List of characters for Shin Megami Tensei III: Nocturne.
The Demi-fiend/Naoki Kashima/Shin Managi
Voiced by: Jun'ya Enoki (Japanese), Christian La Monte (English)
He was originally a normal high school student until he was caught at the eye of the Conception and dragged into the Vortex World. During this time, he is found by the Young Child and forcefully implanted with a parasite known as a Magatama. This transforms his body into a demon, while his heart remains human.
He soon discovers that his identity in the Vortex World is the "Demi-fiend"note , a prophesied figure said to hold the key to the Vortex World's recreation.
The Demi-fiend also makes appearances in Digital Devil Saga, Shin Megami Tensei IV: Apocalypse, and Shin Megami Tensei V; for information on his appearances in these games, please see Characters.Digital Devil Saga, Characters.Shin Megami Tensei IV Apocalypse, and Characters.Shin Megami Tensei V respectively.
- Alternate Self: The Demi-fiend that appears in Shin Megami Tensei IV: Apocalypse is actually a version of him that chose the True Demon path, but was unable to defeat Lucifer after killing Kagutsuchi. Defeating Stephen allows him to return and defeat Lucifer and become the Champion of Chaos he was born to be. He represents choosing the "Chaos" route of SMT, possibly his most famous ending.
- And Your Reward Is Clothes: Subverted. During a New Cycle, you have the option of giving him a leather jacket instead of the hooded jacket at the start. The costume change only lasts until the Conception (about fifteen minutes), but the true effect of the new jacket is reflected in the status parameters, which will be slightly different than the base stats of the hooded jacket (the leather jacket has slightly more magic and less strength).
- The Anti-Christ: The True Demon Ending has him become this.
- Arrogant Kung-Fu Guy: He's easily the cockiest of the messiahs in Shin Megami Tensei IV: Apocalypse. Then again, unlike the others he did destroy Kagutsuchi before being wrecked by Lucifer.
- Asskicking Equals Authority: In the True Demon Ending, you can become Lucifer's general, with your interview process being beating the crap out of the fallen angel himself.
- Berserk Button: In his position as Digital Devil Saga's Bonus Boss, he hates, hates, HATES element-nullifying skills, to the point where if it's his turn and you have any of them in your current skillset, active or not, he'll just throw Gaea Rage at your party for an instant Game Over.
- Blood Knight: His portrayal in Shin Megami Tensei IV Apocalypse, where he's exceptionally eager for a fight and wants a rematch with Lucifer, seeing as how he lost in his timeline.
- Blow You Away: Though the player can choose to go for a variety of builds, he can learn the high-damage Tornado spell much sooner than the equivalents of other elements, and the mega-damage Wind Cutter is his strongest elemental spell other than the very costly Megidolaon.
- Body Horror: Inverted or subverted depending on your views. He gets the body of/is forcibly transformed into a demon from ingesting a Magatama, which made him into a Walking Shirtless Scene with Power Tattoos covering his body and a horn on the back of his neck. He does have a nice physique as well. It's only mildly played straight when you realize what they actually are. According to the devs, the horn is actually an organ that is the source of the Demi-Fiend's power and the tattoos are actually demonic lymphs. The only reason it's "mild" is that it's easy not to notice this at first glance.
- Bonus Boss: Serves as an optional, extremely difficult battle in Digital Devil Saga, Shin Megami Tensei IMAGINE, and Shin Megami Tensei V.
- Breakout Character: He has become the most recognizable Megami Tensei protagonist, and is prone to making Previous Player Character Cameos and Bonus Boss appearances in later titles.
- Canon Identifier: In his appearances outside Nocturne, he is invariably referred to by the title Demi-fiend.
- Canon Name: Naoki Kashima in the radio dramas. Shin Megami Tensei IV: Apocalypse seems to have gone back on this, as in that game he's simply called the Demi-Fiend.
- The Champion: For whatever Reason you choose to pursue in-game. Including for Lucifer and Chaos in the True Demon Ending.
- Character Alignment: His In-Universe alignment even before becoming the Demi-Fiend is Chaos, which is only seen by observing his world map icon in normal Tokyo as it turns counterclockwise.
- The Chosen One: There's a prophecy that the Demi-fiend will be the one to choose the new world that will be born, and thanks to the Blond Child, you are that Demi-fiend.
- Contrasting Sequel Protagonist: In more ways than one:
- The previous Mainline protagonists were regular humans who utilized COMPs, effectively magical computers, to summon and contact demons. The Demi-fiend is, as his title suggests, a half-demon, half-human who uses his demonic power and tattoos for the same purpose as the COMPs.
- Previous protagonists utilized both swords and guns during combat, the Demi-fiend's Weapon of Choice are his bare fists. This is also the first mainline game in which the protagonist is capable of using spells and skills like the Demons.
- The Hero of Shin Megami Tensei I leaned towards Neutral, Aleph from Shin Megami Tensei II leaned towards Law, the Demi-fiend himself leans towards Chaos.
- Deadpan Snarker: In contrast to the two protagonists before him, the Demi-fiend has more than a few dialogue options that allow him to snark with the best of them.Yomotsu-Shikome: *sigh* I'm nothing but an old hag to you, aren't I?
Demi-fiend: More like "old bag".
- Demon of Human Origin: Before the Conception, he was just an ordinary kid; then the Blond Child shoves a Magatama into his eye, turning him into the half-human half-demon Demi-fiend. The True Demon ending sees him completely forsake his humanity to become the newest general of Lucifer's armies.
- Did You Just Punch Out Cthulhu?: Aside from beating the crap out of several mythological figures around the game, you get to defeat Kagutsuchi - responsible for the world's rebirth - at the end of the game. And if that wasn't enough, if you went for the True Demon Ending, you fight Lucifer right after. And then you finally go for God in the ending.
- The Dragon: In the True Demon Ending, the Demi-Fiend becomes this to Lucifer, being Lucifer's general in the final battle against the Great Will.
- Eye Scream: The Blond Child turns him into the Demi-fiend by dropping a squirming, burrowing Magatama directly into his eye.
- Expy: Of Akira Fudo from Devilman. The Demifiend is an ordinary Japanese youth turned into a Half-Human Hybrid of man and demon by a blonde child that is really Lucifer in disguise.
- Faustian Rebellion: Actively enforced by Lucifer, whose final test for the Demi-Fiend, in the True Demon Ending, is to use the power he gained in the Vortex World to defeat the Fallen Angel in battle, and prove himself worthy of being the general of the army of Chaos in the final showdown with the Great Will.
- Four-Philosophy Ensemble: As the only one who can't create a reason or isn't responsible for making one, he befits as the fifth member of the ensemble, the Conflicted. He's noted for being a badass who cannot create a reason of his own, and must follow one of the established Reasons to recreate the world. Or not. You can subvert this trope by taking the True Demon Ending or simply not choosing any Reason to support.
- From Nobody to Nightmare: Started off as just an Ordinary High-School Student who was in the wrong place at the wrong time, and becomes one of the most singularly powerful entities in the universe, going so far as to either reshape the world or destroy it completely.
- Good Old Fisticuffs: Unlike other protagonists of the Megaten franchise, he has no weapon. No sword, no gun, not even knuckles (though he can create a Laser Blade with a few physical skills). He's capable enough to punch demons to death with his bare hands.
- Half-Human Hybrid: Part human, part demon. Unless he becomes a True Demon.
- He Knows Too Much: Comes very close to getting murdered by Hikawa in the prologue for stumbling onto his operation, until Yuko intervenes on his behalf.
- Hello, [Insert Name Here]: Part of the Megami Tensei tradition. According to the radio dramas, his name is Naoki Kashima.
- Iaijutsu Practitioner: When using his Deadly Fury skill, he summons a Laser Blade behind him, and slashes it like a Samurai using Iaido.
- In Their Own Image: His transformation into the Demi-fiend was done for this purpose and to inherit the will of Lucifer. This is also why he gets compared to him in the Freedom ending since he follows the path of Freedom rather than the will of others.
- Laser Blade: He makes one when using a skill that requires a weapon.
- Logical Weakness: In his Super Boss appearances, he's immune to everything except Almighty, as well as attacking elements not present in Nocturne, meaning Earth (in Digital Devil Saga) or Guns (in SMT IV).
- Magic Knight: You can make him this, unlike the previous two protagonists.
- Meaningful Name: As explained by the game creators, the protagonist's new moniker in Vortex world is meant to reflect him becoming a human heart in a demonic skin. Thus the original "Hitoshura" (人修羅) is a combination of the words for "human" (人間) and "asura" (阿修羅). The asura being a group of deities or sometimes demons in Hinduism and Buddhism most commonly associated with war and violence. The English Woolseyism "Demi-fiend" meanwhile similarly combines "demi" from the part-human / part-divine demi-god concept, and "fiend", another synonym for a demon as well as a word often associated with extreme cruelty.
- Mr. Fanservice: Weird tattoos and bright amber eyes aside, he's a handsome young man who spends most of his screentime across the franchise shirtless.
