Characters / Demon Blade

A list of characters from Demon Blade.

Main Cast

Tsurugi Diablo

Tsurugi Diablo

The main character, a 13-year old bounty hunter and the son of a military advisor who had betrayed and killed the Feudal Overlord he was working for 12 years ago. Diablo's father was himself murdered four years before the events of the story.

Tsurugi Diablo displays examples of:

• Badass Cape: Wears his signature red cape throughout most of the comic. It serves a practical purpose too, as he often uses it to hide his tail among humans.
• Blood Upgrade: Making him bleed his own blood is arguably the fastest way to lose in a fight against him.
• Brains and Brawn: Diablo's got the brawn, Dr. Suno's got the brains.
• Combat Pragmatist: He'll do whatever it takes to win, up to and including feigning surrender.
• Glass Cannon: Ends fights quickly, but tends to take a while to recover after taking just one or two hits.
• Good Is Not Nice: Becomes this after he has something to protect.
• Half-Human Hybrid: Due to high tension between humans and demons, Diablo's father had to keep him a secret from the world, and in the present day, he has to conceal his demon traits when he goes out in public.
• Improbable Use of a Weapon: His sword is a rapier. However, he often creates an energy blade around it so he can slash with it.
• Limited Wardrobe: He stands out among the main cast in that he only has one outfit. He is homeless at the beginning of the story, so it's most likely the only outfit he owns. His cape also helps hide his tail, so he still wears it even after being taken in by the Suno family.
• Katanas Are Just Better: Variation: His sword changes shape depending on who holds it, and it's a rapier in Diablo's hands, but he usually creates a katana-shaped energy blade around it when he fights seriously.
• Meaningful Name: "Diablo" and "Tsurugi" mean "Devil" and "Sword" in Spanish and Japanese, respectively.
• Red Oni, Blue Oni: Diablo is a Red Oni, and has had both Dr. Suno and Dogma for Blue Oni.
• Shirtless Scene: Courtesy of Yara-ma-yha-who and much to Michiko's delight, Diablo takes off his soaked shirt to increase his mobility.
• Sir Swears-a-Lot: Most of the comic's profanity comes from Diablo, although rarely does he go further than "ass" and "damn".
• Sword Beam
• Small Name, Big Ego: At first.
• They Call Me MISTER Tibbs!: Insists that Dogma call him "Tsurugi the Great".
• Trademark Favorite Food: Kitsune udon; noodles with fried tofu on top.
• What the Hell, Hero?: Hinako calls Diablo out on his selfish reasons for wanting to fight Dios alone.

Dr. Suno Takamaru

Dr. Suno Takamaru

That loon who's always inventing crazy things, Dr. Suno also runs a clinic. However, he was also an officer for the Orochi Empire, and built many a Humongous Mecha for their use, a decision he deeply regrets. He opened his clinic to save as many lives as he could after indirectly claiming so many.

Dr. Suno Takamaru displays examples of:

• The Atoner
• Badass Longcoat: Of the lab-coat variety.
• Beehive Barrier: Silver Visage is equipped with one.
• Brains and Brawn: Dr. Suno's got the brains, Diablo's got the brawn.
• Heel–Face Turn: Before the events of story began. He worked for the Orochi Empire during the Chaos War, but had a change of heart after the Empire fell.
• Humongous Mecha: Doesn't pilot one himself, but has built many before.
• Leg Cannon: Silver Visage's main form of attack is a pair of plasma cannons that double as its legs.
• Let's Get Dangerous!: He isn't a fighter at heart, but if he's forced to, he can wreak some havoc with his Mini-Mecha.
• May–December Romance: He's 12 years older than his wife.
• Mini-Mecha: His personal mech is the smallest one he's built.
• Older Sidekick: About the closest thing to a sidekick that Diablo has.
• Red Oni, Blue Oni: One of the Blue Oni to Diablo's Red Oni.
• Renaissance Man: Currently a medical doctor, formerly a military engineer. Appears to have a strong interest in demon biology as well.
• Theme Naming: His family has a bird theme going on. "Taka" means "hawk", while his surname means "of the nest".

Suno Hinako

Suno Hinako

Dr. Suno's daughter, who first appears as a Damsel in Distress, but later turns out to be an Action Girl. Unfortunately, her training is incomplete, due to her teacher's murder several years ago. Her training partner was Jay von Schlag.

