"Yeah! I just solved the SHIT out of that puzzle!"
An ordinary college student kidnapped from his car on Christmas Eve, and the protagonist of the game. He has a tendency to make risqué jokes at inappropriate times and is easily swayed by his emotions, which makes him a poor choice for a game about trust and betrayal.The Sigma playing the Nonary Game is actually his 22-year-old consciousness inhabiting the body of his 67-year-old self. The purpose of the AB Project was to swap their minds, sending the mind of the older Sigma into the past so that he would have a chance to Set Right What Once Went Wrong.
Actor Allusion: Vincent Brooks from the puzzle game Catherine says a similar line to Sigma's above quote(albeit in the future tense). Both characters are voiced by Troy Baker.
Artificial Limbs: Possesses a set of these due to the Mars mission test site incident. Unlike Snake's purely prosthetic arm from the first game, Sigma's limbs are fully functioning cybernetic replacements covered in synthetic tissue (which, sadly, means that the bracelet will work quite properly with them.)
Badass Grandpa: Think over everything he did in the game reminding yourself he has the body of a 67 year old man.
Big Damn Heroes: Does this in more than one timeline for both Alice and Quark, as they are the first to show symptoms of Radical-6 in almost every route.
Butt Monkey: In most bad endings when he recieves 9 BP, he is NEVER allowed to leave. He is also the only player who is alive to see his BP drop below 0 in certain timelines.
Chivalrous Pervert: He can get excessively creepy with the girls sometimes, but he definitely one of the more compassionate of the cast.
Cursed with Awesome: According to the secret files the reason Sigma talks in cat puns when anything related to a cat is involved is that he was cursed by a magical cat when he was younger.
Determinator: He will not let anything stop him from his goal, which is particularly noticeable on the two paths where his bracelet is triggered. In each path, he manages to save at least one person's life and get some critical information while under the influence of a drug that knocks most people out instantly. And in the events prior to the game, he spent 45 years researching genetic engineering, quantum computing, artificial intelligence, and mechanical engineering to set up the Nonary Game, all with the purpose of undoing the outbreak of the Radical-6 virus.
Dirty Old Man: Comes across as one to many of the other characters in game, thanks to him being literally a 22 year old in a 67 year old body.
Failed a Spot Check: He never once realizes that he has a futuristic eyepatch in place of an eye, or that his voice has changed, or that with the exception of his arms he is a sixty-seven-year-old man.
Failure Hero: The main objective of the game is to reverse this.
First-Person Ghost: Aside from flashbacks, we never see his face. Nor do we get to hear his voice. This is intentional, in order to hide from the player his actual appearance, since it is a massive reveal.
Freak Out: In his route, the Game Over that occurs if you find Alice dead ends with him screaming his lungs out followed by a fade to black and the narration "when I came to, I was floating in a field of nothingness". While this seems to imply his death, it is actually him jumping back in time due to the stress as seeing this bad ending is required to save Alice's life.
A similar thing happens if you get the Game Over from betraying in round 2.
Go Mad from the Revelation: In his route's main Game Over, he wakes up in the infirmary to see his hand has been cut off... and then he sees what his arm looks like as a cross-section. Cue the Freak Out.
Handsome Lech: He has a muscular build and he's good looking enough, but for some reason, the girls in the game act with revulsion whenever he makes a pass at them. Averted the entire time, since Sigma spent the entire game possessing his 67 year old body with wild gray hair and a right green eyeglass.
Heroic Sacrifice: Allows Dio to bring his BP to negative in exchange for the Axelavir needed to save Quark, though he survives the injection.
In the K Path, Sigma uses the Neostigmine on Phi rather than himself.
Meaningful Name: It's not brought up in game, but Sigma is the mathematical symbol used in Summation: the adding together of many variations of an expression. Sigma goes through many iterations of the Nonary game and his experiences must be summed together to reach the solution.
"Well, I'm not Superman, that's for sure. And I'm not Batman, or Spiderman, or Aquaman, or a merman, or a wolfman. I'm not a brahman, or common, or ramen. I'm not a caiman either, so you don't really need to worry about anything. My name is Phi. I guess you could say... I am no man."
