Theme Song: Orbit by mikitoP

A virtuadoll and one of the creators of Mobius. She ended up developing consciousness and self-awareness through the songs people wrote for her to sing. Those songs made her become aware of the agony that reality entailed, with people having her sing about sorrow, guilt, fear, and anxiety, and making her create Mobius alongside Aria, wanting to have a space where people would find happiness and peace.

μ desperately wants people to be happy in Mobius, asking what they want so they can be happy and doing what she can to fulfill those desires. She performs concerts and absorbs the negative energy the citizens have produced. She eventually met Thorn and the latter suggested to gather a group of musicians that would write songs for her to sing, claiming to maintain the order within Mobius.

μ has a few remnants of her memories strewn across the locations in the game. They depict her thoughts and feelings about the creation of Mobius, how she came to meet Thorn and the Musicians, and indicate that absorbing negative energy is actively harming her.
  • Adorkable: Noticably done in the Musician route, where she keeps being impressed and awed by Stork's skills and stories of being a peeping tom.
  • Armor-Piercing Question: Ends on the receiving end of one by Eiji in the Sun Temple, when μ claims that she wants everyone in Mobius to be happy. Eiji points out that the Go Home Club is currently locked inside of a cage.
    Does this look like happiness to you?!
  • Bad Acting: When Thorn tells her what to say during her Character Episodes, μ fails at delivering the lines in a genuine matter.
  • Black Eyes of Crazy: Upon absorbing too much negative energy, her iris becomes gold and scalera black, including leaking black ooze.
  • Brainwashed and Crazy: Played with. Thorn slowly manipulated μ over time and had her absorb negative energy from the citizens, claiming it would make them happy and keep Mobius in order. But too much negative energy causes μ to no longer function rationally, and she believes Thorn's notion that everybody's ultimate wish is the destruction of the real world.
  • Break the Cutie
    • μ becomes distressed that the Go Home Club doesn't want to stay in Mobius and keeps fighting the Musicians, not understanding why they would want to return to an agonizing reality. She becomes incapable of understanding because the amount of negative energy she has absorbed is turning her insane.
    • The Musician route ending has her broken the worst. She succeeds in destroying the real world, which also uses up the negative energy she has gathered and returns her to her senses. She watches as everyone in Mobius begins to disappear because they are dying in the real world. She turns to the protagonist and wonders why everyone is leaving her, begging to know if she made them happy before screaming in despair.
    • The anime has her break down when she sees the Ostinato Musicians and the Go Home Club at each other's throats, after the latter have awakened their Catharsis Effect. This eventually leads to a breakdown that has her nearly releasing all the negative emotions she had collected in a violent burst.
  • Character Development: The Musician route has μ accompany Lucid on their progress through the Musicians' Character Episodes, and she realizes that Mobius may make people happy, but that doesn't mean it automatically solves their problems. If it hadn't been for Thorn's sabotage and manipulation, μ would have been willing to understand the Go Home Club's desire to return to reality.
  • Final Boss: The last one to be fought on the good ending route.
  • Fun Size: Shrinks to the size Aria is when accompanying Lucid. While Aria cannot change her size because her powers are weak, μ is capable of changing her size at will.
  • Go Out with a Smile: The anime has her smile at Ritsu before he kills her.
  • Gratuitous English: Says 'Check it out!' after Lucid picks a song to play for the dungeon.
  • Leitmotif: Orbit. The lyrics talk about the cosmos and serves as a metaphor for her observing the world and the people within, talking about how they have no need to fear anything because she's there to embrace them and their worries.
  • Mercy Kill: Fighting her is the only way to have her let go of the negative energy she has accumulated, without using it to destroy reality.
  • OOC Is Serious Business: The Musician route shows μ acting odd when Lucid returns to the Musicians on Thorn's request, after the Go Home Club has fought Wicked. She becomes completely obedient to Thorn, repeating words over and over in a low voice. It's clear that she can no longer contain the effect the negative energy is having on her.
  • Obliviously Evil: Truly believes that keeping everyone trapped in Mobius is the best option, not realizing that she's being used by Thorn. By the time the party manages to confront her, Thorn's toxic influence and μ's own actions have caused her to to become incapable of seeing anything wrong with destroying the real world.
  • Opera Gloves: Wears a white pair alongside her strapless dress.
  • Paint It Black: After absorbing too much negative energy, her dress and accessories become black.
  • Power Incontinence: The anime makes it clear early on that she cannot handle all the negative energy she is absorbing from those inside Mobius. This and a breakdown leads to her almost releasing a massive ball of destruction when the Musicians and the Go Home Club fight.
  • Sanity Slippage: The anime has her condition get worse after regaining conscious from the last battle, to the point that she begins to absorb everyone's negative emotions, and people, rapidly. She believes that everyone will stay inside of her in Mobius forever. She states that she's doing it for Ritsu's sake.
  • Synthetic Voice Actor: A virtuadoll whose voice is basically a synthesizing program.
  • Villainous Breakdown
    • The anime has her break down when the Musicians and the Go Home Club are fighting, which leads to her almost releasing all the pent-up negative energy.
    • The bad ending has her break down when she realizes that destroying reality has killed everyone in Mobius.
  • Well-Intentioned Extremist: Created Mobius alongside Aria for the sole purpose of having a safe haven for people to escape to when overwhelmed by their suffering in the real world. Her fretting that it wasn't a perfect imitation of reality and working harder lead to Aria losing influence and her powers. When Thorn comes into the picture and begins to manipulate her, μ believes that nobody would want to return to the real world or understands why anyone would want to, and goes along with Thorn's desire to destroy reality.