Suno Hinako displays examples of:

• Action Girl: Was trained by an old friend of her grandfather's in martial arts.
• Bare-Fisted Monk: Her fists alone can take down monsters several times her size.
• Betty and Veronica: The Veronica to Michiko's Betty.
• Combat Medic: Inverted; she's primarily a fighter, but being the daughter of the best doctor in town does give her enough medical knowledge to support her allies.
• Cute Bruiser: She's the youngest of the main cast (being a few months younger than Michiko), but easily the strongest physically.
• Empowered Badass Normal: Could hold her own against demons even without any magical powers. And then, while training with Jay, she learns to manipulate fire.
• First-Name Basis: After she is cured of her poison from Loki, Diablo starts to call her by her given name.
• Little Miss Badass: She's 12 years old at the beginning of the story. The only enemies who have defeated her so far are the ones who have caught her off guard.
• Muscles Are Meaningless: She lacks visible muscle definition, but she can easily block a punch from Yowie, who is easily at least three times her size.
• Playing with Fire: She learns pyrokinesis while training under Jay.
• Theme Naming: Her name follows two themes at once:
  • Continuing the bird theme mentioned in her father's example above, "hina" means "chick". However, this applies to the pronunciation only, as her name does not contain the kanji "hina".
  • Her name, spelled in Japanese, contains the kanji for "sun", while her two best friends, Michiko and Natsuki, have the kanji for "earth" and "moon" respectively in their names.
• Wise Beyond Their Years: Between herself, Michiko, and Natsuki, Hinako is the youngest, but arguably the most mature of the three.

Michiko Baki

Michiko Baki

Michiko is the daughter of a man who fought in the war, and is also Hinako's best friend. She makes few appearances in the beginning, but becomes more important after she's kidnapped by Vlad.

• Animal Motifs: The rabbit, as represented by her twintails and the fact that she's more dangerous than she looks, combined with her owning a pet uyagi, which resembles a rabbit.
• Badass Adorable: Once she Took a Level in Badass.
• Badass Normal: Lacks any magical abilities or special weapons, but after being trained by Diablo, she manages to fight toe-to-toe with demons anyway.
• Betty and Veronica: The Betty to Hinako's Veronica.
• Chekhov's Gunman: Appears to be a minor character at first, but soon after the raid on Yaibato's mansion, she joins the main cast.
• Combat Pragmatist: Seems to have rubbed off on her from Diablo, against inhuman enemies at least; she has no problem shoving her sword down Yara-ma-yha-who's throat. Then again, he did have Diablo cornered...
• Dual Wielding: Fights with a combination of... a fencing foil and a bamboo shinai.
• Expy: Her design is partly inspired by Hatsune Miku, who her mother is even named after.
• Gender-Blender Name: Sort of. Michiko's first name is pretty feminine, but many characters start out on a Last-Name Basis with her, even though Baki is a masculine name.
• Girlish Pigtails: Sports a pair of big, fluffy twintails, secured by black bows.
• Licked by the Dog: One of the few characters whose first impression of Diablo is a good one.
• Luminescent Blush Very, very prone to this, especially when it comes to Diablo.
• Tagalong Kid: Had to practically force her way into the party, but she later learns to hold her own in battle.
• Took a Level in Badass: She goes from being a Damsel in Distress to a competent fencer, and even saves Diablo at one point.
• Theme Naming: Her name contains the kanji for "earth", to go with Hinako's "sun" and Natsuki's "moon".
• Those Two Guys: With Natsuki, though unlike the latter, she later graduates to the main cast.
• Violently Protective Girlfriend: Toward Diablo, though she'll insist that she's a Violently Protective Student instead.
• Yaoi Fangirl: One omake strip shows her writing a yaoi fic between Diablo and the protagonist of her favorite vampire novel.

Supporting Cast

Carl Baki

Carl Baki

Michiko's father, a soldier who opposed the Evil Empire during the war. As if the stress from the war wasn't enough, his wife was also killed some time ago.

