Humans and Manikins
The protagonist of Nocturne. His human name is up to the player.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.Depending on which Reason he supports, he can create one of three new worlds at the end of the game. He can also choose to reject the laws of the Vortex World, returning the world to normal, keeping the world trapped as the Vortex World for eternity, or becoming a full demon and destroying the cycle of death and rebirth itself.
- 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 do.
- 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 Antichrist: The True Demon Ending has you become this.
- Badass: And how!
- More specifically, If you've go for the True Demon ending, by the end of the game, you fight Lucifer, and depending on your interpretation, you've become his Dragon. Lucifer's plan was to create a new demon who agreed with his chaotic philosophy. He gives you plenty of time to consider alternatives and the Lady in Black explains that you will bring an end to the eternal war between Light and Darkness as the Paragon of Chaos.
- Badass Boast: In Digital Devil Saga, one is left behind after his defeat written on the floorDeath's vastness holds no peace. I come at the end of the long road. Neither human, nor devil... all bends to my will.
- 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.
- 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.
- Bonus Boss: In Digital Devil Saga and Shin Megami Tensei IMAGINE.
- Canon Name: Naoki Kashima, which was used as his name in the Audio Novels. Also called Shin Managi in the novel adaption, Konton.
- The Champion: For Lucifer and Chaos in the True Demon Ending.
- Chosen One: And this time, it isn't much of a revelation.
- 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.
- 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.
- Half-Human Hybrid
- 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.
- Meaningful Name: Explained by the game creators, Hito-Shura means one who bears demonic skin with human heart. Demi-Fiend comes to be a proper adaptation.
- The original, Hitoshura (人修羅) means "human shura," with a shura being a Hindu deity most commonly associated with war and violence.
- 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.
- Not So Different: Is compared to Lucifer in the Freedom ending by Kagutsuchi and Lucifer.
- 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.
- 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.
- Power Tattoo: Inverted, as his tattoos are a by-product of his power 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.
- 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.
- ‹bermensch: Demi-fiend's journey, choices, and endings are thematically similar to Friedrich Nietzsche's concept of the Ubermensch. The use of Zoroastrian deities, the harrowing journey, and the TDE's implication of the Demi-fiend surpassing God seem to be influenced by Nietzsche's philosophy. The Demi-fiend, therefore, is one of the most positive and accurate representations of the Ubermensch in gaming, art, and possibly the only positive representation since most other depictions misrepresent the concept to be synonymous with evil.
- Unwitting Pawn: 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.
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.As the Maiden of the Vortex World, she expected to be the cornerstone of a world of freedom, but finds herself betrayed by Hikawa and used as a mere tool in his quest for a world of stillness. Her failing is a 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.She is eventually possessed by a "goddess" from another dimension called Aradia. She continues to rely on Aradia, expecting to be given a Reason and not realizing that Aradia is incapable of doing so. In the end, Yuko fails to create her own Reason and is sacrificed by Hikawa to bring his own Reason to fruition.
- 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.
- Demonic Possession: By Aradia.
- Flat Character: This is her main character flaw and as a result she get's 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.
- 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.
- 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.
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.She is heavily traumatized by her weakness at the hands of the demonic populace, being thrust from a world where she always got her own way to one where she is powerless and abused. The result is the Reason of Yosuga: a world without a lower class for her to fall to, where the weak elements of society are ruthlessly purged and the strong reign supreme.
- 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.
- An Arm and a Leg meeting and trying to fight Sakahagi over magatsuhi ends with her getting her right arm cut off.
- Break the Cutie: She's genuinely scared/much, much nicer during the start of the game, but then having find her Reason and getting her right arm blasted away, added with the pressure the Vortex World give to her really do the job.
- Didn't Think This Through: Her philosophy at first glance is might makes right. Which falls apart when you realize that as long as there are two beings; there is one that will be weak and one that will be strong. The stronger always winning, so the weak is cast out. Chiaki doesn't seem to realize that eventually someone can challenge and kill her; making her victim to her own philosophy.
- With this said,right before her battle in the Yosuga route, she seems to have acknowledged this facet of her philosophy,which is why she even fights you. She is also surprisingly accepting of her death, should you beat her in her route.
- Dub Name Change: Her last name is changed because of character limits.
- Evil Cannot Comprehend Good: After being defeated she fails to comprehend why someone strong wouldn't want a darwinist world.
- Mystical White Hair: Chiaki becomes this when absorbing Gozu-Tennoh's power. Also a case of White Hair, Black Heart.
- Red Right Hand: She gains tendrils to replace the arm that she lost to Sakahagi.
- Social Darwinist: The massacre of the Manikins for being weak and useless. Oddly enough, the Amala Labyrinth sidequest regarding the Manikins reveals that Chiaki was right. They're just the last remnants of the old world that will perish once the new world is created.
- Supernatural Gold Eyes: After she gains her demon form.
