!The Occult Research Club

An extracurricular club that most of the major characters in the series are a part of. Despite the club's name, very little actual ''research'' is actually done; after all, the members are not (or in some cases, ''no longer'') human. The club is really just a front for Rias, her "family," and later, other supernatural beings, and it provides cover for their operations; namely dealing with paranormal activity and destroying hostile supernatural beings. The members often use the club as an excuse to get out of any classes they might be in at the moment when an emergency pops up, and the old schoolhouse in which they meet is secluded enough to prevent scrutiny from normal human students.


[[folder:Tropes Relating to the Club in General]]
* AllWomenAreLustful
* AlmightyJanitor: Everyone in the Club, except Rias and Azazel, are low-ranked devils. Rias is currently one of the weaker members of the Club. You do the math. [[spoiler:Even after Issei, Akeno and Kiba's promotion, it's implied they are ''still'' not promoted to a level which would indicate their strength. Justified by Sirzechs, since he believes they're far from ready to handle the responsibilities and pressures of a high-ranked devil.]]
* BadassCrew: [[IncrediblyLamePun Hell]] yeah!
* BadassFamily: What Rias regards her club as, with her as the "mother" that holds it together.
* BalancedHarem: What makes this group different from the other tropes is that Issei is a [[AllMenArePerverts unashamed pervert]] and a HaremSeeker. However, he is also a BadAss ChivalrousPervert who [[YouAreWorthHell literally goes through hell]] for the girls. The girls decide fairly early on that they are [[MarryThemAll ALL going to get with him]], and instead of fighting over him, they fight over who he pays the most attention to.
* BattleHarem: Even if you include Kiba and Gasper. It gets lampshaded by the [[WordOfGod author himself at one point.]]
* BettyAndVeronica: Within the Occult Club, we have Asia as the Betty and Rias, Xenovia, and Akeno as the Veronicas for Issei's Archie. Add:
** Irina, being Issei's ChildhoodFriend, also acts as a possible Cheryl.
* [[spoiler:BreakTheCutie: Almost all the members of Issei's harem after his "death", showing how psychologically dependent they are of him due to his help in overcoming their respective DarkAndTroubledPast. Fortunately subverted after he comes back to life with some draconic backup.]]
* DysfunctionJunction: Almost every single member of the club has or had issues that needed resolving.
* FiveManBand:
** Original setup
*** TheLeader: Rias
*** TheLancer: Akeno
*** {{The Big G|uy}}irl: Koneko
*** TheSmartGuy: Kiba
*** TheChick: Asia
* HeroicBSOD: [[spoiler:''Everyone's'' reaction after Issei's (temporary) death. Rias locked herself up in her room, embracing Issei's Evil Pieces, Akeno lay nigh-lifeless on the sofa, Asia and Ravel are openly crying their eyes out, Koneko tried to keep her composure only to also break down crying, and Kiba had to hold back his tears while having to attend to Ruval and Riser, who offer their sympathies to the team, and later Baraqiel, who came to comfort Akeno. Only Irina, Xenovia and Rossweisse were never immediately in the know, and Gasper was deliberately left in the dark because it'd be too traumatic for him (and when he did, he didn't take it well, [[NoHoldsBarredBeatdown but not in the way Georg expected]]).]]
* MomentKiller: ''Everyone'' in Issei's harem is this to the others. It can count as a meta-example as well as this is Ishibumi's way of cooperating with the CantHaveSexEver clause in writing this story.
* PyrrhicVictory: [[spoiler:They did win the Rating Game against the Student Council, but lost a lot of members to pull it off, and their ratings were lowered as a result.]]
* RagtagBunchOfMisfits: They have a devil princess, a modified human, a miko and human/fallen angel hybrid, three very ditzy believers of God, a nekomata, a crossdressing vampire, a mad scientist fallen angel, a money-loving valkyrie, a demon phoenix, and finally a very perverted high school boy turned demon.
* SingleTargetSexuality: The girls toward Issei for one reason or another. Rias sees all men as the same, Akeno hates men, Asia was too innocent to find interest in the opposite sex, Irina and Xenovia were both raised in church, Koneko dislikes perverted things. However, they seem to all enjoy Issei and all love him to the point [[spoiler: they can't live without him.]]
* SwitchingPOV: The story is usually told through Issei's perspective, though at certain points we see the story through other characters' eyes, namely, Rias, Kiba (secondary narration if there's something going on with Issei), Azazel (when there's a discussion with the leaders involved), Asia for a brief period, and [[LowerDeckEpisode Irina in one of the short stories]].
* TookALevelInBadass: Throughout the series, as time goes on ''everyone'' in the Occult Research Club starts actively grinding levels in badass.
* TrueCompanions: Despite all the girls wanted to be with Issei, they still trust and help each other no matter what happen.
* TryNotToDie: When Xenovia and Irina were able to get out of the dimension caused by Georg, they tell Issei to survive. [[spoiler: [[OurHeroIsDead Guess what happens to him.]]]]
* UndyingLoyalty: To each other. [[spoiler:Even from ''beyond the grave''.]]
* UnskilledButStrong: During the Rating Games the Club showed a lack of experience, hence they often don't do so well. This is best exemplified in their match against Souna's group, which almost spelled defeat for them.

