The Occult Research Club

Formed by Rias Gremory during her first year at Kuoh Academy, the Occult Research Club is the extracurricular club that our heroes 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.

In General

• All Women Are Lustful: All the girls want Issei's attention, including in more sexual manners.
• Almighty Janitor: 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. Even after Issei, Akeno, and Kiba's promotion, it's implied they are still not promoted to a level that 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.
• Arch-Enemy: As a whole, the club serves as one of the Khaos Brigade's enemies.
• Back from the Dead: Every Sacred Gear wielder in Rias' peerage had died right before she reincarnated them into a Devil. Issei, in particular, goes through this a second time.
• Badass Crew: It's basically an unspoken rule that, if you are or become part of the Occult Research Club, you either were already a badass or will become a badass, and joining the group means becoming one of the True Companions that have each other's backs.
• Badass Family: What Rias regards her club as, with her as the "mother" that holds it together.
• Battle Harem: All the members of the Occult Research Club are strong fighters and they all love Issei. Even Issei's fellow male club members Kiba and Gasper adore him. It gets lampshaded by the author himself at one point.
• Break the Cutie: Almost all the members of Issei's harem after his "death", showing how psychologically dependent they are on him due to his help in overcoming their respective Dark and Troubled Past. Fortunately subverted after he comes back to life with some draconic backup.
• Crippling Overspecialization: One criticism Azazel throws their way in regards to Rating Games is that they have "muscles for brains"; they focus too much on straightforward power, and can easily be overcome with proper technique.
• Dark Is Not Evil: Most of them are devils. They're also the heroes of the story.
• A Day in the Limelight: A member of the club is usually the focal point depending on the volume.
  • Volume 1: Issei and Asia's introductions into the devil world.
  • Volume 2: Rias's love life.
  • Volume 3: Kiba's tragic past with the holy sword experiment.
  • Volume 4: Gasper's introduction.
  • Volume 5: Koneko training to control her senjutsu powers.
  • Volume 6: Asia's background with Diodora Astaroth
  • Volume 7: Akeno's strained relation with her father.
  • Volume 10: Issei dealing with Raynare's "curse".
  • Volume 12: Kiba protecting the Club after Issei's departure.
  • Volume 14: Ravel dealing with the Phenex-tear black market.
  • Volume 16: Gasper's life in the Romanian vampire society.
  • Volume 17: Rossweisse's study of 666.
  • Volume 18: Irina's childhood with Issei.
  • Volume 19: Xenovia's work with the student council.
  • Volume 20: Issei and his relationship with his parents.
  • Volume 22: Issei's promotion to High-Class Devil and the graduation of Rias and Akeno.
  • Volume 24: Koneko and Kuroka's relationship.
  • Volume 25: Rossweisse's love life.
• Declaration of Protection: Issei has given several to the girls, and keeping his word is a major factor in his growing harem. He also once set up a code of ethics with the other two male members of Rias' peerage, which mostly revolves around protecting the girls. Kiba once gave one to Issei himself for helping him overcome his Roaring Rampage of Revenge, but Issei is too creeped out by the fact that he's giving it to a fellow male to take it seriously.
• Dislikes the New Guy: Rias and Akeno disapprove of Azazel initially entering their territory for different reasons. However, they eventually reconsider their opinions later on.
  • Rias initially dislikes Azazel making advances towards Issei, who was understandably murdered by his accomplice Raynare.
  • For Akeno, it's because of her initial resentment of Fallen Angels (including herself) since Shuri was killed for her relationship with Baraqiel.
• Dysfunction Junction: Almost every single member of the club has or had issues that needed resolving.
• End of an Age: By the end of the fourth story arc, Rias and Akeno have graduated from Kuoh Academy and Xenovia becomes the Student Council President.
• Ensemble Cast: As the series progresses and more members join the club, the main cast continues to grow, eventually reaching 16 members. Add on Vali and Kuroka from the Vali Team and Sona and Saji from the Student Council, and the cast reaches 20 characters. With so many characters, the group usually has a Rotating Protagonist share the spotlight with Issei in each arc, whereas the other characters take a backseat. The best example would be the Kyoto Arc, where Kunou has the most focus alongside Issei, while Kiba, Asia, Irina, Xenovia, Rossweisse, Azazel, and Saji get secondary focus. At the same time, Rias, Akeno, Koneko, and Gasper remain in Kuoh and are as such Out of Focus, while Vali, Kuroka, and Sona are completely absent.
• Gender Bender: In one Volume 13 short story, the group (minus Issei) underwent a gender change via Azazel's gender-swapping raygun.
• Good Is Not Soft: The Occult Research Club is not against using deadly force against the various mooks or Big Bads they encounter and/or indirectly causing them to die. Only Issei had reservations about killing antagonists at first.
• Involuntary Group Split:
  • Zigzagged. After Issei's promotion into a High-Class Devil in Volume 22, Rias trades Asia, Xenovia and Rossweisse into his peerage and Ravel is traded into his peerage by Lady Phenex. Due to Issei being Rias's pawn and Ravel being a member of the Occult Research Club, they haven't truly split though.
  • In Volume 19, Xenovia has to leave the Occult Research Club due to her becoming the new Student Council President. In Volume 18, Rias names Asia and Kiba the new president and vice-president due to her and Akeno's upcoming graduation from Kuoh's high school division, officially doing so during Volume 22.
• Lady and Knight:
  • Rias is the benevolent and caring Bright Lady, and most of her peerage are her White Knights, who fight on her behalf in Rating Games and assist her in other endeavors. Due to the chess motifs of the Series, she has literal chivalric-gentleman sword-swinging knights like Kiba and more figurative knights like Koneko (who is more like a castle). Then there's Issei, who is her straight-up champion, but he's technically her foot-soldier.
  • Asia is like a sub-Lady, a nun so innocent and caring that Issei and the others protect her like knights.
• Long Hair Is Feminine: Of the core group Rias, Akeno and Asia have long hair and are very feminine (in different mode) while Koneko and Xenovia are more Tomboy.
• Moment Killer: 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 Can't Have Sex, Ever clause in writing this story.
• Non-Indicative Name: They don't do any occult research. The name was simply chosen as a cover-up for the fact the club was initially comprised of Rias' peerage.
• The Pirates Who Don't Do Anything: They don't actually do any occult research, the club is merely a front.
• Pyrrhic Victory: 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.
• Ragtag Bunch of Misfits: While they claim to be a club, it's more accurate to call them a family comprised of people that don't really belong anywhere else. Their leader is a devil princess, and among their members include the sole survivors of a lethal experiment by the church, a Nephilim priestess, two former agents of the church, one of the Angels of Micheal, a nekomata, a crossdressing dhampir, an eccentric fallen angel, a thrifty valkyrie, an ojou phoenix, the descendant of Morgan le Fey, a prankster grim reaper, a kitsune princess, the Dragon God of Infinity, and a very perverted Red Dragon Emperor. Despite these different backgrounds and any initial animosity, they all care for one another and won't hesitate to show it.
• Rescue Romance: A lot of the girls fall in love with Issei due to him saving them when they needed help. Examples include Asia, Rias, Koneko and Rossweisse.
• Run or Die: The girls are told by Ddraig to run away from Issei's wrath against Shalba or they'll die with him.
• Single-Target Sexuality: Most of 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 the church, Koneko dislikes perverted things. However, they enjoy Issei and all love him to the point they can't live without him. The only exception amidst the girls is Tosca, who doesn't know Issei that well and is closer to her Childhood Friend Kiba.
• Single Woman Seeks Good Man: The girls keep falling in love with Issei despite his perverted nature because he is a good guy at heart who will literally go through hell to protect them.
• Spanner in the Works: Had Rias not provide Issei Hyoudou's Emergency Transformation after Raynare's killing, then Issei wouldn't have had to rescue Asia and battled Riser to stop his engagement with Rias. Had none of those recruitments after Issei happened, they wouldn't have allied with the Three Factions. Not to mention Xenovia never would've realized that God Is Dead and joined the club, or Irina would never have reunited with Issei, or Akeno wouldn't have reconciled with Baraqiel, and so forth.
• Switching P.O.V.: 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 something is going on with Issei), Azazel (when there's a discussion with the leaders involved), Asia for a brief period, and Irina in one of the short stories.
• Took a Level in Badass: Throughout the series, as time goes on everyone in the Occult Research Club starts actively grinding levels in badass, especially Issei and Kiba.
• True Companions: Despite all the girls wanting to be with Issei, they still trust and help each other no matter what happens. Mocking any of them will set all of their Berserk Buttons off at once.
• Undying Loyalty: The club members have a strong sense of loyalty for their group. Even from beyond the grave.
• Unskilled, but Strong: 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 Sona's group, which almost spelled defeat for them.
• Unwitting Pawn: They become one for Vali in Volume 7 seeing as the latter wanted Fenrir on his side, thereby fighting alongside them.
• What Does She See in Him?: With a bunch of really hot babes being head-over-heels for a Lovable Sex Maniac that most girls would typically avoid, this was inevitable. Though, subverted as all pervertedness aside, Issei cares deeply for all the girls in his life.
• World of Buxom: In the future, all of the girls (possibly including Ophis) have a Buxom Beauty Standard figure, to the point that their children thought at first that women should have large chests. Yes, even Koneko, Le Fay and Asia.

Leadership

Rias Gremory

President Rias Gremory

Role: King
Species: Pure Devil
Voiced by: Yōko Hikasa (Japanese), Jamie Marchi (English)^{Foreign VAs}Carmen Katt (German)

My name is Rias Gremory. I am a Devil. And I am your Master. Nice to meet you, Hyoudou Issei-kun. Can I call you Ise?

Rias Gremory is the president of the Occult Research Club and the head of the House of Gremory. She's also the daughter of Zeoticus and Venelana Gremory, the younger sister of Sirzechs Lucifer, and aunt of Millicas Gremory. She is a top-ranked devil at Kuoh Academy who catches the eye of Issei Hyoudou. Later, he summons her with his dying words. Taking pity on the boy, and also because she's interested in his Sacred Gear, she revives him with eight Pawn pieces. After that, an interesting relationship blossoms between the two.