- Mythology Gag: The demon motif in his jacket sleeves are icons that were used to indicate demon numbers and status in the classic Megami Tensei games.
- Nice Guy: Isamu says he is trusting and naive, though whether he is or not... depends on you. Turns into Beware the Nice Ones when he starts making a name for himself as a badass.
- Nigh-Invulnerable: The Demi-Fiend's final Magatama is the Masakados Magatama which gives him an enormous stat boost and renders him immune to everything except Almighty attacks. This attribute also likes to get carried forward into his cameos in later games.
- No Canon for the Wicked: Implied subversion, Demi-Fiend apperances in other Megami Tensei games consistently portray him as someone who has chosen to follow Lucifer in the True Demon Ending; in IV: Apocalypse he gets pulled from suffering a defeat against Lucifer and IMAGINE has him working as Lucifer's general.
- Non-Indicative Name: Once the Demi-fiend becomes a true demon, the "demi" part of his name loses all meaning.
- One-Hit Kill: His Gaea Rage gets upgraded to this in Digital Devil Saga when you fight him as a Bonus Boss. It's not a proper instant kill (it does Almighty damage), but the damage is so high (four digits at best in a franchise where player characters cannot exceed 999 HP) that it effectively is one.
- Otaku: Though his personality is basically up to the player, Chiaki's insult around the beginning of the game would suggest that he likes video games and dabbles in the occult.
- Oxymoronic Being: Shin Megami Tensei IV Apocalypse's DLC, Messiahs of the Diamond Realm, implies he is one of these. The Demi-Fiend is a Fiend, a class of demons which specifically represent death, destruction, and end of all things, but he is also a Messiah, a special human who is meant to liberate humanity and decide their future. As humanity cannot have a future and die at the same time, it's suggested Demi-Fiend is stuck between two extremes. On a glance, the ending which the player chooses seems to determine which nature he ends up following; if he goes the Neutral route then he will follow his nature as a Messiah by restoring the world from before the Conception, but if he goes through True Demon Ending then he will fulfil his nature as a Fiend and bring the end to the cycle of death and rebirth of universes perpetuated by Kagutsuchi. However, given Stephen is indirectly supporting Demi-Fiend's True Demon choice in the Diamond Realm, and the fact he only supports Messiahs whose actions are in humanity's best interests, this suggests even if Demi-Fiend follows his nature as a Fiend he still somehow helps humanity one way or another note .
- Person of Mass Destruction: He spends the entire game gaining more power and slowly evolving from a wimpy high school student to one of the most powerful beings in existence. Depending on how you interpret the True Demon ending, he may end up being the most powerful being in existence, capable of killing God himself. Mass destruction is putting it lightly.
- Physical God: One of the higher-ranked titles he can get in the game, Spirit, is the translation for Godly Spirit, aka the race Godly that YHVH and his avatars make up. Also, he can beat up the ACTUAL God in the True Demon Ending.
- Power Echoes: In Shin Megami Tensei IV: Apocalypse, he finally gets a voice that echoes whenever it speaks.
- Power Tattoo: Gains tattoos as by-product of absorbing the demonic powers of the Magatama. Interestingly he loses his tattoos, but not all his powers, in the Freedom ending.
- Previous Player-Character Cameo: Makes an appearance as a Bonus Boss in Digital Devil Saga: Episode 1, where he is infamously hard. He follows this in Shin Megami Tensei IMAGINE by having two boss battles against him. One as an event boss for the game's fifth anniversary and the other as a boss in the Abyss Tower. He also makes an appearance in the last piece of DLC in Shin Megami Tensei IV: Apocalypse.
- Pro-Human Transhuman: In the Freedom Ending, he uses his demonic powers to restore the world to the way it was before the Conception and bring freedom back to humanity.
- Red Eyes, Take Warning: In the True Demon Ending, after becoming a full demon, his usual gold eyes turn bright red.
- Red Baron: His highest title King (Chaos King in Japan) is the highest-ranked title in the game. It stands above even Godly. This title is even part of his name in one of the IMAGINE battles against him.
- Signature Move: He has several skills only he can learn. All of which turns his skin dark, emphasizing his Glowing Eyes of Doom and tattoos.
- The Stoic: He doesn't emote much, and his dialogue leans heavily towards an unfazed Deadpan Snarker.
- Take a Third Option: The Demi-fiend is incapable of creating a Reason due to not being human anymore, and thus has to follow one of the other reasons someone else makes in order to bring back the world. Of course, just because he can't create a Reason doesn't necessarily mean he needs one if he wants to destroy the world. If you go Reasonless or for the True Demon Ending, you can indeed take the third option and destroy everything, going after God himself.
- Übermensch: The Demi-fiend's journey through the story mirrors Friedrich Nietzsche's writings on the concept of ubermensch in Also sprach Zarathustra. This includes the Demi-fiend's harrowing journey, his encounters with Zoroastrian deities, and him overcoming an aspect of God to create a reason and morality of his own.
- Unskilled, but Strong: As can be surmised from his attacking animations, he's never had any formal training. That said, he eventually becomes a massively powerful force, powerful enough to in the True Demon Ending, beat down Lucifer, and become Lucifer's general in the final war against God.
- Unwitting Pawn: Because of Lucifer's feeding of the Magatama, he's forbidden to create a reason. True to form in game, almost all of your actions and directions are little more than orders barked to you by one of the reason holders ("Go to Ginza" "Rescue Futomimi" "Save Ms.Takao!") One interpretation of his character, and even lampshaded by Isamu at one point.
- Walking Shirtless Scene: Interestingly enough, according to Word of God this was inspired by, of all things, the Red Hot Chili Peppers.
Humans and Manikins
Voiced by: Suzuko Mimori (Japanese), Laura Post (English)
A teacher at the high school that the main character attends.
She is popular with the students because she emphasizes logical thinking over rote memorization. She joins forces with Hikawa to bring about the Conception because she is tired of the world, which she sees as full of people meaninglessly wasting their potential, without the energy or drive to make a difference.
- Be Careful What You Wish For: She jumped at the opportunity Hikawa gave her to "become the pillar of the new world"... and she literally ends up as one to help drain Magatsuhi as part of Hikawa's Nightmare System.
- Big Good: Subverted. She appears set up to be one from the beginning, and the earliest portions of the game are devoted to finding her in a desperate attempt to understand what's happening in the Vortex World. However, Yuko's inability to find a Reason means she is unable to truly create a world of her own, leaving her unable to offer any real guidance to the Demi-Fiend or oppose the other Reasons.
- Broken Bird: Yuko is jaded and tired at the world, to the point where she joined up with Hikawa to start the Conception. Should you get the Freedom ending, she gets over it.
- Create Your Own Villain: She willingly brought the protagonist and his friends along when the Conception occurred on the hopes they would be able to do what she couldn't. This ended up causing Chiaki and Isamu to develop their own twisted philosophy on how the world should be.
- Demonic Possession: A being known as Aradia tend to possess her from time to time, mostly for the sake of communicating with people other than Yuko.
- Fatal Flaw: Lack of self-esteem in her own power and ability to change the world. This causes her to be easily swayed by those who possess the confidence and conviction that she lacks, such as Hikawa. In her mind, she was only one small person unable to make a significant difference to a big world. In reality, she was well respected by her students and was already influencing their lives in a positive way: a good example of this is Chiaki's desire to ask Yuko for advice on what she should do after graduation.
- Flat Character: This is her main character flaw. At the end of the day, she doesn't really have any real desires of her own nor a strong drive to see them through; as a result she gets easily manipulated left and right. In the end it is also the leading cause as to why she is unable to forge her own Reason.
- Four-Philosophy Ensemble: Between herself and the other human main characters, she takes the role of The Realist. She eventually wants the world to go back to how it was as opposed to ideals the others have.
- Heel Realization: In the Freedom ending, she realizes her pessimistic views of the world were wrong and thanks the Demi-fiend wholeheartedly.
- Irony: She actually can create a Reason of sorts (posthumously) for the Demi-Fiend, provided that he chooses the Freedom ending: Recreate the old world.
- Locked Out of the Loop: She isn't aware that she is the one that has to establish a Reason, not vice versa. Of course, no one ever told her that.
- Meaningful Name: Yuko's given name is written as "祐子" which mean "divine protection" and "child". This is indicative of her status as the Maiden. Or so we're led to believe. In actuality, instead of being a maiden that would help shape the new world, she would end up being a sacrificial maiden instead.
- Powered by a Forsaken Child: Hikawa uses her to power The Nightmare System to absorb Magatsuhi.
- Psychologist Teacher: Subverted. Yuko's students praise her for her guidance, but she herself is struggling with her own lack of confidence.
- Sacrificial Lion: She's Shijima's, fading to nothing as Ahriman is summoned.
- Unwitting Pawn: Not just by Hikawa, but implied to be Aradia's pawn in an attempt to gain power and become a real being.
- Willing Channeler: Chooses to let Aradia possess her.
Voiced by: Reina Ueda (Japanese), Carla Tassara (English)
A classmate of the main character.
