Kyo Kara Maoh!



Shibuya Yuuri was an Ordinary High School Student with no truly outstanding features aside from his love for baseball. At least, he was, until he tried to break up the bullying of another student and was dunked in a toilet, which sucked him into another reality -- one in which his black hair and eyes marked him as the successor to the title of Maoh, or Demon Lord. Unfortunately for Yuuri, he has no knowledge of this kingdom, its customs, or how to go about ruling it... should he even survive to his coronation. Fortunately, he promptly meets a large number of hot guys willing to help him out.

Despite its sometimes serious veneer, Kyo Kara Maoh is first and foremost a comedy, though it grows into an adventure as the story progresses. Even the Yaoi Guys scenario of Yuuri ending up engaged to Wolfram is played for laughs -- please don't slap someone unless you mean it. Along with Wolfram's brothers (Gwendal and Conrad), their mother Cheri, and a few other noteworthy mazoku (lit.: demon tribe), Yuuri might just live long enough to be acknowledged as Maoh and bring peace to the world which is currently split along human/mazoku lines... But is fomenting peace really what a Demon Lord should be doing?

Kyo Kara Maoh started off as a series of light novels (ongoing), and was made into a manga series (also ongoing), a TV anime series, an OVA and a PlayStation 2 game. The details in each version are slightly different.

Remember to put character tropes on the character page.

""Maybe I should just kill you now; then you'd be mine forever.""
 * Aesoptonium: The Miasma in season 2 that causes everyone who is affected to stop trusting each other.
 * Accidental Marriage
 * was also a Childhood Marriage Promise. According to her.
 * A Child Shall Lead Them: Yuuri is only 15 at the beginning of the series yet is crowned the Ruler of a country.
 * The third season reveals that King Saralegui was also crowned at age 15.
 * Action Mom: "I am Jennifer of Yokohama!"
 * Amplifier Artifact: Morgif. Also at times, if you consider him an artifact (he's pretty damn old).
 * An Arm and a Leg
 * Arranged Marriage: Julia to Adelbert, although it's completely consensual and the two seem to genuinely love each other.
 * Nikola to that one guy she leaves at the alter.
 * The Atoner: Geigan Huber wasn't necessarily a bad guy, but definitely has shades of this.
 * Badass Normal: Conrad who, due to his human heritage, has no magical ability to speak of is widely known to be the greatest swordsman in the kingdom.
 * And his best friend, Yozak. Half-human spy and master of disguise.
 * And Miko (Jennifer), when she gets riled.
 * Barrier Maiden: Ulrike and Ondine
 * Beauty Contest: To Cheri's delight!
 * Bedmate Reveal: Wolfram has a bad habit of sneaking into Yuuri's bed despite his protests.
 * Beginner's Luck: Yuuri manages to kick ass and defeat his opponents without even knowing how, despite them having years of experience and training.
 * Berserk Button: God forbid you hurt some innocent people, lest you be served a delicious plate of hot JUSTICE by the Maoh.
 * Big Brother Instinct: Yuuri's brother Shori is obsessively protective of his "Yuu-chan".
 * To a lesser extent, Gwendal and Conrad are always looking out for Wolfram.
 * Bishie Sparkle: Wolfram (in one memorable episode) and Gunter.
 * Bishonen: . To the point where Yuuri seems to crush on him.
 * Black Knight: Gegenhuber von Briscella.
 * Blonde, Brunette, Redhead: Yuuri, the brunette, and his "family" in the other world (Wolfram, the blonde, and Greta, the redhead).
 * Also, the three maids.
 * Blond Guys Are Evil: . Wolfram is an aversion, but that doesn't mean he's nice.
 * Blood-Splattered Innocents: Yuuri when
 * Brainwashed and Crazy:  seems to get possessed an awful lot later on.
 * Call Back: The anime frequently calls back to scenes in the past, usually times when Conrad saved Yuuri's life. This happens so often in the latter part of season 1 that the same scene is called back to at least once an episode. Season 2 and 3 are also peppered with call backs.