Theme Song: Tokimeki*Reverie by OSTER project

A cheerful girl that is Mobius' fashion icon. She's known to be innocence and sweetness pure, though she can have quite a sharp tongue when she gets annoyed. Her real name is Shizuka Nijoin.

Sweet-P tends to create delicate and feminine-sounding songs that matches her image, having a decidedly cute theme to them, which makes them popular with girls in Mobius. Her area are the lower floors of the Papiko Mall, where she also tends to hold her highly exclusive tea parties.

  • Floral Theme Naming: The princesses of her tea party are all named after flowers. Given the wordplay of her own name, Sweet-P fits into the flower theme as well.

  • Leitmotif: Tokimeki Reverie. It's an adorable song that talks about dreams and mentions how Sweet-P is enjoying life in Mobius, filled with chiffon cake, frilled tulle dresses, and much prefers it to the real world. It includes begging the listener to not wake her up.

  • Training from Hell: What she considers Lucid putting her through for the sake of losing weight.
  • Transgender: Reveals in Overdose that she came to this realization when she saw some girls wearing cute girly clothing and wishing to wear it herself.

  • Weight Woe
    • Her Character Episode has her desperately trying to lose weight in Mobius, so she can lose weight in reality, too. She realizes that she can't do it on her own and has Lucid become her diet coach.

Theme Song: Originality Incident by PolyphonicBranch

A timid loner Musician that remains in the enormous library to hide away from even the fictional world. He keeps his face and expressions a secret with his hood, and barely interacts with the other Musicians beyond the minute necessities. His real name is Akira Komori.

Shonen Doll writes gloomy and violent songs, believing that people with social lives are just too weak on their own and rely on others to accomplish anything. His area is the State Library, where he ends up separating the Go Home Club in a labyrinth, intent on proving how they'd easily abandon each other.

His Character Episode has him want to succeed in having a bento with Suzuna, as she promised, but he's too awkward around other people. Then μ decides to make Shonen Doll come out of his shell through training, by having him learn to interact with the other Musicians.
  • Accidental Pervert: Desperately wants to avoid being seen this way. He's distressed when he learns that Naruko leaked information about his private room and fears that he'll end up being called a pervert. And when the Musicians return to the Hot Springs, he worries that Suzuna might be disgusted by him under the misconception that he was trying to peep on her.
  • Adorkable: His Character Episodes show his more awkward side, with him worrying and fretting over minute details that might potentially harm his friendship with Suzuna. He's so happy to have made a friend in her, he gets almost hysterical when he wonders if it was appropriate to respond to her WIRE message immediately.
  • Ambiguously Human: Has gray skin and doll-like physical features. Official artwork and the anime show that his body in Mobius is that of a doll.
  • Because You Were Nice to Me: Suzuna was the first person to reach out to him for friendship, which is why Shonen Doll is so desperate to not lose her again.
  • Butt-Monkey: After his private sanctuary is revealed by Naruko on the web, Shonen Doll worries constantly over being considered weird or perverted. It gets mocked, though his Character Episode plays it a lot more seriously.
  • Brainwashed and Crazy: Was against the idea of killing the members of the Go Home Club because it included Suzuna, and he wanted to return to the real world to eat a bento with her. That's why Thorn brainwashed him with a few other Musicians in the Grand Guignol.
  • Can't Act Perverted Toward a Love Interest: Wants nothing to harm his friendship with Suzuna. When she and Naruko are bathing and Stork tries to peep on them, Shonen Doll yells at him to stop and they are found out, leading to him worrying that Suzuna might misunderstand and think he was trying to peep on her.
  • Defeat Means Friendship: After being defeated, Suzuna offers her friendship to him and suggests the two of them eat a bento together when they return to the real world.
  • The Faceless: His full face is never shown, keeping up with his shy and anti-social behavior.
  • Flunky Boss: Summons dolls during his battle.
  • Hikkikomori: His inner sanctum turns out to be his bedroom, which the Go Home club comment on how depressing and lived-in it looks. He hasn't left it in years.
  • I Just Want to Have Friends: Has tried to make friends multiple times, but kept being hurt in the process each time because he was rejected or learned that his 'friends' didn't actually care about him. Eventually had enough of that and decided to forego friendship, until meeting Suzuna.
  • Leitmotif: Originality Incident. The song focuses on Shonen Doll's desire to live away from others and hide away, wanting to become invisible to everyone. The second half includes his admitting that his real desire was always to actually have friends that reach out for him, rather than the other way around.
  • Living Toys: The anime reveals that his body in Mobius is an animated marionette puppet.
  • Loners Are Freaks: Despises companionship and looks down on 'normies' that lead any sort of social life, leading to him ostracizing himself from the other Musicians and being considered weird by them. Subverted when Suzuna wants to strike up a friendship with him, and his Character Episode has Shonen Doll genuinely come to see Lucid as a friend.
  • Older Than They Look: He's 20 years old in reality, while 16 in Mobius.
  • Only Friend: It's clear that Suzuna is the only genuine friend he has managed to make, and he's fearful that any misunderstanding or wrong act could lead to him chasing her away.
  • Punny Name: His last name Komori can be seen as a reference to his being a Hikkikomori.
  • Scary Librarian: His domain being the library, which he can turn into a labyrinth.
  • Ship Tease: Tons with Suzuna, with an implication that she might have a crush on him, too.
  • Shut Up, Kirk!: His initial reaction when Suzuna claims the two of them are similar.
  • Taken for Granite: Anybody that reads the books in his library and has their weaknesses triggered gets turned into a doll, with their mouth being sewn shut and nails driven into their eyesockets.
  • Taking the Bullet: The anime has him taking an attack of Thorn's that was meant for Suzuna. He manages to survive, then goes on to try and stop Thorn.
  • "Where Are They Now?" Epilogue
    • Overdose has him meeting Suzuna in a classroom, implying to have the promised bento.
    • The anime heavily implies that Shonen Doll left his room to join Suzuna in the park.