!!Issei Hyodo
->'''Role:''' Pawn (8)\\
'''Species:''' Human / Reincarnated Devil / [[spoiler:Humanoid Dragon]]\\
'''Voiced by:''' YuukiKaji (Japanese) and Scott Freeman (English)
The primary protagonist, a pervert who gets killed by his first girlfriend, but not before wishing to be brought back to life -- a wish so powerful Rias gets to answer his call and resurrect him as a devil. He dreams of being a harem king, unknowingly already in the middle of being one.
* {{Adorkable}}: A trait that keeps his harem growing.
* AbhorrentAdmirer: In one of the short stories of Volume 8, it's revealed that [[spoiler:he has a ''female gorilla spirit'' who has a crush on him]]. Needless to say, he's not amused.
* AboveTheInfluence: When a despairing Akeno came to him naked and sad, wanting to have sex with him [[spoiler: due to her depressing memories of her past and her father]] Issei refuses despite wanting to have sex with her, as he wouldn't do it with someone who was in such a depressing state.
* ABoyAndHisX: A boy and his dragon partner who's sealed in his left arm to be exact.
* AchillesHeel: Notable in that he's got ''twice'' the number of weaknesses because he's both a dragon and a devil.
* AdultFear: [[spoiler:When he finds out that Koneko, Gasper and Ravel were kidnapped by magicians after they tried protecting an innocent human.]]
* AlmightyJanitor: In the first season of the anime anyway. He's considered fairly weak compared to the other characters, as he's only a pawn in chess terminology. That said, he can also acquire the powers of the other chess pieces, and due to his Sacred Gear, once he starts training and mastering its use, he becomes quite deadly.
* AscendedFanboy: He's a fan of SuperSentai shows alongside Irina, and he finally stars in the "Oppai Dragon" show. He's conflicted, however, between elation and embarrassment over the title, though kids do love it.
* [[spoiler:AscendedToAHigherPlaneOfExistence: He's got both Great Red ''and'' Ophis' existence within him.]]
* [[spoiler:AwesomenessByAnalysis: Took a look at Sirzechs' way of bending his Power of Destruction to hit a specific target, and practiced till he was able to pull it off.]]
* BackFromTheDead: [[spoiler:''[[AscendedToAHigherPlaneOfExistence Twice!]]'']]
* {{Badass}}: Just to count the ways...
** BadassAndChildDuo: When he and Kunou were the only ones who got together when everyone got separated at Kyoto.
** BadassBoast:
--->[[RefugeInAudacity "President Rias Gremory's virginity belongs to me!!"]] ''(During [[spoiler:Riser and Rias' engagement party]])''
--->"If you want to burn me, bring me a phoenix or a dragon!" ''(While fighting a fire mage)''
** BadassCreed: [[spoiler:Gains this after getting Crimson Queen mode instead of Juggernaut Drive, and is ''fighting off [[DeadlyUpgrade the original version's]] creed while chanting it''.]]
--->[[spoiler:"I, who is about to awaken, am the Red Dragon Emperor who has discarded the principles of ambition. I walk the road of righteousness by having infinite hopes and dreams. I shall become the King of Crimson Dragon. And I promise you all! I shall show you the future that shines in true crimson light!"]]
** BadassFingerSnap: When unleashing Dress Break.
** BadassPacifist: Would prefer talking rather than beating up his enemies. [[spoiler:And that includes the past users of Boosted Gear.]]
** BadassUnintentional: He just wants a harem and not to fight at all. Doesn't stop him from being one.
** BroughtDownToBadass: [[spoiler:Thanks to Ddraig sleeping, he can't access his Balance Breaker state and is back to where he was before. Does this stop him from kicking ass? ''Hell no.'']]
** CrouchingMoronHiddenBadass: He's usually thinking about perverted things, but when push comes to shove...
** DareToBeBadass: Delivers this to Gasper when he held the DistressBall in Volume 4.
--->"However, Gasper! It�s no use if you don�t get up on your own, you know? After receiving encouragement by a girl, next is standing up! [[ItMakesSenseInContext Don't you have a wonderful pair of balls on you!?]]"
** DidYouJustPunchOutCthulhu: [[spoiler:Gets to land the final blow against Loki.]] Another occasion is PlayedForLaughs in Volume 14 where, after doing the StraightMan act for half the time, he finally [[spoiler:smacks Fafnir after the latter [[ItMakesSenseInContext keeps on sniffing Asia's treasured panties.]] The trope fits because Fafnir's a ''dragon king'' on par with Tannin!]]
** HeartbrokenBadass: His thoughts reveal that he's still haunted by Yuma/Reynalle's betrayal and [[spoiler:his decision to allow Rias to kill her]].
** IntimidationDemonstration: [[spoiler:Does this to Diodora when he punches the ground so hard it causes a crater. This pretty scares him out of fighting Issei.]]
** OneManArmy: [[spoiler:Defeats an entire group of middle-class grim reapers, beings ''stronger than high-class devils'', by himself. And this is with him only using Balance Breaker and at this point, he's a lot weaker because he just fired off two Dragon Blasters, and used Gift on Rias and Akeno. This surprises Siegfried as to how strong Issei really is.]]
** SubmissiveBadass: He's even more powerful than ''any'' member of his group, but he's still going to follow Rias' orders no questions asked.
** TookALevelInBadass: ''Actively grinds millions!'' [[spoiler:Showcased with four of his evil pieces ''becoming Mutated Pieces'']]
** UnderestimatingBadassery: Seems like a lot of people think that he's not as badass as he's supposed to be. He proves them wrong all the time.
* [[spoiler:BattleInTheCenterOfTheMind: Past users of Boosted Gear wanted him to use [[DeadlyUpgrade Juggernaut Drive]] again. He only gets saved thanks to the power of the children and Irina cheering for him, Sairaorg's encouragement, and one of the past users of Albion, [[ChekhovsGun whose consciousness resided in a fragment he absorbed from Vali]].]]
* BeatThemAtTheirOwnGame: [[spoiler:Used Samael's poison from his body when he fought Shalba, infused it with a bullet of Gogmagog he found at the Dimension Gap alongside Ophis and Great Red, and used it against Cao Cao.]]
* BerserkButton
** Dare hurt anyone from his harem, physically or emotionally, and he's not going to pull back on the punches. [[spoiler:Riser and Shalba learned the hard way.]]
** Invoked by Vali to make him fight harder. ''It works too well.'' [[spoiler:Said button is ''halving his harem's breasts''.]]
** [[spoiler:Tell him that you're going to harm children in his presence. [[CurbStompBattle We dare you]].]]
* BigBrotherMentor: Mainly to Gasper as he teaches the kid on how to [[TookALevelInBadass take a level in badass]]. Also to Milicas as well.
* [[spoiler:BigDamnHeroes: Shows up BackFromTheDead with Great Red and Ophis accompanying him.]]
** [[spoiler:DynamicEntry]]
* BoomHeadshot: Achieves this [[spoiler:in his second fight against Cao Cao, who lost his eye after that.]]
* BreakTheCutie: His entire Yuma/Reynalle experience -- it took several volumes for him to recover fully.
* BreathWeapon: He learns how to breathe fire [[spoiler:[[TrainingFromHell after training with Taninmin]]]]
* ButForMeItWasTuesday: Doesn't even remember the shadow-user EliteMook that he fought at the warehouse when they meet again at Kyoto.
* CallBack: [[spoiler:How he defeats Cao Cao is the same way as to how he defeats Riser: not by pure power, but by being CrazyPrepared and some IndyPloy mixed in.]]
* CantActPervertedTowardALoveInterest: Averted. He'll still make lecherous passes even though [[spoiler:he finally is able to confess to Rias. Case in point: use Gift on the latter's breasts.]]
* TheChampion: For Rias, he'll do ''anything''.
* CharacterDevelopment: Compare Issei from Volume 1 to the current Issei; he's grown a lot in a few months. [[spoiler: Best shown when he wholeheartedly entrusts Rias to Kiba's care during their trip to Romania. If this was the old Issei, he'd [[GreenEyedMonster be jealous of Kiba]].]]
** Another sign is that at the beginning, Issei thought the purpose of a Peerage is to have his own harem. But he learn later on is that the Peerage is meant for support and battle, and start taking his future and Peerage seriously as he want a team that doesn't shame Rias or her family. Some people even points out that Issei perverted thinking has toned down a bit as he matured and knows what is important during battles.
* ChestBlaster: [[spoiler:What Longinus Smasher's true form looks like.]]
* ChickMagnet: He's got (in order of who liked him first) Asia, Rias, Akeno, Koneko, Xenovia, Irina, Ravel, [[spoiler:Rossweisse and Ophis]]. That's not counting the many admirers he has, much less ''[[EvenTheGuysWantHim the guys who want him.]]'' According to Ddraig, dragons are {{Chick Magnet}}s.
* ChivalrousPervert: As much as he wants to make any moves, he just can't touch Rias because she's too good for someone as lowly as him, and Asia because she's too pure to corrupt easily. Oh, and [[OhCrap God help you if you hurt his harem in any way.]]
* ClothingDamage: We here at TV Tropes have currently [[Pantheon/{{Power}} deified him for this trope.]]
* CluelessChickMagnet: Initially he is even more clueless than [[Manga/{{Kampfer}} Natsuru Senou]]. Justified, due to [[BreakTheCutie the psychological damage]] Yuma has caused him which took several volumes for him to fully recover from.
* CombatPragmatist: He'll find a way to beat you no matter what it takes. [[ClothingDamage Dress Break]] plus a Dragon Blast for girls busy covering themselves, and being CrazyPrepared with IndyPloy tactics for boys. If you're weaker than him however, [[CurbStompBattle well...]]
* CombinationAttack: Due to his [[StatusBuff Gift]] powers, he's able to amplify his ally's attacks and launch a more powerful version. To wit, he pulled off a FieldOfBlades with Kiba, amplified Power of Destruction with Rias, amplified Akeno's Holy Lightning and his personal favorite with Gasper: Dress Break during a time freeze.
* CoolSword: Gains the Holy Sword Ascalon after Michael gives it to him [[ItWasAGift as a gift]].
* [[spoiler:CoolShip: The ''Skithblathnir'' (later named ''Ryuuteimaru''). It's currently in its toy form, but according to [=MacGregor=], it can transform into a giant airship. [[PowerPerversionPotential Or a flying harem palace.]] This will also depend on Issei's aura.]]
* CrazyEnoughToWork: Most of his powers are pretty much this.
* CrazyPrepared: His entire fight with Riser at the engagement party and his fourth battle against [[spoiler:Cao Cao]]. Hell, ''any'' of his fights that involve this trope tend to be a lot more interesting and awesome than others.
* CurbStompBattle: In the beginning, he's the receiver of this. Then he started training and now, ''he's delivering'' all the curb stomps to weaker devils. Just ask [[spoiler:Diodora or Shalba]].
* DangerousForbiddenTechnique: Longinus Smasher. [[spoiler:It's powerful enough to put ''Power of Destruction'' to shame. As in capable of ''destroying'' the entire Underworld at full power. It also requires Issei to be under Juggernaut Drive, which can prove fatal unless fully mastered. Merging with Great Red allows him to use it without side effects, though WordOfGod claims this is just a one-off ability. Ddraig later notes that it is an ability he is ''not'' supposed to have, hinting it was sealed away by God.]]
* DarkAndTroubledPast: He treats his FreudianExcuse like it was one of these. [[HilarityEnsues It's actually hilarious.]]
* ADateWithRosiePalms: After Rias appears to him all of a sudden in Volume 2 and then goes back to her home. Thankfully, the anime omitted that little detail.
* DeadlyUpgrade: [[spoiler:Juggernaut Drive. Makes him a lot stronger at the cost of his sanity and reducing his devil lifespan by 99%.]]
* DeadpanSnarker: He has his moments, normally when talking to [[ThoseTwoGuys Matsuda and Motohama]]. One particular example occurs when he tells them he's going to ditch them to go to Rias' home (in the Underworld).
--> '''Matsuda and Motohama:''' "Go to hell, you bastard!"\\
''(Issei hangs up the phone)''\\
'''Issei:''' "Well, I ''am'' going to Hell."
** He also does it (internally) when Rias can't tell who the Satan Rangers are.
* DeathGlare: He usually receives this to the girls. [[spoiler:But if it's from ''him'', [[TranquilFury you might want to run away pretty quick]]. Even Sairaorg felt a cold chill in his spine when he sees him do this, even in a Ratings Game.]]
* DeclarationOfProtection: Threaten any of his friends, especially Rias or Asia, and he'll pretty much pull this trope out. Expect a CurbStompBattle if he really does have to fight, even if he gets beat up a little bit first.
* DespairEventHorizon: Crossed it when [[spoiler:Asia "[[ILetGwenStacyDie died]]" the second time. [[DeadlyUpgrade Then he unlocks Juggernaut Drive]] and ''[[ImAHumanitarian eats Shalba]]''.]]
* {{Determinator}}: Best exemplified with his fight against Raynare and went on from there.
* [[spoiler:DidYouJustRomanceCthulhu: He gains Ophis' affection from the way she clings at him.]]
* [[spoiler:TheDreaded: A ''heroic'' example. After his "little stunt" of coming BackFromTheDead, the Anti-Maou faction has started to fear him because he survived Samael's blood curse, something that should have killed him already. Not to mention, he came back with Great Red's flesh and Ophis' powers.]]
* DropTheHammer: [[spoiler:Briefly wields Thor's hammer, Mjolnir, against Loki.]]
* [[EveryoneHasStandards Even Perverts Have Standards]]: Issei might be an open pervert with active wishes for a harem, but that's because he treasures women. In the anime, when Riser kisses/molests his queen just to make him jealous, then makes a comment to Rias implying she'd just make a good notch on his belt, Issei is ''furious''. Issei even refuse having sex with Akeno while she was in a despair state, believing it will just hurt her even more than ever.
* EvenTheGuysWantHim: It's strongly implied that Kiba and Gasper want to be more than friends with him, and even a harem guy like him is actually disturbed by the implications.
* EvilIsHammy: Invokes this (at least in a girl's eyes) whenever he uses Dress Break and Bilingual, especially under Gasper's time freeze. Even Koneko [[LampshadeHanging lampshades]] it that only villains ever get to be that hammy.
* {{Expy}}: WordOfGod states that he designed Issei after [[Anime/SCryEd Kazuma]], especially where Boosted Gear is located at.
* [[spoiler: FamousLastWords: His final words before he succumbs to the Samael curse: "I love you Rias....." [[BackFromTheDead Of course it didn't stick.]]]]
* {{Fanboy}}: Of Sairaorg, after witnessing him settle a mess.
* FatalFlaw: Issei knows his perversion can and will get the better of him, but he just can't help it. Another Fatal Flaw that was pointed out by Azazel, is that Issei cares too much for his teammate that will make him rush toward a battle without thinking if they got hurt, which could be a problem if he has his own Peerage.
* FingerSuckHealing: In the manga, after [[spoiler:giving his left arm to Ddraig (turning it into a dragon arm) in order to gain power to beat Riser]], he periodically receives this from Rias and Akeno to return it to normal.
* TheFirstCutIsTheDeepest: Despite his desire for romance, Yuma's betrayal fostered in him a fear of rejection.
* FirstEpisodeResurrection
* FirstKiss: To Rias in volume 2. [[spoiler: Subverted in volume 18 when Irina reveals that she kissed him long before the series starts and he forgot all about it.]]
* FirstNameBasis: He calls everyone in the group, aside from Kiba and Rias, by their first names, although the latter actually wanted to be called "Rias" instead of "Club President". [[spoiler:He finally does call her by her first name at the end of Volume 10.]]
* {{Foil}}: To Vali, for having the greatest Red Dragon-White Dragon library and the fact that their origins and attitudes to their powers are different -- Issei was a completely unremarkable boy who's more than willing to talk it out with past hosts of Boosted Gear, while Vali is a descendant of the original Lucifer who's more interested in dominating past users of Divine Dividing. He also has some contradistinctions with Cao Cao -- both have companions willing to die for them -- except Issei would want to keep them alive, while Cao Cao will do anything, including [[BrainwashedAndCrazy brainwashing people]], for his cause.
* FreudianExcuse: PlayedForLaughs in a Volume 8 short story where he recalls to the Club an incident as a seven-year-old, when he and other boys listened to an old man teaching them to suck girls' breasts. When he went to see him again, he found him [[RealityEnsues being arrested by cops and later sentenced to ten years behind bars]], much to [[ChildrenAreInnocent his confusion]]. Issei recounts that as though it was a DarkAndTroubledPast on par with their own traumatic backstories. Koneko is not amused.
--> '''Koneko:''' "...A man who talks about indecent things to a child... A real pervert. The worst story ever."
* FriendToAllChildren: Apparently, children are attracted to him for some reason.
* [[spoiler:GodWasMyCoPilot: Combines with Great Red to ''{{Kaiju}}'' size.]]
* [[spoiler:GoOutWithASmile: When he died in the finale of Volume 11, this was the image shown to us.]]
* GroinAttack: He gets hit after blocking a speeding ball aimed for Kiba.
* HalfHumanHybrid: A Human-Devil-Dragon hybrid.
* HaremSeeker: His ultimate goal after being convinced by Rias.
** What is interesting to note is that in volume 1, his thought process on having a harem was similar to a [[VisualNovel/SchoolDays certain douchebag]] but eventually evolves into a benevolent one, if still massively perverted.
* TheHeart: The Occult Club sticks together mostly because of him.
* HeroesWantRedheads: Out of his harem, he loves Rias the most but he CannotSpitItOut for fear of destroying their relationship, partly due to emotional damage from Yuma's betrayal.
* HeroicRROD: Due to his physical limits, he cannot call out Ddraig's full power for more than ten seconds without sacrificing a body part [[spoiler:(at least initially)]]. [[spoiler:And when he used [[DangerousForbiddenTechnique Juggernaut Drive]], his lifespan was cut down to 100 years, so he'd be the first to die of natural causes amongst Rias' team, though this has been nullified following his death and rebirth during Volumes 11-12.]]
* [[spoiler:HeroicSacrifice: Past users of Boosted Gear sacrificed their souls just to keep his soul safe in Volume 12.]]
* [[spoiler:HesBack: [[BigDamnHeroes And guess who's with him.]]]]
* HiddenDepths: He's good at sewing, [[DamnedByFaintPraise something that surprises Koneko]].
