    Demon Lords 
The Demon Lords are the leader of the Fallen. They were once one being but were shattered into multiple aspects and sealed away.
  • Pieces of God: They were originally one being but were split and sealed by God.

Demon Lord of the Mind, Enkvaros

The first Demon Lord that revived. In Cross Reverie Diablo was the first player who defeated it solo and where he got the Demon Lord's Ring.

Demon Lord of the Soul, Krebskulm

Voiced by: Atsumi Tanezaki (Japanese), Madeleine Morris (English)
Yes, this is "the demon king" Krebskrum.
If she looks like this, and you're not Diablo, run.

The one the Fallen worships. In the game story of Cross Reverie, it is the strongest boss in the game.

  • Adorably Precocious Child: Despite being technically a newborn, she loves to strut around and act like she's all grown up. The main characters all go gaga over her, even Diablo.
  • Affectionate Nickname: The main characters call her Kemm, not just because they like her, but as an alias, so she's not immediately attacked and set off a panic in the town.
  • Alternate Identity Amnesia: Defied. She has full memory of her actions while in her berserker state.
  • Amnesiac Dissonance: Although she remembers who she is and what she's supposed to be doing, she doesn't remember why and therefore is easily convinced to give up on it, especially when baited with biscuits.
  • Armor-Piercing Attack: «Infinite Detonation» lets her attack her opponent even if they use abilities that should void attack.
  • Badass Adorable: This sweet, innocent, biscuit-munching child can blow holes in solid stone walls without even trying. She literally curbstomped Modinalam until he went One-Winged Angel, and even then gave him a hell of a fight.
  • The Berserker: When she's enraged, to the point of "awakening," she loses the ability to reason, and attacks indiscriminately, unable to tell friend from foe.
  • Big Eater: Place anything remotely resembling "biscuits" in front of her and she will eat a lot of it.
  • Break the Cutie: Saddler and his motley crew of sycophants certainly tried.
  • Breath Weapon: In her "Demon King" mode, she can fire a breath attack of the pure darkness element. Diablo suspects that even he wouldn't survive a direct hit.
  • Cheerful Child: She's actually a very sweet and happy child. As long as she isn't directly provoked, she's perfectly fine with "live and let live," although she occasionally voices the desire to burn up people en masse when she gets impatient. The fans note that she really takes after Diablo in this regard.
  • Children Are Innocent: She is an accurate representation of an elementary school child.
  • Cute Little Fangs: Diablo notes that she has rather sharp fangs when she playfully nibbles on him in volume 3. Although they hurt a little bit, they don't do any real harm.
  • Cute Monster Girl: After being awoken, she briefly appears monstrous before reverting to a cute little girl that looks no more than about six. Apart from her horns and tail, she looks like a normal person.
  • The Cutie: Everybody who meets her and isn't an Omnicidal Maniac or otherwise completely batshit crazy and violent finds her absolutely adorable.
  • Dark Is Not Evil: Her attribute is darkness, as expected of a demonic being, yet she's wholly innocent, cheerful, gentle and kind, as long as she's not deliberately provoked.
  • Expressive Hair: In the anime, when she's especially happy, her twintails flap in a very wing-like fashion. Which only tends to make her look even cuter.
  • Hair of Gold, Heart of Gold: She's blonde and is both sweet and innocent.
  • Has Two Mommies: Despite Rem being the one who technically gave birth to her, she's latched on to Shera. Nobody seems to mind.
  • Healing Hands: She has the ability to instantly heal the wounds of the Fallen with a wave of her hand.
  • Horned Humanoid: She has goat-like horns growing out of her head.
  • Hulking Out: When she's forced into battle, predominantly as a result of harm to her loved ones, she transforms into a being at least three times Diablo's size, and gets a massive boost in her physical strength and ability to cause damage. Unfortunately, she loses her ability to reason, as well as to separate friend from foe in the process.
  • Improbable Weapon User: Even in her berserker mode, she's not mindless. While it's true that she can't tell friend from foe, she does learn from her actions. After seeing Diablo dodge her arm swings, reflect her magical attacks, and block her Breath Weapon, she starts throwing coffins at him. When she sees the last actually prove effective, she goes and picks up the entire northern rampart and throws it at him.
  • Involuntary Shapeshifting: She has no control over changing forms.
  • Killer Rabbit: She's an adorable little child who wants to eat all the biscuits in the world. But she's also the most powerful being who could lay waste to the world if she wanted to.
  • Little Bit Beastly: If not for her horns and lizard tail, she could very easily pass for an elf toddler.
  • Made a Slave: This time, it's done willingly. Being presented with three options, none of them good, she chooses, nay demands to be made Diablo's slave so that she can continue to live happily in Faltra and eat biscuits.
