Highschool DxD



""Are you serious! I'm able to make my own harem? I could have sex with them as well right?"

"Yes. I think it's fine if it’s with your servants."

I felt a shock going through my body. Absurd! Something like that is actually possible? In the real world and also as a human, it is really hard to build your own harem. If I was still an ordinary human, no matter what I'd do, I won't be able to get a batch of girls since right now I'm in a bad position.

I don't even have a single girlfriend. Well I did, but I was killed by my ex. But now! Now I can...!

"Oooohhhh yeaaah!! Being a devil rocks! Hell yeah! I can't calm myself anymore! I probably can throw away my porn!""

Remember your first date and how much it sucked, what with nervousness, lack of ideas as to what to do, and running late when you thought you came in early? Well, Issei Hyoudou has you beat. Okay, his first date started out well enough -- in fact, 99% of it was awesome. It's just that the other 1% involved his girlfriend stabbing him in the stomach and leaving him to bleed to death.

Enter Rias Gremory, his school's beautiful, crimson-haired sweetheart. She's also a demon queen, who resurrects him. Without knowing what became of him, Issei returns to his normal life of watching porn, peeking into changing rooms and interacting with his two fellow perverts. But no sooner had he started reconnecting to his old life than a fallen angel attacks him, only to be saved once more by Rias -- now accompanied by two of her faithful servants, Akeno Himejima and Koneko Toujou.

The next day he wakes up naked, right next to an equally naked Rias, who then tells him that she has saved him by turning him into a demon, and is now under her employ. With a promise of power, glory and his very own harem, Issei doesn't mind the tradeoff and quickly jumps onto the prospect. To this end he joins the Occult Club, consisting of himself, Rias, Akeno and Koneko, as well as Asia Argento, a girl raised in a church, and Yuuto Kiba, the school's charismatic prettyboy.

An ongoing 2008 Light Novel series by Ichiei Ishibumi and illustrated by Miyama-Zero, High School DxD is a series that runs away with all the gratuitous Fan Service and one boy's slow ascent up the ranks of the demon world. It also has an ongoing 2011 manga series illustrated by Hiroji Mishima and a Winter 2012 Anime adaptation.

There is also a Lighter and Softer Spin-Off of this series, starring Asia and Koneko called "High School D x D: Asia and Koneko's Secret Contracts".

Baka-Tsuki has a translation project for the Light Novels.

FUNimation also has licensed the anime. You can watch it here at Funimation or here at Nico Douga. They're censored though.

The series is decidedly NOT about high-schoolers playing Dungeons and Dragons.

