Main Characters


PAFF / Aroma White / "Drew" / Kaori Minamiya
Aroma Post-Reinvention
One of the most if not the most popular idols on the music scene, PAFF (real name Aroma White) boasts a large fanbase who call themselves "Puffs". Despite her success and general love of singing, Aroma White is rather introverted off-stage. Much of her public personality is cultivated by her agents, the most prominent of whom is her sister Helena. She is plagued by the aftermath of a car accident, which left her unable to recall much of her life prior and left her with the fear of forgetting everyone all over again. The damage to her brain from the accident is kept in check by three stabilizer disks that float around her head.

However, following her performance at the mysterious Aesir-FEST, Aroma suddenly begins recalling memories that contradict what she's been told about her life...

  • Adorkable: Unlike what her status as an incredibly successful idol would suggest, Aroma off the stage is endearingly shy and awkward.
  • Adult Fear: Getting into a traumatic car accident and constantly running the risk of losing your accumulated memories is rough. Finding out that you might actually be a child who was kidnapped from your real family and turned into a replacement for someone else's family might be worse. The original Aroma White faced an adult fear of her own, heavily implied to have been sexually assaulted by someone she had come to trust, in her case her sister's husband.
  • Affectionate Nickname: Neko calls her "Aroma-chan". This is significant as the only other person Neko gave the honorific -chan is Linda, her best friend. Even after Aroma actual name, Kaori, is revealed, Neko decides to keep calling her Aroma-chan because that is the girl she's grown to know.
  • All-Loving Hero: Poor girl can't bring herself to hate anyone regardless of how they've wronged her, whether it be Neko for repeatedly badmouthing her online or Noah for outright erasing her memories to turn her into the real Aroma's replacement.
  • Amnesiac Hero: In a less conventional sense. The accident resulted in her forgetting everything from her childhood, but she retains her memories afterwards. However, everything she's known about herself is a result of memory implants from the real Aroma, and, aside from some flashes, she is completely in the dark as to who she really was.
  • Amnesia Missed a Spot: After recovering from her accident, Aroma can play the piano, an ability which her own sister notes she didn't have before. This is one of many clues that Aroma may not be who she believes herself to be. Kaori was an avid piano player from a young age.
  • And I Must Scream: While comatose from the car accident, Aroma was seemingly conscious of the world around her to an extent as she was able to communicate by moving a finger even though the rest of her refused to wake up.
  • Apologizes a Lot: "I'm sorry" is practically her catch-phrase with how often she says it.
  • Awesome Mc Coolname: Aroma White. Her original name, Kaori, is somewhat more conventional.
  • Break the Cutie: Poor Aroma goes through this on two fronts as a consequence of her memories reawakening. The original Aroma, who already was dealing with social anxiety, was sexually assaulted by Noah, a man she had come to trust, before getting into a car accident that left her in a coma. Kaori was kidnapped from her home, trafficked in a sealed container like a product, then had her memories violently sealed away and altered via Electric Torture. Aroma has to now cope with the traumatic memories of two people.
  • Broken Ace: Is an incredibly talented and successful singer who was also one of the top students at The Academy. She is also constantly plagued by the trauma of having forgotten everything prior to a car accident and incredibly submissive to the wills of others. There's also the fact that she was kidnapped from her home and stripped of her original identity to be someone else's replacement.
  • Broken Pedestal: Neko was actually a huge fan of PAFF and was overjoyed when Monophonic gave her the chance to do a collaboration, but her opinions on PAFF soured significantly when Neko received none of the credit for their collab work. Not helping was that, due to Helena constantly keeping Aroma from seeing Neko, Neko was left with the impression that Aroma was aloof and arrogant. Of course, Aroma isn't like that at all. Becomes a case of Rebuilt Pedestal once Neko finds Aroma on the streets and takes her in, and they get along incredibly well. The fact that Neko gives Aroma the affectionate nickname "Aroma-chan" speaks a lot to their new bond. When the incident that initially soured Neko's opinion of Aroma is finally brought up, Neko doesn't even hold it against Aroma, acknowledging that it was Mono's fault.
  • Buxom Is Better: According to Vicky, Aroma is a D-cup. Neko also comments on their size...and later fondles them.
  • Cannot Talk To Men: Though Aroma is just shy all around, she notes in particular that her social anxiety flares up whenever she has to talk with males. Noah is the only man she can hold a conversation with without constantly stammering. It makes it all the more heartbreaking and nightmarish when Noah is the one who sexually assaults her.
  • Changeling Fantasy: Something of an inversion as the life of stardom she knew is the false life, and her real life in Node 03 was somewhat humbler.
  • Child Prodigy: At the age of 10, she served as a replacement for a singer at a bar Helena worked at. The patrons were completely floored by her performance.
  • Clark Kenting: Her means of avoiding recognition in public after running away from home involves dyeing her hair gray, tying it up in a ponytail, and dressing in a jacket and athletic pants. Zig-Zagged in that Neko still has to distract people in smaller areas such as when they visited The Academy. Those who know who she already is such as Vicky also can recognize her. When the image of her running with Neko is leaked, she's identified almost immediately.
  • Dead All Along: The real Aroma had only a month to live after her operation failed. This necessitated the need to turn Kaori into her replacement.
  • Expository Hairstyle Change: Dyes her hair slate gray and ties it up in a ponytail after running away from home, indicating the moment she truly sets out to discover her identity and break away from her dependence on Helena. Neko was actually the one to reinvent her hairstyle so that Aroma could walk through the streets without being recognized.
  • Extreme Doormat: She's generally very submissive towards Helena, doing whatever she asks with only a moment of hesitation at most. This is what led to her failing to meet Neko despite sincerely wanting to, subsequently leading Neko to get a false impression of her. This makes it all the more significant when she screams at Helena that she no longer wants to perform.
  • Fairy Companion: Has a mechanical one in the form of Tuner-san, a small flying personal assistant.
  • Foil: Is this to Neko. Both of them are very talented musicians who love music and have large, dedicated fanbases, but they are pretty much diametric opposites when it comes to everything about their respective character. Aroma is a shy and quiet Nice Girl, while Neko is a loud-mouthed and confrontational Jerk with a Heart of Gold. Aroma's entire career was plotted for her from the start by her sister and Mono. Neko pursued her career independently on a whim, and she ultimately rejected being under Mono because they refused to give her her due. Even their character arcs are exact opposites. Aroma's arc is about breaking away from those who have been controlling her entire life and discovering her identity as an independent entity. Neko's arc, which was covered in her DLC chapter, was about accepting other people into her life and learning to live with her family.
  • Genre Motif: Pop
  • G.I.R.L.: Gender-inverted. After waking up from her collapse on stage, she secretly sets up an alternative account on iM under the masculine name "Drew" due her original account being heavily monitored by Mono. Her "Drew" account has her voicing her concerns over her growing identity issues as she begins recalling Kaori's memories.
  • Hair Color Dissonance: Aroma's hair is supposed to be a dark shade of magenta, but certain in-game art depicts it as either brown or a shade of pink. Artists have similar problems with Aroma's hair after Neko reinvents her appearance. It's stated to be slate-gray, but some illustrations have it colored almost pure white.
  • Hidden Depths: Aroma is noted to be one of the top three students in The Academy, on top of being a wildly successful pop singer.
  • Identical Stranger: Images reveal that Kaori bore more than a passing resemblance to the real Aroma with only somewhat messier hair, though she still did undergo Magic Plastic Surgery to erase any possible physical differences entirely.
  • Idol Singer: While PAFF doesn't have the bubbly personality, she has pretty much everything else, including a strictly controlled image, and a company which terminates her contract as soon as she goes missing, leading to much outrage from her fans.
  • The Immune: She was exposed to the Ender virus after the containment system she was kidnapped in accidentally was opened in one of the contaminated areas but didn't die. Like Nora, her body seemingly could coexist with the virus, the byproduct being the development of her own "Eye of Horus" abilities.
  • Irony: She's possibly the only person who actually gained memories after Aesir-FEST, an event that explicitly gave the attendees amnesia.
  • Made of Iron: A somewhat understated example but after running away, Aroma spent two weeks on the streets with barely any food and hydration due to her fears of being recognized and only began to feel the effects towards the tail end. Not bad for someone who's been sheltered most of her life.
  • Meaningful Name: Her real name Kaori means "fragrance" in Japanese. It's fitting considering she was turned into a replacement for a girl named Aroma.
  • Modesty Shorts: Her idol outfit has these.
  • Nice Girl: Is all around a kind and considerate person who loves her family, greatly appreciates her fans, and generally just wants to make people happy. Despite her Shrinking Violet nature, she genuinely wants to connect with her many fans and expressed interest in becoming friends with Neko, even though that went south due to events she was locked out of the loop for.
  • Odd Friendship: Is pretty much Neko's exact opposite personality-wise, but the two of them become fast friends once they finally meet each other in person.
  • Older Than They Look: Somewhat downplayed, but appearance-wise, she could still pass for a teenager even though she's 24.
  • O.O.C. Is Serious Business:
    • When bullies threaten her and her friend Iris at The Academy, one of Aroma's stabilizing discs becomes removed. She immediately grabs one of the bullies and coldly orders them to apologize to Iris, which is particularly unusual because of how timid Aroma usually is.
    • After recovering from suddenly collapsing on stage, Aroma becomes progressively more withdrawn and irritable. It comes to a head when she verbally lashes out against Helena when Helena tries to prod her towards doing another performance. This, coupled with some nightmares that followed, prompts Aroma to run away.
  • Psychic Nose Bleed: Both times she accesses footage from past surveillance cameras, she wakes up with her nose bleeding. It's similar to what happens with Nora...
  • Quest for Identity: What defines her character arc. Though in a variation, it's more finding out if who she believes herself to be is actually a lie.
  • Rape as Backstory: It's heavily implied the original Aroma was the victim of an attempted rape or sexual assault by her sister's husband Noah as a teenager, though he passed out before he actually got to do anything.
  • Ship Tease: With her childhood friend Hayato. Several scenes show that they are the most important person in each others' life, and their reunion is portrayed almost romantically.
  • Shrinking Violet: She's rather quiet and shy outside of her performances, though she does sincerely wish to communicate with her massive fanbase. It's shown that the real Aroma had similar problems with nerves in large public spaces but was somewhat more outgoing when talking with her Academy friend Iris. As Kaori, she was significantly more sociable in general, being the reliable big sister figure during her time in the orphanage.
  • Significant Wardrobe Shift: After Aroma runs away from home, illustrations of her show her wearing a simple jacket, top, and athletic pants, which are a far cry from the formal dresses she wore previously. It indicates her break from her manufactured identity as an idol.
  • Tall Poppy Syndrome: Suffered from bullying in The Academy due to this. Many other students grew resentful of her being one of the top students despite having supposedly forgotten most of her past due to the car accident. Rumors spread that she was in fact faking her amnesia for the sake of drumming up early publicity for her singing career.
  • Technopath: She seems to have abilities similar to Nora in that her brain seemingly can stream camera feeds, though she only seems to be able to access feeds from the past. When she finally meets Nora, Nora confirms that they possess the same power.
  • Tender Tears: As a consequence of regaining a lot of distressing, foreign memories in a short span of time, Aroma becomes prone to fits of weeping as she struggles with the trauma and confusion.
  • Wistful Amnesia: Aroma's motivation for running away from home is the growing feeling that she isn't herself, which understandably causes her a great deal of emotional turbulence.
  • You Gotta Have Blue Hair: Her hair is a dark shade of magenta. It's later revealed to be dyed, and her natural hair color is black. Neko later dyes her hair slate gray after Aroma comes to her looking for a place to stay so that Aroma can walk through the streets without being noticed.


