Video Game / Devil Survivor 2
All the stars in the sky are (Not) our enemy

The darkly prospering days of man have reached an end.
You who have strayed from the cycle of the stars will leave not a trace of your existence.
But fear not. You will no longer feel anything...
Quote from the Game Over screen

Devil Survivor 2 is the sequel to the Shin Megami Tensei spinoff game Devil Survivor, developed by Atlus. It released in Japan on July 2011 and in North America on February 28, 2012.

20 Minutes into the Future, three Ordinary High School Students are heading home after a mock exam. They simultaneously receive a phone message from Nicaea, a "dead face delivery site" (in beta). The attached video shows a subway accident killing all three of them.

And then an earthquake derails the oncoming subway car.

Before the train hits them, Nicaea offers the students a chance to change their fate by becoming demon tamers. They agree, and after being saved by (and subduing) demons that appear from their phones, the trio return to the streets of Tokyo to find Earth is under attack by extraterrestrial invaders called the Septentriones. Opposing the aliens is JP's, (Japan Meteorological Agency, Prescribed Geomagnetism Research Department), whose charismatic leader enlists their aid but also knows more about what's going on than he should.

Devil Survivor 2 expands on the first game's demon roster and grants a second level to their racial skills. Like the Social Link system in Persona 3 and Persona 4, the new Fate relationship system grants allies bonuses and unlocks new demons as your friendship deepens.

In 2013 Devil Survivor 2 received an animated adaptation. Tropes from the anime can be found here.

Devil Survivor 2: Record Breaker is an enhanced 3DS port of DeSu2. In addition to a complete voiceover of the original game, it adds a new story arc with a second set of alien invaders, a new cast member named Miyako Hotsuin, and (Japan only) a crossover where Durarara!! characters cameo as demons.

Compare and contrast Neon Genesis Evangelion.Seriously! 

The Devil Survivor 2 games provide examples of:

