully excited.
- Your Head Asplode: In the Resolution route, thanks to Aiba self-destructing in his eye socket.

- Love Redeems: Tried to reform after falling in love, but Rohan Kumakura insisted he take one last job.

- That Man Is Dead: After recovering his original body and memories, he does his best to put his past as "Falco" to rest so he can be a better person.
- Trapped in Villainy: When Rohan tracked him down over his extrajudicial killings, he forced Hayato to start killing for the Kumakuras.

- Ambiguous Gender: Her profile lists "Gender neutral" under "Sex", though the game uses female pronouns for her.
- Knowledge Broker: The primary reason Date comes to her bar so often.
- Transgender: When she's first introduced in the right-hand-side routes, Date mentions that she was born with a male body; her profile lists her as gender-neutral, but she uses female pronouns and (at least whenever we see her) presents as female.
Iris's real mother.
- In the Back: How she died; Saito stabbed her in the back repeatedly.
- No Accounting for Taste: She honestly loved Sejima with all her heart yet throughout the entire game Sejima is never seen doing anything remotely admirable nor the man himself ever has a moment where he at least could say one good thing about Manaka, making one wonder how a seemly good natured girl like Manaka could ever truly fall for Sejima, even her good friends Renju and Hitomi trying to steer her away from him didn't work out.
- Posthumous Character: She was murdered 18 years before the start of the game.
- Walking Spoiler: Iris' biological mother, and the true identity of the corpse Date sees in Mizuki's somnium and in the cold storage warehouse.
- All Men Are Perverts: When fought, almost all strategies involve distracting them with porno magazines or underwear.
- Drowning My Sorrows: One of the guards can be found at Marble at the end of the Resolution Route
- Guns For Hire: It's implied that they are the same mercenaries that Date keeps encountering.
- Imperial Stormtrooper Marksmanship Academy: You might as well forget the fact that they're armed during the QTE's.
- No Name Given: None of the bodyguards are given names, not even in the Persons section of the File menu.
- Not So Stoic: Date can attempt to distract one of them by saying things like "Look! A grandma!" and none of them work until he tries "Look! A porno mag at your feet!"
- Leaning on the Fourth Wall: She's apparently in an association of nurse actors (as in actors who happen to also be nurses, not people acting as nurses). During a scene in the true ending, she mentions that she's happy because she initially just had a bit part in her latest role, only saying a few lines near the beginning, but now she's getting a few lines at the end too. Fittingly enough, she only appears near the beginning of Iris' route and during the true ending.

- Fanservice Extra: A receptionist with Gag Boobs who's never seen outside of Lemniscate, barring a single phone call to Date, and the ending.

- Hartman Hips: Date can use his X-ray vision to check out her body this way, showing he's got a thing for girls like that, much to Aiba's frustration.
- Punny Name: It is an anagram of maameido, the Japanese spelling of the word mermaid, and she works at a mermaid-themed maid cafe.
- You Gotta Have Blue Hair