Born and raised in an upper-class family, she has a habit of talking down to people. Like Isamu Nitta, she is also drawn to the Conception. Though confused and scared at first, she quickly adapts to the law of the Vortex World and resolves to find answers with her own power.
- Aesop Amnesia: She doesn't learn from her near-death experience from Sakahagi that her philosophy won't spare her if she loses.
- Action Survivor: Heavily implied as she explores the Vortex World alone, with possibly no demon partners or powers. She even survives confronting Sakahagi and even manages to escape and reach Gozu-Tennoh's room on her own.
- Alpha Bitch: As the game goes on, she becomes more and more like this, believing in creating a beautiful world where she reigns supreme in a world of Might Makes Right. It doesn't help that she's noted to have looked down on others before the Conception occurred.
- An Arm and a Leg: Meeting and trying to fight Sakahagi over Magatsuhi ends with her getting her right arm cut off.
- The Beautiful Elite: She goes on about power and beauty going hand in hand when talking about her Reason of Yosuga.
- Break the Cutie: She's genuinely scared/much, much nicer during the start of the game, but after having found her Reason and getting her right arm blasted away, added with the pressure of surviving the Vortex World, she quickly hardens into something much worse.
- The Chooser of The One: In the Yosuga ending, she realizes that her destiny wasn't to create the world of Yosuga, but to choose you so that you could get the job done.
- Deal with the Devil: Taking in the spirit of the fallen Gozu-Tennoh finally gives Chiaki the power she wanted, but the act corrupts her further and amplifies her negative traits, changing her from a haughty teenager to bloodthirsty demon that's always hungry for power.
- Dub Name Change: Her last name was changed from Tachibana in the Japanese version to Hayasaka in the English version because of character limits. HD Remaster undoes this, making Tachibana her English surname as well.
- Eldritch Abomination: Her god that she summons and becomes is Baal Avatar.
- Evil Cannot Comprehend Good: After being defeated she fails to comprehend why someone strong wouldn't want a darwinist world.
- Evil Makes You Ugly: While she would disagree and likens beauty and power as one and the same, her fusion with Gozu-Tennoh makes her look inhuman, as it whitens her hair, covers half her face in a bark-like substance, and gives her a new right appendage that looks less like an arm and more like a mass of squirming ethereal tentacles. When Chiaki transforms into Baal Avatar, she looks more like a statue carved by an entity with a poor grasp over what a human actually is.
- Fantastic Racism: Definitely seems to have picked this up against Manikins, not helped by a particularly psychopathic one taking her right arm. This reaches a breaking point when she slaughters them en masse to take their Magatsuhi and create her Reason of Yosuga.
- Fantastic Slurs: She refers to Manikins as "Mud Dolls".
- Fatal Flaw: Chiaki doesn't seem to realize that she'll be constantly fighting in order to stay alive and not be rendered useless in her new world. Even on her own route she is subject to the logic of her very own Reason and has to submit to one who's bested her in a fight — the Demi-Fiend, in this case.
- Final Boss: If Isamu/Noah is fought beforehand as intended, she's the last boss fought in the Demon ending, as Kagutsuchi will refuse to fight you should you pick that path.
- Four-Philosophy Ensemble: Between herself and other possible Reason makers, she applies as the Optimist. Her Reason of Yosuga is a philosophy of Might Makes Right and Social Darwinist philosophies, which seems to fit with the lack of forethought and disregard for consequences given how she doesn't realize the rules apply against her, and also the Black-and-White Morality in the form of "The strong" being the White and "The weak" being the Black.
- Fusion Dance: With Gozu-Tennoh, after he sympathizes with her philosophy and urges her to carry his spirit, as he will not be able to act at all as his body is dead. This gives her monstrous strength and grows her a new arm as well.
- Heavenly Blue: The color of her clothing, and the color of the Technicolor Fire after she takes over the Mantra's Headquarters. It befits how she gains angels as her allies.
- Hypocrite: Despite following a philosophy of Might Makes Right and being a Social Darwinist, Chiaki is a weak individual who only gains power when she finds an entity far stronger than herself who sympathizes with her ideals enough to offer her a Deal with the Devil. Even during her boss battle, she can't beat the Demi-fiend by herself and thus summons two other allies to assist her.
- It's All About Me: Her Reason is rooted in creating a world where all must submit to her rule due to her being the most powerful. Even before the Conception begins, she's hinted to have a bit of a selfish streak when she considers asking Yuko for advice on her career despite her teacher being in the hospital at the time.
- Jerkass Has a Point: She despises Manikins, and kills a good majority of them to claim their Magatsuhi. She justifies her actions with the claim that they never could create a new world themselves. As those who've played through the Labyrinth of Amala know, she's actually somewhat correct. The Lady in Black explains that Manikins are remnants of human souls and emotions from the previous world, and cannot conceive a Reason of their own.
- Kill the Poor: This is, basically, what the Reason of Yosuga is.
- Light Is Not Good: Yosuga is hands down the most violent and malevolent Reason in the game, but the faction that she leads mostly consists of angels. Chiaki herself takes on a bright, angelic form when she transforms into Baal Avatar, as she goes even further off the deep end.
- Meaningful Name: Chiaki is written like "千晶" meaning "a thousand crystals/diamonds", reflecting her coming from a rich family.
- Mystical White Hair: Chiaki gains this trait upon absorbing Gozu-Tennoh's power. Also a case of White Hair, Black Heart.
- The Ojou: Is noted to have come from a high-class family and is used to getting what she wanted.
- Only Sane Woman: From what little we see of her pre-Conception, Chiaki has immediate misgivings about the Shinjuku Medical Center and wants to leave as soon as possible.
- Pet the Dog: Notably, she seems to have some affection for the player character. She's the first to call and ask where he is when he's late to arrive at the hospital, encourages him and Isamu to think about their lives after graduating, and is the most receptive to the Demi-Fiend in their first handful of encounters.
- Politically Incorrect Villain: Classism is her Reason's defining trait.
- Red Right Hand: She gains tendrils to replace the arm that she lost to Sakahagi.
- Social Darwinist: Her Reason of Yosuga in a nutshell - the strong should thrive and be on the top and the weak must die. To prove her point, she massacres the Manikins for being weak and useless, and to take their Magatsuhi to call down her god.
- Slowly Slipping Into Evil: She still seems relatively decent at the beginning of the game, having been shaken up by the Conception, but hoping to find something to salvage from it. However, Chiaki very quickly develops a strongly Darwinian Reason, and in the scenes leading up to her next appearance, pretty much everyone comments on the great evil they sense growing within her. She jumps off the slippery slope once she accepts Gozu-Tennoh's power, and her genocide of the Mannikins shortly afterward shows she has reached a point of no return.
- Supernatural Gold Eyes: After she gains her demon form.
- There Can Be Only One: Even if you have sided with Yosuga, she challenges you after beating the rest of the Reason bosses, stating that only one of them can lead the new world.
- Took a Level in Jerkass: At the beginning of the game, Chiaki was critical and a bit haughty at worst. By the time she forms her Reason, she becomes a full-on darwinist and wants to rule a world where the strong prey on the weak.
- Took a Shortcut: Many times throughout the early portion of the game, several demons see her traveling the same areas the Demi-Fiend traverses, seemingly ahead of his progress without powers or a demon of her own.
- Transhuman Treachery: Even before she calls upon her Demonic Sponsor, Chiaki has already fused with the remains of a powerful demon, making her at most a third human. In a game as morally apathetic as Nocturne where concepts of right and wrong no longer exist, Chiaki is the only character in the text explicitly described as "evil."
- Unlucky Childhood Friend: If Isamu in the Drama CD is to be believed, she and the Demi-fiend had a very close relationship, and probably would have started a romance if not for the Conception.
Voiced by: Takuya Eguchi (Japanese), Robbie Daymond (English)
A classmate of the main character.
He has a relaxed personality; however, he has a tendency to be cocky. He is also very fond of his teacher, Yuko Takao. Before the Conception, he is confident and independent, shown by him going off on his own to search the deserted hospital for his missing teacher. In the immediate aftermath of the Conception, however, he struggles to cope with the new world and instinctively seeks out Yuko and the main character for support and help.
- A God Am I: After he absorbs the souls of the Amala Network, he declares himself as "the Almighty Isamu, Master of Amala's Power".
- Batman Gambit: Manipulates Hijiri (for constantly surveying the world via the Amala Network) and the Demi-fiend (who he sees as an easily manipulated Unwitting Pawn) in a plan to summon his God Noah.
- Body Horror: Once he absorbs souls from the Amala Network, he becomes a Walking Shirtless Scene that has multiple fleshy growths covering his body with the most prominent of them looking like screaming faces.
- Break the Cutie: Male variant, but much like Chiaki, he was a fun, easy-going guy until the pressures from the Vortex World combined with failed attempts at finding other people caused him to shut down and withdraw; leading to him forming his own reason.