    open/close all folders 

    General Tropes 
  • Akashic Records: And they are extremely important to the storyline!
  • All There in the Manual: The art book has a lot of supplemental information about the characters, such as their heights, birthdays/star signs, where they want to travel, etc., and even goes as far as to mention that Yamato has a younger twin sister named Miyako (as far as the original game goes, she is nonexistent... but she appears in the Updated Re-release).
    • That last bit is an odd detail, because when this is brought up to Yamato in Record Breaker's Triangulum arc, Yamato says that he knows every member of the Hotsuin family and—at least in the world where the main party originated—there is no one named "Miyako" in the family.
    • The game assumes you played the previous game, therefore assuming you know how the demon summoning program works.
  • Ambidextrous Sprite: Fumi's dress and Makoto's badge.
    • Also notable in Record Breaker during the boy's physicals, where Jungo and Daichi are wearing shirts with letters on them. Whenever they're on the left side of the screen, the letters are reversed.
  • Anyone Can Die: Like the first game, but worse. At least one Fate character dies in every ending. Roughly 2/3 of the cast can die, although the game forces you to start saving people after three deaths, to ensure you have a decent roster by the end. At worst, five main characters can die by the end of the game.
  • Badass Crew: One mission will have you characters form three of these, and depending on route the Meritocracy, Egilitarian, or Fixed factions will all have one, with the route your main character is on having the most badass of them all at his beck and call.
  • Badass Longcoat: Yamato and Fumi. A few others have their own but don't wear it. In fact, a LOT of characters wear these.
  • Biodata: Everything is stored as data within the Akashic Record. Including a personas death and the world itself. The Administrator has the power to delete the world or rewrite it using the Akashic Records.
  • Bland-Name Product: A ruined "Sterbacks" can be seen in Shibuya, and Yuzuru is apparently a reader of "Shoji Leap". And Daichi is into "Aberzombie" apparel. And Joe got scammed into buying an "Armanyo" suit.
    • however, this is what proves that the suit is a bootleg Armani knockoff, so it's something more of an aversion.
    • While Io is looking for books, you can ask her if she's looking for "Shonen Chump".
    • A complete list of these can be found here, though in Japanese.
  • The Blank: Generic JP's members are drawn without a face for a literal version of Faceless Goons. However, they have a face in universe.
  • Blatant Lies: Grimehkala says something good will happen if you physically attack him. He repels physical attacks.
    • Ghost Q as well.
    Ghost Q: "Let's have a fair, one-on-one fight!"
    *Ghost Q summons a bunch of demons to gang up on MC*
  • Brainwashing for the Greater Good: Yamato's endgame plan is to convince Polaris to change human nature to be purely meritocractic. Ronaldo, listening in, proposes his own version of the same plan, substituting merit with egalitarian.
  • Broken Masquerade: The demons are everywhere this time. Covering them up has become impossible.
  • But Thou Must!: Interestingly, usually this is just the game getting you to stop joking around.
    • Averted in the first battle. You can choose to die, automatically getting a mission fail.
  • Butt-Monkey: Daichi. You can get him to man up eventually... or keep picking on him instead.
    • The Septentrione Dubhe. Let's see. He clumsily falls over when Daichi pulls the truck away, he looks like a giant (explosive) alien ice cream, and he gets recycled into a flunky by later Septentriones.
    • Kama also suffers a lot of abuse during the fourth day.
  • The Computer Is a Cheating Bastard: Aside from combos on CP demons and humans that would be ridiculous to get, the computer enjoys finding lone characters then juggling them with a ranged demon. A few enemies even get unmentioned buffs such as anti-almighty, or making Strong reduce attacks to 75% damage instead of 50%.
    • The Bonus Boss of the Triangulum Arc can freely resummon demons into the party as soon as you engage them, in case you had the idea of first picking off their companions to remove the damage reduction on the party leader.
  • Curtains Match the Window: Common among the cast, much like it was before. Our hero is one of the few exceptions; while he doesn't have blue hair, he has very striking blue eyes.
  • Deal with the Devil: A website Nicaea, rumored to show images of someone dying in the future, is much more than just that. Anybody who uses the website can form a contract and gain the ability to summon demons and cast spells through their phones.
  • Death's Hourglass: The Death Clocks and Laplace Mail have been replaced by Nicaea, a website that is able to predict how people will die, but without specifying when or where, which is relevant to the plot many times.
  • Deconstruction: Like the first game, this game takes every trope Pokémon plays straight and tears them apart. This time, you see first-hand the consequences of a failed demon contract, with a named character no less.
  • Did You Just Punch Out Cthulhu?: Your party fights demons with no weapons. High strength characters are punching gods, demons, aliens and literal Lovecraftian entities with bare hands.
  • Diegetic Interface: The various menu functions are presented as apps on the protagonist's phone. Furthermore, the user interface of the Demon Summoning App is shown to look just like the game's top screen, and characters even explicitly refer to names and skills shown there at certain points.
  • Dysfunction Junction: The majority of the cast has a tragic back story of some sort. And those who don't tend to have awful things happen to them throughout the story. There are a handful of characters that have generally happy back stories, like Otome who has recently adopted a daughter. But those can be even more tragic if you really think into it, because now Otome's adopted daughter has to live in a destroyed world.
  • Eastern Zodiac: The demons unlocked through fate and the characters personalities tend to correspond with the Chinese Zodiac. Airi for example unlocks Sheep themed demons and Daichi unlocks Monkeys. The only exception being the Anguished One.
  • Eleventh Hour Ranger: The Anguished One/Alcor
  • Even the Guys Want Him: One can make a case for both Yamato and Anguished One liking the Protagonist this way.
  • Eyeless Face: The random mooks from JP's are rendered this way.
  • Everything Fades: Even in cutscenes, whenever someone dies, they disappear.
  • Face of a Thug: Keita, who looks like the previous game's Kaido with light blue hair. Surprisingly, other than him being a bit too rash about things and eager to fight the demons, he isn't that much of a bad guy. To a lesser extent, Jungo.
  • Family-Unfriendly Death: Several; the first notable one is the train crash on the very first day, complete with shots of bloody corpses strewn all over the place. The Nicaea videos provide more of these examples.
  • Fanservice: It's a world where most women are incredibly stacked and suggestively dressed. Even the most conservative outfit on a female character is entirely formfitting.
  • Fantasy Kitchen Sink: A staple of the franchise. You'll summon up gods from every mythological pantheon that you can name along with ancient heroes, Goetic demons, Urban Legends, and horrors from beyond the stars.
  • Foreshadowing: The theme that plays when the protagonist is registering for Nicaea (which is where you give the protagonist his name) is the Anguished One's Leitmotif. Turns out the Anguished One is the one who made the site.
  • Game Play And Story Segregation: Pretty much all of the characters, if you develop fate with them, have a conversation in which they experience some sort of Character Development, but the apparent changes do not carry into main story sequences. Ronaldo and Makoto are hit particularly hard by this.
  • Handy Remote Control: Practically every weird piece of technology or magic in the game is controllable by cell phone.
  • Improbable Age: At a mere 17 years, Yamato serves as the director and leader of JP's. Partly Justified with the explanation that command of the group has been passed down through his family for generations, and they were the ones who founded it. And then deconstructed when it turns out that being treated as an adult from the day of his birth has prevented him from developing a concept of compassion, effectively rendering a low-key sociopath.
    • Likewise, Otome is a practicing physician at only 24. Not impossible (in Japan, anyway), just unlikely. Fumi is also...some kind of scientist at an age (21) when most people probably haven't finished their undergrad degrees yet.
  • Landmarking the Hidden Base: The JP's Tokyo headquarters are located under the Tokyo Diet Building, while their HQ's in Osaka and Nagoya are beneath the Tsuutenkaku and Nagoya TV Towers.
  • Leaked Experience: Leaders not present in the battle get 80% of what the MC gains (which can be boosted with Watchful and Vigilant). Demons with the latter two skills also get Leaked Experience. On New Game+, it's actually more efficient (especially with the EXP cap removed) to solo as much of game as possible with the MC's team. note 
  • Ley Line: The Dragon Stream.
  • Life Drain: The Life Drain skill. Drain does it as well as stealing MP, and Bonus Boss Alice uses a powered up version called Vitality Drain. Which drains HP from every enemy within a range of six.
  • Lighter and Softer: Unlike the first game, the characters are not locked in one city, so the claustrophobic atmosphere and more explicit decay of society into anarchy are missing. Compounding this is the increase in comic relief scenes and the Fate System allowing for rather sweet and happy moments. The reason for this is that the characters are living comfortably within JP's headquarters and not on the streets. Where the chaos is spreading and affecting the normal civilians who attack JP's in order to get supplies so that they can survive.
    • Even the covers for the game get in on this. Devil Survivor was dark red and black with the characters illuminated by reddish light. Devil Survivor 2 is blue and white with the characters illuminated by white light and the main character stretching out his hand like a savior.
  • Literally Shattered Lives: Several times, you'll see some poor human get hit with a blast of ice magic, topple over and shatter. Ouch.
