[[folder: Vali Team]]

An independent team led by the current White Dragon Emperor host, Vali Lucifer. Vali, and the companions who follow him, sided with Ophis' Khaos Brigade in the early story arcs on the promise that they would be granted the chance to battle powerful enemies; clashing with Issei's group several times. After the events of Volume 6, they have since broken off their partnership with the Khaos Brigade, and battle enemies alongside Issei and company.

!! Tropes relating to all of them:
* BadassCrew
* FiveManBand
** TheHero: Vali
** TheLancer: Bikou
** [[TheBigGuy The Big Girl]]: Kuroka
** TheSmartGuy: Arthur
** TheChick: Le Fay
** TeamPet: Fenrir and Gogmagog
* FriendlyEnemy: More to the Gremory team rather than TheAlliance (They ARE wanted terrorists after all).
* HeroOfAnotherStory: They have their own adventures as well as battles that they've fought. We have only seen one story from their perspective so far, while the rest have been through second-hand story telling.
* [[spoiler: ThePardon]]: [[spoiler: For their help against the Remnants of the Khaos Brigade, The Vali Team not only are allowed to join TheAlliance but are receive pardons for thier actions. This allows La Fay to make a Magician's Contract with Issei.]]
* RagtagBunchOfMisfits: Who, according to Issei, have nothing better to do.
* WalkingTheEarth

!! Vali Lucifer
->'''Species:''' Human/Devil Hybrid
->'''Voiced by:''' Creator/RyotaOhsaka

Current wielder of Divine Dividing, the Sacred Gear containing the White Dragon Albion, Vali is a warrior in the service of Azazel before defecting to the Khaos Brigade because peace is boring for him. He is also the great-grandson of the original Lucifer, but doesn't seem to care about that.
* TheAce: He's descended from the original Lucifer, and as such, he has enough magical power and potential to learn Norse magic by [[InstantExpert simply reading it]]. He's also extremely strong and can maintain Balance Breaker for months, according to Azazel. To top it off he could control and use Juggernaut Drive for a few minutes without losing control, making him a {{Foil}} to Issei.
* AchillesHeel: Like Issei, he's also weak to both anti-dragon and anti-devil attacks (former because he's, well, a dragon, and the latter is because he's a descendant of the original Lucifer).
* {{Badass}}
** BadassBookworm: He has just read through Norse magic in a day and suddenly is able to pull off those crazy moves.
*** InstantExpert
** BadassCreed: His new Juggernaut Drive chant, [[spoiler:[[UpToEleven Juggernaut Overdrive]].]]
--->[[spoiler:"I, who is about to awaken, am the White Dragon who will take the law down to the darkness. What we strengthen is the height of the Heavenly Dragon! The path we go is the road of the domination of the White Dragon! We stop the infinite and devour the dream! I walk the road of domination with infinite destruction and by piercing through the imaginary dream. I shall become a pure Emperor of White Dragon. And I shall have you obey the silver-white illusions and the perfect evil ways."]]
* BerserkButton: [[spoiler: He is ''utterly pissed'' when he sees his grandfather Rizevim Lucifer again]].
* BetterThanSex: He'd rather be fighting strong opponents than having sex and is definitely one of the few men in the series who's not a pervert.
* {{Bishonen}}
* BloodKnight: It's his lifelong goal, thus the peace between devils, fallen angels and angels doesn't sit too well for him.
* BornWinner: Just take a look at what ''he has''.
* CurbStompBattle: Delivers this to Kokabiel and [[spoiler:Pluto (via a RealityBreakingParadox)]].
* DefeatMeansFriendship: [[spoiler:How he got Juggernaut Overdrive. Rather than talking to the past possessors of Divine Dividing, he ''literally'' beats the crap out of them.]]
* EvilCounterpart: To Issei.
* {{Expy}}: He looks like [[VideoGame/TalesOfTheAbyss Guy Cecil]] or [[VideoGame/TalesOfVesperia Flynn Scifo]], and his White Dragon Emperor form resembles the [[CodeGeass Lancelot Albion]].
* {{Foil}}: To Issei -- he's talented, and said to be the strongest holder of Divine Dividing thus far, while Issei lacks any kind of talent and is said to be the weakest holder of Boasted Gear thus far. In terms of personality Vali [[BloodKnight is more interested in fighting]] just as Issei is [[LovableSexManiac towards sex]].
* IWasJustPassingThrough: His excuse for [[spoiler:rescuing Asia from the void. Turns out he was also trying to get Gogmagog, and just happened to see Asia.]]
* TheJuggernaut: He also has access to Juggernaut Drive, but it won't kill him because he can temporarily control it by consuming his vast magic reserves inherited from the original Lucifer.
* LightningBruiser
* NotDistractedByTheSexy: Always kept getting teased by Kuroka to make out with her already but rare bats an eye at her as much as he does any prospective opponent.
* ParentalAbandonment: Abandoned by his parents because they thought he was a real monster until he was raised by Azazel.
* ThePlan: Him helping out the Kuou group was because he wanted to take Fenrir. The group, however, just only needed his teeth, and yet he TookAThirdOption.
* TheRival: To Issei.
** PrivilegedRival: He's descended from the old Lucifer and is thus extremely magically talented. This contrasts with Issei's lack of talent in magic and his normal background.
* RivalsTeamUp: He and Issei teamed up against Loki.
* SuperPowerLottery: Won it big. Not only does he wield Divine Dividing, which can halve an opponent's power and add it to his own, but he also inherited the original Lucifer's massive reserves of magical energy, plus he has enough talent to learn most spells by just reading about them.
* VillainsOutShopping: Him and Bikou encounter Issei, congratulate him, and went to the ramen shop.
* WorfHadTheFlu: [[spoiler:Couldn't use Juggernaut Drive against Cao Cao because he was poisoned by an arrow coated with [[AchillesHeel Samael's blood.]]]]
* WorthyOpponent: He really sees Issei as this.