- Bullying a Dragon: His behavior post-jerkassdom has him mocking the Demi-fiend for being gullible, easily used and whatnot. Mind that you can still reject his Reason and kill him.
- Complaining About Rescues They Don't Like: His first reaction to being rescued from Kabukicho Prison, which would be the second time he was rescued from a mess he got himself into, is to angrily berate the Demi-Fiend for failing to save him in time.
- Eldritch Abomination: The god he summons is Noah, a nameless wandering god outside of time.
- Eviler Than Thou: Just as Hijiri believes he is about to use his mastery of the Amala Network to defeat all the other Reason bearers and create his own world, Isamu turns the tables on him and uses his superior control over Amala to turn Hijiri into a sacrifice to his sponsor god.
- Final Boss: Should you choose to ignore him and kill Chiaki first, he's this for the Demon ending as Kagutsuchi doesn't fight you.
- Four-Philosophy Ensemble: Between himself and the other Reason creators, he takes the place of the Apathetic. He doesn't care about other people and thinks it would be best if they were all left to live alone, and eventually showing that he doesn't even care about whether he lives or dies, if the Demi-fiend carries out his wishes or not, and that he wanted to be able to live without dealing with any consequences to his actions forming his Reason of Musubi.
- Fusion Dance: After going into the Amala Network and getting loads of Specters crammed into his body, he becomes stronger.
- Hero Killer: Isamu is ultimately the one to kill Hijiri, the closest the player has to an ally for much of the game.
- Isamu does not seem to be aware of the inherent contradictions between his philosophy and actions. He proclaims that individuals should be inherently isolated, but constantly relies on other characters (the player in particular) for emotional support, help, and power in establishing his Reason. He even uses you and Hijiri to gather enough Magatsuhi in order to even summon his god. Isamu is ultimately spoiled: his desire for a world of Musubi is not because he believes in his Reason, but because he wants a world where he can do whatever he wants without consequence. This is demonstrated after his death, in which he proclaims that he simply doesn't care if the Demi-fiend carries on his wishes or not.
- He also states that he can't count on the Demi-Fiend or Ms. Takao for help in anything after being freed from Kabukicho Prison... despite the fact that he decided to go there alone in search of answers and didn't think to accompany the Demi-Fiend, as it'd be safer.
- It's All About Me: His Reason is to live in a world devoid other people, who he admits to never really caring about, implicitly so he can do whatever he wants without consequence. Even before the conception, a little bit of this selfishness peeks out when he insists that he has to be the one to find Yuko, and treats the Demi-Fiend like a sidekick as a result.
- The Load: Until he gains access to the power of Amala, Isamu's attempts to find a Reason result in him constantly needing the Demi-Fiend's help to escape his predicaments.
- Made of Iron: He, as a normal human, manages to survive getting casually swatted aside by Thor's hammer. Sure, he still gets knocked out, but that's better than being outright killed.
- Nice Hat: Never seen without his distinctive cap. Even his god, Noah, has it on when it forms his face.
- Non-Indicative Name: Isamu's given name (勇) means "brave". However, he's actually a coward, relying on others while hypocritically proclaiming that everyone should be isolated.
- Plucky Comic Relief: Deconstructed. Isamu initially has the appearance of one. He says all the funny lines, gets into the hilarious hijinks, and comes across as the Wise Guy to Chiaki's Straight Man. However, losing everyone and everything he's ever known in the Conception makes it impossible for him to maintain his sense of humor, and being captured, imprisoned, and tortured by demons multiple times drains his spirit, and being valued less by his teacher than the Demi-Fiend makes him bitter and resentful, and drives him down a path of villainy.
- The Resenter: He grows steadily more resentful of the protagonist, in large part because Ms. Takao seems to prefer the latter over him.
- Skippable Boss: An odd temporary case. Unlike Ahriman, Noah isn't directly on the path leading to Kagutsuchi, so it's possible to ignore him, head upstairs to the Manikin town, and even take out Thor and Baal Avatar first, but it's ultimately subverted as you still need his Netherstone to reach Kagutsuchi.
- Stopped Caring: After being beaten.
- Student/Teacher Romance: Seems to have an unrequited crush on Ms. Takao.
- Too Dumb to Live: Right after getting out of the Mantra's Prison, he decides to head off to Kabukicho Prison to find Futomimi, despite having just gone through torment at the former already. He proceeds to get imprisoned once more.
- Took a Level in Jerkass: He starts as a Jerk with a Heart of Gold, but after the Demi-Fiend saves him in Kabukicho, the Jerkass part of his personality becomes more prominent while the heart of gold shrinks away.
- Walking Shirtless Scene: After absorbing souls in the Amala Network... though considering what's underneath, you'd probably wish he wasn't.
- The Worf Effect: If you side with his Reason, he'll be killed offscreen by Chiaki.

Chief Technical Director of a large communications company called Cybers, and a high-ranking officer of the Gaea cult.
He is said to be the one actually responsible for the occurrence of the Conception. After the emergence of the Vortex World, he organizes the Assembly of Nihilo, which becomes one of the two strongest demonic forces (the other being the Mantra). His dream is a World of Silence, where the dangerous passion of man is neutralized, and everyone is at one with the world: this, he calls the Reason of Shijima.
- Affably Evil: While he tries to kill you in your first couple encounters with him, Hikawa does begin to show a more civil side from then on, arguing his points and even showing respect if the Demi-Fiend actually voices agreement with and ultimately sides with him.
- Ambition Is Evil: As part of a speech he gives when trying to convince the Demi-fiend to embrace his philosophy of Shijima, Hikawa likens human ambition and greed to fire; acceptable in small amounts, when they can provide warmth and comfort, but humans let them grow out of control until they consume everything around them.
- And Then What?: He is the only one of the three Reason leaders to survive in his ending. Having won, he states that he's content to live the rest of his days in a quiet corner of the world that the Demi-fiend creates.
- The Bad Guy Wins: If The Demi-Fiend sides with him, Hikawa succeeds in creating his World of Shijima.
- Bait-and-Switch Boss: After he delivers his speech to you upon meeting in the Assembly, he deserts and leaves behind Ose, one of his servants.
- Big Bad: He is the one who forced the Conception to occur and his Reason of Shijima is the one The Demi-Fiend along with Hijiri and Yuko are actively battling against.
- Breaking Speech: He gives one when you visit him in the Assembly of Nihilo, saying that the Demi-Fiend wasn't meant to survive the Conception, that all of your hopes are for naught and that it was better if you died now. He later gives one to Ms. Takao before he sacrifices her to summon Ahriman.
- The Chessmaster: Was said to have started the Conception. His actions from then on, including manipulating Yuko, show he's no slouch on the mental front.
- The Chooser of The One: In the Shijima ending, he realizes that his destiny wasn't to create the world of Shijima, but to choose you so that you could get the job done.
- Death by Irony: For his desire to create a World of Silence, after he's defeated as Ahriman in the Tower of Kagutsuchi, he remarks how he feels nothing, realizing the stillness of his death has overtaken him.
- Disappointed in You: Towards the Demi-Fiend should he refuse his offer and side with Yuko.
- Disc-One Final Boss: While he's never actually fought until near the end of the story, he's nevertheless treated as the Big Bad, and most of the game's first half is devoted to fighting his faction and crippling his forces. Once that is done, Hikawa's influence on the plot wanes as the other Reason holders grow in power, and he ultimately ends up becoming part of the Big Bad Ensemble with them.
- Eldritch Abomination: The god he summons and becomes is Ahriman, the god of the void.
- Evil Overlord: Essentially one for the Assembly of Nihilo, where he commands the demons.
- Exact Words: When he was getting Yuko to his side, he said "I want you to become the Pillar of the new world." He means that quite literally.
- Fatal Flaw: Despite being The Chessmaster of the events happening, Hikawa takes too long to get his plans going, and at least twice (the Assembly of Nihilio and the Obelisk) he delayed himself further by wasting the Magatsuhi he stored up. As a result, not only is he the last to achieve his god, but his is also the first to fall up the climb of the Tower of Kagutsuchi while Chiaki and Isamu have a head start ahead of him.
- Four-Philosophy Ensemble: Compared to the other Reason creators, Hikawa came up to be the Cynic. His Reason of Shijima is a World of Silence where no emotion exists and everything can live logically and peacefully. It doesn't help that he's the reason for the Conception happening in the first place.
- He Knows Too Much: He tries killing you at the start of the game for even being at the hospital. Thankfully Yuko manages to convince him not to do so.
- He was once part of the Cult of Gaea, a chaos-aligned organization. Despite this, his ideal world isn't so different from the world YHVH desires to make. That said, it's heavily implied he was using the Gaea cult for his own purposes.
- Despite wanting to create a world of silence and no free will, he's incredibly passionate about it and starts several wars in the Vortex World.
- In your confrontation with him before he summons his god, he expresses disappointment in the Demi-fiend and says "[He's] left [you] alone thus far"...despite the fact that he's attempted to kill you no less than two times and his Demons have attacked you relentlessly.
- His god of quiet and stillness has some rather loud attacks in Megidolaon and Apocalypse.