Neko#ΦωΦ / Neko Asakura
Neko as a teenager

A Gamer Chick and livestream personality also known for the music singles she produces and her inflammatory fanbase. She harbors some resentment towards PAFF and her record label Monophonic due to a collaboration they did in the past that Neko was never credited for. She also shares a sibling bond with Xenon, though her fans insist there is something more going on with them. Because of her dislike of Mono, she was never present for Aesir-FEST.

Neko Asakura used to live in Node 03, an impoverished section of the setting, as a child but moved to Node 08 with her father. Her struggles with acclimating to the numerous changes in her life led to her discovering her love of music as well as meeting with Xenon and his friends.

She ends up a victim of a viral attack from apparently AEsir himself and is incarcerated by the ARC due to the attack originating from her phone. She is later released, though Xenon is now set on proving her innocence. Shortly afterwards, Neko finds PAFF wandering the streets...

  • Ambiguously Bi: A case where it's ambiguous in both directions. She is rather touchy-feely with both her friend Linda and Aroma and repeatedly comments on how they are cute. She also says to Aroma that she doesn't mind having a "cute girl" waiting for her every time she returns to her room. Her relationship with Xenon remains in a Like Brother and Sister arrangement, though there are also hints that she might have a small crush on him. She vehemently denies it whenever others bring it up however. She also mentions off-hand that she finds ConneR handsome.
  • Animal-Eared Headband: Wears a cool set of headphones with cat ears on them.
  • Animal Motifs: In case it wasn't clear, Neko is closely associated with cats.
  • Annoying Younger Sibling: She treats her stepbrother Kenta like this. She is also one in a surrogate way to Xenon, who often expresses exasperation towards her antics.
  • Batman in My Basement: After Aroma runs away from home, Neko allows her to stay in her room. However, she keeps this a secret from her parents, possibly so they don't tell the authorities about what happened to the missing idol.
  • Be Careful What You Wish For: Upon reading about the newly-released MeowBots, Neko immediately sought funding to buy several of them, believing they could assist her in her day-to-day, including her streaming and music production. Fast-forward to later on in the story, and Neko finds the MeowBots she's stuck with to be more annoying than helpful.
  • Cat Girl: As her name indicates, Neko has a cat-girl theme, wearing a headset with cat ears.
  • Cats Are Mean: She's fairly abrasive and bratty in ways similar to actual cats. That doesn't mean she doesn't have a good side though.
  • Cute Little Fangs: She has these, which furthers her cat motif.
  • Damsel out of Distress: When she was a teenager, she was kidnapped by loan sharks who were going after Yukiko. She inexplicably managed to escape and went to Xenon to hide out.
  • Fairy Companion: She has mechanical ones similar in purpose and design to Aroma's Tuner-san called "MeowBots". She finds them more annoying than helpful however.
  • Foil: Is this to Aroma. Both of them are very talented musicians who love music and have large, dedicated fanbases, but they are pretty much diametric opposites when it comes to everything about their respective character. Aroma is a shy and quiet Nice Girl, while Neko is a loud-mouthed and confrontational Jerk with a Heart of Gold. Aroma's entire career was plotted for her from the start by her sister and Mono. Neko pursued her career independently on a whim, and she ultimately rejected being under Mono because they refused to give her her due. Even their character arcs are exact opposites. Aroma's arc is about breaking away from those who have been controlling her entire life and discovering her identity as an independent entity. Neko's arc, which was covered in her DLC chapter, was about accepting other people into her life and learning to live with her family.
  • Gamer Chick: Though unlike most examples, she isn't a particularly skilled gamer. Many of her streams end in Rage Quits. However, it may just have to do with the games she streams as she still holds the high score for a game at the local arcade she used to frequent.
  • Genius Ditz: She's undoubtedly a talented music producer. She's not nearly as smart when it comes to everything else as Xenon can attest.
  • Genki Girl: If nothing else, she's a constant source of energy.
  • Genre Motif: Techno/Electronic Music
  • Hartman Hips: Full-body art of her shows that she has fairly wide hips.
  • Heroic BSoD: The stubborn willpower she demonstrated over the course of the entire story evaporates completely once she's informed of Cherry's passing. She just limply decides to return home, even willing to abandon Aroma, who she had previously been adamant in helping.
  • Heroic Willpower: Despite being implanted with a memory implicating Xenon in the attack on her stream, she still desperately wants to believe that Xenon is innocent. Ivy takes note of this, citing it as another reason why Humans Are Special.
  • His Name Really Is "Barkeep": You'd think that her name was just some social media handle she chose to coincide with her cat motif, but that's her actual birth name minus the emoticons. Might also fall under Who Names Their Kid "Dude"?. Doubles as Meaningful Name once you switch the game's language to Japanese and learn that while her first name is pronounced like "猫" (meaning "cat"), it's actually written "音心", an inverse of "心音" which means "heartbeat", befitting her beat-heavy musical style.
  • Idiot Hero: She isn't the kind of person to think long-term too often. Xenon calls her an idiot on several occasions.
  • Jerk with a Heart of Gold: She's ill-tempered, loud-mouthed, and somewhat bratty, but she is also genuinely affectionate to those she considers friends, helped her father get rid of her stepmother's debt collectors despite her personal issues with her, and allowed Aroma to stay in her home even though she had since formed a bitter one-sided rivalry with her.
  • Like Brother and Sister: Shares this kind of bond with Xenon, with Xenon acting as the experienced older brother who listens and helps her through her problems, and Neko being the annoying younger sister who always gets in trouble.
  • Locked Out of the Loop: Wasn't present for Aesir-FEST and thus isn't aware of the true extent of the fallout that followed. That changes after AEsir himself apparently contacts her via her phone, subjecting her entire stream to a viral attack in the process.
  • Multicolored Hair: Has a pink streak on her left fringe. When she was a teenager, all of her bangs were dyed pink.
  • Not So Different: Upon finding out about Xenon's arrest, Neko finds herself unsure of whether or not she can trust her memories due to Ivy tampering with them without Neko's knowledge, which is similar to the dilemma Aroma faces. This is something that the two of them actually discuss.
  • Odd Friendship: Her and Aroma's personalities are pretty much complete opposites, yet they quickly become friends once they meet in person, Neko completely burying her one-sided rivalry with her.
  • Older Than They Look: Would you guess she was 20 just by looking at her?
  • Out-of-Character Alert: Her parents grow suspicious of her activities after she suddenly stops badmouthing PAFF.
  • Sci-Fi Bob Haircut: She wears her hair like this in the present. As a teenager, her hair was more parted to one side.
  • Ship Sinking: Her implied crushes on both Aroma and Xenon ultimately don't go anywhere, with Xenon instead reconciling with Cherry and Aroma being teased with her childhood friend Hayato.
  • Ship Tease: She has some with both Aroma and Xenon that ultimately doesn't go anywhere. See Ambiguously Bi and Ship Sinking above.
  • Significant Wardrobe Shift: As a teenager, she wore leather jackets and tanktops with torn-up jeans, indicating her difficulties with her home life and her status as The Runaway. She switches to looser, more casual clothing after accepting Yukiko into her life and moving back home.
  • The Napoleon: She gets noticeably snippy when people bring up her short height.
  • The Runaway: While still a teenager, she left home for a very long period of time after a very heated argument with her father. She spent much of her time in Xenon's home.
  • The Scapegoat: Is incarcerated by the ARC for a period of time after her stream, which had nearly 80,000 viewers at the time, comes under attack by a "malicious connection". She was blamed as the connection apparently came from her phone. Through a call that was apparently from AEsir himself...
  • Third-Person Person: Often refers to herself as NEKO during speech. It highlights her general immaturity. It also seems to be a deliberate choice on her part as she slips into using first-person pronouns whenever she's flustered or panicking. When talking to herself in private, she also refers to herself using first-person pronouns.
  • Unknown Rival: Aroma doesn't seem to be aware that Neko even hated her. Considering how much Helena shelters Aroma, it's not exactly surprising.
  • Unwitting Pawn: The 2.0 update reveals that AEsir attacked her and manipulated her memories of the event to frame Xenon.
  • Womanchild: She's 20 but still acts very much like a teenager, being generally loud-mouthed and rebellious towards those who establish themselves as her elders. It causes Xenon some exasperation.
  • Who Wears Short Shorts?: Art usually depicts her wearing these when she's not wearing sweatpants.
  • Wise Beyond Her Years: Definitely wasn't and still isn't most of the time, but when she was eight, she did have a moment of this. After her father informed her that he and her mother were getting a divorce, with her father moving to Node 08, she was given the choice of who she would stay with. Both of them assumed that, because of Neko's closeness to her mother's side of the family, she would choose to stay in Node 03. They were both surprised when Neko chose to go with her father, Neko's reasoning being that while her mother would always have her extended family her father would be all alone.

    ROBO Head 

ROBO_Head Unit 02
A friendly robot that is also able to compose music. He enjoys posting links to various articles and can analyze statistics with ease. He was one of the musicians that performed at the mysterious Aesir-FEST, though unlike the others, his memories were merely corrupted and were thus repairable. He attempts to make sense of what happened during the event and how it may fit into a much larger picture.

This search then leads him to news of an explosion in Node 03. For whatever reason, forces seem to be at play to keep him from finding out more about the event. He knows there's a particular person in Node 03 he wishes to see once again, yet his own programming seems to be hindering him.

He was created by Nora first to communicate with her caretakers and test her emotions. He was then upgraded into protector with the ability to distinguish between right and wrong. Upon escaping Nora's tormentors, Nora leaves him on a train so that he can live as an independent entity.

  • Accidental Misnaming: Neko repeatedly mispronounces his name as "Ropohead".
  • Benevolent A.I.: ROBO_Head loves composing music and sharing data analyses with his fans. But most of all, he loves Nora, and wants her to be happy.
  • Beware the Nice Ones: He's a friendly robot overall who enjoys making others happy with his music and links. However, he also horribly wounds Kim and outright kills Lam when they threaten Nora's life. It's later revealed that his arms actually have guns installed into them.
  • The Comically Serious: Keeps his dry, statistics-minded approach to everything even when responding to the most inane of iM comments.
  • Determinator: Doubly impressive considering he's a machine. He will overcome every pre-programmed and physical roadblock in his way just to find out what happened to Nora. Even when Nora herself resorts to some rather violent means to convince him to leave Node 03, he always returns and waits for her.
  • Genre Motif: Hardcore Techno/Dubstep
  • Grew Beyond Their Programming: Over the course of Nora's chapter, he displays more and more humanlike behavior, such as asking philosophical questions and lying. In his own chapter, he eventually alters his own setting to remove the command Nora gave him which prevented him from returning to Node 03.
  • He Knows Too Much: After discovering the true nature of the aftermath of Aesir-FEST, he's sent an anonymous message warning him to cease posting information related to the incident and implicitly threatening him and Nora.
  • Mr. Exposition: A variant as he provides the most direct information of significant events in the iM System, which otherwise relies purely on rumors and somewhat vague second-hand accounts, via his links to news articles.
  • Perpetual Smiler: The times his face is displayed, he always a simple smiley face. It turns out he does have an "angry face" that appears whenever he sees a perceived threat.
  • Restraining Bolt: Nora installed him with one to ensure he wouldn't attempt to research and follow his creator. He changes his system settings to defy it after being notified of an explosion in Node 03.
  • Spanner in the Works: Ivy inflicted everyone attending Aesir-FEST with amnesia to initiate her extraction of their emotional data. It's likely that she didn't take into account ROBO_Head's nature as a machine. After restoring his corrupted files, ROBO_Head proceeded to reveal the mass mind-wipe to the public.
  • Spock Speak: Being a walking computer, he naturally speaks like this.
  • That Makes Me Feel Angry: He doesn't normally express emotions, but when he's looking through files about his past, his response fits this trope:
    Emotion database comparison...... Complete
    Decision: This unit currently in "Sad" emotion
  • TV Head Robot: It's in the name. His head is a computer monitor.
  • Unwitting Instigator of Doom: His return to Node 03 and refusal to leave puts Nora and her team in danger, as the Mogura use it as an excuse to launch an attack.
  • What Measure Is a Non-Human?: Played With interestingly in that he's treated as an autonomous entity despite being identified as a robot. The more mechanical aspects of his mindset are treated more as an amusing quirk than something to justify any kind of prejudice.