• Animal Motifs: The wolf, as represented by his ruggedness and his protective nature. Cemented in his Shirtless Scene, in which he's shown with a patch of chest hair shaped like a wolf's head.
• Badass Longcoat: Usually wears a leather trenchcoat.
• Beard of Sorrow: See his chin curtain? It was just a goatee before his wife died. And it grows even longer in jail!
• Dying Moment of Awesome: Despite being gravely wounded by Faust, he ends up weakening him enough for Diablo and co to defeat him.
• Expy: Of the protagonist from the author's Disgaea fanworks.
• Florence Nightingale Effect: His eventual wife was the medic who treated his wounds after his first big battle in the Chaos War.
• Glory Days: Word of God says that in his prime, Carl could have taken down half of the Faustian Cult himself. Compare that to his current position as the Worf of the cast.
• Homage: His design pays homage to both Gendo Ikari and Van Hohenheim. Particularly the beard and face in both cases.
• Humongous Mecha: While he is certainly no slouch on foot, most of his fighting is done while piloting Kamaoh, a 30-foot-tall mech.
• Majorly Awesome: During the Faustian Cult arc, he is a major in the Tengu Town military police. He is posthumously promoted to colonel due to his role in the fall of the Faustian Cult.
• Mr. Fanservice: His ruggedness and Papa Wolf status were added in hopes of attracting fangirls.
• Papa Wolf: He went as far as to desert the military police in order to protect his daughter, and even assaulted General Rossi after she revealed that she was behind Michiko's kidnapping.
• The Rival: To Dr. Suno.
• Shell-Shocked Veteran: He keeps a surprisingly cool head most of the time, but being in a war for 7 years is bound to give someone anger issues.

Suno Tsubame

Suno Tsubame

Hinako's mother. A somewhat paranoid woman who initially suspects that Diablo is just another member of the Faustian Cult.

• Absurdly Youthful Mother: In early chapters, due to the author's self-admitted difficulty with drawing motherly figures at the time. She does look more mature in later appearances, however.
• Housewife: She handles most of the housework, including cooking and cleaning, and also prepares tea for guests, and even sews new clothes for her constantly battle-damaged family.
• May–December Romance: She's 12 years younger than her husband.
• Theme Naming: Going with the other bird names, Tsubame means "swallow"

Ivory Baki

Ivory Baki

Carl's cousin (also making him Michiko's cousin once removed) who works as a mechanic for the military.

• Beware the Nice Ones: He doesn't have a mean bone in his body... until you mess with his family. Then he will stop at nothing to see you pay.
• Bunny-Ears Lawyer: Despite his quirks, he is a very competent mechanic, able to repair Kamaoh within a matter of days after it was put out of commission.
• Camp Gay: Big wardrobe? Check. Many outfits in said wardrobe that show off his skin? Check. Feminine haircut with long eyelashes? Check. Calls everyone "darling", "sweetheart", and other affectionate nicknames? Check-a-rooney!
• The Captain: Although he's more known for his mechanical skills than performing as a captain.
• The Engineer: Actually a mechanic, but still.
• Gender-Blender Name: Averted; Believe it or not, Ivory is actually a unisex name.
• Homage: Personality-wise, he is this to Leeron from Tengen Toppa Gurren Lagann. Design-wise, he heavily parodies Iori Yagami.
• Kissing Cousins: It's more than mildly implied that Ivory has a thing for Carl.
• Navel-Deep Neckline: His main outfit consists of a jacket that only buttons up halfway, leaving him bare from the chest up.

Goto Natsuki

Goto Natsuki

Hinako's other best friend.

• Cute Little Fangs: Usually has these when she's up to mischief.
• Shipper on Deck: Natsuki will tease both Hinako and Michiko about Diablo whenever either of them mention him in conversation.
• Theme Naming: Her name contains the kanji for "moon", to go with Hinako's "sun" and Michiko's "earth".
• Those Two Guys: With Michiko, until the latter ends up joining the main cast.

The Lieutenant

The Lieutenant

A mysterious woman who first appeared in The Stinger of the Faustian Cult arc. Seems to have a bone to pick with Diablo for reasons unknown.Her name is Harada Chiyo, and she is Michiko's older sister.