- Interestingly, Hikawa could've put himself in a much better position to the Demi-Fiend (and similarly, the player) if he hadn't kept antagonizing you. By the time Hikawa tells you his dreams and plans, you've already run afoul of him and his organization twice and probably don't really care what he has to say.
- Despite being the one to end the world and having a massive head start on his competitors in forming his Reason, Ahriman is the last of the Reason gods to be summoned and he makes the least progress in the race up the Tower of Kagutsuchi, with the Demi-fiend always taking Ahriman out first if he doesn't side with Shijima.
- It's Quiet Too Quiet: After being defeated, he realizes the stillness of death has come for him.
- Last-Name Basis: Hikawa is normally a surname in Japan, not a given name. We never know what his given name is.
- Meaningful Name: Hikawa's name is written with these kanji: 氷川. They mean "ice" and "river" respectively, which is fitting for a man who has a cold demeanor and wants a world of stillness.
- Nietzsche Wannabe: Hikawa believes that everybody has a set goal and road in life; and when it's done, it's over.
- Odd Name Out: Two-fold. He's on a Last-Name Basis and can't be renamed by the player, unlike the other three human NPCs.
- Properly Paranoid: When he first encounters the Demi-fiend before the Conception, he opts to kill him then rather than risk a potential threat to his plans (and to spare him the suffering that comes after the Conception, but mostly the former).
- Puzzle Boss: As Ahriman. He restricts certain actions during each round in his first phase, and violating them has him do a One-Hit Kill on your party.
- Sole Survivor: He's the last living member of the Cult of Gaia, although by the time of the Conception he's long since betrayed them. If the Demi-fiend aligns himself with Hikawa, he is the only Reason-bearer to survive in contrast to Isamu, who dies at Chiaki's hands in the Musubi route, or Chiaki dying to the Demi-fiend regardless of which Reason the Demi-fiend supports.
- The Starscream: He was originally part of the Cult of Gaia, but was considered a heretic even by their standards for his want of a world of stillness. Hikawa also orchestrated the massacre at Yoyogi Park prior to the Conception, having both the Cult and the Messians wiped out so as to prevent either side from hindering his plans.
- Stupid Evil: He continues to antagonize and attack the Demi-fiend even as it becomes increasingly clear he's the game's kingmaker and holds the key to recreating the world in his vision.
- Take Over the World: Hijiri believes this is Hikawa's actual motive for his World of Shijima, rather than attempt to guide humanity in a new direction.
- Uncertain Doom: In the Freedom Ending, it isn't explained what became of him. The news report from the beginning of the game still claims that he's missing, making his fate ambiguous.
- Villain Ball: He tries killing the protagonist when he arrives at the hospital and see his ritual taking place, and again at his Assembly of Nihilo after it's become apparent the Demi-fiend does have power now. Rather than attempting to play to his good graces and persuade him to his point of view, he antagonizes you for no reason other than "to end your suffering". This is more than enough reasons to reject his Reason and essentially kill him.
- Villainous Widow's Peak: Has an enormous widow's peak and is the initial Big Bad.
- World of Silence: What he hopes to achieve.
- Xanatos Gambit: He admits this was the case when the Demi-fiend storms the Obelisk to save Yuko. If the Demi-fiend died, he removed a massive thorn in his side and could continue to use Yuko to gather more Magatsuhi. If the Demi-fiend survived, it would prove that he's the one mentioned in the Scripture of Miroku, and therefore a valuable ally for Hikawa.

A writer for an occult magazine.
He meets the main character while collecting data for an article on the riot at Yoyogi Park. Even after the Conception, his sense of duty as a reporter pushes him to investigate further. He considers himself too weak to survive in the Vortex World, so he stays within the Terminal Room, studying the Terminals and their connection to the mysterious Amala Network.
Hijiri's main motivation is to discover the truth. Even after the Conception, this goal does not change. He does not pursue Hikawa because he's too weak to face him. Over time, Hijiri slowly changes his focus from trying to stop Hikawa to learning more about the Amala Network.
- Ambiguous Situation: Given the chance, would he crucify the Demi-Fiend or Isamu the same way Isamu did, or was he telling the truth when he said he wouldn't? How much does he know about his curse to record the events of every world?
- Brilliant, but Lazy: Justified. Hijiri could not affect the outcome of the world due to his curse.
- Dead All Along: He died during the Conception, just didn't realize it.
- Face Death with Dignity: He doesn't struggle or beg when Isamu is getting ready to sacrifice him. He just accepts his fate and warns Isamu that he will pay a very high price for following his beliefs.
- FaceHeel Turn: Once he masters his knowledge of the world and control over the Amala Network, it appears that Hijiri is about to turn against the protagonist once he launches into a smug spiel about how he has more of a right to remake the world than anyone else, including the Demi-Fiend. Nothing ever comes of it though, because almost immediately after that, he's snatched by Isamu and used as a sacrifice.
- Fate Worse than Death: He's able to live only long enough to observe and record the events of each new world, but is never allowed to affect them or change the outcome in any way.
- Foreshadowing: It's implied that some of the ghosts in the hospital were there before the Conception, but the Demi-Fiend couldn't see them until he became a demon. Hijiri can only see them after the Conception, because he's Dead All Along.
- Looks Like Jesus: His long brown hair and light beard give him an almost Jesus-like appearance. Symbolically, this is further proof he may be Aleph from Shin Megami Tensei II, due to him being an artificial Messiah.
- Intrepid Reporter: He was a journalist pre-Conception, but keeps investigating the world after it takes place.
- Meaningful Name: His name includes the word "Hijiri", which in Japanese characters translates to "Holy" or "Saint". It's possible he's a reincarnation of Aleph from Shin Megami Tensei II, given he was a man-made Messiah that, if going against God, was promised unimaginable suffering. Hijiri is noted to have a Fate Worse than Death which sounds like something that God would make someone suffer.
- Nice Hat: Carries a snazzy purple trilby, though he seldom actually wears it.
- No Celebrities Were Harmed: He has an uncanny resemblance to Johnny Depp.
- The Rival: After the Nightmare System is destroyed and Hikawa loses his status as the only military power in the Vortex World, Hijiri directs all his attention towards Isamu, whose presence in the Amala Network represents a hindrance to his own plans.
- Sacrificial Lion: Used as Musubi's, sacrificed by Isamu to get the last bit of Magatsuhi necessary to summon Noah. His is particularly strong because he's both the most recurring ally and the first of the sacrifices, with two more to follow.
- Unwitting Pawn: Hijiri believes he is gaining control over the Amala Network, when it turns out he's just being lured into a trap by Isamu. Furthermore, Hijiri is revealed to be a pawn for the Great Will, forced to record the events of the Conception, but incapable of actually affecting it, and having no idea of his own lack of power.

The leader of the Manikins. He has the ability to tell the immediate future. After he and the other Manikins imprisoned in Mizuchi's mirage are freed, Futomimi is grateful to the Demi-fiend.
- Back from the Dead: You can actually bring him back with the Afterlife Bell, he's from the Kishin race now instead of Corpus as in his boss fight.
- Came Back Strong: As a Kishin when brought back to life.
- Meaningful Name: Futomimi is similar to futomani, which is Japan's oldest form of divination by reading the crack patterns formed in the heated up scapula bone of a deer.
- Nice Guy: By far one of the most friendly characters in the game.
- Optional Party Member: After his death, you can use the Afterlife Bell to bring him back to life. You can then fuse him and make him join you as a party member.
- Sacrificial Lion: The last victim of Chiaki's massacre to summon Baal Avatar. Unlike the other two sacrifices, you can actually do the deed yourself if you've made certain choices; otherwise, Chiaki sics three of the Archangels while killing him herself.
- Shadow Archetype: He is one to his original self before the Conception. His original self was a delinquent who indulged in serial killing For the Evulz. Futomimi here is a compassionate person whom everyone likes.
- Shoot the Shaggy Dog: His efforts to lead the Manikins are fruitless since they can't conceive a Reason to build the new world.
- Was Once a Man: As the Fourth Kalpa's Maze of Hell reveals, Futomimi was once a serial killer who did it For the Evulz, but after meeting some girl who told him how nice it was to be loved, it evoked the strong emotion of wanting to be the kind of person who could be loved by anyone. The Conception occurred, and Futomimi was born from those emotions.

A rebellious Manikin. He is much stronger than an average Manikin, gathering Magatsuhi by skinning any Manikin he comes across. He later goes to Yoyogi Park and finds the Yahirono Himorogi, allowing him to brainwash the Fairies and summon Girimehkala, all so he can become the king of demons. The Demi-fiend later tracks him down, fighting through the tricks of the insane Fairies, and kills both Girimehkala and Sakahagi.
- Big Bad Wannabe: He holds massive power for a Manikin, is built up as the evil power that can ruin all Manikins, and obtains a MacGuffin. In the end, however, he ends up like this, and he isn't even the evil power (that is Chiaki) though you can become like him by following the Demon Ending.