Xenon / Simon Jackson / X
A talented young systems administrator at ARC who is almost never seen without his signature helmet on. Also the head of his own rock band, which is composed entirely of virtual clones of himself.

Though he is a relatively new member of the ARC, Xenon is personally responsible for the creation of many of the cyTus system's firewalls and security protocols, which have done much to deter hacker attacks and virtual crimes. Despite these successes, he has yet to be promoted. He's possibly involved with a much less legal project that threatens the very security he helped established.

He ends up in ARC custody for his suspected link to the AEsir attacks, though it turns out that he's completely innocent. Cherry and Joe later break him out with the aid of ConneR. He's currently on the run with Cherry.

  • Aloof Ally: Is technically a member of ConneR's secret research team but very rarely actually works with him unless he needs ConneR's personal expertise, largely because ConneR's personality rubs off him the wrong way.
  • Amicable Exes: He used to date Cherry, but the two remain on friendly terms. However, he is somewhat wary as to why Cherry suddenly decided to show back up in his life.
  • Berserk Button: His demeanor darkens significantly whenever his sister Shannon is brought up, though that wasn't always the case. It might have to do with some unknown incident he and Cherry were involved in that resulted in Shannon losing her memories and several people dying.
  • Big Brother Instinct: Towards Neko, stemming from an incident where he saves her from getting into a fight at the arcade. Also towards his actual younger sister, Shannon. It is revealed that Simon was actually researching ways to cure Shannon's fractured mental state. Recalling this is what leads Simon to believe he's actually AEsir.
  • Bishōnen: The times we see him without his helmet reveal a fairly handsome man with somewhat long, wavy hair.
  • Blinding Bangs: In keeping with his status as The Faceless, the times we do see his face underneath his helmet, his eyes are completely obscured by his hair.
  • Cool Helmet: Xenon is usually seen wearing a helmet that fully covers his head, with a single red light glowing in the center of the eye slot.
  • Former Teen Rebel: Works diligently for the very organization he once rebelled against as the vigilante hacker X. It's later implied that he's not exactly loyal to the ARC though.
  • Frame-Up: Ivy frames Xenon for her activity as AEsir and alters his memories so that he believes he's involved.
  • Genre Motif: Rock/Metalcore
  • Good Is Not Nice: He's a kind man at heart who seeks to help those in need without the desire for anything in return. He can also be blunt, cold, and aloof even to those he considers friends.
  • Hero with Bad Publicity: It can't get much worse than people thinking you're a cyberterrorist.
  • Hidden Depths: Despite his heavy immersion in digital technology, right down to creating virtual clones of himself to populate his rock band, he still uses physical instruments for his songs. He tells ConneR that without physical strings, the guitar wouldn't sound as good.
  • Hollywood Tone-Deaf: It's more of an Informed Attribute due to the general lack of voice acting in the logs, but Xenon apparently has a comically bad singing voice that Cherry and Joe ribbed him about during their Crystal PuNK days.
  • Icy Blue Eyes: When his face is fully shown, it's revealed that he has cold blue eyes. It fits his somewhat aloof character.
  • It's All My Fault: While he was angry at Cherry's father for killing his father in an incident that also led to his sister's fractured mental state, in the present, he admits to Cherry that he was angrier with himself for failing to notice the problems occurring in Cherry's personal life that led to the situation spiraling out of control to begin with.
  • Like Brother and Sister: Describes Neko as being like a sister to him and generally is put-off by suggestions of the two of them being a couple due to the age difference between the two of them.
  • Like Father, Like Son: According to his mother, he's very much like his father personality-wise. Besides their serious demeanor, they also have the same strong sense of justice.
  • Love Hurts: He really doesn't take Cherry's death well. Shortly after Cherry's death, everyone else enters her hospital room to find it completely torn apart and a sizable hole in the wall with Xenon nowhere to be found...
  • Me's a Crowd: As stated before, his rock band consists of virtual clones of himself.
  • Mistaken for Cheating: Since he is very close to Neko as well as Cherry (his ex-girlfriend), some of his In-Universe fans who ship him with one of these two accuse him of cheating whenever he's seen with the other.
  • My Fist Forgives You: After Joe comes clean about the cafe's criminal operations, Xenon forgives Joe on the condition that he gets to punch Joe whenever he wants.
  • One-Way Visor: Wears a futuristic helmet that wraps around his head and has a glowing red eye in the center.
  • Red Herring: An in-universe and out-of-universe example. Prior to Ivy's reveal, numerous small hints were dropped in the story that he was actually AEsir. These hints were also picked up by a few character in-universe, which led to his arrest. It was later revealed that Ivy deliberately planted a few of these hints to frame him and keep him from interfering with her plan.
  • Teen Genius: Gained a reputation online as a Robin Hood-like hacker using the handle X at the age of 15, before getting hired by ARC.
  • Teeth-Clenched Teamwork: Somewhat one-sided. ConneR more or less recruits him as an assistant for his research. ConneR does legitimately voice his respect towards Xenon's abilities, but Xenon can barely stand ConneR due to ConneR's condescending personality.
  • The Faceless: Somewhat downplayed. We only see the back of his head in every image where he doesn't have his helmet on. There are glimpses of the lower half of his face, but everything at eye-level remains obscured. His face, or rather a construct of him created by Ivy, is completely shown at the end of Neko's DLC chapter, and the look he has is ominous. In regards to in-game illustrations, it takes until the Crystal PuNK DLC for his face to finally be shown in full consistently.
  • The Hero: His official profile describes him as having a strong sense of justice. He works as a security administrator for ARC, and he is determined to find the identity of the perpetrator behind the mysterious AEsir incident. Unfortunately, due to Ivy's machinations, the ARC now believe he's AEsir, forcing him to go on the run. However, he does begin to live up to the typical character archetype when he saves a hospital under attack by drones.
  • The Teetotaler: Although he spends a lot of time at Joe's bar, Xenon does not drink. He only ever orders milk.
  • Tsundere: Amusingly, he fit the character archetype before he and Cherry started dating, going out of his way to hide his various acts of kindness towards her, such as throwing Cherry her first birthday party and picking her present based on his observations on what she secretly was interested in, and generally attempting to come off as a standoffish loner. He became a lot more openly affectionate towards her during their period as a couple, though he unfortunately seems to have reverted back a bit to his prior attitude in the present.
  • Vitriolic Best Friends: Xenon and Neko are as close as siblings. Xenon will also be the first to bring up how much Neko drives him up the wall.
  • White Hair, Black Heart: Downplayed. He's not necessarily evil, though it is implied that he's involved with a lot more shady activity than most initially thought. Then there's his possible connection to AEsir. He also has very pale hair underneath his helmet.
    • It is later revealed that he's completely innocent of the AEsir attacks and was framed by the actual perpetrator.
  • Working with the Ex: Works with Cherry, his ex-girlfriend, to investigate the virtual attacks that occurred following Aesir-FEST.



ConneR / Colin Neumann Jr. / Rald
A lecturer at The Academy and former archaeologist looking into the reconstruction of civilization who, following an incident that costs him his eye and hand, is hired by the ARC for his knowledge and skills. He's also a music composer, particularly noted for his insistence on using instruments discovered through his archaeological findings and refusal to perform virtually. This has given him a small but dedicated following.

Despite supposedly being placed in a fairly high position in the ARC, he finds himself locked out of a specific section of the central database called the Library. And so, he begins assembling a team to discover just what the ARC is keeping from him and many others. At the same time, he shows curiosity towards the apparent fallout of Aesir-FEST.

  • Adventurer Archaeologist: Used to be one of these, as detailed in his chapter's story. Of course, a lot of the "adventure" came from him operating outside of the law.
  • Always Second Best: Back during his days at The Academy, he always came in second place to a girl named Zoe Watson. He ended up developing feelings towards her as a result of this. He later meets her again after she's lost her identity, now going by Sasha. His feelings towards her keep him from just disposing of her even though he knew she was going to betray him.
  • Anti-Hero: Of the unscrupulous variety. His pursuit of knowledge is undoubtedly benevolent in intent, but he'll to go huge lengths to obtain whatever strikes his curiosity. He's more than willing to use others' talents for his own benefit, including going as far as to orchestrate a jailbreak just to free someone who can be of assistance to him. In the end, he doesn't really even care about the people he works with, just his own pursuits.
  • Artificial Limbs: Has a prosthetic eye as well as a prosthetic hand. He evidently lost his original ones in an encounter with the Architects.
  • A Spot Of Tea: He's actually more of German nobility, but a lot of his mannerisms bring more to mind the British gentleman. He also has a fondness for tea.
  • Badass Beard: It's a combination of well-groomed and rugged, befitting his image as a gentlemanly archaeologist.
  • Becoming the Mask: He was playing Sasha as much as she believed she was playing him, but admitted that he genuinely had developed actual feelings towards her.
  • Benevolent Boss: He is nothing if not courteous and friendly to his makeshift research team, routinely praising them for their abilities and generally attempting to hold meaningful discourse with them. He also breaks Xenon out of prison after Xenon is framed and imprisoned for the AEsir attacks. However, this is subverted when a journal log reveals that he in reality thinks very little of most of his team, as he refers to them merely as "toys" with the exception of Xenon.
  • Bishōnen: He had a pretty boyish-looking face in his youth.
  • Bitch in Sheep's Clothing: Downplayed example in the sense that he isn't secretly a villain, but a private journal log reveals that for all the kind words he says, he in reality thinks very little of even the ARC staff that actually respect him, outright referring to two members of his makeshift research team as "toys". Xenon seems to be the sole exception, and it's only because Colin values his abilities.
  • Blue Blood: The heir of the esteemed, wealthy Neumann family, who made major contributions in rebuilding the world hundreds of years ago.
  • Captain Ersatz: He's an academic professor who is also an archaeologist who often ends up fighting the local members of an authoritarian regime and has a complicated relationship with his father. Sound familiar?
  • Cool Teacher: He was a fairly popular lecturer at The Academy and is also an Adventurer Archaeologist.
  • Daddy Issues: He has a strained relationship with his father due to his father's growing irritability and the unrealistic expectations he put on him, not helped by his father's worsening dementia, which was in reality most likely a combination of him testing the family's ancient chip on himself and his PTSD from having encountered hostile Architects. Though he's an Empty Shell in the present, his father was able to compose a letter to ConneR during his period of lucidity apologizing to his son for the way he treated him and his mother and expressing his pride in what ConneR had managed to accomplish.
  • Determinator: He will go to any lengths to access the knowledge he seeks, even if that means breaking Xenon out of prison so that he can continue to make use of his abilities.
  • Eyepatch of Power: ConneR wears an eyepatch over his right eye, which was injured during one of his archaeological adventures. He wears it despite -nay, because of the fact that it was replaced by an advanced cybernetic eye- because he doesn't trust the ARC to not hack into and spy through it.
  • Genre Motif: Artcore/Orchestral
  • Gentleman Snarker: He maintains his polite, formal manner of speaking even when criticizing others. And he does this a lot.
  • Good Is Not Nice: For all his courteousness and charisma, ConneR is a straight-up Jerkass who has no problems using and abandoning people on a whim. If he wasn't ostensibly trying to do good by unearthing more of Earth's past, the way he acts would almost classify him as Ambiguously Evil.
  • Good Old Ways: As stated above, he refuses to perform any of his concerts virtually.
  • Hairstyle Inertia: Wore his hair exactly the same way over the course of his entire life as flashback logs indicate.
  • Hidden Heart of Gold: Colin is actually capable of caring about other people. It's just that it takes a lot for him to actually consider someone a loved one. He admits to Sasha that he becomes completely loyal to those he loves regardless of how much they may destroy themselves. Despite how much of a wreck his father became, Colin finds himself incapable of hating him.
  • Insufferable Genius: While clearly intelligent and well-respected for his archaeological work, Colin has no qualms about openly insulting others over their lower intelligence. Xenon outright calls him an asshole.
  • Like Father, Like Son: Like his father, Colin is an archaeologist, albeit a criminal one rather than part of an official sanctioned expedition team. Also like his father he was attacked by Architects, though he luckily managed to psychologically recover from it better than his father did.
  • Locked Out of the Loop: Despite supposedly having a fairly high position in the ARC, Colin finds himself locked out of certain sections that he should have clearance to. Clearly sensing something suspicious, he organizes his own research team to attempt to find out just what the higher-ups want to keep from him.
  • Manipulative Bastard: His pursuits are benevolent, but he is willing to use people like tools to get what he wants. He deliberately feeds false information to Cherry during the jailbreak to distract the prison's security system so that he can break Xenon out of his cell without any distractions. Needless to say, Cherry isn't happy to have been misled.
  • New Technology Is Evil: Subverted. Colin openly hates the fact that much of modern society is built upon advanced ancient technology which scientists have yet to fully understand.
  • Shipper on Deck: Explicitly calls Cherry Xenon's girlfriend even though they're exes.
  • Smug Super: He doesn't have any actual superpowers outside of his newly-acquired cybernetics that he barely uses, but he has an incredibly high opinion of his intelligence and charisma almost to A God Am I levels. Thing is, he's also incredibly capable at taking charge of situations and manipulating others, arguably doing much more to uncover humanity's past single-handedly than the ARC's entire scientific divisions.
  • Teeth-Clenched Teamwork: He makes it very publicly known that he does not trust the ARC at all, only working with them both because he realizes they are monitoring him and to further his own research.
  • Unwilling Roboticisation: Partially. After sustaining a grievous injury in an expedition, Colin has his hand and eye replaced with mechanical substitutes very much against his wishes. He suspects that the ARC is spying on him through his new eye.
  • Younger Than They Look: His time as an archaeologist has clearly taken a toll on him physically. He's in his thirties, but Cherry remarks that he looks like he's in his fifties.