 * Cast Full of Pretty Boys
 * Catch Phrase: "Normally, it's not my nature to threaten or kill, but I won't have any pity this time. I'll send you down a path of evil to make your own hell. Justice be done!" - the Maoh
 * Censor Steam: In the OVA #1, Yosak, Yuuri, and  are enveloped in just enough steam to hide the naughty bits...
 * A Chat with Satan:
 * Although technically that blends this trope with Pals with Jesus, especially once Season Three begins and keeps the pocket model.
 * A Handful for an Eye: Josak does this a lot.
 * Chained Heat: Yuuri and Gwendal are forced to spend an episode in the first season handcuffed together. They're mistaken for an eloping couple, and asked to say a few words of encouragement at a wedding.
 * Character Tics: Due to his years of knitting as a form of stress relief, Gwendel now makes knitting motions whenever he’s upset, even if there are no knitting needles in sight. They introduce this slightly before the actual knitting, so he does some really weird twitching there.
 * Chekhov's Gunman: In the first episode, a purple-haired girl gives Yuuri some water to drink. She also has a cameo in the opening credits. We find out much later that she's actually.
 * Chekhov's Skill: Yuuri's ability to play baseball, along with Conrad's ability to throw.
 * The Chessmaster: plan to  Does this count as an Ancient Conspiracy?
 * Chilly Reception: Gwendal all but ignores Yuri upon his arrival at the castle and Wolfram is outright hostile. Despite the fact that everyone else seems pretty happy about Yuri's coronation, these are two of the people who will play a major role in his Demon Kingdom life, so he still has to win them over.
 * Color Coded for Your Convenience: This series is really fond of this trope. The most obvious example are the main characters' uniforms: Yuuri is black, Conrad is brown, Wolfram is blue, Gwendal is green and Gunter is purple.
 * Although the colors don't match up with their personalities in any obvious way, so it's more like Limited Wardrobe Color Range
 * Close-Call Haircut
 * Clothing Damage: Conrad and Wolfram humiliate a group of thieves by shredding their clothes.
 * Crossdresser: Yozak regularly. Wolfram at least twice (not counting his sleepwear), and Yuuri at least three times. There's a Ms. Shinmakoku crossdressing beauty pageant in the video game, in which every one of the main charaters is forced to participate.
 * The Crossdressing Pageant is crossed-over into the series via OVA. Wolfram's skirt is very short.
 * Cultural Cross-Reference
 * Cuteness Proximity: Shori towards El.
 * Dark Is Not Evil: It applies to most of the Demon Kingdom. There are good people and bad people, but most of the "dark" characters are good and want to do the right thing.
 * David Versus Goliath
 * Dem Bones: Basic Mazoku minion is a winged skeleton.
 * Diagonal Cut
 * Disappeared Dad: All three of Cheri's sons have different fathers, and none of them are in the picture. Conrad's father in particular is explicitly mentioned to be dead.
 * Disney Death:.
 * Dramatic Wind
 * Drill Sergeant Nasty: While Gisela (whose nickname is "Sergeant") who is normally very nice, but can easily get angry.
 * Elemental Powers: Among the main cast: Yuuri is water, Wolfram is fire, Gwendal is earth and Gunter is air. Other characters are seen using the same powers.
 * Emotional Maturity Is Physical Maturity
 * Everybody Is Single: Except for the minor-character married couple with a kid. And technically Wolfram and Yuuri, but...
 * Every Car Is a Pinto: Conrad stabs the remote-control device that was driving a truck. Without any controls, it veered of the cliff and exploded.
 * Eyes of Gold: Saralegui.
 * Evil Laugh: Stuffel's is an evil laugh when he is forming his eeevil plots...
 * The Exile: Gegenhuber.
 * Eye Beams: Courtesy of King Bob.
 * Eyedscreen
 * Eyepatch of Power: Gegenhuber wears one of these.
 * Face Palm: When Yuuri's klutziness and social faux pas become too much even for Conrad...