    • Most notably seen with Merak's Circumpolarity Signature Move in the opening of the battle against him.
    • You also see a variation of this with fire turning someone to a figure made of ashes that crumble and blow away in Joe's death clip.
  • Love Potion: Charm inflicts this. Lilith's boss battle has all the other enemies on the field be men she's cast a spell over and her racial skill Temptation inflicts this on men, women, and demons.
  • Magikarp Power: Daichi's stat growth doesn't give him particularly impressive Strength or Magic, making him much less desirable in the first days, where most of the battles are about dishing out as much damage in one blow as possible. Crack Multi-Hit and Multi-Strike, though, and his above-average Agility lets him plow through anything that isn't immune to Physical attacks (though arguably Keita does the same job but better, and Hinako has almost exactly the same stat growth but slightly more fragile).
  • Medium Awareness: Justified when characters can see the enemy's name and skills, as several shots show the Demon Summoning App is basically the same as the DS's top screen.
    Jack Frost:"Gree-heetings from the bottom screen!"
  • Meaningful Name:
    • "The Septentriones" is the Latin name for the seven stars of the Big Dipper (literally, the "seven threshing oxen"), also lending its meaning to a Latin word for "north". They are individually named after each star in the asterism, which is used as a whole as a guide to find Polaris, the north star. And yes, you can look them all up on The Other Wiki.
    • Al Saiduq is also this; it's a slightly different spelling of Al Saidak, which literally means "the test", which is also another name for Alcor, a star system gravitationally bound to the Big Dipper star Mirak. He is the eighth member of the Septentriones, and the only one that is not overtly and immediately antagonistic.
  • Monumental Damage: Plenty of Japanese landmarks either get wrecked or are shown-to-be-wrecked over the course of the games.
  • My Rules Are Not Your Rules: Drain functions differently in battles between NPCs, not actually draining anything.
  • Mythology Gag: Bonus Boss Alice is found in Roppongi.
    • Bonus Boss Belial is fought in Bugeikan Stage.
    • Black Frost appearance in the game is one big reference to the first Devil Survivor. His compendium info even states he is powerful enough to become the Overlord!
    • Joe mentions he's a fan of a Featherman Manga.
    • Nitta is a character and Shijima is a reason from Nocturne.
    • The melody that Trumpeter plays on its horn is a segment of the Law theme from the first SMT game.
    • "Calm down" is the most common response for the Protagonist, with "Calm down, everyone!" being a Crowning Moment of Awesome.
    • In the artbooks Otome mentions that Koharu wants to go to Destiny Land.
    • Record Breaker adds a few to the anime:
      • Lucifer's design has been switched to his angelic Helel form.
      • Satan can now only be created by fusing together Nebiros and Zaou-Gongen, the same combination Yamato used during the anime's final battle.
  • New Game+: You earn titles based on your accomplishments in the game. Each title is worth a certain amount of points that you can use to buy the right to carry over demons, skills, money, the demon compendium, and auction ratings, remove the fusion limit and EXP limit, unlock Mitama fusion, and to buy the right to battle bonus bosses. Previously unlocked demons stay unlocked, and titles carry over from one replay to the next without having to be re-won.
  • Nice Hat: Yuzuru's flat cap (overlapping with the rest of his attire), Airi's white pillbox hat, and Jungo's black bucket hat much like Atsuro's hat in the last game.
  • Nintendo Hard: Ziodyne and Anti-Phys on Day 3 for a miniboss?! OH SHI-
  • Non Standard Game Over: If you choose to die rather than live at the beginning of the game. Worth trying at least once to see Tico's dumbfounded reaction.
  • Obvious Beta: In-Universe example. The Nicaea app is supposed to be in beta, in the same sense as Google Beta. By the Triangulum Arc, however, it's been upgraded to version 2.0.
  • Obviously Evil: Subverted. The sprite used for all police officers is downright diabolical looking, with red eyes shaded by a rakishly titled cap and a sneering grin. You don't encounter any actually evil cops in the game; the art assets are just reused from the first game where you do.
  • O.O.C. Is Serious Business: Pretty much all of the characters, if you develop fate with them. Io expresses her true thoughts, Daichi gets over his cowardice and attacks demons voluntarily, Joe foreswears being late ever again, Keita saves his teammates, and Fumi stops her experiments to save Jungo (or Daichi)'s life.
  • Post-Modern Magik: Traditional demon summoning rituals are transformed into a cell phone app.
  • The Power of Friendship: Similar to social links in Persona 3 and Persona 4, this game will have the 'Fate System' which allows you to form bonds with other Devil Messengers, which in turn helps them unlock new elemental strengths, special abilities, and new demons.
    • Also, only characters with at least Stage 4 Fate will agree to rejoin you in the final day except Yamato or Ronaldo if you pick one of their opposing sides or Alcor's route, but you can have them both in Daichi's routes. Ronaldo even ends up helping you persuade Yamato into joining you.
    • Mentioned word for word during the final battle with Polaris during Ronaldo's route.
  • Punny Name: In the manga adaptation, the main character is given the name Hiro Kageyama.
  • Redemption Demotion: Io, Yamato, the Anguished One, and Miyako all have unique abilities when fought as bosses that they do not retain upon joining your party. Yamato's case is justified by the fact that he specifically lures you to a location where he can power up. The other three have no excuse.
  • Red Shirt Army: The gold-uniformed JP's members don't even have eyes in their facial portraits, so it should come as little surprise that they get killed by demons and Septentriones. This is deconstructed by how little their Social Darwinist Bad Boss cares. Yamato only cares about the successful; dead subordinates are incompetent ones.
  • Running Gag: A small one- When commencing battle, Joe is visibly and reliably the last of the group to take out his phone.
  • Scarf of Asskicking: Several members of the team wear these while kicking ass and taking names, such as Daichi.
  • Screw Destiny: A major plot point of the game is that the past and future are already written. However, you spend most of the game giving this concept the middle finger and saving people and reality itself from their so-called destiny.
  • Sequel Escalation: Overclocked additions included three new playable days and the most voice acting out of any Atlus title produced at the time. Record Breaker trumps this with the addition of an entirely new, seven day campaign.
  • Standard Status Effects: MegaTen mainstays are all here — poison, paralyze, stone (with physical/force insta-kills), charm, forget (block skill use), and curse (no heal). Alcor also has the unique "Ill-Starred" effect which adds damage to any attack against the target.
  • The Stoic: The main character. Unlike the previous game's hero, who could get pissed off/startled, DS2's rarely shows any emotion. Even his usual angry/battle-ready pose has the same neutral expression as his default pose.
  • Strategy RPG: Though it's a somewhat non-standard one. No weapons or armor. No shops (except for the Demon Auction). No items of any kind. No character classes (in their place, the various demon races that give them unique functions).
  • Stripperiffic:
  • Token Evil Teammate:
    • Alcor, though his values fall under different principles.
    • Yamato and Ronaldo fall under this better than Alcor does.
  • Token Mini-Moe: Airi.
  • Tokyo is the Center of the Universe:
    • Though in addition to Tokyo, you also get to visit Osaka and Nagoya. Sapporo and Fukuoka too.
    • Taken more literally in the Liberator ending where it's essentially all that remains of Earth and its landmasses, the rest of it taken up by the Void being replaced by an endless ocean.
  • Two Guys and a Girl: The protagonist, Daichi and Io. Sort of subverted by Joe, who joins the group not too long after they summon their demons, and acts as a fourth to the group even though he was mostly excluded in all the promotional material for the game. "Sort of" because he's not really a peer in their age group and isn't seen with them in the "true" ending.
  • Western Zodiac: Aside from the Main Character, the Anguished One, and the Ticos, an artbook have stated that each of the characters represent one of the twelve signs of the Zodiac. The elements of each sign with Electricity replacing earth usually shows up as a resistance for each character at Fate 1, though there are exceptions. Their birthdays also match their respective zodiac sign.
    • The characters gender is also determined by their sign. As positives are male and negatives are female.
    • The characters routes, with possibly the exception of Daichi's Liberator and the Anguished One's Kingmaker are based on the Qualities of their Star Signs. Daichi's is Fixed, Yamato is Mutable, Ronaldo is Cardinal, and the Anguished One possibly represents Rebirth since the world is remade.
    • As a side note, During the Faction Warfare, only Daichi's team has one of each elemental Zodiac sign
    • The Protagonist and Anguished One not having any zodiac signs themselves leads to fan speculation that they are the 13th Sign Ophiuchus. A long time later, it was revealed that the protagonist is actually Gemini, which would of course be the only sign there were two of. Anguished One was confirmed in the official artbook to be Ophiuchus.
  • World of Badass: Most humans who have latent spiritual power have access to summoning demons. However, even those that don't can at least fight demons to some degree (as opposed to the first game, where non-demon summoners were boned by default and the only reason demon summoners could fight back at an equal level is because of a special secondary function of the summoning program).
  • World of Buxom: Every playable female character is notably gifted. (Yes, including the Token Mini-Moe, who is average at worst.) However, this is only really true of their conversation portraits. All are more modestly drawn in the few video cut-scenes and in their battle sprites.