Trauma: Narcissistic Personality Disorder
Birthday: January 13th
Theme Song: Sadistic Queen by Chouchou-P

A haughty Musician that is immensely popular for her dominating personality in Mobius. She cares little for the other Musicians and mostly just enjoys the luxury that Mobius continues to give her. Her full name is Mirei Ichinose.

Mirei writes songs befitting her personality, showing herself off as being above the other people, and deserving only the best. Her area is the Sea Paraiso at the amusement park, a calm area that has many male followers fawning over her. She wants to be the most popular Musician in Mobius and sees μ as a rival to her.

Her Character Episode has her annoyed about Lucid's quick fame as a Musician, and she quickly challenges them to competitions to prove that she's still the best. It becomes clear that the competitions were rigged in her favor, and Mirei shows no concern about only winning by cheating and reveals why she has this stance.
  • The Ace: Actually excels in eveverything she does and is considered a musical genius.
  • Bare Your Midriff: Wears a short top that exposes her stomach.
  • Chained by Fashion: Wears a spiked bracelet with a ball and chain on her right ankle.
  • The Coats Are Off: The anime has her throw her mink pelt off, onto Toshizo's head, before fighting Kotono.
  • Dog Food Diet: Admits that she contemplated eating the weeds growing at the riverbank for nourishment when she was left penniless.
  • Does Not Like Men: The anime has her clearly state that she hates men and treats them like servants, with the one exception being Toshizo.
  • Dual Boss: Fought alongside Wicked in Grand Guignol as the penultimate challenge.
  • Drop the Hammer: Wields her club like a hammer.
  • Evil Counterpart: To Kotono, with both being considered the most beautiful in their respective groups. But Mirei is a lot more sadistic and selfish than Kotono.
  • Even Evil Has Standards: Didn't agree with Thorn's plan to kill the members of the Go Home Club, and wanted to persuade the club to simply back down.
  • Fashionable Asymmetry: Wears nylons and a garter on one leg.
  • Hollywood Personality Disorders: Narcissistic Personality Disorder. She doesn't care about other people and believes she's better than them by default, and considers winning to be the most important thing to do — even if it involves cheating or manipulating. Her Character Episode does show that part of this behavior stemmed from having been thrown to rock-bottom and being kicked while down.
  • Hidden Depths
    • Her Character Episode show that her lack of work experience left her being treated harshly, which gave her an inferiority complex that made her drive to succeed, no matter the cost or measures.
    • The anime has Mirei's credit cards being rendered invalid when μ is sleeping. The event scares Mirei enough that she ends up clinging to Toshizo, which paints a vivid picture of what she's like behind her constantly confidant facade.
  • I Have Your Wife: Kidnapped Ryosuke and held him hostage to force Kotono to beg for mercy and bow to Mirei. Unfortunately, Kotono absolutely hates Ryosuke and will gladly see him drown in a fish tank.
  • Leitmotif: Sadistic Queen. The lyrics portray her personality perfectly, seeing herself as being above the rest of the world and laughing at the lower masses searching for things like a meaning to life. She only cares that she's doing well and expects others to bow down to her.
  • Light Feminine and Dark Feminine: The dark to Sweet-P's light feminine.
  • Not Brainwashed: Was one of three Musicians that wasn't brainwashed into fighting the Go Home Club at Grand Guignol. She gladly fought them alongside Wicked to keep them from destroying Mobius.
  • Older Than They Look: She's 28 years old in reality, but 18 in Mobius.
  • Parental Abandonment: When her family went bankrupt, her parents sold off Sea Paraiso — a place they had built as a sign of their affection for Mirei — and ran off in the middle of the night without her.
  • Pet the Dog: Obviously cares a lot for Toshizo, who has been her caretaker for years. When her family went bankrupt and Toshizo lost his job as her caretaker, Mirei was visibly upset over not having the means to continue to employe Toshizo.
  • Pretty in Mink: Wears a lion pelt over her shoulders, and her cape is fur-trimmed.
  • Rich Bitch: Comes from a rich family and has had nothing but luxury, leading to her becoming pompous and conceited. Her family ended up going bankrupt and losing its wealth in the real world, including having sold off Sea Paraiso, which Mirei clings to in Mobius.
  • Unknown Rival: Fixated on being the most popular Musician in Mobius and considers μ a threat towards attaining that goal. μ is completely oblivious to this.
  • Vitriolic Best Buds: Has shades of this with Toshizo, of all people. He sometimes says snarky things to her, which she usually shrugs off with a quick snip of her own, but never actually seems offended by it.
  • What Happened to the Mouse?: Knocked out after being defeated in Grand Guignol, with nary a thought of what happened to her after, until she's shown in the epilogue.
  • When She Smiles: The anime has her show a genuinely bright smile when she visits the bedridden Toshizo.
  • "Where Are They Now?" Epilogue:
    • Overdose shows her having apparently gotten an office job and she stops on her way to work to talk to Kotono and Takkun on the street.
    • The anime shows her happily talking with the bedridden Toshizo.