---

• Absurd Phobia: According to a short story, Rias has a fear of camels, because she got hurt by wild camels after she sneaked out to go to the farm when she was still young. One would have to be knowledgeable about the Ars Goetia to understand exactly why this is so funny. ^note Gremory is a demon lord of the Ars Goetia who is depicted as a beautiful maiden riding a camel.
• Action Girlfriend: Rias is a devil who appears when Issei summons her in his final moments. She then resurrects him as a devil and becomes his master, main love interest and eventual girlfriend.
• Adaptation Dye-Job: She has blue eyes in the novels, but bluish-green eyes in the first three seasons of the anime.
• Ambadassador: She participates in missions that she often solves diplomatically. But when things go south, she's not afraid to go toe-to-toe with her enemies, like what happened in Katerea's invasion of Kuoh Academy.
• And I Must Scream: Thanks to Loki's corruption in BorN, she's unable to fight his control until Issei snaps her out of it and her memory gets erased.
• Arranged Marriage: Rias was placed into an engagement with Riser Phenex in an attempt to unite their families and to preserve the bloodline of Pure-Blooded Devils.
• Babies Ever After: In the future she has a son with Issei, named Ex.
• Badass in Distress:
  • That is, if you can call the engagement party with Riser being a distress moment.
  • Since her body gets corrupted by Loki's curse in BorN, she is trapped within herself.
• Bathing Beauty: She has many Shower Scenes.
• Battle Couple: She eventually gets together with Issei. Becomes more so when her breasts act as a battery for Issei.
• Bedmate Reveal: In Volume 1, Issei wakes up thinking the events of the previous night were just a dream. Then he notices he's naked. And that Rias is curled up under the blankets next to him equally naked before she awakens and is completely nonchalant about the situation. Hilarity Ensues when Issei's mother enters his room.
• Benevolent Boss: She loves her subordinates so much she treats them as a family rather than employees. Rias is utterly heartbroken when Asia is sent to the Dimensional Gap and Issei is once again killed by Shalba.
• Berserk Button: Calling Rias "Switch Princess" to her face tends to tick her off, especially if the one doing it is Bikou.
• Betty and Veronica:
  • When she moved to the Hyoudou residence, Rias and Asia are the girls treated as Issei's primary love interests since the harem was just starting to form. Rias is the Veronica; the beautiful and sexy devil of noble heritage who is way out of Issei's league from his perspective.
  • Rias herself plays the Betty compared to her best friend Akeno's Veronica. While both girls are highly beautiful and atractive, each of them have a different approach where it comes to expressing their love for Issei. Rias is shown to be more innocent and sometimes shy in progressing her relationship with Issei, while Akeno is more seductive and sultry, being very eager to quickly advance her relationship with him, which including sleeping with him, much to Rias' jealousy.
• Beware the Nice Ones: She is one of the nicest and personable schoolgirls you will ever meet. Nevertheless, if you push her far enough (such as insulting her servants, especially Issei), she will be prepared to vaporize you into dust.
• Big Good: She serves as one for the Occult Research Club as president way back in Volume 1.
• Birds of a Feather: Downplayed, but part of the reason why Issei and Rias get along despite their differences is them being able to relate to being kind and protective souls, who find value in even small gestures of affection and having to deal with awkward parents. (Morbidly enough they’re the ONLY ones in the club with two living parents, at all).
• Blood Knight: A subdued example. Rias has no love for life-and-death violence at all, but she does greatly enjoy Ratings Games as the good, clean combat sport they were intended to be. According to Ichiei Ishibumi, much as Issei's goal of ending the war is to focus on having a harem, her goal is to clean out the corruption so she can fight safely once again.
• Brainwashed and Crazy: In episode 10 of BorN, Loki corrupts her with his curse. Fortunately for Rias, her memory of that event gets erased after Issei snaps her out of it and defeats Loki's clone two episodes later.
• Breast Expansion: An inverted example; restoring Issei with her breasts after Gift being used on them causes them to shrink. Fortunately (for Issei) they grow back after she rests.
• Buxom Beauty Standard: She has a pretty buxom figure, which is the source of a lot of Male Gaze shots and stares from Issei. Asia also feels insecure around her because she can't measure up.
• Calling the Old Man Out: After finding out the dark secret before she became in charge of Kuoh Town, she calls out Zekram Bael, her maternal ancestor.
• Can't Catch Up:
  • Unlike the rest of the club, she doesn't gain any new ability; thus, she did not get any stronger than where she was initially, to the point that she thought of herself as The Load during her and Issei's fight against Sairaorg and his Pawn.
  • This is eventually rectified as she does learn or gain various new abilities thanks to absorbing and adapting Issei's aura, such as the finishing move Extinguished Star and her own version of the boosted gear's armor.
• The Chessmaster: As King of her peerage, she can determine where her pieces will go in Rating Games and battles.
• Childish Pillow Fight: She gets into one with Akeno as the two quarrels over Issei, after Akeno moves into Issei's house.
• Clingy Jealous Girl: After falling in love with Issei, Rias tends to get very jealous whenever girls get close to him and said that Issei belongs to her only. She's generally quite playful and teasing when confronting the relatively more aggressive Asia, only to become aggressive herself when confronting the more teasing Akeno. It's subverted after Issei confesses to her and they start dating; Rias starts to accept Issei's dream of having a harem and doesn't get as easily jealous as before.
• Club President: She is the president of the Occult Research Club until Asia replaces her by the end of Volume 19.
• Cool Big Sis: Rias is lovingly kind or sternly mature as the situation calls for it.
• Crazy Enough to Work: Her magical breasts work because of this trope.
• Crutch Character: At the start, she's the strongest member of the club. As time goes on, she devolves into the middle tier (for a while that is). Technically she didn't get any weaker; the others just got stronger more quickly than she did (again, only for a while).
• Cuddle Bug: Fittingly to her kind and motherly nature, Rias is always quite eager to hug and cuddle her servants in times of struggle (whether to comfort them or to express how glad she is that they're alive and well) having zero problems on whether the one on the receiving end is male or female. She does seem to have a preference towards hugging Issei though.
• Cute Little Fangs: Some of the light novel artwork portrays her with these.
• Daddy's Girl: She loves her father Zeoticus very much. As does he, to the point where he and Sirzechs had nosebleeds by looking at how Rias acted as a child.
• Deliberately Distressed Damsel: She didn't really want to play as the Damsel in Distress to lure out the remaining Issei clones. Then she gets into it, believing Azazel's suggestion. Sure enough, the Issei clones go and try to rescue her.
• Deuteragonist: Behind Issei, who is the focal protagonist, Rias is the second main focal character of the series.
• The Dividual: With Akeno in nature. From narrative perspective is clear that they are intended to work as an indivisible combo for all kind of actions. Yes, even (or maybe especially) that ones.
• Does Not Like Men: A Downplayed example. She gets along fine with males, right up until they show any romantic interest in her whatsoever, at which point she promptly rejects them. This is because, as heir apparent to the house of Gremory, the only men who've ever been interested in her were only interested in her house and title, not the woman; by the time she grew up into a Ms. Fanservice, she'd been soured on the idea of romance altogether. Issei, being the Chivalrous Pervert he is, helps her open her heart to him and him alone.
• Don't Call Me "Sir": Rias starts taking an issue with Issei continuing to call her "President" instead of her actual name since it makes clear he's trying to create a distance with her that he doesn't have with the other girls.
• Do Not Taunt Cthulhu: She does not take kindly to anyone mocking her servants and is willing to blast them to kingdom come.
• Drill Sergeant Nasty: She is tough on Issei when he beings training with her.
• Embarrassing Nickname: Later on, she becomes known as "Switch Princess", much to her embarrassment, and blames Bikou for it; it's become a major Berserk Button for her since. She is later called the "Crimson Bust Princess" by Azazel in Volume 11.
• Everyone Can See It: After falling in love with Issei, everyone has noticed her romantic affection for him, except ironically, Issei himself initially. Her father even asked Issei to call him father-in-law when the Gremory peerage visited the Gremory territory.
• Exact Words: He refers to Issei as a pawn, and although at the beginning that may mean that he is completely sacrificial, what Rias was actually referring to is that Issei fulfills the role of all 8 pawns at once, so in reality he is very useful.
• Face Palm: She often does this all the time, usually out of frustration.
• Fiery Redhead: Subverted; normally, she's overall rather level-headed and seldom raises her voice even when she's serious. She does, however, bring this out when it comes to Issei, but even then she does grow out of it to an extent later in the series.
• First Kiss: She shares her first kiss with Issei by the end of Volume 2.
• Flight of Romance: Issei and Rias shared an intimate moment on top of a Gryphon when returning to the human world, as Rias gives Issei her first kiss after hearing his proclamation to always rescue her.
• Go-Go Enslavement: During an OVA an Egyptian prince possessing Issei makes her dance for him in a very skimpy bikini outfit. Naturally, he and Issei both enjoyed it.
• Heroic Sacrifice: This trope is parodied in Volume 11, when her "Oppai Beam" replenishes Issei's aura, but leads to her breasts shrinking afterward. Issei is devastated, but Rias assures him that they'll return to normal size once she gets some rest, leading to the two tearfully and hammily expressing their love for each other.
• Heterosexual Life-Partners: She refers to Akeno as her best friend. Akeno is her Queen and the first person she added to her peerage.
• Hidden Depths: Along with Akeno, Rias actually has a driving license so she can have driving dates with Issei.
• Hot Teacher: She cosplays as this in the third season's first Blu-Ray special in an attempt to outdo Akeno in a seduction contest for Issei.
• Idiot Hair: While definitely not an idiot, Rias has a single hair strand sticking out from the top of her head.
• If It's You, It's Okay: Because Issei appreciates her body, she becomes romantically interested in him.
• "I Know You're in There Somewhere" Fight: Towards the end of BorN, Issei is forced to fight Rias because of Loki creating multiple timelines.
• Image Song: Crimson No Binetsu
• Intimate Healing: She heals Issei's wounds from Dohnaseek's by cuddling naked with him in bed.
• Lap Pillow: She gives one to Issei when she unlocks a portion of his Pawn pieces' power. After falling in love with him, she is shown to do it a lot.
• Large and in Charge: Rias is a 172 cm/5'8'' girl who's the Occult Research Club's president and one of the tallest members of the club.
• Laser-Guided Amnesia: At the end of BorN, the memories of her and Issei's battle with Loki's clone of Issei are erased when they return to our world.
• Leg Focus: As the primary Ms. Fanservice of the series, alongside her ample breasts getting Male Gaze she has plenty of scenes dedicated to highlighting her legs, helped by both many of her outfits fully exposing them and the fact she Sleeps in the Nude.
• Leitmotif: Her early appearances in the anime are accompanied with Shinsou no, Ojou-sama Desu - a calm orchestral piece befitting of her elegant disposition and warm, motherly personality.
• Let's Get Dangerous!: After Issei 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.
• Lineage Comes from the Father: Subverted. While she has red hair and blue eyes like her ancestors from her father's side, her Power of Destruction abilities and strict demeanor come from her mother's side.
• Made of Temptation: She 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. This comes to a head when EX reveals that Rias indeed becomes a very successful businesswoman, managing company holdings and franchises that her husband Issei and the family own.
• Magnetic Hero: 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.
• Marry for Love: Rias is shown to have a strong desire to marry out of love rather then merely being forced into a politically motivated marriage. She rejected her engagement with Riser Phenex since it was arranged without her concent, as the engagement was annauled due to Issei's actions. Rias was shown to be very happy when Issei proposed to her after she graduated from Kuoh High.
• Matchmaker Crush: She initially tries to pair Issei and Asia together, until Rias falls in love with Issei herself. However, due to the harem aspect of the series, it is shown that while the two girls do compete for his attention and affection, they remain on good terms, with Rias even praising Asia when she made the first move to seduce Issei.
• Mistress and Servant Boy: She is the mistress to Issei's servant.
• A Mother to Her Men: She really loves her servants; breaking their hearts and making them cry is a one-way ticket to the afterlife. Ddraig states that the Gremory family is known for being extremely affectionate toward their servants.
• Motivational Kiss: Gives one to Issei before his Mid-class Devil exam, with the belief that he will pass.
• Ms. Fanservice: She has the second largest bust in the series and not afraid to show it off. In general, she is the character that appears naked more often (since the first episode).
• Naked Apron: She wears one after seeing Asia wear one to seduce Issei, commending Asia for making the first move in seducing Issei.
• Naked First Impression: She introduces herself to Issei after the two wake up from sleeping on his bed.
• Names to Run Away from Really Fast: As the Crimson-Haired Ruin Princess, mentioning Rias by name and her Power of Destruction brings fear to her enemies. For that matter, her surname, Gremory, is shared by one of the seventy-two demons of the Goetia.
• Nice Girl: Despite her strict nature during missions and training, Rias is very kind and caring toward her Peerage than most other masters. That is if you don't push her buttons.
• Official Couple: In Volume 10, Issei finally confesses to her and she officially becomes his girlfriend. Issei still wishes for a harem and now that she's secure about how he feels about her, Rias will let him have it as long as she's always number one. He proposes to her in Volume 22 and she accepts, making her the first official fiancee in an ever-growing list of them.
• Ojou: The heiress of the Gremory Clan.
• Onee-sama: Along with Akeno, she's referred to as one of the "Two Great Ladies of Kuoh Academy".
• Out-Gambitted: She was overpowered by Sona during their Rating Game in Volume 5.
• Passing the Torch: Upon her graduation, Rias assigns Asia to take her place as the club's president.
• Peerless Love Interest: Issei and Rias are in love with each other, but since she's a beautiful top-ranked devil, he one-sidedly decided she was out of his league and decided to be content with fighting as her loyal pawn. This becomes a problem as the series goes on since Rias wants to take their mutual feelings to the next level, but Issei is still treating their relationship as master-servant. This reaches its peak in Volume 10 when Issei claims Rias is his master and nothing else before the rest of the Club spells out the problem for Issei.
• Person of Mass Destruction: She has the "Power of Destruction", a type of demonic energy that allows her to release energies that can disintegrate matter, both living and inanimate, with relative ease. She is further able to control the shape and power of the technique such as creating multiple softball-sized bullets to lessen the destructive force yet increase the range of her attack.
• Playing Card Motifs: In the ending theme of the anime's first season, there's a playing card theme, and Rias is shown as the King.
• Pre-Mortem One-Liner: She says "You've toyed with my servant's emotions for the last time. Be gone!" to Raynare, right before blowing her to smithereens.
• Property of Love: As Issei's master, Rias calls him her possession and says that he belongs to her only. This was taken up a notch later on as Rias' feelings for him grow and she doesn't want any girls close to him. This eventually changes in volume 10 when they become an Official Couple, even letting him have a date with others and a harem.
• Proud Beauty: Rias enjoys Issei ogling her.
• Purely Aesthetic Glasses: Sometimes wears a pair of glasses, even though she has good vision.
• Rank Scales with Asskicking: As the Heir Apparent to the great devil House Gremory and the President of the Occult Research Club, she can kick major ass when she needs to.
• Reasonable Authority Figure: Being the president of the Occult Research Club, Rias is supremely competent at her position, views her servants as a family and is willing to help fight enemies on their behalf.
• Rebellious Princess: She's Heir Apparent to the great devil House Gremory, and little sister of one of the four Satans. Kings are supposed to hang back and command their pieces. Rias prefers to mix it in — and it's not a good thing, because a team loses if their King goes down. Both she and Sairaorg are called out on this.
• Red Baron: She is known as the "Crimson-Haired Ruin Princess".
• Redheads Are Ravishing: Rias is a gorgeous and buxom Ms. Fanservice with long crimson hair. Issei, upon first seeing Rias at school, remarked to himself just how beautiful her deep crimson hair is.
• Red Is Heroic: She is one of the main heroes and has distinctive crimson hair.
• Red Oni, Blue Oni: She is the Red Oni to Akeno and Sona's Blue Oni; Akeno and Sona are the more logical and cool-headed ones while Rias has a bit more of a passionate personality.
• Risking the King: Being a powerful devil with destruction magic is a double-edged sword when it puts the leader in harm's way. Happens literally in rating games, where a manpower shortage and her reluctance to let her peerage suffer for her sake lead her to get involved quite quickly. Best shown during the first Rating Game of the series, where her strategy is a glorified diversion so she can take on the enemy king directly.
• Royal Blood: As the second-born child of the Gremory clan, she became its heiress when her brother Sirzechs became a member of the Four Great Satans.
• School Idol: Rias is declared as the beauty of Kuoh Academy.
• Second Love: Issei's first crush ended with her killing him, after which Rias revived him. While Rias is not Issei's First Love, she is his true love and eventually becomes his girlfriend.
• Sexy Mentor: She teaches Issei about how the Occult Research Club works in battles. She's also his main love interest and often shows off her sexy naked body to him.
• Shameless Fanservice Girl: She's willing to be naked in front of her servants, especially towards Issei.
• She Is the King: Using Chess Motifs, Rias is considered a King because she's the most important person in the Rating Game.
• Shipper on Deck:
  • She initially ships Issei and Asia, as she notices Asia's love and affection for Issei while Issei is clueless. This mostly stops after Rias falls in love with Issei herself, but it is shown that Asia is initially the only girl she is comfortable having around Issei.
  • Ships Tsubaki and Kiba, due to thinking of Tsubaki as a good match for Kiba.
• Shout-Out Theme Naming: Ichiei Ishibumi says that her given name comes from... Garchomp's Japanese name (Gaburias). The connection between a female Devil and a draconic Landshark is up to interpretation.
• Sickeningly Sweethearts: By the time of Volume 11, she and Issei have fallen in love to the point that they forget people are watching them.
• Sleeps in the Nude: Rias likes to sleep in the nude with Issei in the same bed.
• Squishy Wizard: She's got awesome magical attack power, but she's terrible at taking hits.
• Statuesque Stunner: She stands at 172 cm/5'8'' tall, is considered attractive by everyone else including her lover Issei, and is also the club's resident Ms. Fanservice.
• Stock Light-Novel Calamity Princess: The Trope Codifier. Heir to the Gremory devil clan and younger sister to one of the Four Great Satans, Rias is both beautiful and powerful, with striking long red hair that sometimes seems to glow in the light. With her sharp mind, and the Gremory bloodline's "Power of Destruction", she's earned the title of "Crimson-Haired Ruin Princess".^note Apparently inherited from her mother, who was known as the "Flaxen-Haired Ruin Princess". She enters a Magically-Binding Contract with The Hero Issei, becomes his girlfriend, and proceeds to be Ms. Fanservice, fighting alongside him as a team in a story that frequently features "Rating Games" against teams of other devils.
• Strong Family Resemblance: She greatly resembles her mother Venelana in her later years but with her father Zeoticus's hair and eye color.
• Team Mom: Seriously, she is more of a mother to her servants than a "master" proper.
• Tears of Joy: In Volume 10, she breaks into a crying fit of happiness after Issei confesses his love to her in private.
• Top Wife: Issei is open about his desire of having a harem, but Rias is generally acknowledged to be the one to hold the title of his "legal wife" and immutable favorite. This doesn't stop the other girls from trying to usurp the position.
• Torpedo Tits: Her "Oppai Beam", the ability to project a red light from her breasts, which recharges Issei's energy. Each use of this power causes her breasts to temporarily shrink in size, which makes Issei cry even though it's sometimes necessary. Her breast size will restore itself after a few days of rest.
• Training from Hell: She makes Issei undergo one of these, by forcing him to run as fast as she can and stretching his body to the limit.
• Tranquil Fury: Before Issei gives a Curb-Stomp Battle to Diodora in volume 6.
  Issei: May I?!?
  Rias: Go ahead.
• Unrealistic Black Hole: Her Extinguished Star technique, named after the origin of black holes as the result of a star with significant mass burning out. It creates a Sphere of Destruction that sucks in and thoroughly disintegrates even tough-scaled Evil Dragons.
• Violently Protective Girlfriend: Harm Issei and Rias will vaporize you, as Raynare and her mooks found out the hard way.
• Vocal Evolution: During the anime's first three seasons, Yōko Hikasa voices Rias with a husky, sensuous mature, and womanly voice. By the time of Hero, it suddenly softens to a sweeter, gentler, and "traditionally" girly one.
• Wife Husbandry: Gender-Inverted and Played With. Rias has stated that she intends to raise her own husband and model him as her ideal man. It is shown that some of the training that Issei goes through is for the sake of serving as Rias' future husband.