• Cassandra Truth: She had a connection in the Faustian Cult who told her that General Rossi was responsible for her mother's death. Her father didn't believe her.
• Early-Bird Cameo: Is mentioned by name as early as chapter 7, well before her introduction.
• Hates Their Parent: Has a lot to say about Carl after his death. Little of it is good.
• Nom de Mom: She was born with her mother's surname since her parents weren't married at the time. After moving out, she went back to using it, since she didn't want to be associated with her father.
• Poor Communication Kills: When she hears that Michiko was recently kidnapped, the first course of action she takes is to hunt down Diablo, the only surviving demon of the incident, and try to kill him, even though he's the one who saved her.
• Strong Family Resemblance: Looks more or less like a younger, female version of her father, but with her mother's hairstyle.

General Rossi

General Rossi

A general in the military. She is Carl and Ivory's superior. See Zula below for more tropes.

• Foreshadowing: Her uniform is an early clue that she's Zula, being primarily green with notes of gold and purple, and a subtle hint of space-related imagery.
• Four-Star Badass: Make no mistake. Even though she spends most of her time at HQ, she will take the battlefield if necessary, and she will wreck shop while she's there.
• Freudian Excuse: The reason she wants to make Carl suffer so badly is because she's jealous of his family life.
• The Glasses Come Off: She's seen without eyewear far more often after the revelation that she's Zula.
• Impossibly Cool Clothes: Wears a jacket with buttons that form a big dipper.
• Made of Iron: Diablo even references the trope by name when he mentions it.

Commander King

Commander Caesar King

The leader of the military police. Little else is known about him at this point.

• All There in the Manual: His first name isn't actually mentioned in the comic, but the author has revealed it on Twitter.
• Bald of Authority: While he was still in charge even when he had hair, the loss of said hair has only further cemented his status.
• Expy: Back when he had hair, he looked remarkably like one of the author's Disgaea fan-characters.
• Hair Today, Gone Tomorrow: He's entirely bald now, but he's shown with a rather luxurious mane in flashbacks.
• No Celebrities Were Harmed Word of God says he was drawn with Patrick Stewart on the brain.

Jack Abim

Jack Abim

The friendly ramen stand owner who always listens to Diablo's problems while serving him noodles.

• Dropped a Bridge on Him: Was going to be killed off anyway, but according to the author, it was done sooner than originally intended because he hated drawing him.
• National Stereotypes: The only born Aussie in Tengu Town... who also wears a slouch hat, constantly ends sentences with "mate", and carries a big knoife.

Gelaton Vaznaus

Gelaton Vaznaus

The teacher of Hinako, Michiko and Natsuki's class.

• As Long as It Sounds Foreign: His name is simply a jumble of letters, unintended to mean anything.
• Scary Shiny Glasses: His actual eyes are yet to be shown, only the gleam of his glasses.

Antagonists

Faustian Cult Arc

Loki

The first monk of the Faustian Cult who gets sent after Diablo. He quickly becomes somewhat of a rival to him, each wanting to accomplish their own goals, but especially wanting to beat each other.

• Arrogant Kung-Fu Guy Honestly believes he's the strongest guy in his unit, when he's actually one the weakest monks in the entire cult.
• Badass in a Nice Suit: It's implied to be part of his body, but he's got the look.
• Beware My Stinger Tail: He can grow one, complete with poison. This becomes a plot point later.
• Breath Weapon: His "ultimate attack" is a wide laser that he fires from his mouth.
• The Faceless: Played with. His face is all black aside from his red, glowing eyes, even in broad daylight. Early chapters darkened the background of every frame he was in, but this stopped after his second fight with Diablo.
• Glowing Eyes of Doom: His eyes are constantly glowing red.
• Laughably Evil: His over-the-top design, combined with him becoming less and less threatening with each appearance, serves to make him a villainous example of a comic relief character.
• Magic Pants: His suit vanishes whenever he transforms, but it grows back when he reverts. The suit may be a part of his body.
• Mr. Exposition: Loki's tendancy to reveal things about the Faustian Cult that he shouldn't is lampshaded when he tells Diablo in an almost casual manner how to open the secret entrance to their hideout.
• Names to Run Away from Really Fast: Named after the Norse god of mischief himself.
• One-Winged Angel: During Diablo's final battle with him, he transforms into a therizinosaurus, by far the largest form he's been shown in.
• Playing with Fire: Never shown doing it during a battle, but he uses it to escape after his first fight against Diablo, and in the April Fools' Day chapter he lights a cigarette this way.
• The Rival: To Diablo.
• Slasher Smile: Tends to telegraph his attacks with a huge grin and widening eyes.
• Theme Naming: Loki and Heimdall were named after Norse deities.
• Voluntary Shapeshifting: Much like his namesake, he can morph into various beasts.
• The Worf Barrage: His "ultimate attack" couldn't hit the broad side of a barn. Diablo even manages to dodge it in a narrow tunnel.