  • Mix-and-Match Critter: She has features of all three protagonists. She has horns, eyebrows and public attitude similar to Diablo's. She has blonde hair and pointed ears like Shera. She has animal features like fangs, claws, and a tail similar to Rem, though reptilian rather than feline, and it all makes her absolutely adorable.
  • Monstrous Humanoid: Her battle form is at least three meters tall and comprised mostly of black armor. She has five glowing eyes, twisted horns instead of hair and otherwise looks like a woman wearing full armor. The 'real' Krum seems to be inside the middle of the torso, however, which means one arm and the head can break without seeming to actually hurt her.
  • Morton's Fork: After her rampage, due to Sadraa's despicable acts, Sylvie is forced to give her two options, surrender herself up for public execution or become the enemy of the world and be hunted down. Fortunately, Diablo is able to come up with a third option.
  • Nigh Invulnerable: When in her full Demon King form, an attack that turned the entire graveyard, and a portion of the northern rampart, into a crater only broke one arm. It was only Shera's Power of Friendship that managed to stop her rampage.
  • No Item Use for You: Healing potions and magics are completely useless for her. Only her own mana can heal her.
  • Our Phlebotinum Child: Due to the nature of her birth she is technically the child of Diablo and Rem, with Rem harboring her soul and being pregnant with her, while Diablo poured his mana into Rem to separate Klem from her body. While Shera is effectively the surrogate mother who Klem is most attached to.
  • Phlebotinum Battery: She is one. Almost to the point of Perpetual-Motion Monster. She generates mana inherently and can distribute it to others, especially as a result of extreme arousal, as Diablo learns first hand after Shera accidentally unlocked this ability.
  • Pointy Ears: Rem and Shera are able to pass her off as an elf because of her pointed ears.
  • Promoted to Love Interest: She willingly demands to join Diablo's slave harem at the end of volume 3.
  • Purple Eyes: To highlight her supernatural origins, she's got purple eyes.
  • Rapunzel Hair: Her golden-blonde hair reaches her knees.
  • Rage Against the Heavens: She resents "god" for locking her spirit away many generations ago, and bears no malice against Rem for resenting her because of the suffering being sealed inside her and her ancestors brought.
  • Sacred First Kiss: She gives hers to Diablo as part of the Master-slave contract into which she willingly enters.
  • Sealed Inside a Person-Shaped Can: Her soul was sealed inside of Rem, which was previously sealed in Rem's mother.
  • Shapeshifter Baggage: She goes from being three times Diablo's size to the size of an elementary school child, and back again, gaining and losing the proportionate amount of mass, without explanation.
  • She Is the King: She is the Demon Lord for that matter, which is a masculine tittle.
  • Sleepmode Size: When she first appears, she's three times Diablo's size, but then shrinks down to the size of a small child.
  • Spell My Name with an "S": Is is Krebskrem or Krebskrum? The translator officially apologized and says it's supposed to be Krebskrum.
  • Superpowered Evil Side: Do Not Harm Her Loved Ones if you value your life. Threatening the people who she loves will drag her out of her Sleepmode Size and into an Unstoppable Rage.
  • Sweet Tooth: Although she likes coffee, she will happily praise any sweet snack-like treat she's given.
  • Tastes Like Friendship: Shera was able to formalize a peace treaty with her by feeding her biscuits. She later does the same to Sylvie, sharing one of her biscuits with the guild leader because the guild leader offered to aid her any way she could.
  • Token Mini-Moe: She's technically a newborn, making her the youngest girl in the cast, and she's adorable on both sides of the fourth wall.
  • Trademark Favorite Food: Biscuits, jam biscuits, nut biscuits, all the biscuits of the world!
  • Traumatic Superpower Awakening: Her demon lord powers awaken after witnessing Rem getting stabbed by Saddler. Though Rem tried to make her promise not to hurt anyone, she ends up killing him during her awakening.
  • Unskilled, but Strong: As to be expected, her "fighting style" is the random lashing out that would come from a small child, but the level of firepower, both figurative and literal, that she brings to bear is more than enough to level an army or even Diablo, should an attack actually manage to connect.
  • Unstoppable Rage: Literally. Once she's rightfully enraged, even she can't stop her actions.
  • Verbal Tic: She ends her sentences with "-noda" or some variant in the original Japanese release.
  • Wise Beyond Her Years: While she doesn't have much in the way of her original memories, she does still have access to centuries' worth of wisdom to draw from.
  • You Wouldn't Like Me When I'm Angry: She's a very sweet, understanding, well-behaved, and cheerful child, and it's very difficult to upset her. Should you actually succeed, especially by harming her loved ones, she will ignore any promises she made about sparing you and go into The Berserker Superpowered Evil Side which will not only annihilate you, but the entire army that came with you, and maybe the entire city behind you.

