'''THERE WILL BE SPOILERS FOR THOSE WHO HAVEN'T READ THE LIGHT NOVELS! YOU HAVE BEEN WARNED.'''

Occult Research Club
Tropes relating to them:
 * Almighty Janitor: Everyone in the Club with the exception of Rias and Azazel are low ranked devils. Rias is currently one of the weaker members of the Club. You do the math.
 * Badass Crew: Hell yeah!
 * Battle Harem: Even if you include Kiba and Gasper. It gets lampshaded by the author himself at one point.
 * Five-Man Band:
 * If not in a Rating Game:
 * The Hero: Issei
 * The Lancer: Kiba
 * The Big Girls: Akeno, Koneko, and Xenovia
 * The Smart Girl and The Leader: Rias
 * The Chicks: Asia and Gasper
 * The Mentor: Azazel
 * Sixth Rangers: Irina, Rossweiss, and Ravel
 * Heroic BSOD:
 * Ragtag Bunch of Misfits: They have the princess of the demon world, a survivor of a horrible experiment, a child of a fallen angel who turned into devil who is also a priestess, three very ditzy believers of god, a nekomata that looks like Yuki Nagato, a cross dressing vampire, a Mad Scientist that is also the leader of the Fallen Angel side, a Valkyries that loves money and hates spending too much, a demon phoenix, and finally a very perverted former Ordinary High School Student turned devil who also is a dragon.
 * Pyrrhic Victory:
 * Switching POV: The story is usually told through Issei's perspective, however there have been other characters that have gotten a narration from their perspective instead. To date, the only ones who have switched point of views from Issei are Rias, Kiba (secondary narration if there's something going on with Issei), Azazel (when there's a discussion with the leaders involved), and Asia.
 * True Companions
 * Try Not to Die: When Xenovia and Irina were able to get out of the dimension caused by George, they tell Issei to survive.
 * Unskilled but Strong: Not them individually but their whole group in the rating games lack experience hence they often don't do so well against a team in a rating game. This is best exemplified in their match against Sona's group where they had a hard time with Sona's strategies and hence almost lost.

Issei Hyodou "The Pawn"
"Voiced by: Yuuki Kaji (Japanese)"

The primary protagonist of the series and is also called "Isse" by his peers. He gets a girlfriend early on in the story, goes on his first date with said girlfriend, and then gets killed by said girlfriend.

He dreams of being a harem king, unknowingly already in the middle of being one.


 * Abhorrent Admirer: In one of the short stories of Volume 8, it's revealed that  Needless to say, he's not amused.
 * Achilles' Heel: Notable in that he's got twice the number of weaknesses because he's both a dragon and a devil.
 * A Date with Rosie Palms: After Rias appears to him all of a sudden in volume 2 and then goes back to her home. Thankfully, the anime omitted that little detail.
 * Ascended Fanboy: He's a fan of Super Sentai shows alongside Irina, and he finally gets a show in hell called Breast Dragon. He's conflicted however whether he's happy about it or not seeing as it's embarrassing for him to have his show called "Breast Dragon", however kids do love it.
 * A Man Is Not a Virgin: Averted, much to his chagrin because he really wants to lose it but can't because of his indecisiveness.
 * Badass: Just to count the ways...
 * Badass Abnormal: Having Boosted Gear already makes him a lot more powerful, but with him being a devil, he becomes a lot stronger.
 * Badass and Child Duo: When he and Kunou were the only ones who got together when everyone got separated at Kyoto.
 * Badass Boast: "Buchou, Rias Gremory-sama’s virginity belongs to me!!" Said in front of hundreds of devils attending '
 * Another one would have to be "If you want to burn me, bring me a phoenix or a dragon!"
 * Badass Creed:
 * Another one would have to be "If you want to burn me, bring me a phoenix or a dragon!"

 * Badass Finger-Snap: When unleashing Dress Break.
 * Badass Pacifist: Would prefer talking rather than beating up his enemies.