"Familiar Master: Tsukaima, Getto da ze!
 * Abuse Is Okay When Its Female On Male: Downplayed since it's only Koneko who attacks him.
 * Action Girl: So far almost all female devils (except Asia) are pretty good at ass-kicking anyone with either physical or magical attacks.
 * World of Action Girls
 * Accidental Pervert: Generally there's nothing accidental about the situations Issei gets caught in, but that time his mom found him sleeping naked next to Rias was totally innocent.
 * Almighty Janitor: Issei himself is this seeing as Rias had to use all 8 of her pawn chess pieces to even have him as a servant. Saji is also this to a lesser degree.
 * All Just a Dream: The 2nd special episode.
 * All Men Are Perverts: We start with Issei of course, but he's definitely not the most perverted guy ever. The only male character who doesn't seem to even be remotely close as a pervert is
 * All Myths Are True: The Greek and Norse are confirmed in the novels. Heroes such as King Arthur and Cao Cao feature as well.
 * Another Dimension:
 * Ars Goetia: The Gremory and the Phenex family names are in it.
 * A Truce While We Gawk: In volume 7, while an epic battle is going on Issei somehow, yes there is apparently one in the universe. When he announces this everyone on both sides stop fighting and start staring at him as if he's done something stupidly crazy again...
 * Authority Equals Asskicking: If you are a leader of a faction, one of the minimum requirements is that you have to kick ass.
 * Ax Crazy: Freed, full stop.
 * Badass: A lot.
 * Badass Abnormal: Issei. He has a sacred gear but it's noted that he achieved his level of power not because of his sacred gear but because of Training From Hell and his will to never give up. Otherwise he would be far weaker.
 * Badass Adorable: The girls may look beautiful but most of them are strong enough to easily destroy buildings.
 * Badass Crew: You have the Occult Research Club, Chaos Brigade Vali's group, the Kuou Student Council, Sairaorg's team, and then there's
 * Badass Family: The Gremory family. When you've got the Crimson-haired Ruined Princess (Rias), the Silver-haired Queen of Annihilation (Grayfia), and the Brunette Madame of Extinction (Lady Gremory) gunning after you, you might wanna run away pretty fast.
 * Badass Normal: Sairaorg lacks any special power but trained his body hard enough that he can defeat any of the devils in his generation with ease. Only Issei can stand up to him among the new generation of devils.
 * Crouching Moron, Hidden Badass: One would never expect that perverted Ordinary High School Student to be someone that went toe to toe with some of the strongest beings in mythology and won.
 * One-Man Army: Any of the leaders of the factions, Issei plus his rivals, and the Gods.
 * World of Badass
 * Barbie Doll Anatomy: In the anime's opening the girls (most noticeably Asia) have nipples but the crotches of barbie dolls, but early in the manga even Issei lacks nipples, though in the manga the girls use Godiva Hair too. Later in the Manga it's averted.
 * Barehanded Blade Block:.
 * Battle Harem
 * Beethoven Was an Alien Spy: In Chapter 8 of Volume one it's at least heavily implied that Jesus' power came from a Sacred Gear.
 * Bedmate Reveal: At the end of episode 1 has Issei waking up and finding.
 * Beyond the Impossible: How much can Issei power up using Rias' breasts!? How much HSQ are the fights in this series!? Which mythology will be the next one introduced!? What kind of new perverted power up can Issei pull off next!? Yeah it's that kind of series.
 * Big Fancy House: Rias' house in the Underworld
 * Bishounen: Kiba
 * Bishoujo Genre: All of the main girls and most of the supporting ones are attractive women
 * Boobs of Steel: Rias, Akeno.. it's all good.
 * Book Ends: The anime starts and ends with the same scenes, with slight differences.
 * Blood Knight: Akeno is a combat sadist, and
 * Brick Joke: Sirzechs' suggestion to Issei to use Gift on Rias' breasts in Volume 4. Seven volumes later,
 * Bunny Ears Lawyer: Anybody who is in the high ranks are this. Sirzechs, Serafore, Azazel, Odin.. take your pick.