** He's also an excellent sculptor. He managed to make a perfect nude Rias figurine with his eyes closed. This duly impressed his entire class to the point that there was a bidding war over the figure. When he ultimately handed the figure to Rias instead, both she and Akeno were duly impressed. Issei would have happily made one for Akeno also except that both Rias and Asia loudly objected. (Since Akeno basically spelled out her idea of "modeling" right in front of them.)
* [[spoiler:HornedHumanoid: After activating Juggernaut Drive the first time.]]
* IdiotHero: Initially, with regards to romance; otherwise he has a lot of common sense and is actually a quick learner.
* InformedFlaw: Everyone treats him as the weakest holder of Boosted Gear. Initially justified, though he eventually blows these assumptions apart with his rapid progress. Nowadays only the really strong characters, such as [[AuthorityEqualsAsskicking Azazel]], [[BornWinner Vali]] and [[BadassNormal Cao Cao]] still call him a "newbie", and even then they treat that as a compliment, knowing Issei can and ''will'' transcend his flaws.
* IntergenerationalFriendship: With lots of characters in the series, most of which place his as the younger one, with latest additions being [[spoiler:Ophis and Great Red]].
* IronicEcho: He promised Koneko that he will never use Dress Break on his allies. [[spoiler:The he accidentally uses it on Asia and Koneko in Volume 3, because he was targeting Irina at that time, again to Asia in Volume 6, and against Rossweisse in Volume 9 to surpass her in a friendly duel. The one with Xenovia in Volume 8 doesn't count because it was his clone running loose.]]
* JackOfAllStats: Pawns have the secondary ability of "Promotion" if they are deep in enemy territory, [[ChessMotifs just like in real chess]]. Which allows him to promote himself to any piece except a King, gaining that piece's abilities.
* [[spoiler:TheJuggernaut: Juggernaut Drive. Duh.]]
* [[spoiler:{{Kaiju}}: When he is resurrected and brings Ophis and Great Red, he combines with the latter and becomes ''gigantic sized'' to take out Annihilation Maker monsters. WordOfGod states that it's a one-time form only.]]
* ALadyOnEachArm: After [[spoiler: coming back from the dead]] the girls became more affection toward Issei to the point Rias and Akeno grab both his arms while walking to school. Even Asia was thinking of riding on his back.
* LargeHam: Every single time he uses Dress Break and Bilingual to his female opponents, he will be bringing ham. Just ''how'' hammy was when this skill was first used in the anime? He breaks out his devil wings, pulls off a pose fit for a Franchise/KamenRider show, and lets loose with a finger snap. ''While OminousLatinChanting is playing on the background.''
* LetsFightLikeGentlemen: He insisted to Koneko that he fight Saji in a one-on-one match when Koneko tells him that it's a team battle. He then outright tells Koneko that if Saji wanted to, he could've used his Sacred Gear on her.
* LivingEmotionalCrutch: An ''incredibly'' large one to Rias, Akeno, and, to a lesser extent, the rest of their team. [[spoiler:When he (temporarily) died, Volume 12 starts by showing its devastating consequences on the team.]]
* LovableSexManiac: Everyone in his harem loves him and [[IfItsYouItsOkay they're alright with his perverted antics]]. This was also pointed out when Issei lost his perverted nature thanks to Azael, and the girls wanted him back to the way he was.
* LoveHurts: It takes him nine volumes to even recover from Yuma's betrayal, and what does he get [[spoiler:after confessing to Rias? One volume later, he dies trying to save Ophis]].
* MagikarpPower: How his left gauntlet works. Every ten seconds, his power doubles. Get it boosted long enough and he can even ''[[DidYouJustPunchOutCthulhu kill any deity]]''. Of course, due to the long preparation, no [[GenreSavvy one's gonna]] [[WhyDontYouJustShootHim wait for him to power up]] completely and get their asses kicked.
* MagneticHero: He attracts special people like crazy. Practically everybody important in this series had some form of interaction with him. This is actually lampshaded by Sirzechs when he's talking with Azazel.
* MaleFrontalNudity: In Season 1 Episode 2 and it's uncensored, as a FreezeFrameBonus.
* AManIsNotAVirgin: Averted, much to his chagrin because he really wants to lose it but can't because of his indecisiveness borne from trauma over Yuma's betrayal.
* MesACrowd: Something Azazel experimented on him. Three hundred of him to be exact. And yes, the cover illustration for said short story is a ShoutOut to ''Film/ThreeHundred''.
* MeaningfulEcho: [[spoiler: His BadassCreed, especially about holding both infinity (Ophis) and dream (Great Red), is a lot more significant now that he's got ''both'' existences within him.]]
* MistakenForGay: After Kiryuu spreads a photo of Issei and Kiba singing a duet together, rumors of them having a relationship spread like wildfire. Doesn't help that Kiba [[AmbiguouslyGay sometimes even outright tells Issei that he'll protect him]]. Issei just thinks he's nuts.
* MistressAndServantBoy: He's the servant and Rias is the mistress.
* MrFanservice: After his TrainingFromHell with Tannin, he has developed so fit a body half of his female classmates fell for him, his notoriety for his perversions notwithstanding.
* MultiArmedAndDangerous: He grows extra limbs, some of which are sword-like, [[spoiler:when in Juggernaut Drive.]]
* MultiformBalance: How [[SuperMode Illegal Move Trident]] works.
** FragileSpeedster: Welsh Sonic Boost Knight gives up armor in exchange for speed.
** GlassCannon: Welsh Blaster Bishop has a long charge time but has very destructive attacks.
** JackOfAllStats: Normal Balance Breaker has no weakness but doesn't add any special powers.
** LightningBruiser: Cardinal Crimson Promotion basically combines all 3 modes' strong points without any of their weakness. However, it takes the mastering of all three forms just to maintain it.
** MightyGlacier: Welsh Dragonic Rook has heavy attack and defense but due to the extra armor in this mode speed is lowered.
* MundaneUtility: How he acquired Dress Break in the first place was to peel vegetables at a distance.
* NakedOnRevival
* NiceGuy: Despite being a pervert, he's actually one of the kindest, most generous people in the series. Part of the reason why girls are falling head over heels for him.
* NiceJobBreakingItHero: [[spoiler:Destroying one of Cao Cao's eyes didn't exactly end well when he gets a rematch with replacing his now-missing eye with Medusa's eye.]]
* NinjaPirateZombieRobot: A perverted high school student that is both a dragon and a devil.
* NoOneGetsLeftBehind: [[spoiler:Stays behind the group in Volume 11 to rescue Ophis from Shalba.]]
* NormallyIWouldBeDeadNow: This trope happens to him so many times that it's not even funny anymore. To wit:
** Didn't accept a membership flier from Rias' Familiar at the start of the story? He would have been KilledOffForReal by Yuma.
** Rias didn't rescue him from Dohnaseek, and later Freed? Would have died.
** Didn't attain Balance Breaker against Kuroka? Would have died.
** [[spoiler:Never used Phoenix tears before his second fight with Cao Cao? Would have died.]]
** [[spoiler:The Dragon Eater curse would have killed him had Ddraig and Boosted Gear's past hosts had not interfered.]]
* {{Nosebleed}}: Too many times to count. However, in the later volume, Issei gotten somewhat use to the girls antic and became more calm about it.
* ObliviousToLove: As much as he's perverted, he doesn't catch the fact that all of the girls in the club love him. Justified, due to his recurring trauma from Yuma/Reynalle's betrayal.
* ObviousRulePatch: Every single time he makes up a new move, [[TournamentArc the Rating Games]] ''always'' outright ban that move after use the match. Doesn't mean he can't use it outside a Rating Game, though.
* [[spoiler:OfficialCouple: After ten volumes, he's officially a couple with Rias. Then again, it's not like it ever stopped his harem, nor the fact that he hasn't even fulfilled his dream.]]
* OOCIsSeriousBusiness: Normally, he would proclaim his love for breasts, make some smartass comments, and as hot-blooded as possible. However, when [[LetsGetDangerous he really gets serious]], other characters note that he's different from the way he usually is.
* TheOnlyOneAllowedToDefeatYou: Inverted. [[spoiler:Cao Cao, Vali, Sairaorg and Kiba all express their wishes to defeat Issei one day. Them being all guys, Issei wasn't amused by it.]]
* [[spoiler:OurHeroIsDead: Throughout Volumes 11-12.]]
* [[spoiler:PalsWithJesus: He is the only person Ophis considers a friend.]]
* PapaWolf: To all the younger girls, but ''especially'' Asia and Koneko. Just ask Kuroka and Diodora.
* PersonOfMassDestruction: His missed attacks can blow up ''mountains''.
** [[spoiler:[[ShoulderCannon Trident Bishop]] can destabilize ''artificial dimensions''.]]
** Kiba even points out later on that whenever they train, it just feels so tiring to train with Issei because one hit from Issei ''will kill him''.
** The first time he uses [[WaveMotionGun Trident Bishop]], he would have killed the entire [[BadassNormal Hero Faction]] had Cao Cao not saved them.
* PornStash: Thinks he hid it pretty well until his mom blurts out where it's located at. [[spoiler:Later on, the girls get to look at said stash, which humiliates Issei even further.]]
* PowerAtAPrice: [[spoiler:In the beginning (at least with his battle against Riser), he borrowed Ddraig's power at the cost of his left arm, turning dragon-like -- not that he minds it, as Rias and Akeno have to do "[[ThisAndThat that sort of thing]]"[[note]]It looks like they're giving him a blowjob[[/note]] every couple of days to turn it back to normal.]]
* PoweredArmor: [[OverlyLongName Balance Breaker: Boosted Gear Scale Mail]]
* PowerPerversionPotential: ''Half'' of his abilities works like this.
** ClothingDamage[=/=]TheNudifier: Dress Break -- anyone he touches, his/her clothes get shredded off. This was declared an illegal move in subsequent [[TournamentArc Rating Games]] where, technically, there are no rules.
** HearingVoices: Bilingual -- Yes, he can hear a woman's secrets and plans just from their breasts.
* ThePowerOfLove: Issei is powered by this... but mostly he's powered by lust.
** Note that this is not a good thing. The first time it happens is when he thinks Asia has been killed by Shalba. He loses his shit and literally eats the guy alive. Issei on The Power of Love is absolutely terrifying.
* PunchedAcrossTheRoom: [[spoiler:How he defeats Yuma/Raynare.]]
** DefenestrateAndBerate: In the anime, [[spoiler:Yuuma]] goes out a window instead, only to be hauled back in by Koneko.
* RagsToRiches: While he wasn't exactly destitute at the beginning, he was middle-class at best. After his [[ShowWithinAShow TV show]] got started, his income skyrocketed. It's currently managed by Grayfia because he isn't ready to deal with that much money yet.
* TheReasonYouSuckSpeech: Delivers this towards [[spoiler:Shalba the second time he [[CurbStompBattle curb-stomped him.]]]]
* RedBaron: The "Red Dragon Emperor" (by taming Ddraig), "Breast Dragon Emperor" (by attaining Balance Breaker through by pressing Rias' nipples), and "Hero of the Underworld".
* RedIsHeroic: His Red Dragon Emperor Armor.
** RedOniBlueOni: The red to Kiba's blue, with the armor mention above.
* RequiredSecondaryPowers: He needs ''a lot'' of stamina just to be able to make Boosted Gear work properly.
* TheRival: While Vali is more likely his rival thanks to their Sacred Gears, he considers his true rival to be Saji.
* RivalsTeamUp: With Vali against Loki.
* RoarBeforeBeating: [[spoiler:When in Juggernaut Drive against Shalba.]]
* ScreamsLikeALittleGirl: ''He's the one who screams'' when he accidentally walks in on Asia while she was in the shower instead of the other way around.
* SealedInsideAPersonShapedCan: Issei is the can to Ddraig.
* SecondYearProtagonist
* SeriousBusiness: If you want to put on a strip show for him, [[spoiler:''take out your bra first before your panties''. Sairaorg's Bishop found that out the hard way]].
* ShipperOnDeck: Ships Saji to Souna, which becomes a bit complicated when [[spoiler:he starts calling Souna on a FirstNameBasis]], as well as Shinra/Kiba, which he further enforces [[spoiler:once he realizes that the latter is apprently becoming too close to him for comfort]].
* ShoulderCannon: His Illegal Trident Bishop form.
* [[spoiler:SickeninglySweethearts: With Rias. Even referred by Azazel as "that stupid couple".]]
* SignatureMove: If he's fighting a female opponent, 90% of the time he'll be using either Dress Break/Bilingual/both and a Dragon Shot.
* SpannerInTheWorks: Wrecks his opponents' plans like no tomorrow.
** Reynalle: [[spoiler:Punched her in the face so hard she got blown out.]]
** Riser: [[spoiler:Beats him up at ''his own'' engagement party.]]
** Souna: [[spoiler:Uses Bilingual on her entire team and had their plans found out.]]
** Diodora: [[spoiler:Defeated Reynalle, thus getting Asia's affection.]]
* SpellMyNameWithAnS: The fan translation of the light novels and recent scanlations use "Ise" for his katakana nickname (イッセー, ''Issē'') to differentiate from his kanji name (一誠, ''Issei''). This is averted in FUNimation's subtitled streams, where they use Issei for both readings.
* SpitTake: When his mother asks him when is she going to have a grandchild ever since [[spoiler:he finally calls Rias by name]].
* StatusBuff: How ''Gift'' works.
* StraightMan: When not in pervert mode, he actually becomes this -- to Asia and Xenovia when they end up praying and gain damage, to Rias when he recognized who the Satan Rangers were (while Rias thought it was a new enemy), to Bikou and Vali when they thought [[CreepyCrossdresser Mil-tan]] was a ''CatGirl'', tried this to Irina when she said she wanted to create a new club but is still joining the Occult Research Club, and to Rossweisse [[spoiler:when he lampshades how her immediate reaction to the ClothingDamage she received from Dress Break was to complain about ''[[SkewedPriorities losing her clothes that cost her money]]'' instead of immediately covering herself up.]]
* SuperpowerLottery: Subverted. While one would think that having one of the strongest Sacred Gear that doubles your power every ten seconds would be a big win? Issei himself is utterly talentless and has to compensate by going through TrainingFromHell to even learn how to use it. [[spoiler:Played straight when technically becomes the offspring of both Ophis and Great Red.]]
* TechnicalPacifist: Never kills anybody even though he beats the crap out of them.
* TenderTears: Yes, perverts are able to regard girls as people with feelings, hopes and dreams, not just objects.
* ThereIsNoKillLikeOverkill: [[spoiler:Longinus Smasher with a Great Red powerup against a beast that has a HealingFactor faster than anyone can damage. He ''obliterated'' Jabberwocky this way with assistance from Sirzechs' servants.]]
* ThisLoserIsYou: Pre Devil Upgrades and even then, Issei is a perverted and unlucky virgin who can't win sometimes.
* ThouShaltNotKill: Made it his creed to never kill anyone, and at worst give people a bloody beatdown. Even fatal attacks in Ratings Games are rendered nonlethal due to its special rules. [[spoiler:Eventually subverted, with Shalba (after their second fight).]]
* TimeToUnlockMoreTruePotential: Well, it is a shounen series after all. Except his is a bit more unconventional than the norm.
* [[spoiler:TitleDrop: Since Great Red used his powers to create Issei a body with the help of Ophis, he's now also known as the "Dragon of Dragons" or "DD" who's still in high school; or in short, ''LightNovel/HighSchoolDXD''.]]
* [[spoiler:TranquilFury: He's usually loud and hotblooded, but if he's in this state, [[YouCanPanicNow you might want to run away pretty quick]].]]
* TransformationSequence: When he puts on his Balance Breaker for the first time in the anime.
** TransformationIsAFreeAction: Yet somehow, no one attacks him while he's transforming in this form. Even Sirzechs lampshades that it's a rule to never attack while the opponent is transforming.
* UnskilledButStrong: His main problem once he actually starts getting stronger is that he lacks technique.
* [[spoiler:WeCanRebuildHim: His old body is destroyed beyond repair, so Great Red and Ophis creates him a new, fully draconic body.]]
* WeDoTheImpossible: [[spoiler:Summoning a god from another dimension that ''other gods don't even know about'' definitely counts.]]
* WeirdnessMagnet: He even [[LampshadeHanging lampshades]] that he's been attracting a lot of weird people lately.
* WhatTheHellHero: He's called out by the other members of his group when [[spoiler:asked as to what Rias really means to him. He says "Club Leader" is "Club Leader" and not as "Rias", causing Rias to run out the room crying. The other girls turn around and fix ''[[HiddenDepths his]] [[TheFirstCutIsTheDeepest emotional]] [[LoveHurts baggage]]''.]]
* [[WhenAllYouHaveIsAHammer When All You Have Are Rias' Breasts]]: Anytime Issei needs a serious power up, it's always going to be with Rias' breasts. Examples include:
** Need to attain Balance Breaker when Issei's getting curb-stomped? Push Rias' nipples.
** Need to [[spoiler:get out of Juggernaut Drive]]? Push Rias' nipples.
** Having a power-up in the middle fighting the Hero Faction? Push Rias' nipples that are ''glowing''.
** Already unconscious from [[spoiler:a Regulus Nemea-equipped Sairaorg]]? Have Rias' breasts be glowing in a crimson color.
** Need to have more firepower when your so tired after using two Dragon Blasters and Gift? [[spoiler:Use Gift on Rias' breasts and have them ''act as a battery''.]]
* TheWorfBarrage
** Possibly the ''weirdest'' one ever. [[spoiler:Dress Break doesn't work on Sairaorg's Bishop because ''she's willing to strip'', thus using said skill would be pointless because ruining a strip show is pretty bad. He then tries to use Bilingual but the only thing that's coming out from her breasts is ''which piece of clothing she's willing to take off next''.]]
** A more serious example would be his Balance Breaker Scale Mail. If you could break his armor, then it indicates that you're a threat to him. If you can't, expect to be utterly destroyed in combat with ease.
** Currently, his Trianna Rook seems to be on its way here. [[spoiler:So far, Sairaorg and Grendel have [[NoSell deflected it]].]]
* WouldHitAGirl: Piss him off by hurting his loved ones, and gender wouldn't be an obstacle as to who he'll punch.

