The Hero

The Hero (AKA Kazuya Minegishi)

Voiced by: Takahiro Mizushima (Drama CD), Miyu Irino (Overclocked)

A blue-haired seventeen-year-old who always wears a distinctive set of headphones. His given name, surname, and nickname are decided by the player, except in the manga adaptation, where he is named Kazuya Minegishi. All of his stat development and how he ultimately handles the chaos around him are determined by the player.

---

• Abdicate the Throne: In Atsuro's route, he hands the power of Babel over to the government. In Gin's/Haru's route, he rejects the throne of Bel altogether, ordering Babel back to the demon world forever so that no one can have ever ascend the throne again.
• An Adventurer Is You: His parameters are based on what the player chooses to increase upon leveling up, leaving him to be able to take on any role the player wants him to.
• All-Loving Hero: Depending on your choices, he may prove to be this, such as in Amane's 8th Day, where it's noted that he's willing to forgive Cain/Naoya where the original Abel never would have.
• Animal Motifs: Because of his headphones, he resembles a cat.
• The Antichrist: Depending on your choices in "The King's Decision" 8th Day in Overclocked, he could end up being this in the Evil King of Demons ending, or Anti-Anti-Christ in the Good King of Demons ending.
• Anti-Villain: In the Evil King of Demons ending, where he does evil to save humanity from annihilation by leading the demons against God, but will also kill anyone who stands in their way.
• Aside Glance: His smiling portrait appears to be looking at the player, and he usually switches to it upon making certain dialogue choices, as if to tell the player, "Nice one."
• Badass Adorable: Due to the art style, he looks like one in Amane's and Naoya's endings.
• Badass Boast: During Naoya's 8th Day, to Metatron. Doubles as a Blasphemous Boast:
  "God's reign ends today."
• Badass Cape: Is shown to be wearing either a white or black cape in some of the endings and is quite imposing in both.
• Beware the Nice Ones: Depending on your dialogue options, he can be presented as a rather friendly and charismatic young man who provides much-needed moral support to his comrades, to the point that he can even become a Messiah for this. He is also a One-Man Army who can take on several demonic entities and deities and WIN, thus making it highly imperative that you don't piss him off.
• Blood Knight: Player choice. He can be rather eager to seek out and fight demons that most people would be nervous about challenging at best. In fact, given that most of the best endings require you to fight for the Throne of Bel, it's even preferable to play him this way.
• Brought Down to Normal: Subverted. In Gin/Haru's ending, despite having effectively given up becoming the King of Bel and sending Babel back into the demon world, an e-mail from Metatron warns him he still has all the powers he gained from killing the other Bels and said power is merely "slumbering". If the protagonist isn't careful, Metatron states he and the rest of Heaven will come to kill him should he ever lose control or give into his powers.
• But Now I Must Go:
  • In Naoya's Good 8th Day, he leaves for the demon world to raise an army to overthrow God, but he vows to return once he is finished with his war. Naoya watches over his progress, and Atsuro and Yuzu faithfully wait for his return. By all indications, he seems well on his way to fulfilling the promise by the time of the epilogue.
  • In Amane's 8th Day, he leaves to travel the world to continue spreading God's influence through defeating other gods like Okuninushi.
  • In the manga adaptation, he heads to the demon world to make good and damn sure that the power of Bel is sealed away. He's back in a month, though.
• Cain and Abel: Abel to his cousin Naoya's Cain but subverted in that Naoya doesn't want to hurt him unless you choose to take certain routes. It turns out to be quite literal, as he is Abel's reincarnation. Taking Naoya's route makes him the Cain to Metatron's Abel during the 8th day. Two descendants of Adam, Enoch, who became Metatron, and Abel, who became the Lord of Bel, facing off against one another in the final battle.
• The Call Knows Where You Live: The adventure begins when a demon kills someone in your cousin's apartment complex, and you get jumped by demons a little while later.
• Chaste Hero: You can definitely play him out to be this. For example, when Kaido asks him if Yuzu is his girlfriend, you have one of three options; if you choose "She's just a friend.", Kaido calls you out on it.
  Kaido: Are you that friggin' dense?
• Chick Magnet: Yuzu and Amane fall for the protagonist. Haru flirts with him. In the manga, Yuzu's classmates are jealous of her having Kazuya as a childhood friend.
• Cincinnatus: Can be played this way, only participating in the battle for the Throne of Bel because it's the party's best shot at getting rid of the demons and because basically everyone, even the Token Good Angel, pushes him in that role. In one route, his first and last act as King of Bel is to send Babel back to Hell and return things to normal. Technically, he still holds the title of King of Bel afterward, but he basically abdicated his power right there and then.
• Cloudcuckoolander: The tone of his dialogue choices tend to be when not they are not savvy, a Badass Boast, or Obfuscating Stupidity.
  Naoya: ...Your thought process never ceases to amaze me.
• Dark Is Not Evil: Can be played as this depending on your choices. Despite becoming the almighty lord of demons in Naoya's route and being expected to use his power to subjugate humanity, he can instead choose to use his newfound abilities to fight for mankind as a whole and unite them together against the angels' tyranny.
• Dark Messiah: In the Law and Chaos routes. Subverted in both of the 8th Days; in the Law route, he becomes an actual Messiah and would rather try to coax a sinner into atoning rather than outright killing them. In the Chaos route, he also becomes something of a Messiah as he can choose not to kill any humans and protect them from the angels — the people, in turn, will side with him and unite to fight against angels.
• Deadpan Snarker: Some of his dialogue options can get pretty snarky.
• Did You Just Flip Off Cthulhu?: Some of his dialogue options against certain enemies and bosses definitely ring of this. And if the player is good enough, he can back up his insults as well.
• Even Evil Has Standards:
  • The overlord route can be this, provided you don't kill the humans attacking at the angels' urging.
  • If you're on the inhuman 8th Day, you kill the generic tamers but will not kill Yuzu and Midori.
• Fallen Hero: Can potentially become this, transforming from a heroic young man who goes out of his way to help others in need into a demonic tyrant who won't hesitate to kill anyone that stands in his way.
• Fighting Your Friend: Multiple times throughout the game, depending on your actions. You can potentially see yourself going from fighting alongside your allies to fighting against them, such is the case with Yuzu and Midori on the inhuman 8th Day.
• From Nobody to Nightmare: While anyone with a COMP can potentially become this trope provided they survive making a demon contract, the MC, in particular, stands out due to him facing off against several demon overlords bent on winning a battle royale to become the ultimate ruler of all demons and which he himself can win, doing so to become the next Demon King or Messiah. He even fights and defeats Lucifer as a Superboss. In Overclocked, one of the 8th Days (Demon King Route) has you fight Metatron as the Final Boss, with the ending making it clear that the next enemy is the Big Man Himself!
• Fully-Embraced Fiend: Can be played as this on Naoya's 8th Day. Having finally awoken his power as the new King of Bel, the player can now decide to completely abandon their human morality and slaughter everyone opposing them, giving in to their demonic soul and ultimately ending with taking over the world.
• Headphones Equal Isolation: Subverted, since he tends toward Magnetic Hero. He can be played more or less straight by player choices, however.
• The Heart: Helps keep the party and their mental states in check and can even take time out of his schedule to comfort them about their issues and provide a supportive hand.
• Heroic Mime: At least he gets a lot of lines, even if you choose everything he says. In addition, if the Hero is your only party member on the field, all in-game conversations will begin and end with him. This includes things that Atsuro would typically do, like threatening thugs and reassuring civilians, but he also gains some neat one-liners.
• Hypocrite: If you previously fought Keisuke to stop his twisted idea of justice (read: he was killing anyone that he thought was unjust) or you stopped Honda from escaping the blockade, the MC can become this if the Messiah or Escape endings are chosen; as the Messiah, he judges sinners (most likely by killing them), and in the Escape ending, he and his friends flee the lockdown. Subverted in Amane's 8th Day however. You begin to save those who are considered irredeemable when you realize the Angels wanted them to die, choosing it as a better option. You even make up with Naoya enough for Okuninushi to decide to leave Japan in your hands and believes that you are the Messiah.
• I Am Who?: Abel.
• It Sucks to Be the Chosen One: For him, being The Chosen One means being fated to fight a series of terrifyingly powerful demons in a contest for power that will make him a target of Heaven and the demons if he goes too far out of line... not to mention being personally responsible for the lives of everybody in the lockdown.
• Kingmaker Scenario: Most of the routes in the game will have you becoming the King of Bel in one way or another, with multiple factions trying their best to get to him in order to direct his newfound power into accomplishing their own goals.
• Lightning Bruiser: If the player focuses on getting his Agility up and builds him up with the right skills, he can become this in higher levels, being capable of launching insane amounts of damage, whether through magic or sheer physical strength.
• Magnetic Hero: Yuzu has a huge crush on him, Midori has been known to trigger Yuzu's jealous outbursts, Amane seems to trust the Hero at first glance, and Haru opens up to him easily (and even "invites" him to hit on her). As for guys, Atsuro sticks with him in every ending path, and Kaido trusts him enough to tell him about his love for Mari and even plot to rule the world with him.
• Many Spirits Inside of One: Upon defeating the Bels, their spirits and essence merge with him. Although, they don't talk to him or try to assert themselves, with them only showing that they are there inside him on the Overlord's Despot 8th Day.
• Medium Awareness: Not a large example, but the Aside Glance he gives tends to be after choosing funny, snarky, or cool dialogue, hinting that he knows there's a player picking his lines for him.
• Meaningful Name: He is a reincarnation of Abel. A Bel.
• My God, What Have I Done?: Heavily implied in the Evil version of Naoya's 8th day after the fight against Yuzu and Midori, especially if you choose the dialogue option that has the Protagonist practically beg Yuzu not to leave and to hear him out.
• Noble Demon: You become this in Naoya's 8th day in Overclocked if you choose to spare the humans who are helping the Angel rebels. Mankind sides with him against God and his Angels during Naoya's Good 8th Day.
• Not Quite Human: In the 8th Days where you become King of Bel, the MC's race has changed to "Bel", even though he still hasn't awakened to his full power and thus is still considered "human" enough.
• Not So Stoic: He's quite capable of getting very angry, however, and can act as The Gadfly to several party members over the course of the game.
• Obfuscating Stupidity:
  • Most of the dialogue options are a choice between stupid and savvy, and, given the presence of the latter, one gets the impression the stupid answers are simply the protagonist playing dumb. If you pick a specific "stupid" response during Naoya's ending, he'll even call the MC out on it.
  • Given the Protagonist's perceptiveness throughout the game, it's heavily implied that he is perfectly aware of Yuzu's feelings and feels that a lockdown that may well lead to the End of the World as We Know It isn't the best time to get involved in a romance.
• Oblivious to Love: Possibly, if you deny that Yuzu is your girlfriend when Kaido asks about it. He'll call you dense in response for not noticing how Yuzu apparently stares at you all the time.
• Only I Can Kill Him: He's the one who gains possession of the Devil's Fuge, and, as such, is the only character in the game capable of damaging Beldr. This also means that during the Day 3 Beldr fight, if he bites it, it's game over, and if he dies during the Day 7 rematch without anyone able to revive him, the battle is Unwinnable by Design (as it lacks the "player character dies" defeat condition of the first fight).
• Order Versus Chaos: Can be played any which way, as he is the player character.
• Oxymoronic Being: Depending on your choices, he can become this. In Amane's route, he can pursue power to become the King of Bel, a nigh-powerful being who ruled over the demons and fought God himself to become the Messiah and directly serve under God.
• The Paragon:
  • As the Messiah, he can become this, as his various good deeds and genuine desire to redeem sinners can cause some of the most die-hard degenerates of society to truly reflect on their actions and try to atone for their sins.
  • He can even become this as the Overlord as well, as it's due to his refusal to harm innocent people in his war against God and Chronic Hero Syndrome that humanity learns to put aside their differences and stand up against Metatron and the angels.
• Person of Mass Destruction: He spends the entire game gaining more power and slowly evolving from your average high school student to becoming one of the most powerful beings in existence, capable of taking on multiple demons and deities and even God himself in some of the endings.
• Psychotic Smirk: His usual smile becomes one of these during Naoya's route. Compared to his usual expression throughout the game, it's quite unsettling.
• Red Eyes, Take Warning: Never shown in-game. However, he (along with every other character) sports these on the box art for Overclocked. Fanon also tends to portray him with red eyes when drawing him as the King of Bel, despite not having them even in the King of Demons ending.
• Reincarnation: Of the biblical Abel, with his cousin Naoya serving as the Cain.
• Reluctant Warrior: You have the option of saying this in Naoya's inhuman path of all things.
• Stealth Pun: He is Abel. He defeats the Bels. Therefore, he is a Bel. A Bel.
• The Stoic: The default setting for the Hero, more or less, with many characters coming to rely on him for his steadfast and reliable nature.
• Toxic Friend Influence: On Naoya's evil 8th Day, you drag Atsuro further and further down with you as you decide to conquer the world and kill anyone who opposes you.
• Turn the Other Cheek: In Amane's 8th Day route, he can potentially show mercy to Naoya/Cain for killing him all of those millennia ago and even outright tell him that he forgives him and never hated him to begin with, which is something the original Abel would never be able to do.
• Villain Protagonist: In the 8th day of Naoya's route, you have the choice to actually kill other humans. Doing this will turn you against many of the characters, including some potential party members. Of course, subverted if you choose to kill only angels.
• Villain with Good Publicity: In the evil Naoya 8th Day. Where the masses support him while the people's own governments opposed him.
• Warrior Therapist: Can kick a vast amount of demon ass while simultaneously helping people with their various life problems.
• We Cannot Go On Without You: Since only you have the Devil's Fuge, only you can defeat Beldr. That means if you bite it during his boss battle, it's Game Over.
• Worthy Opponent: Metatron sees him as this in the King of Demons ending. YHVH sees him as this in the Good Naoya 8th Day, which is why they are fighting their war where the earth won't be involved.