Heimdall

Loki's partner, a mysterious and creepy masked gunman. Wears a mask similar to Zula's.

• Almighty Janitor: Despite his low rank, it turns out he's deadlier than many of his own superiors.
• Artificial Limbs: Both of his arms are made of metal. They're removed when he goes to jail, in order to prevent him from using them to break out.
• Brother–Sister Team: With Zula.
• Coat, Hat, Mask: Wears a black jacket with a cowboy hat and a tragedy mask.
• Combat Tentacles In his Poseidon form.
• The Dragon: By default after Zula's death
• Good Scars, Evil Scars: He had a scar across the bridge of his nose until he got a new face.
• The Gunslinger: Wields a revolver in battle, with quite impeccable aim to boot.
• I Have Many Names: He is also known as Luigi Marino (his birth name) and Bruno Ferrari (the false identity he used to flee from America.)
• The Mafia: He and Zula were part of the American Mafia, but got new identities in order to flee the country.
• Making a Splash: Thanks to the Poseidon.
• Mask of Power: His mask allows him to morph into water. He typically saves this ability for rainy days, when it is much more deadly.
• Meaningful Name: In Norse Mythology, Heimdall was the guardian of the Bifrost bridge, and is also described as the "whitest of the Gods". In Demon Blade, Heimdall is the last person to guard the entrance to the Faustian Cult's hideout, and also has white hair and wears a white mask.
• One-Winged Angel: During his final battle in the Faustian Cult arc, he uses the Poseidon to become a large mass of water.
• Red Baron: Heimdall is just a nickname. Albeit one that he came up with himself so the authorities would know what to call him, but a nickname nonetheless.
• Theme Naming: Loki and Heimdall were named after Norse deities.
• White Hair, Black Heart: Even watching his own sister die right in front of him didn't seem to faze him.
• White Mask of Doom: Wears a Greek tragedy mask.
• Wolverine Claws: Has a pair of these hidden in his bionic arms in case he runs out of bullets.

Dogma

Loki and Heimdall's superior, and the first of Dios' Four Avatars. He's actually been looking for a warrior qualified to take down the cult, while deliberately hindering them from within.

• Affably Evil: Justified since the "Evil" part is just an act anyway.
• Extremity Extremist: Dogma almost exclusively uses kicks. In fact, the battle where he loses use of his right arm is the one fight in which he's ever shown throwing a punch.
• Handicapped Badass: After he's stabbed by Heimdall. He can't use his right arm, but he can still, quite literally, kick some tail.
• Heroic Sacrifice: Jumps between Diablo and Dios to save the former from being impaled on the latter's lance.
• Homage: His hair is deliberately drawn to resemble Sonic The Hedgehog, as a nod to the very, very early drafts of the comic.
• Impaled with Extreme Prejudice: How he goes out.
• Last-Name Basis: He has a first name, but almost everyone calls him by his last name. Hinako is the only one who regularly calls him by his first name: Isaac.
• Reasonable Authority Figure: His father was a cop who had a strong sense of justice.
• Red Oni, Blue Oni: One of the Blue Oni to Diablo's Red Oni. Aside from their colors, they are also opposites in three ways:
  • Diablo is a demon who allies himself with humans, whereas Dogma is a human who works with demons. At first, anyway.
  • Diablo dresses like a sophisticated swordsman, in sharp contrast to his brash personality. Dogma, on the other hand, dresses like an average street thug but acts like a gentleman.
  • Diablo performs a usually high-brow combat discipline (swordplay) in a rather unrefined manner, while Dogma takes a typically barbaric fighting style (street brawling) and makes it look far more graceful.
• The Mole: Joined the Faustian Cult in order to take them down from the inside after they killed his parents.
• Scars Are Forever: After his fight with Diablo, he's shown with faint claw scars on his face.
• Sunglasses at Night: He even wears them in the cold, dark depths of Dios' hideout.