A mysterious young girl who begins the Nonary Game as Sigma's first partner. She's quick-thinking, analytical, a smooth liar and knows things that she shouldn't be able to know.She possesses the same psychic ability as Sigma (to jump her consciousness between different timelines/parallel worlds) but unlike him she cannot control how or when it happens. She was part of a failed attempt to prevent the release of the Radical-6 virus in the Nevada Test Site; afterwards, she brought herself to Akane and volunteered to be frozen for the Nonary Game to trigger a time loop and send her consciousness back even further in time. Her backstory, true identity and overall purpose in the grand chain of events is left intentionally vague, but she compares herself to a fractional deviation that is normally rounded away and forgotten, but would actually become significant over time.
A-Cup Angst: When Sigma makes an offhanded joke about her chest, she protests that her size is C-Cup. Sigma doesn't buy that.
Big Eater: During the downtime before the next round that lasts at least 2 hours, she just went to the pantry and ate five meals.
Flip Flop of God: Word Of God previously stated that he specifically asked Kinu Nishimura, the character designer, to make Phi look like a female Santa. Later, in a Q&A, he instead claimed that it was the character's designer preference to make her look similar to Santa...
Hard-Drinking Party Girl: Hinted at. Her mind's not exactly on solving the puzzles in the lounge full of exotic liquor. Not to mention her disdain for spilling out said cocktails.
In a Single Bound: She frequently demonstrates superhuman jumping capabilities. At the end of her route, it is revealed that the source of her "powers" is the low gravitational pull of the Moon, where the game is actually set.
Inexplicably Awesome: How does she know so much about quantum theory and game theory? Why is she so cool? She's certainly not going to tell you. Not even during the Omega Ending.
Jerk with a Heart of Gold: In the beginning of the game she's cold and logical, telling Sigma to betray at every opportunity. However no matter what path, she's very compassionate, showing great a concern for all of the characters (even Dio in some situations). In one path she even has the resolve to let herself die rather than enter the White Chromatic Doors without Tenmyouji, Clover, and Quark.
Malaproper: Every so often she butchers a common saying in an incredibly bizarre way.
Manipulative Bitch: Of the Spock-esque "You lied; I implied" variant, where she will use Exact Words and implications to manipulate people into doing what she wants while divorcing herself from culpability. An example is when she states to Sigma that the chance of an opponent choosing "Betray" is very high, but never actually recommends he choose "Betray" as a counter-move.
No Man of Woman Born: Makes this joke in her introduction: she leaps through the air, but says she's not Superman, Spider-man, or Batman. "I guess you could say... I am no man."
The Not-Love Interest: She's the first girl Sigma meets, they initially have a belligerent relationship, her ending is the True Ending of the game, and she has a lot of plot relevance... but she and Sigma are never even hinted to move in a romantic direction. At best, they go from Teeth-Clenched Teamwork to something resembling friends. Although there are some scenes with them when you fail to defuse the bombs, they're not exceedingly romantic.
Word Of God confirms that Sigma and Phi will not be a couple at any point.
Unstuck In Time: Unlike Sigma, she has very little control over her jumps and is generally worse than him at remembering things across them. Since she's much smarter than Sigma, though, when she does remember her time-jumps, she's much more on the ball than him.
"You betrayed your friends. Am I right? I'm right. But you didn't have a choice, did you? You had to survive!"
A man dressed as a circus ringleader. Though he styles himself as a smooth-talking charmer, he is quick to throw out accusations, take self-serving actions and sow discord amongst the group.His true identity is "Left", the leader of the terrorist organization "Myrmidons" and high-ranking cultist of "Free The Soul". Under orders from the cult's leader, he infiltrated the Nonary Game with the intention of stopping the AB Project. To do this, he must kill Akane Kurashiki and win the Nonary Game, or destroy the entire facility. He is actually a fourth-generation clone of the original "Left", and believes that by completing this "divine mission" he will attain sainthood.
Big Bad Wannabe: He's the closest thing the game has to a Big Bad, but comes off as hapless considering the number of times he is tricked and subdued during many of the routes. Not to mention that he breaks under interrogation ridiculously quickly, and is so full of himself that he gives out the bomb deactivation codes when asked.
Circus Brat: You learn early on in some paths that Dio is a circus ringleader, fifth generation. This is, of course, just his cover story.
Commander Contrarian: The first to complain about anything, and foul-mouthed to boot. It's not long before he gets on the nerves of absolutely everyone.
Cyanide Pill: He swallows one in Alice's ending and attempts to do so in the Sigma and Phi endings.
Dead Man Switch: Has one that sets off his bombs if he drops it or it gets more than one meter from him.
Enemy Mine: In Phi's ending, Sigma theorizes that one of the reasons why everyone was finally able to trust one another enough to cooperate and reach enough BP to escape, together, was the bond they had developed while uniting to stop Dio's bombs.