Atsuro Kihara

Atsuro Kihara

Voiced by: Atsushi Abe (JP), Spike Spencer (EN)

One of the hero's friends from school, and a computer whiz. Considers himself Naoya's apprentice, and loves all things technological... and explaining them in simple terms for Yuzu's sake. Gets all starry-eyed when excited. While he thinks that the best way to deal with the crisis is figure out how to completely control all the demons, he'll support his friend no matter what he decides.

---

• All Love Is Unrequited: He has feelings for Yuzu who has feelings for the protagonist.
• Awesomeness by Analysis: One of his most useful traits. Not only is he able to figure out several of the COMP’s functions after tinkering with it in a short amount of time but he is also able to readily assess a situation in front of him and help push towards the best solution.
• Badass Bookworm: He's definitely a nerd... who as a Demon Tamer is also a Genius Bruiser given his high physical attack power.
• Became Their Own Antithesis: After learning that Honda's superiors want to research demons for their own uses, is unnerved by the potential abuses. Later on, however, he becomes smitten with the idea of finding a way to completely control all demons and harness their powers for everyone's benefit...
• Beware the Nice Ones: Should Keisuke get killed by Kaido, Atsuro will get absolutely pissed and swear revenge on him.
• Bromantic Foil: To the MC, being the cheerful, passionate nerd to your stoic, coolheaded nature.
• Break the Cutie: If Keisuke is killed, Atsuro becomes despondent, now terrified of the potential misuses of giving demons to humanity, and completely abandons his plan to take control of them.
• Character Select Forcing: He is the only physical tamer you get for the first six days, so unless you yourself specialize in physical moves, it is extremely difficult to take him out of the party. You can't safely replace him until very late in Yuzu's 8th day or the beginning of Naoya's 7th day when Kaido joins you, and in the latter case you're still stuck with him if you miss both Optional Party Members. You can't safely replace him at all in Amane's route (where you never get another physical tamer) or Atsuro and Gin's routes (where he is a Required Party Member for the Final Boss and there is no 8th day).
• Cut Lex Luthor a Check: Atsuro's ending makes it possible to control the demons for the progress of humanity while also evading all the supernatural mumbo jumbo.
• Dump Stat: His other stats are balanced, but his Magic is a little shaky.
• A Friend in Need: Sticks with the hero even after he decides to Rage Against the Heavens and become the demon overlord. He's very reluctant and nervous about it, but in the end he vows to always be by his side.
• Genius Bruiser: A incredibly tech-savvy Badass Bookworm who can dish out insane amounts of damage with his high Strength stat, especially when set up with the right skills.
• Hopeless Suitor: He has feelings for Yuzu... that will go well.
• It Gets Easier: He becomes numb to the violence as you kill enemy demon tamers on Naoya's evil Day 8.
• The Lancer: Will support the hero, no matter what path he takes.
• Lightning Bruiser: He has very high Strength, and slightly lower but still good Vitality and Agility, but because of his low Magic, he can't particularly give or take magical attacks well.
• Mr. Exposition: Particularly when dealing with Yuzu.
• Muggles Do It Better: Downplayed since the magical options work just as well, but his plan is the only way to solve the demon crisis without the protagonist becoming the King of Bel. This is very handy if you let Haru die, meaning you can't fight Belial and become King.
• Nice Guy: A reliable, friendly fellow that does his best to keep the party's spirits up and will never abandon a friend in need.
• The Nicknamer: Likes to call Yuzu by her nickname: Yoohoo. Inverted as well; many people like to come up with nicknames for him, particularly "Otakuro." And later, Jerktsuro in Overclocked.
• Nightmare Fuel Station Attendant: Has a disturbing tendency to speculate about fairly horrifying concepts. Or discover their existence.
• Order Versus Chaos: Despite some misgivings in some routes, he will follow the protagonist to the ends of the Earth. Appropriately, his own route doesn't fit neatly into the SMT spectrum, being a Third Option unique to Devil Survivor.
• Otaku: Yuzu even calls him 'Otakuro' at one point, to his dismay.
• Playful Hacker: A playful gadfly who likes to mess around with his friends and several high-tech databases. He’s so good at this that he’s able to hack into the tower of Babel itself.
• Reed Richards Is Useless: Averted. If you get his ending, Atsuro is able to use Naoya's technology to safely control demons, resulting in Japan becoming a global superpower and gaining a permanent seat in the U.N. Security Council.
• Required Party Member: He's required for several battles. Oddly enough, the first three all take place in situations where you don't actually have enough party members to run afoul of the Arbitrary Headcount Limit, so this only affects a player challenging themselves by limiting their own resources.
  • He's mandatory on the final storyline battle of Day 2 when you have to save his old buddy Keisuke.
  • If you choose to subdue Keisuke and Yama by force, he's required for the ensuing battle.
  • If Kaido kills Keisuke, Atsuro goes on a Roaring Rampage of Revenge and is required for the ensuing fight.
  • For the final battles in Gin's and his own routes, his hacking skills are required to get the demon server to do what you want it to. Overlaps with We Cannot Go On Without You until Babel reveals its true form.
• The Smart Guy: Is usually the one coming up with plans and general strategy on how to stay alive in the lockdown, as well as figuring out the conspiracies behind it and the functions behind the COMP.
• Stepford Smiler: As he admits to the protagonist, he's just as scared as Yuzu over everything that's happened to them in the lockdown but he hides these feelings through humor, light teasing, and a smile in order to not show any weakness around her.
• Take a Third Option: Even if Haru dies, you can still follow Atsuro's route to gain control of demonkind without fighting the Bels.
• Techno Babble: Normally averted; he describes things in layman's terms for Yuzu's sake.
• Techno Wizard: Oh yeah. This saves the the team many times. Depending on your choices, he can even make it so you control demons without becoming the King of Bel and start a Singularity on par with the Industrial Revolution.
• Teen Genius: Successfully navigates through several programming codes and walls that can leave even adults stumped and even hacks into the the tower of Babel.
• These Hands Have Killed: He's the most shocked and dismayed when you first kill enemy humans on Naoya's evil Day 8.
• Token Good Teammate: On Naoya's evil Day 8, he's the only party member to have reservations about how far you're willing to go to oppose God, but sticks around out of personal loyalty to the protagonist.
• Tritagonist: He's the tertiary main character, with whoever your current route's focus character is acting as the deuteragonist (this can be Atsuro himself). He's your most loyal companion, acts as Mr. Exposition and The Smart Guy, and his hacking skills are necessary to save the world in his own and Gin's endings. He's also your only fall-back option if you screw yourself out of becoming the King of Bel by failing to save Haru.
• Undying Loyalty: He is the only playable character who cannot be made to leave the party under any circumstances.
• The Unfought: Due to his never leaving the party, he is one of only two (three in the original version) potential party members who cannot be fought.
• Utopia Justifies the Means: Over time, he grows steadily convinced that the best way to end the lockdown is to hack the server and take complete control of demonkind, using their powers to improve everyone's lives. However, he sticks by you no matter what you decide, unlike others...
• Vitriolic Best Buds: With Yuzu. Even though he tends to tease her a lot and get into arguments with her at times, he does genuinely care about her and will do anything he can to help keep her spirits up.
• We Cannot Go On Without You: In the final battles in the Gin and Atsuro routes, if he bites it before Babel goes One-Winged Angel, it's Game Over.

Yuzu Tanikawa

Yuzu Tanikawa

Voiced by: Ayako Kawasumi (JP), Minori Chihara (drama CD), Melissa Fahn (EN)

The hero's childhood friend, and the girl of the trio. Really not too happy about being caught in the lockdown, and desperately wants to escape. Atsuro calls her 'Yoohoo'; she hates that nickname, but she can't seem to escape that either. Outside of a level of internet-savvy expected from teenagers, she is not very good with computers, allowing Atsuro to explain lots of things for 'her' benefit.

---

• Badass Adorable: She can actually be pretty cute on occasion, what with her crush on the protag and fangirling over Haru and can be quite powerful in battle if set up with the right skills.
• Betty and Veronica: The Betty to Amane's Veronica towards the protagonist's Archie.
• Break the Cutie: Spends the whole week being gradually broken down by all the horror she's experiencing.
• Character Development:
  • Believe it or not, if you DON'T shoot for the Downer Ending, Yuzu quits whining about trying to leave the lockdown and even becomes The Heart of the team to some extent.
  • Even if you go for the Downer Ending, Overclocked gives players an Eighth Day for her ending that allows her to realize her mistake and work to fix it.
• Childhood Friend Romance: She's in love with the protagonist, whom she's known since grade school.
• Clingy Jealous Girl: Gets annoyed whenever any of the other girls show interest in the hero, despite her own insistence that he is not her boyfriend.
• The Complainer Is Always Wrong: See Refusal of the Call. Her (admittedly completely understandable) desire to get the hell out of the lockdown can cause far more problems than it solves.
• Cowardly Lion: Desperate to flee the lockdown and is frequently vocal about it, but is usually the first to suggest jumping into a bad situation to save people, and refuses to abandon anybody in danger. In Overclocked, she will fight the protagonist on Naoya's evil 8th Day, despite having no chance of winning.
• Deadpan Snarker: When it comes to Atsuro and his ramblings.
• Deconstructed Character Archetype: Of the teen heroes typically seen in JRPGs. Yuzu is how a high-schooler with no combat experience would realistically act if suddenly given magical powers and thrown into the apocalypse: she wants nothing to do with any of it and just wants life to go back to normal. She never tries to think of a solution to the whole mess besides "get the hell out of here", and if you take her advice this attitude will doom everyone in the lockdown, and possibly the world.
• Despair Event Horizon: The entire lockdown is one long Break the Cutie moment for her, but she really hits this point at the end of the sixth day. Despite knowing that breaking out of the lockdown will result in the SDF nuking everyone to death, she has a breakdown and begs you to leave anyway, with the rationalization that they wouldn't really do that, would they? Depending on your choices, she either comes back from the brink or drags everything down with her.
• Dirty Coward: Downplayed since it's primarily due to the stress of a week-long Trauma Conga Line catching up with her rather than any intrinsic selfishness on her part. Her ending has you break out of the lockdown, risking causing the government to trigger the final option just to save your own skins. It's downplayed further if you bungle events so badly that there's no way to become King of Bel or hijack the demons through human technology, as at that point there's no legitimate "win condition" left and all you really can do is save yourselves.
• Dual Boss: Her along with Midori if you go for the INHUMAN Naoya path.
• I Will Wait for You: In Naoya's Good 8th Day, after being told by Naoya that it is impossible for humans to follow the protagonist into the demon realm, she tearfully tells the protagonist that she will wait for him to return.
• Jerk with a Heart of Gold: She can be fairly whiny and be quite abrasive towards Atsuro at times but she's also quite willing to help out people in need and refuses to abandon innocent people in danger.
• Leet Lingo: In her e-mails. OH NOEZ!
• Mutually Exclusive Party Members: In the original release, she cannot join on Naoya's route and cannot fight alongside Naoya or Kaido. It's subverted in the 8th Day if you spare the hostile demon tamers, in which case she comes back. Kaido also joins you on her 8th Day, giving you another chance to have them fight alongside each other.
• My God, What Have I Done?: In her ending, being told by Honda that she's helped usher in a world of chaos.
• Nice Job Breaking It, Hero: Her ending. Though her 8th Day scenario allows her to fix things once again.
• Oblivious to Love: Doesn't notice Atsuro has feelings for her.
• Order Versus Chaos: Leans towards neutrality, but will help out on Law (though she may not be entirely happy with the results). Can be convinced to join on the Chaos route if you refuse to kill humans.
• Refusal of the Call: Wants to immediately throw away her COMP, and only hangs onto it to defend herself, longing for a chance to return to ordinary life. That said, she never thinks to leave the group and wait with the other survivors, out of loyalty to her friends. Nobody would blame her, considering the circumstances.
• Screw This, I'm Outta Here: She deserts you on the spot if you decide to join Naoya and become the King of Bel. If you choose to spare your enemies on the 8th Day, though, she comes back.
• Squishy Wizard: Her stat build lends itself towards magic than physical combat, and has the second-lowest Vitality growth among the cast. Her reduced movement range also hurts her mobility, but she is compensated with above-average turn speed.
• Tsundere: More towards Atsuro than the hero, but it's there.
• The Unfought: In the original release, she is one of only three potential party members who cannot be fought under any circumstances. Overclocked changes this; she opposes you with force if you choose to become King of Bel and then murder the enemy demon tamers on Day 8.
• Violence is the Only Option: Decides to stop you in Naoya/Kaido's Inhuman 8th Day with Metatron's help.
• Vitriolic Best Buds: With Atsuro. Even though she can be fairly abrasive at times with him and snark at a majority of his ramblings, she does genuinely cares about him.
• The Watson: To Atsuro, mainly, but often plays the same role when others start revealing what they know.

Keisuke Takagi

Keisuke Takagi

Voiced by: Yūki Kaji (JP), Makoto Naruse (drama CD), Doug Erholtz (EN)

An old friend of Atsuro's from middle school who always used to stand up for others, but has become reserved and a bit timid. His Character Development largely hinges on the hero's choices after he goes Well-Intentioned Extremist. Will he realize the error of his ways and become The Atoner, or will his Knight Templar streak lead to tragedy?