!!Rias Gremory
->'''Role:''' King\\
'''Species:''' Pure Devil\\
'''Voiced by:''' Creator/YokoHikasa (Japanese) and Creator/JamieMarchi (English)

Declared as the beauty of Kuoh Academy the head of the House of Gremory, Rias is a top-ranked devil and Issei's master. She first appears to him after he summons her with his dying words. Taking pity on him, and also because she's interested in his Sacred Gear, she revives him with eight Pawn pieces. Referred to by everyone as "President".
* ActionGirl: Kings are supposed to [[MissionControl hang back and command their pieces]]. Rias prefers to mix it in -- and it's not a good thing, because [[WeCannotGoOnWithoutYou a team loses if their King goes down]]. Both she and Sairaorg are scolded for this.
** [[spoiler:ActionGirlfriend: After Issei confesses to her.]]
* {{Adorkable}}: When Rias caught Issei with other girls and tend to act childish about it like getting into a pillow fight with Akeno.
* BadassInDistress: That is, if you can call the engagement party with Riser being a distress moment.
* BadassPrincess
* BadBadActing: Didn't really want to play as the DamselInDistress to lure out the remaining Issei clones.
** DullSurprise: At first. [[SubvertedTrope Then she gets into it, believing Azazel's suggestion.]] Sure enough, the Issei clones go and try to rescue her.
* BattleCouple: With Issei. [[spoiler:Becomes more so when her breasts act as a battery for Issei.]]
* BedmateReveal: Doesn't mind sleeping naked with Issei.
* BenevolentBoss: She loves her subordinates so much she treats them as family rather than employees.
* BerserkButton: Hurting any one of her servants (or even witnessing other Kings mistreat their own servants) is like inviting a roasting from her. When the three fallen angels she and Akeno are confronted by in Season 1 Episodes 4-5 [[spoiler:say how funny they found Issei being taken in by Yuuma and almost killed by her to be]], she only waits long enough for Akeno to tell them they picked a fight with the wrong person before she vaporizes all three of them with one fell swoop.
* BettyAndVeronica: The Veronica to Asia's Betty for Issei's Archie when she moved to the Hyodo residence.
* BlackBraAndPanties
* BreastExpansion: Reversed; restoring Issei with her breasts after Gift being used on them causes them to ''shrink''. Fortunately (for Issei) they grow back after she rests.
* CantCatchUp: Gets hit by this hard. Unlike the rest of the club, she doesn't gain any new ability, thus she did not get any stronger than where she was at initially, to the point that she thought of herself as TheLoad during her and Issei's fight against Sairaorg and his Pawn.
* ClingyJealousGirl: After falling in love with Issei, Rias tend to get very jealous whenever girls get close to him and even said that Issei belongs to her only.
** Advent after [[spoiler: Issei confess to her and start dating]] that Rias started to accept Issei dream of having a harem and doesn't get easily jealous as before.
* CoolBigSis: Lovingly kind or sternly mature as the situation calls for it.
* CrutchCharacter: At the start, she's the strongest member in the club. As time goes on, she devolves into middle tier.
* CryCute: In one scene in Season 1's opening, after Issei rescues her from Riser, and after [[spoiler:Issei comes back to life at the end of Volume 12]].
* DarkAndTroubledPast
* FacePalm: Does this all the time.
* FirstKiss: With Issei.
* ForeignFanservice: Although they look to have similar skin tone, after Issei's mother walks in on the pair naked in bed together, she specifically tells his father he's in bed with a foreign girl.
** Probably has to do with her radiant crimson hair. (While red hair DOES exist in Japan, it's very rare unless it's on a foreigner, and native Japanese with red hair tend to dye it black to avoid ostracism.)
* HeroesWantRedheads
* IdiotHair
* IfItsYouItsOkay: She's willing to be naked in front of her servants, ''especially'' towards Issei.
* IntimateHealing: How she heals Issei's wounds from a Fallen Angel attack.
* LetsGetDangerous: After Issei [[spoiler:died and returned]], she created a new technique, considered too dangerous to use in Rating Games, because it would kill too fast for emergency teleportation to save the victim. Rias mentions she wanted it to be like that, since it's a technique to kill anyone who tries to hurt Issei again.
* [[AFatherToHisMen A Loving Big Sister to Her Servants]]: She ''really'' loves her servants; [[BerserkButton breaking their hearts and making them cry]] is a ''one-way ticket'' to the afterlife.
* MadeOfTemptation: Successfully tempts Rossweisse to join the group as teacher and Rook despite her age. Issei notes that she could have a successful career selling insurance... or anything else, really.
* MagneticHero: She has gathered quite a lot of powerful and special people in her group even before meeting Issei. Lampshaded by Sirzechs when talking with Azazel.
* MeaningfulName: Rias' Pawn is a [[ Fairy Chess Piece]] that can also move sideways. It was proposed as a way to "shake up" the rules of chess, as Issei does for the Rating Game.
* MistressAndServantBoy: She is the mistress to Issei's servant.
* MsFanservice
** InnocentFanserviceGirl: While Issei was freaking out and his mother seemed stunned, her response when she walked in on them naked in bed was a polite "good morning" without even trying to cover herself up.
* NiceGirl: Despite her strict nature during missions and training, Rias is very kind and caring toward her Peerage than most other masters.
* OneeSama: Referred to as one of the Two Great Ladies of Kuoh Academy.
* OutGambitted: [[spoiler:By Souna.]]
* PersonOfMassDestruction
* PurelyAestheticGlasses: Sometimes wears a pair of glasses, even though she has good vision.
* RapunzelHair
* RedBaron: "Crimson-Haired Ruin Princess"
** EmbarrassingNickname: Later on, she becomes known as "Switch Princess", much to her embarrassment, and blames Bikou for it. She is later called the "Crimson Bust Princess" by Azazel in Volume 11.
* RedIsHeroic
** RedHeadedHeroine
* ReligiousAndMythologicalThemeNaming: Her surname Gremory, is taken from one of the only three female demons (of the 72 demons of the Literature/ArsGoetia) -- with the other two being a wolf and a mermaid.
* ShowerScene: Multiple times, in fact.
* ShipperOnDeck: Ships Tsubaki and Kiba.
* [[spoiler: SickeninglySweethearts: With Issei in Volume 11. To the point that they forget people are watching them.]]
* SquishyWizard: She's got awesome magical attack power, but she's terrible at taking hits.
* TeamMom: Seriously, she is more of a mother to her servants than a "master" proper.
* TryNotToDie: Her one order in volume 18 when [[spoiler: a group of volunteers protect Sona's school from evil dragons.]]
* [[spoiler: ViolentlyProtectiveGirlfriend: See LetsGetDangerous above. Mess with Issei, and Rias will ''vaporize'' you.]]