Demon Lord of the Heart, Cardia

The Demon Lord sealed in the Kingdom of Greenwood.

  • Demonic Possession: Its consciousness took control of Raphlesia's body.
  • Killed Offscreen: Assimilated by Mondinalam, or killed. Either way, it's not gone and not coming back.
  • Leaking Can of Evil: Despite being sealed away, it still had a powerful influence on the area nearby, even possessing Raphlesia.
  • Master of Illusion: When possessing a host, it can make illusionary copies of itself to make any enemies waste their attacks.
  • Sealed Evil in a Can: Sealed inside a gem by the Kingdom of Greenwood... until Mondinalam's followers show up.

Demon Lord of Insanity, Modinalam

A Demon Lord that is absorbing other Demon Lords. In Cross Reverie he was a Golden Week event boss.

  • Assimilation Plot: He wants to combine with the other fragments to become the «Originator Demon Lord» once again to destroy the races.
  • Hoist by His Own Petard: At least thrice. Diablo reflects his ultimate attack back at him, he tries to blow up Diablo but only winds up harming himself, and he consumes his own army for magic power just to have all that magic power blow up in his face.
  • Irrational Hatred: While Krebscrum's reason for protecting the six races is rather silly, eating biscuits, at least she has a reason. Modinalam has no reason whatsoever for attacking and trying to exterminate the six races at all.
  • Revive Kills Zombie: He's terrified of Elixirs, the ultimate healing potion, because they can kill him.