---

• Adaptational Badass: In the game, Kaido kills him with hardly any difficulty if you're unable to stop him from going after Keisuke. In the manga, despite still being killed, he puts up a much tougher fight for Kaido.
• The Atoner: But only if convinced that he made a huge mistake.
• Berserk Button: He's protective of Midori as is, and will fight for her life; if you attack her after she's helped you, may God have mercy on you... because Yama certainly won't.
• Beware the Nice Ones: Normally a somewhat timid guy who nonetheless tries to help people out, even if they've just met. Push his Berserk Button and he will summon Yama, who will judge you and, more often than not, kill you.
• Breaking Old Trends: Members of the Law alignment are typically calm, soft-spoken, or even emotionless, with more angry and passionate characters typically belonging to the Chaos alignment. Keisuke, on the other hand, is a kid with a lot of pent-up anger at the world's injustices and the minute Yama gives him the power to act on that anger, he takes it without hesitation.
• Break the Cutie: Technically, he was broken in high school before you even met him... And then he snaps.
• Bully Hunter: Was one of these when Atsuro knew him in middle school. It ended up backfiring on him one day.
• The Cameo: At least someone who bears a really close resemblance to him◊ appears in Devil Survivor 2: The Animation as a JP's agent.
• Captain Ersatz: Pretty much agreed to be Light or Mikami with a demon instead of a magic notebook.
• Close to Home: Part of the reason he had his Freak Out was finding out Midori was going to die by the hands of the same people she tried to save, reminding him of his own traumatic experiences.
• Cruel and Unusual Death: If you don't keep Kaido from tracking him down, Pazuzu grabs him by the neck and fries him alive, turning him into a charred corpse right in front of your party before tossing him aside like garbage.
• Dark and Troubled Past: He was originally a laid back person who defended others from bullies, but eventually ran afoul with bullies in high school while defending one of their victims. The victim in turn joined the bullies against Keisuke for personal protection, fueling a psychotic hatred and Suppressed Rage against those he deems as selfish and immoral.
• Death by Adaptation: Is defeated and killed by Kaido in the manga even when Kaido helps in the fight against Kudlak, which in the game, would lead to Keisuke being saved.
• Dump Stat: He has only 16 Vitality at level 99, the worst in the party.
• Et Tu, Brute?: Keisuke's swing towards withdrawn cynicism and Knight Templar brutality after middle school is because somebody he saved from bullying in high school joined in when the bullies turned their attention to him.
• The Farmer and the Viper: In high school, he protected a classmate from some bullies... only for said classmate to join the bullies when they rounded on him. Nowadays, these situations are his Berserk Button, and a great way to bring his Knight Templar side to the forefront.
• Fragile Speedster: Of the main characters, he has the highest Agi growth and best turn speed... and the lowest Vit growth. However, this trait makes him useful if you're taking on a certain boss using a certain strategy.
• Freak Out: Proving that it might actually be scarier when you don't have Scary Shiny Glasses hiding the murderous rage in your eyes.
• Heel Realization: A possibility. Confront him in the right manner (i.e. by defeating Yama), and he will eventually realize that in his quest to bring justice to thugs inside the lockdown, he has become a thug himself.
• He Who Fights Monsters:
  • He acknowledges this himself, if you successfully redeem him. By using his power to prey on the weak, he had become what he hated so much, no matter how 'noble' or just his intentions were.
  • The protagonist can call him a bully when Keisuke's still in the middle of his Roaring Rampage of Revenge. Considering Keisuke's background, of which the protagonist had no knowledge of at that time, this actually manages to make his conviction falter, if only for a moment.
• Jerkass Has a Point: Or rather "emotionally unstable teenager has a point." If Atsuro and Midori confront him on Day 5 about the fact that he killed Kaido's men, Keisuke points out that he isn't just going around out attacking innocent people; the members of Kaido's gang that he killed were awful people, having beaten an old woman to death after she tried to give them food when they were starving.
• Karma Houdini: Averted; if you talk him down without a fight, Midori picks up the Conflict Ball and forces a confrontation that's arguably far worse than if you just beat up Yama.
• Knight in Sour Armor: More obvious after his Knight Templar stint. Assuming, of course, he lives past that point.
• Knight Templar: After his Freak Out and summoning of Yama, he believes that his "judgement spree" inside the lockdown, as brutal as it may be, will ultimately lead to a better world.
• Mutually Exclusive Party Members: In the original release, he cannot join on Naoya's route and cannot fight alongside Naoya or Kaido. In Overclocked, while Kaido now joins on Yuzu's 8th Day, he can absolutely never fight alongside Naoya.
• My God, What Have I Done?: If you manage to talk him out of his Knight Templar stint, it begins to dawn on him exactly what he has done and it absolutely horrifies him. It's almost another Break the Cutie moment for him, but with help from the party he can get the courage to start over and make amends.
• Never My Fault: Slips into this during his confrontation with Kaido, if it occurs. He tries to claim that Yama is the one judging and punishing sinners, Keisuke only being responsible for summoning him. To nobody's surprise, Kaido isn't impressed with this line of logic and subjects Keisuke to a Family-Unfriendly Death.
• Not Himself: Atsuro doesn't understand why he's suddenly become so withdrawn and timid.
• Not Quite the Right Thing: It's very easy to get him killed if you're not careful; you have to watch a couple of optional scenes, give Mari's bag to Kaido to distract him and give yourself some time to talk some sense into Keisuke, then choose the right dialogue options during the fight. If you fail either of the first two, Kaido will kill him before you can do anything, and if you mess up the last, Midori throws a temper tantrum.
• "Not So Different" Remark: In using Yama to kill the people he judges responsible for making the lockdown worse, he's acting no different from those using demon tamers as scapegoats... or the bastards using force to get what they want. Kaido even calls it on him, hard... right before killing him.
• Order Versus Chaos: Law-aligned, although he will also help on the neutral route. Will never join Chaos.
• Redemption Equals Life: Literally. You either redeem him, making him stop his crusade, or Kaido kills him.
• Required Party Member: If you choose to talk him down instead of beating some sense into him, Midori turns on you and brings Kaido down on your head. Naturally, he's required for the ensuing fight, and naturally, if he bites it its game over.
• School Bullying Is Harmless: Completely averted. Keisuke became a victim of cruel bullying after he changed schools. This left him with a seething hatred for those who pick on the weak which, alongside general social order in the lockdown falling apart, causes his rampage on Days 4 and 5.
• Screw This, I'm Outta Here:
  • Deserts you automatically at the beginning of Day 4 upon learning Midori is slated to be murdered by humans. The main overarching plot thread of Days 4 and 5 is to try to figure out how to get him back without him or Mari getting killed.
  • If you choose Yuzu's route, he deserts you at the beginning of Day 7 since he wants to try to find a way to stop the demon invasion outright. He can be convinced to rejoin you before you're made to see any combat, though.
  • He deserts you on the spot if you decide to join Naoya and become the King of Bel. Unlike Yuzu and Midori, he can't be convinced to rejoin under any circumstances.
• Shrinking Violet: Comes off like this at first, to Atsuro's shock. It's all but stated that he became like this as a direct result of the bullying he experienced.
• Silly Rabbit, Idealism Is for Kids!: Tries gently convincing Midori of this, growing a bit more forceful when she refuses to listen. To the point of where he actually scoffs at her when they catch him about to execute some crooked cops that they'd just met the day before, and she realizes they were hardly hampered by losing their COMPs.
• Sliding Scale of Gameplay and Story Integration: His AI prefers fighting the demons that attack him instead of running away to safety during the 2nd Day's battle in Toyoshima-ku where he's prophesied to die alongside other 49 people including Midori. While a good example of gameplay/story integration that hints at his issues, this tendency of his also makes the battle harder than it has to be — that is, by forcing the party to prioritize his enemies and heal him because he won't back down, which tends to leave him open for other demons' attacks.
• Stoic Spectacles: He generally tends to stick with one facial expression, though this gradually changes throughout the week. His reaction to Atsuro hinting at possible feelings for Midori is just adorable, though. It also makes his expression after his Berserk Button has been mashed that much scarier.
• Tranquil Fury: After his initial Freak Out and Yama's summoning, he returns to his normal calm disposition, even when trash-talking corrupt policemen, but it's clear that under the surface he is still seething with anger.
• Utopia Justifies the Means: Even if Yama's judgment eventually turns against him, at least he can make the world a better, safer place before then.
• Vigilante Man: After forming a pact with Yama, he goes around murdering gang members who torment survivors and any demons who get in his way.

Midori Komaki

Midori 'Dolly' Komaki

Voiced by: Mariya Ise (JP), Kana Asumi (drama CD), Erin Fitzgerald (EN)

A fifteen-year-old cosplayer who is known as the camgirl 'Dolly'. Due to the lockdown, she is stuck wearing one of her cosplay outfits. Extremely peppy and optimistic, her outlook on life borders on childishly simplistic.

---

• Ascended Fangirl: Of sorts. She gains access to magic and other such resources and is involved in a situation that superficially resembles that of the Magical Girl series she loves so much, but she actually is in a much darker genre. Left unchecked, that inability to perceive the difference will get her killed.
• Badass Adorable: She acts like a cutesy Magical Girl anime heroine... who can back that up with her Demon Tamer skills.
• Beyond the Impossible: It's a Running Gag that her innocence a la The Power of Love is actually helping the demonic situation. Surprisingly, this is even able to convince a Black Frost to join the main cast.
• Black-and-White Morality: She has a fairly simplistic view of good and evil and strong delusions on being a hero fighting the forces of evil.
• Breaking Old Trends: Characters aligned with Law in Megaten generally tend to be calm, stoic, or even emotionless. Midori... isn't, to say the least.
• Broken Bird: Strongly implied. Her father died when she was younger and his strong impression as a "Power Ranger" stuntman inspired an obssesion towards becoming a hero. It was due to this strong desire to become a hero that she eventually felt out of place with people her age resulting in a Friendless Background and bullying, and turned to the internet, which led to her becoming a famous internet cosplayer.
• Catchphrase
  Midori: Prepare for Magical Punishment!
• Character Development: Can gradually learn to accept others' viewpoints without spoiling her own innocence... provided you help her understand. And survive.
• Cloud Cuckoolander: She got caught in the lockdown wearing a cosplay outfit and her wild imagination goes off the gauge once she gains a COMP, believing herself to be a real magical warrior fighting evil beings.
• Conflict Ball: Picks one up if you talk Keisuke down instead of fighting Yama. Apparently she considers that an Anticlimax, and runs off to tattle to Kaido, forcing you to fight both of them.
• Cosplay Otaku Girl: As a character design point; since she didn't bring a change of clothes, she's stuck in the cosplay outfit she was in when they initiated the lockdown over the Yamanote circle. However, she doesn't mind much, claiming they just look like 'extra-cool everyday clothes' anyway. Those same clothes end up causing people to blame her for being a witch that summons demons once her heroine side goes out of control.
• Daddy's Girl: Her father's stories are pretty much her sole reason for being... her.
• Dual Boss: Twice. First, if you refuse to destroy Yama when you get the chance, Midori will get mad and run off to Kaido, forcing you to fight both of them. Second, she and Yuzu will join Metatron's side if you decide to butcher the tamers that come after you in Naoya's INHUMAN last day.
• For Great Justice: Together with love, justice is what she is fighting for and what she thinks makes her strong, which she tells to a certain Jack Frost.
• Genki Girl: In stark contrast to the rest of the people inside the lockdown, she's optimistic to a fault.
• Idiot Ball: Plays with this a lot. She's one stubborn little girl.
• Hero with Bad Publicity: She goes out of her way to save people using her demons, but due to the general public being unable to distinguish hostile demons from controlled demons, they see her as a Wicked Witch.
• Innocent Blue Eyes: Clear blue and pupilless, a hint at her child-like innocence.
• In the Name of the Moon:
  Midori: I'm Magical Dolly, the Warrior of Love! My magical punishment strikes all demons who do evil!
• Jack of All Stats: Has a relatively even spread, with a focus on Magic. She doesn't hit as hard as Yuzu, but can take hits better and has better mobility. She's also one of the Magic-focused characters who doesn't max that stat out in the end.
• Jumped at the Call: She really wants to be a hero, and the minute the possibily of being one presents itself, she snags a COMP from Atsuro and dives headfirst into the demon fighting business. Sadly, her COMP came free with an Idiot Ball.
• Leeroy Jenkins: When the main party defends people from demons, they always calmly explain what they are doing and that there is no need to be afraid of their demons. Midori, on the other hand, defends people by rushing on the scene, spouting In the Name of the Moon lines, and summoning her demons, utterly scaring the people she's trying to defend. If left unchecked this can get her killed.
• Love Freak: She is technically what Flonne would look like if her otaku side would explode. And work.
• Magical Girl: Wants to be one.
• Mutually Exclusive Party Members: In the original release, she cannot join on Naoya's route and cannot fight alongside Naoya or Kaido. It's subverted in the 8th Day if you spare the hostile demon tamers, in which case she comes back. Kaido also joins you on Yuzu's 8th Day, giving you another chance to have them fight alongside each other.
• Odd Friendship: Depending on how you handle Keisuke's storyline, she develops one with Kaido of all people.
• Order Versus Chaos: Law-aligned, although, she can be convinced to join you in the Chaos route, same as Yuzu, providing you don't kill humans. Reluctantly.
• The Power of Love: She uses this principle on a Jack Frost she defeated to teach him to be strong. Not only does this work, but it also turns said Jack Frost into a Black Frost. And if you help him, he'll even become an Optional Party Member.
• Required Party Member: On day 6, there's an optional event where you can help Black Frost protect some weaker demons from a bunch of demon tamers where Midori is required. Completing it causes said Black Frost to join you on Gin and Naoya's 7th days.
• Say My Name: If you mess up a certain part of Day 5. "Aaaaaaah! Keisuke! Keisukeeeeee!"
• Screw This, I'm Outta Here:
  • Deserts you on Day 5 if you decide to talk Keisuke down without a fight.
  • If you choose Yuzu's route, she deserts you at the beginning of Day 7 since she wants to try to find a way to stop the demon invasion outright. She can be convinced to rejoin you before you're made to see any combat, though.
  • She deserts you on the spot if you decide to join Naoya and become the King of Bel. If you choose to spare your enemies on the 8th Day, though, she comes back.
• Shipper on Deck: For the hero and Yuzu, even more so in Overclocked on Naoya's Good 8th Day. She teases Yuzu about blushing over the main protagonist and directly asks the player if the two of them are going out, being upset if the player says she's just a childhood friend or getting excited if he responds that their relationship is a secret. Given how much she believes in The Power of Love, it makes sense that she'd be interested in that sort of thing.
• Too Dumb to Live: Before her Character Development, she greatly underestimates the demon situation, constantly throws herself into danger while travelling alone, and refuses to listen when the party tells her how stupidly she's acting. It takes multiple near-death experiences before she gets better.
• Violence is the Only Option:
  • In the name of justice, she does this to the Hero with Metatron's help in Naoya/Kaido's Inhuman 8th Day.
  • Also thinks that this is the proper way to redeem a Fallen Hero. Just talking it out with him will get her to force a fight.
• Wide-Eyed Idealist: She relies on The Power of Love and trusts the people inside the lockdown to do the same, not seeing how cynical and crapsack the situation really is.
• Wrong Genre Savvy: Upon getting her COMP, she immediately starts running around like she's the heroine of a Magical Girl anime, blissfully ignorant that civilians are terrified of all demons, including the ones she uses to fight.
• You Remind Me of X: Keisuke says to protagonist and Atsuro that Midori remind him of his sister.