Expy: His general attitude and actions during the game closely resemble Yoshimitsu Tezuka from Killer Queen.
Face of an Angel, Mind of a Demon: The only thing he's got going for him is just how neat he looks. Put him on "mute," don't listen to his words, and he looks like one cool dude. Listen to a word he says and the foulness seeps through.
Jerkass: He always, always picks "Betray" unless forced to or tricked into it by his partner. He'll have excuses a-plenty each time, but basically, the guy's just a jerk.
There is one character that he votes Ally with: he allies with Luna if he's pitted against her in the first AB game, and apparently does so of his own will. When you consider the reason why he fell in disgrace with the Cult, that was probably even a genuine decision.
Just Between You and Me: He loves to gloat when he gets one over on another player. This leads to his downfall when he freely gives out the bomb deactivation codes in the different timelines as a way of taunting the other players. Had it not been for his ego then there would have been absolutely no way to stop the bombs.
To be fair, he only reveals the deactivation codes in timelines when there is absolutely no chance for the bombs to be stopped. He gives out only one code each when confronted in his, Alice's, & Sigma's endings. In the route to Phi's (the True) route, he doesn't give any out, due to the fact that the input device had been found.
Karmic Death: In K's Route. After being revealed as the murderer of the Mysterious Woman, he is confined into a treatment pod for security reasons. Later on, he's found dead as the oxygen supply is cut off.
Nice Hat: He wears a top hat and claims to be a circus ringmaster. Word Of God says that the detonator for the bombs is in it.
Not Me This Time: You learn on K's route and on Dio's own route that Dio killed the old woman. On K's route, K also accuses Dio of killing both Luna and Alice. Dio swears that he killed the old woman and that's it, he doesn't know anything about Luna or Alice! As it turns out, when you play Luna's route, you learn that Dio was actually telling the truth: Clover killed Luna, not him, and on most of the other routes you learn Alice killed herself, so Dio was telling the truth there too.
Pet the Dog: There is one character who he votes Ally against: Luna. You can also find out that the reason he fell from grace within the Myrmidons was because he fell in love with a woman.
Which makes it a mystery on why he betrays Alice and doesn't get along with Clover. It makes you wonder what's going on under that top hat...
Red Herring Mole: He's always the first to point fingers when things go wrong, and reliably chooses the "Betray" option whenever he's given the chance. The subversion comes when he really does turn out to be The Mole. He's so suspicious that the genre savvy player probably dismissed him as a Red Herring!
Smug Snake: He just loves to push buttons and stir up paranoia within the group as part of his tactic to win (as no-one else can gain points if they all choose "Betray"). The problem is that he's so blatantly untrustworthy that no-one in their right mind chooses to Ally with him, and his poker face falls apart very quickly when he is pushed into a corner.
""Look"? That's an odd choice of words. I'm wearing a mask. How would you know how I "look"?"
A large man wearing a robotic bodysuit that completely conceals his identity. He is suffering from amnesia and only remembers his name as "K". He is incredibly polite, but chooses his options during the Ambidex Game with the cold precision of a machine.His true identity is Kyle Klim, the younger clone of Dr. Sigma Klim. Having been "born" and raised on the Moon, his armour is designed to subject his body to the equivalent of Earth-like gravity and ensure that he would not grow up frail. His purpose is to act as Zero's back-up, with his consciousness being sent back to 2028 if his father failed. His amnesia was intentionally induced with a high dose of Soparil to revert him to a blank slate for the Nonary Game.In several of the timelines, including the canonical one, the armor is instead inhabited by Akane Kurashiki for the duration of the game, with Kyle in cold sleep in the 00 treatment pod in the B. Garden (with Akane using the phenomenon "Schrodinger's Cat" to change the past from in the future, and pretending to be Kyle to preserve the events of the original timelines). For more on Akane herself, see the entry on the Mysterious Woman below.
Gentle Giant: Subverted. He is rather amiable and rarely loses his composure, but just like the others he can be devious and dishonest at times. He's also willing to use violence to get his way, especially when making a vote.
Hands-Off Parenting: A victim of this. His "father", Sigma, never really spent time with him as a child. Once K started showing interest in Sigma's work, their bond got better.
Man Child: He doesn't seem to find anything wrong with a grown man on a Zero III kiddie ride in the REC room, to Sigma's and Alice's horror. Justified, since he was a lab experiment all of childhood and apparently never learnt much of the outside world.