 * Faceless Goons
 * Facial Markings: Genesus and Alazon.
 * Fan Service: Yuuri's special royal underwear. Plus much of the rest of the show.
 * Fantastic Racism: A core element of the story is the hatred between Mazoku and humans and Yuuri's attempts as Maoh to overcome it.
 * Fantasy Counterpart Culture
 * Fish Out of Water
 * Five-Man Band: Yuuri, Conrad, Wolfram, Gwendal and Gunter (although what roles the latter 3 fill is up for debate.)
 * Gunter makes a really ditzy Smart Guy, and Gwendal makes an uncommonly brilliant Big Guy. So Wolfram is apparently The Chick.
 * Can also be seen as Three Plus Two, with Yuri, Conrad and Wolfram sometimes breaking off (usually on the smaller adventures) and making a Power Trio while Gwendal and Gunter stay at the castle.
 * Floating Advice Reminder: Miko Shibuya often gives Yuuri silly advice using this trope.
 * Flower Motifs
 * Fluffy Tamer: Ryan
 * The Fool: Yuuri.
 * Foreshadowing: Jose and Conrart's scripture recitals about the sun and the moon while admiring Julia and Christine's souls.
 * Not to mention that they pretty much end up shoving it down your throat that, even though they tried to make it subtle.
 * Fourth Date Marriage: Subverted. Shouma proposed to Jennifer after five dates, but they only tied the knot half a year later, which means they had at least six months of experience under their belts already. Still on the shorter end of the courtship spectrum, but not nearly as unreasonable as this trope's usual fare. And they've been Happily Married ever since, with two sons to show for it.
 * Gadgeteer Genius: Annisina.
 * Glowing Eyes of Doom:, when giving someone a 'hint'.
 * Good Eyes, Evil Eyes: "Evil" characters have tiny pupils. "Good" characters have large pupils.
 * Gotta Catch Them All: The Forbidden Boxes
 * Grand Theft Me
 * Groin Attack: Yuuri, by his mother.
 * Hair Colors
 * Half-Human Hybrid: Mazoku/human halfbreeds are hated by humans and looked down upon by Mazoku. Entire villages exist with the sole purpose of keeping the halfbreeds away from everyone else.
 * Handicapped Badass: Gegenhuber.
 * Hate Plague: One episode featured a cursed miasma that makes a person unable to trust anyone.
 * Have I Mentioned I Am Heterosexual Today?: Yuuri would have you know he likes girls, thank you very much.
 * Heart Trauma:, in a way. While it doesn't affect his personality, the fact that he is counts as a drastic change.
 * Heir Club for Men: Shimaron's law stats that women can't inherit property. This plays a big role in the plotline involving Caloria.
 * Heroic Sacrifice
 * Heterosexual Life Partners: Conrad and Josak, though the "heterosexual" part is open to interpretation.
 * Hey, It's That Voice!: Why hello, Yuuri, aren't you also Cloud, Fakir, Suzaku, and Kanda? Hello, Conrad, aren't you Sephiroth, Griffith, Naraku, and Jounouchi? And is that Kakashi, Yuki, and Hatori I hear, Gunter? Hey, I hear Takahiro Sakurai, Toshiyuki Morikawa, and Kazuhiko Inoue. What the heck? Gwendal (Akio Ohtsuka) is SNAAAAAAAAAAAAAAAAAAAAAAAAAKE!!!
 * For English, Oh, hello, aren't you the guy with the same name as the main character who's in way too many animes as well?
 * As for Japanese Wolfram (voiced by Mitsugi Saiga), hey there Shindou! Same to you Elk . With English, where is your Prodigious laptop? Or the Twilight Bracelet?
 * Come the third season, Saralegui was a major example of this too. Oh hey Kaworu, Gaara, Judeau, Chrono, Break and a million others played by Akira Ishida. Hell, one of Sara's first lines in the first OVA were a direct reference to Kaworu's first lines in Evangelion.