Amane Kuzuryu

Amane Kuzuryu

Voiced by: Mamiko Noto (JP), Yui Kano (drama CD), Laura Bailey (EN)

Sixteen years old and the chosen maiden of the Shomonkai, a religion devoted to 'overcoming God's ordeal'. Highly charismatic, with an undeniable presence, yet bearing an air of mystery around her as well. Takes an interest in the hero and his friends.

---

• Aborted Declaration of Love: In the manga, when Kazuya is about to head to the demon world, Amane attempts to reveal that she grew feelings for the protagonist, but bails at the last second.
• Badass Adorable: She's one of the strongest human magicians in the world and possibly humanity's most unwavering champion. She's also got an extremely cute smile and badly needs a hug.
• Betty and Veronica: The Veronica to Yuzu's Betty towards the protagonist's Archie.
• Captain Obvious: In her own route, when Naoya warps away after being defeated. "...Cain ran away."
• Demonic Possession: Coupled with Angelic Possession, to boot.
• Disappointed in You: Expresses this sentiment to the party if you decide to run the blockade on Day 7.
• Dual Boss: At the end of Yuzu's 7th day, you fight her alongside Izuna.
• Dump Stat: She has a measly 17 Strength at level 99, the worst in the party.
• Emotionless Girl: Quiet, calm, and composed. Her smiles, when they appear, are slight and subtle. Subverted in that she was taught to be one, but grows more active after spending some time with the group and free of her father's influence.
• Final Boss: Of Yuzu's route, alongside Izuna.
• Glass Cannon: She starts off with insane Magic and not much else.
• Heel–Face Revolving Door: Sides first with Belberith, then God, and finally (in Naoya's Human Eighth Day) Abel. As she notes, her only goal is humanity's survival, so she will always side with those that care the most about humanity.
• Hero Antagonist: In Yuzu's 7th Day and Naoya's Evil 8th Day. In both cases, you've become a threat to humanity and need to be stopped by force.
• I Just Want to Be Normal: On her 8th Day, she laments how she never got to have a normal high school life.
• Impossibly Cool Clothes: As seen in the supplemental material◊, the sleeves of her Shomonkai robes are linked together in one big, sweeping loop that drapes low behind members' backs, and hers goes in between her legs. Somehow, she has absolutely no problem moving gracefully in this.^note Her sprite in the game has the cloth behind her back, but that should still make walking awkward.
• Killed Off for Real:
  • In Atsuro's route, Remiel reveals that Belberith likely killed Jezebel for her power. Given how entrenched into Amane's soul Jezebel was and how Amane's body is controlled by Remiel throughout the entire route, the implications for Amane are not pleasant.
  • In Naoya's Evil 8th Day, you kill her.
• Lady of Black Magic: Elegant, composed, and graceful; that's basically Amane in a nutshell. She also has the highest magic growth in the game.
• Messianic Archetype: The holy maiden of the Shomonkai, chosen to sacrifice herself to save humanity from God's Ordeal. Except for the part where she sacrifices herself to a demon, and saving humanity from God's Ordeal is worse than failing it.
• Mighty Glacier: Of the magical variety. She has decent vitality, has an astounding Magic growth (she maxes hers out earliest among the entire party), but has sub-par agility and a movement range of only 3.
• Miko: She's known as the maiden of the Shomonkai, although they don't have a shrine.
• Mind-Control Eyes: Whenever Remiel takes over. Though given how her eyes are always a flat, pupiless lavender, the effect's made more obvious by Dramatic Wind and standing in a way that gives the impression that she's almost floating.
• Minidress of Power: The robes she is wearing end as high above her knees as a miniskirt would and are rather form-fitting, too, invoking this trope.
• Ms. Exposition: She takes over this role for Remiel after he leaves her, in the routes where you help him defeat Jezebel.
• Mutually Exclusive Party Members: In the original release, she cannot join on Naoya's route and cannot fight alongside Naoya or Kaido. It's subverted in the 8th Day if you spare the hostile demon tamers, in which case she can be convinced to join you.
• Navel-Deep Neckline: Her evil clones (created by Jezebel during the Battle in the Center of her Mind) wear the same robes as her but have navel deep necklines.
• Order Versus Chaos: Subverted. She appears to be Law-aligned, but while that's her preference, she's actually humanity-aligned, and will consistently help you out if you're fighting to protect humanity, whatever method you use.
• Rei Ayanami Expy: Emotionless Girl? Being screwed over by her father? Secretly the host of an angel and working towards a world of perfect unity? One Rei clone, coming right up!
• Senseless Sacrifice: She'll attempt one on Naoya's Good 8th Day. To buy you some time to escape the Anti-Overlord Shomonkai, she intends to give her life, and she will rush the nearest group of them and die automatically to some of the group setups, netting you a game over. All this despite you having no intention or goal of escape, and outright declaring the intent to protect her.
• Sugar-and-Ice Personality: Most of the time she acts aloof and people find her Emotionless Girl qualities intimidating, yet she really is friendly toward you, most of the time.
• Token Good Teammate: One of the few SMT Law-aligned characters who is not a Knight Templar, instead genuinely wanting to create a better world. She also joins on Gin's route and Naoya's 8th Day, despite them not ending with her ultimate goal achieved, as she wants to protect humanity.
• Utopia Justifies the Means:
  • Twice over; first she subscribes to the Shomonkai's view of how to obtain paradise, but later decides she likes Remiel's version better.
  • If taking the human route for Naoya's 8th Day, she will pledge allegiance to the protagonist, explaining that her only concern is that humanity gets the best ending possible.
• Willing Channeler: Initially for Jezebel, then much more willingly for Remiel.

Eiji "Gin" Kamiya

Eiji 'Gin' Kamiya

Voiced by: Katsuyuki Konishi (JP), David Vincent (EN)

Runs the bar 'Eiji' in Omotesando. He acts as Haru's guardian, and is close friends with her and Aya. Is investigating certain things on his own as well...

---

• Big Brother Mentor: Towards Haru, mainly, though he can grow into this for the hero and his friends as well.
• Chick Magnet: Yuzu thinks rather highly of him. Haru trusts him implicitly, and Aya was his lover. Shoji even admits she finds him to be very hot and kickass.
  Shoji: He was smokin' hot.
• Death Seeker: In a moment with Haru after Belial is defeated, she says she wasn't the only one who thought life had no meaning anymore after Aya's disappearance. This explains why he doesn't even care that his death clock changes the moments he picks up the Distress Ball by going after the Shomonkai alone. Luckily he snaps out of this, though, and decides to dedicate himself to getting back the Tokyo that Aya loved so much, i.e. the Tokyo that wasn't overrun by demons.
• Delinquent: Former, describes himself as an adult Tadashi who changed his ways after falling in love with Aya. He effectively sees himself as no different from Tadashi and would have been the same way all his life if he had not met someone like Aya.
• Desperately Looking for a Purpose in Life: He implies he was like this before meeting Aya. The entire world looked gray to him, he didn't care about anything as a violent delinquent, he had no goals, and nothing was ever his fault. After meeting Aya, he mellowed out a lot and began to appreciate life, especially the simple things he couldn't see in the past.
• Distress Ball: An odd male example; when you tell him of the Shomonkai's offer to meet him at a specified time and date to discuss Aya's disappearance, he charges blindly forward on his own despite it being an obvious set-up.
• Edible Theme Naming: His nickname comes from gin, a type of alcoholic drink. Fitting, as he's a bartender.
• Escort Mission: At one point, you have to save/defend him from an ambush set up by Azuma.
• Face of a Thug: Just look at his official art. He looks intimidating, but in truth he's very laid-back and, unlike many other demon tamers, tries to use his COMP sparingly (i.e. only to defend himself or other innocent people).
• Heroic Neutral: For the most part, he's content to hole up in his bar and ride out the lockdown in relative safety. Of the four characters who need to be rescued in order to earn titles in Overclocked, he's the only one who needs to be actively provoked by the player into endangering himself.
• Jack of All Stats: While he keeps a respectable Strength, Vitality, and Agility growth, he sacrifices specialization in those stats to also keep his Magic afloat. While it gives him a fair amount of flexibility in what he can equip, he does end up paling in comparison to other physical specialists.
• Love at First Sight: According to Kaido, Gin and Aya only needed their first conversation to know that they were the ones for each other.
• Lying to Protect Your Feelings: Tells Haru that Aya had gone overseas, when in actuality, she had gone missing.
• Mutually Exclusive Party Members: He's only available on his own route, and can never fight alongside Naoya or Kaido.
• Never My Fault: Admits that he was like this before he met Aya. Now, though, he recognizes it in today's youth. It annoys him, as he has learned that it's a good thing to not always take the easy road, make mistakes and own up to them.
• Only Known by Their Nickname: Everyone calls him 'Gin' instead of his real name, which he uses for his bar instead.
• Order Versus Chaos: Neutral-aligned.
• Waistcoat of Style: Fits nicely with his occupation as proprietor of a modern bar, yet also makes him blend in easily with the rock crowd as Haru (or, in the past, D-Va as a whole) gives concerts.

Naoya

Naoya

Voiced by: Kisho Tanigawa (JP), Hiroshi Kamiya (drama CD), Kyle Hebert (EN)

The hero's twenty-four year old cousin and brother figure, and a genius programmer. Gave the hero and his friends their COMPs shortly before the plot hit Tokyo; his motives for doing so are shrouded in mystery.