!!Asia Argento
->'''Role:''' Bishop\\
'''Species:''' Human / Reincarnated Devil\\
'''Voiced by:''' Creator/AzumiAsakura (Japanese) and Chloe Daniels (English)

A former nun who Issei found and befriended while she was looking for a church in town. She gets killed by fallen angels and is revived by Rias as her Bishop.
* ADayInTheLimelight: Along with Issei, the later half of Volume 1 is spent mostly on her introduction into the Occult Research Club. Volume 6 also delves into her character's past history with Diodora Astaroth.
* AlliterativeName: Gamebreaking points for having the same initials as her Japanese voice actress.
* AmusingInjuries: Apparently her nun training is still pretty well-ingrained. If she's relieved, she usually says something like "Thank God" followed by a whimper of pain since devils cannot pray. However, there's really no excuse for her trying to read Literature/TheBible repeatedly even though it has the same effect.
* ArmorPiercingSlap: Delivers an awesome one towards [[spoiler:Diodora when he insulted Issei]].
* [[spoiler:TheArcher: She can heal allies at a long distance. If she's near an enemy, the healing aura will just dissolve. She doesn't utilize the Reverse method because it would be risky for the Twilight Healing user (that and she's surrounded by one hell of a BadassCrew anyway).]]
* BettyAndVeronica: After Rias moved to the Hyodo residence in Volume 2, she was the Betty to Rias' (and later Akeno and Xenovia) Veronica.
* BurnTheWitch: Got branded a heretic when she was discovered to be able to heal not only angels and humans, but also devils.
* ClingyJealousGirl: It starts to show up a lot more after Rias moves in with him and her in his parent's house. As a result, if Asia sees Rias doing something perverted, she'll attempt to join in. For example, if she sees Rias naked in bed with Issei, she'll start stripping off her clothes as well.
* {{Cloudcuckoolander}}: Gets better as she becomes more exposed to the world.
* ContrivedCoincidence: [[spoiler:Asia was lucky Vali and his group were around at the Dimension Gap looking for Gogmagog, otherwise she would have been KilledOffForReal.]]
* DamselInDistress: Twice in fact. The first time was when Twilight Healing was taken away from her and the second time was when [[spoiler:Diodora had her as a hostage]]. Because of her tendency to become this, Issei and Xenovia eventually made it their vow to premptively crush everything that will pose a threat to her.
* DarkAndTroubledPast
* DrivenToSuicide: Averted, due to the knowledge that even in death, Issei would be disappointed in her for doing so, even if she did it to be with him in death. Thankfully for Asia, DeathIsCheap.
* {{Dojikko}}: In her and Koneko's spinoff manga.
* FirstKiss: With Issei
* FishOutOfWater: Doesn't even know how to make orders from a fastfood chain. Though she gets better over time.
* ForeignFanservice: She's from somewhere in Europe.
* GreenEyes
* HairOfGoldHeartOfGold: Fits the trope to a T.
* IdiotHair
* IJustWantToHaveFriends: Thankfully Issei, Rias and their friends are there for her.
* InnocentFanserviceGirl
* MeaningfulName: Her surname is [[GratuitousItalian Italian]] for "silver", as in silver crosses. She even wears one in her introductory arc before being revived as a devil.
* TheMedic
** ShootTheMedicFirst: [[GenreSavvy Something the group always prevents.]]
* NamesTheSame: To Creator/AsiaArgento.
* NiceGirl: Asia is possibly one of the kindest characters in the series as she still believe in Issei despite being a pervert and still prays to God despite becoming a devil.
* NoPronunciationGuide: In the dub, Issei's father pronounces it the way one says it the English manner (A-ja), while she corrects him in that it's AH-zyah.
* ParentalAbandonment: According to her {{backstory}}, her parents left her behind at a church doorstep, thus leading her to be...
** RaisedCatholic: See above.
* [[spoiler:PowerAtAPrice: For Fafnir to follow her instructions, he just needs a treasure. [[PlayedForLaughs Unfortunately for Asia, it's her panties.]]]]
* SpellMyNameWithAnS: Some scanlations often use "Aashia" and "Ashia". Some early promotional material didn't help solve this issue either until they resolved it with her current name.
* SummonMagic: This is what Azazel advices to Asia so she could catch up with the rest of the team. [[spoiler: [[ItWasAGift So he gives her Fafnir.]]]]
* SupremeChef: Out of all the harem, Asia is believed to be the best in cooking.
* TomboyAndGirlyGirl: The girly girl to Xenovia's tomboy.
* [[TouchedByVorlons Touched by Ophis]]: Is blessed by Ophis to be able to make pacts with Dragons, the first is Fafnir. (Rassei doesn't count as he is a Familiar).
* {{Tsundere}}: Not her, [[spoiler:''her breasts''! Yes, Issei used [[PowerPerversionPotential his new ability]] to hear what a girl's breasts are saying.]]
* UndyingLoyalty: After falling in love with Issei, Asia swears that she will always stand by Issei's side forever, and in demon years that is in the thousands. She even declares to join Issei's Peerage when he becomes a High-Class Devil.