 * Hidden Eyes: Yuuri does this when he's about to go into Maoh-mode.
 * Hot Shounen Mom: Cecilie (AKA Cheri) is a clear example of this trope. She is absurdly hot and dresses accordingly, plus she is quite flirty and often hits on Yuuri much to Wolfram's annoyance.
 * Also, Miko (AKA Jennifer), while nowhere near as obviously hot as Cheri, is still very pretty.
 * Hot Springs Episode: In the OVA.
 * A House Divided: Episode 65.
 * Hypnotic Eyes:  has these.
 * I Am Who?: You are the Maoh!
 * I Kiss Your Hand: Conrad employs this when he first meets Julia. Smooth!
 * Iconic Item: Julia's pendant.
 * If I Can't Have You: Wolfram, season one, episode fifty-two.

"Cheri: "I came all the way here just to show him some leg.""
 * "I Know You're in There Somewhere" Fight: Conrad tries to avoid this, but Yuuri is too lost in his angst to pay attention.
 * Implausible Fencing Powers: Just about everyone. Most surprisingly,.
 * Averted in Yuuri, who has no idea how to fight and survived those sword fights he was forced into through sheer dumb luck. He shows moderate improvement throughout the series, as he's shown to be training with Conrad regularly.
 * Innocent Innuendo: Wolfram awakens on a ship to hear Yuuri and Conrad having a rather sexual exchange of words. Turns out Yuuri was just getting his contact lenses put in.
 * In the Hood: Generally villains employ this trope, though Conrad and Wolfram have been known to as well.
 * Instant Messenger Pigeon: Or in this case, doves.
 * Interspecies Romance: Demons and Humans
 * Just Friends: Something Wolfram refuses to accept this from Yuuri.
 * Kissing Under the Influence: In the OVA, when
 * Knight in Sour Armor: Adelbert von Grantz
 * Kryptonite Factor: Mazoku are generally unable to use their magic and experience great pain when in the presence of Houseki. A glowing rock.
 * Kubrick Stare: King Belar often uses this stare so that you know he's EVIL.
 * Limited Wardrobe: Justified in that it's their official uniforms, slightly averted when they have to disguise themselves.
 * Averted completely by Wolfram, who is shown to have several other outfits. In the manga, he wears his uniform less than half the time.
 * Literal Cliff Hanger
 * Lost Technology:
 * Luminescent Blush
 * Magic Music: Yuuri's magic flute.
 * Maligned Mixed Marriage: Marriages between humans and the Mazoku certainly count, given all the problems that befall them and their children.
 * Mangst: Adelbert and Conrad and their periodical Mangst sessions where they sit around Mangsting about, who else,.
 * Manipulative Bastard:
 * Marshmallow Hell: Cheri does this to Yuuri, and occasionally to Wolfram. Everyone else is just too tall.
 * Mayfly-December Romance: Yuuri is fifteen, his fiance's eighty-two. Addressed through Cheri and Don Hiri and ignored by Hube and Nikola.
 * The Medic: Gisela and Julia
 * Medieval European Fantasy
 * Medieval Stasis: The Demon Kingdom (and the rest of the world) barely changes at all over 4000 years.
 * Meido: The three maids in Blood Pledge Castle. Yuuri once, and Yozak, of course.
 * Memento MacGuffin: Yuuri's necklace.
 * Mentor Ship: Conrad and Yuuri are actually the most popular ship in Japan. Wolfram beat Conrad out in America, probably a case of Values Dissonance.
 * The Messiah: Yuuri and Julia
 * Mind Control Eyes
 * Missing Mom: Averted with.
 * Played straight with Greta's mother.
 * Mistaken for Cheating: Wolfram is ALWAYS accusing Yuuri of cheating, and Yuuri never is.
 * Mistaken for Gay: Yuuri has given up on figuring out what everyone thinks his relationship with Wolfram exactly is by the third volume.
 * Modesty Towel: Cheri wears one on her first encounter with Yuuri in the baths.