- There Can Be Only One: She challenges you after beating the rest of the Reason bosses, stating that only one of them can lead the new world.
- Unlucky Childhood Friend: According to Isamu in the Drama CD, she and Naoki had a very close relationship, and probably would have start a romantic relationship if not for the Conception. YMMV whether it was subverted or not in the Freedom ending.
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.He fails to find Yuko and loses all faith in other people, severing all ties to his friends and drawing upon himself for comfort and strength. He resolves to create a world where the Self is absolute, and no-one can interfere with anyone else, thus creating the Reason of Musubi.
- 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.
- Hypocrite: 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. 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.
- Stopped Caring: After being beaten.
- Student Teacher Romance: Seems to have an unrequited crush on Ms. Takao.
- Walking Shirtless Scene: After absorbing souls in the Amala Network... though considering what's underneath, you'd probably wish he wasn't.
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.Hikawa is a mysterious man because he deliberately stays underneath the radar. He was able to hold a powerful position in a prominent communications company without leaking a hint as to his true belief. After the Conception occurs, many believe it to have been the work of the ancient Assembly of Nihilo; no-one suspects that it was actually Hikawa.He is a man devoted to the Reason of Shijima from the very beginning and acts accordingly. Every move he makes is calm and calculated as he swiftly moves his way towards realizing his vision of a new world. But also like Shijima, he is utterly emotionless in his actions, using Yuko as his pawn and destroying all resistance with no hesitation and minimal effort. It is all in an effort to shape the world in a fashion where conflict doesn't exist.Ironically, while Hikawa works towards a world without emotions or free will, he himself is a very passionate and independent ‹bermensch, breaking with the Gaea Cult because he wouldn't follow the Gaea Cult's doctrine, and causing the Conception out of his own moral sensibilities. Ultimately, Hikawa could not live in a Shijima world, as his own passion would be incompatible with the rest of humanity.
- 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: Initially.
- It's Quiet... Too Quiet: After being defeated, he realizes the stillness has come for him.
- Puzzle Boss: As Ahriman.
- World of Silence: What he hopes to achieve.
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.Soon, knowledge becomes everything to him, from him disregarding the worth of human life in the Vortex World to bribing the Demi-Fiend with the facts that he has discovered through the Amala Terminals. With knowledge comes power, and with power comes corruption. However, Hijiri does not seem to realize that he could create a new world until he learns this information through the Amala Terminal. It is also notable that he never mentions the dream that the Demi-Fiend, Chiaki and Isamu all share upon entering the Vortex World.Ends up being sacrificed by Isamu in order to summon Noah.Completing the optional Fourth Kalpa dungeon reveals that Hijiri actually died when the Conception occurred, having failed to reach the hospital in time. However, he continues to exist in the Vortex World as his punishment for committing the "ultimate sin". Hijiri's punishment is to be trapped in an endless cycle of suffering, death and rebirth, being forced to witness the creation and destruction of each world without having any chance to affect the outcome.
- 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.
- Fate Worse Than Death: He's required to observe and record the events of each new world, but is never allowed to affect them.
- Intrepid Reporter: He was a journalist pre-Conception, but keeps investigating the world after it takes place.
- Nice Hat: It doesn't get a Memetic Mutation status like Isamu's, though.
FutomimiThe leader of the Manikins. He has the ability to tell the immediate future. After he and the other Manikins imprisoned in Mizuchi's mirage had been freed, Futomimi was grateful to the Demi-Fiend.His visions led the Manikins in their path to find their Reason, wishing to make a world full of Manikins where they were no longer just slaves (or worthless mud dolls as Chiaki liked to claim), starting with the exodus that led to the creation of their village in Asakusa, with him meditating in seclusion in their holy land, Mifunashiro. His defeat at the hands of Chiaki (or the Demi-Fiend if he chose to align with Yosuga) left the Manikins without hope, left to watch the new world's birth with no way to control it. Justified, as the Afterlife Bell Quest firmly points out that Manikins are just remnant emotions of the Old World and that they cannot conceive a Reason. Futomimi's actions would have meant more bloodshed if allowed because he only wanted a world of Manikins.Futomimi is to be later reborn, called back into the Vortex World by the Afterlife Bell. His imprisoned spirit as a wild and rebellious but depressed yanki in the previous life can be liberated from the Maze of Hell in the 4th Kalpa of the Labyrinth of Amala. He will gain new powers and will become part of the Kishin clan, able to be summoned in the Cathedral Of Shadows as the Demi-Fiend's minion.An interesting attribute of Futomimi is that he is the only Manikin that does not have constant involuntary spasms. This may be because he was born from a single person's emotions (as opposed to other Manikins, who were born from many different people's emotions).
- 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.
- Shoot the Shaggy Dog: His efforts to lead the Manikin are fruitless, since they can't conceive a Reason to build the new world.