---

• Aloof Older Brother: In terms of what exactly is happening (including the sudden appearance of demons, the way the COMP works, and other such stuff) he is a lot better informed than the main trio. Don't expect him to help you out, though; even when you finally meet up with him again at the end of the 5th Day, he still tells you nothing more than you strictly need to know. You can call him out on this, though he hardly seems to care.
• Badass Bookworm: Created the Demon Summoning program all on his own, and is very capable in battle.
• Badass Long Robe: His attire wouldn't be that noteworthy if not for his robe with the Matrix Raining Code on it.
• Bad Guys Do the Dirty Work: On Yuzu's 7th day, he challenges the SDF forces at Shinjuku so that the party doesn't have to fight humans.
• Biblical Bad Guy: Cain.
• Big Bad: Forms an Ensemble with Belberith and Metatron, though you can end up on his side.
• Big Bad Wannabe: He's a brilliant Chessmaster, make no mistake, but his enemy is God. He's out of his weight class, he has no hope of winning the game himself, and the best he can do is get the player character to rebel for him.
• Big Brother Instinct: Even though he tries to manipulate the protagonist in order to accomplish his goals, he does genuinely care for him more than his revenge against YHVH and will take the riskiest choice for his survival, to the point that he even goes out of his way to pull off a Big Damn Heroes moment to save Abel from Okuninushi's assaults and ultimately turns the tables against him.
• Big Damn Heroes: In the 8th day of Amane's route, the heroes are fighting an uphill battle where the final boss keeps resurrecting, with added strength each time. Then, once his attacks have gotten all but devastatingly powerful, Naoya shows up and sets up a barrier that not only prevents the boss's resurrection, but weakens his attacks as well.
• Cain and Abel: Cain to his cousin's Abel, but it's subverted in that he doesn't actually want to kill him. Played straight if you decide to take certain routes, where he will fight you. In fact, the original Cain, and unlike the MC, he remembers all of it.
• The Chessmaster: It's made clear very early on that Naoya is a brilliant long-term planner and has been setting up the playing field since well before the game starts. Being able to see the future doesn't hurt.
• Crazy-Prepared: There is not a thing that Naoya does that isn't some sort of Batman Gambit, though he doesn't do all that well if you don't play into his hand. It's justified — Naoya's had a LOT longer to plan things out than most people.
• Deadpan Snarker: In his own route, if you answer a certain question wrong, he asks you if it was a pitiful attempt at humour. In Atsuro's route, he gets annoyed with Atsuro's eagerness.
  Atsuro: Oooh, what about me, Naoya!? What should I do...!?
  Naoya: ...You can start by putting a lid on it.
• Defeat Means Friendship: Invoked by himself in Atsuro's route. You want his help? Sure, if you defeat him first.
• Defrosting Ice King: Strangely enough, in Amane's 8th Day with Okuninushi describing it as a 'small droplet of water in thousand year old ice' after he comes to your aid against Okuninushi, with his heart being softened enough to meet Okuninushi's expectations.
• Devil in Plain Sight: He's none other than Cain, and he has been your cousin/brother figure for your entire life.
• Don't You Dare Pity Me!: His reaction if you tell him you forgive him in Amane's route.
• Expy: Disregarding looks, this is actually the second time the Megami Tensei series had a young genius programmer who developed the demon summoning program using the same exact logic^note (In that the program is replicating the process of a summoning ritual)... since 1986.
• Fate Worse than Death:
  • Every time he reincarnates, he remembers everything from every single past life, including the one where he killed his brother Abel out of jealousy. He is thus unable to escape his sin. The sad thing is that Cain could break this cycle by using the time to reflect on — and repent for — his sin, but he's far too consumed by revenge to do so.
  • Overclocked elaborates on this. God set up the Cain and Abel scenario in order to get a murderer and a martyr. Cain feels that he was unfairly manipulated into killing his brother by an unjust God, and thus refuses to atone to a God that used him in such a manner.
• First-Name Basis: Since he shares his last name with the player, everyone just calls him Naoya.
• "Get Back Here!" Boss: Naoya + Devil Speed + Phantasma + enemy respawn points + Naoya respawning those respawn points if you destroy them = a discouraging beginning to Atsuro's route.
• Goggles Do Nothing: He has a noticeable pair of glasses that he never wears. They're most likely reading or computer glasses.
• Graceful Loser: After defeating him in Atsuro's route, he, quote, "concedes defeat", admits that he underestimated the group, and agrees to help them with the server. Although, admittedly, it could've been partially due to the fact that he knew that the group was being assisted by angels.
• Heel–Face Turn:
  • In Atsuro's route, he puts his own ambitions on hold to help the hero.
  • Also applies to Amane's 8th day route, where he helps the main characters defeat the final boss.
• Heel Realization: It takes a while, but the protagonist actually moves his heart a little when he manages to get through to Naoya that he doesn't hate him for killing him in their past life. This prompts Naoya to aid them in the final battle of Amane's route. However, this does not mean that he forgives or shall atone to God. Naoya simply allows his love for his brother to overcome his near consuming hate for God in Amane's 8th day.
• Hello, [Insert Name Here]: Partial example; since they're cousins, he shares his surname with the hero.
• Hidden Agenda Villain: ...If "villain" is the proper term. Any way you look at it, it's pretty clear from the beginning that he's up to his neck in the events that triggered the lockdown crisis, but you don't learn what his end goal is until Day 5 or why he's doing what he's doing until he goes on a Motive Rant late in Amane's Day 7 or you side with him and learn his true identity from the angels on his own Day 7.
• Hypocrite:
  • Rags on about not relying on others, but his entire plan depends on the MC. Will not be happy if called on it.
  • Hates God for manipulating him, and for putting humanity through dangerous and painful trials. Manipulates the MC and puts him through dangerous and painful trials.
• Idiot Hair: It's pretty small, but it's prominent enough to be visible on his battle sprite.
• Impossibly Cool Clothes: Check out that Badass Long Robe, complete with Matrix Raining Code pattern. Think that's handmade? Maybe he gets around with Phantasma?
• Insufferable Genius: Genius enough to build a server to summon demons, which includes somehow finding a way to harvest emotions from the internet, and he's also perfectly aware that you know absolutely nothing about what's going on. The disdain in his voice, though mostly towards Yuzu and Atsuro, is palpable.
• Jack of All Trades: His stat distribution is relatively balanced when compared to the other characters, with a slight preference towards Magic. His stats are distributed such that he can meets the bare minimum to equip a wide variety of skills from the get-go while maximizing Magic, making him very flexible while outperforming other generalists.
• Jerk with a Heart of Gold: Shows absolutely no consideration for those he considers beneath him and thinks nothing of manipulating others to suit his own ends. When Fushimi calls him out on the destruction he's helped cause, Naoya just laughs in his face. However, his interactions with the protagonist and Atsuro in the latter's route shows that he is capable of genuine compassion.
• Matrix Raining Code: His cloak's aesthetic.
• The Mentor: To Atsuro, and during the first day, he was sort of a Stealth Mentor to the group, getting them used to their COMPs.
• Mr. Exposition: He's responsible for explaining whatever parts of the plot that Amane and Remiel isn't, particularly on his route.
• Mutually Exclusive Party Members: In the original release, he's only available on his own route, and can never fight alongside Yuzu, Midori, Keisuke, Gin, Izuna, or Amane. In Overclocked, if you spare the hostile demon tamers, Yuzu and Midori come back while Izuna and Amane can be convinced to join you. He still can absolutely never fight alongside Gin or Keisuke, though.
• My God, What Have I Done?: A lot of his motivation is based around guilt for having become the original murderer, and blaming God for driving him to feeling it was necessary to appease Him.
• Nay-Theist: He knows God exists. He also hates His guts. For good reasons.
• Obviously Evil: Let's see... Slasher Smile, Red Eyes, Take Warning, and so on. Subverted in that he's better described as "chaotic" than "evil."
• Offing the Offspring: Metatron is on his list of things that need to die. He confirms that Metatron was once Enoch, though not which one, a notable detail as the series has combined figures of the same name before, the son of Cain or the descendant of Seth. Either way, he has a younger family member marked for death.
• Order Versus Chaos: Chaos-aligned.
• Pet the Dog: He comes to his cousin's aid in Amane's 8th Day, proving to Okuninushi that Naoya cares about the Hero and proves to him that the Hero is indeed the Messiah.
• Power Floats: In routes where you fight him, his character visibly floats above the ground. Might be due to his tendency to have have demons with Flight, Devil Speed, and Phantasma.
• The Punishment: He's really turned that immortality into the exact opposite of what God intended he should use it for.
• Rage Against the Heavens: "God's no friend of mine." It was changed to "I follow no god" in Overclocked, which might be referring to his refusal to cooperate with the Shomonkai and Belberith as well as his dislike of God. However it seems that as long as God just leaves the world alone, he'll give up his desire for vengeance, as seen in Yuzu's 8th Day where God abandons humanity.
• Reincarnation: He's the reincarnation of Cain, with fully-intact memories of every single reincarnation he's had for the thousands of years since he killed Abel.
• Required Party Member: In his own route, he is required for the battles against Jezebel and the angels.
• Slasher Smile: He's often seen with a malicious smile on his face.
• Strike Me Down with All of Your Hatred!: Attempts to invoke this in Amane's route, where he asks the MC whether he hates Naoya and wants to kill him. However, how successful he is depends on how you decide to reply.
• Suspiciously Similar Substitute: Has almost identical stats to Yuzu (just slightly higher Vitality and slightly lower Agility), which is sure convenient when they leave your party just before his route starts.
• Villainous Breakdown: He goes completely and utterly batshit insane when you fight him in Amane's route. He goes on to reveal that he's Cain, and he tells the MC to hate him and kill him. And when you beat him? After saying a few things, he ends it off by laughing before warping outta there. He also gets one mid-battle if you choose certain dialogue options. Specifically, he demands to know whether or not you hate him for killing and later manipulating you. He absolutely flips if you tell him you never did.
• Villain with Good Publicity: At leas as far as the heroes are concerned. A big part of the reason they go along with summoning demons and fighting during the first few days is because Naoya instructs them to through the COMPS. Several times they question his motives, but it's always stated that they trust him and have the firm belief that he wouldn't intentionally harm them. Surprising, seeing how in his interactions with Yuzo and Atsuro he shows little concern or respect for them.
• We Cannot Go On Without You: In his version of the Jezebel fight, he's the only thing allowing you to move in and out of Amane's soul. If he goes down, it's Game Over.
• Xanatos Speed Chess: If you take Atsuro's route, he shrugs and helps out, and next time Babel goes out of control, he'll be in an even better position to make a King of Bel.

Tadashi "Kaido" Nikaido

Tadashi Nikaido

Voiced by: Yasuhiro Mamiya (JP), Kentarō Itō (drama CD), Travis Willingham (EN)

The nineteen-year-old leader of the Shibuya Daemons, a charismatic gang known for its vast information network. Goes by the nickname 'Kaido'. Pursues power for his own personal reasons.

---

• Adaptational Context Change: How he awakens Pazuzu in the manga is very different than how he does in the game. In the game, he awakens it out of frustration when it looks like he's about to lose a demon hunting bet he made with the heroes. In the manga, he awakens it after finding out the Shibuya Daimons were slaughtered by Keisuke.
• Anger Born of Worry: After you helped Kresnik defeat Kudlak, he chews Mari out for going after the murderer alone, since she means more to him than she thinks.
• At Least I Admit It: To him, all people are ugly, selfish, and power-grubbing underneath and try to solve all their problems with force — he just doesn't see the point in trying to hide it. This comes to light when he ends up in a fight with the resident Knight Templar of the lockdown and ends up explaining how they're not so different in using the fact that they're more powerful than others to bully them into following their point of view, just before he uses Pazuzu to strangle and fry his opponent to death.
• Baritone of Strength: Sports a rather deep voice in Overclocked, befitting his position as a gang leader and a very powerful Mighty Glacier in battle.
• Blood Knight: While initially he may seem relatively friendly and tame, throughout the story, it's revealed he doesn't hesitate to kill anyone who stands in his way, and occasionally even enjoys it.
• Breaking Speech: Delivers a few blunt versions of these. Like when he calls Keisuke out for becoming like the bullies he wanted to fight before killing him.
• Cycle of Revenge: Some of his followers are killed as vengeance for preying on the weak, prompting Kaido to start his own hunt to take revenge on their murderer.
• Delinquents: At first, Atsuro states Kaido's gang is charismatic. But then, Kaido goes insane with power when he gains a COMP. Except in the Messiah 8th Day.
• Developer's Foresight: If he is present for the second battle against Kudlak, whenever he enters a skirmish with Kudlak and his team's attacks would kill him he will leave him at 1 HP so that Mari can kill him.
• Dual Boss: If you choose to redeem Keisuke without fighting him, he fights you alongside Midori.
• Dump Stat: He has a measly 14 Magic at level 99, second-worst in the party (only beating out Izuna).
• Enemy Mine: With Midori, if she thinks Keisuke's about to pull a Karma Houdini.
• Heel–Face Turn: During the Messiah 8th Day, he does this without actually joining the party. He prevents demon tamers from leaving the lockdown and cheers you on from the sidelines. He also aids the group in Yuzu's 8th Day to take down Belberith.
• Hopeless Suitor: Hopes to win Mari's love after the death of his brother, but fails every time.
• Might Makes Right: His personal philosophy.
• Mighty Glacier: His Strength and Vitality stat growths are very high, at the cost of low Agility and the lowest turn speed in the cast.
• Mutually Exclusive Party Members: In the original release, he's only available on Naoya's route, and can never fight alongside Yuzu, Midori, Keisuke, Gin, Izuna, or Amane. In Overclocked, if you spare the hostile demon tamers, Yuzu and Midori come back while Izuna and Amane can be convinced to join you. In addition, he now joins on Yuzu's 8th Day, allowing him to fight alongside Keisuke. He can never fight alongside Gin under any circumstances, though.
• Odd Friendship:
  • Develops one with Honda.
  • Depending on how you handle Keisuke's storyline, he develops one with Midori of all people.
• Order Versus Chaos: Chaos-aligned.
• Roaring Rampage of Revenge: Prone to these. Keisuke's arc ends with him going on one if you bungle it, and Mari's arc involves him either joining on said individual's rampage against Kudlak or going on his own separate one if said first individual is murdered.
• Sibling Triangle: Loves his dead older brother's fiancée. Awk-ward...
• Those Two Guys: He spends the first few days of the lockdown working with Honda most of the time.
• Tsundere: Towards Mari. He's usually very harsh towards her whenever she's around, but acts more deredere when he tells the protagonist about her or right after he chews her out for going after Kudlak alone.
• Unstoppable Rage: If you fail to find Mari's bag and get it to him, he stumbles on Kudlak killing her and goes absolutely apeshit, complete with Skyward Scream and Roaring Rampage of Revenge.
• Worthy Opponent: Often, he will call The Protagonist this. Later on, he will also call this for Keisuke, whom he just killed.

Mari Mochizuki

Mari Mochizuki

Voiced by: Shiho Kawaragi (JP), Kimberly Brooks (EN)

Another old friend of Atsuro's; she tutored him back when he was in middle school. Since then, she's achieved her dream of becoming an elementary school nurse. Has a calming influence on others, due to her kindly and compassionate nature.