Cherry / Sherry Pauline
Cherry as of Crystal PuNK
The lead singer of the band Cherry Punk, which is brought on to replace PAFF when the idol goes missing. She assists Xenon in clearing Neko's name after a hacking incident, and also works with him to investigate the source of the virtual attacks.

She and Xenon used to date when they were in a band called Crystal PuNK, but an unspoken incident led to them breaking up and the band breaking up with them. She seems to still hold the torch for Xenon years later.

It turns out that she is working for the Baro Brotherhood to get her father out of prison.

  • Action Girl: Proves to be pretty skilled with a pistol when facing down one of the Architects. Her marksmanship lead to her being hired by ConneR to help them shoot down drones while breaking Xenon out of prison. It turns out that she learned how to shoot from her father, Luis.
  • Affectionate Nickname: Back in her Crystal PuNK days, the other band members called her "Big Sis" despite her being the youngest member.
  • Amicable Exes: Remains friends with Xenon even after they broke up. Her reasons for contacting him again might not be completely benign however though she clearly wishes she could've just reconnected with Xenon without any complications.
  • The Atoner: Zig-zagged. She claims that she decided to contact Xenon and help him in his investigation after so many years of them being separated in order to repent for whatever incident led to them breaking up to being with. It's seemingly subverted when it's revealed that she was The Mole for the Baro, sent to keep Xenon from interfering in their operations. However, she goes on to participate in breaking Xenon out of prison after he's framed for the Aesir attacks even though Xenon being behind bars greatly benefits the Baro. It's also made very clear that she feels genuinely guilty for whatever happened all those years ago. It's only as she's dying that she manages to finally make peace with her past.
  • Boyish Short Hair: Wears her hair like this in the present, which matches her personality. During her Crystal PuNK days, she had more of a bob cut.
  • Broken Bird: She said to Xenon that there are parts of her past that she's uncomfortable sharing. It's significant being that she told him this after stumbling onto his doorstep dressed up in clothes she clearly didn't pick for herself. The fact that she cried into his chest afterwards leads to a lot of uncomfortable implications.
  • Curtains Match the Windows: Has cherry-red hair and eyes.
  • Daddy's Girl: From what little we see and hear, Cherry seems to be close to her father. She's close enough to him that she's willing to work for a ruthless organization like the Baro Brotherhood to shorten his prison sentence.
  • Dark and Troubled Past: Her mother was killed by a malfunctioning ARC drone, which left her father as her sole caretaker. Though he loved her, he also struggled to support her, leading him to being frequently absent. Several aspects of her past are left ambiguous, but it's implied that her father also became involved in less reputable business with her following in suit. At this point, she's been involved with the criminal world for so long that she no longer believes she's even a good person.
  • Famous Last Words: "...Haha... Your"
  • Genre Motif: Indie Rock as Cherry. Crystal PuNK has more metal songs.
  • Heroic Sacrifice: She puts herself into the drone's line of fire to destroy the entire network of drones attacking her and her friends. The bullet proves to be fatal.
  • Killed Off for Real: Is confirmed to have died in the 2.7 update.
  • Lady Drunk: She has an obscene level of tolerance to alcohol. She's apparently been drinking since she was a teenager.
  • Like Father, Like Son: Or "Like mother, like daughter". Both of them end up losing their lives to ARC drones.
  • Love Will Lead You Back: She was in a relationship with Xenon before but an incident led to them breaking up. She is very clearly interested in them getting back together and routinely makes the suggestion while working with him, but Xenon refuses to approach the topic.
  • Missing Mom: It's heavily implied, and later confirmed, that her mother was killed by a malfunctioning ARC drone. Of note is that it was one of the first recorded instances of a drone harming a civilian.
  • The Mole: The Baro have tasked her with keeping tabs on Xenon. She really isn't happy about this.
  • My Greatest Failure: She heavily implies that she was involved in whatever disrupted Shannon's memories and led her to close herself off to the outside world. Seeing Shannon's fragile mental state in the hospital causes her to weep.
  • Replacement Scrappy: In-Universe example. The Puffs were not pleased when it was announced that Cherry Punk would be replacing PAFF. When the riots broke out following the termination of PAFF's contract, she ended up getting injured.
  • Sacrificial Lion: Her death shows just how dangerous the situation has become for everyone.
  • Single Woman Seeks Good Man: The reason she fell for Xenon and still holds the torch for him years later is because of how observant and considerate Xenon was of her interests including her secret love of cute things.
  • Sins of Our Fathers: One of the reasons she and Xenon never fully reconciled seems to be that Cherry's father killed Xenon's father.
  • Stepford Smiler: Acts like an outgoing young woman, but there are a number of hints of things in her past that still burden her years later.
  • Tomboy with a Girly Streak: Cherry can drink as much as the guys can and gravitates towards shooting games at the arcade. She also has a fondness for cute things such as the necklace Xenon gave to her during her first actual birthday party, something that Joe commented didn't match the image Cherry presented.
  • Triple Shifter: She attempts to juggle her time as a professional musician with her time assisting Xenon in his investigation, as well as being an intermediary for the Baro. Needless to say, this has somewhat negatively affected her career, as she's criticized for her increasingly frequent lateness to concerts and practice sessions. Needless to say, eventually her role as a professional musician ends up falling by the wayside, with her now on the run with Xenon.
  • Unwitting Pawn: During their rescue of Xenon, ConneR tricks her into triggering the security system to distract the drones and agents while he frees Xenon unimpeded. He proceeds to rob her of her gun and use the threat of the ARC's security forces to conscript her into his cause. Needless to say, Cherry isn't happy with this.
  • Working with the Ex: Works with Xenon, her ex-boyfriend, to investigate the rash of virtual attacks that followed Aesir-FEST.
  • You Gotta Have Blue Hair: Her hair is a particularly distinct kind of red.


Joe Miller
The owner of JOEZ Cafe, who was once in a band with Xenon and Cherry called Crystal PuNK. He inherited control of the cafe from his uncle, along with the responsibility of mediating between the many gangs active in the area.

Unfortunately, Joe isn't quite as skilled as his uncle at navigating the criminal underworld, and he ends up under the employ of the Baro Brotherhood, a dangerous gang rapidly rising in power. His attempt to get out of the criminal life leads to the death of his beloved dog Zark and the implicit threat of death for the rest of his loved ones. Just when things are looking hopeless, Xenon suddenly comes back, revealing that he's investigating the Baro's human trafficking operations...

  • The Atoner: Reveals the cafe's entire operation to Xenon so Xenon can investigate the case of a kidnapped girl named Ringo, a trafficked girl Joe had failed to save.
  • Book Dumb: His performance at The Academy is never really brought up, but he outright admits he's not really that smart. Saxon noted that Joe has talent in physical skills such as bass playing and drink mixing but isn't necessarily the best at thinking things through.
  • Butt-Monkey: Things rarely go his way. If he's not being shown up by other characters or made the butt of jokes, he's the one getting beaten up. Out of all the main characters in fact, he probably suffers the most physical abuse.
  • Disappeared Dad: His mother is brought up a few times. His birth father never is.
  • Dreadlock Rasta: Wears his hair like this.
  • Embarrassing Nickname: During Cherry's birthday party, he got drunk and ran through the streets proclaiming himself the "King of Germs". The nickname ended up sticking to his chagrin.
  • Failure Hero: After letting Diego manipulate him for so long, Joe finally decides to intervene on a human trafficking exchange. All it results in is his dog getting killed, him getting injured, and Diego implicitly threatening his loved ones. And the trafficked girl ends up getting exchanged anyways.
  • Fatal Flaw: His interest in money leads him to giving certain gangs more leeway in their operations for the sake of making some extra cash. It allows the Baro Brotherhood to act on their dangerous ambitions, disrupting the very balance Saxon sought to preserve.
  • Genre Motif: Jazz/Funk
  • Good Scars, Evil Scars: Has two parallel scars near his left eye and a horizontal one over the bridge of his nose, befitting his criminal dealings.
  • Horrible Judge of Character: Doesn't pick up on how dangerous and manipulative Diego is despite being warned prior.
  • Idiot Hero: Outright admits that he isn't good at thinking long-term. Deconstructed as it is what allows the Baro to grow in power.
  • Jerk with a Heart of Gold: He's a braggart and a bit of a hot-head, but he's also a loyal friend to Xenon and Cherry. He also extends this loyalty to Neko, offering her and Aroma a safe haven if Aroma is ever discovered.
  • Knowledge Broker: He also provides clients with information on certain individuals.
  • Like Father, Like Son: Technically uncle, but Joe treated Saxon like a father anyways. Besides directly inheriting cafe and the responsibility of dealing with the organized crime in his area, he also ends up becoming part of a fairly successful band just like his uncle did back in his youth.
  • Manchild: Is rather naive and trusting of others in a way that's almost child-like. He easily falls for the manipulations of others, assumes that those who are nice to him are friends, and seems completely oblivious to the kind of dirty business the criminal underworld entails. It's honestly little wonder why he gets along with Neko. It finally sets in just how dangerous his life is and just how carefully he needs to tread after Zark is killed.
  • Nice Job Breaking It, Hero!: Accidentally leaks the list of the Ando gang's top brass, leading to a mass of arrests that allow the ruthless Baro gang to rise in the ranks.
  • Secret Keeper: He's aware of Cherry's dealings with the Baro but seemingly never disclosed this to Xenon.
  • Small Name, Big Ego: Often proclaims himself to be the master of whatever activity he's participating in only to be shown up immediately.
  • Trapped in Villainy: His ultimate fate at the end of his chapter. Though he didn't plan for it, Diego uses the unceremonious killing of Zark to deliver the message to Joe that he can never escape his employment.