 * Butt Monkey: Compare everyone in the Occult Club and Issei. A good amount of the time Issei is going to take the brunt of some damage from events like sports, rumors, or from Azazel's crazy experiments.
 * Can't Catch Up: Beginning to show shades of this in the Light Novels in regards to Issei and Kiba but especially Issei. They both start off as relatively weak members of the Occult Club with Issei being by far the weakest and Kiba being only around Koneko's level at best. Rias and Akeno at this point were far stronger. Then Kiba and Issei master Balance Breaker and everyone is left coughing in the dust. This is best exemplified when Issei was able to beat Sairaorg Baal using his where as Kiba, enovia and Rossweiss (the three strongest in the occult club with Kiba being by far the stronger of the three) only managed to cut off a arm of Sairaorg  and the rest likely couldn't even scratch Sairaorg.
 * Catgirl: They exist in the universe
 * Chainsaw Good: Raiser's two pawns, who are also twins, uses this against Issei.
 * Chess Motifs: Rias is the King, Akeno is the Queen, Kiba is the Knight, Koneko is the Rook, and Issei is the Pawn. Of course, if you know how pawns work in chess...
 * Chekhov's Gun:
 * Back in Volume 4, Issei absorbed some of Vali's powers by infusing a part of the White Emperor's shard in him, thus being able to use Divine Dividing with only a Million-to-One Chance of it working.
 * Chekhov's Gunman: Quite a few in this series that were mentioned at best make an appearance:
 * Back in volume 1, Asia's past reveals that she healed a devil and that she was exiled from the church. Five volumes later, that same devil reappears in front of Asia
 * Volume 4 has Akeno alluding that she's a half-fallen angel half-devil and that she can never forgive her father. Three volumes later, he makes an appearance.
 * Come to think of it, Gasper is technically one too by Rias alluding that she used her first Bishop piece already back at the end of the first volume.
 * Volume 10 has a boy who couldn't make it into the autograph event and that Issei was able to sign an autograph for him back stage and told him to not cry at all.
 * Chick Magnet: Not so much in the beginning Issei, but after being reborn...so many hot women are after him.
 * According to Ddraig, anybody who possesses the power of dragons instantly becomes a Chick Magnet because apparently, chicks dig power. He even describes to Issei that one of his past users slept with a lot of women.
 * Church Militant: It seems the church in this setting has special squads of assassins and exorcists to deal with the supernatural.
 * Clothing Damage: When Issei first gets his powers the Fallen Angel that's attacking him gets what little clothes she's wearing blown off. And then he gets Dress Break, the ultimate move in a Rating Game where it outright got banned after the first game was over.
 * Clingy Jealous Girl: Asia shows signs of it in volume 3, Rias as well. Then...
 * Competitive Balance: The rating games have this format. Take note however that depending on the individual this could change. For example giving someone fast a rook would make them a Lightning Bruiser instead.
 * Fragile Speedster: Knights.
 * Lightning Bruiser: Queens.
 * Magikarp Power: Pawns could promote into any piece except a King as long as they are in the enemy territory.
 * Mighty Glacier: Rooks.
 * Mission Control: Kings seem to work this way.
 * Squishy Wizard: Bishops.
 * Cool Big Sis: Rias and Akeno are described as this towards the entire school.
 * Cool Versus Awesome: Fights between mythological groups radiate this trope.
 * Crazy Prepared: Issei's fight
 * Crucified Hero Shot:
 * Cute Bruiser: Koneko is adorable enough to be considered a school mascot, and strong enough to punch you through walls.
 * Damned By Faint Praise: In episode 7 Koneko tells Issei that embroidering some headbands is "A feat out side of my expectations".
 * Dancing Theme: The anime ending theme. Ye gods, the ending theme!
 * Dark and Troubled Past: Who knew..
 * Issei proclaims that he has one in Volume 8. It's actually pretty funny.
 * Darkest Hour:
 * Day in The Limelight: More like a volume in the limelight but everyone in the Occult Research Club has their stories centered on a certain volume. Issei and Asia for Volume 1, Rias for Volume 2, Kiba for Volume 3, Gasper for Volume 4, Koneko for Volume 5, Asia again for Volume 6, and Akeno for Volume 7.
 * Defeat by Modesty: Issei's dress break invokes this, sure its mainly used on females but usually its not modesty that defeats them its the heavy handed blasting coming from Issei or one of his teammates as person in question covers their naughty bits.
 * Did We Just Have Tea with Cthulhu?: Odin pays a visit to Issei's house and was hanging out with Azazel.
 * Died in Your Arms Tonight: Before Rias revives Issei.
 * Dirty Coward: After repeatedly grinding the fact that she played with Isse's heart and how his cherished first date with her was a "boring waste of time" into his face, Yuuma STILL reverts to her adorably innocent human form to beg for her life as Isse is about to strike the killing blow. She even sinks so low as to show him the armband he bought her, proclaiming how precious it is to her. Fortunately for Yuuma, Issei, even now, still fondly holds onto those warm memories as cherished moments of love and happiness, and could not bring himself to kill her. Not so fortunately, this only served to anger Rias further for playing with her little-brother's heart like a violin.....
 * Dirty Mind Reading:
 * Disney Death: The climax of episode 10 has
 * Does This Remind You of Anything?: Issei's Boosted Gear has the ability to double the power of the user every ten seconds at the cost of putting strain on the user. Oh the effects can also be stacked. It may remind some people of the Kaio-ken which boosts the users power, speed, defense, ki, etc. The only change produced by the basic Kaio-ken to be quantified in the series is that it doubles the user's power level. The Kaio-ken is also quite taxing on the user's body.
 * Kaio-what?
 * Downer Ending: This is how the past Boosted Gear users lives ended according to a lot of people, foremost being Ddraig.
 * Dude, Where's My Respect?: Averted with Issei. At the start he was treated as a joke by even low tier fallen angels but once he started getting stronger opponents took him more and more seriously.
 * Engagement Challenge: Ok so we knew Rias is engaged to the Phenex household, so Issei when comes to rescue her it becomes this to the people watching it unfold.
 * Everyone Can See It: It is so painfully obvious Rias likes Issei that her father acknowledges him as his future son in law... Same thing applies for Akeno later on, and any savvy reader notices Asia's liking of Issei from the first chapters after she's introduced.
 * Fantasy Kitchen Sink: Humans, devils, fallen angels, angels, Norse mythology, Greek mythology, dragons,, anything you can think of, it's in here.
 * Femme Fatale: Yuuma Amano.
 * Fiery Redhead: Rias in a nutshell, although her power is actually destruction.
 * Foreign Fanservice: Slightly over a minute into the series the presence of overseas students is stated to be one of the great things about the school. When she's introduced it's mentioned that Rias is rumoured to be Scandinavian and after the Bedmate Reveal in episode 2 Issei's mother specifically states her son's in bed with a foreign girl.
 * First-Episode Resurrection
 * First Kiss:
 * Five-Man Band: There are quite a few examples in this series.
 * Occult Research Club:
 * The Hero: Issei
 * The Lancer: Kiba
 * The Big Girls: Akeno, Koneko, and Xenovia
 * The Smart Girl: Rias
 * The Chicks: Asia and Gasper
 * The Mentor: Azazel
 * Sixth Rangers: Irina, Rossweiss, and Ravel
 * Vali's Group
 * The Hero: Vali
 * The Lancer: Bikou
 * The Big Girl: Kuroka
 * The Smart Guy: Arthur
 * The Chick: Le Fay
 * Team Pet: Fenrir and Gogmagog
 * Freeze-Frame Bonus: you can see Issei's penis in the beginning of episode 2 when his mother closes the door. Funnily enough, this gets removed in the blu-ray version.
 * "Friend or Idol?" Decision: During a break from their sparring, Azazel asks Kiba between Issei and Rias, who would he save. Kiba then flat out tells him that he'll save Rias because without her, everything is lost.
 * Gainaxing
 * Gondor Calls for Aid:
 * Good Old Fisticuffs: What pretty much happened with Issei VS Sairaorg.
 * Guilty Pleasure: In universe example, Issei has gone...somewhat far with some of the girls, to the point it's just short of sex.
 * Handshake Substitute: Issei and Kiba do the fistbump variation just before they go to their separate positions in their first Rating Game.
 * Hard Work Hardly Works: Subverted Hard. Issei is mentioned constantly to be talentless and no good at anything at all. He goes through Training From Hell constantly to improve himself and in the end it worked. He turned out to be the strongest out of the Occult Club which consisted of some of the most talented individuals and some of them even had special lineages such as the the sister of the current Maou and the daughter of a leader in the Fallen Angel faction. He even eventually muched up to Vali who had the lineage of the original Maou to back himself up. The author himself mentioned that this is a series where hard work pays off and it shows. Azazel even thinks of Issei as a sponge who can absorb anything. Same thing with Sairaorg who also subverts this trope because any devil who fights off against him and loses, they don't have what it takes to bounce back since their powers don't work on someone who's just using his body as a weapon.
 * Harem Seeker: Issei's dream upon entering high school. Didn't quite work out, what with not being able to get a girlfriend let alone the many required for a harem. Rias promises he can get one if he does a good job as a demon. Of course, the series itself is a harem romance.
 * Hearing Voices: Special sacred gears usually have something sealed within them
 * Heroic BSOD:
 * High Altitude Battle: The first fight of Volume 7 has everybody facing Loki in the air.
 * Horny Devils: The main reason Issei is cool with becoming a demon is that Rias tells him he can use it to get laid.
 * Humongous Mecha:
 * I Have Boobs - You Must Obey!: This is practically how Issei works.
 * Innocent Fanservice Girl: Asia, definitely.
 * I Can Explain: Sure you can Issei...
 * Impaled with Extreme Prejudice: Twice within the first episode. In the books, Issei's been impaled more than Jenna Jameson.
 * Issei finally gets to dish out several simultaneously
 * Instant Awesome, Just Add Dragons: There are the 3 main factions Devil, Angel, Fallen-Angels, and then there are the dragons who decided not to align with any of the 3 and are strong enough to enforce that fact.
 * I Was Just Passing Through: Vali invokes this from time to time. Sometimes however, he really does have an agenda.
 * Jaw Drop: Tanninim pulls off a funny one when
 * Jerkass:  and Matsuda and Motohama, Issei's two friends who start spreading rumors about him because Issei is so close to many beautiful women.
 * Jumped At the Call: More like sprinted towards the call but Issei definitely fits.
 * Kiai: Koneko uses them, subverted since she's not Hot-Blooded at all, rather than screaming it's a quiet "eh!" then whatever she just punched goes flying
 * Knight Templar: Quite a few with the most notable being the Old Devils Faction and the Hero Faction both absolutely convinced their in the right and willing to do anything to get what they want.
 * Lap Pillow: He gets it from 3 people, Rias in Volume 2 to unseal his powers and early on in Volume 3 from Asia. Akeno joins in on volume 4.
 * Light Is Not Good: Fallen angels can still use the power of the light, and they're in hell fighting with the devils.
 * Loads and Loads of Characters: At the start, there was only the Occult Research Club, then they added fallen angels, devils, God and his angels, dragons, exorcists, fallen exorcists, Valhalla, pretty any mythology you can think of, it's here.
 * Lovable Sex Maniac: Issei and his non-demonic pals, Matsuda and Motohama
 * Love Makes You Turn Into A Fallen Angel: Azazel explains that the first fallen angels became so was because they made out with a human being.
 * Lover Tug of War: Poor Issei sometimes.
 * Lucky Charms Title: If you want to be totally accurate, it should be "D×D".
 * Which becomes a Title Drop when you find out that
 * Marshmallow Hell: Its through hell that Issei finds his heaven.