 * Heartbroken Badass: His thoughts reveal that he's still traumatized after getting himself killed by his ex-girlfriend and also rejecting her beg for mercy when she gets killed by Rias.
 * Intimidation Demonstration:
 * One-Man Army:
 * Submissive Badass: He's even more powerful than any member of his group, however he's still going to follow Rias' orders no questions asked.
 * Took a Level in Badass: Took millions!
 * Underestimating Badassery: Seems like a lot of people think that he's not as badass as he's supposed to be. He proves them wrong all the time.
 * Berserk Button: Invoked by Vali to make him fight harder. It works too well.
 * A more powerful one is
 * A more powerful one is

"Matsuda and Motohama: Go to hell, you bastard!!!! Ise: (after hanging up) Well, I am going to hell."
 * Beat Them At Their Own Game:
 * Boom! Headshot!: Achieves this
 * Breath Weapon: He learns how to breathe fire
 * Can't Act Perverted Toward a Love Interest: Averted pretty damn hard. He'll still make lecherous passes even though
 * It should be noted that the girls like it this way, and constantly encourage said advances.
 * Chick Magnet: He's got (in order of who liked him first): Asia, Rias, Akeno, Koneko, Xenovia, Irina, Ravel, . That's not counting the numerous amounts of admirers he has and that's not including the guys who want him. According to Ddraig, dragons are Chick Magnets.
 * Chivalrous Pervert: As much as he wants to make any moves, he just can't touch Rias because she's too good, and Asia because she's too pure.
 * Combination Attack: Due to his Gift powers, he's able to amplify his ally's attacks and launch a more powerful version. To wit, he pulled off a Field of Blades with Kiba, amplified Power of Destruction with Rias, amplified Akeno's Holy Lightning and his personal favorite with Gasper: Time stopping plus Dress Break.
 * Crazy Enough to Work: Most of his powers are pretty much this.
 * Crazy Prepared: His entire fight with Raiser at the engagement party. That is all.
 * Then there's his fight with
 * Curb Stomp Battle: In the beginning, he's the receiver of this. Then he started training and now, he's delivering all the curb stomps to weaker devils. Just ask
 * Dark and Troubled Past: He treats it like it was one. It's actually hilarious.
 * Deadpan Snarker: He gets his moments, normally when talking to Matsuda and Motohama. One particulary funny example occurs when he tells them he is going to ditch them to go to Rias' home (In the Underworld).
 * Curb Stomp Battle: In the beginning, he's the receiver of this. Then he started training and now, he's delivering all the curb stomps to weaker devils. Just ask
 * Dark and Troubled Past: He treats it like it was one. It's actually hilarious.
 * Deadpan Snarker: He gets his moments, normally when talking to Matsuda and Motohama. One particulary funny example occurs when he tells them he is going to ditch them to go to Rias' home (In the Underworld).