    Edelgard faction 

This great Gregore saw a cat Ee, Ei, Ee Ei, Oh!
A lizard-like Fallen.
  • An Arm and a Leg: Once Diablo gets involved and starts blasting him with magic, Gregore literally loses an arm, a leg, and his tail before he realizes just how outclassed he is. Unfortunately for him, this is far, far too late as Diablo stated from the beginning that pleading for mercy wasn't an option. Averted in the anime.
  • Bare-Fisted Monk: When not using magic, he attacks with his bare hands.
  • Cassandra Truth: Inverted. Diablo tells him before their "fight" that Edelgard has already been driven away and mentioned Edelgard by name. He refuses to believe it, calling it "an obvious lie" despite the fact that if Diablo was lying, there's no way he should have known Edelgard's name.
  • Elemental Powers: Uses Chemical Elemental magic.
  • Fantastic Racism: Racist against the Demon race, and humans.
  • Fate Worse than Death: In the anime, instead of being slowly killed by Diablo, he is sent to a void dimension for all eternity. All things considered, death would have been more merciful.
  • Jack-of-All-Stats: How Diablo describes him. "Punching Magicians" are seen as Jacks of all stats, master of none.
  • Killed Off for Real: By Diablo.
  • Kung-Fu Wizard: A «Punching Magician» that uses both magic and fists.
  • Laser-Guided Karma: He made a sport out of tormenting humans into despair by holding back and giving them false hope then crushing them as they begged for their lives. Diablo "experiments" to learn the limits of his magic by torturing him to death, as he's pleading for his life.
  • Lizard Folk: He has the appearance of an overgrown bipedal lizard.
  • Mugging the Monster: When he challenged Diablo, he had absolutely no idea what kind of trouble he was getting himself into. By the time he realized it, there was no other option for him than to wait until Diablo got bored and killed him off.
  • No Body Left Behind: Diablo kills him by sucking him up into an Unrealistic Black Hole.
  • Non-Mammalian Hair: He is depicted as a hairy lizard in the anime version.
  • Punched Across the Room: Diablo blasts him away with an air bullet to protect Emil, Rem, and Celestine.
  • Reptiles Are Abhorrent: Both physically and morally repugnant.
  • Spared By Adaptation: Well...he was spared from death but in this case that might have been better considering his fate in the anime.
  • Tears of Fear: The guy is basically crying at the end for Diablo to not kill him. It doesn't work. While it's satisfying in the light novel and manga, it's actually a little unsettling in the Anime as the guy has no chance to fight back, is basically rendered helpless, is pathetically begging for his life, and Diablo makes him suffer first before sending him to another dimension. While he did have it coming you can't help feel for him a little if only because no one should have to suffer and beg for their life before they die.
  • They Just Don't Get It: He sees one of his spells bounce off Diabo and hit himself, so he... uses another.
  • Third-Person Person: He mostly refers to himself as "this Gregore."
  • Villains Want Mercy: When he finally realizes a fight with Diablo is unwinnable, he begins pleading for his life. At this point, Diablo reminds him of two things. 1.) Diablo promised that he would show no mercy. 2.) Gregore didn't show any mercy to his victims when they were begging for their lives, and Gregore had killed a lot of innocent people in Faltra alone.


Voiced by: Emiri Katou (Japanese), Kristi Rothrock (English)
Surprisingly, she's one of the more reasonable Fallen.

A Dragon Knight Fallen.