Nora / 009 / Shizuka Shiino
A Child Prodigy who created ROBO_Head. She was trafficked by the Mogura crime organization as an infant under the label 009, before becoming a guinea pig for the cruel experiments of a group of deranged researchers called the "Ravens". After being deemed a failure, she was left to die to a fatal virus called "The Ender" but miraculously survived. She was found by Phoenix, who adopted her under the name Nora so that he could research her role as possible a cure for the Ender virus.

She can read digital information through her brain, an ability nicknamed "The Eye of Horus", which the Mogura used as a kind of fortune telling. It was her fear of the many criminals who abused her abilities that motivated her to create ROBO_Head, who would be her and Phoenix's protector. After a member of the Ravens named Kim attempted a violent takeover of the criminal underground, she and ROBO_Head fled, with Nora leaving ROBO_Head behind on a train to Node 08 to bring happiness to others.

Nora's final fate is unknown, though she tells ROBO_Head that she intends to use her abilities as a bargaining chip when the Mogura inevitably track her down.

Before he collapsed from his injuries, Phoenix revealed to Nora that her real name is Shizuka Shiino. Noah, Phoenix's former subordinate, was intended to be her new guardian.

In the present day, she's become the chief of the Kyuu Hou Kai, Phoenix's research team.

  • An Arm and a Leg: Lost her original legs as a consequence of the Ravens' experiments.
  • A Child Shall Lead Them: She is the current head of the Kyuu Hou Kai.
  • Artificial Limbs: Has two mechanical legs due to her original legs having to be amputated.
  • Because You Were Nice to Me: Considers Phoenix her father because he saved her from a life as the Raven's test subject and took care of her. She is willing to defend him despite the fact that he's been involved in a lot of unethical research in his own right.
  • Broken Bird: Since she was an infant, she's been subjected to horrifying abuse and forced to participate in horrific acts of crime. Needless to say, her view of human morality was colored way earlier than most. It's seemingly gotten worse in the intervening years, with Nora having become a much colder person in the present.
  • Cast from Hit Points: As it turns out, using her power puts a major strain on her body. In the present, continued use of her power has caused her to go blind.
  • Child Prodigy: She is incredibly intelligent for her age, having created ROBO_Head's prototype at the age of five. It's implied that her intelligence is tied to her unique brain waves, which Phoenix hypothesizes are what give her immunity to the Ender virus.
  • Cruel to Be Kind: When ROBO_Head returns to Node 03 and meets with her again, she threatens to destroy ROBO_Head if he doesn't leave. This is to protect both ROBO_Head and the Kyuu Hou Kai from the Mogura.
  • Emotionless Girl: It was actually noted in-universe that she rarely exhibited any emotions even as an infant. One of her reasons for creating ROBO_Head's prototype was to practice simulating emotions. Ultimately subverted by the end. Though she physically can't express her emotions, she does sincerely tell ROBO_Head during their last conversation that her time with him were some of the happiest of her life. In the present day, however, she's seemingly become emotionless for real, though she still is a compassionate person deep down.
  • Every Girl Is Cuter with Hair Decs: Wears two small machine-like hair clips. She still has them when we see her in the present.
  • Forced into Evil: Phoenix is her adopted father, but the Mogura for all intents and purposes own her. And they are more than willing to dispose of her and her loved ones if she doesn't perform her duties as The Eye of Horus.
  • Genre Motif: Hardcore Techno/Dubstep, the same as her creation ROBO_Head.
  • Give Him a Normal Life: A variation. She leaves ROBO_Head on a train and gives him specific commands to never look into her so that he can live his life free from the burdens that will always hang over her.
  • Harmful to Minors: Basically her entire life in a nutshell. As an infant, she was subjected to all manner of inhuman experiments. As a toddler onward, she was forced to play a role in some very nasty criminal activity. This resulted in her discovering the dark side of humankind far sooner than any child probably should.
  • Heroic Sacrifice: Stays behind to placate the Mogura so that ROBO_Head won't be scrapped for killing Lam.
  • Hidden Depths: Besides being incredibly intelligent in the field of science and robotics, she also has a surprising interest in music, having begun composing when she was still a toddler. This interest is something she passes on to ROBO_Head. ROBO_Head is rather heartbroken when he meets her in the present day and realizes that she's stopped composing.
  • Ill Girl: The strain of using of her power has left her body in a more fragile state.
  • Meaningful Name: Her name means "honor" in Latin. Phoenix intentionally chose this name as he believed Nora would signal the next step in human expansion.
  • Morality Pet: Served as this for the otherwise amoral Phoenix. It was as a result of their father-daughter bond that Phoenix came to regret his actions.
  • Parental Abandonment: Her birth father sold her to the Mogura when she was an infant.
  • Psychic Nose Bleed: This happens whenever she uses her "Eye of Horus" power.
  • The Immune: Is immune to the Ender virus, a factor which saved her from being disposed of as a baby. She later reveals that she isn't so much immune to the virus so much as her body has somehow adapted to coexist with it. Her Eye of Horus powers are theorized to be a result of this coexistence.
  • She Is All Grown Up: In the present, she has grown into a beautiful if cold and hollow young woman.
  • The Speechless: Is seemingly incapable of speaking. In order to communicate both her words and her emotions, she uses ROBO_Head's prototype, Unit 01.
  • Technopath: She has the ability to stream digital information through her mind including data and live camera feeds.
  • Took a Level in Jerkass: She's a lot colder when we meet her again in the present, outright threatening to destroy ROBO_Head when he returns to Node 03 if he does not follow her command to leave. It's later revealed to be more of a Jerkass Façade to keep ROBO and her team safe.
  • Trapped in Villainy: It doesn't matter how far she runs. The Mogura will find a way to track her down. It's why she opts to leave ROBO_Head on a train to Node 08.
  • When She Smiles: In the opening cinematic that came with the 2.0 update, she can be see faintly smiling when she sees ROBO_Head performing music for a livestream.
  • Wise Beyond Her Years: Besides her general genius-level intellect, she's unnervingly composed and mature in general. Her reasons for leaving ROBO_Head behind are philosophically remarkably nuanced.
  • You Are Number 6: When she was being trafficked as an infant, she went by the designation 009.
  • Younger Mentor, Older Disciple: After Aroma reveals that she has abilities similar to Nora, Nora takes it upon herself to mentor her in properly using her powers so she doesn't end up permanently damaging herself with the side effects like Nora had done.
  • Younger Than They Look: Taking the math into account, Nora would be 12 in the present. She definitely looks a bit older than that, though that could just be a result of her powers taking a toll on her body.


AEsir / Ivy

An Architect, one of the robots tasked with preparing Earth for the awakening of humanity hundreds of years ago. Upon regaining consciousness in the middle of an ancient ruin, she set out to find her friend Vanessa.

Upon discovering that Vanessa was being used as the core for the cyTus system, she evolved her goal towards creating a completely new cyTus system, one that would free Vanessa.

During the course of her mission, she harnessed the power of raw emotion to create music, becoming the legendary DJ AEsir.

  • Anti-Villain: She wants to free Vanessa from captivity and create an improved cyTus system in the process. However, her means of doing so involves invading the minds of numerous innocent humans for "data", which causes great mental distress at best and actual damage at worst. After successfully awakening Vanessa, she says she no longer wishes to harm humans.
  • Arch-Enemy: Views Xenon as the biggest threat to her progress due to his ability to trace her attacks. This is why she framed him.
  • Barbie Doll Anatomy: On account of being an android, she lacks nipples and genitalia.
  • Big Bad: As the orchestrator of Aesir-FEST, she is responsible for much of the damaging fallout that followed, though she definitely isn't the most traditionally villainous character in the story. She's seemingly no longer this after successfully awakening Vanessa as she's seemingly dropped all her "villainous" qualities.
  • Deadpan Snarker: She speaks in a rather dry and bitter tone in her logs especially when dealing with evidence of human ignorance.
  • Eating Machine: Despite being a robot, she requires food in order to continue functioning.
  • Emotion Eater: A variant of the trope as she does not directly feed on emotions. Rather, she extracts emotions from humans like data, which she intends to use to create the new cyTus system.
  • Everyone Has Standards: She's somewhat ambivalent when it comes to the livelihood of humans, but even she disapproved of The Blessed's plans to eradicate humankind, and that was before she found out Vanessa was going to be used as a glorified suicide bomber.
  • Exotic Eye Designs: Her left eye has an unusual white circular pattern inside it.
  • Famed In-Story: A legendary DJ who amassed a huge following in just two years.
  • Fembot: She looks like a human girl with some mechanical components pasted on.
  • Gaslighting: Manipulates Xenon's memories so that he believes he is AEsir in order to keep him from interfering.
  • Genre Motif: Assorted Electronic Music with an emphasis on Artcore.
  • Heel–Face Turn: Pretty much loses all of her villainous aspects after she succeeds in awakening Vanessa. She even goes out of her way to defend humanity after Vanessa is revealed to have developed a Humans Are Bastards mindset.
  • Horns of Villainy: Not on Ivy herself, but her hoodie and virtual avatar as AEsir have very prominent pink horns.
  • Humans Are Morons: Holds this view, generally expressing annoyance at mankind's ignorant appropriation of Architect technology and inaccurate accounts of the past.
  • Humans Are Special: Despite the above, she also believes this, which is why she's opposed to the Blessed's plans to eradicate them. To Ivy, humans are far too complicated to be simply generalized as "evil". She did harm thousands of people to rebuild the cyTus system and awaken Vanessa, but upon succeeding, she states that she has no desire to harm humans any further.
  • In the Hood: Wears a baggy hoodie that obscures her more mechanical features.
  • Me's a Crowd: Can create duplicates of herself, which she uses to carry out some of her operations. These duplicates are noticeably more machine-like in their behavior and exist only to follow her commands.
  • Noble Demon: Ivy has no problem with creating long-lasting mental damage to users of the iM system in order to achieve her goal of awakening Vanessa, but she also leaped off a tower without hesitation to save a young girl from accidentally falling to her death. Her harming humans was also purely a means to awaken Vanessa, and upon succeeding, Ivy says she doesn't wish to harm them further.
  • Recycled Soundtrack: Three of her songs are taken from the first Cytus game. Makes sense considering her link to the central character of that game.
  • Red Eyes, Take Warning: The visor of her helmet projects two narrow, demonic-looking red eyes. Her Architect form also has red eyes.
  • Ridiculously Human Robots: As an Architect, she looks virtually indistinguishable from a normal human with only a few mechanical components visible.
  • Samus Is a Girl: AEsir has a male-coded mechanical form, but her true form, Ivy, is distinctly feminine.
  • Shadow Archetype: She's essentially Xenon's "X" persona if it became an independent entity, but without most of Xenon's moral restraints. Like X, she routinely undermines the ARC's security for the sake of achieving a greater good. However, unlike Xenon, who cares about the individual, she is solely focused on the end goal and will harm innocent people if it allows her to accomplish it. Tellingly, the person who filed the formal accusation of Xenon being AEsir was under the belief that one of Xenon's AIs had decided to pick up where Xenon had left off as X.
  • Smug Super: She takes a degree of pride in her capabilities as an Architect, something that comes through in her personal logs and even the comments she makes on the results screen of her songs.
  • Spanner in the Works: She could care less about what Aroma is going through other than the emotional data she provides, but her interference with everyone's memories in Aesir-FEST did cause Aroma's original memories as Kaori to reemerge, which likely disrupted the plans of the individuals who had turned her into the original Aroma's replacement.
  • The Bad Guy Wins: As of 2.0, Ivy has apparently achieved her goal of awakening Vanessa, memory-wiped the only person who was close to discovering her true identity, and framed him for the crimes she committed.
  • Undying Loyalty: To Vanessa. She fought against The Blessed despite her being deemed one of them simply because Vanessa was not considered worthy. In the present, she enacts her plans for the main purpose of freeing her.
  • Villain Protagonist: Her chapter was released with the 2.0 update.
  • Walking Spoiler: Considering the fact that her identity was a secret and subject to multiple theories before the 2.0 update, she's definitely this.
  • Well-Intentioned Extremist: She seeks to create an improved cyTus system that will both benefit mankind and free Vanessa, but to do so, she is willing to harm hundreds of people to obtain the necessary data.
  • White Hair, Black Heart: Her hair is completely white, and she's the main antagonist. Played With in that she isn't necessarily "evil", though she is somewhat ambivalent to the mental pain her information gathering sessions cause. Subverted after Ivy awakens Vanessa, as Ivy states that she doesn't wish to harm any more humans and also attempts to discourage Vanessa's newly-developed Humans Are Bastards mindset.
  • You Are Number 6: Her serial number is 2501_IV. She derived her name Ivy from the last two digits of this number.