Akeno Himejima

Vice-President Akeno Himejima

Role: Queen
Species: Nephilim (Human-Fallen Angel) / Reincarnated Devil
Voiced by: Shizuka Itō (Japanese), Teri Rogers (English, 2013-14), Bryn Apprill (English, 2015-present)^{Foreign VAs}Ute Noack (German)

"You look so hot when you're being pleasured, I'm dying to know what you look like writhing in pain~"

Akeno Himejima is Rias's confidante, subordinate and fellow member of the Occult Research Club. Her late mother, Shuri Himejima, was a Shinto priest and her father, Baraqiel, is a Fallen Angel. After her mother's death at the hands of Akeno's relatives, she went into exile. When Rias discovers Akeno, she transforms the latter into a devil and she eventually becomes the vice-president of the ORC.

---

• The Ace: She is quite skilled and adaptable in combat, to the point that some of the other characters are fearful of facing her due to her abilities as well as her queen ranking.
• Affectionate Nickname: She calls Issei "darling" after his match against Baraqiel.
• The Aloner: She became a hermit after Shuri was killed in her backstory.
• Authority Equals Asskicking: As Vice-President of the Occult Research Club, she can take down enemies singlehandedly.
• Babies Ever After: In the future she has a son with Issei, named Kurenai. Interestingly enough, she is also the first haremette to have a baby.
• Bathtub Bonding: She walks in on Issei bathing and joins him in Volume 23. She wishes to be a good wife and washes every part of his body. They soon become intimate until they were interrupted by Ophis, Lilith, and Kunou.
• Bedmate Reveal: At the beginning of Volume 5, Akeno enters Issei's bedroom and joins his friends after she moves into his residence.
• Beneath the Mask: She's introduced as the friendly and cheerful - if a bit sadistic - vice-president of the Occult Research Club and Rias's Number Two. In actuality, she turns out to be a sad young girl who resents her father Baraqiel for not being able to save her mother from being murdered.
• Betty and Veronica: She acts as the Veronica to Rias's Betty, especially in their wildly different approaches in terms of getting closer to Issei; Rias is more demure and innocent about furthering her relationship, while Akeno has no such qualms and is far more forward.
• Big-Breast Pride: One of, if not, the bustiest in Iseei's harem which she is quick to remind the still buxom Rias of in their friendly rivalry for his affections.
• Blood Knight: She enjoys combat a little too much for comfort.
• Boomerang Bigot: Akeno is a Nephilim who originally despised other fallen angels. The reason for this hate was that her mother was killed by her relatives for Akeno being part fallen angel and the fact that her father failed to save her mother. Due to witnessing the actions of other evil fallen angels such as Raynare and Kokabiel, increased her hate towards them as well as her self-loathing. due to this, she sympathizes with those who have suffered at the hands of fallen angels such as Issei and Asia. She falls in love with Issei due to him telling her he likes her despite being a fallen angel. After reconciling with her father, she lets go of her hatred and embraces her fallen angel heritage to get stronger.
• Born of Heaven and Hell: She's part human/fallen angel and reincarnated devil. While normally she sprouts devil wings, she can actually sprout a fallen angel wing on one side.
• Broken Hero: A female example. She's in quite a bad position, as she makes it clear to Issei that because Baraqiel wasn't around when her family murdered Shuri, she went into exile and is unwilling to forgive him. She's noted to be one of the more emotionally fragile members of the Club, especially regarding Issei, whose supposed death left her borderline catatonic.
• Bunny Girl: She dresses up as one to attract Issei's clones. Naturally, they all fall for it, hook, line and sinker.
• Buxom Beauty Standard: She has an ample bust, and while this is a trait that's common for female Fallen-Angels, Azazel notes that her breasts are impressive even for Fallen-Angel standards.
• Birds of a Feather: Downplayed, but part of the reason why Issei and Akenoget along despite their differences is them being able to relate to being obscenely horny Japanese teenagers with more inner pain than their outer personas would let out at first.
• Calling the Old Man Out: This is one of the reasons she joined Rias's group: she calls Baraqiel out for not being able to save Shuri and is initially unwilling to forgive him.
• Casual Kink: Yes, she likes BDSM. One of the bonus artworks for the Blu-Ray releases even shows her tied up in a traditional shibari style.
• Catchphrase: She often quips, "Oh my...^note Ara ara...", before giving out a cheerful chuckle.
• Cat Fight: She does this with Rias a lot once she falls for Issei too.
• Child of Forbidden Love: Akeno was born to Baraqiel, a Fallen Angel Cadre, and Shuri Himejima, a miko of the Himejima family. Due to Himejima's oath of service to the Shinto Gods, it was forbidden to mate with other species especially those that were considered heathens. Akeno's Nephilim heritage was the reason why the Himejima clan exiled and later killed her mother.
• Childish Pillow Fight: Gets into one with Rias as the two quarrel over Issei, after she moves into Issei's house.
• Combat Sadomasochist: She takes a great deal of pleasure from inflicting pain on others, and her primary method of doing this is in her combat support role as Rias Gremory's Queen.
• Cool Big Sis: To the Occult Research Group and by extension, to the Academy.
• Cosplay: Akeno has an interest in cosplay, often dressing up in revealing outfits to seduce Issei.
• Cynicism Catalyst: Just like what happened with Issei, Shuri's death at the hands of her relatives led to her becoming disillusioned with the Fallen Angels, including Azazel. She eventually reconciles with them around the time of Loki's defeat.
• Daddy's Girl: When she was younger, she would fawn over Baraqiel and was very clingy to him. This stopped after Shuri's death caused Akeno to hit the Despair Event Horizon. After reconciling, Akeno is shown to get along with her father though she likes to tease him such as pretending to still be angry at him or telling him that she would cheer for Issei instead of him during the Rating Game between the two.
• Dark and Troubled Past: Oh ye gods. Her's is possibly the worst of the bunch. Her priestess mother, Shuri Himejima, was killed by her own relatives from the Himejima Clan when she was a child. Akeno crossed the Despair Event Horizon and called out Baraqiel, her Fallen Angel father, for not being able to protect Shuri. After Shuri's death, she stayed with her mother's relative before being removed due to her Fallen Angel blood. Without food or money and finding herself unable to go home again, Akeno went into exile and journeyed throughout Japan using her skills to purify evil spirits that she learned from her mother to survive, doing so for a year-and-a-half. When she stumbled into a certain town, Akeno indirectly saved a human that was contracted with a Devil from the Gremory Clan. Fearing that the Devil would kill her due to her Fallen Angel heritage, Akeno decided to hide from them. Later, while trying to leave the town, Akeno was suddenly attacked again by her relatives who came to kill her. Before her great-uncle could deliver the coup de grâce, Rias and her father's Bishop, Heinrich Cornelius Agrippa, appeared and talked Akeno's family out of killing her. Akeno was transformed into a devil, moved into the Gremory Palace and eventually became Rias's close confidante and Number Two in the Occult Research Club.
• Despair Event Horizon: She crossed it years ago when she witnessed Shuri Himejima's murder by her own relatives. She crosses it again in volume 12 when she thought Issei died.
• Despair Speech: In volume 7, Akeno laments to Issei that Baraqiel should never have left her to fend for herself after Shuri's demise. She can't even call Baraqiel her father ever since.
• Devoted to You: Akeno is deeply in love with and devoted to Issei, with it being shown that his presence, including something happening to him or his absence, can greatly affect her mental state, such as being angry when he was defeated in a Rating Game, being sad when he had to leave for a field trp in Kyoto, or going catatonic after Issei was presumed dead. While it's shown that she is very calm with the harem situation around Issei, Akeno is noted to fall into a depression if she truly believes that Issei is taken away from her.
• Dissonant Serenity: How could she be giggling after killing someone?!
• The Dividual: With Rias in nature. From narrative perspective is clear that they are intended to work as an indivisible combo for all kind of actions. Yes, even (or maybe especially) that ones.
• Does Not Like Men: She is implied by Rias to hate the other sex (except Issei) during their Cat Fight in Volume 4. It's not hard to see why, given her Dark and Troubled Past and her strained relationship with Baraqiel. However, due to her never being hostile towards any males outside of antagonists, and initially Azazel and her father on the basis that they're Fallen Angels without any regard to their sex, this is an Informed Attribute.
• Dull Eyes of Unhappiness: Played for Drama at the start of Volume 12, following Issei's (temporary) death. Played for Laughs in the Hot Springs short story, when she walks in on Grayfia and Issei, coming to the assumption that she has a "real affair" with him, and drops on the floor with hollow eyes.
• Elemental Powers
  • Shock and Awe: She can zap enemies with her lighting.
  • Light 'em Up: Her Holy Lightning, which she inherited from her father. She initially hates using these powers until Issei convinces her otherwise.
• Erotic Dream: She tends to dream of her and Issei having sex.
• The Exile: The double blow of losing Shuri and calling out Baraqiel for failing to save her mother (which Azazel also feels directly responsible for, since Baraqiel effectively served as his second-in-command and wasn't around at the time of Shuri's death) caused her to go into exile for nearly two years, disappearing from almost everything except for purifying evil spirits. However, after healing a devil belonging to the Gremory family, Rias would soon find her.
• Eyes Always Shut: She sometimes keeps her eyes closed whenever she tries to seduce Issei.
• Fantastic Racism: Originally, Akeno had a very low opinion on Fallen Angels. Then again, considering that Shuri was murdered by her own relatives when Azazel sent Baraqiel on a mission, Akeno called out Baraqiel for not being able to save her mother, and she went into exile after that, her views are understandable.
• First Kiss: She gives hers to Issei in volume 7.
• The Gadfly: She likes teasing people in various ways. Her favorite is to tease Rias over Akeno's own closeness with Issei and that Akeno will have an affair with him behind Rias' back, much to Rias' frustration.
• Hair Antennae: A rather unique variant in which they slope backward, rather than forwards.
• Half-Human Hybrid: Her mother Shuri was a human Shinto priestess, while her father Baraqiel was a Fallen Angel.
• Hates Their Parent: Akeno despises her father Baraqiel ever since he failed to save Shuri from being murdered by the Himejima clan. However, she eventually reconciles with him once Issei learns her true feelings.
• Heartbroken Badass: The loss of her mother has sent her into a Heroic BSoD, but she crawls out over it by the time of volume 7. She goes through it again when in volume 12 when she thought Issei was killed and was very determined to get the one's responsible.
• The Hermit: After losing Shuri at the hands of her own relatives, she retreated into complete isolation for one year.
• Heroic Seductress: Rias comments that Akeno would make an excellent succubus. Noted that she only desires to sex up Issei.
• Heterosexual Life-Partners: She refers to Rias as her best friend.
• Hidden Depths: Despite being a tease-happy sadomasochist on the surface, Akeno is surprisingly innocent when it comes to having a true relationship, which stems from both her terrible past and dutiful personality.
• Hope Spot: She gives one towards the Issei clones before decimating them with her magic.
• I Am Not My Father: She tries to not make the same mistakes her father did during her childhood.
• Idol Singer: She practices singing the Oppai Dragon song to become a songstress for the show.
• If It's You, It's Okay: An odd variant; while Akeno prefers being dominant in S&M sessions, much like in her bonding/reconciliation moment with her father, Issei is the only one allowed to see her masochistic side when the time comes.
• I Hate You, Vampire Dad: She clearly hated Baraqiel for not being able to save Shuri when the latter was killed, doing so to preserve her sanity.
• Image Song: Kurokami BEGIN TALE
• Informed Attribute: Despite Rias insisting that Does Not Like Men and therefore shouldn't be fighting with her over Issei, the only non-antagonistic males she has shown overt hostility toward (initially) are Azazel and her father, which has more to do with them being Fallen Angels than their sex.
• It Runs in the Family: 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. She also inherited the Holy Lightning from her father.
• It's Personal: She wants to exact revenge against the Khaos Brigade after thinking they killed Issei.
• The Lancer: In as much as Rias is The Hero due to her status as a Deuteragonist, Akeno is this. She's always smiling, especially in combat; she takes actions Rias would, sometimes without telling her beforehand to avoid the debate that would ensue, and she's never above flirting with Issei to get a rise out of Rias, especially after they've both fallen for him.
• Lecherous Licking: She elevates this trope into an art form, sucking out Issei's excess Dragon energy as erotically as possible. She also likes to lick her lips while sadistically zapping her enemies.
• Leg Focus: As the second-most prominent Ms. Fanservice after Rias, she too has numerous scenes dedicated to highlighting her amply curvy legs, and being The Tease means she often poses to display them.
• Lineage Comes from the Father: She inherited her Shock and Awe powers and Fallen Angel wings from Baraqiel.
• Long-Lost Relative: She's related to SLASHDØG protagonist Tobio Ikuse by blood since his grandmother was a Himejima, making him her distant cousin.
• Marry Them All: Zigzagged in her case. Baraqiel criticizes Issei during their Rating Game match in Volume 22 for choosing Rias over Akeno, prompting Issei to declare that he will make all of the women who love him happy and shout out that he loves Akeno to the whole stadium (mirroring how he declares his love for Rias in Volume 10). Whether or not this counts as a proposal is debatable, as he only singles Akeno out because the whole thing was brought up by her father, but Akeno herself later says that marriage isn't necessary (because she thinks affairs are sexy, and you can't have much of an affair with your own husband...)
• Matchmaker Crush: Akeno is shown to support Issei's relationship with Rias, though it doesn't stop her from seducing him herself or trying to have sex with him.
• Miko: Dresses as one when it's time to get really serious. She inherited it from her mother.
• Missing Mom: Akeno's mother, Shuri, died during her childhood.
• The Mistress: What she wants to be for Issei. She actively pursues this. Rias is very aware of her "plan" and is not happy. She is crushed when it seems that Grayfia is one for Issei.
• Ms. Fanservice: Female Fallen Angels are renowned for having very seductive bodies and Akeno's naturally sexy disposition, plus having the largest breast size in the series, only enhances this fact. Azazel himself stated that Akeno was particularly seductive even for a Fallen Angel.
• Naked Apron: She wears on in an OVA during her competition with Rias to seduce Issei by acting as a cheating wife.
• Ninja Pirate Zombie Robot: A miko who is also a Fallen Angel and a Devil.
• Nom de Mom: She goes by her mother's last name, Himejima, since Baraqiel has no last name.
• Number Two: She is the first servant and friend Rias made in the human world, as well as the Occult Research Club's Vice-President.
• Onee-sama: Along with Rias, Akeno's referred to as one of the "Two Great Ladies of Kuoh Academy".
• Passing the Torch: After Akeno's graduation, Kiba replaces her as the club's vice president.
• Playing Card Motifs: In the ending theme of the Season 1 anime, Akeno is shown as the Queen.
• Please, Don't Leave Me: Says this tearfully to Issei after seeing him return from near-death.
• Put the "Laughter" in "Slaughter": She has a habit of laughing or giggling while engaging in violence. But, most prominently, when Issei offers to take her out on a date as a reward for defeating an opponent, Akeno's immediate reaction is to explode in power while giggling uncontrollably.
• Raven Hair, Ivory Skin: She has black hair and white skin.
• Reasonable Authority Figure: Akeno, as the club's vice-president, is sound in judgment and willing to listen to her friends in the ORC as well as Azazel, even when she initially doesn't trust him.
• Red Baron: "Priestess of Thunder", and later "Priestess of Lightning" after mastering Holy Lightning.
• Red Oni, Blue Oni: The Blue Oni to Rias' Red Oni.
• Romanticized Abuse: A bonafide sadist, unless it's Issei, at which point she becomes the masochist for him and only him.
• Sex Is Violence: Akeno really enjoys combat. Some of the expressions she wears in the manga go well beyond "suggestive".
  • This is one of the few things that had to be bowdlerised in the anime. During the first fight against a stray devil, Rias tell Akeno to back off when she starts torturing it. In the novel, Rias just stands back and waits for Akeno to "calm down".
• Sexophone: Ryosuke Nakanishi's leitmotif for Akeno in the anime is a calm, jazzy saxophone piece. This is nearly played straight in New when Issei has to have his excess dragon ki "removed" by Akeno. As soon as she enters the room, the leitmotif starts... Plenty of sucking to be had.
• Shameless Fanservice Girl: Akeno, being Nephilim, is very much in touch with her perverted side and has no problem showing off her body in general, but especially for Issei.
• Single-Target Sexuality: She loves only Issei, but doesn't mind sharing him with other girls.
• Skinship Grope: Gropes Rias at the swimming pool of the Gremory household. She also gives quite a few to Issei as well.
• Sins of Our Fathers: Many of Akeno's relatives are appalled by the discovery that Akeno is a Nephilim.
• Smug Super: Always puts up a smile in battle.
• Soft-Spoken Sadist: Even though she's definitely one of the good guys.
• Spit-Trail Kiss: She gives one to Issei in his daydream in the first season's second short; bonus points for being a CPR. She then gives him one for real in Volume 22.
• Stepford Smiler: She can be a smiling and cheerful girl. However, bring up her Dark and Troubled Past or harm Issei, and she'll electrocute you to death.
• Stripperiffic: Her Fallen Angel Mode has skimpy clothes.
• Strong Family Resemblance: She looks almost exactly like her mother Shuri, especially in her later years.
• Tareme Eyes: Her eyes are large and droopy.
• The Tease: Oh so much. As this is her default setting, even normally innocent teasing can be taken as flirty. Azazel noted that for someone with Fallen Angel blood in her, a race that is naturally very seductive already, she is extremely seductive.
  • As her love for Issei blossoms, she eventually no longer teases him, but flirts with a genuine desire for furthering her relationship with him.
• Technicolor Eyes: She has violet eyes, which hints at her being a Nephilim.
• Too Kinky to Torture: Many scenes (mostly anime-original) involving the girls getting victimized in lewd ways (like slime dissolving their clothing, or monsters with tentacles) have her enjoying the experience.
• Trauma Button: Her PTSD is triggered the moment she hears from Kokabiel that she is the daughter of Baraqiel in Volume 3 and later when she meets her father face-to-face by the time of Volume 7.
• Violently Protective Girlfriend: Though not his "Official Girlfriend" like Rias, Akeno will be prepared to zap you if Issei gets injured.
• Virgin Power: She took advantage of this to lure the Unicorn go near her. She then smacks said unicorn and the group takes the unicorn's horn.
• Walking the Earth: After Shuri's death, Akeno uses her powers to help people while traveling throughout Japan. That is until she heals a devil that belongs to the Gremory Clan and befriends Rias...
• What Beautiful Eyes!: Look for yourself. (slightly NSFW)
• Yamato Nadeshiko: When not in sadist mode, Akeno comes off as an ideal Japanese woman due to her long black hair and gentle smile. Not to mention she is a great cook like Asia and Rias and her politeness and devotion to Issei and her teammates. In fact, Issei refers to her as such when he first saw her in the club building in Volume 1. However, Akeno has a fragile personality as she "depends" on men due to her sad past.
• Yin-Yang Bomb: She is a Nephilim turned Demon.
• You Can't Go Home Again: After Shuri's death, Akeno's unable to return to her family due to her Fallen Angel blood. Shin High School D×D: Volume 2 Life.4 Middle Game reveals that Suzaku Himejima let her go to Himejima house to strengthen the power she inherited from her mother.
• You're Not My Father: Akeno is unwilling to forgive Baraqiel for not being able to save Shuri and understandably refuses to think of him as her father. Fortunately, with Issei's help, they reconcile by Volume 7.