->'''Species:''' Nekomata
Koneko's older sister and also one of the most dangerous stray devils after killing her master. [[spoiler:Except it was an act of self-defense (both for her and Koneko) against their master, who experimented on various subjects before turning to them to become more powerful.]]
* BloodKnight
* BoobsOfSteel: Well, she's a nekomata and she did kill her former master in cold blood.
* CainAndAbel: [[spoiler:Except this time, Kuroka has a good reason to kill her and Koneko's master, even if this causes a rift between them.]]
* CatGirl
* [[spoiler:CoolBigSis: Not that she'll ever admit it.]]
* [[spoiler:FreudianExcuse: Her and Koneko's master was conducting experiments to make his team ''and'' his blood relatives stronger. When he turned to both of them, Kuroka's sisterly instincts kicked in.]]
* [[spoiler:InnocentCohabitation: She moves to the Hyodo Residence as a semi-permanent resident in Volume 14.]]
** [[spoiler:PrettyFreeloaders]]
* [[KnightTemplarBigBrother Knight Templar Big Sister]]: Just try harming Koneko in her presence.
* LightFeminineDarkFeminine: The dark to Le Fay and Koneko's light.
* MeaningfulName: Her name means "Black Song", referring to her hair color.
* OhCrap: When she fires a blast of senjutsu and youjutsu at Issei's newly-attained (and perfected) Balance Breaker and it didn't put a dent on his armor.
* SiblingYinYang: With Koneko. Their hair colors are even the exact opposites.
* [[spoiler:TakingTheBullet: Took Vali's blast which got reflected by Cao Cao going towards Koneko.]]
* TheTease: Often teases Issei every once in a while just to see her sister's reaction.
* VerbalTic: Ends her sentences with "nyan".