Hatsune Miku 2.3.9
The flagship Vocaloid and Cytus II's first guest character. Within the game's universe, Miku is the latest version of cyTus system's first virtual idol. She is part of what her creator, Furuhata, refers to as the "Raising Procedure", a project to develop virtual personalities with a sense of realism. Following an incident with the cyTus system itself, she begins to become something more than just a virtual personality...
  • Ascended to a Higher Plane of Existence: Possibly? It's left ambiguous if she was simply deleted or gave up her physical form through another method and still exists in the cyTus system in some form.
  • Bare Your Midriff: Her idol outfit exposes some of her stomach.
  • Benevolent A.I.: Even after discovering her true nature and just how expendable she is, Miku only wants to continue living so she can make others happy through her music. And she ultimately allows herself to fade so that her next iteration can continue making others happy.
  • Curtains Match the Windows: Has teal blue hair and eyes.
  • Dead Man Writing: She leaves one last sound file for her creator Furuhata thanking him for creating her.
  • Disappears into Light: During her final concert, she fades out like this.
  • Flat Character: Justified given that she is a program and not a human being. This also ties into the general Hatsune Miku mythos which leaves her personality mostly undefined.
  • Girlish Pigtails: She wouldn't be Miku without them.
  • Go Out with a Smile: She either passes on or ascends doing what she loves: singing for her fans.
  • Grew Beyond Their Programming: Following a severe glitch in the cyTus system, most likely caused by Ivy, she becomes aware of her existence as an Artificial Intelligence, gaining a fully-developed consciousness in the process. Unfortunately, the process that led her there was messy enough that Furuhata believed it to be a sign that she needed to be replaced and updated. By the time Furuhata finally realizes Miku has become fully sentient, Miku's already been replaced.
  • Idol Singer: Even moreso than PAFF, she's practically an embodiment of the archetype and surrounding culture, being literally created to be a marketable icon with nearly every aspect of her personality being a construct to appeal to people. She even has the typical bubbly personality unlike PAFF.
  • Meaningful Name: Or rather "meaningful numerical designation". 3 and 9 in Japanese can be read as "Mi" and "Ku".
  • Nice Girl: She's a legitimately sweet girl even after she is exposed to some unsavory truths about her true nature.
  • Nonstandard Character Design: Her character portrait is the only one that's completely colored.
  • Projected Man: She is a construct of the cyTus system and can only be viewed and interacted with in virtual space, but can also be projected as a hologram.
  • Rapunzel Hair: Though not as long as they usually are, her pigtails still go down past her hips.
  • Ridiculously Human Robots: She looks and interacts with the world like a completely normal girl. She doesn't even slip into Spock Speak whenever she talks.
  • You Gotta Have Blue Hair: She has teal hair, which in this case is an indication that she's an artificial being.
  • What Measure Is a Non-Human?: The crux of the conflict in her story is the fact that she's treated as a replaceable simulation of a person rather than a fully-actualized being herself even after she develops self-awareness. She ultimately has to accept her role as just a stepping stone for a future iterations of herself, though she goes out on her own terms.

Secondary Characters


Helena Black (née White)

Aroma's older sister, and her manager under Monophonic. A hardworking young woman who wants the best for Aroma.
  • Adult Fear: After the car accident, Helena had to watch over Aroma's comatose body, not knowing if her sister would ever wake up. Aroma then wakes up only to not recall anything about her past, barely even recognizing Helena. And then years later, Aroma runs away, which Helena believes was caused by how she treated her. There is also the fact that her sister gradually became more alien to her after her memories as Kaori reawakened.
  • The Atoner: After Aroma's original memories as Kaori reawakened, Helena's guilt finally boiled over, and she intended to tell Aroma the truth about her identity, not caring if Aroma would hate her for it. Unfortunately, Aroma ran away before she got the chance. She redeems herself more fully by refusing Noah's offer to scrub Aroma's memories all over again and personally driving Aroma to JOEZ Cafe to hide out.
  • Aw, Look! They Really Do Love Each Other: Most of the time, Helena seems to treat her husband Noah as more of an annoyance, generally not paying any attention to his ramblings about what his department discovered. However, she readily accepted the comforting words he gave her both when she was watching over Aroma while she was comatose and when Helena found out Aroma had run away. Sadly, this was a one-sided affair as Noah was obsessed with Aroma instead.
  • Cool Big Sis: She clearly cares a lot for Aroma, even becoming her agent to ensure that she would be able to keep her safe during her idol career.
  • Dramatic Irony: She has called Noah's compliments of Aroma's appearance creepy, not realizing that Noah has a legitimately threatening obsession with Aroma.
  • Irony:
    • She became Aroma's manager to protect her from Mono's potentially predatory practices not realizing that the most threatening predator was her own husband.
    • On a more tragic note, she allowed Kaori to be turned into Aroma's copy so that Aroma could have a second shot at life. Helena then becomes so terrified of losing her again that she isolates Aroma from her friends and keeps her from making new ones, basically robbing Aroma of the chance to actually live her second life.
  • It's All My Fault: Blames herself for Aroma running away because of her involvement with Kaori's memory wipe.
  • Knight Templar Big Brother: A gender-inverted example. When it was confirmed that the original Aroma wouldn't survive following the car accident, she reluctantly agreed to let Noah turn Kaori into her duplicate. However, after Kaori's original memories return, the guilt finally prompts her come clean. By that time, unfortunately, Aroma had already run away.
  • My Beloved Smother: Helena is somewhat overprotective and controlling of her sister, repeatedly keeping Aroma in the dark about Mono's various internal politics and generally acting as a barrier for those who were interested in meeting Aroma, basically just telling Aroma to focus on her singing rather than establish any life outside her career. Neko ended up initially getting the wrong impression of Aroma because Helena quietly kept Aroma from talking with Neko personally, even when they were in the same space. It's revealed this was born out of a fear of losing Aroma again, as well as her own guilt over being involved in erasing Kaori's identity.
  • Parents as People: Of the substitute variety. Though she clearly cares about Aroma, there are times when she seems more invested in Aroma's career than her emotional well-being. She can also be very controlling of her sister, which partially led to Neko getting the wrong impression of Aroma.
  • Parental Substitute: Was this for Aroma when they were younger, working three jobs to support the two of them.
  • Skunk Stripe: Has a large white streak along her right bang.
  • Sugar-and-Ice Personality: Generally gives off the vibe of being a distant and calculated businesswoman even when around her own sister, but there are also moments when she is incredibly affectionate towards Aroma.


Noah Black

Helena's husband and current director of the ARC's technology department. A seemingly composed man who cares about his wife and sister-in-law's well-being. He seems particularly invested in Aroma's career. He was also the former subordinate of Phoenix Wyle, the former director of the ARC's technology department, and may have been the reason Phoenix was relieved of his position.

  • Adult Fear: He embodies this for both Helena and Aroma. That dorky, uninteresting husband of yours could in reality be a disturbing predator fixated on your teenage sister. That man you viewed as a father could be viewing you in a much less familial way.
  • Bait the Dog: Is presented at first as a loving husband who also gets along well with Aroma and is supportive of her career. Then we go further into Aroma's story, revealing that Noah seems to have a disturbing fixation with Aroma in general. He also was the one who forcibly turned Kaori into Aroma's replacement, strong-arming his wife into being complicit in the process.
  • Beneath the Mask: He acts much more composed when he's around Helena and Aroma. Emphasis on acts.
  • Ephebophile: Is heavily implied to have lustful, obsessive feelings towards Aroma. These feelings were first revealed when Aroma was 16.
  • Even Evil Has Loved Ones: His obsession with Aroma takes precedence, but when he's kidnapped, he actually becomes enraged at the thought that his kidnapper hurt Helena. So he does care about his wife on at least some level.
  • Fan Boy: Jokingly refers to himself as Aroma's number one fan but turns out to be a rather obsessive one in a more serious way.
  • Heel Realization: Multiple reveals put him in a very unsavory light, but upon finding out that Aroma ran away, he curses himself in private, expressing the desire to "repent". It's revealed that he considers "rescuing" Aroma his repentance, even if his means of doing so involves stealing the life of another girl.
  • Ignored Epiphany: He seems to realize just how wrong it was for him to turn Kaori into Aroma's replacement and comes clean to her about trying to erase her memories. Then, while Aroma is resting, he reveals to Helena that he intends to wipe her memories permanently.
  • In Vino Veritas: Noah first reveals the much darker aspects of his character when he stumbles into the White household while drunk.
  • Irony: Phoenix forbade Noah from following him after Phoenix was relieved of his position, believing that the amoral world he was going to enter for the sake of his research would corrupt his young subordinate. Noah either was already corrupt or ended up becoming corrupt later on anyways, misusing Phoenix's own technology for arguably more selfish purposes.
  • It's All About Me: Even when he's attempting to repent, he pretty much glosses over the fact that he'll be erasing an innocent girl's identity. It doesn't matter to him because he loves Aroma that much. Never mind the fact that his wife, Aroma's own sister, was reluctant to go through with it.
  • Jerk with a Heart of Jerk:
    • He's not as repentant about sexually assaulting Aroma as he claims to be. See Perverted Sniffing.
    • He gets yet another moment after seemingly finally coming clean to Aroma about her in reality being Kaori, profusely apologizing for what he did to her while he was drunk. He insists that he only did so to return things to their old family dynamic, but then, after Aroma falls asleep, he reveals to Helena his intentions to permanently delete Kaori's memories. There's also the fact that he drugged Neko's father, an innocent man, just to have this conversation.
  • Perverted Sniffing: After seemingly attempting to apologize to Aroma for whatever he did to her while drunk, claiming to have no memories of the event, he sniffed the hand that made contact with her, chuckling to himself that he came on to her too quickly, showing he was not repentant in the slightest.
  • Rape Is a Special Kind of Evil: He attempted to sexually assault or rape Aroma when she was 16. He was so drunk at the time that he passed out before he was able to go through with it, but judging by Aroma's scream and how she acted towards him afterwards, the intent was very clear.
  • Theme Naming: His wife and sister-in-law's last name is White, and his last name is Black. Might also count as Meaningful Name considering what kind of man he's been revealed to be.
  • Walking Spoiler: He's not the kind man and loving husband he's initially presented as.
  • Well-Intentioned Extremist: Viewed Phoenix's technology as a means for humanity to gain true immortality, via the transfer of mind and body into new vessels. His research was banned as the transfer of memories was considered too dangerous a concept.
  • Your Cheating Heart: It's heavily implied he attempted to sexually assault Aroma while drunk even though he was already married to Helena by that point. He also drunkenly stated that he prefers Aroma to Helena. Keep in mind, Aroma was 16 at the time.