 * He also does it (internally) when Rias can't tell who the Maou Rangers are.
 * Deadly Upgrade:
 * Death Glare: He usually receives this to the girls.
 * Despair Event Horizon: He crossed it when he thought
 * Determinator: Best exemplified with his fight against Reynalle and went on from there.
 * Drop the Hammer:
 * Estrogen Brigade Bait: After his Training from Hell with Tanninim, he has developed quite a good looking body that half of his female classmates have a crush on him, knowing that he's a pervert.
 * Even the Guys Want Him: To defeat him, that is. Vali, Sairaorg,
 * Evil Is Hammy: While he's definitely not evil, his actions whenever using Dress Break and Bilingual plus Gasper's Time Stop makes him one of these in the eyes of a female. Koneko even lampshades it that only villains ever get to be that hammy.
 * Fan Boy: Of Sairaorg after witnessing him settle a mess.
 * First-Episode Resurrection
 * First-Name Basis: He calls everyone in the group, aside from Kiba and Rias, by their first names. Rias however also wants to be called by her first name instead of "Club Leader", however Issei doesn't which frustrates her.
 * Foil: To Vali for having the greatest Red Dragon-White Dragon library and the fact that their origins are different (Issei's a devil who doesn't have any considerable past, while Vali's the descendant of the original Lucifer). Also, Issei is more of a pacifist and will talk with the past hosts of Boosted Gear, while Vali's more interested in dominating the past users of Divine Dividing.
 * Another one would be with him and Cao Cao. Both have companions who are willing to die for them but while Issei isn't willing to sacrifice anybody for his cause, Cao Cao will do anything i.e., brainwashing people for his cause.
 * Friend to All Children: Apparently, children are attracted to him for some reason.
 * Groin Attack: He gets hit after blocking a speeding ball aimed for Kiba.
 * Half-Human Hybrid: 1/3 human, 1/3 devil, and 1/3 dragon to be exact.
 * Harem Hero: 2A latter evolves into 2B.
 * Harem Seeker: His ultimate goal after getting convinced by Rias.
 * Heroes Want Redheads: Out of his harem, he loves Rias the most but he can't spit it out for fear of destroying their relationship (he was killed by his ex-girlfriend after all).
 * Heroic RROD: Because of the limits of his body, he cannot call out Ddraig's full power for more than ten seconds without sacrificing a body part.
 * Hidden Depths: He's good at sewing, something that surprises Koneko.
 * He also has a love for having a harem and have sexual relationships with his fellow club members
 * Idiot Hero: Zigzagged. Well he has his moments he is usually on top of things once someone explains it to him and is not nearly as lacking in commen sense as some of the other members of the Occult Club. He only gets really dumb when it concerns Love. He also gets smarter as the series goes on.
 * Informed Flaw: Everyone calls him talentless and he's often remarked as the weakest holder of Boasted Gear. At the start that makes sense but once he starts training he completely blows through the more "talented" members of the Occult Club in terms of both strength and the rate he grows stronger. While it's true that he trains hard Sairaorg trains longer and just as hard as him and he still surpassed him in the end. At this point it gets a little ridiculous when someone remarks him as weak or talentless considering how fast he improved.
 * Although to be fair, the ones calling him talentless nowadays are Azazel, Vali and Cao Cao. And even then, it's a compliment for them because they know Issei is a hard worker and is getting even stronger in a different direction.
 * Intergenerational Friendship: Lots of 'em in this series and he's always the youngest; the latest being
 * Ironic Echo: Him promising to Koneko that he'll never use Dress Break to his allies. For those who haven't read the light novels,
 * Jack of All Stats: Pawns have the secondary ability of "Promotion" if they are deep in enemy territory (in chess a pawn is promoted when it hits the last row on the opposing side of the board.) Which allows him to promote himself to any piece except a King, gaining that piece's abilities.
 * Large Ham: Every single time he uses Dress Break and Bilingual to his female opponents, he will be bringing ham.
 * Just how hammy was the introduction of Dress Break in the anime? He breaks out his devil wings, pulls off a pose not far off from any Tokusatsu genre, and lets loose with a finger snap. While Ominous Latin Chanting music is playing on the background.
 * Let's Fight Like Gentlemen: He insisted to Koneko that he fight Saji in a one-on-one match when Koneko tells him that it's a team battle. He then outright tells Koneko that if Saji wanted to, he could have used his Sacred Gear on her.