- Climax Boss: He's the great evil force built up by Futomimi. It's not until after you beat him when you learn that it's not Sakahagi. It's Chiaki.
- The Dragon: He calls forth Girimehkala, who can reflect physical attacks.
- Didn't Think This Through: During his boss fight, he summons Girimehkala to fight you, not realising that he has wasted all his MP during the summon, making him completely vulnerable if the demon gets defeated (which ends up happening).
- Meaningful Name: Sakahagi is a reference to an execution technique in which all the skin is ripped off of the victims bodies, much like his MO.
- Optional Party Member: As with Futomimi, you can use the Afterlife Bell to bring him back to life, fuse him and then summon him as a party member.
- Overrated and Underleveled: He's presented as a dangerous and powerful character. Once you get to summon him as a party member, he's only level 45, has only 2 free skill slots and his skills are nothing special. Compared to Futomimi, he's virtually useless.
- Shadow Archetype: He is one to his original self before the Conception occurred. His original self was a successful businessman who presumably hadn't killed anyone. Sakahagi willingly commits murder to collect Magatsushi in hopes of being the master of all demons.
- Suspiciously Similar Substitute: To Ozawa. Both are human/human-esque criminals who stumble on a massive power source that lets them take over an entire region with brainwashing and a powerful demon, both drive one of the protagonist's friends past the breaking point and leads to them fusing with a demon, and both are easily disposed of after killing their right-hand demon after making little direct impact on the plot.
- Was Once a Man: As the Fourth Kalpa reveals, Sakahagi was once a wealthy businessman who managed to be successful in life. Money, a company and whatnot that he eventually lost it all in. He was consumed by rage towards a young man that he blamed for his misfortunes, but he never had the nerve to take revenge against him. This deep seated rage is what gave birth to Sakahagi.
- Zero-Effort Boss: For all the build-up he gets, he ultimately ends up like this. He summons Girimehkala to fight you, wasting all of his MP. After his demon gets killed, he doesn't have any MP left, and even then his physical attacks are underwhelming. He gets easily defeated.

The protagonist of the Devil May Cry series appears in the game as a guest character.
Dante is an accomplished practitioner of demon-slaying. His business of hunting devils shares the same name as his series. Wielding his custom twin handguns "Ebony & Ivory" and the large sword "Rebellion", no demon is safe from him. Dante is also half-demon himself, however, he uses his demonic powers for protecting humanity. Though he often acts cocky and can be quite a smartass, he hates evil with a burning passion.
In the Chronicle Edition, Dante is replaced by Raidou Kuzunoha the 14th. While Raidou is the default in the HD Remaster, Dante is available as paid DLC.
- Adaptational Badass: Already a formidable fighter in his own series, here he can singlehandedly take on Demi-fiend before the latter becomes a true demon at the end of Labyrinth of Amala; note at that point Demi-fiend is at least powerful enough to fight and defeat Beelzebub and Metatron. It's also possible Dante can still fight him even after that point.
- Adaptation Personality Change: His dialogue in the HD Remaster has been rewritten to bring his personality away from the stoic and sullen demeanor he had in Devil May Cry 2 and closer to the cocky and laid-back personality he has in the rest of the series.
- Awesome, but Impractical: He cannot learn Pierce, so he has trouble against Lucifer (who is basically the last real challenge in the game by the time you complete the Amala Depths). In random battles he's a godsend because of his incredible resistance to everything except almighty attacks and his affordable Almighty attack 'Showtime'. Fridge Brilliance kicks in when you realize that this is common for him. One or two demons in his games can give him trouble, but the rest of the time he deals with demons with the ease of taking out the trash. This is fixed in the DLC for the remaster with Dante's passive skill Son's Oath now adding a Pierce effect alongside 1.5x the damage to all his attacks.
- Balance Buff: In the HD Remaster, his Son's Oath skill is buffed to have Pierce, allowing him to be more than just dead weight against the True Final Boss.
- BFS: His sword, Rebellion.
- Bonus Boss: His second fight is the first of the three boss fights in the Labyrinth of Amala.
- Composite Character: He has the look and weapons from Devil May Cry 2, but his personality is like that of his Devil May Cry 1 self. Likewise, in the Remaster, his voice actor is his recurring voice from 3 onward.
- Dark Is Not Evil: Dante has a cold glare and dresses in red and black. Then theres the whole half-demon thing. However, Dante is actually a Jerk with a Heart of Gold who fights demons in order to protect humanity.
- Defeat Means Friendship: After you beat him in the Third Kalpa he'll join you in the Fifth.
- Demon Slaying: His profession, and he is good at it, as you will learn the hard way!
- Downloadable Content: In the HD Remaster, he's paid DLC.
- Guest Fighter: He's a character from a different series.
- Guns Akimbo: His guns, Ebony & Ivory.
- Half-Human Hybrid: He's part demon thanks to a demon father.
- Mutually Exclusive Party Members: In the HD Remaster, with Raidou. Before starting a new game, you have to pick whether to play the Maniax version of the game with Dante or the Chronicle version with Raidou.
- Non-Elemental: His Stinger and Show Time skills do Almighty damage.
- No-Sell: He's one of the very rare party members that are immune to Death, Expel and Status Ailments.
- One-Hit KO: Stinger has a chance to cause instant death. If it doesn't, it still deals heavy almighty damage.
- Optional Party Member: At the start of the fourth kalpa, Dante will be waiting with an offer to join you as a party member.
- Recurring Boss: He's fought twice, at least. Although any occasion other than those two necessary ones ends up in a Curb-Stomp Battle in his favor.
- Status-Buff Dispel: Holy Star, which works the same as Dekunda.
- Throwing Your Sword Always Works: Two of his techniques involve him throwing his sword: Whirlwind and Roundtrip.
- Two-Headed Coin: If you decide to recruit him, make sure to choose heads. The coin he flips is a trick coin with heads on both sides, and choosing heads will lower his fee to 1 Macca (as opposed to half of your entire wallet).
- World's Strongest Man: Is considered the strongest of all fiends.
Raidou Kuzunoha the 14th
Voiced by: Tomokazu Sugita (Japanese), Billy Kametz (English)
Gouto Voiced by: Joji Nakata (Japanese), Ray Chase (English)
Dante's replacement in the Chronicle Edition and HD Remaster Updated Rereleases.
The protagonist of Raidou Kuzunoha vs. The Soulless Army and Raidou Kuzunoha vs. King Abaddon, this young man is the newest Devil Summoner to inherit the title of Raidou. As a Devil Summoner, he has the ability to see and hear demons (which are invisible to normal people in his world), along with being able to negotiate with and capture demons to serve as his familiars. He can call on these demons for investigation and combat, as Raidou's day job is that of a detective working for the Narumi Detective Agency. His primary weapons are a katana, a pistol, and a collection of summoning tubes hidden within his cape.
Raidou is a silent protagonist, with his feline sidekick Gouto speaking in his stead. Raidou's special attacks mirror Dante's but have new names. Notably, he gains the passive ability "Pierce", a skill unavailable to Dante in the Maniax release.
- Badass Cape: Part of the school uniform he's always wearing.
- Dark Is Not Evil: He wears a black uniform, has a black cat as a sidekick, and summons demons, but is a detective who fights against demons and eldritch abominations.
- Hello, [Insert Name Here]: Raidou the 14th is his title, not his name. His real name is created by the player in his own games. That said, a piece of supplemental material does give him the first name of Jouhei.
- Heroic Mime: He never speaks himself, relying on Gouto to speak for him. Partially subverted in the HD Remaster where he does finally talk in battle with full voiced sentences.
- Hero Killer: As revealed in the post-credit scene in the True Demon Ending in Chronicle Edition and HD Remaster, the old man in the wheelchair hired Raidou to kill the Demi-fiend.
- Hot-Blooded Sideburns: He sports a pair of sideburns, and while he's rather quiet and content with Gouto doing all the talking, he's always up for a fight. In his second encounter after his boss battle, he attempts to use eight tubes before Gouto stops him.
- The Musketeer: He wields a katana and a revolver loaded with elemental bullets.
- Mutually Exclusive Party Members: In the HD Remaster, with Dante. Before starting a new game, you have to pick whether to play the Maniax version of the game with Dante or the Chronicle version with Raidou.
- Nice Hat: Part of the school uniform he's always wearing.
- Non-Human Sidekick: Gouto, who is a talking cat.
- Optional Party Member: Like Dante, you'll be able to hire him as a party member at the start of the fifth kalpa.
- Summon Magic: Like most SMT protagonists, he is a devil summoner. A majority of his skills involve pulling out the appropriate demon for the job.
- Suspiciously Similar Substitute: His skills are largely just renames of Dante's. He and Gouto even offer a similar wager when they join you, just with mahjong tiles instead of a coin, and with them paying you rather than the other way around.
- Sword and Gun: A katana and a revolver, respectively.
- Voice for the Voiceless: Gouto speaks for him.