---

• Badass Adorable: A Demon Tamer who happens to look very Moe despite being an adult.
• Beware the Nice Ones: She's a nurse and one of the sweetest people you'll ever meet. She's fully willing to murder anyone who opposes the Overlord.
• Demonic Possession: By Kresnik, in a mutually beneficial pact to take on and take out Kudlak.
• Expy: She was specifically designed to look like a feminine Kresnik, who debuted in Devil Summoner.
• Her Heart Will Go On: Her boyfriend was the first victim of the bloodless murders; it's suggested he was going to propose to her in the park. She gets revenge, then finds the strength to move on without him, possibly joining your team in the process.
• Hero Harasses Helpers:
  • When Mari offers to help, you can't accept outright — both options involve discouraging her, either through outright rejection or asking her to think it over first. In the latter case, she seriously mulls it over, then shows up with her own COMP.
  • If you decide to slaughter humans, Kaido will force her out of the group. While she supports the PC, Kaido won't let her be involved in Dirty Business.
• Hidden Depths: Who would think that this kindly school nurse would be willing to slaughter anyone who dares oppose the overlord?
• Mighty Glacier: Mari's stats focus on Magic and Vitality. Compared to Amane she has the advantages of more Vitality and mobility (can move 4 spaces every turn compared to Amane's 3), on top of a little more Strength for equipping other skills, but has the flat-out worst Agility of the party (only 18 at level 99).
• Only I Can Kill Him: Or rather, Kresnik, the demon inside of her, is the only one who can kill the vampire Kudlak. Handwaved in that Mari has gotten hold of Kudlak's Achilles' Heel. And there's also the fact that if Kudlak's not killed with said Achilles' Heel, he simply reincarnates stronger than ever...
• Optional Party Member: She is one of only two playable characters who isn't guaranteed to be unlocked on any route. To get her to join on Day 7, you have to help her kill Kudlak on Day 5. It also takes some finesse to pull this off without getting Keisuke killed in the process.
• School Nurse: She once a tutor at Atsuro middle school. Now, she's elementary school nurse. After the lockdown, she's treat people and kick demon ass.
• Shout-Out: She shares her last name with another known, important character.
• Silk Hiding Steel: A kind-hearted nurse who willingly lets a demon possess her and expresses willingness to commit cold-blooded murder in the Overlord's name.
• Token Good Teammate: Her friendship with Kaido lets her join even on his and Naoya's route. But Kaido and the others make her leave if the Main Character decides to kill whoever gets in his way, as they don't want her involved in that kind of bloodshed. She's actually willing to go along with it, and tries to defend his actions.
• Undying Loyalty: Mari will back whatever choice you make when it comes to dealing with the Bels. She only leaves the party if you kill humans because Kaido won't have her involved in that kind of Dirty Business, even if she's willing to do so.
• The Unfought: She is one of only two (three in the original version) potential party members who cannot be fought.
• Willing Channeler: Letting Kresnik possess her so that she can have a hand in defeating Kudlak.

Misaki Izuna

Misaki Izuna

Voiced by: Takako Honda (JP), Karen Strassman (EN)

A member of the Japan Special Defense Forces who is absolutely dedicated to ensuring the lockdown is a complete success. After all, she's well aware that there are worse options out there...

---

• Brutal Honesty: Atsuro notes that she doesn't exactly mince words. She responds that it would serve no meaning, as there are more important things to worry about, i.e. the lockdown.
• Crippling Overspecialization: At first glance, her stat layout looks ideal for a fighter; what do they need Magic for? Well, quite a lot, as it turns out, because many passives (and the few spells useful to a fighter, such as Diarahan) have a Magic requirement. They're low enough that Atsuro can usually hit them without issue, but Izuna has no such luck. She's really good at hitting things, but that's genuinely all she can do. Since Magic also functions as magic defense, this also gives her an Achilles' Heel against magic attacks — defensive passives can help with that, but the Magic requirement strikes again.
• Determinator: She will follow her orders no matter what, and she became a Demon Tamer and entered the lockdown willingly, knowing she just signed her death warrant in the faint hope of possibly ending the demon invasion by doing so, knowing and not giving a damn she could die, just as long as she fulfills her duty in the process.
• Dual Boss: At the end of Yuzu's 7th day, you fight her alongside Amane.
• Dump Stat: She has a positively dreadful 8 Magic at level 99, the single worst stat of any party member in either Devil Survivor game who isn't the protagonist.
• Fiery Redhead: She has a bit of a temper, though this might be the result of the stress she's under.
• Final Boss: Of Yuzu's route, alongside Amane.
• Hazy-Feel Turn: She can pull this off in Naoya's 8th day, defecting to the merciful Overlord's forces, despite still having doubts as to his intentions for the world, coupling this with exposing her superior's actions to public scrutiny. Despite the moral ambiguity, it's probably the most heroic thing she ever does.
• Honor Before Reason: Averted. She calls her direct superior out on his stance that the special forces shouldn't have to depend on a bunch of kids. He agrees with her and tells her to give the protagonists all the information she deems necessary.
• Late Character Syndrome: She actively lampshades this in most of the situations where she joins.
• Lightning Bruiser: All of her stats are above average, except Magic and MP.
• Magically Inept Fighter: She has great stats across the board, except for her magic. Her magic... ain't.
• Mutually Exclusive Party Members: In the original release, she cannot join on Naoya's route and cannot fight alongside Naoya or Kaido. It's subverted in the 8th Day if you spare the hostile demon tamers, in which case she can be convinced to join you.
• My Country, Right or Wrong: She really wants to prevent the Final Option from being used, but recognizes it may be necessary.
• Order Versus Chaos: Neutral-aligned. Will join in the chaos route, assuming the protagonist does not kill the humans.

Black Frost

Black Frost

A demon that Midori helped to understand The Power of Love. Unlike all demons, this Jack Frost is a friendly one. Following justice, Jack Frost turned into a Black Frost to aid his demon friends.

• Blunt Metaphors Trauma: After you help him out, he tells you he'll make sure to come rescue you if you ever find yourself in a "tight freeze". Yuzu says he probably meant "tight squeeze".
• Cloud Cuckoolander: Has shades of this in his in-battle dialogue, most notably when Babel assumes its final form, leading him to exclaim that it's transformed into "A giant churro!" Belberith, meanwhile, is a yummy meatball.
• Dark Is Not Evil: He fights for love and justice, and immediately agrees to not kill the enemy demon tamers when Midori asks him to, and to just take their COMPs instead.
• The Dragon: If you follow Naoya's Route's 8th Day in Overclocked, he becomes this to the Overlord since he is the only party member who can follow him into the demon realm.
• For Great Justice: He lives just for this.
• Heel–Face Turn: Starts out as a regular Jack Frost fighting humans For the Evulz. Midori then teaches him The Power of Love and, depending on the route, he will team up with you, even if your goal is to send all demons back to hell.
• It Has Been an Honor: When he gets send back to hell in Gin's route, he says he will remember the time he spent with you fondly and will keep spreading the message of love and justice in hell.
• Lethal Joke Character: He has Yuzu's movement range, but not her speed, making it difficult to get him anywhere. His stats are balanced, when specialization is usually the best bet. He also comes with two innate immunities which none of the human leaders have. While he does have an elemental weakness, filling his Passive slots with immunities can make him Nigh-Invulnerable and almost negate his poor Vitality growth.
• Love Freak: A side effect to his love for justice.
• Mighty Glacier: He has poor Agility and mobility, but his innate elemental resistances can be exploited to make him a very tanky party member.
• Nigh-Invulnerability: Made possible by his innate ability to reflect Fire and Ice attacks. You can then use his three passive skill slots to make him either null or reflect Phys, Elec and Force, making him only vulnerable to Almighty and Curse attacks, which aren't all that common and deal neutral damage to him anyway.
• Optional Party Member: He is one of only two playable characters who isn't guaranteed to be unlocked on any route. To get him to join on Day 7, you have to view an optional event between him and Midori on Day 3 and then help him protect some weak demons on Day 6.
• Plucky Comic Relief: He'll be this whenever you take him along to your important battles.
• The Power of Love: A very unique case. Normally, Jack Frosts can only become a Black Frost through enough hate. However, this Black Frost became one because of love and justice, despite those obviously being the opposite of what makes a Black Frost.
• Power Up Full Color Change: What happens when a Jack Frost achieves through justice, love, and trying hard to become strong as Midori puts it in this game, apparently. Yuzu Lampshades this.
  Yuzu: I-I don't think trying hard had anything to do with its color change...
• Samurai: Claims to be one.
  Gin: Okay, first of all... This guy ain't a samurai.
• Took a Level in Badass: He takes TWO of those levels: Not only he becomes a Black Frost, but if the player follows Naoya's Route in Overclocked, Black Frost ends up becoming the Hero's second-in-command as the Overlord.
• Verbal Tic: Adds "hee-ho" in almost every sentence he says. Sometimes it's just "[insert verb here]-ho". It's a hee-Frost thing, ho.

NPCs

Yoshino "Haru" Harusawa

Yoshino Harusawa

Voiced by: Junko Minagawa (JP), Amanda Winn-Lee (EN)

Twenty-year-old vocalist for the indie rock band 'D-Va' who goes by the stage name 'Haru'. While the band is currently on hiatus, Haru still performs solo. Very close to her mentor and fellow member, Aya. Also suicidally depressed, believing she's the one responsible for summoning the demons in the first place.

---

• Barrier Maiden: Zigzagged in that Haru herself doesn't have any magical powers, but Aya's sequencer draws demons to her. Played straight in Gin's route where Haru is the only person capable of replicating Aya's song.
• Broken Bird: Haru is though, edgy, and very fragile as a result of her childhood, when her grandmother, whom she lived with, passed away and her family began squabbling over the inheritance. After which, Haru dropped out of school, living on her on her own and arduously working part time jobs to pay bills. Meeting Aya made things better and she gave her hope through music, only to get worse again when Aya disappeared.
• Character Development: In Gin's route, Haru ultimately decides to trust in herself, believing in the faith that others put in her.
• Cutting Off the Branches: Failing to save Haru's life results in almost all of the branches being cut off. As in, all but two. One of the others is cut if you let Keisuke die, which, as said in his entry, is very easy. The one that remains is not a good one.
• Damsel in Distress: The target of multiple Escort Missions, and unlike the other named characters who are in such missions, she never joins as a party member. The fact she's suicidally depressed and the target of every demon in a twenty kilometer radius lowers survivability.
• Death Seeker: Keeping this woman alive is goddamned hard, she makes it harder. Her attempt at Suicide by Cop is just the tip of the iceberg: she's actively targeted by demons and the only means she has to "defend" herself are a broken sequencer and a total absence of the will to live.
• Demoted to Extra: A fairly major character throughout the story, especially in Gin's route, but only sneaks in a pair of optional cameos in the 8th Days.
• Diegetic Soundtrack Usage: Haru may sometimes be found performing "Reset", the game's main theme.
• Guide Dang It!: Easily the hardest major character to keep alive, due to her Death Seeker tendencies. Which sucks, because her ending is easily the most idealistic of the bunch.
• Happily Adopted: Aya found Haru when she have nowhere to go and brought her to Gin's bar. They even made a band together called D-Va.
• Idol Singer: You can't help but cheer for her, especially when she commits to completing Aya's song to save everyone.
• Impossibly Cool Clothes: That◊ dress◊ needs to be arrested for violating the law of gravity.
• It's All My Fault: She believes the demon invasion and the lockdown are all the result of her summoning demons about two months prior to the events of the game. You'll have to convince her that this isn't the case.
• Ms. Fanservice: Has a rather fanservice-y design as her dress exposes quite a bit of her body.
• Order Versus Chaos: Neutral-aligned.
• The Power of Rock: it's later revealed that the first song she ever composed is the key to getting rid of the demons in Tokyo.
• Save This Person, Save the World: If you can't save Haru, you can't save the world, unless you Take a Third Option and use Atsuro's route.
• Security Blanket: Her sequencer, which Aya gave to her. She literally calls it a Security Blanket after you save her on the 1st day.
• Sexy Backless Outfit: It's more apparent in the manga, but Haru's dress exposes her back.
• Significant Green-Eyed Redhead: Incredibly important to the plot and her survival is key to most endings, but the only early clue you get of this is her eye-catching looks.
• Stepford Smiler: Acts like a cool, flirty, and devil-may-care character, but is actually suicidally depressed and a Death Seeker.
• Suicide by Cop: On the fourth day, unless you talk her out of it.
• The Tease: Flirts with the main character quite a bit. Even moreso if you respond in kind.
• Took a Level in Cheerfulness: A major point of Gin's route is Haru coming to terms with Aya's loss, and ultimately deciding to move on.
• Vapor Wear: A dress that looks like it should be causing a wardrobe malfunction every time she so much as turns her head, and which very obviously has nothing underneath it.
• You Are Better Than You Think You Are: She has a crippling lack of self-confidence and multiple times you can let her know that she really is a great singer, a good songwriter and, most important, a good person.

Commander Fushimi

Commander Fushimi

Voiced by: Atsushi Ono (JP), Patrick Seitz (EN)

Another member of the Japan Special Defense Forces who is absolutely dedicated to ensuring the lockdown is a complete success and Izuna's Commanding Officer during the Tokyo Lockdown.

---

• Badass Normal: Enters the lockdown knowing full well how bad the situation is and how little time he has to make things right.
• Did You Just Flip Off Cthulhu?: In Yuzu's 8th Day, he outright tells the angels to screw off when he's attempting to take Naoya into custody and declares that the government has cut its ties with the angels, fully knowing just how insignificant he is compared to them.
• Heroic Sacrifice: Almost. He entered the lockdown knowing there was a very high chance of dying by the hands of the government, and he is seen defending civilians from demons without a COMP on his own. In some endings, the demons disappear just before he's overwhelmed by them. One second later...
• No Full Name Given: Unlike many of the other human charcters, his given name is never stated.
• Reasonable Authority Figure: His ultimate goal is to ensure the best for Japan; and he is perfectly willing to assist a bunch of teenagers when they obviously are more qualified to achieve this than him.

Yasuyuki Honda

Yasuyuki Honda

Voiced by: Kenjiro Tsuda (JP), Kirk Thornton (EN)

An office worker who was caught inside the lockdown and is desperate to escape for pressing personal reasons. Normally quite calm and collected; though said personal reasons cause him considerable stress, he keeps it to himself.