 * Lovable Sex Maniac: Everyone in his harem loves him and they're alright with his perverted antics.
 * Love Hurts: It takes him 9 volumes to get out of this and what does he get
 * Magikarp Power: How his left gauntlet works. Every ten seconds, his power doubles. Get it boosted long enough and he can even kill any diety. Of course, due to the long preparation, no one's gonna wait for him to power up completely and get their asses kicked.
 * Magnetic Hero: He attracts special people like crazy. Practically everybody important in this series had some form of interaction with him.
 * Male Frontal Nudity: In episode 2 and it's uncensored even though it's only in a single frame and even then, it's easy to miss it.
 * Me's a Crowd: Something Azazel experimented on him. 300 of him to be exact. And yes, the cover illustration for said short story is a Shout-Out to said movie.
 * Mistaken for Gay: After Kiryuu spreads the photo of Issei and Kiba singing a duet together, rumors of them having a relationship spread like wildfire. Doesn't help that Kiba sometimes even outright tells Issei that he'll protect him. Issei just thinks he's nuts.
 * Mistress and Servant Boy: He's the servant and Rias is the mistress.
 * Multi-Armed and Dangerous: He grows extra limbs, some of which are sword-like,
 * Multiform Balance: How Trianna works.
 * Fragile Speedster: Welsh Sonic Boast Knight gives up armor in exchange for speed.
 * Glass Cannon: Welsh Blaster Bishop has a long charge time but very destructive attacks.
 * Jack of All Stats: Normal Balance Breaker has no weakness but doesn't add any special power.
 * Lightning Bruiser: Cardinal Crimson Queen basically combines all 3 modes strong points without any of their weakness.
 * Mighty Glacier: Welsh Draconic Rook has heavy attack and defense but due to the extra armor in this mode speed is lowered.
 * Mr. Fanservice: All the Training From Hell more than pays off for Issei in terms of his looks, as all those muscles make his goal of scoring hot pussy way, way easier than before.
 * Mundane Utility: How he acquired Dress Break in the first place was to peel vegetables at a distance.
 * Naked on Revival
 * Nice Guy: Despite being a pervert he is one of the nicest people in this story.
 * Nice Job Breaking It, Hero:
 * Ninja Pirate Zombie Robot: A perverted high school student that is both a dragon and a devil.
 * No One Gets Left Behind:
 * Normally I Would Be Dead Now:
 * Nosebleed: Too many times to count.
 * Oblivious to Love: As much as he's perverted, he doesn't catch the fact that all of the girls in the club love him. Then again, he did get killed by his ex-girlfriend and it still traumatizes him.
 * Obvious Rule Patch: Every single time he makes up a new move, the Rating Games always outright ban that move after use the match. Doesn't mean he can't use it when he's not in a Rating Game though.
 * Papa Wolf: To all the girls, but ESPECIALLY Asia and Koneko. Just ask Kuroka and Diodora.
 * Person of Mass Destruction: His missed attacks can blow up MOUNTAINS.
 * Kiba even points out later on that whenever they train, it just feels so tiring to train with Issei because one hit from Issei will kill him.
 * The first time he uses Trianna Bishop ,he would have killed the entire Hero Faction if Cao Cao hadn't gotten them out of the way.
 * Porn Stash: Thinks he hid it pretty well until his mom blurts out where it's located at.
 * Power At a Price:
 * Powered Armor: Balance Breaker Boosted Gear Scale Mail
 * Power Perversion Potential: Half of his abilities works like this!
 * Dress Break: Anything he touches, he shreds off their clothing. Declared an illegal move in the subsequent Rating Games where technically, there are no rules.
 * The Nudifier
 * Bilingual: Yes, he can hear a woman's secret just from their breasts.
 * Punched Across the Room:
 * Defenestrate and Berate: In the anime  goes out a window instead, only to be hauled back in by Koneko.
 * Red Baron: Called by everyone else as Red Dragon Emperor. Then they changed it to Chichiryutei (Breast Dragon Emperor) after completing his Balance Break
 * Red Oni: To Kiba's blue.
 * Required Secondary Powers: He needs a lot of stamina just to be able to make Boosted Gear work properly.
 * Rivals Team Up: With Vali against Loki
 * Roar Before Beating:
 * Screams Like a Little Girl: He's the one who screams when he accidentally walks in on Asia while she was in the shower instead of the other way around.
 * Sealed Inside a Person-Shaped Can: Issei is the can to Ddraig.
 * Second Year Protagonist
 * Serious Business: If you want to put on a strip show for him,
 * Shoulder Cannon: His Illegal Triana Bishop form.
 * Shipper on Deck: Ships Saji to Souna.
 * Spanner in the Works: Wrecks his opponents plans like no tomorrow.