Yuto Kiba

Vice-President Yuto Kiba

Role: Knight
Species: Modified Human / Reincarnated Devil
Voiced by: Kenji Nojima (Japanese), Sean O'Connor (English)^{Foreign VAs}Amadeus Strobl (German)

I seriously won’t know what will happen when I am within this group.

Yuto Kiba is the school prince of Kuoh Academy and Issei's self-proclaimed best friend. He 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 of him and his friends.

---

• Ambiguously Gay: A lot of his later interaction with Issei puts his true sexuality in question (at least in the latter's head).
• An Arm and a Leg: In Volume 12, Siegfried cuts off his left arm, but Koneko, Ravel, and Asia help reattach it.
• Apologetic Attacker: Apologizes to his enemies whenever Issei breaks out a new perverted technique, much to the latter's frustration.
• Asskicking Leads to Leadership: He is a Master Swordsman and eventually gets promoted to the Club's Vice-President by the end of Volume 20.
• The Atoner: For participating in the Holy Sword Project in which his friends were killed during the experiments.
• Attractive Bent-Gender: In one Volume 13 short story, to Issei's horror, he realizes "Yumi" is his type of girl.
• Bash Brothers: He and Issei are this whenever they fight together.
• Beware the Nice Ones: Kiba is polite to pretty much everyone, even when Issei is still a Green-Eyed Monster regarding popularity among girls, but the former is furious at how the corrupt clergy had killed his friends in failed experiments to save face.
• Bishōnen: He's the pretty boy of the group. Lampshaded by Issei himself, who nicknames him "Pretty Boy Prince".
• Bond One-Liner: Delivers an epic one to Freed, after impaling the latter's head with his sword. Issei grudgingly admits how cool it sounded.
  Kiba: "You can continue howling to the Grim Reaper in Hell."
• Broken Ace: Has lots of fangirls compared to the unpopular Issei, plus he is intelligent and quite powerful. Despite his cool appearance, it is shown in Volume 3 that Kiba has an obsession with revenge, which makes him hot-tempered and irrational.
• Broken Bird: Kiba is a male example, in which he still feels the pain of being experimented upon back during his childhood, even well into adolescence.
• Broken Hero: He is a calm, confident and skillful Knight. His perpetual smile and collected demeanor hide the fact that he is the only survivor of the Church's Excalibur experiments, which were so brutal that left him traumatized and killed all his friends when he was a mere child and to top it off, he is an artificial human without a sense of self-worth; he is so deeply loyal to Rias simply because he has nothing else to hold on, something that Rias knows but is unable to fix. He admits to it in the Kokabiel arc. Though it gets kinda fixed with Issei and Koneko's friendship (with a healthy dose of Rias's Tough Love to help).
• Bros Before Hoes: This is the counterargument to Kiba's Ho Yay tendencies. It may cross with Bromantic Foil.
• Cast from Hit Points: A downside of Gram is that it can trim away at the user's lifespan it overused.
• Chick Magnet: He's popular with the girls at Kuoh Academy. His role as Darkness Knight Fang in the "Grabbin' Dragon" show garners a lot of attention from young mothers who watch with their children.
• Childhood Friends: With Tosca after he is reunited with her as one of the survivors of the Holy Sword project.
• Cynicism Catalyst: His participation in "The Holy Sword Project" caused him to become disillusioned with the Holy Swords in general.
• Dark and Troubled Past: He was originally called Isaiah, and was taken in by the Church and was chosen to be a part of a project called "The Holy Sword Project" supervised by Valper Galilei which led to the deaths of all of his friends and other participants when Valper decided to eliminate them, resulting in the latter's hatred of the Holy Swords namely Excalibur. After successfully escaping the facility with the help of his friends, he finally succumbed to the poison he inhaled. Lying on the ground, he was then found by Rias.
• Defrosting Ice King: During his initial days as Rias's servant, Isaiah was distrustful of Rias and all those related to her. One day, when giving tribute to his deceased friends, he was confronted by a stray Devil and fought a hard battle until his master, Okita, came to rescue him. After this event, he finally opened up to Rias and took up the name Rias thought of specifically for him, "Yuuto Kiba".
• Deuteragonist: Half of the series's point of view is through his eyes whenever Issei is not available.
• Dual Wielding: And sometimes, triple wielding.
• Effeminate Voice: Fitting his gentle disposition, he has a notably campy tone of voice compared to the more boyish-sounding Issei.
• Elemental Powers: "Sword Birth" can create magic swords that can have many elemental properties.
  • Playing with Fire
  • An Ice Person: Flame Delete
  • Casting a Shadow: Holy Eraser
    • Took this trope literally in Volume 12 when he briefly wields Issei's Ascalon, a holy sword, and Siegfried's Gram, a demonic sword.
• First-Person Smartass: Not as much as Issei, but he does have his moments whenever he narrates.
• From Zero to Hero: He starts as a nameless orphan who eventually becomes a Master Swordsman and a devil for the Occult Research Club.
• Fragile Speedster: By his own admission. And Issei points out later that Kiba's not blocking his attacks anymore whenever they spar.
• Gender Bender: In one Volume 13 short story, the group (minus Issei) underwent a gender change via Azazel's gender-swapping raygun.
• Get A Hold Of Yourself Man: He tells Issei to calm down and stay focused after he gets enraged due to Rizevim kidnapping his parents and having Ophis attacked, using the same words that Issei told him before facing Ewald. Issei thanks him but Kiba thinks that he should Think Nothing of It, due to the many times Issei helped him.
• Hair of Gold, Heart of Gold: While he initially has a hidden edge due to past trauma, Kiba has consistently been shown to be a kind and courteous gentlemen, with this becoming fully genuine after Issei and Co. help him through his issues. He also has a decent mop of short blonde hair.
• Handicapped Badass: Had one of his arms sliced off by Siegfried. He still kept on going, especially after Siegfried pushed his buttons.
• Heroic Willpower: He keeps fighting Siegfried, even after the latter cuts off his arm due to him being inspired by the promise he made with Issei. It also managed to trigger a reaction in Issei's Evil Piece that allowed it to turn into Issei's Holy Sword; Ascalon.
• Heartbroken Badass: The loss of his friends in the Holy Sword Project sent him into a Heroic BSoD.
• Heroes Prefer Swords: He uses swords as his primary weapons.
• Heterosexual Life-Partners: It is noted that Kiba does show some interest in the opposite sex, he just considers his friendship with Issei more important.
• Hidden Depths: He owns a cooking vlog, called "Handsome Dude Does Cooking", that he manages in his spare time. Predictably, it's very popular among females.
• Hoist by His Own Petard: During his spar with Xenovia in Volume 3, his anger toward the Excalibur fragments she and Irina were wielding leads to him irrationally whipping out a BFS for brute force. Xenovia easily defeats him afterwards, pointing out that creating such a large sword cut down his vaunted speed.
• Idiot Hair: Easy to miss, but he does have a strand.
• I Owe You My Life: After Issei rescues him, he becomes indebted to him.
• It's Personal: He wants to avenge his friends' deaths due to them being killed in the Holy Sword project.
• I Shall Taunt You: He uses this to his advantage during his fight against Sonneillon, making him angry so that he starts attacking recklessly, thus making his attacks miss.
• Like Brother and Sister:
  • Has this relationship with Koneko.
  • He later acknowledged Rias as a Cool Big Sis.
• Master Swordsman: He attained the title of Shihan (Assistant Grand Master) courtesy of his mentor, Okita Soji's Tennen Rishin Ryu.
• Mentor Archetype: He trains Issei's children in the future, most notably Zen and Ex.
• Me's a Crowd: His second Sacred Gear when it was known that a user only gets to use one Sacred Gear at most.
• Mid-Season Upgrade:
  • The first one was the ability to use a second Sacred Gear; Blade Blacksmith, which is a holy sword counterpart of his original Sacred Gear; Sword Birth.
  • The second is Gram and the other Demon Swords he acquired after he defeated Siegfried.
• The Mind Is a Plaything of the Body: While Yuto is very Ambiguously Gay as a male, when he gender bends to Yumi, the attraction towards Issei is that much more apparent.
• Mr. Fanservice: 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.
• Nice Guy: Despite Issei's initial rudeness towards him, he still is as polite and encourages Issei more so than the rest of the Occult Club except for Rias.
• Oblivious to Love: He's as clueless as your standard shounen protagonist.
• Only Known by Their Nickname: "Yuto Kiba" is the name Rias gave him. Before that, he was called "Izaiya/Isaiah" as his Code Name during the Holy Sword Project stint.
• Only Sane Man: Considering that his fellow club members are a notorious pervert, a group of girls who'll eagerly jump over each other to appeal to said pervert's desires, and an (initially) extremely reclusive crossdresser, Kiba comes off as pretty down-to-earth in comparison. One noteworthy example is when the club members were spying on Issei's date with Akeno. He was the only one who didn't bother with a ridiculous Paper-Thin Disguise (like a hat with sunglasses, or wrestler mask) or trying to remain hidden, and waved a hand at him as if he was saying "sorry about this".
• Parental Substitute: Issei's future children look up to him as a father figure due to always being there for them while their actual father is a celebrity and never home.
• Personality Powers: He was trained to be a swordsman and hates Holy Swords at first - his Sacred Gear creates Demon Swords, their demonic counterpart. When he gets his Balance Breaker, the Sword of Betrayer by accepting his friends' deaths, moving forward and abandoning his hate for the Holy Swords, he can create a Holy Swords that doesn't harm Devils.
• Playing Card Motifs: In the ending theme of the Season 1 anime, there's a playing card theme, and Kiba is shown as the Ace of Spades.
• The Promise: 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. And then Issei did die (temporarily), making Kiba fulfill that promise.
• Positive Friend Influence: Thanks to Issei's help and overcoming Excalibur twice (first by defeating Freed Sellzen who was wielding the Fused Excalibur and later defeating Ewald Cristaldi, a master Excalibur wielder), Kiba has let go of his vengeance, choosing to focus on protecting his new comrades.
• Rank Up: After Akeno's graduation, Kiba takes her place as the ORC's vice-president.
• Real Men Wear Pink: He is noted to be a perfect gentleman and a very skilled cook. His dream after graduating from school is to open a cake shop.
• Red Oni, Blue Oni: The blue to Issei's red.
• Revenge: His reason for becoming a devil under Rias' service is to find and destroy all the holy swords.
• Revenge Before Reason: Kiba can become very irrational when angry, to the point it severely hinders his skills. After learning his lesson, he keeps Issei away from this trope in Volume 20 when Qlippoth kidnaps his parents and brutalizes Ophis.
• Ron the Death Eater: A very rare In-Universe example. Darkness Knight Fang, the Big Bad of the "Grabbin' Dragon" series, is based upon Kiba. Hilariously, his devil fanbase turns it right around into a Draco in Leather Pants.
• School Idol: Known as the school prince of Kuoh Academy.
• Screw This, I'm Outta Here: He escapes from "The Holy Sword Project" once his friends are killed. By volume 3, he decides to leave Rias's team behind to avenge his friends' death.
• Sobriquet Sex Switch: In one Volume 13 short story, Yuuto turns into a girl named "Yumi".
• Spontaneous Weapon Creation: His Sacred Gear, Sword Birth, allows him to create numerous Demon Swords of different attributes according to his will.
• Stepford Smiler: Throughout the first part of volume 12, coping with Issei's apparent death better than the girls, though he was still clearly devastated.
• Survivor Guilt: Due to being the sole survivor of the "Holy Sword Project".
• Switching P.O.V.: This trope occurs in several chapters of the Light Novels where the story is told from his viewpoint over Issei's; the switches are usually for chapters that aren't titled Life.
• Trauma Button: Any kind of holy swords or mention of the Holy Sword Project will trigger an attack of PTSD. He gets over it by the end of volume 3.
• Unwitting Pawn: For "The Holy Sword Project", which involved all of his friends getting killed trying to wield the swords.
• Weak, but Skilled: 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 lampshades that he's the only technique user in a group full of power-types.
  • This has begun to change after volume 12 where he gets control of Gram and the other demonic swords that Siegfried possesses. While he is their owner, using Gram puts a strain on him, limiting his ability to use his brand new BFS in a fight, but he is slowly getting to the point where he will be both strong and skilled. In contrast, Xenovia starts considering the use of techniques after volume 14 so she, too, might reach his level someday.
• Wham Line: At the end of Volume 11.
  Kiba: "That day, we lost Issei."
• What the Hell, Hero?: There is a played for laughs example during the Rating Game with the House of Phoenix, when he first witnessed Issei's Dress Break. He apologizes to his current opponent for his teammate's perversion, irritating Issei.
• Yin-Yang Bomb: His Balance Breaker, Sword of Betrayer, is both a Holy and Demonic sword.

Koneko Tojo

Koneko Tojo, born Shirone

Role: Rook
Species: Nekomata / Reincarnated Devil
Voiced by: Ayana Taketatsu (Japanese), Jad Saxton (English)^{Foreign VAs}Elke Appelt (German, 2014-16), Heike Beeck (German, 2020-present)

...Are you thinking of lecherous stuff again, Ise-senpai?

Koneko Tojo is a nekomata and Kuoh Academy's mascot. She's in the care of the House of Gremory. Her real name is Shirone and she is the sister of Kuroka, who killed their master in self-defense after being subjected to experiments.