    Septentrione Arc 
  • Action Bomb: Dubhe, Alioth and Merak's spawn.
  • Anti-Frustration Feature: Did one of your characters knock out Io Nitta before they channeled Lugh, preventing you from unlocking the demon as a fusion? No need to worry, the character will simply get back up and channel Lugh, anyway, giving you an unavoidable chance to unlock him.
  • Apple of Discord: The possibility of having Polaris "rewrite" the world and influence the general mindset of humanity. As soon as Yamato announced his plans for a world based on meritocracy, the party fractures.
  • Ax-Crazy: Bifrons likes to kill humans. He'll always ask the Anguished One if he can kill any humans in sight. The only thing that keeps him in check is his master.
  • Back from the Dead: Nebiros brings back defeated demons using his Necromancy skill.
  • Bare Your Midriff: Turns out Kama just loves belly buttons.
  • Barrier Change Boss: Beelzebub changes his elemental resistances every turn.
  • Bittersweet Ending: Sure, the whole "creating a new world from scratch" ending resulting in what appears to be a world of Ghibli Hills is very heartwarming, but you're really going to miss Al Saiduq.
  • Bonus Boss: Belial, Nebiros, Lilith, Beelzebub, Sage of Time, and Alice are all NG+ bosses, with Alice being the ultimate boss of the game. Ghost Q and Billiken aren't mandatory in sense that if you spend your time elsewhere, you can skip fighting them, but the former expects you to fight him solo with the MC and the latter has several cutscenes dedicated to him. Beating all of them makes them fuseable, although you need to beat Alice to make Belial and Nebiros fusable.
  • Book Ends: The first battle and the last battle in the game take place at 12:30 Sunday and in two of the six endings the game ends at the same time and place the story began: in the subway just before the train crash.
  • Body Surf: Done by Bonus Boss Nebiros if there are any enemies left on the field, and if there's less than 3 demon teams on the field, he uses his turn to summon more.
  • Bread, Eggs, Breaded Eggs: In a conversation on the third day, Daichi says he feels like he's in an action movie. You can call it a horror movie instead, leading Daichi to wonder what is next: Vampires? Zombies? Vampire-zombies?
  • Call-Back: A very funny one at that. If you manage to defeat both Botis and Bifrons when you first fight them, you get Black Frost to fight you in the 8th Day in all routes except Alcor's. What happens when he moves cements a full Call-Back to Devil Survivor...
    Black Frost: The messenger of love and justice is here! Time for some magical punishment! ★
    Hiro: (Choosing first answer) Frosty!
    Black Frost: …Ho? What’re you saying, ho? You got me confused with somebody else!
    • The message you get from Nicaea after the credits upon clearing the Anguished One's route give another one to the first Devil Survivor.
      You now have a new world. Let's Survive.
  • The Capital of Brazil Is Buenos Aires: According to the game's artbook, Ronaldo is half Brazillian, but if you go through his route he'll occasionally greet you in Spanish.
    • He doesn't do any such thing in the Japanese version, though, so it's a Woolseyism.
  • Cell Phones Are Useless: Twice, both of which involve death videos for the person they're trying to reach. The first time makes sense, since Keita is too big of a jerkass to give his cell phone number to the other characters. The second, however, is Joe forgetting to charge his phone, knowing full well that a dead phone will almost certainly result in him dying.
  • Chekhov's Gun: A event with Joe has him and a NPC mention Billiken on day 2 as a doll and a God of Luck. Come day 6 and said doll is a boss.
  • A Child Shall Lead Them: In the Meritocracy route epilogue, the group of people earlier seen defending a little boy in one of Makoto's Fate events is being led by him, who the game still addresses as "Timid Boy".
  • Chirping Crickets: Happens twice in one scene, during an event to revive Kama.
    • Some of Joe's punny jokes give this reaction.
  • Co-Dragons: Botis and Bifrons both serve Alcor. Defeating both results in Black Frost taking their place in every route but Alcor's.
  • Copy Protection: If the copy protection flags get set off, then during the first boss fight (which starts off as an escape mission then turns into a battle), after the exit is closed off, the event that is supposed to weaken the currently unkillable boss doesn't happen, rendering the game unwinnable.
  • Creepy Doll: Billiken.
  • Defrosting The Ice Kings: Spend enough time with Yamato and Keita and they eventually come out as Jerks With Hearts of Gold.
  • Developers' Foresight: If there's a character that ends up dying and was relevant to another character's event, the game will simply have someone else in their place and yield different conversations.
  • Disk One Nuke: You can learn Ziodyne much earlier than the other -Dyne spells if you crack it from Botis should you choose to go after Fumi. You can also learn Agidyne earlier than the Ice and Force -Dyne spells if you can crack it from Bifrons should you choose to fight him.
  • Dissonant Serenity: The Septentriones' theme certainly gives off this vibe.
  • Dub Name Change: The races of the Septentriones were changed to Star for the english release. In the Japanese version their race names corresponded with their ancient Chinese name.
  • Early-Bird Boss: Botis, should you choose to fight him. Ziodyne and Shield All on Day 3? This Is Gonna Suck. Fortunately, his speed is so low your entire party will get several shots at him before he moves more than once, and with some planning you can easily remove all his Extra Turns to trick it into spending all of his MP while you whittle away its HP. Also becomes a Disc One Nuke if you manage to crack those two skills with a Joint Crack.
  • Everybody Lives: Implied in the hidden route's Restorer ending.
  • Even the Girls Want Her: Lilith's Temptation auto skill inflicts charm without fail on males and has a medium chance of working on females/demons.
  • Face Death with Dignity: Ghost Q and Botis on the last day if you didn't kill him earlier in the game when you beat them.
  • Fanservice: Unlike the vanilla version of the game, the 3DS version adds completely new suggestive portraits of the girls (sans Otome) in the 4th Day's Secret Garden event. The boys' event also get new portraits, except in theirs, they are all wearing simple T-shirts.
  • Failure-to-Save Murder: When you receive Keita's death clip, Joe notes that you could choose not to save him, but wonders if that might not be just as bad as killing him directly.
  • Faux Yay: You can suggest that Daichi pretends he's gay to lie about his attempted peeping.
    Daichi: Huh... I might get away with it if I said I was in love with Yamato. ...No. That's too risky. *sigh* I don't think I could keep that ruse up when I'm with the girls.
  • Foreshadowing: During Wednesday, Fumi calls the Protagonist and makes an off-hand comment about Joe asking her to use the Terminals to get to Timor and how the call was cut after he said that. This doubles as Gameplay and Story Integration when you do a quick check in your party menu and see that Joe is absent from your team. Later in the day, you find out he's the next one to die due to his phone running out of batteries and being unable to fight a horde of demons chasing people down.
  • Four Is Death: There are five admins mentioned in the story. Polaris is the fourth.
  • Gameplay and Story Integration: In the Turn Back the Clock ending, it is continuously stated that the protagonists will need a "strong willpower" to "keep their memories" after Polaris rewrites the world back at how it was before. Guess how the New Game+ mechanic works?
  • Gameplay and Story Segregation: During the fight with bonus boss Lilith you have to avoid defeating any of the men under her control or you'll kill them and fail the mission. No reason is ever given for why this differs from all of the fights with civilians or JP's members.
    • Most likely has to do with them being completely under her control. They are probably trying to fight you to the death. While everyone else fought in the game are in control besides Fumi.
  • "Get Back Here!" Boss: The fourth day's boss, in more ways than one. It's actually manifesting at several different areas around Japan, so your team has to split up to kill all parts of it simultaneously, plus once you fight it yourself, it keeps moving around the battlefield to evade your attacks. If it takes too long to kill it, game over!
  • Graceful Loser: Botis in the last day battle against him commends you on having great strength as he dies.