 * With Diodora:
 * Spit Take: When his mom asks him when is she going to have a grandchild ever since
 * Status Buff: How Gift works.
 * Straight Man: Pulls this off when Asia or Xenovia end up praying and gain damage.
 * As long as he isn't in his perverted antics, he's this to anybody. He's this to Rias when he recognized who the Maou Rangers were right away while Rias thought it was a new enemy. Also one to Bikou and Vali when they thought Mil-tan was a Catgirl. He even wanted to point out to Irina that although she's wanting to create a new club, she's still joining the Occult Research Club. And he also is this to Rossweiss
 * Superpower Lottery: Subverted. While one would think that having one of the strongest Sacred Gear that doubles your power every ten seconds would be a big win Issei himself is utterly talentless and has to compensate by going through Training from Hell to get stronger.
 * Technical Pacifist: Never kills anybody even though he beats the crap out of them.
 * Tender Tears: Yes, perverts are able to regard girls as people with feelings-hopes-and-dreams rather than just objects.
 * The Champion: For Rias; he'll do anything for Rias.
 * The First Cut Is the Deepest: Raynare's attempt on his life, he feels that even though he would like to pursue a relationship with any member of his unknown (to him) harem, he's scared that he would be rejected almost instantly.
 * The Heart: The occult club sticks together mostly because of him. In fact if he ever decides to leave and form his own group both Asia and Xenovia would go with him.
 * The Messiah: Even though he's a dragon-devil.
 * The Only One Allowed to Defeat You: Inverted.
 * "The Reason You Suck" Speech: Delivers this towards
 * Thou Shalt Not Kill: Hasn't really killed anybody outside of Rating Games and even then, no one dies in Rating Games anyway. He might beat them to a bloody pulp though.
 * Time to Unlock More True Potential: Well, it is a shounen series after all.
 * Transformation Sequence: When he puts on his Balance Breaker for the first time in the anime.
 * Transformation Is a Free Action: Yet somehow, no one attacks him while he's transforming in this form. Even Maou Ranger Red (Sirzechs) lampshades that it's a rule to never attack while the opponent is transforming.
 * Unskilled but Strong: His main problem once he actually starts getting stronger is that he lacks technique.
 * The Rival: While Vali is more likely his rival thanks to their Sacred Gears, he considers his true rival to be Saji.
 * The Worf Barrage: Possibly the weirdest one ever.
 * A more serious example would be his Balance Breaker Scale Mail. If you could break his armor that it indicates that your a threat to him. If you can't expect to be utterly destroyed in combat with ease.
 * We Do the Impossible:
 * Weirdness Magnet: He even lampshades that he's been attracting a lot of weird people lately.
 * What the Hell, Hero?: He's called out by the other members of his group when
 * When All You Have Are Rias' Breasts: Anytime Issei needs a serious power up, it's always going to be with Rias' breasts. Examples include:

 * Having a power up in the middle fighting the Hero faction? Push Rias' nipples that are glowing.
 * Already unconscious from ? Have Rias' breasts be glowing in crimson color.
 * Need to have more firepower when your so tired after using two Dragon Blasters and Gift?
 * World of Cardboard Speech: "Yes I am, a devil!"
 * Would Hit a Girl: Especially if it's his ex-girlfriend who just murdered his new friend!
 * Unskilled but Strong: His main problem once he actually starts getting stronger is that he lacks technique.
 * The Rival: While Vali is more likely his rival thanks to their Sacred Gears, he considers his true rival to be Saji.
 * The Worf Barrage: Possibly the weirdest one ever.
 * A more serious example would be his Balance Breaker Scale Mail. If you could break his armor that it indicates that your a threat to him. If you can't expect to be utterly destroyed in combat with ease.

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.

Diodora Astaroth
One of the six young devils who are participating in the Rating Games. He actually first appeared as the devil who Asia healed back when she was still in the church.


 * Adaptation Dye Job: While Diodora had blond hair in the original light novel series, his hair is dark green in the anime.
 * Ambition Is Evil: His ambition is to kidnap and have Asia join his harem.
 * Ars Goetia
 * Ax Crazy: Despite not cracking until his Villainous Breakdown, his obvious pleasure at raping and torturing Asia is a sign that he has not got a right mind.
 * Bait the Dog: When he first appears, he's an affable devil. Then it's revealed that he's a murderer and a rapist. After that, he tries to kidnap and rape Asia.
 * Berserk Button: He despises the idea of someone that's much stronger than him.
 * Big Bad: He is the main antagonist of Volume 6 until Shalba kills him.
 * Big Bad Wannabe: He is memorable for being the first villain that Issei completely overpowered. Unlike all the former villains who are all stronger then Issei.
 * Bullying a Dragon: Diodora decides to underestimate Issei's powers as the Red Dragon Emperor when he attempts to rescue Asia. It doesn't work.
 * Chekhov's Gunman: Was only mentioned as part of Asia's Backstory in the first volume before he makes his appearance.
 * Classic Villain: He represents Lust and Pride.
 * Complete Monster: One of the biggest ones in the series.
 * Crisis of Faith: Diodora actually gets off on causing these in his marks; finding a devout, well-respected holy woman like a nun and slowly breaking their spirits until they ultimately give in to despair.
 * Cuckold: Proposes to and attempts to kidnap and rape Asia, incurring the wrath of Issei.
 * Death by Irony: He gets killed after being overpowered by the Issei, the same person who helped rescue Asia, whom Diodora tried to pull a rescue attempt by killing Raynare before Issei stepped in.

 * Dirty Coward: When the club tries to rescue Asia, he threatens to use her as a Human Shield, before teleporting away snickering.
 * Disc One Final Boss: He's presented as one of the final main villains of the second story saga, but it's not until the finale of volume 6 that the true final boss turns out to be Shalba Beelzebub.
 * Engineered Heroics: He planned for Asia to get excommunicated by the church and also waited for Raynare to kill her, only for him to kill the fallen angel and revive Asia, thus appearing to be her "savior." The last part of his plan fails when Raynare is defeated by Issei and Asia is revived by Rias.
 * Evil Cannot Comprehend Good: Diodora's arrogance and relentless self-centeredness blind him to the idea that Issei will defeat him and cause his plan to kidnap and ultimately rape Asia to fail.

 * Evil Gloating: When the group confront him, he continuously taunts Issei about having kidnapped Asia, eventually crossing one too many lines and causing Issei to reach his Rage Breaking Point by threatening to rape Asia.
 * Evil Plan: He had planned to make Asia a part of his harem from the very beginning.
 * Eyes Always Shut: As part of his smug, polite facade. He opens them when he gets aggravated, like when Issei tries to pull him away from Asia.
 * Fatal Flaw: Diodora's pride and lust. He can't control his urges to rape and murder nuns, and couldn't stand being underestimated by Issei, and that's precisely how he lost in volume 6.
 * For the Evulz: He’s pretty much a scumbag for the sake of being a scumbag. He even drags the rest of the Occult Research Club into his business with Asia just to have more victims. This kills him in the end when he gets curb-stomped by an enraged Issei and is dispatched by Shalba as a result.
 * Faux Affably Evil: He may have been calm and polite in the Young Devils' Gathering, but it was only because he had to do it to cover his true motives, not to mention that he was clearly shown to drop his polite demeanor whenever not in their presence.
 * The Plan:
 * The Plan:

 * Badass: Oh hell yes! From his first appearance alone, you know he was going to be one of the biggest badass characters of the series.

Amano Yuuma/Reynalle
"Voiced by: Hitomi Nabatame (Japanese)"

Issei's ex-girlfriend and is responsible for killing Issei which starts off the plot.


 * Femme Fatale
 * Evil Costume Switch: Anime only.
 * Hotter and Sexier: The light novel and the manga version of her reveal was just showing off her wings. The anime however, got her to wear Stripperific clothes.
 * Meaningful Name: Although this is working without the component kanji (and, therefore, a way to look them up), "Yuuma" sounds like "Ghost Fiend"—and "fiendish" barely begins to describe her killing of Issei. Never mind her actually being a Fallen Angel...
 * Actually, she reveals she chose that name because "Yuu" means "night" or some equivalent, which was WHEN SHE PLANNED ON KILLING ISSEI!!
 * Smug Snake
 * Token Motivational Nemesis: To Issei. Subverted in that even after her death, he still looks back on the memories of his first date with her with warmth and fondness.
 * Why Don't You Just Shoot Him?: Averted when she and Issei met up again while Asia was with him. After Issei showed off his Sacred Gear, she just shoots him with a light spear in the stomach and mocks him because she thought he only had Twice Critical.