---

• Anti-Villain: Even when he goes off the deep-end in some routes, it's really hard not to feel for the guy.
• Corrupt Corporate Executive: Implied to be working for some, as the entire reason he was caught in the lockdown was because he was sent to steal a COMP. Honda treats this as 'just doing my job', so it's unclear where he stands...
• Deal with the Devil: In the final battle with Belberith during Yuzu's 8th day, Belberith gives him a contract with Baphomet. It fully restores his living party members' HP and MP after his every battle.
• Despair Event Horizon: Discovering that his son is dead in the Escape ending.
• Determinator: This man wanted to escape the lockdown so bad he was willing to attempt taking on demons, angels, and the SDF, as he was NOT going to be barred from being by his hospitalized son's side.
• Dual Boss: In Naoya's 8th Day, he ends up teaming up with Loki of all people. Loki promised him he'd bring his son back to life.
• Establishing Character Moment: Has his personality properly established on Day 2 after your first battle alongside him. He explains that he has a son having an operation outside the lockdown and that he needs to escape in order to be by his side, then toys with the idea of using his COMP to force his way past the blockade. This shows his primary motivation and the seeds of the darker sides he shows later in the game.
• From Nobody to Nightmare: Starts out an ordinary Salaryman, steals a COMP and begins to use its power to defend himself and smack down ordinary humans, and becomes a villain in Yuzu's ending.
• I Did What I Had to Do: Took the COMP-stealing job to pay medical expenses; later justifies siccing his demons on normal humans by stating "They attacked first. They deserve it."
• Last-Name Basis: He's primarily refered to by his surname Honda.
• Odd Friendship: He is a Salaryman who ends up befriending the delinquent Kaido. However, he downplays this and claims that they are more teammates than friends.
• Outliving One's Offspring: In Yuzu's 7th day and Amane and Naoya's 8th days, it's revealed that his son died on the table. In Amane's route, he breaks; in Yuzu and Naoya's routes, he snaps.
• Papa Wolf: He's incredibly devoted to his son and will risk life, limb, and his morals in order to be by his side.
• Roaring Rampage of Revenge: In Yuzu's 8th Day. After failing to get there in time for his son's operation and being made aware of his death, he utterly snaps and blames the SDF for preventing him from being there, prompting him to mercilessly kill them for revenge.
• Slasher Smile: In the Escape ending, following his breakdown.
• The Stoic: Starts out as one; gradually gets worn down by stress and strain over the course of the lockdown.
• Those Two Guys: He spends the first few days of the lockdown working with Kaido most of the time.
• Tragic Villain: He's an ordinary office worker who is trapped in the lockdown, resorts to increasingly immoral measures to escape and reunite with his beloved son, and goes completely off the deep end when he is unable to make it home before his son dies.
• Unlucky Everydude: Honda, for all intents and purposes, is an entirely normal man who is seriously dealt a bad hand by the events of the game.
• What Happened to the Mouse?: His plot thread is never resolved on Gin or Atsuro's routes. In the original release, it's the same story on Naoya and Amane's routes, but he does return on the 8th day and receives proper closure there.
• You Have Outlived Your Usefulness: In the final battle with Belberith on Yuzu's 8th day, after both Baphomet and Honda are defeated, Belberith kills him. If Honda is bypassed altogether, Belberith absorbs Honda into his body when he reaches 1 HP, healing him to half health.

Shoji

Shoji

Voiced by: Akeno Watanabe (JP), Tara Platt (EN)

An Intrepid Reporter investigating the 'Tokyo Lockdown' on her own, hoping to uncover the truth behind what's going on. Can be a good source of information, due to this.

---

• Badass Normal: She's one of the few characters to not have a comp, but she manages to survive all 7/8 days in the lockdown without a scratch on her and manages to gather as much information as the party does despite the increasing Ax Craziness of demon tamers with every passing day. And unlike Fushimi, she doesn't have military training or a firearm with her. She also frequently keeps up with the information you can gain from sources like Izuna... despite not having the same reputation that let you speak to her. She's a good journalist indeed.
• Intrepid Reporter: She claims to be made of win herself.
• Mr. Exposition: Her mission inside the lockdown is figuring out what's going on behind the scenes. Luckily, she freely shares with you the information she gathered, though as the days pass you may be able to figure out things before she does. When you first meet her, she also explains the mechanics behind the social unrest inside the lockdown and how the government is trying to keep control over the situation, but how they will ultimately fail.
• No Full Name Given: One of the few human characters who only has one name stated. It's not made clear whether Shoji is her given name or surname.
• Permanently Missable Content: Talking to her on the 8th Days whenever you have the chance does NOT produce anything productive. You literally skip time with her, and skipping time in the 8th Days may cause you to lose additional plot-important events or lose characters from joining back into the group when you had the chance to speak with them instead of her. However, talking with her gives some funny lines.

Gigolo

Gigolo

Voiced by; Yuji Ueda (JP), Hiroki Takahashi (drama CD), Vic Mignogna (EN)

The Casanova that pops up from time to time to provide helpful amounts of exposition when he feels like it. He has some history with Naoya and is incredibly knowledgeable on the history of the demonic world and the Throne of Bel. His name is unknown ("???"), so he is identified by his dialogue boxes as "Gigolo".

---

• Doppelgänger Spin: When you fight him in Yuzu's route, he creates duplicates of himself to confuse you. It also occurs during an optional fight on Naoya's 8th day.
• Dual Boss: Depending on the circumstances, he may team up with either Naoya or Honda.
• Enigmatic Minion: You spend a good deal of the game having no idea who he is, what he's doing inside the lockdown, and what his link with Naoya is.
• For the Evulz:
  • Yes, destroying Beldr needed to be done to save the world. Doesn't change the fact that he only told you how to do it because he felt like screwing over Beldr. Again.
  • He does it again in Naoya's 8th Day, where he'll tell Honda that he can bring his son back to life if he helps him kill the Overlord.
• Informed Ability: Despite his title, we don't really ever see him act like a gigolo of any sort, unless you count moderately flirty dialogue with the protagonist.
• I Shall Taunt You: He has insulting dialogue for every playable character when they fight him; sometimes humorous, sometimes making a fair point.
• Mr. Exposition: He gives a lot of info about the Bels and their goals/backstory ingame. He's also the one who who talks about the Multiple Endings, while mentioning their good and bad points.
• No Name Given: Marked as "???" on the map, though his dialogue boxes identify him as "Gigolo".
• Purple Is Powerful: Looks rather flamboyant in his purple suit, which certainly makes him stand out of the crowd. And rightfully so, since he's none other than Loki, a very powerful demon indeed.
• Sharp-Dressed Man: Purple suit, dark pinstripe shirt, and a rather unusual yet very stylish tie. A big contrast with the suits the various office workers wear, too.
• Stealth Mentor: He explains the situation with the Bels, tells you about the Devil's Fuge (indirectly saving your life), and explains the different paths and their outcomes near the end of the game. And while he pretends everything he does is because it amuses him, he gives the Player Character one hell of a What the Hell, Hero? if you decide to listen to Yuzu and run away from your responsibilities, disregarding all his good advice in the process. The fact that you can fuse him after you defeat him can be interpreted as a his way of giving you even more help to not screw things up in your New Game Plus.
• Trickster God: He's revealed to be the god of tricks, Loki.
• Wild Card: He bounces around between helping and hindering you on a whim.

Aya

Aya

Former lead singer of D-Va, Haru's mentor, and Gin's lover. Currently studying music overseas. At least, that's what Gin told Haru to keep her from worrying.

---

• Chekhov M.I.A.: It's mentioned early in the game that she is missing and nobody knows what happened to her. She doesn't actually return, but much later in the game she does play a big role in figuring out how the demon summoning server works and how the effect can be reversed.
• Hope Bringer: Aya was revealed as this to Eiji and Haru, bringing a sense of purpose and belonging to their previously aimless and depressed lives. Both hit the Despair Event Horizon and believed life had no meaning anymore after Aya's disappearance.
• The Lost Lenore: To Gin.
• Love Redeems: Her relationship with Eiji turned him from a self-absorbed delinquent to a mature Big Brother Mentor.
• Meaningful Name: She's Haru's teacher. Haru is often seen performing the game's main theme, Reset. The artist of Reset is named Aya Ishihara.
• Posthumous Character: She's been dead and/or "absorbed into the demon world" since before the game began.
• The Power of Rock: Her songs prove key to the demon summoning program and potentially getting rid of them.

Shomonkai Founder (UNMARKED SPOILERS)

Shomonkai Founder

Voiced by: Jamieson Price (EN)

The founder and leader of the Shomonkai cult. A fervent worshipper of the Shomonkai's god.

---

• Archnemesis Dad: On Amane and Gin's routes, Amane turns against him.
• The Bad Guy Wins: Happens on Yuzu's Day 8; when you confront him, he admits he has gotten everything he ever wanted and more after humanity rejects God of its own free will.
• Bitch in Sheep's Clothing: The Shomonkai initially come across as a benevolent organization, especially since the member you interact with the most is Amane. In reality, the Shomonkai are the ones most responsible for causing the lockdown to begin with. It's telling that both the Law and Chaos representatives—Naoya and Amane—turn against them.
• Deal with the Devil: He cuts a deal with Belberith to summon him to the human world in exchange for his aid in fighting God.
• The Dragon: He's the main human enforcer of Belberith's will in the human world.
• No Name Given: He is only ever referred to as the Founder. Although given that he's Amane's father, his surname is "Kuzuryu".
• Pet the Dog: At the end of Yuzu's Day 8, since he's already won, he disbands the Shomonkai and surrenders without any further violence.
• Posthumous Villain Victory: On Naoya's route, although he and Belberith don't live to see it, his actions create a powerful champion to stand against God (that's you). On Naoya's good Day 8, humanity turns against God as well, which would have greatly pleased him.
• Rage Against the Heavens: His goal is to free humanity from God's influence, and he will do anything to see that happen.
• The Reveal: The Shomonkai's god, also known as "His Majesty," is in fact Belberith.
• Suspiciously Similar Substitute: Not the Founder in particular, but the Shomonkai quite clearly invoke the aesthetic of the Messians from the early Shin Megami Tensei games, being a group of cloak-wearing worshippers who fervently worship their god and provide safety to ordinary people. Except it turns out that the Shomonkai don't worship God, but instead Belberith.
• Visionary Villain: His sole objective is to use demonic power to defeat God. Turning humanity against Him works too.
• Well-Intentioned Extremist: In the end, he is fighting to save humanity from God's Ordeal and Judgment. Unfortunately, what he unleashed was worse.

Azuma

Azuma

Voiced by: Tomoyuki Higuchi (JP), Dave B. Mitchell (EN)

An important figure in the Shomonkai. Tall, dark, and mysterious. Also helped cause Aya's disappearance, has designs on Haru, happens to be selling COMPs on the side for a tidy profit... And isn't as smart or untouchable as he thinks he is.

---

• Badass Boast: Immediately subverted right after delivery.
• Badass Long Robe: Azuma's battle sprite sports a long robe complete with Dramatic Wind.
• Heel–Face Turn: In both of Naoya's 8th Days, where he'll either oppose or aid the protagonist depending on his choices.
• Karma Houdini: Despite handing out the COMPs to further corrupt Tokyo and his attempted murder of Gin, he is an ally in both Naoya's and Amane's 8th Day. Averted in Yuzu's 8th Day, where he is arrested after being defeated.
• No Full Name Given: One of a few human characters who only has one name stated.
• Oh, Crap!: After realizing Gin's COMP can actually hurt him. And so can yours. Hilariously pointed out in Overclocked where his voice starts to whimper out of fear.
• Smug Snake: Believes himself to be a Magnificent Bastard, but his usual calm and arrogant behavior are quickly thrown out of the window when he finds out that Naoya basically trolled him and the entire Shomonkai by disabling the COMP's safety mode, enabling it to damage high ranking Shomonkai members such as Azuma himself.

Remiel

Remiel

An angel that is possessing Amane willingly and is sealing away Jezebel to prevent her from devouring Amane's soul. He desires for the Hero to become the Messiah in order to end the lockdown and guide mankind to salvation.

---

• Beware the Nice Ones: Despite being the kindest of the angels, he's also the one responsible for calling God's Thunder if humanity fails the Ordeal.
• Demonic Possession: With consent from his host Amane.
• Godzilla Threshold: In Naoya's 8th day. His disappearance is because he was preparing God's Thunder, an attack summed up by Atsuro as "the Final Option up to a million", because you repeatedly rejected his guidance. At this point, Remiel really isn't in a position to take a more merciful option.
• Knight Templar: Subverted. He is the only angel in the game (and nearly the entire series) who wants to save all humans. Even those that are considered irredeemable. For this, the other angels think he's soft.
• Meaningful Name: Mercy of God/Compassion of God. Fitting for an angel who wanted mercy to be shown to mankind and wants to help humanity.
• Only Sane Man: The only angel who doesn't see mankind as being irredeemable and doesn't act Holier Than Thou.
• Our Angels Are Different: The Winged Humanoid type, and possesses Amane willingly to keep Jezebel from devouring her soul.
• Sealed Evil in a Duel: Is keeping Jezebel sealed within Amane to prevent her from devouring Amane's soul, though it's a losing battle and she'll eventually be freed.
• Token Good Teammate: Amongst the Heavenly Host. Unlike the rest of the angels, who are aggressive, veering into hostile if you don't agree with them 100%, Remiel just wants to help, even when he believes people are beyond help.

Wendigo

A roaming demon who appears in the Yamanote Loop. He is the being destined to kill the Protagonist, Atsuro and Yuzu. But they aren't going to just give up...

---

• Bigfoot, Sasquatch, and Yeti: He's referred to as a "snowman" by the Laplace Mail. He's an abominable snowman, alright.
• Screw Destiny: You're not supposed to beat him, you're supposed to die. But the game is called Devil Survivor.
• Small Role, Big Impact: Objectively, he's just a demon who's a bit out of your league. But the fact that you don't die when you're supposed to triggers the first breakdowns in the Laplace Mail and sets your party on the road to encountering Beldr, and thus the plot. Your first encounter with him also brings you into contact with Amane.
• Wake-Up Call Boss: While this is telegraphed in advance, he's the boss who reminds you that you're in an Atlus game. He's Level 17, while your party are probably under 10. If you don't grind a bit first, crack some skills, and exploit his weakness to fire, you're not going to change your destiny.