  • Gratuitous English: The e-mail message you get after the credits is in English even in the Japanese version.
  • Greed: Billiken's entire motivation during his battle where he hunts down anything that has macca and kills them to get it. If you don't have any he kills you anyway. Even other demons are terrified of him!
  • Hammerspace: Exactly where does Fumi keep all those laptops?!? She whacks Trumpeter with at least 7 to 10 of em! Her dress is way too small to hold em all...
  • Hand Wave: Explicitly done on more than one occasion by Yamato about how absurdly prepared JP's is.
    Daichi: An exclusive platform...!? Wait a sec, how is this place still running? I mean, after what happened to the subway...!
    Yamato: You're wasting time with these useless questions. Let's go.
  • A House Divided: By the final day, the party members that are still alive split into three distinct factions concerning what to do about Polaris, and allying yourself with one will cause the party members in the other two to turn against you. However, with the exceptions of Ronaldo and Yamato, you can convince them to rejoin you after the fights if their Fate is high enough. On a certain route you can even get those two to back you up.
  • Humans Are Cthulhu: One demon, Trumpeter, certainly feels this way after being mercilessly bludgeoned by Fumi.
    Trumpeter: "How do I put this... Humans have become such dreadful beings."
    • Taken literally in that our endless possibilities are able to defy even the fate determined by the Akashic Records, and ultimately Deconstructed when our relentless defiance of the Divine Order causes Canopus to register humanity as a virus in the Records.
  • I Just Want to Have Friends: Alice. Though all her friends are dead, so she respectfully requests that any candidates "Die for me!"
  • Ill Girl: Joe's girlfriend. Her condition is much worse than she lets on and she eventually dies. However, it seems as though she's brought back to life in the 'true' ending.
  • I'm Taking It Home With Me: Taken to some ludicrous extremes by a Badb Catha when you have to retrieve the pieces of Lugh's essence. If it gets to a piece first, it will squee like a little girl and directly mention this trope.
  • Indirect Kiss: On the first day, just before Dubhe's first appearance, Io gives Daichi her water bottle and he (somewhat terrified) notes she already drank from it. All three dialogue options from the main character allude to this trope.
    > No! Way!
    > Good for you, dude.
    > Lucky bastard.
  • Interface Spoiler: Even if you don't know the meaning behind the name "Septentriones", an in game event points out said invaders are all named after the stars in the Big Dipper, leading one to believe there will be seven major bosses across seven days. You might then notice the title logo and the file select screen both feature the Big Dipper as well as an eighth star, hinting that the game will not end after a week like the original Devil Survivor.
    • Another example would be the Fate System, it only applies to party members, but 3 members specifically are added to it and can even get a some ranks long before they join, those 3 being Yamato Hotsuin, Ronaldo Kuriki, and The Anguished One, Yamato and The Anguished One are both particularly bad for this since they don't join until the 7th Day at the earliest.
  • Invisible to Normals: Dera-deka says that you have to have at least some spiritual power already to access Nicaea.
  • Interrupted Suicide: Io is constantly afraid of offending anyone, so she always keeps her opinions to herself. However, this turns into an extreme where if you pick the wrong dialog choices, you could end killing her off several times within the storyline. Her main point of character development is when she finds a kid about to commit suicide because he's despairing over his lost family. Io, whose parents were also killed by demons, finally voices her opinion and convinces the kid to live on.
  • Irony: Abraxas is classified as a fallen demon yet Abraxas talks about repelling evil.
  • Just in Time / You Are Too Late: Whenever it comes to prevent a predicted death, you will either arrive just as things are getting grim, or immediately after the irreparable has happened. Even the first failed rescue mission is titled "Too Late".
  • Kill It with Fire: What Bifrons does to several JP's members and possibly Otome.
  • Lame Pun Reaction: If you pick Boo-njour! before the battle against Ghost Q, he'll say you make worse puns than he does.
  • Luck-Based Mission: The fight against Yamato. As usual for bosses, he gets an extra turn even while attacking from a range, moves insanely fast (though only two spaces at a time), and even if you can get close, there's a high chance that he'll use Megido twice in a row, which will kill pretty much anything. And of course no weaknesses and Reflect Phys. He also gets even faster as you defeat the demons around him, to the point where even ganging up on him can still end up with him having the faster turn. Even without the double Megido hanging above your head, he has Revive (Recarm on fallen allies at start of skirmish) and one of his demons has Samarecarm.
  • Make a Wish: Upon being defeated, Polaris will basically grant a wish to whoever defeated her. Each route involves the characters making a different wish. Unless you decide Murder Is the Best Solution.
  • Matryoshka Object: The materialized Dragon Stream, which is made up of a chain of heads linked by Nested Mouths. It Makes Sense in Context.
  • Mind Screw: Once the Akashic Records start being mentioned, the game then pulls an absurd number of Hand Waves. Said records are actually files for events given for any point in time, and said files have mostly nothing in them and the files with data in them are progressively being erased, which justifies why The Void exists. The records are ancient, and they have been known to record every point in history with incredible accuracy but the Septentriones are the guardians of these records and these records are acting like Laplace Mail in which they are both missing the files for future. However, anyone can give new data for these files, since these files can be edited by Polaris and anyone who controls it, which later becomes the goal for the heroes.
  • Mood Whiplash: In the Liberator ending, you get a nice somewhat melancholic piano melody that suddenly shifts to the battle theme when the credits roll.
    • And in the Chaos ending, the picture showing Yamato reigning over the world is a little less dramatic when you notice the protagonist and his bunny ears in the background.
  • Multiple Endings: Like the first game in the series, there are multiple routes. This time the routes include Ronaldo (Cardinal Ending), Yamato (Mutable Ending), Daichi (Fixed Ending, with three variations including the "True" Ending), and the Anguished One (a very strange ending that could be considered Rebirth). They also have different names each: the person you ally with, a type of star sign, and one of the names listed below. And since Daichi gets multiple endings, the "star sign" names are extended for him.
    • Liberator. The Kill Polaris Fixed ending is a Downer Ending. The good news is that NOTHING supernatural (good or bad) can ever screw with humanity ever again, and our fate is ours alone to decide. The bad news is that, besides the Void being replaced by ocean, none of the damage done by Polaris has been undone. That means central Tokyo is the only land that exists in the whole world, as over 99% of the Earth's topography is now gone forever.
    • Restorer. The Turn Back The Clock Fixed Ending has Polaris rewind time to slightly before the erasure of the world, effectively making the New Game+ an in story Justified Trope.
    • Triumphant. Either of the above endings with all the characters recruited except the Anguished One. The "True" ending is the Restorer + Triumphant ending and gives you a "Where Are They Now?" Epilogue. The heroes vow not to forget one another when the Reset Button is hit. Bits of their Character Development show. Daichi promises to become more mature. Io is bold enough to walk up to you and ask to hang out. Hinako and Airi are getting along well enough to put on a concert together. Keita—who's now a boxer of some renown—is helping Jungo sell chawanmushi. The fear that all the events may happen again is proven invalid when the Nicaea app says that its services are no longer needed and wishes you good luck.