Proprietor of the Junk Shop in Shibuya. He wants to grow strong and eventually leaves for Ikebukuro, where he contemplates joining the Mantra. He gets imprisoned by them for loitering but is let off after the Nightmare System is fired. Later on, he ingests a Magatama and transforms into Black Frost, who then freezes and takes over Kabukicho Prison, with several Jack Frosts as servants. You can then face him as a Bonus Boss who can later be recruited in the Amala Labyrinth.
- An Ice Person: As a Jack Frost, he was an ice aligned demon.
- Casting a Shadow: After becoming Black Frost, he gains the ability to cast Mamudoon.
- Evil Makeover: He becomes Black Frost with the power of the Satan Magatama.
- Optional Party Member: Shows up in the Amala Labyrinth after being defeated, ready to join you.
- Playing with Fire: After becoming Black Frost, he gets access to a few fire spells and immunity to Fire itself. As a playable character he only retains the fire immunity.
- Scratch Damage: Takes only 10% damage from physical attacks as a boss. Strangely enough, he keeps this attribute when he joins you.
- Verbal Tic: As to hee expected, he tends to inject "Hee ho!".
One of Hikawa's followers who appears with him at the Diet Building. If the Demi-fiend attempts to interfere with Yuko's sacrifice, then Samael will step forward to try and stop him. Side with Hikawa, on the other hand, and he will join you on your journey through the Tower of Kagutsuchi.
- The Dragon: Literally one to Hikawa and should you side with Shijima he'll become your dragon.
- Meaningful Name: Poison of God. His name being one reason why he is part of the Vile Race instead of the typical angel clans.
- Our Dragons Are Different: A serpent-like dragon that is also an angel.note
- Status Buff: Tends to Rakukaja a lot during his fight.
- Status Effects: His attack God's Curse can inflict different status effects onto his enemies.

Gozu-Tennoh's right-hand man in the Mantra Army and also the head jailer in Ikebukuro. He is first seen draining Magatsuhi from, and imprisoning, Isamu. Thor deserts after the Nightmare System is launched, saying that he has no interest in a dead city and that the Mantra were wrong all along. He shows up again in the Tower of Kagutsuchi regardless of your Reason and will fight you to test your strength. Thor dies after this battle.
- The Dragon: To Gozu-Tennoh and later Chiaki, sorta.
- Establishing Character Moment: His aforementioned beating-up of Isamu. To further establish his character, he throws you into prison as well.
- Graceful Loser: If you side with Yosuga, Thor still fights you to see if your strength befits a champion of the Reason. When he dies, he wholeheartedly swears his allegiance to the Demi-Fiend.
- Judge, Jury, and Executioner: The Mantra Army Court he presides.
- Shock and Awe: It's Thor, what do you expect?
- Villain Forgot to Level Grind: You fight him first in the Mantra Court, then way later in the game near the top of the Tower of Kagutsuchi. While he does gain a few tricks in between, you've likely grown way more in the interim, and he's gone from a challenging opponent from back then into a Breather Boss.
- Win Your Freedom: Sure. He can respect ya. Just prove you're not a wimp.

> You can feel the presence of a terrifying demon...
A group of demons that the Demi-fiend can encounter at various points in the game. They all hold a Menorah similar to the one The Old Man gives you, and are supposedly vying to be the one who holds all of them through fighting each other. The Fiends are, in order, Matador, Daisoujou, Hell Biker, White Rider, Red Rider, Black Rider, Pale Rider, Mother Harlot, and Trumpeter.
For the Fiends as they appear in the rest of the series, see their character page.
- Ascended Extra: In previous games, the were random Bonus Boss encounters with incredibly low odds. Here, they're required to get one of the endings.
- Bonus Boss: Aside from Matador, Hell Biker, and Trumpeter, none of the Fiends are required to beat the game unless you want the True Demon Ending. Most of them are positioned off the beaten path or require that the player trigger an event flag.
- Butter Face: Mother Harlot is described by various NPCs as a beautiful woman, however they could only get a look at her back. Once the player gets to confront her, she fits their description, until she turns to look at him, and reveals her faceless skull.
- Destroyer Deity: With the exception of Matador and Hell Biker, all of them are associated with The End of the World as We Know It. White Rider, Red Rider, Black Rider, Pale Rider are the Horsemen of the Apocalypse. Mother Harlot and Trumpeter are from the Book of Revelation. And some Buddhist traditions similarly say Sokushinbutsu like Daisoujou will return during the end of days.
- Dem Bones: All of them, excluding the Demi-Fiend and Dante/Raidou, are skeletons.
- Giant Space Flea from Nowhere: Aside from some Five-Second Foreshadowing with a manikin mentioning the Grim Reaper, Matador comes from nowhere in comparison to the rest of the fiends (who are at least mentioned as being drawn to the Demi-Fiend via the Menorahs).
- Horsemen of the Apocalypse: White Rider, Red Rider, Black Rider, Pale Rider are the literal bringers of Conquest, War, Famine and Death at the end of the world.
- Large Ham: Each of the Fiends have hammy introductions and speeches. Some, such as Matador and Hell Biker, more than others.
- Leitmotif: All share the cutscene theme "TALK" and battle theme "Fiend".
- Nintendo Hard: The Fiends are generally considered the hardest bosses in the game. More or less justified as Lucifer is trying to test if you're strong enough to aid him.
- Puzzle Boss: Trumpeter is perhaps the most puzzling boss in the game, save for maybe Ongyo-Ki and Noah. He requires you to manage you and your demons' HP levels while counting the amount of turns going by in order to avoid Trumpeter fully healing himself or the Demi-fiend being one hit killed.
- Signature Move: All the Fiends have at least one.
- Matador has Red Capote and Andalucia.
- Daisoujou has Preach and Meditation.
- Hell Biker has Hell Spin, Hell Burner, and Hell Exhaust.
- White Rider has God's Bow.
- Red Rider has Terrorblade.
- Black Rider has Soul Divide.
- Pale Rider has Pestilence.
- Mother Harlot has Beast Roar and Death Lust.
- Trumpeter has Evil Melody and Holy Melody.
- Wake-Up Call Boss: Matador is one of the most infamous examples in the history of JRPGs. He will always start off the battle using Red Capote, maximizing his Agility and causing most attacks to miss him, costing Press Turns while he uses party-wide attacks like Mazan and Andalucia.
Wicked King (Beelzebub)
The master of the Fourth Kalpa and second in command to Lucifer. He is the one responsible for the Cursed Areas in the Labyrinth. His true identity is Beelzebub, the Lord of the Flies.
- Big Creepy-Crawlies: His true form resembles a giant fly.
- Bonus Boss: He's the boss of the Fourth Kalpa, so in all endings save for the True Demon Ending, you can avoid fighting him.
- The Dragon: He's Lucifer's number two.
- Leitmotif: Has both the SMT 1 Chaos theme and a unique battle theme.
- Signature Move: Death Flies, a Death/Almighty move that one hit kills anything not immune to Death and does Almighty damage if someone is immune.
Noble Voice (Metatron)
Voiced by: Patrick Seitz (English)
A mysterious voice that calls to the Demi-fiend in the Second Kalpa, ordering him to leave the Labyrinth. In the Fifth Kalpa, he declares the Demi-fiend to be tainted with darkness and attacks him, revealing himself as Metatron and serving as the final boss of the Labyrinth of Amala.
- Bonus Boss: Similarly to the Wicked King.
- The Dragon: As the voice of the Great Will, he's this for the Labyrinth of Amala sidequest.
- Leitmotif: As the Law counterpart to the Wicked King, he gets the SMT 1 Law theme along with his own battle theme.
- Light Is Not Good: He's an Angel of God, and he will kick your ass.
- Signature Move: Fire of Sinai, a powerful Almighty move that can hit everyone multiple times.
- You Shall Not Pass!: He's fighting you to stop you from meeting Lucifer at the bottom of the Labyrinth.

The mysterious, sentient sun that eternally casts its light over the Vortex World. The Vortex World's denizens measure the time based on the brightness of Kagutsuchi, which is measured in a continuous eight-stage cycle. According to legend, once the Vortex World's Reasons have been assembled, their leaders must ascend to Kagutsuchi itself in order to determine which Reason will become the basis of the new world. It is actually an avatar of the Great Will, which he created to oversee the cycle of destruction and recreation of worlds that do not meet his ridiculously skewed standards, with the ultimate goal of eventually creating a world that is fully subservient to the Great Will.
- Achilles' Heel: The Kagutsuchi phase will permanently turn to "bright" in the second half of the fight, meaning any demons equipped with the Bright Might skill will score automatic critical hits with all their regular attacks.
- Affably Evil: If you come to it representing any of the Reasons, it isn't hostile towards you at all and only fights you to test your resolve to create the new world. In fact, when you first meet him immediately after the Conception happens, he encourages you to go find a Reason.
- Deader Than Dead: In the True Demon Ending the Demi-fiend doesn't just kill it, he precludes it from existing in any world ever again.
- The Evils of Free Will: It fully believes in this.
- Elemental Powers: Uses all four elements during both fights.