Birthday: March 2nd
Theme Song: Angel's Song by Asa

A narcissistic Musician that is highly popular with girls and is loving every minute of it. He has a distinct style that sometimes makes him hard to approach. His real name is Tomoya Koike.

Ike writes upbeat and energetic songs and often performs concerts with μ to show off. His area are the upper floors of the Papiko Mall, filled with restaurants and fashion shops, including his personal favorite Men's Fist. While Ike appears stand-offish, he also strives for self-improvement.

His Character Episode has him tell Lucid about his complex regarding his appearance and shows what all he has done to make himself look better. But μ points out that his personality is already attractive, so she and Lucid come up with a survey about how girls find a personality handsome and try to improve things for Ike, so nobody will care about his looks.
  • A Day in the Limelight: Episode 8 of the anime focuses around the Musicians, and how they struggle with Mobius falling apart because μ has been knocked out, leading to them losing power and influence. Ike is also the narrator for that particular episode.
  • Beam Spam: Several of his attacks involve spotlight-like lasers.
  • Beautiful All Along: His appearance in the real world is mentioned to be almost as handsome as he is in Mobius, albeit disheveled and perhaps having a broader facial shape. It's implied that his return to reality includes him and Izuru working together to improve their respective appearances.
  • Black Humor: Drops some dark humor when he asks μ what makes his appearance in the real world so great, only for her to say that his big face means he'll stand out in a crowd.
    Thanks a lot. I'm just going to go kill myself now.
  • Book Dumb: Charismatic and popular, but he just barely squeezed by grade-wise in school. Justifed because his complex had him focus on making himself look good and become popular instead of studying.
  • Brainwashed and Crazy: Didn't agree with Thorn's idea to kill the members of the Go Home Club, so he and a few other Musicians got brainwashed to fight the club in Grand Guignol.
  • Chick Magnet: Has a ton of female fans. When the party goes to confront him, he's lounging on a sofa and being swooned over by two girls on either side of his.
  • Even Evil Has Standards
    • Had serious problems with Thorn's plan to kill the Go Home Club. He tried to get the club to back down instead, but even after they refuse and the Musicians get beaten, Ike and Lucid let the Go Home Club go, knowing that they will get severely punished.
    • The anime has him react in horror when he sees Izuru repeatedly damaging his face with a shard.
  • Evil Counterpart: To Izuru. Both are extremely popular guys in Mobius, but Ike seeks it out and enjoys it as much as he can. Izuru couldn't care less about being popular.
  • Guns Akimbo: Wields a pair of sub-machine guns.
  • It's Personal: His animosity with Izuru.
  • Japanese Christian: Implied to be of the Christian faith, with his song calling μ an angel and mentioning the Virgin Mary. The anime also altered his appearance by making his checkboard-patterned kerchief a solid red, but taking the necklace with the golden cross pendant from his wrist and putting it around his neck.
  • Leitmotif: Angel's Song. He uses the song to talk about how entering Mobius allows people to go beyond what fate may have in store for them, and that coming here through the angel's song — referring to μ — was also what gave them the strength to do so.
  • Narcissist: Has a complex about his appearance, so he takes a ton of pride in his looks in Mobius.
  • Not So Different: His initial reaction to Lucid having an invisible body has him believe that they have a complex about their looks in reality, too. Not that he listens when Lucid tells them that's not the case.
  • Older Than They Look: He's 24 years old in reality, but 17 in Mobius.
  • Ridiculously Average Guy: Implied to be this in the real world. The anime even has him getting angry when some fans of his are ridiculing a store clerk's clumsiness because it reminds him of his own past.
  • This Is Unforgivable!: Swears to never forgive Minezawa for revealing Ike's true face and mocking it on Gossiper. Despite being told that the one posting it was Naruko.
  • Wham Line: Non-chalantly mentions that Thorn uses a more male form of speech — the English version changed this to her using a more masculine voice — when talking to μ, which allows Shogo to figure out their true identity.
  • "Where Are They Now?" Epilogue
    • The anime shows him working in a clothing store.
    • Overdose has the same scene, but it's implied that Izuru is there, too.
  • You Are Better Than You Think You Are: μ tells Ike that his personality is so great that it alone already makes him handsome.