---

• A-Cup Angst: She reacts violently when Freed calls her a "little girl." She goes into a chilling Tranquil Fury when she hears Issei praise a demon plant that produces fruit that makes women's breasts bigger. She explains that she feels this way about herself when offering to restore Issei's lifespan with senjutsu via sex.
• Afraid of Their Own Strength: She is afraid of using her Nekomata powers because she fears they will go out of control like it happened with her sister (or so she thinks).
• Animal Jingoism: She has a cat motif, while Ravel has a bird motif; cats and birds generally get along poorly.
• Animal Motifs: As part of her cat motif, her true form has a tail and cat ears.
• Aren't You Going to Ravish Me?: Despite having a strong dislike for perverted behavior, in volume 3, she states that not being looked at pervertedly gives her complex feelings.
• Babies Ever After: In the future, she has a daughter with Issei, named Shirayuki.
• Badass Adorable: She may be adorable, but she has some fight left in her.
• Bakeneko and Nekomata: Whenever necessary, Koneko can transform into her true form: a less humanoid nekomata with cat ears and white tails.
• Big Eater: She's nearly always seen snacking, to the point people worry when she goes a whole train ride without a bite to eat. Despite this, she maintains a tiny frame. Those feats of insane strength must be pretty good at burning calories.
• Broken Bird: After her sister (allegedly) went berserk and killed her master, she was hunted down out of fear that she’d also lose control of herself. Rias saved her by making her part of her peerage, but her pursuers as well as her sister’s abandonment left her near-emotionless and afraid to tap into her natural Nekomata abilities for some time.
• Cain and Abel: She is the Abel to her sister Kuroka's Cain. Subverted, when it is later discovered that Kuroka killed her former master to protect Koneko from being experimented on.
• Can't Catch Up: This is a major part of Volume 5, made worse by how the only way she feels she can catch up is to use her Nekomata powers which at the time she was too afraid to use.
• Catchphrase Insult: Koneko says "You're the worst" whenever Issei reaches a new level of perversion.
• Cats Are Snarkers: She may be a nekomata, but she has a sarcastic and witty personality.
• Cat Girl: In thematic appearance as well as actual lineage.
• Character Development: She used to get angry over any of Issei's perverted antics and invokes Pervert Revenge Mode on him. Now she gets fussy only when his perverseness isn't directed towards her.
• Child-Like Voice: Koneko is notable for having a child-like appearance compared to her more well-endowed peers, Rias and Akeno, and has a very high, endearing voice to match that appearance.
• Clingy Jealous Girl: Can get jealous when Kuroka, Ravel, or the rest of the girls get too close to Issei.
• Crutch Character: She ends up as the weakest combat unit and eventually asks Kuroka for help to get stronger.
• Cute Bruiser: Don't let her cuteness fool you, she can still kick your ass when she has to.
• Dark and Troubled Past: After losing her parents, she and her older sister, Kuroka, were later taken in by a Devil who reincarnated her sister as one of the members of his peerage. However, Kuroka's power as a Nekomata supposedly soon grew out of control, eventually causing her to kill her master and become a Stray Devil. Following the incident and the failed manhunt that came after, Shirone was sentenced to death by the Devils in hopes of preventing another incident like Kuroka's from happening. However, Sirzechs Lucifer protected her and left her under his sister Rias's care.
• Defrosting Ice Queen: Initially harsh to Issei, witnessing his determination and strength eventually helps her warm up to him, to the point where she falls in love with him and once suggested having sex with him.
• Dub Personality Change: At least in the first season, her personality is far more indifferent and snarky in the dub. For example, when Issei and Kiba are about to head to a church to save Asia, they ask Koneko if she'll come. In the original, she responds that she'd be too worried to let them go alone. In the dub, she says she's got nothing better to do in a nearly sarcastic tone.
• Et Tu, Brute?: Her reaction to Kuroka double-crossing her after she killed their abusive master is of utter shock.
• Everyone Has Standards: Koneko made it clear that she was unwilling to forgive Ravel for causing trouble to Issei and Rias during their Rating Game, but they eventually befriend each other over time.
• Fanservice Pack: In the later anime adaptations, she's given a significantly larger bust than what she has in the manga and novel illustrations.
• Fantastic Slurs: She often calls Ravel a "wussy roast chicken princess" to the latter's annoyance.
• First Kiss: She shares her first kiss with Issei by the end of Volume 24.
• Full-Contact Magic: After she embraces her Nekomata heritage, she learns to combine Senjutsu and Youjutsu with her original hand-to-hand combat, enhancing her strength and inducing more internal damage to her opponents.
• Glacier Waif: Contrary to her small stature, her status as a Rook gives her specialization in brute force.
• Half-Human Hybrid: Her mother was a nekomata, while her father was a human. However, nekomata offspring with humans are still full-blooded nekomata.
• Hair Intakes: Befitting her cat motif, her hairdo has a pair of "cat ears". Her true nekomata form has actual cat ears.
• Heroic RRoD: Her Shirone mode counts as after a few minutes she is exhausted. Although Azazel claims that with time, it won't be a problem.
• Hidden Depths: She's a fan of rapping and shows it off to Issei.
• Image Song: Jounetsu-Unbalance
• Intimate Healing: She does this for Issei to recover his lifespan. The fact that she does it happily is a sign of her growing feelings for him.
• I Shall Taunt You: She had no problems taunting Ravel by referring to her as a wussy roast chicken princess.
• It Was a Gift: One of her cat hair clips is from Rias, while the other is from her mother and contains data about producing Super Devils.
• Jailbait Wait: Issei invokes 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.
• Lady Swears-a-Lot: The anime's English dub gives her an even fouler mouth than Issei, which reaches new heights when it comes to her rivalry with Ravel. Ironically, she tends to use polite keigo in the Japanese version.
• Like Brother and Sister: She and Kiba have no romantic attraction to each other, but both of them are still incredibly close, with Koneko personally being incredibly worried and determined to help during Kiba's Revenge Before Reason episode.
• Little Bit Beastly: In her Nekomata form, she grows a pair of white cat ears and a pair of matching white tails.
• Little Miss Badass: She might be 138 cm/4'6'', but she is a Rook and isn't someone you want to mess with.
• Little Miss Snarker: She's the shortest girl in the main cast, has a dry wit and often speaks in a deadpan tone.
• Masculine Girl, Feminine Boy: Koneko's is the Masculine Girl to Gasper Feminine Boy. Koneko is the Pint-Sized Powerhouse while Gasper is the Wholesome Crossdresser.
• Mating Season Mayhem: Goes into heat just like a cat. Unusually for the trope, the fact this is her instinctively trying to get pregnant is actually addressed and, with her tiny frame, acknowledged as a bad thing.
• Meaningful Rename: In Volume 24, she takes back her original name Shirone but keeps her surname Toujou and she still uses Koneko as another name.
• Mighty Glacier: She has some of the highest direct physical strength in the Occult Research Club, and the only one that comes close to matching her in toughness is Issei, but her mobility is extremely lacking, causing her to have difficulties against flying opponents and those light on their feet.
• My Instincts Are Showing: Played with. She actually seems to enjoy letting her catlike side out and using meows now and then, but suppressed it out of fear over her powers. Despite coming to terms with herself, she still only lets them show in private in front of Issei.
• Mystical White Hair: Her white hair hints at her supernatural nature as a Nekomata.
• The Nicknamer: She refers to Ravel as "roast chicken", given the latter's animal motif is the Phoenix.
• Older Than She Looks: Just like all the devils reincarnated before the series began, but she gets bonus points for looking like a particularly small underclassman.
• One Head Taller: With Issei, who is 170 cm/5'7'', while she's only 138 cm/4'6''.
• Only Known by Their Nickname: Koneko isn't her real name, rather it's Shirone.
• Parental Abandonment: She and Kuroka lost their parents as children. Volume 24 reveals that it was even worse than that, and their father really never even acknowledged them as his children, but rather thought of them no more than as kittens a pet cat may have.
• Pervert Revenge Mode: She has limited tolerance for Issei's perverted nature because she's well aware of his antics. She grows out of it though once she falls in love with him. She even wanted to help recover his pervertedness when he lost it because she didn't want him to lose interest in her.
• Pint-Sized Powerhouse: Her small size is inversely proportionate to her titanic strength. This is justified because her Evil Piece is a Rook, which gives her incredible strength and defense.
• Playing Card Motifs: In the ending theme of the anime's first season, Koneko is shown as the Jack.
• The Quiet One: She usually doesn't talk and if she does is to snark.
• "The Reason You Suck" Speech: She gives one to Ravel in volume 10 when, after they meet again, she reminds her of what she did to Issei and Rias. This doesn't sit well with Ravel.
• Rei Ayanami Expy: Pale skin, short white hair, golden eyes, petite, is not human, appears cold and soft-spoken and eventually warms up to the main character.
• Sexier Alter Ego: Her Shirone Mode transformation is noted to be much more attractive then her normal state, due to being taller and possessing a bigger bust. Issei notes that Koneko will resemble her Shirone Mode when she grows up, much to his excitement.
• Shaking the Rump: In the first season's ending, even reaching Memetic Mutation levels.
• She Is All Grown Up: Gain the ability to transform into an Older Alter Ego, called "Shirone Mode", which allows he to fully utilize her Nekomata power. It is noted that she resembles her sister Kuroka in terms of appearance, height and bust size, with the only difference being their hairstyles and hair color.
• Sibling Yin-Yang: With Kuroka. They even have contrasting hair colors.
• Signature Headgear: It's only fitting that the resident Cat Girl wears a black cat-shaped hair clip on both sides of her hair.
• Soul Power: Senjutsu in a nutshell. It's not as destructive as demonic power or magic, but can slip past the opponent's defenses and damage their life force.
• The Stoic: Speaks in a deadpan tone, usually preceded by ellipses in the light novels, and most events don't impact her much.
• Sugar-and-Ice Personality: She appears cold, distant, and snarky. However, she is a sweet girl once you gain her trust.
• Super Mode: "Shirone Mode" in volume 16, in more ways than one.
• Supernatural Gold Eyes: She has golden eyes and she is a Nekomata.
• Super-Strength: Contrasted strongly with her build.
• Sweet Tooth: Least in the anime, she's fairly often seen nibbling on snacks. Mentioned when the Club is off to the faction meeting, and Koneko prepared a box of snacks while she and Gasper wait - Issei privately thinks they're all for her.
• Title Drop: When trying to name the organization that will fight against Rizevim Lucifer's group, she names it the D×D.
• Token Mini-Moe: She is the smallest character in the main cast, at least until she is joined in this position by Ravel, Gasper and Ophis.
• Tomboy and Girly Girl: Koneko is the Tomboy to Ravel's girly girl.