 * Melee a Trois: There are three different powers currently in this setting: God and his angels, the fallen angels, and the devils.
 * Meido: Grafia, head maid to Rias' Brother's household
 * Ms. Fanservice: Rias and Akeno, they have Boobs of Steel, considered the 2 idols of school, and are incredibly beautiful.
 * Moment Killer: Tons in this series. If it's not Issei who says something idiotic or doesn't know what his partner is talking about, it'll either be someone else either spying on them (Irina, Xenovia) or calling them from a distance (Azazel, Odin).
 * Mood Whiplash: After discussing serious issues in volume 7, Azazel asks where Odin wants to go. He immediately declares that he wants to go to a breast club much to the consternation of the group.
 * Volume 12 starts out depressing after what happened in the previous volume.
 * Name's the Same: Sister Asia Argento
 * Oblivious to Love: Issei wants a harem, but doesn't notice the one he has.
 * Older Than They Look: Rias sometimes refers to Issei as a child in the novel, suggesting she isn't as young as she looks.. also considering Devil's can live for 10,000+ years...
 * Old School Building: Where the Occult Clubroom is located.
 * Our Angels Are Different/Our Demons Are Different: Demons and fallen angels are two separate classes of beings: demons are the original inhabitants of hell, whereas fallen angels are interlopers who settled there after getting kicked out of heaven. The two groups have been at war ever since.
 * Our Dragons Are Different: Unusual for media, but Issei's dragon is a welsh dragon. Not something you see every day.
 * Peace Conference: Happens in the fourth volume. It was successful, however there is a certain faction who doesn't want in.
 * Panty Shot
 * Pillow Fight: Rias and Akeno engage in this at the start of the fifth volume. This is also how Issei finds out that his house got renovated into a six-floor mansion.
 * Pint-Sized Powerhouse: Koneko.
 * The Power of Hate: The Maouga runs on it as it's power source.
 * The Power of Love: Issei is powered by this... but mostly he's powered by lust.
 * Powered Armor: Yes it actually does exist in the series; Issei's first dragon form is basically it.
 * Power Levels: Vali invokes this to Issei that the latter is ranked somewhere in the 4 digits and that Sirzechs won't enter the top 10.
 * The devils also have a strength tier with ultimate being the highest level and low level devil being the lowest. In a subversion however the entire Occult Club with the exception of Rias are all low level devils and they are all considered with the exception of Asia and Gasper to be high level devils if not stronger. Ironically Rias herself ends up as one of the weaker members with most of the rest of the Occult Club surpressing her.
 * Power Perversion Potential: Why else would Issei invent Dress Break during his training time.
 * Peeping Tom: The first scene in the novels involves Issei and his friends Matsuda and Motohama peeking at the girls locker room.
 * Physical God:.
 * Pretty Freeloaders: Asia is the first one who stays at Issei's home, then later on it's Rias, Akeno, Koneko, Xenovia, Irina, and Rossweisse who stay with him while Kiba and Gasper rent a house near them.
 * Radial Ass-Kicking: The Occult Research Club was going to do this, until Odin showed up.
 * Rags to Riches: Issei's home gets renovated from a normal Japanese house, into a six-floor mansion overnight.
 * Really Gets Around: Issei wants to, Raizer already has, and finally Issei's Mentor Azazel had one in the 1000s harem not women.
 * Red Baron: A lot. Generally all the high level fighters have some sort of terrifying nickname. Funnily enough Issei is called the which brings Driag no small amount of agony.
 * School Idol: Rias, Akeno, Souna, and Tsubaki in that order.
 * Sentai: Maou Sentai Satanranger!
 * Sequel Hook: The mere mention of Vanishing Dragon (Vali), made everyone jump for joy and wanted a sequel to the series.
 * Shout-Out: Numerous. Issei activates his Sacred Gear by shouting "Kamehameha!" and his first client was hoping for a female demon he could dress up as Yuki Nagato.
 * Episode 4 of the anime has a Suigintou poster.
 * Episode 7
 * Episode 7