Bel Demons

Bel Demons

Powerful Demons that contain either the essence or are pieces of King of Bel. They now wage war against each other except for Belberith, Jezebel, and Belzaboul in order to claim the Throne of Bel. The current Demons in the war for the Throne of Bel are Beldr, Belial, Jezebel, Belzaboul, Belberith, and the Protagonist (Abel). Another Bel, but not fighting for the Throne, is Babel, which serves the King of Bel and will fight against the one who becomes victorious to prove they are worthy of being King of Bel.

• Achilles' Heel: Beldr is a stand-in for Baldr. Beldr's made a contract with the very planet, so everything on it has agreed not to harm him, meaning he's invincible. Well, there is one thing that didn't enter the contract... devil's fuge, i.e. mistletoe. And before you get any ideas, he nulls everything but devil's fuge. Even Almighty, which can pierce any other protection.
• Adaptational Villainy: While all of the other Bels are known as malevolent demons in Abrahamic myth, Beldr is a chief heroic deity of the Norse Parthenon. In here, he's associated with the malevolent deities in Abrahamic lore.
• Back from the Dead: Each Bel does this for the Boss Rush. Not to mention Beldr and Belial will appear in the Overlord 8th Days after being summoned by the Protagonist against Metatron. Beldr also returned from the dead on the 3rd Day.
• Barrier Change Boss: The final boss Babel; luckily, the weaknesses are automatically given and you should be able to kill it quickly before it changes the second time. Ironically, that's the only annoying part, as you will most likely be using non elemental spells (though bringing Elec Dance to abuse the first weakness it picks up isn't a bad idea).
• Biblical Bad Guy: All of them except for Beldr, the protagonist, and technically Babel. If a certain path is chosen, that can apply to the protagonist too.
• Big Bad: No matter which route you pick, Belberith provides the most immediate threat and is the Hero's primary competition for the Throne of Bel.
• Big Bad Wannabe: Beldr and Belial are on their own in trying to become King of Bel, but stand no chance against Belberith.
• Body of Bodies: All the Bels defeated by Belberith make up his body and their hatred for God fused with his.
• Boss Rush: In Amane and Naoya's routes, all the former Bels return after being summoned by Babel.
• Clipped-Wing Angel: In Gin's route, Babel's second form is actually weaker than the first, to compensate for the fact that you don't have any demons to fight it with.
• Co-Dragons: Jezebel, Azuma, the Founder, and Belzaboul are this for Belberith. Belzaboul is also The Dragon for his true master Lucifer.
• Demonic Possession: Jezebel does this to Amane.
• Dual Boss: Beldr and Belial in the Boss Rush. Azuma and Belzaboul plus Honda and Belberith are one in Yuzu's 8th Day.
• Elemental Powers: Each of them has at least one elemental spell.
  • Belberith has Mabufudyne and Maziodyne, although he gives up the former during the Boss Rush.
  • Belzaboul has Mazandyne
  • Belial and Jezebel have Maragidyne. Beldr had the Lost Flame skill but loses it during the Boss Rush.
• Evil Cannot Comprehend Good: Belberith cannot understand why you would become the Messiah and servant of God.
• Eviler than Thou: Regardless of which route the player decides to pick, Belberith is quite clearly the nastiest one involved in the events of the lockdown. Given the context of Megami Tensei settings, that's definitely saying something.
• Face Full of Alien Wing-Wong: Belzaboul's strategy mostly consists of planting his spawn in your bodies, which burst out and become full grown flies. Meaning Belzaboul is a giant demonic Bot Fly.
• Fallen Hero: Beldr was once a benevolent god, but is now determined to spread sorrow on Earth until everything cries since he was trapped in the underworld when a hag refused to weep for him.
• Final Boss: Babel is the last opponent for all routes except Yuzu's.
• Gods Need Prayer Badly: It's implied that it works for all demons (and angels), but Belberith is profiting from it the most: as more and more people start following the Shomonkai and the longer the lockdown stays in effect, the more power he gains.
• Graceful Loser:
  • When you defeat him, Belial congratulates you and comments that humans are more qualified for the Throne of Bel than demons are.
  • When you go down the Overlord route, Belberith is most pleased with the idea of fusing with you, since you will continue the war against God. Subverted with the other routes, where he is less than pleased with you defeating him and doing something like becoming the Messiah.
• Humans Are Cthulhu: When defeated, Belial comments how humans have much higher ability to harness the power of Bel than demons do.
• Knight of Cerebus: The invincible Beldr's sudden arrival is the point where the game's plot really goes into overdrive.
• Lethal Lava Land: Jezebel's stage inside Amane's soul, until you do enough damage to set Amane free.
• Life Drain: Beldr does this with his Vampire Mist skill.
• Nigh-Invulnerability: Beldr can't be hurt by anything except the Devil's Fuge. Not even Piercing physical attacks or Almighty attacks will scratch him.
• One-Winged Angel: Babel transforms into a demonic tower after you defeat the first form.
• Pre-Final Boss: Belberith in the original Devil Survivor is fought immediately before Babel in all routes except for Yuzu's. Subverted in Overclocked where Amane's and Naoya's routes have an eighth day.
• Rage Against the Heavens: As they contain the hatred for God that the original King of Bel had, they all want this to some degree. Especially Belberith, who is made up of many Bels and thus has their hatred of God as well. Subverted depending on which path the Protagonist takes. Also subverted with Belzaboul, who doesn't care at all about the war of Bel and is only participating because his master Lucifer told him to serve Belberith.
• Readings Are Off the Scale: Their HP and MP are simply shown as "???", although their respective bar meters (indicating percentage of each stat) will still function as usual.
• Rule of Symbolism: There are Seven Days in the Lockdown and there are Seven Bels in the game.
• Punch-Clock Villain: Belzaboul isn't actually aligned with Belberith or the other Bel demons - He's just there because Lucifer ordered him to help Belberith become the King of Bel.
• Sealed Evil in a Can: Remiel is keeping Jezebel sealed inside Amane. Though it's a losing battle and she'll eventually gain the upper hand.
• Shows Damage: Babel's first form starts to shiver and convulse once its HP drop below about a third.
• Skippable Boss: If Haru has died, Belial will not come out into the open to take her. This is a bad thing, as it means that you don't have the chance to prove yourself to Remiel or Naoya, locking you out of their routes as well as Gin's.
• Spell My Name With An S: Invoked with a few of the demons to make sure that there's a "bel" in there somewhere. One presumes that this game's incarnations of Baal, Bael, Belphegor, and Pabilsbag were also subject to this treatment. Fusing a Berserker will have it question if it's going to become Bel-Zerker, implying demons that gain the power of Bel work it into their name somewhere.
• Stars Are Souls: The form the original Bels pieces took before they became deities.
• The Starscream: Belberith plans to take down Lucifer when he's done with God.
• Taken for Granite: Beldr's Stone + passive skill can inflict this.
• Theme Naming: Their names all contain Bel.
• There Can Be Only One:
  • The party gets embroiled in the contest between the Bels for the Throne of Bel. The winner gets God-like power, and it turns out that the Protagonist is in the running.
  • Baal, Bael, Belphegor, and Pabilsbag were all defeated and absorbed by Belberith before the story began. On Atsuro's route, Belberith also absorbs Jezebel.
• This Cannot Be!: Beldr's death quote.
• True Final Boss: Belberith for Yuzu's path in Overclocked.
• Undying Loyalty: Although it does want the Protagonist to become Overlord, Babel is loyal to him once it is defeated and follows his will obediently. It will even return to the Demon World along with all demons or become a tool that he can use as the Messiah without question.
• The Unfought: On Atsuro's route, Belberith absorbs Jezebel before the party can confront her, adding to the sense of urgency.

Okuninushi

Okuninushi

The creator deity of Japan. Refuses to abdicate his nation to control of the King of Bel unless he can live up to his challenge: redeeming Cain, the first murderer.

• Back from the Dead: Is revived by his mother, Sasukuni-wakahime, every time he's slain in battle using the ability Mother's Warmth.
• Big Bad: Of Amane's eighth day.
• Break Them by Talking: Even after beating him for the third time, Okuninushi isn't truly defeated. He only relents when he sees that Cain has genuinely changed, and that the protagonist truly is Messiah.
• Cain and Abel: In his backstory, he is the Abel to his brother's Cain.
• Came Back Strong: Becomes stronger with each resurrection.
• Cherry Blossoms: Appear whenever he's talking or using his powers. He can also make them actually blossom on trees as well.
• "Get Back Here!" Boss: Spawns at a different location after each revival.
• Graceful Loser: Once he sees that Naoya's changed, even if it was a tiny almost insignificant change that's described as a droplet in thousand-year-old ice that was believed unchangeable, he abdicates the rule of Japan to the Messiah and commands all his follower demons to heed him as the Messiah.
• Knight Templar: Would rather destroy Japan and create it anew than let it fall to control of the Angels, when he abdicated his rule in the past in order to let mankind rule itself and not be governed by a higher power.
• "Not So Different" Remark: Inverted. Naoya claims that, since Okuninushi fled from his assault while Abel died and ascended as a Bel demon, he is more deserving to rule Japan than Okuninushi. Borders on Insane Troll Logic since Okuninushi was only able to flee after being killed several times and revived, while Abel was never revived after being killed once.
• Order Versus Chaos: He defines Neutrality in this game, though he will only act to oppose Law's victory.
• The Power of Love: His mother's love revives and strengthens him during the battle. On top of the speculation by the party that Susano-o went to Honda since he longed to see a loved one, and it becomes implied that Okuninushi also wished for Honda to be reunited with his son since he's the one who sent Susano-o to him.
• Super-Empowering: Bestows power upon Tamers in the lockdown who seek to escape. In Honda's case, he even sends him Susano-o so he can meet his son.
• Super Special Move: His attack Anchor/Godly Whip, which hits all the characters on the field with Almighty damage, keeps getting stronger version as the fight progresses.
• Took a Level in Badass: In most games, he's a mid-game demon. Here? He's a True Final Boss who lives up to what we all expect of Atlus.
• True Final Boss: Of Amane's route.

Metatron

Metatron

The angel who serves as the Voice of God.

• Adaptational Heroism: He's noticably more moderate than usual for the franchise. His truly nasty side only really comes out if you turn against God or run from the ordeal, and Gin and Atsuro's endings see him let you off with nothing more than a stern warning not to abuse your new power.
• Knight Templar: In Naoya's 8th Day, he has no concern for the human cost of bringing down the Overlord and establishing God's control over humanity.
• Mouth of Sauron: He speaks for God, who stays off-screen for this game.
• Order Versus Chaos: The leader of the forces of Order.
• Reasonable Authority Figure: So long as you don't rebel against God or otherwise fail the Ordeal, he's willing to respect whatever decision you make regarding Babel and the demons.
• Screw This, I'm Outta Here: In Overclocked, under two separate circumstances.
  • On Naoya's 8th Day, he flees when the Overlord awakens to his power as King of Bel and freely summons minor demons and resurrects two Bels to attack him; he wisely chooses to flee for the moment.
  • On Yuzu's 8th Day, like the rest of the Angels he abandons humanity.
• True Final Boss: In Naoya's 8th Day.
• Worthy Opponent: In Naoya's 7th Day, he is very respectful to the protagonist. He explains the ramifications of the new King of Bel's choice, states that they're now enemies, and encourages him to follow the path he has chosen to the end until one of them wins out.

Lucifer

Lucifer

The ruler of demonkind and arch-enemy of God.

• Armor-Piercing Attack: Lucifer possesses Pierce in his first phase, so his attacks go through all defenses except for Repel. He loses it in subsequent phases.
• Badass Bystander: Lucifer is a powerful figure who could have deeply influenced the war between Bel demons and the lockdown of the city... but he has no interest in the Throne of Bel, only sending Belzeboul to assist Belberith prior to the events of the game.
• Blood Knight: Lucifer really only descends and calls the protagonist to face him in battle because of this.
• The Computer Is a Cheating Bastard: Possesses Dragon Eye passive for his second and third phase, which allows him to move three times per skirmish, and that's assuming he doesn't get an extra turn (which would result in another triple move). Though the chance is small, this means he can cast three Megidolaons in a row to devastate entire parties, especially on higher difficulties.
• Evil Laugh: While his dialogues are in normal text, Lucifer's only voice lines in the game are menacing laughters or sinister chuckles at different intonations and volume, and he laughs each time his dialogue comes up.
• Greater-Scope Villain: Lucifer is only peripherally involved in the events of the game. His contribution was ordering Belzaboul to support Belberith; otherwise, he's mostly there to watch the show.
• Increasingly Lethal Enemy: In his second phase and onwards, he begins using Megidoladyne, an extremely powerful Almighty attack which hits every friendly party in the map and gets 50% stronger each time he casts it. It is a spell which he uses outside of skirmishes, and he will use it until it reaches 4-digit damage per target in a game where player characters and their demons can each only have 999 HP.
• Life Drain: Crosses with Mana Drain. One of Lucifer's attacks in his third phase is Drain, which takes away HP and MP from your entire party to restore his. Given he moves three times per skirmish, the fact multiple casts of Drain can cripple the party makes his battle even more luck-based than it already is.
• Luke, I Am Your Father: Despite poetically describing the Protagonist as both son of God (for being Abel) and a child of man, Lucifer also proclaims himself as Abel's true father, the one who is watching over his future. How true this is or what it really means if true is not known.
• Shock and Awe: His preferred elemental spell, being available in all three of his phases. Lucifer also drains Zio spells once he enters third phase.
• Superboss: Fighting him is completely optional, and extremely difficult.