 * Mooks
 * Ms. Fanservice:

""If it's about Gwen, there's no way Gwen hates you, Yuuri. Because he loves small, cute things.""
 * Named After Somebody Famous: Gwendal and Anissina, named after figure skating pair Gwendal Peizerat and Marina Anissina. Also the ten nobles, whose family names were all taken from famous figures in literature/drama.
 * Nerd Glasses: Murata and Shouri.
 * Neuro Vault: Or rather, Body Vault.
 * Never Found the Body: All they found was the arm and then they kept it, for a disturbingly long time (it wasn't decaying).
 * Noblewoman's Laugh
 * Not What It Looks Like: Yuuri and Wolfram quite a bit in-story. Conrad and Yozak get a few accidently compromising panels, too.
 * Conrad's pinning him to the wall because he's angry, of course.
 * Off-Model
 * Official Couple: The entire country believes Yuuri and Wolfram are dating, no matter how much Yuuri dislikes this.
 * The Ojou: Cheri, Annisina, possibly Gisela.
 * Older Than They Look: Just about the all Mazoku/Demon Tribe could actually fall under this as they are found to age differently than humans.
 * Especially Cheri, who looks younger than her oldest son.
 * One True Sequence: Barely averted, as the box on Earth can't be found by Big Shimaron, and therefore results in one box not fought over.
 * Open-Minded Parent:.
 * Or Was It a Dream?
 * Oracular Urchin: Ulrike
 * Orgasmic Combat: Elizabeth makes quite a lot of noise while she fights Wolfram. Close your eyes and listen to the fight scene; it's very entertaining.
 * Our Demons Are Different: And how. The demons in the other world are quite possibly some of the least demonic looking ones ever made.
 * They're also German.
 * Paper-Thin Disguise: Apparently no one knows who Yuuri is if they can't see his black hair and black eyes, even though everything else looks the same. Justified in that anyone who knows him recognizes him, and all anyone who doesn't know him knows is that he has black hair and black eyes.
 * Parent Ex Machina: Played with pretty much literally in a later episode where
 * Pet the Dog: Gwendal has a huge weakness for all things cute, and he spends his spare time knitting dolls.
 * Used in-series to make him less intimidating to Yuuri.
 * Used in-series to make him less intimidating to Yuuri.


 * Playing Pictionary: Nobody can ever figure out what Gwendal's knitted animals are supposed to be.
 * Please Wake Up: Greta (and Yuuri) when
 * In the S3 finale, Wolfram and Greta while.
 * Plot Armor: There's never a reason to worry when Yuuri gets kidnapped. He's always safe really.
 * Portal Pool: Naturally.
 * Portmanteau Couple Name: While Yuuri and Wolfram aren't a 'couple', per se, Greta still names her mini-Bearbee 'Yuuram'.
 * Post-Kiss Catatonia: Subverted slightly in the sense that the kiss actually made completely pass out.
 * Power Makes Your Hair Grow: Yuuri.
 * The Power of Love
 * Powered by a Forsaken Child: In the OVA, a Pink Bear Bee must be sacrificed in order to stop the dragons from destroying the world.
 * Present Absence: The Original King/Shinou
 * Promotion to Opening Titles: Jose, Bob, Shouma, Shori, Hube, Julia, and Don Hiri are put into S2's titles, Darcauscos, the Maids, Greta, Shinou, and Bearbees are put into S3's.
 * Punny Name: Shibuya Yuuri Harajuku Furi
 * Quivering Eyes
 * Rags to Royalty: Every day student Yuuri becomes King of a nation.
 * Ready for Lovemaking: Wolfram tries this at one point (and fails miserably). In the anime this scene is replaced with Yuuri waking up to find Wolfram in bed with him.
 * Really Seven Hundred Years Old: Shrine Maiden Ulrike is 800 but looks like a young girl. (Ondine, introduced later in the anime, was the maiden before Ulrike and looks, if anything, even younger.)