Meaningful Name: K can be taken one of two ways - from the first and last name of Kyle Klim, and also from Kanny, Akane's nickname in 999.
Powered Armor: Because of this, the mechanism that locks or unlocks his armour fails to function if the armour is broken or powered-down. It's also an inversion of the usual purpose of Powered Armour, which is to increase the natural strength of the wielder. Instead, K's armour acts as a massive training weight that will subject his body to forces equivalent to Earth-like gravitational conditions, ensuring that he does not grow up with a frail body.
Revenge Before Reason: In K's Route, he murders Dio by cutting off the oxygen supply in his treatment pod over the death of the Mysterious Woman...who was a surrogate mother to K in his childhood. This results Dio's bracelet being broken during his death throes, and thus leaving both K and Phi unable to proceed with the Nonary Game without being penalised. Word Of God also states that Dio's bracelet was actually broken by K, and that he did so on a gamble to test his father's love: If Sigma got the antidote, would he save either him or Phi?
The Spock: His polite, formal and dispassionate way of speaking makes him easily mistaken for an actual robot.
"Being surrounded by nature just makes me feel... happy."
A young pacifist who just wants everyone to get along so that they can all escape together. Her medical license and expertise prove invaluable during the Nonary Game, but she is vague on what her exact discipline is.Luna is actually a GAULEM: a semi-autonomous gynoid used to support the functions of Rhizome 9. She was specifically tasked by Akane Kurashiki to observe and support the Nonary Game. Her pacifistic nature is due to her being encoded with the Three Laws of Robotics, which prevents her from causing harm to any of the human players. (Though unbeknowst to her, she has also been encoded with the Zeroth Law so that the necessary deaths in the AB Project would not cause her to shut down.)
Beware the Nice Ones: She can be very vengeful if Sigma chooses betray against her. The latter of the two game overs on her path involves her getting Quark to safety while leaving everyone else trapped in the warehouse forever (in the former game over, Tenmyouji's the one who gets Quark out instead, with Luna's whereabouts unknown).
Expy: She looks and behaves very similar to June from the game's predecessor except unlike June, Luna is not secretly the quasi-evil mastermind who set up the current Nonary Game.
Which isn't surprising, considering one of her programmers is Akane herself.
Aside from Akane, she's also this series equivalent to one Sora. Both having similar dilemmas.
Facial Horror: Though more tragic than horrific, the artifical skin of Luna's face degenerates as she dies in Sigma's arms in her character ending.
Just a Machine: When presented to a young Kyle after he asked Dr. Klim for a mother, the child refused to acknowledge her as he saw her as just a robot who couldn't really feel. He interpreted her genuine feelings of sadness as "just clever programming".
Mind Screwdriver: Luna's route clears up a lot of confusion on the other routes. For example, in the timelines in which Quark doesn't actively try to kill himself, Quark mysteriously "disappears" and sometimes is never seen again. It turns out this is because Luna's the one who carried an unconscious Quark to the "treatment center" and put Quark in one of the pods after Zero Jr. unlocked the treatment center. For another example, in many of the timelines, Alice kills herself due to Radical-6, but on some of those timelines you also find Luna's body next to Alice's. The obvious suspect is Dio, but you learn on K's route that Dio didn't kill either Luna or Alice. Alice killed herself, so who killed Luna? On Luna's route, you learn it was Clover, although it turns out it was an accident since Clover had only intended to "threaten" Luna into confessing to Alice's murder.
Nice Girl: Her benevolent demeanor unfortunately serves as a Red Herring, leading many players to believe that she is putting on an act and will "betray" anyone at the right moment. In fact, throughout the game, she betrays her AB game opponents all of 0 times.
Red Herring: In Luna's route, the poor girl gets hit with this three times! First, because of circumstantial evidence discovered by one of the AB booths, which has been moved by a crane, Luna is suspected of having killed the old woman (actually it was Dio). Second, Clover mistakenly thinks Luna murdered Alice to keep her quiet (actually Alice killed herself after being infected with Radical-6), so Clover accidentally injects Luna with tubocurarine during a struggle, which incidentally is why you find Luna's body next to Alice's in a bunch of timelines. Third, eventually Clover and Tenmyouji turn up dead, handcuffed to a sink so they can't enter the doors and would get penalized, and Dio and K also turn up dead, killed by medieval weapons. Since only Sigma, Phi, and Luna (a GAULEM can't be killed by tubocurarine) are alive now, and since "dio" gets mistaken for "016" (Luna's ID number), Luna is suspected of having killed everyone (it turns out Dio killed them all, but finally K managed to kill Dio in self-defense before K died).