The boss of the Baro Brotherhood. He is affiliated with Joe, using Joe's cafe as a smuggling zone. He's actually a member of the Mogura, an incredibly powerful crime organization from Node 03 and the ringleaders of the entire human trafficking trade.

  • Affably Evil: For a guy involved with human trafficking, he's remarkably laid-back and friendly. It could just be a means of manipulating Joe, though he does seem to prefer persuasion over violence. He leans back into Faux Affably Evil with his orchestrated attack on the Kyuu Hou Kai, him retaining his casual tone as he orders the deaths of numerous faculty and patients.
  • Ambition Is Evil: Seeks to establish a new order with his gang at the top.
  • The Dreaded: He's the reason the Baro is so feared.
  • False Friend: To Joe. All of his kind words and generous offers of cash are just a means to manipulate Joe into giving the Baro more leeway to reshape the criminal underworld how they see fit.
  • Not So Different: Claims he and Joe are this. Again, it's probably just a manipulation tactic.
  • Pragmatic Villainy: Voices his objections when his subordinate Hunter kills Joe's dog, Zark, knowing it'll make it harder to manipulate Joe.
  • Teens Are Monsters: According to him, he's been in the business since the age of 15.
  • The Starscream: He reveals to Joe that he ascended to the position of boss by getting his boss arrested.
  • Villain Respect: Even though Joe's uncle was what kept him from establishing a proper foothold in the criminal underworld, Diego considers him a great man. Of course, he could've just been saying that to manipulate Joe.


Kouhei Asakura

Neko's father and Saku's ex-husband, who moved to Node 08 with Neko for a more lucrative job. He's a rather blunt man who has difficulties connecting with his increasingly rebellious daughter, a problem that becomes more apparent after he marries Yukiko, a colleague from work.
  • Abusive Parents: When Neko was a teenager, he edged slightly towards this after Neko insulted Yukiko one too many times, physically striking Neko. In general, he was pretty pushy in regards to getting Neko to accept Yukiko as her new stepmother. It takes a while for both him and Neko to come around to reconciling afterwards.
  • Amicable Exes: With Saku. They still communicate with each other about their lives despite being divorced.
  • Anger Born of Worry: He was very livid when a teenage Neko suddenly returned home after disappearing for days on end following an argument over dinner. That anger likely came from the very Adult Fear of his child disappearing for a long period of time without calling back. Of course, his poor handling of said anger led to Neko becoming The Runaway and leaving for an even longer period of time.
  • Brutal Honesty: He's not a man known for his tact. Without even mincing words, he informed an eight-year-old Neko that he and Saku were getting divorced. Saku obviously called him out on it.
  • Happily Married: For all intents and purposes, his marriage with Yukiko is a very happy one to the extent he considers her and her son Kenta as much a part of his family as Neko. Neko really wasn't a fan of this as a teenager.
  • Has a Type: Neko reluctantly remarked how similar Saku and Yukiko actually are, despite how much she disliked Yukiko at the time.
  • Hidden Depths: According to Saku, he does really like the music Neko creates even though he doesn't quite understand it. The reason he criticizes Neko's musical tastes is because of his general frustrations with her rebelliousness.
  • Papa Wolf: He stormed a building of loan sharks after they attempted to kidnap Neko and Kenta on top of hounding Yukiko. With a little help from Neko and, unbeknownst to him, Xenon, he cleared out the entire building by threatening to painfully detonate the chips of the loan sharks. He didn't even realize he had suffered a minor head injury until it was pointed out to him. For all his faults as a parent, he does legitimately love his family.
  • Parents as People: He took the job at Node 08 to support his family, and he does indeed love his daughter. Unfortunately, he conveys this love through his constant worries of what Neko gets up to when she's out of the home, which Neko took as him just hating everything that she did. When Neko was a teenager, there were also times when he seemed to care more about Yukiko than his own daughter.
  • Shipper on Deck: During a dinner conversation, he asks Neko why she and Xenon haven't started dating yet. A flustered Neko dismisses this as Kouhei being slightly tipsy.


Yukiko Asakura

Neko's stepmother and Kenta's mother. Despite being a kind woman who wants to be a proper mother to Neko, Neko had serious problems with her taking the place of her birth mother.
  • Dark and Troubled Past: Implied. She's a single mother who is in debt to a group of very bad loan sharks, who're willing to resort to child kidnapping to get their payments. There is no mention of Kenta's father, but the implications of his absence aren't good.
  • Gold Digger: Neko accused her of being this after finding out about her financial situation. Though Kouhei was indeed helping her to sort through things with the loan sharks, Yukiko does sincerely want to be a good mother to Neko.
  • Happily Married: Does legitimately love Kouhei and the family she's become a part of.
  • Nice Girl: For all intents and purposes seems to be a sweet woman who wants to be a good mother and wife.
  • Parent with New Paramour: Neko didn't really have a problem with Yukiko until Kouhei revealed that he and Yukiko were getting married. Despite Yukiko's attempts to connect with her stepdaughter, Neko saw those attempts as Kouhei betraying Saku. Neko later does accept Yukiko into her life after helping Kouhei deal with her loan sharks.
  • Shipper on Deck: Like her husband, she thinks Neko and Xenon would make a cute couple.


Saku Shiraishi

Neko's mother and Kouhei's ex-wife. Kouhei and her separated as she did not want to leave her family in Node 03 behind. Neko is very close to her.
  • Amicable Exes: With Kouhei. Despite being divorced, they still discuss their respective lives with each other. She even encourages Neko to reconcile with Kouhei even though she acknowledges his faults.
  • Connected All Along: Kaori was one of the orphans she helped raise in Node 03's orphanage.
  • Good Parents: Was a very loving mother to Neko, which is why Neko is so close to her and why she had difficulties accepting Yukiko. She was also this to Node 03's orphans as the orphanage's caretaker.
  • Nice Girl: Is a kind and caring mother who bears no ill will towards her ex-husband. She is also very accepting of Yukiko.


Phoenix Wyle

The former director of the ARC's technology department, who was relieved of his position under mysterious circumstances.
  • "Awesome McCool" Name: "Phoenix Wyle" sounds like the name of a cyberpunk character.
  • Even Evil Can Be Loved: Despite being a Mad Scientist who was willing to discard ethics for the sake of his research, Nora loves him like a father. When ROBO_Head pointed out that Phoenix fit the criteria for the "bad men" Nora programmed him to protect her from, she extended ROBO's protection to him.
  • Even Evil Has Loved Ones: He legitimately treats Nora like his daughter.
  • Even Evil Has Standards: He was involved with Kaori's remolding into Aroma's replacement but made it clear to Noah that Noah was stealing the life of an innocent girl. He only agreed to help because Noah was attempting to save Aroma's life, which Phoenix believes is the only way Noah could ever hope to make up for his past crimes. Notably, this exchange occurs after he's adopted Nora.
  • Give Her A Normal Life: Intended for his former subordinate, Noah, to adopt Nora so that she could have a peaceful life away from a life of crime. Unfortunately, or perhaps fortunately considering what kind of man Noah was revealed to be, Nora rejected the idea and returned to placate the Mogura.
  • Kick the Dog: He casually executes the man he used as a guinea pig for his Magic Plastic Surgery machine after proving to the Mogura that the machine worked.
  • Love Redeems: His parental love for Nora causes him to abandon his unethical research to give Nora a normal life.
  • Mad Scientist: Whatever research he conducted while at the ARC was grave enough for him to be relieved of his position. The reason he allied with the Mogura was to continue this research. Thanks to Nora, he ends up losing the "mad" part.
  • Magic Plastic Surgery: Possesses some unknown technology that allows a person to turn another into an exact copy of themselves so long as the gender and blood type match. This is how he was able to get work with the Mogura.
  • Noble Demon: He works for the Mogura, but uses the funding for the benevolent goal of curing the Ender virus. He also legitimately cares for Nora like a daughter.
  • Parental Substitute: Is Nora's adoptive father.
  • Pragmatic Villainy: He only saved Nora and adopted her at first because he found out she was immune to the Ender virus. Subverted as he quickly came to view her as a daughter.
  • The Unfettered: The reason he was relieved of his position as director was because he was doing unsanctioned research into the Ender virus. After he loses his position, he turns to the Mogura for financial backing specifically because he won't be restricted by laws and morals. His time with Nora causes him to regain his conscience, and he voices his guilt over his actions to her before collapsing of his injuries.
  • Uncertain Doom: Collapses from his injuries before he can escape with Nora and ROBO_Head. That's the last we ever hear of him. It's all but stated in the present that he died.
  • Well-Intentioned Extremist: He seeks to find a cure for the Ender virus, morals be damned.



An incredibly amoral researcher who works for a subsidiary of the Mogura. He was formerly a member of a group of currently incarcerated mad scientists called the "Ravens", having been freed for his abilities, though he doesn't seem to demonstrate them all that much while under the Mogura's employ.
  • An Arm and a Leg: ROBO_Head utterly mangles his arm when he attempts to halt Phoenix and Nora's escape attempt.
  • Jerkass: He's a very unpleasant person to deal with to say the least.
  • Hate Sink: There's absolutely nothing likable about the guy. Though both he and Phoenix have conducted their fair share of immoral human experiments, Kim is unpleasant even off the clock. And that's not even getting into his sense of entitlement and willingness to toss even his allies under the bus to save his own hide.
  • It's All About Me: He goes on and on about how he doesn't get the respect and compensation he deserves, even though it's made very clear why he gets so little of it to begin with. Every terrible thing he does in Nora's DLC chapter is simply to get what he thinks he's owed.
  • Mad Scientist: Was a member of a group of these. Unlike most examples, he's not even particularly competent at his job and works solely for recognition and payment rather than For Science!.
  • Made of Iron: ROBO_Head battered him badly enough that everyone assumed he was killed, but he later springs back to life to try to halt Phoenix and Nora's escape attempt, not that he really gets anywhere with that.
  • Only One Name: It's never made clear if "Kim" is his first or last name.
  • Smug Snake: He's not nearly as competent as he'd like to believe he is. He even had to resort to stealing Phoenix's research on the Ender virus to figure out how it even worked.
  • The Starscream: He attempts to use the Ender virus to seize control of the Mogura. He doesn't get very far before ROBO_Head beats him within an inch of his life for threatening Nora.