 * possibly counts. He really is about 16, but
 * Real Men Wear Pink: Gwendal's knitting, Yozak's crossdressing and Wolfram's strange choice of sleepwear (it's implied that the latter may be a deliberate attempt to get Yuuri to like him by making himself appear more feminine).
 * Red Shirt: Various soldiers assigned to guard Yuuri get killed as a sign that he is in danger. Attacked by ninjas, the guard get killed first. Attacked by a killer sand panda, the soldiers fall into the trap before them.
 * Redshirt Army
 * Reincarnation:  and
 * Reincarnation Romance: Because of the above mentioned reincarnation, there are hints that a possible (one-sided?) reincarnation romance could develop between
 * Sage and Shinou.
 * Ridiculously Cute Critter: The Bearbees. Nogisu!
 * Kevin's sandpanda too, once it's no longer threatening to kill everyone...
 * Ronin: Geigen Huber, Gwendal's cousin. Even more, Adalbert, who is completely comfortable with his role as an free-wheeling post-racial swordsman, and while he slides increasingly toward idealism and believing in The Messiah, never gives up his independence.
 * Royals Who Actually Do Something
 * Running Gag: Anissina's forcing Gwendal or Gunter (or both) to assist in her various demon-magic-based technology experiments.
 * Also Yuuri standing up to bullies in order to rescue a victim only for said victum to run away and leave Yuuri to be beaten up.
 * Runaway Bride: Nikola
 * Save Both Worlds: In the end of Season 2, when Soushu is leaking all over into Earth and not even everyone in Shin Makoku can keep the massive armies in check. Granted, they don't actually know Earth is in danger.
 * Screaming Warrior
 * Sealed Evil in a Can: Soushu
 * Shirtless Scene: Yuuri gets one in the second episode
 * Shoot Your Mate: Or Stab Your Mate, as the case may be.
 * Shoulders of Doom:  armor has huge shoulder pads, and
 * Single-Episode Handicap: Yuuri sprains his ankle for a storyline, but is perfectly fine by the end.
 * Single-Stroke Battle
 * Skyward Scream: A couple, but most memorable was Wolfram's AAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHH YYUUURRRIIIIIIIII after they found Conrad's arm and
 * Sleep Learning: Conrad uses this to learn Japanese.
 * Sliding Scale of Silliness Versus Seriousness: It starts of as lighthearted a comedy as an action-type could ever be. By the third season, it's much more serious. Links in to major Character Development.
 * Smug Snake: King Lanzhil from season three thinks that he's completely in control. You can just tell what's going through his mind. He thinks that Janus and the White Crows are following his bidding. Small Shimaron and their King, Saralegui are far too weak and incompetent to do anything against him. He's going to conquer the world and wipe those vile Mazoku along with their leader the Maoh off the map! Needless to say, he winds up getting used and/or beaten by all three of them. Repeatedly.
 * Spell My Name with an "S": Yuri or Yuuri? Celi or Cheri? Dorcas or Darcauscos? Nikola or Nicola?
 * Stable Time Loop: Yuuri going back in time and meeting Julia makes it possible for him to exist, because it makes her accept her fate.
 * Stupid Sexy Flanders: With all the Yaoi Guys in this series it's no surprise Yuuri (and the audience) have a few of these moments. Especially regarding Wolfram's sleep wear.
 * Succession Crisis: Big Shimaron is set to face one at the end of the third season. Saralegui plans to take full advantage of this, aiming to take the throne and unite it with his own Small Shimaron.
 * Super-Powered Evil Side: The Maoh, though not actually evil, is more than willing to beat the stuffing out of anyone who pisses him off
 * Swirly Energy Thingy
 * Sword Fight
 * Sword Lines
 * Take My Hand: Complete with cheesy, "Then we'll fall together!" line.
 * Take Our Word for It: Usually happens when there is violence or one character is injured. Particularly noticeable in episode 27.
 * There Is Only One Bed: Subverted: Wolfram has his own room and bed, but sleeps in Yuuri's anyway, because "I'm your fiancé!"