Team Mom: Considering she also has a medical license... She was also the GAULEM that Sigma created when K asked for a mother, though Word Of God says that K only interpreted it that way and that Luna was not created just to give K a mother.
The Four Loves: It's not a secret she's in love with Sigma. Both his innocent 22-year-old conciousness, and his true older self.
She was in part created to act as a mother for Kyle, but was rejected for being a GAULEM. She was the only one who stuck around the Infirmary to care for Kyle after he was unfrozen from the Treatment Pod, which might indicate that she still has motherly feeling towards him.
"That was when I decided I’d stay with him forever. Even if he said I couldn’t."
A precocious young boy with a sharp mind. He seems to have a strong attachment to Tenmyouji.Quark is actually Tenmyouji's adoptive grandson, whom he found as a baby. He willingly came to Rhizome 9 with his grandfather, and thus has been threatened by Zero with Tenmyouji's death if he should reveal any of the actual nature of Rhizome 9 and the current state of the world to the other players before the end of the Nonary Game.
Driven to Suicide: Like most people who contract Radical-6. He is fortunately stopped from killing himself no matter the scenario.
Happily Adopted: Tenmyouji found him as a baby and raised him to be his own grandson. The two of them love each other deeply.
Harmful to Minors: Several people think better of doing bad things because they don't want to mentally scar Quark. Unfortunately, in several scenarios, Quark is exposed to trauma, regardless.
Ill Boy: He suffers from Radical-6 and is at risk of commiting suicide unless he is treated.
My God, What Have I Done?: In his backstory, as you learn from a letter Quark gives to you in Tenmyouji's ending. A while after Quark was adopted by Tenmyouji, after their grandfather-grandson relationship was previously nothing but loving, Quark had a really bad day and, as a result, gave Tenmyouji useless garbage instead of useful salvage. When Tenmyouji scolded him for it, Quark ended up yelling at Tenmyouji and it turned into a huge fight, culminating in Quark running away from home. Quark ended up hiding out in an abandoned building during a rainstorm, and Tenmyouji still searched high and low for him even in the pouring rain. After Tenmyouji finally found Quark, Tenmyouji got horribly sick and had to be rushed to the hospital. Quark felt terrible, realizing that he had completely misread Tenmyouji's intentions. When Tenmyouji did finally pull through, Quark apologized and asked Tenmyouji if this made Tenmyouji regret ever adopting Quark. Tenmyouji's response was a surprised, "Of course not!"
You Have to Believe Me: When Dio and Quark's vote turns out to be "Betray" early in the game, if their opponent is Tenmyouji, Dio attempts to persuade Tenmyouji that Quark pushed the button, while Quark responds by screaming that Dio pushed the button and begging for Tenmyouji to believe him. (This trope turns out better than usual, though: Tenmyouji scolds Quark for losing his temper, but ultimately does believe Quark because he's known Quark for a while and could be deaf and blind and would still know if Quark was lying to him.)
"Then whatever god wrote those rules can fu—... Look, I'm not gonna accept that, all right?"
A sharp-tempered old man who describes his profession as "garbage collector", yet possesses insight into a number of scientific principles and theories. He is slow to trust others, but has a special fondness for Quark.His true identity is Junpei, the protagonist of Nine Hours, Nine Persons, Nine Doors who escaped the second Nonary Game and dedicated his life to finding Akane Kurashiki, his first true love. After the nuclear winter caused by Radical-6, he became a scavenger and handyman, eventually adopting a young infant called Quark as his own grandson. He willingly came to Rhizome 9 after Zero promised to let him meet Akane, and has been threatened into silence about the current state of the world.
Determinator: All that Tenmyouji cares about is saving Quark, everything else takes a back seat. Goes so far as to betray you and strand everyone in his ending.
Junpei hasn't changed at all - whether it's Akane or Quark, the people he cares about take priority over all else. This is also how he feels about the state of post-apocalyptic humanity. He is against Akane and Dr. Klim's actions in reversing the past, beacuse he as well as many others still living on earth have made lives for themselves in the midst of the apocalypse. He does not want to lose his current life, because even though survival has been difficult, he has accomplished something worthwhile: finding and raising Quark.
"Isn't that worth something? Isn't that the best thing humans can aspire to? Is there really any point to a world where everything is happy? Are people who struggle for a better life just idiots? Being human is about fighting even when it seems hopeless, and finding happiness even in a world that hates it."