    • Egalitarian. Ronaldo's Cardinal route involves the creation of a utopia where all men are equal. Polaris' powers accomplish this and the civilians, SDF, and JP's work together to rescue survivors and rebuild society. While the game says that the kind of utopia man dreamed about is created, it questions whether or not mankind can maintain its prosperity without a competitive spirit and the drive to excel. The only certainty is that the future is in the hands of the heroes.
    • Meritorious. Yamato's Mutable route culminates in the creation of a true meritocracy. Survival of the fittest rules supreme as the weak are oppressed by the strong, and Polaris points out that even Yamato and the Main Character's supremacy could be challenged at any time. On the other hand, creed, color, age and family ties are no longer a bar to individual progress. Those with natural talent or a willingness to improve themselves are rewarded without fail. Demons are also still around this new world. Meaning that humanity must also be careful of demons.
    • Kingmaker. The Anguished One's route has you defeating Polaris and having Alcor replace her as the world's administrator. The world is reborn with man deciding its fate. Alcor becomes God, but loses his physical form and though the heroes lose the ability to interact with him, they still feel his presence.
    • And the sequel goes with Merging the Branches: specifically Triumphant and Kingmaker, the two Silver Endings, into a single Golden Ending. Or so it seems at first, but things soon get more complicated...
  • No Endor Holocaust:
    • Subverted. Nobody dies when Alioth crashes into Sapporo. But that's because everyone is already dead.
    • Averted later when it's implied that there may have actually been survivors who were crushed by Alioth (and if any survived, the deadly toxins that flooded the entire city would ensure it wasn't for long). Yamato just lied so that everyone won't feel bad about leveling the city.
  • Noble Demon: Botis.
  • Noble Shoplifter: Done at one point by Daichi and again by Joe towards the beginning of the game. Unfortunately, given just how quickly civilization breaks down, this act quickly become good intentioned but fairly meaningless.
  • Not Evil, Just Misunderstood: The Anguished One. He feels that humans are too controlled and wishes to bring freedom back to the world. However, being that he is a Septentrione, he comes off as a villain, and in four of the five routes, you and your party kill him. However, on his route, he becomes the essence of the new world, and becomes a god that loves and respects humans.
  • One Extra Member: The Septentriones (septem = seven). There are eight of them. The eight one, Alcor, is the only one not presented as a mindless abomination. He is the true identity of the Anguished One. He is the one that created Nicaea so that humanity can fight their fate of being erased from existence. In one of the routes, he even become a party member.
  • The Only One Allowed to Defeat You: The protagonist and the others were going to be killed by a crashing train; in pops an Obariyon, who holds up the train and cheerily says, "No dying that way! I need to kill you!"
  • Order Versus Chaos:
    • Interesting not in the fact the themes are present, as they are a MegaTen mainstay, but in the portrayal which follows astrological star sign qualities (Cardinal v. Fixed v. Mutable) than the traditional split. Both the "Law" and "Chaos" factions rely on Polaris to brainwash humanity to follow their plans of perfect egalitarianism or a hierarchy based on social darwinism (a Chaos mainstay for the series), and Polaris seems to favor the "Chaos" faction more than the "Law" one. All three factions are presented as valid points of view but both "Law" and "Chaos" arguably have terrible spokespersons.
    • Oddly, though a possible Neutral/True Freedom/Chaos variant provided by the Anguished One is a weird mix of the freedom of Chaos and a entity who watches over us and will never interfere with us unlike past Law figures (and Polaris herself).
  • Parking Garage: A recurring random battle map, the site of a very violent confrontation with Jikokuten and the site of Dera-Deka's death.
  • The Peeping Tom: In the "Secret Garden" cutscene, Daichi and Joe decide to spy on the female cast members' physical exam. The main character can join them too, leading to an eavesdropped conversation of the girls comparing their "assets," and several minor What the Hell, Hero? moments later on.
  • Previous Player-Character Cameo: If you defeat Bifrons and Botis early then on every route except Alcor's he'll be replaced by the messenger of Love and Justice Black Frost.
  • Rage Against the Heavens: What Alcor's route boils down to: You overthrow the administrator of the world and create a new world without it.
  • Reset Button: In one of Daichi's endings, you make Polaris turn back time to before the invasion.
    • Not only that, but the whole purpose of the Septentriones are to destroy and recreate the world. They have apparently destroyed and recreated the world numerous times.
    • Oh. Bit like Kagutsuchi, then?
  • Screw This, I'm Outta Here!:
    • If you defeat all the demons before defeating Ghost Q he'll decide to run away and must be beaten before he escapes to unlock him.
    • This is also Kama's reaction to learning what the cast wants him to do.
  • Signature Style: Do the Septentrionnes design and nature seem familiar to you? None other that Mohiro Kitoh developed them!
  • Strength Equals Worthiness:
    • Beelzebub's entire reason for being a boss fight. He's heard great things about the Protagonist and has come to test that strength.
    • Belial and Nebiros pick the player characters to be Alice's friends because they are so strong that they are worthy of her friendship.
    • This is also how Alcor tends to test people's worth. Such as the last day battles against one of his three Dragons.
    • And of course, this trope is related to why Yamato takes a shine to the MC after the party beats Dubhe as well as why he fights the MC (to "wake him up") in routes other than his as well as why Defeat Means Friendship for him in Daichi's route. He did sincerely believe Might Makes Right, after all.
    • Finally, this is why Polaris serves as the Final Boss on routes where your goal isn't to kill her: to test your resolve to change the world.
  • Take a Third Option:
    • When pitted against the choice between Yamato's meritocracy and Ronaldo's egalitarianism, Daichi chooses to instead seek for an alternative solution that wouldn't harm anyone. And even though he doesn't have a clue on how to do it, he still convinces Hinako, Io, and Jungo if he's still alive to follow him.
    • Then, the Hero can further take a fourth option by not joining any group and convincing the Anguished One to overthrow Polaris.
  • Tempting Fate: On the first day, the main trio decides to walk Io home, having to go through Roppongi and Shiba Park. But hey, as Daichi notes, what's the worst that could happen? Well, Roppongi just so happens to be the place where Dubhe makes its entrance and starts killing people.
  • ˇThree Amigos!: Notable in that the Protagonist and Daichi didn't meet Io until the beginning of the game. In the "true" ending, it's hinted that this is their future as well.
  • Ungrateful Bastard: As soon as you beat Billiken, the demons he was attacking decide that he was on to something and proceed to attack you for your Macca.
  • Video Game Cruelty Potential:
    • It is entirely possible to allow certain members to die, and you may be tempted to do so just to avoid having to fight them later on.
    • Try telling Jungo when you meet him that you're a foe and not a friend. It's like kicking a puppy.
  • Wave Motion Gun:
  • Wham Shot: It's a very subtle moment, but there's a foreshadowing event that tells what's starting to happen to the world days after the disaster first took place. After beating Phecda on Tuesday, a look at the map of Japan shows that the island of Shikoku is almost gone from the map.
  • invoked What Do You Mean, It Wasn't Made on Drugs?: Joe likes to read a manga called Offside Goalie Masashi. But not only does Masachi not even know how to play the game and has a crippling fear of heights that keeps him from going to the World Cup by plane, but apparently, every goalie in Japan dies in a "graphic, page-spanning tragedy." The manga would easily border on Who Writes This Crap?! due to its really strange story.
  • Your Days Are Numbered: Every day starting on Sunday one Septentrione attacks Japan. Because the alien invaders are named after the stars in the Big Dipper constellation, Hinako speculates that there will be a total of seven Septentriones, with the attacks lasting a week. And according to Yamato the Septentriones have the ability to destroy the entire world.