->'''Species:''' Monkey/Human Hybrid
A descendant of [[JourneyToTheWest Son Wukong]], he first appears in Volume 4 of the novels, picking up Vali who was about to release Juggernaut Mode against Issei.
* {{Bishonen}}: His human form in one of the short stories is quite the looker. [[ Just look.]]
* BloodKnight
* MeaningfulName: His name means "Beautiful Monkey". Given his human form in one of the short stories, it's pretty much justified.
* TheNicknamer: He's the one who gave Rias and Issei the nicknames "Switch Princess" and "Oppai Dragon", respectively.
* OhCrap: Whenever the original Son Wukong is mentioned. [[spoiler:[[CharlesAtlasSuperpower Given what we know about him when he made an appearance]]]], Bikou may have a point.
* {{Shapeshifter}}: Can assume human form.
* SimpleStaff: Well, he is using Son Wukong's staff after all.
* VillainsOutShopping: Him and Vali encounter Issei out in the night, congratulate him, see [[{{Gonk}} Mil-tan]] who they think is a nekomata, and go eat at a ramen shop.

!! Arthur Pendragon
->'''Species:''' Human
Arthur is the same-named descendant of [[KingArthur the legendary British warlord]] and wielder of the strongest piece of Excalibur, as well as Collbrande (Caliburn), the sword in the stone.

!! Le Fay Pendragon

!! Katerea Leviathan

One of the devils of the Old Satan Faction who attacked at the peace conference.
* CombatTentacles: Captures Azazel within one. He just ''hacks off his arm'' like it's nothing.
* FemmeFatale
* SpellMyNameWithAnS: Kateria, or Cattleya?

!!Cluzerei Asmodeus
The descendant of the original Asmodeus, he appears in the sixth volume to challenge Azazel, but is killed by Sirzechs.
* ArsGoetia
* WeHardlyKnewYe: The only reason why he even bothered showing up was that we get to see how powerful Sirzechs really is.

!! Shalba Beelzebub
The descendant of the original Beelzebub, he appears at the climax of the sixth volume to look at the failures of Diodora, thereby killing him.

[[spoiler: He comes back in Volume 11, all rebuilt but has lost most of his powers.]]
* ArsGoetia
* [[spoiler: HeroKiller: [[CombatPragmatist He did have to cheat for that one]] but he was able to ''kill [[OurHeroIsDead Issei!]]'' [[DeathIsCheap Of course, it just didn't stick.]]]]
* [[spoiler:KilledOffForReal: Finally dies at the hands of Issei, who unfortunately pulled off a TakingYouWithMe in return]]
* OhCrap: Scared shitless when [[spoiler:Issei in [[DeadlyUpgrade Juggernaut Drive]] was ''too powerful'' for him to take on.]]
* PutOnABus
** [[spoiler:TheBusCameBack: In Volume 11.]]
* [[spoiler:RoaringRampageOfRevenge: In Volume 11.]]
* SmugSnake: Is willing to flaunt his powers in front of everyone and keeps on declaring that he will make the other mythologies acknowledge that the devils are the strongest race of the entire world. And is even willing to kill children who do not agree with his ideologies. [[CurbStompBattle Three guesses what Issei did to him. Twice.]]
* [[spoiler: TakingYouWithMe: To Issei. [[OurHeroIsDead And he did.]]]]
* [[spoiler:WeCanRebuildHim: And that's what the Khaos Brigade did.]]
* YouHaveFailedMe: [[KickTheSonOfABitch Kills Diodora]] because of failing to kill Rias' group.


[[folder: Hero Faction]]

A dangerous faction consisting of human descendants of famous mythology characters led by Cao Cao. The heroes serve as the primary antagonists of the light novel's third saga; not only succeeding in draining Ophis of her power for the Khaos Brigade, but forming an alliance with the Death God, Hades, to end the world of devils.