  • Adaptational Curves: She is rather flat chested in the manga and in the illustrations of the light novels, while in the anime she has decent sized Boobs of Steel.
  • Ambiguously Brown: She has dark skin.
  • Bad Guys Do the Dirty Work: Although "bad" might be a bit harsh, she kills six bandits that planned to attack and abduct Rem and Shera while they were bathing together.
  • Cast From HP: Her skill aptly named "Sacrificial Charge" uses up 15% of her hp upon activation.
  • Clothing Damage: When hit by Diablo's white nova attack, Edelgard ended up losing most of her clothes and was even left topless.
  • Dark Action Girl: She is first genuine Action Girl to be introduced in the series that started out as an antagonist.
  • Dark-Skinned Blond: She has silver hair and dark skin.
  • Dragon Rider: She's introduced riding up on some kind of reptilian mount.
  • Heel–Face Revolving Door: She goes from being the enemy of Faltra to one of its strongest allies after meeting Rem and being present at Klem's "birth." Even being willing to fight her own race to protect the people within. She briefly sides with the Fallen again, when she thinks what's best for Klem is awakening her Superpowered Evil Side, but when she finds out she's wrong, she joins the population of Faltra, willingly, and submits entirely to Diablo's mercy.
  • Hellish Pupils: Diablo notes that her pupils are slits, like a reptile's.
  • Jousting Lance: Diablo lampshades that she wields one due to being the self-proclaimed strongest spear-user among the Fallen.
  • Know When to Fold 'Em: After taking a direct hit from Diablo's ultimate magic, she wisely withdraws when Diablo gives her the chance.
  • Lizard Folk: She has numerous reptilian features.
  • Made of Iron: She takes a direct hit from a level 130 spell, and is still standing with only minor clothing damage. Diablo is impressed.
  • Meganekko: Part of her disguise involves a set of magical glasses that hide her reptilian eye slits.
  • Meido: To hide the fact that she's a Fallen, Mei disguises her as a bespectacled maid, and she acts like one, in service of "Maou", aka Krebskulm.
    • Volume 8 in the light novels, she ends up in a Naked Apron with her panties and shorts on while working and patrons think she's cosplaying as a Fallen. She admits it's because she got caught in a strong rain one day and her disguise was ruined revealing that she's a Fallen, but no one freaked out or said anything, so she went along with it.
  • Mystical White Hair: She has silver hair.
  • Noble Demon: She's a Fallen and is utterly ruthless in combat. Still, she's honest, noble, brave, loyal, and prefers the peaceful solution whenever possible, unlike most of the other Fallen shown that act like omnicidal maniacs, and that's the "moderate" faction.
  • Rapunzel Hair: In the light novel, Diablo notes that her hair reaches her waist.
  • Supernatural Gold Eyes: To highlight that she's a Fallen, she has golden eyes.
  • Take a Third Option: Rather than fight Diablo and abduct Rem, try to kill her, or give up on resurrecting Demon King Krebskulm, she proposes a ritual that allows Krebskulm's soul to leave Rem's body without killing her. All parties involved are happy to go along with the idea.
  • This Cannot Be!: Twice in the same fight. First when Diablo tanks her Sacrificial Charge skill, and again when Diablo unleashes White Nova on her.
  • Undying Loyalty: To Krebskulm. Her only purpose in life is serving Krebskulm. While her primary goal isn't the extermination of the Six Races, if that's what it takes to make Krebskrum happy, so be it.
    • In Volume 8 Krebskulm asks her if Fallen can have children, to which she admits that they can and the process is exactly the same as what the Six Races do to have children. Krum asks her if she would consider having children and she says only if Krebskulm would order it. Krum implies that she would only ask Diablo to do that to her.
  • Villainous Friendship: She's genuinely very good friends with Alicia. So much so, that she will happily put her life on the line for the latter.
  • Villain Respect: Initially, she was dismissive of Diablo and only saw him as an obstacle to be moved. Then she tried fighting him. It didn't go well for her. Not only was her strongest physical attack tanked by Diablo, she barely survived his Ultimate Attack which wiped out her entire army. Later, while still loyal to Krebskrum, she now regards Diablo as a demon lord as well and even when not in his presence, calls him Diablo-Sama, or Lord Diablo in English, to other characters while making it clear that she wants to avoid confronting him openly at all costs.
  • You No Take Candle: She speaks in broken sentences. Averted for the English dub of the anime however, where she speaks in full sentences.

    Eulerex Faction 


The leader of the faction of Fallen that want to destroy the races under the leadership of the Demon Lord.


The leader of the Fallen that Diablo's party has to fight in Zirconia town.
  • Amazon Chaser: His preferred mate are women strong enough to actually challenge him.
  • And Now You Must Marry Me: To Lamnites, after he broke into her bath.
  • Awesome by Analysis: He realized Diablo's magic reflection ability by seeing it. Didn't do much to save him though.
  • Battle Harem: His wives all serve at his side in combat.
  • Bond Villain Stupidity: He could have annihilated Zirconia town with ease and given Diablo's party a hard fight, but he made two very careless mistakes. First, he breaks into Lamnite's bath, alone, and attacks her, fleeing when her knights showed up, giving her warning that the attack on the town was coming in the process. Second, he begins flaunting his wives and wedding rings in front of Diablo while there was a fight going on already.
  • Harem Seeker He's introduced with several wives, but is still scouting more.
  • Suicidal Overconfidence: True. He is powerful, but he thinks way, way too much of himself, and it made him careless when he antagonized Diablo.

    Vahl Faction 


The leader of the faction that just wants to destroy the races without planning.

How well does it match the trope?