Yaibato

An old goblin in charge of the local yakuza gang, and the second of Dios' Four Avatars. He strikes a deal with Diablo and Dr. Suno after Hinako is poisoned.

• Afro Asskicker: His afro is almost as big as he is. He is also a feared crime boss.
• Big Ol' Eyebrows: His eyebrows are bushy enough to obscure the very eyes beneath them most of the time.
• The Brute: Despite his small size, he's able to kick Silver Visage across the room.
• Gag Nose: Comes with the territory of being a goblin.
• Pint-Sized Powerhouse: One of the shortest characters in the series, but has enough striking force to send a Mini-Mecha flying.
• Terrible Trio: The leader of one; Touya and Ishimaru are his subordinates.
• Walking Shirtless Scene: He is bare-chested by default, with only an open jacket covering his upper body.
• Yakuza: A yakuza boss, to be precise.

Touya

Yaibato's right hand man, a kitsune who's addicted to cigarettes, and tends to work in tandem with Ishimaru.

• Animal Stereotypes: Inverted. He's nowhere near as conniving or mischievous as you'd expect a fox to be, instead being quite bombastic and relying on brute force.
• Barefoot Cartoon Animal: He is fully clothed, other than his lack of footwear.
• Butt-Monkey: Gets knocked around a lot during his battle with Diablo, and then gets mistreated some more after he goes to jail.
• Hot-Blooded: Between himself and Ishimaru, he is the louder and more hyperactive one.
• Must Have Nicotine: Once he's in jail, he often complains about not having cigarettes.

Ishimaru

Yaibato's left hand man, an alcoholic tanuki who usually assists in his partner and boss' attacks, rather than directly fighting.

• The Alcoholic: Not as bad as Touya's smoking addiction, though, since he's more often than not seen without a bottle of alcohol.
• Barefoot Cartoon Animal: He is fully clothed, other than his lack of footwear.
• Satellite Character: Has so far only been seen with Touya and/or Yaibato.

Jay von Schlag

The gatekeeper of the Faustian Cult's hideout, who used to be acquainted with Hinako, until her teacher (his father) was killed. He later underwent a Heel–Face Turn, however.

• Bare-Fisted Monk: While he relies more on elemental attacks than Hinako does, he still doesn't rely on physical weapons, and is capable of hitting quite hard with his fists.
• Big Ol' Eyebrows: Jay had quite the brows in his early appearances. They got smaller over time.
• Bruce Lee Clone: Downplayed. His design has plenty to set him apart from the real thing, but the haircut, physique, and martial arts skills are still very much there.
• Casting a Shadow: Primarily uses dark elemental attacks when fighting at a distance.
• Dark Is Not Evil: Most of his techniques utilize the shadow element, but he's among the more noble of the Faustian Cult's monks, and joins the good guys after the raid on Yaibato's mansion.
• Deus Exit Machina: Twice in one sequence is Jay taken out of the action; first he has to haul Heimdall off to the police, and then within the same chapter that he comes back, he gets locked out of Dios' chamber.
• Eyepatch of Power: Wears an eyepatch over his right eye.
• Friend to All Children: The last straw that leads to his defection from the Faustian Cult is Vlad's attempted murder of Michiko. Plus, he only joined the Cult in the first place to gain information about the whereabouts of his missing younger brother.
• Gentle Giant: One of the more physically imposing monks in the Faustian Cult. Despite this, he is rarely seen attacking with lethal force, and will often try to talk his enemies down before resorting to combat.
• Heel–Face Turn: Ends up betraying the Faustian Cult during the raid on Yaibato's mansion.
• Meaningful Name: "Schlag" means "strike" in German. Jay is a martial artist.

Vlad

The third of Dios' Four Avatars, a maniacal and mechanical being who is also incredibly sadistic, and will kill without a second thought.

• Artificial Limbs: Has a metal arm on his face. It gets removed in jail so he can't use it to break out, and after he escapes, he gets another one fitted, this one properly attached to his shoulder.
• Ax-Crazy: Easily the most violent of Dios' Four Avatars.
• Beware My Stinger Tail: His tail has a buzzsaw attached to the end of it.
• Brought to You by the Letter "S": His shirt has a big red "V" on it.
• Cyborg: His right arm, the right half of his face, and the tip of his tail have all been replaced with cybernetics.
• Good Scars, Evil Scars: Has some rather big and nasty scars where his organic body ends and his cybernetics begin.
• Handicapped Badass: Very much a threat, despite nearly half his body being prosthetic.
• High-Class Glass: Wears a monocle over his left eye. Presumably, he can see fine through his prosthetic right eye.