Dirty Old Man: He seems excited when he sees a poster of a woman in a bikini. Doesn't seem to bother Quark though, especially since he knows that Tenmyouji has a cabinet full of 'Grandpa' videos!
Exact Words: In his ending, he promises Sigma he won't open the number 9 door even if he gets to 9 BP. He keeps that promise... but only because he expected Clover to open it, proceeding to escape with Quark alongside her.
Hidden Depths: This is Junpei, the person we hardly know about previously yet here it's implied that he has a basic understanding of quantum physics and was involved with the Mars simulation site somehow.
Hypocrite: He calls out on Sigma for betraying Luna in her bad ending... when Tenmyouji had done just the same to Clover, before making his escape with Quark who has 9 points.
Loving a Shadow: Essentially why he chased Akane for so long. Despite the fact that this pursuit destroyed his life, he still jumped at the chance to meet her one last time. In the "End & Beginning" epilogue, he finally acknowledges (to his deep sadness) that the innocent Akane he once knew no longer exists.
Previous Player-Character Cameo: He's actually the protagonist of the previous game. Since you're initially led to believe the game takes place only a year after the first, the revelation is surprising.
Ship Sinking: Akane's actions have caused Junpei's feelings for her after all of these time to sour like milk, instead of age like wine.
"The Akane Kurashiki I knew isn't here. She isn't anywhere..."
A scantily-clad girl who first appeared in Nine Hours, Nine Persons, Nine Doors. Though cheerful and light-hearted, she isn't the sharpest tool in the shed and is prone to rapid swings of emotion. She is close friends with Alice.She works with Alice for the Department of Defense, undergoing training to strengthen her psychic abilities. On the eve that they were set to attack a terrorist cell belonging to the Myrmidons, both she and Alice were kidnapped by Zero and placed into cryogenic stasis so they could be revived in the future for the Nonary Game. As Espers gain more power in proximity to each other, Clover was taken so that her presence would strength the psychic abilities of Sigma and Phi.
Accidental Murder: In several timelines, you find Luna's body next to Alice's. Clover believed that Luna murdered Alice and intended to threaten her into confessing, and accidentally injected Luna with tubocurarine during a struggle. In actuality, Alice killed herself due to Radical-6 infection.
Ax-Crazy: Subverted. Unlike the game's predecessor, Clover doesn't go on a murderous rampage, though she does threaten to do so.
Exact Words: Combined with a bit of The Schlub Pub Seduction Deduction. She pulls it off on Sigma in one route. She promises to "listen to whatever he says" if he chooses Betray. If he does, she gets 9 (he doesn't) and leaves, all while listening to whatever he says, but not doing any of it.
Jerk Ass: She has her moments, such as leaving everyone behind to escape in both Tenmyouji's bad endings. Although to be fair, one of those times (specifically, Tenmyouji Game Over #1) isn't Clover's fault: in a flashback we learn that Alice gave Clover a direct order as her commanding officer to escape so she can call for help for the rest of them.
She also initially considers and persuades Sigma to betray a comatose Quark during Clover's path. Granted she changes her mind at the last minute when it's time to vote, but before then she didn't seem to find anything wrong with taking advantage of a comatose kid, even if she had believed that there wouldn't be another AB game since other players may have 9 BP and would try to leave the warehouse, and Sigma and Clover would need to get 9 BP first before that happens.
Perpetual Smiler: She has a habit of grinning at innapropriate times, though there are times when she stops smiling, especially when she and the others stumble across Alice's dead body in certain timelines.
Red Herring: Especially for those players who played the first game and remember what happened in the Axe Ending. Though the game teases the possibility of Clover snapping again following Alice's death, the only death she was involved in was an accident - and due to circumstances it wasn't actually a real murder.
"The existence of this mysterious "Alice" and of this ice that doesn't melt is just ridiculous!"
An enigmatic, exotic woman who seems to be a close acquaintance of Clover. A popular rumour is that the water that composes her body is Ice-9, an isotope of water whose freezing point is just around 36°C (96°F).She works for the Department of Defense as an anti-terrorism agent investigating the Myrmidons and Free The Soul, and seeking to avenge her father's death at their hands. She was kidnapped alongside Clover by Zero on the eve of a raid on the Myrmidons HQ, then placed into cryogenic statis so they could be awoken decades later for the Nonary Game. Alice was specifically chosen because of her savant-level grasp of mathematics, which proved vital for decrypting a Myrmidons code. As for the rumour about her body being made of Ice-9, that's not true... probably.