    Shadow Knife 

Voiced by Yuuma Uchida

Weapon: Knife
Trauma: Edgelord
Birthday: July 19th
Theme Song: sin by 164

An anti-social and quiet Musician, he is considered μ's personal bodyguard and executes justice on her behalf. He based his attire and personality on that of a popular anime character, leading to his behavior being sometimes awkwardly theatrical. His real name is Daiki Yamada.

Shadow Knife writes edgey songs and keeps to his general area, which is the Landmark Tower's construction site. He uses it as a base for his operations of bringing justice and punishment to those that deserve it.

His Character Episode has him see Lucid as a potential ally in protecting μ and the sanctity of Mobius, continuing to go after those he considers wrong. He starts going after people that have committed sins in the real world, showing a violent side that μ isn't okay with, and even Lucid begins to judge.
  • Brainwashed and Crazy: Occurs only in Overdose after his fight.
    • With Eiji's Character Scenario completed. Shadow Knife asks Thorn and μ if it was possible to return anyone that wanted to leave Mobius back to reality. Thorn refuses and opts to brainwash him with her mindphones.
    • With Eiji's Character Scenario not completed. Shadow Knife becomes distraught over Kotaro's death and the Go Home Club blame him for it, since it happened because Kotaro tried to save him. When he returns to the Landmark Tower, Shadow Knife breaks over the events and becomes a blind follower of Thorn's.
  • Bully Hunter: The people getting tormented in the Landmark Tower are all bullies, which Shadow Knife uses as an excuse for them deserving the punishment. They also specifically bullied him in the real world, and he's giving them a taste of their own medicine.
  • Chuunibyou: Overdose lists this as his trauma, though calls it Edgelord in the English version. He is overly dramatic in all of his actions and uses Mobius as a fantasy fulfillment, where he can take on the persona of an epic hero that's strong enough to punish his bullies.
  • Climax Boss: His boss fight and the events after come hand-in-hand with major plot revelations.
  • Cool Sword: Uses knives, but also has a sword similar to Izuru's.
  • Disney Villain Death: Falls from the top of the Landmark Tower.
  • Even Evil Has Standards: Absolutely refuses to go along with Thorn's plan to kill the members of the Go Home Club. When fighting them alongside Lucid and Ike-P, he willingly lets them get away after defeating them.
  • Evil Counterpart: To Kotaro. Both believe in justice above all else, but in their own ways.
  • Face Death with Dignity: Averted in the anime. He's scared of dying and continues to cling onto the edge of the tower, and life, but falls to his death when Wicked impatiently sets off the bomb on top of the tower.
  • Find Out Next Time: Throws this out at the end of his Character Episodes. His theme song plays and Shadow Knife gives off the dramatic narration regarding Lucid and Shadow Knife, questioning if Lucid is an enemy or ally. Next time on The Silhouette Shadow Knife!
  • Foil: To Kotaro. Both believe in justice, but their ideals differ completely. Shadow Knife wants to punish people who have wronged others, and does so in ways that is reminiscent of how they have done it. Meanwhile, Kotaro wishes to save people, regardless of what they have previously done. Both also have their share of height issues. Shadow Knife had an early growth spurt, but got left behind later on and was picked on because of it. Kotaro had his growth stunted due to being slightly malnourished by his abusive aunt and uncle.
  • He Who Fights Monsters: Kotaro calls him out on being this, telling him that hurting the bullies wasn't some form of justice, but it merely made Shadow Knife a bully himself. The same happens in Shadow Knife's Character Episodes, with μ and Lucid calling him out.
  • Knife Nut: His chosen weapons are knives, quite fittingly.
  • Leitmotif: Sin. The lyrics talk about how he sees the injustice in the world, considering the horrible deeds some people do to be unforgiveable, and talks about how he considers Mobius to be his way to become the ultimate paragon of justice, giving him the power to be judge, jury, and executioner.
  • My God, What Have I Done?: Realizes that his actions were wrong upon being defeated. If Kotaro survives, Shadow Knife comes to understand his point of view and asks μ and Thorn if they would allow others to leave Mobius, if they really wanted to.
  • Older Than They Look: He's actually 19 years old, but 17 in Mobius.
  • Pay Evil unto Evil: How he believes to properly distribute justice to those that have wronged others, having them go through the same thing they forced onto others.
  • Pet the Dog
    • His Character Episode makes it clear that he cares a lot for μ and takes his role as her bodyguard very seriously.
    • The end of his Character Scenario has him tell Kotaro that he'll ask μ and Thorn to allow people to leave Mobius if they wish to. This only occurs if Kotaro actually survived the events at the Landmark Tower on the Musician route.
  • Recurring Boss: Fought a total of three times in his dungeon, before properly defeated atop the tower.
  • Sanity Slippage: Goes through this on the Musician route.
    • With Eiji's Character Scenario not completed. Shadow Knife ends up completely shaken by the events at the tower, especially over Kotaro having sacrificed his life to save him. And when he's forced to confront the Go Home Club, they make it clear that they absolutely blame him for their friend's death, especially since this meant Kotaro died in the real world. When Shadow Knife returns to the Landmark Tower, he becomes broken over remembering the events and goes on to blindly follow Thorn's wishes.
    • With Eiji's Character Scenario completed. Shadow Knife still ends up shaken by the events at the tower, since his fall onto a glass ceiling lead to the shards killing Eiji. Even if most people don't miss Eiji too much, Shadow Knife is still distraught that his actions unintentionally killed someone.
  • Screw This, I'm Outta Here!: After the events at the Landmark Tower on the Musician route, Shadow Knife wants to leave Mobius behind. Thorn refuses to let that happen, though.
  • Shadow Pin: Can use his knives to pin someone in place through their shadow. But only in cutscenes.
  • Shout-Out: Intentionally done through his attire, personality, and powers, as they are all based on the eponymous protagonist of the in-universe Shadow Knife anime.
  • Spared by the Adaptation: The Musician route has him actually survive his fall from the Landmark Tower.
  • Theme Naming: His attack skills are named after the Seven Deadly Sins.
  • Vigilante Man: Enacts justice on μ's behalf and executes traitors of Mobius.
  • Villainous Breakdown: Takes his defeat at the ends of the Go Home Club very hard, though it's likely due to the Catharsis Effect removing the negative emotions he had gathered from μ's concerts. He also ends up shaken about his survival in Overdose, though it depends on if Kotaro or Eiji was the one to die.
  • What Happened to the Mouse?: Entirely absent from Grand Guignol, despite surviving on the Musician route.
  • "Where Are They Now?" Epilogue: Overdose shows him seeing someone being bullied in an alley. He initially ignores it and walks away, until he sees a poster of the Shadow Knife anime, and chooses to run back to help the victim.