    Triangulum Arc 

  • Amazing Technicolor Battlefield: The final boss battle has multiple ones, but special mention goes to the final one where you are practically floating above a universe made out of blue glowing shards of light.
  • Arbitrary Headcount Limit: Normally, every scene in the game has two character portraits talking to each other...except one of Fumi's Fate events where you can see three at once, all in the name of Rule of Funny.
  • Bag of Spilling: At the start of the arc, the party members are about level 20, which is at least 30 to 40 levels lower than they used to be at the end of the Sept. Arc. Daichi specifically notes feeling weaker compared to when they fought Polaris. Possibly averted with your demons, skill library and unlocked auction levels, as these can be carried over when you start the Triangulum Arc as part of New Game+.
  • Big Bad: The Triangulum, whose leader is Arcturus. Then you find out there's an even greater force behind them that will continue to make the same thing happen again and again.
  • Bizarre Alien Biology: Cor Caroli's main body. It's two faceless female naked bodies on top of each other, and one of them has Miyako's hair.
  • Bonus Boss: Through the rewards' menu, both Ticos serve as one in a New Game+ of Triangulum. They are both fought several times during the battle.
  • Brick Joke and Call-Back: This arc is positively brimming with these in regards to the original Septentrione Arc, particularly in Fate Events. There's plenty of fun to be had in this Updated Re-releasenote , but there's also some more serious elements recallednote 
  • Cassandra Truth: The Protagonist is initially the only one who remembers everything about the previous world and knows what happened. His prior knowledge clashes hard against the rest of the party who don't recall anything and don't believe him until he makes them remember.
  • Demonic Possession: This happens to the Protagonist to deal with Spica before it manages to reach the Sky Tower through the sea. The party summons Aramisaki to create a barrier to block its way. However, the possession is completely intentional and even allows you to flirt with the demon possessing the MC!
  • Disc-One Final Boss: Sorry, bucko. Defeating Arcturus is not the end yet.
  • Dreaming of Things to Come: Everyone but the Protagonist start having a strange dream where they are all killed by Arcturus on the third day. Once said day comes, it's revealed that it had already happened in a second world.
  • Earn Your Happy Ending: Technically, most of the main characters' dreams in the previous world are met here: Io is outspoken, Airi becomes a pianist and is able to make an idol group with Hinako, Tsundere Keita is close friends with Jungo, and Makoto was able to continue her dream as a synchronized swimmer though she willingly turned it down to join JP's.
  • Eldritch Abomination: The Triangulum. Then there's Miyako in her Cor Caroli guise who looks like two faceless female bodies on top of each other and surrounded by black-and-yellow striped panels with large lady hands, not to mention Canopus and its various parts.
  • Eleventh Hour Superpower: The Prime Factors massively improve the party's abilities just in time for the final showdown with Canopus. Heat boosts elemental damage, Gravity boosts Physical damage, Time boosts Almighty and Curse damage, and Space adds 4 to everyone's movement range.
  • Everybody's Dead, Dave: The nightmare sequence at the start of Wednesday concerning the aftermath of the battle against Arcturus. Only Yamato barely manages to survive thanks to Al Saiduq's intervention.
  • Gameplay and Story Integration: Al Saiduq tinkers with the Skill Crack ability to get skills from others to be able to take a hold of Canopus' four factors.
  • The Ghost: Er Rai is frequently talked about as the next Administrator after the Triangulum, but you never get to see him. It is hinted that he causes the world's destruction after the sacrificial method is chosen.
  • Happy Ending Override: After saving the world from being deleted at the hands of a group of Eldritch Abominations... the world is once again being threatened with deletion at the hands of another group of Eldritch Abominations.
  • Headbutting Heroes: Airi and Hinako are still prone to doing this even after becoming an idol group, though they both admit they are deathly honest with each other because that will always yield them good results.
  • Here We Go Again: And one ending takes this to Forever War levels.
  • Idol Singer: Ironically enough, Airi and Hinako end up forming a successful idol group known as AiHina☆☆ (pronounced "stars") in this world. Daichi, before regaining his memories, is a total Fanboy of them.
  • In Spite of a Nail: Despite all of the changes to the timeline, the third day of the crisis still ends with Ronaldo storming the Nagoya JP's branch. This time, however, you're on his side.
  • Interface Spoiler: Despite Miyako's repeated statements that Alcor and Yamato don't exist, the Fate menu shows two empty spots that aren't filled out after you gather everyone else.
  • It's Pronounced Tro-PAY: An early conversation with Daichi makes the Protagonist say the website Nicaea as "Nikaya", which is surely a reference to how players used to pronounce the website's name without a clear audible example.
  • Laser-Guided Amnesia: The characters lose their memories of the previous world after being reborn in the new one. They vaguely recall events or have deja vu until something important enough happens that makes them remember.
  • Lighter and Softer: Many of the Fate routes are funner and sillier than they were in the previous world, though some of them have the occasional dip in mood.
  • Lovecraft Lite: As it turns out, defeating Polaris caused the mind of the universe itself to decide humanity was an unacceptable error and start spawning new Administrators to invade, eliminate the problem, and take over...and in all endings, humanity fights off his legions and resets twice, with all but two endings actually resulting in he himself having to withdraw, and in the Record Breaker ending that's because humanity effectively ate him.
  • Merging the Branches: Takes place after an amalgam of the Kingmaker and Triumphant Restorer endings where Everybody Lives (which you couldn't accomplish in any of the original endings).
  • Multiple Endings: There are four endings in the game.
    • Downer Ending: The party, including Yamato, accept Miyako's offer to sacrifice themselves to save the world by making Alcor a rightful administrator with their Administrative Authority with the consequence of not being reborn themselves. This causes the world to regress one more time, but at the great cost of making humanity (or at least Japan) never try to prosper. Although Alcor watches over it, it all goes back to hell with another unknown alien threat that destroys everything and lets the Void consume humanity for good without a force retaliating for survival.
    • Guardian Ending: The Protagonist decides to become the human administrator of the world to keep it safe from other candidates for the Heavenly Throne.