Butt Monkey: In in the first AB Game, except for her route path, she is always betrayed, thus causing her BP to fall to 1 quite often. Not only that, she always succumbs to Radical-6 and is found dead in the Crew Quarters in most timelines before the second AB Game starts.
Her bad luck in the game is exemplified in Clover's path where she is forced to compete against Dio three times in a row, ensuing that her BP will remain 1.
Cool Big Sis: Thought they are not related, Clover sees Alice as this.
Driven to Suicide:She begins showing signs of Radical-6 infection about halfway through. Whether or not she goes through with the suicide depends on the timeline.
Everyone Looks Sexier If French: French mother, Egyptian father. She seems completely unfazed by the idea of people mistaking her for a legendarily beautiful Egpytian queen.
Hidden Depths: Even after the revelation that she's a secret agent, it comes as quite a surprise when it's revealed she's a math genius, able to quickly determine the factors of a 25-digit integer.
Jerkass: In her route, she betrays you twice in a row. The first time could be excused as her not trusting you, but the second time counts as a Kick the Dog moment as she picks betray again, knowing that you only have 1 BP left. In fact, in the Alice game-over ending where you pick "Ally" and thus get reduced to -1 BP, this essentially means Alice kills you!
Even worse, she is betrayed by everyone else in every other timeline. When Sigma chooses to Ally with her, she betrays, mocks Sigma for picking the very same option that she chooses in all other timelines, and calls him an idiot. The second betrayal also comes after Sigma saves her life with a cure for her disease and is a complete surprise, as she was thought to be asleep in the infirmary at the time and thus would've defaulted to Ally.
Heel Realization: When cornered in the B. Garden, she admits that she betrayed Sigma because she was terrified during the events of finding the bombs and having succumbed to Radical-6. Waking up after being cured only made her panic ever more because of the second AB gaming nearly ending, and the panic had clouded her judgement as she picks betray. Breaking down in tears, she admits she's a terrible person and feels that it'd be justified if Sigma had killed her out of vengeance there and now. He doesn't.
Mind Screwdriver: For the Gainax Ending of the previous game. Turns out she's a normal person with a past and a childhood, not an ancient Egyptian queen with a body made of Ice-9. As she explains, there was an ancient Egyptian mummy recovered that remained frozen at room temperature, but the "All Ice" mummy got corrupted into "Alice" when it became an urban legend, which is how the Alice we know got mistaken for "All Ice". It didn't help, Alice admits, that sometimes just for kicks, she'd tell people that maybe she was the mummy but lost her memory or something.
Sacrificial Lion: She's a mystery woman with secret knowledge, fighting abilities and one killer outfit. If the world were fair, she'd be a powerful ally for good. The world is not fair, because she almost always succumbs to Radical-6 and commits suicide.
The Tease: The one who flirts the most with the other guys, although she never uses it to her advantage when decisions need to be made.
They Killed Kenny Again: Happens so much in several timelines that the player is left wondering if she can even be saved.
"I'm just the... facilitator for this facility. I just do what I'm told to do!"
The AI controlling the Nonary Game, who manifests as an image of a rabbit. He is not the mastermind of the Nonary Game, but merely a construct programmed by the real Zero to facilitate it. He likes to makes rabbit puns. His true designation is Lagomorph, and can break certain rules in the game in accordance to his orders.
Just a Machine: His engrossing personality to the players may make some doubt that he really is an A.I. Seeing him completely subdued & submissive to Akane is pretty jarring.
Moon Rabbit: How appropriate that the AI controlling the facility on a moon base would be a rabbit.
The Nicknamer: All the participants get nicknames from him. Sigma is "Siggy", Phi is "Phido", Clover is "Cleaver", Alice is "Alas", Quark is "Quirk", Tenmyouji is "Tenmyoldi", Luna is "Moony", Dio is "B.O.", and K is "Potassium".
Pungeon Master: The rabbit and vegetable puns fly freely with this one.
Troll: After the first AB round, he tearfully proclaims how sad he is that he won't see the players again... and then bursts out laughing at the idea of him being sad, complete with "neener neener"s. Sigma calls him a dick. He responds, "you mad?"
You Bastard: There's only one time he has any real dialogue after the first AB Vote: to tell you how much you suck for betraying Luna at the last leg of her path. So far you'd allied with her twice and breaking her trust right when she was the last living suspect for the murders is too much for her.