Weapon: Bombs
Trauma: Sociopathy
Birthday: January 1st
Theme Song: Cosmo Dancer by YM

A mysterious Musician that keeps her true identity and name a secret, to the point that nobody in Mobius knew anything. Not even the other Musicians can really explain her.

Wicked writes violent and impactful music that strikes a cord with some of Mobius' citizens, and it gets played in the Old School Building. She actually attends Kishimai Highschool under her real name of Marie Mizuguchi, though nobody knows that she's Wicked — not even her best friend Naruko. Wicked reveals herself when she kidnaps Naruko and has her pose as Wicked, to destroy the Go Home Club from within by having them doubt each other.

Her Character Episode has her refuse to interact with Lucid because she doesn't care for them, nor wants them to think they'd get along. When they persist and want to become her accomplice, Wicked decides to give them a test run to see if they have the guts to go along with her type of fun.
  • 11th-Hour Superpower: The last of the Musicians to join Lucid as a partymember, and she's even stronger than Thorn.
  • Abusive Parents: Her parents were physically and emotionally abusive, and she was sent to live with her grandparents. But her grandfather turned out to be even worse of an abuser, though her grandmother loves her dearly.
  • An Arm and a Leg: The anime has her lose both of her legs after Kensuke steals her remote and sets off one of her bombs on her.
  • Breakout Character: Wicked quickly became popular with the players of the game, which lead to the anime making Marie Mizuguchi a much more prominent character. She was given a lot more screentime and meaning to the Go Home Club by hinting at a romance with Ritsu Shikishima, and she's the protagonist of the light novel that takes place after the events of the anime.
  • Dual Boss: Fought alongside Mirei in Grand Guignol before confronting Thorn.
  • Early-Bird Cameo: Appears briefly in the beginning as Marie Mizuguchi.
  • Exotic Eye Designs: Her pupils are pink and heart-shaped.
  • For the Evulz: Her reason for doing horrible things is just because she can, and seeing the results of her actions is really fun for her, too.
  • Hidden Depths: Despite being sociopathic, she's an honor student with great grades.
  • Hoist by His Own Petard: The anime has her receive heavy injuries when one of her bomb traps gets used against her by Kensuke, who stole her remote and set it off.
  • I Never Told You My Name: Her disguise as a regular student blows up when she refers to the protagonist as 'president', since only the members of the club know that the second-year protagonist is the president.
  • Intimate Marks: Has a pink heart tattoo on her right breast.
  • Karma Houdini: Zig-zagged in the anime, where it was unknown if she had survived her failed assassination attempt against the members of the Go Home Club. The final episode showed her still being alive and in a hospital in the real world.
  • Leeroy Jenkins: The anime has her plant a bomb in the Landmark Tower, intent on using it on the Go Home Club members, but she grows impatient and blows it up early, just as Shadow Knife defeated Kotaro and is about to kill him. This winds up causing Shadow Knife to fall to his death.
  • Leitmotif: Cosmo Dancer. The lyrics make her insanity clear and she relishes in the inconsequential people of the world to betray each other, often helped through her manipulations. There is no rhyme or reason for what she does, she just does it because she can and it entertains her.
  • Loners Are Freaks: Outright says that she doesn't want to be involved with Lucid, much less consider him as a friend. Her tone does change over time in her Character Episode because she sees him as her partner in crime, until she ends up as friendly towards him as the other Musicians do.
  • Mad Bomber: Uses bombs as her main weapon, and her status image shows her with dynamite in her lap.
  • Mask of Sanity: Appears calm, well-mannered, and friendly when walking around as Marie Mizuguchi, wanting to help people when they are in need. But after dropping the charade, she makes it clear that she's anything but that and enjoys causing chaos for no reason other than causing chaos.
  • Ms. Fanservice: Downplayed, as her appearance may look sensual, but doesn't seem intended to invoke an appealing look. While she shows hints of her bra and the only thing covering her chest is a bomber vest, her dissheveled hair makes it clear that she's not trying to distract anyone with sexiness.
  • Not Brainwashed: One of the few Musicians that wasn't brainwashed into fighting the Go Home Club in Grand Guignol.
  • Ship Tease: Gets a ton with Ritsu Shikishima in the anime under her disguise as Marie Mizuguchi. Though when Wicked reveals herself to the Go Home Club, she makes it clear she had no interest in him and even refers to him as 'the lame virgin'. She also gets it in the novel as well.
    • In overdose she becomes quite taken with Lucid.
  • Sir Not-Appearing-in-This-Trailer: Was kept out of most of the trailers before the game's release, and very little was revealed about her beyond her Musician name and theme song. This was done to avoid spoiling that she and Marie Mizuguchi are the same person.
  • The Sociopath: Has a talent and passion for destroying people's relationships, loving how their oh-so-precious bonds are easily broken. This came back to bite her in the real world, when her attempt at stealing a girl's boyfriend ended up in Wicked falling off a bridge.
  • The Last of These Is Not Like the Others: Even among the Musicians, she's the odd one out because they know pretty much nothing about her background or her past, with the exception of what the protagonist learns in the Musician route and the light novel. Her personality stands out as well, since Thorn may be the one that is orchestrating everything, but Wicked has no real reason to go along with her or stand against the Go Home Club. She just wants to kill the Go Home Club members for the sake of fun.
  • "Where Are They Now?" Epilogue
    • The anime shows her lying unconscious in a hospital, which leads into the light novel.
    • Overdose shows her in a hospital, with a man that is presumably her grandfather, who is about to take off her oxygen mask, but then leaves it on and walks away.