 * Knight of Cerebus: He's the first enemy that the ORC was completely incapable of beating, and he drops the bombshell that God Is Dead.
 * Obviously Evil: His face alone in the second PV of the second season looks like he fits more in the devil society than in the fallen angel group.
 * Its also a case of Fridge Brilliance, due to the fact that Angels in the Bible are known be terrifying in appearance.
 * Politically Incorrect Villain: Well, he is racist, after all...
 * This Cannot Be!: When he finds himself losing to Vali, who lampshades how stereotypical such lines are before finishing him off.
 * Wake Up Call Boss: Manages to become this for the entire (incomplete at that time) Gremory team. They could barely scratch the dude and it took Vali to beat the crud out of him.
 * We Used to Be Friends: Even though Kokabiel tried to start another war, the other fallen angels still think of him as a comrade and thought that what he did was stupid.
 * The Worf Effect: He both Worfs and is Worfed. The ORC could barely scratch him, establishing that while they are badass, they have a long way to go before they are major players power-wise. He is immediately one-shot by Vali, establishing him as a major player, power-wise.

An exorcist for the fallen angels, he first appears in the story in Volume 1 (Episode 3 of the anime) when he kills a human who has a devil contract saying that all devils and humans who contact devils must be killed.

He's both insane and aggressive, attacking whoever gets on his nerves, or simply catches his fancy when he's "in the mood."
 * Ax Crazy: Yep, he's a nutcase.
 * Ax Crazy: Yep, he's a nutcase.
 * Back for the Dead: After having been cut down in Volume 3, Freed would meet his ultimate end in Volume 6 at the hands of Kiba.
 * Blood Knight: Freed may be an exorcist, but he doesn't give a flying crap about God. The only reason he's an exorcist is so he can kill demons and slake his bloodthirst.
 * Body Horror: His body takes on the terrifying form of a chimera during his final appearance.
 * The Dragon: He plays this role to Raynare in Volume 1, then to Kokabiel in Volume 3, and again to Diodora in Volume 6, although it's up for debate as to whether he was really serving the latter or just looking for revenge against the Research Club.

 * Killed Off for Real: After being revived as a chimera, Freed dies permanently in Volume 6 when Kiba slices him apart nearly instantly.

 * Perpetual Smiler: Perpetual Smiler: Pretty much always has a twisted grin plastered on his face.
 * Recurring Boss: He attacks the Occult Research Club multiple times over the course of the story: In the first volume, when Issei visits a client who Freed had just killed, and again outside the abandoned church where he fights them to protect Raynare; In the third volume, when he battles Kiba and Xenovia for Kokabiel wielding the Excaliburs; and finally in the sixth volume, during the Rating Game against Diodora, having devoured two of Diodora's knights and become a chimera. Here, he is killed by Kiba.
 * Red Eyes, Take Warning: He has red eyes and is a villain.
 * Run or Die: After Raynare is defeated, Freed is forced to abandon the fight.
 * Screw This, I'm Outta Here: He heads for the hill when Issei defeats Raynare and Rias is about to kill her.
 * Sex Is Violence: He outright states that he's getting hard just from the "killing intent" in Akeno's gaze, and generally acts as if torture and murder are his favorite turn-ons.
 * Teen Genius: Was apparently an exorcist when he was 13 years old.
 * The Only One Allowed to Defeat You: Towards Issei for hitting his face.
 * Wake Up Call Boss: Played with. Issei hasn't really fought any battles yet (and the ones he was involved in usually ended up getting him killed, or at least hurt badly). But when he encounters Freed for the first time, he knows that he's outclassed and even Rias apologizes to him since they hadn't realized a rogue exorcist was around.