SakahagiA 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.Sakahagi is to be later reborn, called back into the Vortex World by the Afterlife Bell. His imprisoned spirit as a formerly successful businessman in the previous life can be liberated from the Maze of Hell in the 4th Kalpa of the Labyrinth of Amala. He will gain new powers and will become part of the Foul clan, able to be summoned in the Cathedral Of Shadows as the Demi-Fiend's minion.
- 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 as 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: Girimehkala.
- 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.
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.Somehow he's found his way into the Vortex World by mysterious means. He often appears to the Demi-fiend to challenge him to battle (he's classified as a Fiend and thus is in possession of a candelabra needed to advance deeper into the Kalpas). Of course, it turns out he's most definitely not on Lucifer's side. If the Demi-fiend manages to enter the Fifth Kalpa, Dante will offer to join up with him... and won't budge until you say yes. Dante will then flip a coin—if it's heads, you'll only have to pay him 1 Macca to hire him. If tails, then he will take half of your Macca. (It's always heads, due to it being a double-sided coin.) When all is said and done, Dante will join your party's ranks, regardless of Demi-fiend's alignment or level.In Chronicle Edition Dante is replaced by Raidou Kuzunoha the 14th.
- Awesome, but Impractical: He cannot learn Pierce, so he's not all that great to use 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.
- Bad Ass: This is Dante we're talking about.
- 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.
- Defeat Means Friendship: After you beat him in the Third Kalpa he'll join you in the Fifth.
- Demon Slaying: His profession.
- 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.
- Non-Elemental: His Stinger and Show Time skills do Almighty damage.
- No Sell: He's one of the very rare party members that's 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.
- 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.
Raidou Kuzunoha the 14th
Dante's replacement in the Japan-only release, Chronicle Edition.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. He also can gain the ability "Pierce", a skill unavailable to Dante.
- 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.
- Heroic Mime: He never speaks himself, relying on Gouto to speak for him.
- Non-Human Sidekick: Gouto, who is a talking cat.
- Suspiciously Similar Substitute: His skills are largely just renames of Dante's.
- 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: But of course.
- Evil Makeover: He becomes Black Frost.
- Optional Party Member: Shows up in the Amala Labyrinth after being defeated, ready to join you.
- Scratch Damage: Takes only 10% damage from physical attacks as a boss. Strangely enough, he keeps this attribute when he joins you.
- Verbal Tic: Like most Jacks, he tends to inject "Hee ho!".
KagutsuchiThe 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.
- Big Bad: Acts as the main representative for the Great Will in the main game, though Kagutsuchi's far from the only villain.
- 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: 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.
- 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.
- 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.
SamaelOne 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.
- 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.
- Standard Status Effects: His attack God's Curse can inflict different status effects onto his enemies.
- Status Buff: Tends to Rakukaja a lot during his fight.
- The Dragon: Literally one to Hikawa and should you side with Shijima he'll become your dragon.
ThorGozu-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.
- Establishing Character Moment: His aforementioned beating-up of Isamu. To further establish his character, he throws you into prison as well.
- Judge, Jury, and Executioner: The Mantra Army Court he presides.
- Shock and Awe: It's Thor, what do you expect?
- Status Buff: Uses Tarukaja to boost his attack.
- The Dragon: To Gozu-Tennoh and later Chiaki, sorta.
- Villain Forgot to Level Grind: Sorta. While he does get new tricks from his first fight with you, by the time you fight him again, you'll probably be far too powerful and he'll end up being a BreatherBoss.
- Win Your Freedom: Sure. He can respect ya. Just prove you're not a wimp.
The FiendsA group of demons that the Demi-Fiend can encounter at various points in the game. They all hold a Candelabrum 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, Dante, Daisoujou, Hell Biker, White Rider, Red Rider, Black Rider, Pale Rider, Mother Harlot, and Trumpeter.Completing the Labyrinth of Amala will reveal their true purpose: they are a test created by Lucifer in order to find a demon who is powerful enough to be his right-hand man in defeating The Great Will. By defeating all the demons and obtaining all their candelabra, the Demi-Fiend proves that he has the potential to aid Lucifer in his ultimate goal. This will seal the path the Demi-Fiend takes: the True Demon Ending.For Dante, see the Humans and Manikins folder.
- 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 and Dante's first fight none of the Fiends are required to beat the game unless you want the True Demon Ending.
- Large Ham: Each of the Fiends have hammy introductions and speeches. Some, such as Matador and Hell Biker, more than others.
- Leitmotif: All of them except Dante share a pre-battle and battle theme.
- 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.
- Dante's entire kit.
- 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.
- 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. Newbies always have a hard time against him...until they realize they can counter Red Capote by utilizing Sukukaja, Sukunda, and Fog Breath, as well as cause him to lose Press Turns by bringing along a demon that nullifies Force. He can still nullify your debuffs by just using Dekunda and/or using Red Capote again, but doing so makes the fight much more bearable.
Wicked King BeelzebubThe 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.