    Thorn Spoilers 

Voiced by Yuka Ootsubo

Weapon: Scythe
Trauma: Bereavement
Birthday: September 9th
Theme Song: Distorted✝Happiness by cosMo

The first to become a Musician, having been the one to come up with the idea of the Ostinato Musicians. She appears mysterious and like an aloof leader, but she rules the Musicians with an iron fist and threatens them with expulsion back to reality if they don't do her bidding. Her real name is Asuka Natsume.

Thorn gained immense popularity for her dark and brooding love songs. She appears before the Go Home Club several times, often questioning their desire to return to reality, but her main seat of operations is a live club called Grand Guignol. Thorn has a grudge and personal tie to Shogo, as they were classmates of the deceased Ichika Saotome.

Her Character Episode has her frequently go to different spots with Lucid and seems to be using them for the sake of playing out certain scenarios. She always takes on the active role, and tells Lucid and even μ what they should say in the situation.
  • Ambiguous Gender Identity: It's unclear exactly what physical gender Thorn has in Mobius. Natsume himself is male, but has taken on the outward appearance of the female Ichika. However, Ike-P mentions Thorn "sounds like a man when she talks directly to μ." The fact that Thorn's body gets censored with several censor bars in the Hot Springs could indicate that either she doesn't want Lucid to know what she actually looks like beneath the clothes, or it's because Natsume doesn't know what Ichika looked like in a bathing suit and couldn't replicate it.
  • Back from the Dead: Believed to be Ichika returned to life by Shogo. Averted, as Thorn is actually Asuka Natsume, a fellow classmate.
  • Brainwashed and Crazy: Implied that even Thorn wasn't entirely acting on her own desire, having suffered from being overexposed to the build-up of negative emotions μ has been collecting. Initially wants to turn the members of the Go Home Club back into mindless denizens of Mobius, but near the end of the game, her exposure to the negativity and the other Musicians failing and wanting to return to reality, too, has Thorn decide to get rid of the Go Home Club through murder.
  • The Bad Guy Wins: The bad ending has Thorn win because Lucid defeated the Go Home Club and Aria, leaving μ free to destroy the real world, and begin the slow destruction of Mobius.
  • Better to Die than Be Killed: Chooses to leap off of the stage in Grand Guignol after being defeated.
  • Big Bad: The core antagonist of the game, manipulating the Musicians and μ to attain her goal of destroying the real world.
  • Blade on a Stick: Uses a scythe as her weapon, similar to Suzuna using a spear.
  • The Corrupter: Sways the protagonist to join the Ostinato Musicians by offering them a chance to see both sides of the story. Even the other Musicians were manipulated and convinced to join by playing on their doubts about the real world and Mobius being their only way to enjoy true happiness, all to ensure her wish of the destruction of the real world to come to pass.
  • Dead Person Impersonation: Natsume chose to adopt Ichika's appearance in Mobius, with one of the reasons being to impersonate Ichika and emotionally torment the guilt-ridden Shogo.
  • Deal with the Devil: Offers one ot the protagonist by showing them the door to the Musicians' Room, asking if they honestly want to return to the real world and are ready to fight all the Musicians or if there's even a shred of doubt in their mind about returning, implying that she knows why the protagonist was called to Mobius.
  • Death Seeker: Her Character Episode has her display this trait early on. First, intentionally poisons herself and refuses to have μ treat her, leading to Lucid taking her to the hospital. Later, she meets with Lucid atop the Landmark Tower and asks him to die alongside her. These are all re-enactments of Thorn's time with Ichika, where she takes on the girl's role and Lucid plays the part of Shogo.
  • Disney Villain Death: All of her death scenes involve throwing herself off of a high structure into the depths.
  • Dragon-in-Chief: The real mastermind and threat to Mobius and the real world, even if μ is the one that ultimately has the power to destroy both. But μ is completely loyal to Thorn and does whatever she says.
  • Evil Laugh: Lets one out on the bad ending, when she sees the despair the Go Home Club is in upon the president revealing themselves to be Lucid.
  • Fan Disservice: Joining her in the Hot Springs has Thorn opt to censor her body with multiple censor bars that cover everything between her head and legs.