• Unprovoked Pervert Payback: Played with. Early in the series, Koneko tends to step in to hit or insult Issei whenever he does something perverted. While her idea of what's perverted is reasonable, but she also tends to jump in when the subject of Issei's antics is unbothered, receptive, or even reciprocating. As she warms up to him and comes to terms with herself Koneo eventually explains to him that being a flat young lady competing for his attention with tall, buxom rivals gives her complicated feelings on the matter; she's aware that taking out problems with herself and other girls on him is unfair and isn't proud of her behaviour.
• Vitriolic Best Buds: With Ravel; their relationship is compared to a cat and a bird, as pointed out by Azazel.
• When She Smiles: Koneko is so cute that every home should have one. See for yourself◊.
• Willfully Weak: Her older sister Kuroka killed their master. Not wanting to become like her, Shirone sealed most of her powers until Issei convinces her otherwise.

Irina Shido

Irina Shido

Role: Ace of Spades
Species: Human / Reincarnated Angel
Voiced by: Maaya Uchida (Japanese), Kristi Kang (English)^{Foreign VAs}Nicole Hannak (German)

I'm not a self-proclaimed angel, I'm the real deal!

Irina Shido is Issei's childhood friend and an exorcist of the Catholic Church like her father Toji. She returns to Japan to look for the Excalibur swords alongside Xenovia. At first, she doesn't like the idea that Issei is now a devil but comes to terms with it later. At some point after learning the truth about God, she leaves the Church and joins Michael as an angel under the designation of "Ace of Spades" and after Issei rescues Asia from Diodora, she joins the Occult Research Club.

---

• Affectionate Nickname: Irina often calls Issei "Darling".
• Ambadassador: Even after becoming an Angel, she often helps the Occult Research Club establish diplomatic relationships. When negotiations in finding the Excalibur go south, she's not afraid to fight enemies that may attack, such as when Kokabiel attacks Kuoh Academy.
• Angel/Devil Shipping: Her relationship with Issei is an In-Universe, literal example of this.
• Babies Ever After: In the future, she has a son with Issei, named Shin.
• Badass Cape: She wears a long cape just like Xenovia.
• Berserk Button: She used to laugh it off, but now she gets upset when someone puts "Self-Proclaimed" in front of any of her titles. Especially angel and childhood friend.
• Big Damn Heroes: Brings a projector that contains the Breast Dragon song Issei had to rehearse to snap him out of his Juggernaut Drive.
• Black-and-White Insanity: For a while, her thought process was "church good; heretics, fallen angels, and demons bad." It was to the point where she happily referred to Asia as a heretic when they first met to Issei's understandable anger, even ditching Xenovia when she joined Rias, despite Xenovia and Asia still being believers in God. Fortunately, she learned to perceive more grays eventually.
• Boyish Short Hair: As a child, she had very short hair.
• But I Would Really Enjoy It: She would jump on Issei's groin in a second flat, but her status as an Angel would lead to her fall in case she outwardly expresses her carnal desires. Archangel Michael tried to circumvent this by creating a special room to let express her lust, but that only almost worked.
• Celibate Heroine: She tries to stick to this trope as explained above, due to the Church's teachings about sexuality as well as the risk of becoming a fallen angel if she lets her urges show. Once she's given a special room that removes this risk, she pursues Issei as aggressively as the other girls in his harem.
• Chekhov's Gunman: During Rias' Rating Game against Riser, the latter's Knight Karlamine caught Kiba's attention when she recalls fighting a Holy Sword user, who were targeted for his revenge at the time. During the rematch in a short story, that Holy Sword user is revealed to be Irina, who assists Riser's team to fight Xenovia.
• Childhood Friend Romance: She is in love with her childhood friend Issei.
• Cloudcuckoolander: Like Asia and Xenovia, she doesn't understand the aspects of reality.
• The Coats Are Off: Like Xenovia, she takes off her cape when she gets ready for battle.
• Comically Missing the Point: What does she say when she sees Issei groping both Xenovia and Asia in a shed in volume 6?
  Irina: "G... Go do it on a bed! This is too dirty, and the hygiene is terrible in this place!"
• Cool Sword:
  • She uses an artificial version of Kiba's Holy-Demonic Sword as her preferred weapon.
  • She later gets Hauteclere, the sword wielded by the friend of Durandal's original wielder.
• Covert Pervert: The angel race's strict dogma of sexual repression has left her with a hidden but extremely voracious sexual appetite, probably surpassing even that of Akeno and Kuroka in Issei's harem. This side of hers is seen in full force in Volume 19, where she straight-up gloats to Issei that anything Rias will try with him in the bedroom, she'll go one step beyond that.
• Enemy Mine: Despite being initially opposed to Devils and Fallen Angels as an exorcist, she and Xenovia still team up with the Occult Research Club to hunt down the Excalibur fragments.
• Energy Ring Attack: The anime gives Irina the ability to use halos of light to bind her enemies. In Shin Volume 4, she displays the ability to create rings of light which home in on the enemy.
• Et Tu, Brute?: She didn't react well when her partner Xenovia left the Church and reincarnated into a Devil. Fortunately, they patch things up when she learns that Xenovia had no choice but to leave the Church after learning highly confidential information.
• Fangirl: She and Issei used to be Super Sentai 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.
• Fanservice Model: As of Volume 2 of Shin High School D×D, she's featured on a Gremory-owned show as an underwear model alongside Asia and Xenovia.
• First Kiss: She kissed Issei back when they were kids.
• Forgotten First Meeting: 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, 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 their 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. Despite all of this Michael supports Irina's love for Issei, having gone so far as to create an alternate solution for her predicament in the form of a room that serves as a sort of pocket dimension where the angels' rules wouldn't be in effect allowing she and Issei to have sex in there to their heart's content without risk of her turning into a fallen angel.
• Forgotten Friend, New Foe: When they have first met again after many years, she was conflicted between killing or sparing Issei, since she's an exorcist and he's a devil (as well as an extreme pervert). After the Peace Conference, however, this is no longer an issue.
• Genki Girl: Not as hyper as some examples, but it's especially evident in the anime, where she's extremely, well, animated. If she's in the foreground of any shot, more often than not she's constantly moving.
• Girlish Pigtails: Her hair is usually tied into twin tails.
• Going Commando: Xenovia mentions that, when she comes into Issei's room she doesn't wear a bra. Irina tries to justify this by saying it's for health reasons.
• Heroes Prefer Swords: Like Xenovia, she uses swords as her weapons.
• Heterosexual Life-Partners: She and Xenovia are BFFs, even after the latter became a devil.
• Idiot Hair: She has a prominent sickle-shaped hair sticking out of the top of her head.
• In the Hood: Her white cape features a hood like Xenovia's, until she ditches it after she becomes an angel.
• I Shall Taunt You: She and Xenovia mock Asia for her exile back when they first met in volume 3.
• Light 'em Up: Using her light powers, she can create and morph weapons, akin Excalibur Mimic.
• Magic Knight: She is a swordsman, who additionally uses light-based powers. She is also learning regular magic under Rossweisse.
• Malicious Misnaming: It's a sore point for her if people keep referring to her as a "self-proclaimed angel".
• Marry Them All: Proposes to Issei immediately after seeing Xenovia do it, which apparently sets some kind of Rating Game proposal record. He accepts.
• Master Swordswoman: She's quite capable of using swords in battles.
• Morph Weapon: Her Excalibur Mimic, though she usually keeps it as a katana for simplicity. She later teaches it to Xenovia.
• One of the Boys: She 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, that his "best friend" is a girl all along.
• Patient Childhood Love Interest: While Irina has feelings for Issei ever since childhood, Irina was initially unable to pursue her feelings for Issei due to the fact that they were initially on opposite sides, and later due to her becoming an Brave Saint, which prevented her from induldging in physical intimacy, as Irina was forced to watch the other ORC girls such as Rias, Asia and Xenovia romantically pursue Issei. However, Irina was able to begin to engage in physical intimacy after getting a special room from Michael, as Issei reaffirmed that they are childhood friends and that he would always be at her side.
• Pet the Dog: By the time she meets Asia and Xenovia again, she apologizes to them both for her actions towards them.
• Phrase Catcher: "Self-proclaimed [title used to describe her]". Usually, it shows up as "self-proclaimed angel".
• Proper Tights with a Skirt: As part of her school uniform.
• She Is All Grown Up: Issei is first shocked to discover that his best friend from childhood was not only a girl, but one who grew up to be very beautiful as well.
• Skewed Priorities: When she catches Xenovia and Asia getting intimate with Issei in a shed, Issei expects her to call the act dirty. She only ends up calling the shed dirty and tells them to Get a Room!.
• Spontaneous Weapon Creation: She can use her light power to manifest a whip, inspired by her past use Excalibur Mimic.
• Token Religious Teammate: Another variant of this trope in that she's an angel compared to the still religious Xenovia and Asia being demons, but regardless is still a devout follower of God even after learning he's long dead.
• Tomboy and Girly Girl: Is actually in between the two characteristics. Compared to the other religious teammates, she's a girly girl to Xenovia with her more frilly and genki traits, but a tomboy to Asia due to her spunkiness. She used to be more of an overt tomboy as a child, sporting a Tomboyish Ponytail before she ditched them for girly twintails. Even Issei thought she was a boy as a kid.
• Tomboyish Ponytail: In the anime, she has her hair tied in a ponytail as a child.
• Unsettling Gender-Reveal: Issei thought of her as a young boy given how she had very short hair and only realizes to his shock that years later, Irina's actually a girl.
• Used to Be a Tomboy: As a child she was such a strong case of One of the Boys that Issei thought she was a boy, so meeting her again and seeing that She Is All Grown Up as a curvy, beautiful, and very feminine woman understandably causes a strong Unsettling Gender-Reveal for Issei.
• Valley Girl: The English dub gives her this sort of speaking pattern, emphasizing her ditzy thought processes.
• Vow of Celibacy: Due to being an Angel, she cannot become physically intimate, or else she will turn into a Fallen Angel. This dampens her attempt to escalate her relationship with Issei, much to her frustration. This is averted when she gets a room that allows her to have sex without turning into a Fallen Angel.
• Workaholic: Her job in heaven in the EX future takes its toll on Irina coming home late at night to collapse on the nearest couch out of pure exhaustion, to the point that she looks to be a future victim of Karoshi^note  "Overwork Death".
• What Measure Is a Non-Human?: A side story about when she first met Xenovia revealed that she was hesitant to seriously attack hostile humans, even if they were little more than mindless zombies after being fed upon by a Vampire. Xenovia's complete lack of hesitation to cut them down initially appalled her.