!!Akeno Himejima
->'''Role:''' Queen\\
'''Species:''' Human-Fallen Angel / Reincarnated Devil\\
'''Voiced by:''' Creator/ShizukaIto (Japanese) and Teri Rogers (English)

Rias' confidant, subordinate and fellow member in the Occult Research Club, Akeno is a half-human, half-fallen angel [[spoiler:with a grudge against her father, Baraqiel, for her mother's death, joining Rias to exact revenge]].
* TheAce: She is quite skilled and adaptable in combat, to the point that even some of the other characters are fearful of facing her due to her abilities as well as her queen ranking.
* ActionGirl
* ADayInTheLimelight: Volume 7 is spent mostly on her character, as well as her family issues.
* BerserkButton: Hurt Issei in front of her, and she goes nuts.
* BloodKnight: Enjoys combat a little ''too'' much for comfort.
* BunnyGirl: Dressed up as one to [[spoiler:attract Issei's clones. Naturally, they all fall for it, hook, line and sinker]].
* [[spoiler:CallingTheOldManOut: One of the reasons she joined Rias' group.]]
* CatFight: She does this with Rias a lot once she falls for Issei too.
* ChefOfIron
* CombatSadomasochist
* CoolBigSis: To the Occult Research Group and by extension, to the entire Academy.
* DarkAndTroubledPast: Oh ye ''gods''. Her's is possibly the worst of the bunch.
* DissonantSerenity: How could she be ''giggling'' after killing someone?!
* {{Dominatrix}}: Invokes this for some of her contracted 'clients'.
* DullEyesOfUnhappiness: PlayedForDrama at the start of Volume 12, following [[spoiler:Issei's (temporary) death]]. PlayedForLaughs in the {{Hot Springs|Episode}} short story, when she [[spoiler:walks in on Grayfia and Issei, coming to the assumption that she [[NotWhatItLooksLike has a "real affair"]] with him, and drops on the floor with hollow eyes]].
* ElementalPowers
** ShockAndAwe
** LightEmUp: Her Holy Lightning, which she inherited from her father. She initially hates using these powers until Issei convinces her otherwise.
* [[VampiresAreSexGods Fallen Angels Are Sex Gods]]: In universe, female Fallen Angels are renowned for having very seductive bodies and her naturally sexy disposition, plus having the largest breast size in the series so far, only enhances this fact. Azazel himself states that Akeno is seductive even for a Fallen Angel.
* FirstKiss: Somewhat with Issei, as she just touch his lips with her lightly.
* HairAntennae: A rather unique variant in which they slope backwards, rather then forwards.
* HeroicBSOD: [[spoiler:After Issei's (temporary) death, she was seen lying on the sofa, arms limping, devoid of life in her eyes and not responding to Kiba's attempts to talk to her.]]
* HeroicSeductress: Rias makes a comment that Akeno would make an excellent succubus. Noted that she only desires to sex up Issei.
* HopeSpot: Gave one towards [[spoiler:the [[MesACrowd Issei clones]]]] before decimating them with her magic.
* [[spoiler:[[IHateYouVampireDad I Hate You, Fallen Angel Dad]]: Until they both resolve it.]]
* InstantAwesomeJustAddDragons: [[spoiler:After taking in so much of Issei's ki from sucking all that power whenever Issei needs to have his arm back to human form, her powers have evolved to the point that they are dragon-shaped. Let's just say mayhem ensues even more now.]]
* ItRunsInTheFamily: Technically, Akeno is a sadomasochist, meaning she can switch between being the giver or taker depending on the situation. She got the masochism from her father, and the sadism from her mother.
* {{Miko}}: Dresses as one when it's time to get really serious. She inherited it from her mother.
* TheMistress: What she wants to be for Issei. She even actively pursues this. Rias is very aware of her 'plan' and is NOT happy. [[spoiler:She is crushed when [[NotWhatItLooksLike it seems]] Grayfia is one for Issei.]]
* NinjaPirateZombieRobot: A {{miko}} who is also a fallen angel and a devil.
* NumberTwo: She is the first servant and friend Rias made in the human world.
* OneeSama: Referred to as one of the Two Great Ladies of Kuoh Academy.
* RapunzelHair
* RavenHairIvorySkin
* RedBaron: "[[{{Miko}} Priestess]] of Thunder", and later [[spoiler:"Priestess of Lightning" after mastering Holy Lightning.]]
* {{Romanticized Abuse}}r: A bonafied sadist, unless it's Issei, at which point she becomes the masochist for him and only him.
* SexIsViolence: As noted under BloodKnight above, Akeno ''really enjoys combat''. Some of the [[ expressions]] she wears in the manga go well beyond "suggestive".
* {{Sexophone}}: Almost played straight in Season 2, when Issei has to have his excess dragon ki [[IntimateHealing 'removed' by Akeno]]. As soon as she enters the room, the music starts... Plenty of [[VisualInnuendo finger sucking]] to be had.
* SkinshipGrope: Gropes Rias at the swimming pool of the Gremory household. She also gives quite a few to Issei as well.
* StepfordSmiler: She is usually smiling. However, bring up her DarkAndTroubledPast, or [[BerserkButton harm Issei]], and she'll go nuts on you.
* {{Stripperiffic}}: Her Fallen Angel Mode.
* TheTease: Oh so ''much''. As this is her default setting, even normally innocent teasing can taken as flirty.
** As her love for Issei blossoms, she eventually no longer teases him, but flirts with genuine desire for lovemaking.
** One of the first season's short specials ''entirely'' revolves around her teasing Issei. [[spoiler:Turns out it was {{all just a dream}}.]]
* VerbalTic: "Ara ara~" (Oh my~).
* VirginPower: Took advantage of this to lure the {{Unicorn}} go near her. [[spoiler:[[HilarityEnsues She then smacks said unicorn and the group takes the unicorn's horn.]]]]
* YamatoNadeshiko: When not in sadist mode, Akeno come off as a ideal Japanese woman due to her long black hair and gentle smile. Not to mention she is a great cook like Asia and Rias. Akeno is also polite and devoted to Issei and her team. However, Akeno has a fragile personality to her as she "depend" on men due to her sad past.
* YinYangBomb: She is a Human/Fallen Angel hybrid turned Demon.

!!Yuto Kiba
->'''Role:''' Knight\\
'''Species:''' Modified Human / Reincarnated Devil\\
'''Voiced by:''' Creator/KenjiNojima (Japanese) and Sean O'Connor (English)

The school prince of Kuoh Academy and Issei's self-proclaimed best friend, Yuto was the lone survivor of a failed project which used a group of children to wield holy swords, and swore revenge on those who disposed him and his friends.
* TheAce: Has lots of fangirls compared to the unpopular Issei, plus he is intelligent and quite powerful. [[LampshadeHanging Lampshaded]] in the ending theme of the Season 1 anime. There's a playing card theme, and Kiba is shown as the Ace of Spades. Also a really good {{Foreshadowing}} too.
** BrokenAce: Despite his cool appearance, it is shown in Volume 3 that Kiba has an obsession with revenge, which makes him hot-tempered and irrational.
* AchillesHeel: He realizes that if his legs are damaged, he'll lose overall combat performance. [[spoiler:And it shows during his fight against Siegfried.]]
* ADayInTheLimelight: Volume 3 highlights Kiba; delving into his dark past.
* AmbiguouslyGay: A lot of his later interaction with Issei puts his true sexuality in question (at least in the latter's head).
* ApologeticAttacker: Apologizes to his enemies whenever Issei breaks out a new perverted technique, much to the latter's frustration.
* {{Badass}}
** [[spoiler:HandicappedBadass: Had one of his arms sliced off by Siegfried. He still kept on going, especially after Siegfried pushed his BerserkButton.]]
** HeartbrokenBadass: Thanks to one DarkAndTroubledPast.
* BeautyMark: Under his left eye.
* BerserkButton: Back in the day, if you present to him a holy sword, watch as he goes batshit insane. [[spoiler:Later, mocking Issei's sacrifice to save Ophis as futile becomes a one-way ticket to a brutal beatdown.]]
* {{Bishonen}}
* BondOneLiner: Delivers an epic one to [[spoiler:Freed, after impaling the latter's head with his sword.]]
-->"You can continue howling to the Grim Reaper in Hell."
* BrokenBird: Male example, in which he still feels the pain of being experimented upon back during his childhood, even well into adolescence.
* BrosBeforeHoes: This is the [[AlternateCharacterInterpretation counterargument]] to Kiba's HoYay tendencies. May even cross with BromanticFoil.
** HeterosexualLifePartners: It is noted that Kiba does show ''some'' interest in the opposite sex, he just considers his friendship with Issei more important.
* ChickMagnet
* CovertPervert
* DarkAndTroubledPast
* DualWielding: And sometimes, ''[[CutlassBetweenTheTeeth triple]]'' wielding.
* ElementalPowers: His swords can do this.
** PlayingWithFire
** AnIcePerson: Flame Delete
** CastingAShadow: Holy Eraser
** YinYangBomb: His holy demonic swords, which are compared to a glitch.
*** Took this trope literally in Volume 12 when [[spoiler:he briefly wields Issei's Ascalon, a holy sword, and Siegfried's Gram, a demonic sword]].
* FirstPersonSmartass: Not as much as Issei, but he does have his moments whenever he narrates.
* FragileSpeedster: By his own admission. And Issei points out later that Kiba's not blocking his attacks anymore whenever they spar.
* [[spoiler:GenderBender: In one Volume 13 short story, the entire group (minus Issei) underwent a gender change via Azazel's gendar-swapping raygun. [[ This is Kiba's]]... and to Issei's horror, he realizes [[StupidSexyFlanders "she" is]] [[AttractiveBentGender his type of girl]].]]
* IdiotHair
* ILikeSwords: Some of them include:
** BlackSwordsAreBetter: Holy Eraser, again.
** CoolSword: ''Lots of them''. [[spoiler:[[UpToEleven Even more now]] after ''all'' of Siegfried's swords answer to him.]]
** CutlassBetweenTheTeeth: ''Triple wields'' demonic swords against Kokabiel. Must be taking lessons from [[OnePiece Zoro.]]
** FieldOfBlades: Sword Birth. Amplifying it with Issei's [[StatusBuff Gift]] gives him ''even more swords popping out'', and it gets taken UpToEleven with [[spoiler: Xenovia's Durandal]].
* [[spoiler:IOweYouMyLife: After Issei saves him.]]
* LikeBrotherAndSister: Has this relationship with Koneko.
* [[spoiler:MesACrowd: His ''second'' Sacred Gear when it was known that a user only gets to use one Sacred Gear at most.]]
* NiceGuy: Despite Issei's initial rudeness towards him, he still is as polite and even encourages Issei more so than the rest of the Occult Club with the exception of Rias.
* OhCrap: When Issei first fired his Dragon Shot on him when they were training. He made it. His wooden sword? Not so much.
* OnlySaneMan: When [[DatePeepers club members were spying]] on Isse's date with [[spoiler: Akeno]]. He was the only one who didn't bother with ridiculous PaperThinDisguise (like hat with sunglasses, or wrestler mask) or even trying to remain hidden, and waved hand at him as if he was saying "sorry about this".
* TheMindIsAPlaythingOfTheBody: While Yuto is very ambiguous as a male, when he genderbends to Yumi, the attraction towards is that much more apparent.
* MrFanservice: Unlike Issei, Yuuto's body is very muscular and fit from the start, plus he wears a pretty tight speedo when swimming or at the beach.
* ThePromise: Issei made him promise that if one of them dies, then they'll have to fight harder for the sake of the one who died. [[spoiler: And then Issei did die ([[DeathIsCheap temporarily]]), making Kiba fulfill that promise.]]
* RedOniBlueOni: The blue to Issei's red.
* {{Revenge}}: His entire reason for becoming a devil under Rias' service is to find and destroy all the holy swords.
* [[spoiler: StepfordSmiler: Throughout the first part of volume 12]].
* SwitchingPOV: Occurs in several chapters of the Light Novels where the story is told from his viewpoint over Issei's; The first switch occurring in volume 3 during the chapter he gains Balance Breaker in the fight against Kokabiel.
* WeakButSkilled: Let's have a checklist: excluding Asia, his best friend is the incarnation of destructive power and all-around badass, his president and vice-president can mow down armies, his fellow club member can create explosions from her {{BFS}}, his two juniors, one capable of punching somebody so hard they get knocked out and the other being able to stop time, and his teacher can bombard enemies with magic. Him? Sure he can create any kinds of swords from out of nothing, but other than that, he mostly uses his speed. And yet he's the second most powerful member of the group. He even lampshades that he's the only technique user in a group full of power-types.