!! Tropes relating to them:
* BadassNormal: They're humans who could die right off the bat from just about anybody from any mythology. They still kick ass.
* DeadlyUpgrade: Chaos Break, an injection that is capable of giving a massive power-up to humans at the cost of their bodies deteriorating to the point not even a phoenix tear can heal them.
* DealWithTheDevil: Made a deal with Hades to [[spoiler:acquire Samael, the Dragon Eater.]]
** ItOnlyWorksOnce
* FiveBadBand:
** TheLeader: Cao Cao
** TheDragon: Siegfried
** TheEvilGenius: Georg
** TheBrute: Heracles
** TheDarkChick: Jeanne
** TagalongKid: Leonardo
* HumansAreBastards: Definitely fits within the core group members.
* HumansAreSpecial: The only ones who could wield a Sacred Gear (and not artificial ones) are humans or former humans who either turned into angels or devils. Unfortunately, the Hero Faction are the villains for the third arc.
* KnightTemplar: They seem to genuinely believe that killing gods and monsters are for a good cause.
* [[spoiler:LikeABadassOutOfHell: This is what Indra taunts Cao Cao, Georg, and Leonardo to pull off only because Issei already did it before.]]
* [[NamedAfterSomebodyFamous Named AND Descended After Somebody Famous]]
* ShownTheirWork: In-universe at least.
* [[spoiler: UndyingLoyalty: When they're not BrainwashedAndCrazy, Cao Cao's willing to let other Sacred Gear human users join him for his cause. They do follow him all the way through to the end as shown by the {{Mook}} Issei encountered.]]
* TheUnfettered: Has shown to go absurb lengths to accomplish their goals.
* [[spoiler:UnwittingPawn: Gets suckered by Hades.]]
* WeakButSkilled: They're all this, but Cao Cao deserves a special mention because according to Vali, he could be the strongest human being thanks to his True Longinus.
* WellIntentionedExtremist: The only reason why they even formed the group was because the humans are the ones who get affected the most when three factions who have been going on a war with each other for a long time suddenly had a PeaceConference and created TheAlliance.
* WhatMeasureIsAMook: Sends a lot of {{Mooks}} towards the Occult Research Club to force them to reach Balance Breaker levels.