 * Threshold Guardians
 * Time Travel: Yuuri gets sent back in time while coincidentally under a disguise to watch the events in Shin Makoku 20 years previous.
 * Too Spicy for Yog-Sothoth: Yuuri is just too cute to be eaten by the dragon.
 * Tracking Device: Ulrike can find Yuuri's location on a super special soul-map thingie.
 * Translation Convention: It is made clear in the first episode that the characters in the other world are not speaking Japanese, but Yuuri hears it as such, and so we the viewers do as well. This goes double for the English dub, where Yuuri keeps remarking (in English) on the quality of everyone's Japanese in a foreign land.
 * Translator Microbes: Subverted. Aldebert has to unlock the ability to speak the Mazoku language from Yuuri's spirit.
 * Transparent Closet: Yuuri is totally, completely heterosexual. Even though no one in this world knows what that means. He's not just in a transparent closet, he toted that closet over from another dimension. If he really is closeted. There is still room for doubt.
 * Trapped in Another World: and, occasionally, trapped in the original one, too.
 * Triang Relations: Type 3. Sara wants Yuuri (although possibly only ), Wolfram wants Yuuri, and Yuuri wants... nobody.
 * Tsundere: Wolfram and Also Gisela, who can go from sweetness and sunshine to Drill Sergeant Nasty (and back) in the blink of an eye.
 * Unlucky Childhood Friend: Elizabeth.
 * Unwanted Harem: Yuuri has an all male one - that's why he doesn't want it.
 * Villainous Breakdown: King Belar, after the Villain Decay.
 * Viva Las Vegas
 * The Von Trope Family: Subverted, as it has nothing to do with personality, and is actually used correctly to mark nobility in the Germanic-based fantasy realm of Shin Makoku.
 * Wacky Marriage Proposal: Er, right. Watch who you slap, you never know what might happen.
 * Warring Natures: Demons vs. Humans. Conrad and Josak choose to fight for the Demons.
 * We Are as Mayflies: The mazoku live much, much longer than humans.
 * What Do You Mean Its Not Symbolic:  Conrad's arm, Gwendal's eye, Wolfram's heart, and Yuuri's soul.
 * Whip It Good
 * The Worf Effect: Wolfram is generally the unlucky victim of this trope.
 * Xanatos Roulette:
 * Yaoi Fangirl: A trio of castle maids spend practically all their screentime taking notes, placing bets, and calculating the odds of Yuuri's various romantic prospects.
 * Yaoi Guys: Yuuri is really, really apathetic and absolutely chaste with Wolfram. Wolfram, on the other hand, is head over heels for Yuuri.
 * Year Inside, Hour Outside: Time between the two worlds gets closer to flowing at the same rate as the anime progresses, however.
 * Younger Than They Look: Conrad and Yozak are actually an example of this within Shin Makoku, although at their current levels the face is probably not a major factor in guessing age in that culture. When Conrad was thirty he probably looked thirteen, but had spent enough time around humans that he was more mature than most Mazoku sixty-year-olds. Which explains pretty much everything about him, except that weird need he has to have a specific person to be fixated on at all times.
 * It is theorized that some corollary to the Mazoku slow development and longevity gene is that they learn really, really slowly. Not that they're stupid; they can understand things well enough, they just don't form memory, especially procedural memory, without a lot more repetitions than it takes humans.
 * This helps explain things like Wolfram, and also sheds light on Conrad: his particular genetic mix left him a prodigy among Mazoku for his learning speed (hence his scorn of the other students in the flashback scene where Gunter kicks his ass) and with a ridiculous amount of time to practice compared to humans, since by his age even his fellow martial geniuses are normally bedridden.
 * Hube and Nikola's offspring grows a bit fast even compared to human infants. If he turns out to have a max lifespan of thirty years, it will mega-suck.
 * Yuri Lowenthal: In the dub. Guess who he voiced?
 * Lowenthal is the English voice actor, so it may very well be The Danza in reverse.)