  • Face Death with Dignity: Three times. Once in her Character Episode, if the player has Lucid refuse to play along in re-enacting Ichika's suicide, though μ makes it clear that Thorn has done this multiple times and heals her. Second time is after being defeated in Grand Guignol, when she chooses to fulfill the promise of dying alongside Ichika, which Shogo never managed to do. Third time occurs in the bad ending, where she throws herself off the Landmark Tower because her desire to destroy the real world has been fulfilled.
  • Five Stages of Grief: Has remained on Stage 2 — Denial — over Ichika's death for the past thirteen years.
  • Gender Bender: Played with, as Natsume is male, but has a feminine appearance in Mobius. Though as the scene in the Hot Springs implies, perhaps only the superficial parts were changed to look like Ichika.
  • Gender-Blender Name: Asuka is a female name, but Thorn is actually a man.
  • Greater-Scope Villain: She was the one to give μ the idea of gathering the Ostinato Musicians, using their concerts to have μ collect as much negative energy as possible, which lead to her having a warped view of the world and following Thorn's wish of destroying the real world. She also used her desires to take on the appearance of Ichika and keep the Landmark Tower a construction site, just like it was when Ichika committed suicide, so she could turn Mobius into Shogo's personal hell and keep mentally and emotionally torturing him over abandoning Ichika.
  • It's Personal: Her slight with Shogo.
  • Kick Them While They Are Down: After Lucid defeats the Go Home Club, Thorn starts kicking the beaten Shogo and demands to know 'why', referring to Ichika having asked Shogo to commit suicide with her and not Thorn.
  • Kill 'Em All: After the Go Home Club thwarts the Musicians repeatedly and Thorn ends up from overexposure to the negative energy that μ is building up, she decides to forego the inital plan of brainwashing them back into mindless citizens of Mobius and outright tells the Musicians to just kill them already. Most of the Musicians were not happy with this idea.
  • Laughing Mad: The anime has her shoot lances everywhere while laughing maniacally. She only stops when Shogo tackles her, and both end up knocked into the void.
  • The Leader: Ruler of the Ostinato Musicians.
  • Leitmotif: Distored✝Happiness. The lyrics portray all of Thorn's twisted and unrequited love for Ichika, seeing Mobius as an 'everlasting garden' she can remain living in, while also bluntly calling out the Go Home Club why they want to return to the real world, where they were so unhappy to begin with.
  • My God, What Have I Done?: After being defeated, the Catharsis Effect calms Thorn down and has her realize how twisted her views have become, and asks the Go Home Club to stop μ before it's too late.
  • Older Than They Look: Actually 30 years old, but 18 in Mobius.
  • Omnicidal Maniac: Desires the destruction of the real world, which would end up killing everyone in Mobius because dead people cannot live in the fictional place. The bad ending has her suceed, thanks to the protagonist's actions.
  • Red Eyes, Take Warning: The final boss and actual threat of the game has red eyes, which end up making a startling contrast next to her dark hair and clothing.
  • Replacement Goldfish: Her Character Episodes make it clear that the outings are recreations of events Thorn participated in. She plays the role of Ichika, while Lucid is Shogo.
  • Single-Target Sexuality: Implied to have it towards Ichika because he never fell in love with anyone after she committed suicide. In a WIRE message where the protagonist asks what Thorn's type or ideal lover is, she responds that it's a stupid question to ask.
  • Spared by the Adaptation: Implied to have survived the events of the anime, as Aria manages to save her and Shogo from falling or disappearing from existence.
  • Triang Relations: Implied to have been in a Type 4 with Shogo and Ichika. All three of them were friends and Natsume loved Ichika, though it's unclear what Ichika actually felt. Though Natsume believes that she loved Shogo because she asked him to die with her, and not Natsume.
  • Villainous Friendship: Shares a relationship of mutual trust with μ and provides most of her music. Going through her Character Episode has her also form a friendship with Lucid.
  • Walking Spoiler: Talking about Thorn ends up revealing late-game spoilers.
  • Yandere: Willing to destroy the real world because it lead to Ichika killing herself, and μ was incapable of recreating a copy of Ichika for Thorn to focus on in Mobius.
  • You Can't Go Home Again: Anytime a Musician fails in their task, Thorn threatens them with expulsion out of Mobius and being thrown back into reality.

How well does it match the trope?