    • Endless Battle Ending: The party decides to fight an endless struggle against all potential administrators every time the world is regressed until they are no more. The next time the world regresses, the protagonist and Daichi barely have time to leave the school building before an invasion occurs.
    • Record Breaker Ending: The Break Record ending sees that everyone truly gets the happy ending they deserve: Canopus, the admin of the Akashic Records and the one behind the entire mess, is gone for good, the world is once again reset, this time outside of the jurisdiction of the system, meaning there will be no more extraterrestrial invaders ever again, and even Al Saiduq and Miyako are reborn as humans, meaning that everyone survives to live for the future.
  • The Needs of the Many: Miyako's main method of saving people whenever they have the chance: sacrifice the few to save the many. This ideology is what makes the main party oppose her outlandish idea of using them all as sacrifice and her capture of Al Saiduq, who opposed her as well.
  • No Sense of Personal Space: After experiencing the Dying Dream, both Jungo and Ronaldo (especially the latter) get really close to Airi to voice out how relieved they are to see her alive and well before they regain their memories. Unfortunately, both forget about invading her personal bubble that they both get smacked with a Megaton Punch by her.
  • Not What It Looks Like
    • At the start of Wednesday, Miyako visits the protagonist in his room, supposedly to tell him about how the search for his friends goes. She ends the conversation by staring at his face at a quite close distance to make sure there are no "irregularities" and he has the option of staring back (or blowing in her face). Daichi and Io promptly walk in on them. The protagonist can either tell the truth, that she was simply reporting something to him, or confirm Daichi and Io's fears that Miyako spent the night in his room.
    • During one of Fumi's fate events, she tries to experiment on the protagonist and he has the option of letting her take his clothes off. Fumi being Fumi, she sees no objections and she sits on his lap, trying to figure out how to take his jacket off. Again, that's when Daichi and Io enter the scene.
  • Off Model: Although Miyako was designed by the same artist, her in-game artwork displays thicker outlines than the rest of the characters who have thinner outlines.
  • Order Versus Chaos: Order being represented by the Admins, Swords, and the Divine Order of the Universe, with humanity and Alcor as Chaos.
  • Plot Armor: Unlike the previous arc, it is quite impossible for any of the characters to permanently die as there are no events that require you to be there immediately to prevent deaths. This is pure Fridge Brilliance because Miyako wants to force the party to avoid confrontations that may kill them and jeopardize her plan to use them all as sacrifices to fix the problem with the Heavenly Throne.
  • Retcon
    • The arc starts with a combination of two endings that are physically impossible to obtain in the previous arc.
    • The world regression results in this on a mass scale that shows that the characters have truly developed to the point that their own history has changed. Koharu's parents live, Makoto avoids the accident that destroyed her career in swimming, Io has been friends with Daichi and the protagonist for a long time, etc. Things have changed so much for the better that it shows that the current threat is not the result of humanity being stagnant.
  • Ret Gone: Yamato has completely disappeared from existence in this arc's world, though the main party still remembers him and try to find out if he's still alive somewhere. He is, except he's not in their world.
  • Running Gag: The Protagonist's choice to insist Miyako is Yamato wearing a drag.
  • The Reveal: Those dying dreams everyone but the Protagonist have had? It's not quite prophetic, but it's actually a dream of a second world previous to the one the arc starts at. It reveals the world had been regressed twice, not once. For that matter, the reason why the Protagonist isn't in them is because he performed a Heroic Sacrifice between the first and second worlds when Arcturus tried to consume Al Saiduq into the Void. His absence in the second world was what allowed Arcturus to exterminate everyone.
    • Why does Miyako but not Yamato exist? The truth is that Miyako is an alien replacement for Yamato in the third world while he himself is hiding and working at a higher plane of existence to keep the Protagonist alive by fixing his data.
  • Rule 63: With Yamato gone from existence, the Protagonist can ask Miyako multiple times if she's Yamato wearing a drag.
  • Putting the Band Back Together: Much of the earlygame concerns the cast recovering their memories and rejoining the fight against the latest invaders, the Triangulum.
  • Shout-Out: Daichi playing a game called "Evil Beater" on a device that looks like a 3DS. The logo of the game, when looked from afar, resembles Devil Survivor Overclocked's title logo.
  • Senseless Sacrifice: If the player chooses to go along with Miyako's plan of sacrificing everyone, the ending shows that it is pointless. While the world is saved and Alcor becomes the new Administrator, he has to step down for the next Administrator, who decides to have the Void consume earth again because of humanity having no potential to progress. Sure, the party's sacrifice saved their world... but only for a while.
  • Single-Target Sexuality: Upon Miyako's introduction, Daichi can hardly stop thinking about her over another female party member. He doesn't even mind if she berates him and admits he likes this side of him.
  • ˇThree Amigos!: The main character, Daichi, and Io are this in the Triangulum world, having been friends with each other for a very long time.
  • Total Party Kill: In the second world, Arcturus utterly annihilates the entire party sans the Protagonist (who saved Al Saiduq from being consumed by the Void between worlds), and Al Saiduq who saved Yamato in time to regress everything a second time.
  • The Unfought: Canopus in case you agree with Miyako to sacrifice the whole party.
  • Unusually Uninteresting Sight: Nobody acts strangely around the violet policeman with pointed ears, but this is a world where government agents can summon demons.
  • What the Hell, Hero?:
    Dionysus: Aw... This really hurts. I mean, this cuts deep. *sigh* I suppose I'll just go then. I know when I'm not needed.
    • If you agree to Miyako's proposition that you all sacrifice yourselves to turn Alcor into an Administrator, Yamato will give you a rather brief one before going along with it.
    • The protagonist can call Miyako on eradicating Aramisaki in one blow. Exactly why she did that at all is not explained and comes across as jerkish.
  • Wistful Amnesia: In the Guardian ending the Protagonist, as the new Administrator, restores the world but erases his friends' memories of him, leading to Daichi, true to this trope's form, thinking he's forgotten something important when he and Io graduate from high school.
  • Zerg Rush: Not the phones gone berserk that call demons endlessly, but special mention goes to the one mission where an endless stream of JP's agents at the planetarium will continue to hunt you down until you make a gateway for the whole team.