- Final Boss: Of all routes save the regular Demon Ending, where he pulls No Final Boss for You out of disgust.
- Knight Templar: It acts as the main representative for the Great Will in the main game, though Kagutsuchi's far from the only villain.
- Late-Arrival Spoiler: DLC in Apocalypse heavily hints at his Final Boss status, with the Demi-fiend referencing how he beat Kagutsuchi.
- Light 'em Up: Being as it's a great ball of living, omnipotent light, it's only natural that it employs light as a weapon. Of note is its Infinite Light attack, where it unleashes a massive beam upon the party.
- Light Is Not Good: As a combination of the Sun, Moon, and God, he's obviously associated with light. He's also one of the villains.
- No Final Boss for You: If you complete the game without siding with any Reason, it dismisses the Demi-Fiend for leaving the world in ruin.
- Screw This, I'm Outta Here!: In the Demon ending.
- Sequential Boss: One in the form he's in throughout the game, then a second form as a giant face.
- That's No Moon!: Though it does act as one for a similar moon phase system during the game.
- Trick Boss: While still technically the Final Boss for the True Demon Ending, there's a True Final Boss immediately following.
- Villainous Breakdown: It does not take kindly to the Demi-fiend choosing Freedom, Demon, or True Demon and in two of those endings attacks him out of rage.
- Walking Spoiler: Most of the tropes listed here are heavy spoilers for the end-game and his boss fight.
- Wave-Motion Gun: His signature Infinite Light skill. In terms of raw damage output, it's one of the strongest attacks in the game, capable of hitting around 1400 to 1800 damage unmitigated. Considering that the maximum Cap for party member HP in this game is 999...
The Blond Child/The Old Gentleman/Lucifer
Blond Child voiced by: Mariya Ise (Japanese), Sarah Williams (English)
Old Gentleman voiced by: Shin-ichiro Miki (Japanese), Paul Eiding (English)
Two mysterious people that seem to be connected to one another. The Blond Child appears prior to the Conception in the basement of the Hospital before the protagonist, accompanied by an old woman in black. After the Conception, the blonde boy drops a Magatama in the protagonist's eye, causing him to turn into the Demi-fiend.
The Old Gentleman is a wheelchair-bound blond old man who also appears throughout the story, accompanied by a young woman in black, and seems to be related to the Blond Child.
Both are eventually revealed to be forms of Lucifer, guiding the protagonist from the shadows.
- Achilles' Heel: Part of why many swear by making the Demi-Fiend a Physical Powerhouse is the Pierce passive your first Magatama can give you, which gets unlocked when you complete the Labyrinth of Amala. It's the only thing that can bypass his resistances, and that will allow you to take him down within a decent timescale.
- Affably Evil: Neither of them are particularly aggressive towards you. Even should you pick paths they will not agree with, they will do nothing to stop you. The only point you can fight their true form is when you ally with him.
- Ambiguous Situation: After beating him in the True Demon Ending, does he make the Demi-fiend the leader of his army, and thus his right-hand man, or does he step down on his role as Demon King, and hands the title and power over to him? It's never fully clarified.
- Ascended Extra: In the original, non-Maniax Japanese release, they didn't do much in the plot beyond give the protagonist the Magatama and subtly guiding them along. In the Maniax, Chronicles, and International versions, their role was significantly expanded.
- Attack of the 50-Foot Whatever: Lucifer is by far THE biggest enemy in the game, rivaled only by Kagutsuchi.
- The Chooser of The One: The Blond Child, and by extension Lucifer chooses the protagonist by giving him the Magatama he needs to survive in the Vortex World. However, he doesn't actually force you to ally with him, merely giving you incentives and letting you choose your path out of your own free will.
- Evil Overlord: Lucifer, altough Affably Evil, is still the ruler of demons, and leader of the Chaos faction. Fittingly, his in-game race in Japanese is Dai Maō, meaning Great Demon King, though it's shortened to the much simpler Devil in English.
- Face of an Angel, Mind of a Demon: The Blond Child appears almost doll-like, but being a form of Lucifer automatically makes him this trope, in the most literal sense possible.
- The Faceless: The Lady in Black wears a dark veil in both her forms that obscures her face entirely, though her younger version does show enough of the lower half to imply she's likely very pretty under it.
- Fascinating Eyebrow: Whenever you attack him in his boss fight, Lucifer will raise his eyebrow, as if to say "Wait, that was supposed to hurt?"
- Fisher Kingdom: A localized version, with the age of Lucifer's human form being directly proportional to the world he currently inhabits. Thus, in the brand new Vortex World, he appears as a child. And in the Time Abyss that is the Labyrinth of Amala, he appears as an exceptionally old gentleman.
- An Ice Person: Lucifer's main elemental spells are ice-based. Makes sense, considering his punishment in the Divine Comedy.
- Identity Impersonator: Zigzagged. The Lady in Black who accompanies the Old Man in the Wheelchair bears a slight resemblance to Yuko, the Demi-fiend's teacher and the two even share the same voice actor in the HD Remaster, sometimes speaking certain phrases that would imply she's his teacher, although she never once claims to be Yuko herself. This is likely done to make the Demi-fiend lower his guard and more likely to accept her requests.
- Marathon Boss: Lucifer has the single highest HP amount in the game, even slightly beating out Kagutsuchi's both phases combined. On top of that, he passively reduces ALL damage to an absurd degree, be it physical, elemental, or even Almighty. The only way to get past it is by using the Passive skill Pierce, and even that only works for physical attacks. Easy to say, even with Pierce, the fight can go for a long while. Taken Up to Eleven in the Hard Mode of the Japan-exclusive Chronicles version, in which on top of all of that, Lucifer is scripted to automatically use Diarahan and fully heal himself after losing 40,000 HP (out of 65,535), making his effective max hp 105,535. Thankfully, he only does it once.
- Mouth of Sauron: The Old/Young Lady In Black are the ones who talk in their masters' stead, especially for the Blond Child, whose dialogue is always first 'whispered' to the Old Lady In Black, and then referred to the protagonist. Both the Blond Child and the Old Gentleman only ever speak to you directly in the True Demon Ending.
- New Era Speech: During the True Demon Ending:Lucifer: All of you who lurked in darkness and waited faithfully for this day, hear me. A new demon of darkness has been born...The time has come. Together, let us march forward! To the final battle...where the true enemy lies!
- Pet the Dog: In the Freedom Ending, he will encourage the protagonist to stay strong in the days ahead, for like Lucifer, he chose to follow his own will and has thus made himself an enemy of God.
- Signature Attack: As Lucifer:
- High King: An Almighty attack with a very high chance to Bind all party members.
- Root Of Evil: An attack that causes random effects on all party members, ranging from reducing HP by a percentage to inflicting status ailments. In the Hard mode of the Chronicles edition, it also doubles as a free Dekaja, removing all buffs from your party.
- Spanner in the Works: Lucifer serves as this towards Kagutsuchi/The Great Will. Initially, the Demi-fiend wasn't even meant to become the Demi-fiend, rather he was meant to become another Reason bearer. However, after turning the Demi-fiend into a demon, the Demi-fiend becomes unable to form a Reason and thus either has to back one of the other Reasons or destroy the Vortex World.
- Suddenly Speaking: Both the Blonde Child and the Old Gentleman speak right before the true final boss fight in the True Demon Ending.
- Suspiciously Similar Substitute: Though her identity is never explained, as a woman in a black dress suit with black hair, black stockings and dark red lipstick who serves as Lucifer's right hand, The Lady in Black shares a whole lot of traits with Yuriko / the original Lilith from Shin Megami Tensei I.
- True Final Boss: Their true form, Lucifer, acts as the final boss of the True Demon Ending.
- The Unfought: In the original vanilla version of the game, you never get a chance to battle him.
- The Unreveal: Who or what the Old and Young Lady In Black is is never explained. That having been said, she also shares a lot of design and role similarities to Yuriko / the original Lilith from Shin Megami Tensei I.
- The Watcher: They don't take an active role in the story, preferring to just watch how events unfold after transforming the protagonist into the Demi-Fiend.
- Greater-Scope Villain: The Great Will is the reason why the Conceptions happen in the first place. Kagutsuchi is merely an extension of its will, and all the holders of Reasons are pawns in its cosmic design.
- God Is Evil: The world(s) being stuck in a cycle of destruction and rebirth is due to the Great Will's cosmic planning. Even if you ignore the immense amount of death and suffering it causes, it basically sending Hijiri to eternal damnation for an unknown 'ultimate sin' and its servants' Knight Templar attitude does not portray them in the most positive of lights.
- The Unfought: While it's heavily implied the Demi-fiend and his army of demons march to fight it at the end of the True Demon Ending, the credits roll before the player gets a chance to see the fight itself or the aftermath.
- The Voice: Barely. The Great Will never actually appears, but it's implied that the very last line in the True Demon Ending is spoken by them, the only time they ever interact in the game:You have created a demon in your heart's likeness, fallen angel? Then, doom shall set us apart...now and forevermore.