School mascot of Kuoh Academy and one of Rias' earliest members. She's in the care of the House of Gremory after [[spoiler:her older sister Kuroka killed their master. Not wanting to become like her, she's sealed most of her powers until Issei convinces her otherwise]].
* ACupAngst: She reacts violently when Freed calls her a "little girl." She explains that she feels this way about herself [[spoiler:when offering to [[IntimateHealing restore Issei's lifespan with senjutsu via sex]]]].
** In volume 3 she even states that not being looked at pervertedly gives her complex feelings.
** [[spoiler: Not the case anymore if volume 16 is accurate.]]
* ADayInTheLimelight: Volume 5 is dedicated to developing Koneko, and the troubles she has controlling her senjutsu powers.
* AnimalJingoism: She has a cat motif, while Ravel has a bird motif; cats and birds [[VitriolicBestBuds generally get along poorly]].
* BadassAdorable
* BerserkButton: Don't call her "[[ACupAngst little]]" or she'll throw things at you. ''Lots'' of them, in rapid succession.
** PervertRevengeMode
* CantCatchUp
* CatsAreSnarkers
* CatGirl: In thematic appearance as well as actual lineage.
* CharacterDevelopment: Initially harsh to Issei, witnessing his determination and strength eventually helps her warm up to him, to the point where [[spoiler:she falls in love with him and once even suggested having sex with him]].
* CrutchCharacter: She ends up as the weakest combat unit, [[spoiler:and eventually asks Kuroka for help to get stronger]].

* DefrostingIceQueen: Zig-zagged.
* GlacierWaif
* HiddenDepths: [[spoiler:She's a fan of rapping and shows it off to Issei.]]
* HeroicRROD: Her [[spoiler: Shirone mode]] counts as after a few minutes she is exhausted. Although Azazel claims that with time, it won't be a problem.
* IntimateHealing: She does this for Issei [[spoiler:in order to recover his lifespan]]. The fact that she does it happily is a sign of her growing feelings for him.
* JailbaitWait: Issei [[InvokedTrope implements]] this on her for her own safety, because were she to have a child with him at her current size, it would spell disaster for her and their unborn child.
* LikeBrotherAndSister: With Kiba.
* LittleMissSnarker
* MeaningfulName: Koneko is a good name for a CatGirl as it is Japanese for "kitten" (more literally "child cat"), while her surname means "castle", befitting her positon as Rook.
** [[spoiler:MeaningfulRename: Koneko isn't her real name, rather it's Shirone, itself meaning "White Sound".]]
* MightyGlacier
* PigeonholedVoiceActor: Once again, Creator/AyanaTaketatsu is [[Manga/KOn associated]] [[LightNovel/MayoiNekoOverrun with]] [[LightNovel/OreNoImoutoGaKonnaNiKawaiiWakeGaNai cats]].
* PintsizedPowerhouse: Size inversely proportionate to her titanic strength. Justified because her [[ChessMotifs Evil Piece]] is a Rook, which gives her [[SuperStrength incredible strength]] [[MadeOfIron and defense]].
* ReiAyanamiExpy: Pale, soft-spoken, silver hair, petite...although she's the one dealing out the slapstick violence to Issei most of the time, which is highly atypical of this trope.

* SugarAndIcePersonality
* [[spoiler:SuperMode: "Shirone Mode" in volume 16, [[SheIsAllGrownUp in]] [[BreastExpansion more ways]] [[OlderAlterEgo than one]].]]

A former exorcist, Xenovia first appears in Volume 3 alongside Irina to find pieces of Excalibur stolen by a fallen angel.
* ActionGirl
* AttackAttackAttack: Something Kiba notes that she really needs to get out of. [[spoiler:Which finally happens in Volume 14.]]
* BadassCape
* {{BFS}}: Durandal is a pretty big sword.
* BookDumb: Subverted; she's one of the smartest at her class much to Issei's surprise. This is even more impressive since when she first started attending Kuoh, she wasn't even literate [[note]]Literacy in Japanese involves being able to read not only the "alphabet", but also the 100 most common Kanji (of thousands)[[/note]] and mentions pulling all-nighters so she can learn to read the classwork properly.
** StudentCouncilPresident: The main reason why she wants to be a DumbassNoMore.
* BoyishShortHair
* CharacterDevelopment: Initially rude to Asia, herself a former follower of God, until she eventually mellows out to her to the point of becoming [[CoolBigSis an older sister surrogate]].
* {{Cloudcuckoolander}}: Lacks a lot of common sense.
* ContraltoOfDanger: Her normal voice, made even more evident when she practiced "how to be a normal teenage girl"
--> '''Xenovia:''' (Voice several pitches higher than her usual coarse-and-masculine contralto) Let's get along, 'kay, Issei-kun!
--> '''Issei:''' That cutesey voice does NOT suit you!
--> '''Xenovia:''' (Switches straight back to her normal-unfeminine voice) I know, I tried to copy Irina, and it was SO difficult.
* CoolSword: Current wielder of Durandal.
* CovertPervert: The "pervert" part is undeniable. The "covert" part is at best paper-thin. During the short story "300 Isseis", when [[spoiler:one of his clones (whom she thought was the real Issei) used Dress Break on her, she got angry not because she got stripped, but because he didn't do anything else to her]].
* DangerouslyGenreSavvy: When she first runs into Issei and Asia, she seems to know quite a bit about the latter, such as her having been a saint turned devil. She also mentioned that she was in town to retrieve some holy swords that were stolen by fallen angels, and wanted Rias to promise not to interfere.
* DoYouWantToCopulate: She wastes no time in letting Issei know that she wants his genes. She even has condoms on hand for whenever he wants to 'practice'.
* DualWielding: Usually wields Durandal but sometimes she wields it alongside [[spoiler: Ascalon whenever Issei lends it to her.]]
* DumbMuscle: A debatably accurate accusation often leveled towards her, much to her annoyance. She entirely lacks finesse or technique in combat, and just powers through, making her the exact opposite of dexterity-oriented Kiba. [[spoiler:This leads to a hilarious subversion in Volume 14, when she starts using different Excaliburs. Kiba actually starts shedding tears of joy, and the attacking magicians are dumbstruck that the "power idiot" can use techniques.]]
* EarlyBirdCameo: She made a brief appearance in the post credits of Season 1 during the announcement for ''W''.
* EvenTheGirlsWantHer: Accumulated a lot of fangirls during the Rating Games.
* FaithHeelTurn: [[spoiler:Subverted -- even after Rias' team, she still retains her faith in God.]]

* InTheHood: Her cape features this.
* MamaBear: [[spoiler:When Asia is taken by Diodora, she ''vaporizes'' two devils who got in her way.]]
* [[spoiler:MorphWeapon: Knows how to use Mimic thanks to Irina.]]
* MurderIsTheBestSolution: Done with any talks before the fight? She'll fire off the first blow before anyone else, much to Issei's consternation.
** She ''really'' wanted to kill Diodora. Shalba beat her to it.
* NoSocialSkills: Talks about condoms and having babies to Issei ''out loud'' in front of ''everybody''. Needless to say, she doesn't have the slightest social grace.
* PillarOfLight: What happens when she combines Durandal with Ascalon.
* RaisedCatholic: Like Asia, she was also raised in a Catholic church, hence her lack of experience with the real world.
* SpellMyNameWithAnS: Xenovia or Zenobia?

* TomboyAndGirlyGirl: Is the tomboy compared to Asia and Irina.
* VaporWear: Revealed by Irina.

Issei's childhood friend, she first appears in Volume 3, returning to Japan to look for the Excalibur swords alongside Xenovia.

She then joins the club in Volume 6, reborn as an angel in the service of Michael under the designation of "Ace of Spades".
* ActionGirl
* ADayInTheLimelight: Volume 18 is dedicated solely to her which finally explores her childhood relationship with Issei.
* BerserkButton: She used to laugh it off, but now she gets ticked off when someone puts "Self-Proclaimed" in front of any of her titles. Especially angel and childhood friend.
* BigDamnHeroes: Brings a projector that contains the Breast Dragon song [[spoiler:[[ChekhovsGun Issei had to rehearse midway through Volume 6.]]]]
* BoyishShortHair: As a child, as shown in the manga.
** TomboyishPonytail: In the anime.
* ChildhoodFriends: With Issei. Whether she's going to be victorious or not is another story, however [[WordOfGod the author]] [[VictoriousChildhoodFriend did promise that everyone was going to get a happy ending though...]]
** In Volume 14, Issei comments on how he usually forgets that Irina really is his childhood friend, while Xenovia uses this as a chance to call Irina the self-proclaimed childhood friend. Later, [[spoiler:despite her inner conflict between sleeping with him and refusing to become a fallen angel, she mentions that there is a way for her to sleep with him without her turning into one but on the condition that they're thoughts must remain chaste, among a few other things, while Issei comments how impossible it would be for him to refrain from thinking lewdly while doing such a thing.]]
* {{Cloudcuckoolander}}: Like Asia and Xenovia.
* ComicallyMissingThePoint: What does she say when she sees [[spoiler:Issei groping both Xenovia and Asia?]]
-->"G... Go do it on a bed! This is too dirty, and the hygiene is terrible in this place!"
* CoolSword: she uses [[spoiler:an artificial version of Kiba's Holy-Demonic Sword]].
* {{Fangirl}}: She and Issei used to be SuperSentai fans to the point she would pose just to mimic her favorite heroes. She's pleased when her childhood friend gets to have a TV series of his own.
* FirstKiss: [[spoiler: With ''Issei'' back when they were kids.]]
* ForgottenFriendNewFoe: When they have first met again after many years, she was conflicted between kill or sparing Issei, since she's an exorcist and he's a devil. After the PeaceConference. however, this is no longer an issue.
* GenkiGirl
* GirlishPigtails
* IdiotHair
* MaliciousMisnaming: It's a sore point for her if people keep referring to her as a "self-proclaimed angel".
* MorphWeapon: Her Excalibur Mimic. Though she usually keeps it as a [[KatanasAreJustBetter katana]] for simplicity. She later teaches it to [[spoiler:Xenovia]].
* OneOfTheBoys: Used to be a troublemaker like Issei back when she was a kid. So much so the latter was shocked when he discovers, many years later, [[UnsettlingGenderReveal that his "best friend" is a girl all along]].
* ProperTightsWithASkirt: As part of her school uniform.
* {{RaisedCatholic}}/ChristianityIsCatholic: Both are averted hard as she's explicitly stated to be Protestant.