Gasper Vladi

Gasper Vladi

(after losing it) All of you should be killed. I'll even devour your souls.

Role: Bishop
Species: Dhampyr / Reincarnated Devil
Voiced by: Ayane Sakura (Japanese), Alison Viktorin (English)^{Foreign VAs}Sarah Alles (German)

Gasper Vladi is Rias' first Bishop and an extremely effeminate dhampyr who doesn't want to suck blood. Banished from his family as a child because of his powers, he is eventually transformed into a devil by Rias. He soon joins the Occult Research Club as a shut-in due to Rias trying to control his powers.

---

• Attractive Bent-Gender: He's a case of Dude Looks Like a Lady who is also a Wholesome Crossdresser, the combination of which results in many guys and some girls viewing him like a cute and pretty girl, even after learning he's a dude, and the story sees fit to treat him like a girl by giving him plenty of Male Gaze scenes.
• Badass Adorable: He's cute but he can still kick ass when he needs to.
• Badass Teacher: His number-one apprentice is Ernestine Galnstein, Issei's daughter with Elmenhilde.
• Beware the Nice Ones: He looks like he wouldn't harm a fly until he loses it against Georg. 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 Hellsing.
• The Bus Came Back: He was Put on a Bus after volume 6, but he returns four volumes later after Issei and his friends return from Kyoto.
• Chekhov's Gunman: 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.
• Cowardly Lion: Normally, he'd be afraid to do almost anything without Issei's help. Until he decides to take a beating for Xenovia, and later when he flips against Georg.
• Curb-Stomp Battle: Happens anytime he uses his Sacred Gear powers. And when he uses his true powers, Kiba outright narrated that his fight against Georg wasn't a fight at all.
• Dark and Troubled Past: Gasper's is probably the only one who can beat Akeno's past. How? His birth was very much troubled, having a fragment of Balor from the beginning by the time his mother delivered him, and she died because of the shock of giving birth of such an Eldritch Abomination. Then he and Valerie were exiled from the vampire society because of their powers and being considered as "different being", while the human society did so because they were still considered as vampires. Later, they are targeted by the upper echelons because of their powers and has to constantly live under tight surveillance until Valerie was able to cover his escape.
• Daywalking Vampire: Thanks to being half-human, Gasper can walk under the sunlight with no ill effects.
• Dhampyr: The child of a vampire nobleman and a human woman. He only occasionally needs blood (full-blooded vampires can't consume anything else) and can (but initially refuses to) go out in the sunlight as he pleases.
• Dude Looks Like a Lady: Not only does he like wearing girls' clothes, he naturally has a very effeminate body and face structure, so even when he wears male clothes people still often end up thinking he looks incredibly girly.
• Early-Bird Cameo: Like Xenovia, he also made a brief appearance in the Season 1 anime's post-credits during the announcement for Season 2.
• Effeminate Voice: The anime has Ayane Sakura give the Wholesome Crossdresser Gasper an incredibly cutesy voice that betrays his true gender. Even in the novels, Issei found his voice shrill and girly when he first heard it.
• Eldritch Abomination: When he becomes truly enraged and enters his true form, his surroundings plunge into the darkness he transforms into a living mass of darkness with several red eyes who can summon several deformed creatures which messily devour his opponents. It's later revealed that all this is the result of Balor, an evil god with a piece of his consciousness sealed within Gasper's Sacred Gear. He was born in a state like this, which understandably scared his human mother to death and cursed the surrounding hospital staff to die as well. His transformation gives enemies and allies alike a Mass "Oh, Crap!" reaction, but Balor, fortunately, treasures the Club as much as Gasper. EX reveals that he can contain the transformation and the darkness forms into a living shadow appearing from his body ala Shikamaru, subverting this.
• Equippable Ally: In Volume 24 he becomes one for Rias called "Forbidden Invade Balor the Princess" which lets her use the same abilities as his Sacred Gear. It was inspired by Sairaorg and Regulus using Balance Breaker together.
• Even the Guys Want Him: He somehow was able to collect fanboys despite them knowing that he's male.
• The Exile: He and Valerie were exiled by both the vampire and human societies.
• Friendly Neighborhood Vampire: He's shy yet good-natured Dhampyr who wants to drink as little blood as possible.
• Future Badass: In the future, he's revealed to have evolved Forbidden Balor View into complete Time Master powers, making himself a Super Devil, and has a different personality that scares Ex.
• Glowing Eyes of Doom: When he drinks Issei's dragon blood, his full power manifests.
• Hair of Gold, Heart of Gold: He's one of the nicest people in the Occult Research Club, rivaling Issei and Rias in his friendliness, and he has bright blonde hair.
• Half-Breed Discrimination: Born of a vampire nobleman and a human woman, Gasper is viewed as an outsider by both vampires and humans alike for being inferior to full-blooded vampires as well as his terrifying powers.
• Heartbroken Badass: 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.
• Hellish Pupils: Being a Dhampyr, Gasper's eyes are slitted at times and plays this straight when he snaps and transforms after Georg taunts of Issei's (temporary) death.
• Heroic Build: In the future. You wouldn't believe that he was once an effeminate crossdresser.
• 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.
• Magical Eye: His Sacred Gear stops time for whatever he focuses his sight on.
• Male Gaze: Hia feminine looks are frequently capitalized on by the story through him getting plenty of scenes dedicated to showing off his curves, being treated like an Innocent Fanservice Girl comparable to Asia, despite being completely male. It's to the point that he's the only guy who gets fanservice intermission cards in the anime.
• Masculine Girl, Feminine Boy: Gasper is the Feminine Boy to Koneko's Masculine Girl. Koneko is the Pint-Sized Powerhouse while Gasper is the Wholesome Crossdresser.
• Meaningful Rename: In Volume 25 his Scared Gear gets renamed from "Forbidden Balor View" (The Evil Eye that Stops the World) to "Aeon Balor" (The Evil-Eyed King Who Dominate the Space and Time) when it becomes a proper Longinus.
• Mentor Archetype: In EX, he teaches Ernestine Galnstein how to fight.
• Nice Guy: One of the nicest members of the main group.
• No Social Skills: Thinks cross-dressing is perfectly acceptable.
• Pointy Ears: His ears are long and pointy because of his vampire parentage.
• Prone to Tears: He's timid and sensitive, so it takes almost nothing to make him cry. One of the reasons Issei just can't stop going Stupid Sexy Flanders over him.
• Red Eyes, Take Warning: Being a Dhampyr, Gasper has red eyes. He's usually nice and harmless, unless someone manages to make him angry.
• Sealed in a Person-Shaped Can: 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 its name.
• Sensitive Guy and Manly Man: Gasper is the Sensitive Guy to Issei Manly Man.
• Shower Shy: He's very uncomfortable bathing with Issei and Kiba and even when Issei forces him to bath with them, Gasper keeps his Modesty Towel on. Issei calls him out on how unmanly he's acting, especially since Gasper wears the towel like a girl.
• Shrinking Violet: At the beginning of the story, he's terrified of being around too many people. He gets better over time.
• Stop Drowning and Stand Up: A brief gag in Volume 19 has him freaking out over being a vampire in water until Issei reminds him that he's only half-vampire and a reincarnated devil. Gasper replies "Ah, that's right" before standing up in the shallow pool.
• Story-Breaker Power: His ability is to stop time, lampshaded by Issei as "close to breaking the rules". On top of that, it becomes massively more powerful if he drinks even a drop of human blood. Luckily, for dramatic tension, he's Unskilled, but Strong (and even feared it for a long time).
• Stupid Sexy Flanders: Miyama-Zero and Ichiei Ishibumi sometimes give him the Male Gaze as if he were actually female instead of ludicrously effeminate. 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!"
• Superpower Lottery: There's a reason why his Bishop piece is mutated. And that's not counting what he can do without Forbidden Balor View. And it goes beyond that. It turns out that his Sacred Gear is an actual fragment of Balor itself, making it a Longinus level.
• Taking the Bullet: 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.
• Time Master: His future self-evolved Forbidden Balor View to be capable of using Balance-Breaker, which allows him to freeze time, travel hrough it, and send others through time. The exceptions are anyone of equal or greater strength to him.
• Time Stands Still: His Sacred Gear, Forbidden Balor View, can temporarily freeze anything he looks at.
• Tiny Schoolboy: While he stands at 150 cm/4'11'' tall, most of the girls in the Occult Research Club save for Koneko are much taller than him.
• Token Heroic Orc: Once the Club gains insight into Vampire society in Volume 14, they quickly come to realize how loathsomely arrogant the majority of the race is, and are baffled how someone as sweet and shy as Gasper could share their blood. For quite some time, the only other pleasant vampire was Gasper's childhood friend Valerie, who is also half-human.
• Took a Level in Badass: His decision after rescuing Valerie is to get stronger and later begins his training regime. He shows the results in EX.
• Unsettling Gender-Reveal: It's a minor Running Gag that any time a male character sees him for the first time, they'll mistake him for a cute girl, and when his true gender is stated, they'll state some variant of "Why is the world so cruel?" out of despair at him being a guy.
• Unskilled, but Strong: Usually, the ability to stop time would be insanely broken (especially if the user has a Mutated Piece, which denotes incalculable potential). That said, hatred and fear of his power caused him to not train it for a long time.
• Vampires Hate Garlic: As a Dhampyr, he has some vampire weaknesses, garlic being one of them.
• Vegetarian Vampire: Gasper doesn't eat meat products, and he rarely drinks blood.
• Wholesome Crossdresser: Nice, cute, feminine and wears the Kuoh Academy girls' school uniform despite being a boy.

Le Fay Pendragon

Species: Human

Voiced by: Minami Shinoda (Japanese), Natalie Hoover (English)^{Foreign VAs}Peggy Pollow (German)

Le Fay Pendragon is a powerful sorceress and the sister of Arthur Pendragon.

---

• Ascended Fangirl: After Vali's team is pardoned for their crimes, she becomes Issei's contracted magician. And eventual Wife.
• Apologizes a Lot: In part due to Kuroka always making a mess out of Issei's home when they moved in Volume 14.
• Babies Ever After: In the future, she has a son with Issei, named Mordred, who despite having the ability to wield Collbrande, decided to be a wizard. Part of the reason the ten other children travel to the past is to avoid him being retconned out of existence.
• Cute Witch: One of the nicer members of the Vali team.
• Fangirl: Of Issei when she asks for a handshake from him, revealing that she's a huge fan of his "Oppai Dragon" Show. Which she did in the middle of battle, mind.
• Hair of Gold, Heart of Gold: She has blonde hair and is a girl with an affable disposition.
• In Name Only: So far, she hasn't backstabbed her brother yet.
• Nice Girl: She's the nicest girl you would ever want to meet.