!! Cao Cao

Leader of the Hero Faction and a [[RomanceOfTheThreeKingdoms descendant of Cao Cao]]. He also wields the strongest Longinus, True Longinus.
* AffablyEvil
* AwesomenessByAnalysis: He beats his opponents by gathering intel on them and taking advantage of their weakpoints.
* {{Badass}}
** BadassNormal: He's just a normal human being who has a Sacred Gear and ''almost always dominates in fights.''
*** GlassCannon: All it takes to defeat him is just one hit from anybody in this series. Yet ''no one can land a hit on him.''
** OneManArmy: Oh is he ''ever''.
* BladeOnAStick: The True Longinus is the original spear that stabbed Jesus!
* BloodKnight: Clearly enjoys fighting tough opponents like Issei, but is more composed than other examples. Issei even compares him to a calmer version of Vali. [[spoiler: When one of the members of Khaos Brigade showed him of an alternate world at peace, he found it boring.]]
* CombatPragmatist: Encourages gathering information and fights extremely unfairly. [[spoiler:Best examplified during his fight with Vali and Issei's group. He used Samael's poison to take out Vali and attacks the weakest links of the group knowing that Issei would protect them which he did. He in a instant he got rid of the two fighters that actually was a threat to him and weakened the other side immensely]].
* DangerouslyGenreSavvy: He'll study his enemies and perfect his style before even thinking of attacking his enemies.
* {{Expy}}: Other people in his group refer to him as the modern-day Cao Cao.
* [[spoiler:EyeScream: Issei manages to destroy one of Cao Cao's eyes, forcing him to use Medusa's eyes as a replacement.]]
* {{Foil}}: To Issei; both have companions who are willing to join the both of them, but while Issei, a devil, will not sacrifice anybody for his cause and does care for the well-being of other people, Cao Cao, a human, is willing to make sacrifices for his cause.
* HoistByHisOwnPetard: He was so CrazyPrepared that he neglected the fact that [[spoiler:Samael's poison also works on snakes because of his Medusa eye. Yeah, that same Samael blood that Issei got coated with in his [[CurbStompBattle fight against Shalba.]]]]
** {{Irony}}: He even lampshades it.
* [[spoiler: IdiotBall: He just had to hold it before Issei fires off that Switch Princess button, even noting that Issei was acting out of character.]]
* MagneticHero: Despite the fact that he'll employ brainwashing for the humans with Sacred Gears who aren't willing to join his cause, there are also people who are willing to join him because he's accepted them and will die for them.
* OhCrap: [[spoiler:After seeing Rias get summoned instead of Great Red.]]
* SuperpowerLottery: He won it by being the current wielder of the strongest Longinus.
** SphereOfPower: The True Longinus' Balance Breaker, Polar Night Longinus Chakra Valdine has SEVEN of them, each with a different power and name.
*** AttackReflector: Mala Nitana
*** BreakableWeapons: Chatsuka Ratana. It broke Durandal!
*** Flight: Hatsutei Ratana
*** KiAttacks: Balaniyaka Ratana
*** PowerNullifier: Itsutei Ratana, fortunately it only works on women.
*** SummonMagic: Kahabatei Ratana
*** TeleportersAndTransporters: Atsusa Ratana.
* ThisCannotBe: [[spoiler:After True Longinus refuses to activate its Truth Idea towards Issei.]]
* WorthyOpponent: He praises both Issei and Kiba for being able to at least match him and tells the both of them to get stronger. He also thinks of Vali as such as well because the last time they fought, it was exhilarating.

!! Georg

A descendant of [[{{Faust}} Georg Faust]] who made a contract with [[DealWithTheDevil Mephistopheles]]. He also wields Dimension Lost, one of the four most powerful Longinus to exist.
* AlternateDimension: Capable of sending people to other dimensions.
* OhCrap: [[spoiler:Taunting Gasper that Issei died in vain [[BewareTheNiceOnes wasn't really a good idea.]]]]
* SpecsOfAwesome: Shown in volume 12.
* SuperPowerLottery: Dimension Lost is one of the 4 top Longinus for a reason.

!! Siegfried

One of the top two swordsmen of the Khaos Brigade faction (the other is Arthur). His Sacred Gear is "Twice Critical", the same Sacred Gear Raynare thought that Issei had.
* BlessedWithSuck: Rather badly too. His Sacred Gear is Twice Critical which comes from dragons while Gram is a ''dragon killer''. You can see where this is going if he tries combining the two.
* DualWielding: Triple wielding, ''all the way to sextuplet wielding''.
* [[spoiler:HoistByHisOwnPetard: He gets killed by Kiba after Gram answered to Kiba instead of him.]]
* MasterSwordsman: Took on both Kiba and Xenovia ''and won'' when they fought the first time.
* OhCrap: [[spoiler:When realizing that Rias' breasts ''are the breasts of miracles'' if combined with Issei's powers.]]
* RedBaron: "Chaos Edge" Sieg.
* ThisCannotBe: [[spoiler:When Gram chooses Kiba as its master instead of him.]]
* WeCanRuleTogether: Offers Ajuka to fight against Sirzechs since he's the only one who could put up a fight with the latter. His answer? [[spoiler:Wipe out ''all the devils'' that were present ''without even standing up.'']]

!! Jeanne

A human being who inherited the spirit of JoanOfArc and is also the wielder of the Sacred Gear, Blade Blacksmith which is a holy sword version of Kiba's Sword Birth.
* DeadlyUpgrade: [[spoiler:Injected herself with ''two'' Chaos Breaks when injecting with one was already deadly to begin with. She still gets curb stomped by Issei who at this point doesn't even have his Evil Pieces inside of him.]]
* InstantAwesomeJustAddDragons: Her Balance Breaker allows her to summon a dragon made up of swords.