'''Voiced by:''' Creator/RikiyaKoyama

Formerly the leader of the fallen angels, he first appears in Volume 4, when Issei mentions that he's one of his primary contractors. He then joins the club as advisor at Souna and Sirzechs' suggestion.
* TheAce: He's a MadScientist that reached several breakthroughs with Sacred Gears and even created an artifical Sacred Gear. He's also an exceptional {{Badass}} and [[AuthorityEqualsAsskicking leader of the fallen angels]]. To top it off, he's an [[AllGirlsWantBadBoys extremely successful ladies' man]]. Needless to say he could be called perfect in every way.
* AllGirlsWantBadBoys: How he's described by Issei.
* TheAtoner: Part of his reason for pushing for the peace conference is the fact that he still blames himself for the unintended consequences of his past orders, such as Reynalle killing Issei (whereas his original order was for her to simply spy on him) and [[spoiler:Shuri being killed wile her husband, Baraqiel, was on a mission given by Azazel himself, causing friction between him and his daughter Akeno. When father and daughter reconcile, he silently thanks Issei for helping him lift that burden]].
* {{Badass}}: Anyone who could hack their arm ''without flinching'' has gotta be hardcore.
** AuthorityEqualsAsskicking: Well, he ''is'' the leader of the Fallen Angel faction. [[spoiler:At least, until he retired.]]
** BadassBeard
** BadassTeacher
** BadassTransplant: Replaces his missing arm he cut himself into a robotic arm that he's always wanted to try out.

** StaringDownCthulhu: Confronts Indra -- a god.
* BunnyEarsLawyer: Like you would never believe.

* CombatCommentator: For the Ratings Game match between Team Gremory and Team Bael.
* CoolCar: Even has an ''anti-Dragon missile and a KillSat''.

* LargeHam: When he has Rias "[[ItMakesSenseInContext in hostage]]".
** EvilIsHammy
* LaserGuidedKarma: He finally gets his comeuppance after making Issei a ButtMonkey, oh so many times, by the entire group. HilarityEnsues.
* MadScientist: He's devoted to studying Sacred Gears. [[spoiler:He got excited after seeing the Nemean Lion Regulus and ''demands'' to Sairaorg to bring that to his lab for studying.]]
* MajorInjuryUnderreaction: He hacks off his arm using his light attack that supposedly is dangerous for him. He ''just brushes it off'' like it's nothing.
* [[spoiler:MistakenForTerrorist: He's accused of hypocrisy due to being a "terrorist" while suing for peace. Needless to say, he's not amused.]]
* MulticoloredHair: His hair fades to a lighter color at the front.
* NiceJobBreakingItHero: [[spoiler:Inviting Ophis to Issei's house in hopes that there will be peace could be one, except it was the lesser of two evils. Had he not accepted Vali's request, worse could have happened with TheAlliance and they would have never been able to gain Ophis as an ally.]]
* NotSoStoic: After seeing Rizevim, he ''destroys a wall'' to show how frustrated he is at seeing him.
* OhCrap: When he realizes [[HilarityEnsues he's getting ganged up by the group for starting the entire mess]] of the Issei clones.
** A more serious one happens when he finds out that [[spoiler: Rizevim is now the leader of Khaos Brigade.]]

'''Species:''' Dhampyr / Reincarnated Devil\\
'''Voiced by''': Ayane Sakura (Japanese)

Rias' first Bishop and an extremely effeminate {{dhampyr}} who doesn't even want to suck blood.
* AchillesHeel: Garlic
* ADayInTheLimelight: Including Volume 4, which took a majority for his introduction, Volumes 14 and 16 revolve around him, and his background, in the Romanian vampire society.
* AllOfTheOtherReindeer: Born of a vampire nobleman and a human woman, Gasper's social life on either side of his lineage is... crapsack, to say the least. Unlike other demon races, vampires value hereditary purity over familial ties, thus he is often the target of discrimination. As a human he fares no better, being feared and despised for his powers.
* BadassAdorable
* BewareTheNiceOnes: [[spoiler:He was kept in the dark about Issei's (temporary) death, because it would be too traumatic. Then Georg just had the gall to taunt him about how senseless Issei's sacrifice to save Ophis was. Cue Gaspar losing it in a grisly scene seemingly ripped straight out of ''Manga/{{Hellsing}}''.]]
* ChekhovsGunman: Rias had stated back in Volume 1 that she had already used a Bishop piece when she revived Asia. He makes his first appearance in the middle of Volume 4.
* CurbStompBattle: Happens anytime he uses his Sacred Gear powers. [[spoiler:And when he uses ''his true powers'', Kiba outright narrated that his fight against Georg wasn't even a fight at all.]]
* DudeLooksLikeALady: Taken UpToEleven in the anime, complete with a incredibly cutesy tone that barely betrays his true gender.
* EarlyBirdCameo: Like Xenovia, he also made a brief appearance in the Season 1 anime's post-credits during the announcement for Season 2.
* EvenTheGuysWantHim: Somehow was able to collect fanboys despite knowing that he's male.
* {{Expy}}: Of one [[Manga/JoJosBizarreAdventure Dio Brando]], really -- both are androgynous blond male vampires lusted after by ''men'' in spite of their gender, with the fearsome ability to [[TimeStandsStill stop time at will]], but replacing Dio's [[{{Jerkass}} completely reprehensible personality]] with an adorably sweet one.
* FragileFlower
* FriendlyNeighborhoodVampire
* GlowingEyesOfDoom: When he drinks Issei's dragon blood, his full power manifests.
* HeartBrokenBadass: [[spoiler: When he finds out that Issei died, and when he finds out that Valerie Tepes, his best friend, is in a coma after overusing the Holy Grail.]]
* {{Hikikomori}}: Of the agoraphobic variety, to the point that unless inspired by Issei, he will jump into a cardboard box he brings with him at the drop of a hat. Sometimes before the hat drops as well. Issei remedies this by giving him a paper bag with eye holes to help him with this, only for him to quip that Gasper looks like a pervert.
* NoSocialSkills: Thinks crossdressing is perfectly acceptable.
** WholesomeCrossdresser: Not that anyone would know if they were not told.
* NiceGuy
* OurVampiresAreDifferent: A cross-dressing vampire to be exact.
* RedEyesTakeWarning: He looks like he wouldn't harm a fly [[spoiler:until he loses it against Georg]].
* [[spoiler: {{Sealed Evil In A Can}}/SealedInAPersonShapedCan]]: [[spoiler: It's revealed that Gasper's version of Forbidden Balor View contains an actual fragment of the Irish evil god Balor from which the Sacred Gear takes it's name.]]
* ShrinkingViolet
* StupidSexyFlanders: Issei can't seem to think of him as a guy, seeing as he covers himself in a towel from the chest.
-->'''Issei:''' "What a cruel reality!"
* SuperpowerLottery: There's a ''reason'' why his Bishop piece is mutated. {{Lampshaded}} by Issei, when he complains about how broken stopping time is. [[spoiler:And that's not even counting what he can do ''without Forbidden Balor View''.]]
* [[spoiler:TakingTheBullet: In Volume 10, when Xenovia's ability was sealed during the Gremory-Bael Ratings Game, he used his body as a shield to protect her.]]
* TenderTears: One of the reason Issei just can't stop going StupidSexyFlanders over him.
* TheSoCalledCoward: Normally, he'd be afraid to do almost anything without Issei's help. [[spoiler:Until he decides to take a hit for Xenovia, and later when he flips against Georg]].
* TimeStandsStill: His Sacred Gear, Forbidden Balor View.
* VegetarianVampire
* [[WhyDidItHaveToBeSnakes Why Did It Have to Be Garlic?]]: One of his main weaknesses, something Issei notes that he needs to get out of.
* ZettaiRyouiki: Grade A

* BodyguardingABadass: There should have been no reason why Odin needed her at all [[BadassInCharge considering what he can do.]]
* [[CantHoldHisLiquor Can't Hold Her Liquor]]: One cup of sake leads to slurred speech, and two leave her with a hangover, [[VomitDiscretionShot sufficiently non-detailed nausea]], [[AlcoholHic hiccups]] and a staggered stumble.
* ChristmasCake: Constantly teased by Odin about this, despite the fact that she's just about as old as the rest of the Club.

* ShoutOut: Rossweisse is the name of one of the Valkyries featured in ''[[Theatre/TheRingOfTheNibelung Der Ring des Nibelungen]]''.
* {{Valkyrie|s}}
* {{Yandere}}: At least according to Issei's description of her after chasing down Odin in Volume 10.

!!Ravel Phenex

'''Species:''' Pure Devil\\
'''Voiced by:''' Asuka Nishi (Japanese) and BrittneyKarbowski (English)

Riser's youngest sister, first appearing at Rias' first Ratings Game where she was a Bishop, but hardly did anything at all. In Volume 10, she transfers to Kuoh Academy as a first-year, being placed in the same class as Koneko and Gasper, much to the former's frustration.

* BreastExpansion: In recent volumes. See YourSizeMayVary below.

* HotWings: Like Riser, she also has the ability to sprout these.
* MegaTwintails
* {{Ojou}}
* NoblewomansLaugh: Does this briefly in chapter 20 of the manga, complete with pose, only for Issei to walk past her to her frustration.
* [[NonActionGuy Non-Action Girl]]: As of recent, she hasn't really done anything.
** In battle, at least. In one of the Volume 13 chapters, she sends Issei flying into a mountain when he "accidentally" sees her bathing while he was trying (and barely succeeded) to stop Raiser from DELIBERATELY peeking on Rias, Akeno, AND Ravel.
* {{Phoenix}}: Her animal motif, which fits her surname.
* PlayingWithFire
* ReligiousAndMythologicalThemeNaming: Her surname comes from the 37th of the 72 demons of the Literature/ArsGoetia, which is, as its name implies, a phoenix.
* SpoiledSweet: Seems just spoiled at first, but the sweetness manifests when she falls in love with Issei.
* SupremeChef: Can cook cakes just fine.
* SweaterGirl: [[spoiler:After transferring to Kuoh Academy in Volume 10.]]
* SweetTooth: See SupremeChef above.
* TheSmurfettePrinciple: The only female child of the Phenex family.
* {{Tsundere}}: Type B
* VitriolicBestBuds: With Koneko, via AnimalJingoism.
* [[YourSizeMayVary Your]] [[BreastExpansion Breast Size]] [[YourSizeMayVary May Vary]]: Some illustrations of her either depict her flat-chested or with breasts nearly the same size as Asia's (pictured above). The [[WordOfGod Official Data Book]] later has it that her chest is actually 2cm below Xenovia's, and that her shifting sizes were due to artist error.