Issei: Sprite Dragon...I choose y-!"


 * Oh and for kicks, the author is also a fan of Pokémon.
 * In episode 10, during the Ratings Game against Raiser the Rook that Koneko fights in the Gymnasium looks like Chun Li and even fights like her.
 * According to the author, he specifically denied that the three short stories in Volume 8 (Oppai Of The Tennis, Hell Teacher Azazel, and 300 Issei) had nothing to do with the series they were referencing.
 * Someday This Will Come in Handy: Back in volume 4, Sirzechs asks Issei what would happen if Issei used Gift on Rias' breasts then tells the latter not to worry about it, which obviously makes Issei think of a lot of crazy outcomes on what will happen. It mostly gets forgotten, until
 * Spank the Cutie: No, Rias doesn't get spanked; she's the one spanking you if you do anything stupid. Just ask Issei.
 * Story-Breaker Power:.
 * Superpower Lottery: Various from Sacred Gear to Sacred Gear. Kiba has the the ability to create swords with any special element he wants. Vali could Divide someone's power by two every ten seconds and Issei could double his own power by two every ten seconds. Gasper could stop time. Then there's Cao Cao who has the True Longinus that has 7 abilities which are all utterly broken such as the ability to destroy all weapons and a Attack Reflector.
 * Also besides sacred gear there are people that are born into a special lineage which gives them special power exclusive to their family. Rias's family has the power of destruction for example. Vali once again wins this lottery because he is the descendent of Lucifer thus he has great magic power that further boasts the power of his sacred gear by allowing him to feed his magic power for Juggernut Drive which allows him to be the only person that could use this ability without drawback.
 * Take That: The "Familiar Master" in Episode 7, an middle-age man who dresses and talks like Ash Ketchum/Satoshi is a not-too-kind jab at the Pokémon fandom, particularly adults who refuse to "let go."
 * Ironically, the author admits that he's a fan of Pokémon in the volume 8 afterword, and his artist told his editor to make that story.
 * Tall, Dark and Bishoujo: Rias naturally.
 * Now now don't forget Akeno.
 * Talking Is a Free Action: When Issei first uses Balance Breaker, Ddraig warns him that it's only good for 10 seconds because Issei can't handle the stress of Boosted Gear. Yet, when he's fighting and talking against Raiser, their conversation lasts for a few minutes while Ddraig is counting the number of seconds till Balance Breaker is up.
 * Teeth-Clenched Teamwork: Chaos Brigade in general is this. Ophis may be the overall leader, however the three main groups have different agendas. Vali's group is the closest one who wants to fulfill Ophis' wish to kick out Great Red from the dimension gap only because Vali wants to fight the strongest being. The Old devil faction only uses Ophis to regain Hell and wage another Forever War to prove that the devils are the strongest. The Hero Faction just wants to wipe out all the mythologies and prove that they're heroes.
 * The Alliance: The Christian faction as a whole (includes angels, fallen-angels, and devils).
 * The Chosen Many: For something to be so rare, there sure are a lot of Sacred Gear users in the setting. And that's not counting the, according to Word of God, fifteen Longinus users, one of which being Issei's Boosted Gear.
 * There Is Only One Bed: Rias sleeps naked in Issei's bed and at that point, the latter doesn't love the former.
 * Those Two Guys/Bromantic Foil: Matsuda and Motohama
 * Torpedo Tits: The exiled devil in episode 3 fires lasers from her nipples.
 * Tournament Arc: How a Rating Game works.
 * Training From Hell: Rias' training of Issei is nothing but this. Later on, he gets subjected to this by Taninim who trains him literally in hell.
 * True Companions: The Occult Club.
 * Tug Lover War: A mild example in the opening credits of Akeno VS Asia with Issei as the prize.
 * Two-Teacher School: The only teachers who are even active in this school are Azazel and Rossweisse.
 * Ultimate Showdown of Ultimate Destiny: All the different mythologies are in this series, and the only thing that's keeping them from waging war with each other is that The Alliance (devils, fallen-angels, and angels) wants to make peace with other mythologies. According to Sakra Indra, the other mythologies may be cooperating on the surface, but deep down they want to destroy the other mythologies.
 * Unprovoked Pervert Payback: Despite numerous amounts of Fan Service, this show averts it. Hell, even Ise expected that Rias was going to hit him when
 * Unwitting Pawn:
 * Valkyries: They exist in the universe, as Odin is a character within the story
 * What Does She See in Him?: It has been stated through out the story from people wondering why Rias and Asia are close to Issei . If only they knew the crap he went through for the girls.
 * Wham! Line: What Kokabiel said to the entire group which is  So much so it caused Xenovia a Heroic BSOD.
 * What Do You Mean It's Not Awesome?: Issei's Alarm clock.
 * Issei's Dress Break debut in episode 10. Complete with Ominous Latin Chanting.
 * Will They or Won't They?:
 * Winged Humanoid: Everyone that's on one of the three factions. The Angels and their Fallen former comrades have the feathery kind (normal angels have white wings while those of Fallen Angels are black), Demon wings are more bat like.
 * Would Hit a Girl: Pretty much almost every male in this series have no problems fighting against women at all.
 * Xanatos Speed Chess: Well, the Rating Game is a team battle that involves adjusting the strategies in response to the opponents actions.
 * You Are Worth Hell: Issei went through a lot of crap to rescue Asia. It's a Long Story.
 * Your Approval Fills Me with Shame: Ddraig isn't taking the nickname  everyone gave him very well due to how Issei uses his power.
 * Your Approval Fills Me with Shame: Ddraig isn't taking the nickname  everyone gave him very well due to how Issei uses his power.