• School Uniforms are the New Black: Starts wearing one from Volume 9 onwards.
• Sibling Team: She fights alongside her brother Arthur.
• Sir Not-Appearing-in-This-Trailer: Le Fay barely appears in the teasers for Hero — and for good reason, as she appears towards the end of the first half of the series to help Issei deal with Cao Cao.
• Supreme Chef: If she's not around, the Vali Team defaults to cup noodles.
• Token Good Teammate: Not to the club, but rather to Vali Team, as her pleasant demeanor makes it almost impossible to believe that she was a former terrorist.
• We Used to Be Friends: With Meredith Ordinton, her friend and collegue from the Golden Dawn; who later allied with Hades and the Alliance of Hell.

Kunou

Species: Youkai
Voiced by: Sora Tokui (Japanese), Sarah Wiedenheft (English)^{Foreign VAs}Anni C Salander (German)

The daughter of Kyoto's Yokai Faction Leader Yasaka, Kunou is a kitsune that meets Issei during his trip to Kyoto, requesting his help in rescuing her mother from the Khaos Brigade. She later develops a Precocious Crush on him, and proceeds to move into the Hyoudou House to be with him. She would later enroll at Kuoh Academy as a 1st Year student in the Middle School Division, and become a member of the Occult Research Club.

---

• Antiquated Linguistics: She communicates in old-fashioned Japanese speech, highlighting her otherworldliness.
• Asian Fox Spirit: Like her mother Yasaka, Kunou is a kitsune, and possesses the ability to shapeshift. Due to her age, however, her true form is about as big as a kitten.
• Badass and Child Duo: She's the child to Issei's badass.
• Curtains Match the Window: Her gold eyes match her blonde hair.
• Cute Monster Girl: Besides fox tails and ears, she's a cute little girl.
• Easily Forgiven: After attacking Issei and his friends by mistake when they first enter Kyoto, she apologizes to them. Luckily, they forgive her shortly afterward and help her rescue Yasaka.
• Like Mother, Like Daughter: She inherits her mother's alternative fox form and her fire abilities, as well as her hair color.
• Miko: She wears the traditional shrine maiden attire.
• Mistaken Identity: When she's first introduced, Kunou thinks Issei and the Occult Research Club are the ones who kidnapped Yasaka. Luckily, they clear up the misunderstanding later on.
• Pals with Jesus: She becomes friends with Ophis, but knows her as a Dragon under the name "Phis" and is unaware she's the Infinite Dragon God.

• Precocious Crush: After Issei helps saves her mother Yasaka she gains one on him.
• Sixth Ranger: She moves into the Hyoudou Residence in Volume 22, which was hinted at prior in Volume 19.
• Super Mode: Developed one referred as Beast God, hers is called "Koryuu" (Fox Dragon) because of her friendship with Ophis.

Species: Modified Human

Tosca is an old friend of Kiba's and another survivor of the Chruch's Holy Sword project.

---

• Childhood Friends: With Kiba after she is reunited with him as one of the survivors of the Holy Sword project.
• Heteronormative Crusader: She's convinced that Issei and Kiba are a pair, and her past Church teachings make her uncomfortable with it.
• Older Than They Look: She's around Kiba's age, but looks around 12-13 years old due to being in suspended animation due to her sacred gear.
• Token Human: In a club containing Devils, Angels, Fallen, Yokai, Vampires, Valkyries, Grim Reapers, Magicians, and Dragons, Tosca is the sole member to be completely human, albeit one with a Sacred Gear.
• Unknown Rival: She is completely unaware that Tsubaki considers her a rival for Kiba's affection.

Former Members

Azazel

Azazel

Species: Fallen Angel
Voiced by: Rikiya Koyama (Japanese), Phil Parsons (English)^{Foreign VAs}Simon Derksen (German)

Do you think a world without God is wrong? Do you think a world without God would decay? I am sorry to say but that isn’t the case. Me and you as well are both healthily living like this. The world moves even without a God.

Azazel is the former Governor-General of the Fallen Angels. First appearing as Issei's contractor, Azazel joins the club as an advisor at Sona and Sirzechs's suggestion. Towards the climax of the fourth arc, he and the other faction heads are forced to seal themselves away so they may do battle with Trihexa. Although he is still capable of contacting the others thanks to Beelzebub, his loss is mourned by the Occult Research Club, especially Issei.

---

• The Ace: He's a Mad Scientist that reached several breakthroughs with Sacred Gears and created an artificial Sacred Gear. He's also an exceptional badass and leader of the fallen angels. To top it off, he's an extremely successful ladies man. Needless to say, he could be called perfect in every way.
• All Girls Want Bad Boys: How he's described by Issei.
• Ambadassador: He's sent to negotiate with the Three Factions for peace towards the end of volume 4. He luckily had his Sacred Gear with him when Katarea launches a full-scale assault on them. Then, in volume 9, he and Serafall start diplomatic relations between the youkai and the devils.
• An Arm and a Leg: He wins his duel against Katerea by using his light spear to chop off his left arm, which stuns Katerea long enough for Azazel to fatally impale her. He later replaces it with a new cybernetic arm.
• Artificial Limbs: Since losing his left arm to Katarea at the end of volume 4, Azazel wears a robotic arm made to look like his actual one.
• The Atoner: 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 inadvertently causing friction between Baraqiel and Akeno when her mother Shuri was killed by her own family. When father and daughter reconcile, he silently thanks Issei for helping him lift that burden.
• Authority Equals Asskicking: He's the Occult Research Club's advisor and one of the most powerful Fallen Angels alive.
• Badass Boast: Azazel delivers one to Vali after killing Katerea.
  Azazel: "Now then, Vali. What will you do? Shall I go at it again? Even if I have no armor and only one-handed, I can fight with you adequately."
• Badass Pacifist: The Club initially has a hard time believing that he's actually quite harmless given how much Fallen Angels antagonized them in the first few novels. During the Great War, the Fallen Angels led by Azazel were the first to cut their losses and pull out, and he makes every effort to ensure that war never breaks out again with the other factions, much to the frustration of Kokabiel and Vali.
• Badass Teacher: He's the advisor of the Occult Research Club and teaches his fellow members from time to time.
• Badass Transplant: Azazel replaces his missing arm he cut himself into a robotic arm that he's always wanted to try out.
• Berserk Button: Anyone bringing up one of his previous inventions, the Blazer Shining Aura Darkness Blade, is bound to set him off.
• Big Good: Even though Rias is the club's president, Azazel's millennia worth of expertise in training, Sacred Gears, and other mythologies mean that the club often takes orders from him.
• Bunny-Ears Lawyer: Like you would never believe.
• The Casanova: To put it simply, he has a harem. A thousand of them in fact. No, that's not the number of chicks he made out with. He has a thousand harems — and he's made out with every single one of them.
• Characterization Marches On: When Azazel was first revealed as the Fallen Angels' Governor-General, he was depicted with an almost sinister undertone, and was established to be the one who hired Raynare to murder Issei. Later on, however, Azazel is shown to be an absolute fanatic when it comes to Sacred Gears, a goofball that his assistant Shemhazai has to threaten into doing work, and a rather kind individual. Even his involvement in Issei's death comes across as odd in hindsight as Issei's Foil, Vali, is not only a half-devil but his surrogate son, making it seem odd he didn't just approach Issei and ask to study his Sacred Gear and possibly recruit him.
• Combat Commentator: For the Ratings Game match between Team Gremory and Team Bael.
• Cool Car: He also has an anti-Dragon missile and a Kill Sat.
• Create Your Own Hero: By having Raynare kill Issei, Azazel would be indirectly responsible for Issei's transformation into a devil and a respected hero of the Underworld.
• Curb-Stomp Battle: He easily overpowers and kills Katerea during the Peace Conference in volume 4, even after she had consumed Ophis' snake.
• Deal with the Devil: He makes a one-time pact with Typhon.
• Drives Like Crazy: He can drive normally, but he's willing to fire off a rocket-booster on his sports car in narrow roads.
• Easily Forgiven: It's pointed out that Raynare was Azazel's subordinate and her actions are his responsibility. He admits that's true, but Katarea and the Khaos Brigade launch an assault on Kuoh Academy before the meeting can go any further and at that point what he'd bring to the alliance is so valuable the big shots give him a free pass.
• First-Person Smartass: Whenever the narration goes to him, he's pretty snarky.
• The Friend Nobody Likes: The Occult Research Club initially despised him, since he was the head of the Fallen Angels who antagonized them early in the series and then suddenly introduced as their advisor on Sirzechs's request. Akeno was the most hostile because Azazel inadvertently caused her strained relationship with Baraqiel while Issei warms up to him fairly quickly with their shared perversions (though he's still often unwillingly subjected to Azazel's zany experiments).
• The Gadfly: Azazel loves trolling Issei for the hell of it.
• Genius Bruiser: He can kick ass and he can also study how to kick ass.
• Handicapped Badass: Even after replacing his left arm with a robotic one, Azazel's strong enough to stand up to the world's most powerful villainous factions.
• Heroic Sacrifice: A non-fatal example, but by the end of volume 21, he seals himself to help suppress Trihexa.
• Incoming Ham
  "It's! HERE!" (After remembering Issei and Tannin's conversation after the latter accidentally summoned the breast fairy)
• Ironic Echo: He warned Issei and the rest of the group not to make enemies of Hades. In volume 12, he, Sirzechs, and Dulio confront Hades to make a complaint.
• I Shall Taunt You: He has no problems taunting his enemies to provoke them into fighting him.
• Large Ham: When he has Rias "in hostage".
• Laser-Guided Karma: He finally gets his comeuppance after getting away with making Issei a Butt-Monkey, oh so many times, by the group. Hilarity Ensues.
• Law of Inverse Fertility: He's been hit by this, hard. In volume 21, it is revealed that though he's "enjoyed" a thousand harems during his life, he does not have a single blood descendant.
• Life-or-Limb Decision: He chops off his arm to free himself from Katerea. He's quite casual about it compared to most examples of the trope and gets a replacement later.
• Like a Daughter to Me: Although Akeno's initially hostile to Azazel, he admits that he views her as a daughter, given his close friend Baraqiel is her father.
• Mad Scientist:
  • He's devoted to studying Sacred Gears, admitting that it's the only thing he respects his former God for after making him fall, and attempts to replicate the process with several artificial Sacred Gears. He got excited after seeing the Nemean Lion Regulus and demands to Sairaorg to bring that to his lab for studying.
  • The basis for replacing his arm with a cybernetic prosthesis, rather than, say, using his Sacred Gear research to heal it, is because he always wanted a robot hand.
• Major Injury Underreaction: He hacks off his arm using his light attack that supposedly is dangerous for him. He just brushes it off like it's nothing before he impales Katerea with his spear.
• The Man Behind the Woman: Raynare would never have murdered Issei if Azazel didn't let her.
• Mentor Archetype: He becomes the advisor of the Occult Research Club at the end of volume 4.
• Mentor Occupational Hazard: He seals himself to duel with Trihexa.
• Mistaken for Terrorist: He's accused of hypocrisy due to being a "terrorist" while suing for peace. Needless to say, he's not amused.
• Mr. Exposition: Having lived much longer than the rest of the Club combined, he's usually the one to explain how things work outside of the Underworld.
• Not So Stoic: After seeing Rizevim, he destroys a wall to show how understandably frustrated he is at seeing him.
• Parental Substitute: He's served as one to Vali for as long as they've been training together. However, it's Odin who officially adopts Vali because a former terrorist would publicly look better off under the care of a god than a fallen angel recorded as a villain in the Bible.
• Powered Armor: He uses it infused with Fafnir's spirit. Unlike other Sacred Gears, his is only artificial.
• Pre-Mortem One-Liner: After hacking off his left arm, he says "I'll give you an arm at least" before killing Katerea for good.
• Really Gets Around: Over his life, he's "enjoyed" one thousand harems. Not one thousand women, one thousand harems of women. To technically meet the definition, that's 3000 women, minimum.
• Reasonable Authority Figure: Azazel has a reasonable disposition. Given that, he's willing to form a peace treaty between the Three Factions and advise the Occult Research Club on their missions.
• Redemption Quest: This is his motivation for initiating the peace talks and joining the Occult Research Club. He clearly regretted his involvement in Akeno's life.
• Retired Badass: Retires from his position as governor of the fallen angels, then joins the Occult Research Club.
• Say My Name: When Indra reveals that he knows Cao Cao as a kid, he could only utter out "Indra!"
• Spanner in the Works: He's the one who negotiated with the Three Factions to form The Alliance in volume 4. It leads to them discovering and fighting the Khaos Brigade.
• Sudden Sequel Death Syndrome: It is hinted that he dies in the future and Kurenai continues his research. So, more like "Sudden Spin-off Death Syndrome." When Volume 21 was released, many readers would have guessed that he would sacrifice himself. They were right.
• Staring Down Cthulhu: He confronts Indra — a god.
• Token Good Teammate: Of all the Fallen Angels shown in the series, he's one of the very few good ones.
• Too Kinky to Torture: After participating in one of Akeno's S&M plays.
• Tragic Mistake: After sending Baraqiel out on a mission, which involved leaving Akeno and Shuri behind, the Himejimas decided to kill Akeno for her Fallen Angel blood. He deeply regretted this mistake.
• Trickster Mentor: To everybody, but more on Issei and Vali than everyone else.
• Tritagonist: If both Issei and Kiba aren't available or if the scene is a very serious matter, then it's usually through his point of view.
• What Would X Do?: When he has a run-in with Lilith, Ophis' clone he asks himself what Asia would do. He ends up offering her a chocolate bar.