The mastermind behind the Nonary Gamenote Zero II, in the context of the entire series, otherwise known as just "Zero". He/she is nicknamed "Zero Sr." by the players to distinguish him/her from the A.I. calling itself Zero III. According to Zero III, the true identity of Zero Sr. is one of the nine players of the Nonary Game.Zero Sr's true identity is Dr. Sigma Klim, an older version of Sigma who collaborated with Akane Kurashiki to fulfil the future she had seen in her psychic visions and rewrite history to prevent the outbreak of Radical-6. Due to the success of the AB Project, he manages to send his consciousness back in time, swapping it with that of his 22-year-old self.
Badass Grandpa: Kept his body in good enough shape for Sigma to easily take down Dio and not notice any differences from his 22 year old body
Failure Hero: Despite succeeding in sending his mind to his 22 year old self on Christmas 2028, he was not able to prevent the outbreak of Radical-6 in the Mars Mission Test Site; consequently losing his arms & right eye in the process before returning to his true body several weeks after the outbreak occured. It's all but said that the "unexpected variable" in the Golden Ending will help him & Phi accomplish that which they couldn't do alone in the next Zero Escape game.
Hannibal Lecture: The only time we get to hear him speak is when he delivers an odd speech comparing humans to termites, in that termites build massive structures their individual brains are too tiny to comprehend. This is him hinting that only someone with the power to mentally jump through time can properly appreciate the true nature of things.
An elderly woman whose body is discovered early in the Nonary Game.Her true identity is Akane Kurashikinote Zero I, in context of the entire series from Nine Hours, Nine Persons, Nine Doors, one of the conspirators behind the AB Project and the current Nonary Game. Using her powerful psychic foresight, she orchestrated a decades-long plan to rewrite history in order to prevent the release of the Radical-6 virus and get her revenge on the last remaining mastermind behind the first Nonary Game: Brother, the leader of Free The Soul
Blue and Orange Morality: Word Of God states that because of Akane's ability to see and live other futures and pasts, that she has experienced so much that it is as if she has lived for a million years, and accordingly her concept of morality has become different from an ordinary person's.
I Did What I Had to Do:In order to create history as she'd seen it and to nurture the powers of Sigma and Phi, death was unavoidable. Hers and several others, depending on the timeline.
It's Personal: Yes, there's the whole "save the world" bit, but there's also that little matter of Brother being the person ultimately behind the First Nonary Game. To be fair, being burned to death does tend to stick with a person.
Time Abyss: From a mental standpoint, in any case. She is about as old as Tenmyouji, physically. According to Word Of God, her psychic powers have developed enough that she can send her consciousness across time and space, almost at will. She has seen and felt enough in this way that she could be said to be millions of years old, mentally.
Vocal Dissonance: In the English voice acting, Young Akane sounds more cold, calculating, and mature than her young and innocent looks would lead you to believe.
Now Which One Was That Voice: Strangely, his English voice actor is a complete and total mystery, partly due to the English V As much uncredited, and partly because the role is so minor. Even when asked, people behind the dubbing said that they could not say who their voice was.
The mysterious leader of the cult "Free The Soul". He is an esper, born with psychic abilities that were said to expose him to "the worst aspects of humanity". After the murder of his beloved brother Left (and subsequent police cover-up on behalf of the killer), he was driven to madness and came to believe that God had given him a divine mission to cleanse the world and bring forth a new species of humanity. To this end, he founded the cult "Free The Soul Of Y" (later truncated to "Free The Soul") and the terrorist organisation "Myrmidons". Somehow he was able to orchestrate the release of the Radical-6 virus into the general population, which led to a disaster that nearly drove the human race to extinction. Through his psychic abilities he learned of Akane and her attempt to stop him by rewriting history, so he sent Dio to Rhizome-9 to stop it.
Mission from God: After Left's murderer got away with his crime scotfree, Brother went into a deep sabbatical for nine days and nights. On the tenth day, he believed he had contacted God to give him his mission to create a new form of humanity & wipe out those who were "unclean".
Staying Alive: Word Of God states that he is still alive even in the Bad Future of this game despite being an old man in the "present". How has yet to be revealed conclusively, but one rumor is that he has cast his body into another time.
An unknown consciousness that inhabits K's body in the secret ending of the game. Akane suggests that this person will be the key to preventing the virus outbreak. Its true identity and nature are currently unknown, but Word Of God suggests this consciousness is meant to represent the player.
Big Good: Akane believes ? to be this because of their ability to freely travel through space and time, saying "Only you can right the horrible wrongs of this world".