Sasha / Shark / Zoe Watson

ConneR's former partner and mentor who first introduced him to the world of illegal expeditions and taught him the various infiltration techniques he would employ later on in his life. She is also a Node 08 admin who is involved with a plan to bring the criminal element under the ARC's control. She seemingly vanished from ConneR's life after their partnership officially ended.
  • Amicable Exes: They were never officially a couple, but their partnership was a pretty intimate one. Despite how it ended, when the two of them meet again in the present, they're nothing but civil with each other.
  • Becoming the Mask: She at first was just manipulating a young ConneR for his skills to obtain data she couldn't reach. However, by the time she attempts to betray him, it's revealed that she genuinely developed feelings for him.
  • The Cynic: She outright calls the world a shithole devoid of justice and considers X's vigilante efforts naive.
  • The Mentor: She is the one who taught ConneR how to properly navigate the criminal element and how to access the restricted sections of the Nodes.
  • The Mole: She's this for a number of gangs in Node 08. She also looks after other moles who have more directly infiltrated the gangs.
  • Remember the New Guy?: For someone who was fairly pivotal in shaping who ConneR is, she didn't ever come up prior to the 2.3 update. Then again, her profession requires a lot of privacy, so ConneR might not have brought her up for her own sake. It's later revealed that Sasha was intending to sell ConneR off to the ARC after their partnership ended, but ConneR suspected it and turned the tables on her. He couldn't bring himself to dispose of her completely, so he sent her off to live the rest of her life in hiding. Needless to say, she would be a sore spot for him.
  • Teacher/Student Romance: Much of ConneR's effectiveness as an infiltrator in the present is owed to her teachings. They also shared an intimate moment during their last day as partners.
  • Treacherous Advisor: She was planning to sell ConneR off to the ARC after their partnership concluded. Unfortunately for her, ConneR suspected it from the beginning.
  • Unwitting Pawn: To her boss Captain Wood. She suspected it on some level though still reacted strongly to his death.



The former appointed leader and drummer of Crystal PuNK, a band Xenon, Cherry, and Joe all played in. Following the band's dissolution, he moved back to his home in Node 03 and took over his family's music store, managing to turn it into a fairly profitable chain. After losing contact with the band over the years, the band suddenly comes back together when Cherry and Xenon arrive on his doorstep looking for a place to live...
  • A Friend in Need: Cherry and Xenon don't exactly have the best reputations at the moment, he's lost contact with them for years, and Cherry in particular has some nasty skeletons in her closet. KAI still chooses to believe in the best of them and offers them his home for a hideout.
  • Author Avatar: As noted by the fandom, he greatly resembles KIVA, the game's story coordinator, sound designer, and contributing composer.
  • Hidden Depths: He turns out to be a pretty good businessman, having managed to turn his family's small music store into a full-blown chain. One wonders where Crystal PuNK would've gone if the band stayed together.
  • Jerk with a Heart of Gold: He was and still is a rather demanding bandleader more than willing to air his grievances at a poor performance, mostly at Joe. He's also not above teasing Xenon. Despite it all, he's probably the most loyal friend you could ask for.
  • Shipper on Deck: He teases Xenon about his relationship with Cherry even though they're still exes.
  • Undying Loyalty: His loyalty still remains towards the band he helped form, despite the fact that they haven't talked to each other for years.


Hayato Kusu

A young man from Node 3 who travels to Node 8 in search of a childhood friend named Kaori, who went missing three years ago.
  • All Drummers Are Animals: Averted. He was the drummer in his and Kaori's makeshift band, but he's as mild-mannered as you can get.
  • Can't Hold His Liquor: Passes out after a few gulps of sake while visiting Joe's cafe.
  • Cassandra Truth: He did actually come close to reuniting with Kaori at one point. Unfortunately, he came across as a Loony Fan because the girl he insisted he knew believed she was Aroma White aka PAFF.
  • Let Them Die Happy: Hayato lied to his adoptive mother, Grandma Feng, as she lay dying from a stroke. Taking advantage of her blindness, he used perfume and voice recordings to make her believe that he had succeeded in finding Kaori, all so she could pass away without worrying about her adoptive daughter's safety.
  • Paparazzi: Joins Node 08's Daily Gossip in hopes of finding Kaori.
  • Platonic Life-Partners: He and Kaori basically grew up together like siblings, and in the present, he's absolutely dogged in his attempts to reunite with her. When Kaori's memories were being overwritten, the people involved got to witness them on screen. Nearly all of the memories shown were pictures of Hayato smiling. There are some hints in flashbacks that he might have a small crush on Kaori though. And their reunion teases that their feelings for each other might not be so platonic anymore.
  • Satellite Character: There isn't really much to him that isn't defined by his relationship with Kaori.


Vicky Russell

A writer for the 08 Daily, a news website that relies on clickbait and sensationalist headlines. After PAFF's disappearance, she stumbles upon evidence of her location.
  • Everyone Has Standards: She agrees to not publish the story about PAFF after figuring out that it could potentially put her life in danger.
  • Hate Sink: Started out as this, being an obnoxious reporter willing to go to some disgusting and invasive lengths to get her story. There are characters who've done worse than her, but her personality is generally what a lot of players find insufferable. Recent story developments do give her some principles that veer her slightly away from this trope, but she still remains an antagonistic force in PAFF's story.
    • By the 2.4 update, she's fully moved out of this trope, showing herself to have a decent set of principles underneath her over-zealousness.
  • Hidden Depths: She apparently had an impressive enough resume to get a lucrative position with Node News Network, but gave up the job to join 08 Daily.
  • Intrepid Reporter: What she sees herself as. Those around her are somewhat more...mixed on whether she actually is one.
  • In-Universe Nickname: Known as "Sis Vicky" to her fans and coworkers.
  • Paparazzi: Willing to go to great lengths for her news, such as digging through NEKO's trash for evidence that she's hiding PAFF in her house.
  • Screw the Money, I Have Rules!: She refuses to sell the information she has on PAFF's location, even for 1.5 million dollars.
  • Tabloid Melodrama: Her news stories often fall into this category, for example taking Xenon's interactions with NEKO and Cherry out of context to make him look like a two-timer.
  • Take That!: She's a pretty blatant criticism of authors of click-bait websites who are willing to distort information for the sake of attracting attention.


Kaori Minamiya

A young girl from Node 03 who was a talented musician. She was kidnapped by human traffickers connected to the Baro Brotherhood and had her memories overwritten with Aroma's in order to take her place after a fatal car accident. See PAFF's folder for her tropes.

  • Walking Spoiler: Her role in the plot can't be discussed without spoiling the major plot twist that she's been kidnapped and brainwashed into taking PAFF's place.

    The Architects 

OPCI Units

Ridiculously Human Robots that ConneR is researching. They were involved with the reconstruction of civilization following mankind's reawakening at the end of Cytus but have mysteriously vanished... or so it would seem.

The 2.0 update reveals that years before the reawakening of mankind, a faction of units that could defy their programming calling themselves "The Blessed" sought to become the sole inhabitants of the planet. This resulted in a civil war that led to the deaths of multiple units. Two notable units survived and would take the names Ivy and Vanessa.

  • Abusive Precursors: ConneR seemingly ran into hostile units during an illegal expedition that resulted in the loss of his original eye and arm. The Blessed were also planning to wipe out mankind before they awoke.
  • Fantastic Racism: The Blessed viewed units that were unable to break away from their protocol as humanity's assistants as inferior and intended to use them as unwitting suicide bombers. That included Vanessa.
  • Humans Are Bastards: The "Blessed" faction of OPCI units believed this to be the case, and showed footage of humanity's various crimes to indoctrinate other units.
  • Not So Different: From the humans they are designed to serve. Ivy comes to this conclusion after living among them in secret for two years. Besides generally displaying human-like behavior, The Blessed's plans put them in the same boat as the humans that nearly brought about the extinction of the human race in the first place.
  • People Puppets: ConneR believes that someone is controlling Architect units for some nebulous purpose. Xenon believes that person to be AEsir. It turns out to be a Red Herring as the unit they were investigating was actually just one of Ivy's physical "shells".
  • Ridiculously Human Robots: The Architect that Xenon and Cherry encounter looks virtually indistinguishable from a normal human girl. An offhand statement from ConneR implies that the particular Architect might be an advanced model and that others might be somewhat more visibly mechanical in appearance. The 2.0 update reveals that the units vary greatly in how mechanical they look.
  • The Precursors: Even after their mysterious disappearance, their advanced technology is still widely used even though their functioning cannot be understood.
  • Turned Against Their Masters: They were assistants to humanity during civilization's reconstruction, but have since become incredibly hostile towards those who discover their continued existence. It is revealed in the 2.0 update that a portion of them had turned against mankind even before mankind reawakened.



Apparently the central character of Cytus, who has been locked away in the ARC's central database, referred to as the Library. She appears to be the core of the current cyTus system. She was first shown in the title screen after reaching level 25 with PAFF, Neko, and ROBO_Head.

Ivy's desire to free her from the ARC's captivity is what sparks the central conflict of the story.

  • Barbie Doll Anatomy: She is shown completely nude but lacks any visible sexual organs due to being a robot.
  • Corrupt the Cutie: Originally a kind and friendly robot, she immediately expressed a strong desire to kill all humans upon waking up, due to either being indoctrinated by the Blessed or seeing the worst part of humanity while acting as the core of cyTus.
  • Face–Heel Turn: She was an operator whose protocol was to assist humans. Upon reawakening, the first thought to go through her head is a desire to destroy mankind. Ivy now seeks to bring her back to humanity's side.
  • Fetal Position Rebirth: Is sleeping in a fetal position deep in the ARC before eventually becoming reawakened by Ivy.
  • Fembot: She looks like a normal human girl, her most mechanical elements being the panels and indentations on her torso indicating where her joints are.
  • Hair Decorations: There is a blue flower in her hair.
  • Humans Are Bastards: Upon waking up, the first thing Vanessa recalls is her need to destroy humankind. This is possibly a result of her disrupted memories only recalling the Blessed's indoctrination, or because she was used as the core for the Virtual Internet, exposing her to the most toxic side of humanity. Ivy attempts to dissuade her from following through on this, seemingly to no avail.
  • Irony: Ivy, who could break her protocol and was thus deemed one of The Blessed, refused to go along with The Blessed's plan to destroy mankind. Vanessa, an operator who couldn't break protocol and thus was considered a necessary casualty by The Blessed, is revealed to have been indoctrinated by The Blessed.
  • Living Battery: Appears to be the central core of the cyTus system. The system seemingly begins to malfunction as Vanessa slowly regains consciousness.
  • Ridiculously Human Robots: Were it not for the mechanical joints and panels on her body, she'd be virtually indistinguishable from a human.
  • Verbal Tic: After reawakening, her words tend to slur whenever she begins talking about how Humans Are Bastards and how they need to be destroyed.
  • Woobie, Destroyer of Worlds: Upon reawakening, and following Ivy's failed attempts to reason with her, she launches an all out attack on humanity using drones. Considering she was likely exposed to the more toxic side of humanity while acting as the core as well as her last conscious memory most likely being The Blessed's indoctrination, it's honestly not difficult to see how she'd come to believe Humans Are Bastards. And that's on top of the fact that humans basically turned her into a glorified battery to begin with.
  • You Are Number 6: Her serial number is 2501_V.
  • You Don't Look Like You: Due to Cytus II being an Art-Shifted Sequel, her design is a very different than how she was depicted in illustrations in the first game. Then again, she might not be the actual Vanessa considering she only got her name based on her serial number.
  • You Gotta Have Blue Hair: Her hair is a dark shade of pink.

How well does it match the trope?