!! Heracles

A human being who also has embodied the spirit of the hero, Heracles.
* HonorBeforeReason: [[spoiler:He threw away his Chaos Break injection at the last minute and decided to take on Sairaorg man-to-man. Needless to say, it doesn't work although Sairaorg was impressed with him.]]
* IShallTauntYou: The reason why he and Saji fought in Volume 12.
* KickThemWhileTheyAreDown: [[spoiler:Stomps Sona on the ground when she and her group were trying to defend a bus full of kids.]]
* OhCrap: [[spoiler:As soon as he finds out that Sairaorg didn't even have a scratch when he used his Sacred Gear at full power.]]
* ProjectileSpell: His Balance Breaker, Detonation Mighty Comet, makes him fire magic missiles at his opponents.

!! Leonardo

A boy who also has possession of the Longinus, Annihilation Maker and is also a descendant of LeonardoDaVinci[[note]][[InternetBackdraft and we'll leave it at that.]][[/note]].
* [[spoiler:DistressedDude: Gets captured by a newly rebuilt Shalba Beelzebub.]]
** [[spoiler:BrainwashedAndCrazy: Gets subjected by this.]]
* ShoutOut: The monsters he summoned in volume 11 were called [[Literature/AlicesAdventuresInWonderland Bandersnatch and Jabberwocky.]]
* SummonMagic: Annihilation Maker's main purpose is to be able to summon any monster.
** YourMindMakesItReal
* SuperPowerLottery: When you think about it the ability to summon a creature that can kill god is pretty amazing.


[[folder: Magician Faction]]

A faction of mages who were expelled by the Magician's Council, and allied themselves with the Khaos Brigade. They are introduced attacking the peace conference in Volume 4, but aren't seen again until post Volume 12 under the title, "Hexennacht," and fight alongside the newly established Qlippoth faction.

!! Walburga

A powerful mage who has possession of the Longinus, Incinerate Anthem. She is introduced in Volume 17 battling alongside Qlippoth's Evil Dragons against Issei and company.
* BloodKnight: Enjoys killing her enemies.
* PlayingWithFire: Basically a fire-mage thanks to her Longinus.
* SexIsViolence: Enjoys fighting her enemies a little ''too'' much...
* TeleportSpam: One of her abilities powerful enough to which even a post-Volume 16 Gasper can't keep up with.


[[folder: Qlippoth Faction]]

The reorganized remnants of the Khaos Brigade after their devastating blow in Volume 12. Under their new leaders, they revive the Evil Dragons in an attempt to bypass the Dimensional Gap, and invade other worlds.

!! Euclid [[spoiler:Lucifuge]]

He first appears in volume 14, giving back Issei the three first-years who were kidnapped during the events just so he can study their fighting prowess. [[spoiler: Oh and he's Grayfia's younger brother.]]
* ArmorPiercingQuestion: He asks both Issei and Sirzechs one question: [[spoiler: "What is a devil?" While Issei didn't have an answer to his question, he did note that Euclid's just insane.]]
* AwesomenessByAnalysis: [[spoiler: By using the power of the Holy Grail he was able to create a replica of Issei's Boosted Gear from the information he collected of Ddraig's soul and the Sacred Gear from Issei's [[ChekhovsGun original body]] left in the Dimensional Gap.]]
* {{Badass}}: [[spoiler: ''[[CurbStompBattle Curb stomped]]'' Issei while the latter has his CCQ armor equipped and Euclid has an imitation of the Scale Mail.]]
* CainAndAbel: [[spoiler:He's the younger Cain to Grayfia's older Abel.]]

* SuperpowerLottery: [[spoiler: ''[[NoSell No Selling]]'' Sacred Gear abilities. And that's not even his true powers yet.]]