Zula

The fourth and final of Dios' Four Avatars. Appears to be the cult's tactician, formulating most of the plans and strategies that the monks and other three avatars perform.

• Broken Faceplate: After charging face first into a shadow ball from Jay.
• Brother–Sister Team: With Heimdall.
• The Chessmaster: Has manipulated events from both ends up until the events of the story.
• The Dragon: Dios' second in command.
• Dramatic Unmask: At the end of the raid on Yaibato's mansion, Zula appears and reveals herself to be General Rossi in disguise.
• Hoist by Her Own Petard: Deploying Panzer Hades proved to be her undoing, as her superiors in the military police were all too happy to remotely activate its self-destruct sequence after they'd learned her true identity. To add insult to injury, she didn't really even need it at all, as she'd already had the upper hand before she decided to use it.
• Knight of Cerebus Zula's first appearance is the exact moment the comic starts to get serious, by killing Loki.
• The Mafia: She and Heimdall were part of the American Mafia, but got new identities in order to flee the country.
• Mask of Power: The Zeus mask allows Zula to move at superhuman speeds and even teleport.
• Monster Clown: The jester outfit and comedy mask gives this appearance.
• Super Window Jump: Attempts to escape a self-destructing Panzer Hades through the windshield, with predictable results.
• Troll: Takes great joy in creating a Hope Spot for the heroes whenever possible, then crushing that hope into a fine powder.
• Villainous Breakdown: Subverted when she pretends to freak out after Jay crushes her hand, only to reveal that she's actually fine.
• White Mask of Doom: Wears a Greek comedy mask.

Dios

The leader of the Faustian Cult. Dedicated to resurrecting the ancient demon Faust in order to kill Mephisto, his former boss.

• Badass Cape: A bit rattier than Diablo's cape, but it makes him look no less imposing.
• Big Bad: Of the Faustian Cult arc.
• Body Snatcher: That evil emperor in the prologue? Yeah, that was this guy's doing as well.
• Defector from Decadence: Betrayed Zannale after learning of the latter's plan to resurrect Mephisto, and vowed to continue killing Mephisto until the end of time.
• Extra-ore-dinary: Possesses the power of metallokinesis.
• Face Framed in Shadow: Until it's revealed in chapter 13, anyway.
• Finger Firearms: Can turn the iron in his blood into bullets which he fires from his fingers.
• Gag Nose: Well, he is a tengu...
• Meaningful Name: Dios means "god" in Spanish; named both as a direct contrast with Diablo's "devil" and a reference to his attempt at resurrecting Faust.
• Slouch of Villainy: When Diablo finally reaches his chamber.
• Spontaneous Weapon Creation: Uses a lance, which he apparently materializes out of minerals from the ground.
• The Starscream To Mephisto.
• Thanatos Gambit What do you do when you're about to die just one soul short of achieving your ultimate goal? Use your own soul to finish the job.
• Unusual Eyebrows: They're shaped like lightning bolts and they spork at the end!
• Villain's Dying Grace: After he realizes that his attempt to play God did more harm than good, he decides the least he can do is help destroy the abomination he created.
• Well-Intentioned Extremist: He's killed countless numbers of people, but he claims even more would die if Mephisto is allowed to live for too long.

Faust

An ancient demon who Dios is trying to resurrect.

As a Walking Spoiler character, all spoilers regarding this character are unmarked.

• Attack Its Weak Point: All the souls composing Faust's body are held together by a magic stone known as the Tengu Orb. After the stone is broken, he becomes significantly weaker.
• Beam-O-War: Has one with Diablo.
• Greater-Scope Villain: Serves as the cause and the final opponent in the Faustian Cult arc, despite Dios being the main antagonist for most of it.
• Came Back Wrong: Having no physical body or brain, he has no control over his own soul, and thinks of nothing other than absorbing more souls after he's resurrected.
• Fighting from the Inside: After the Tengu Orb is broken in half, some of the more powerful souls contained within it are able to break off from Faust and lend Diablo their power instead.
• Finger Poke of Doom: Can fire lasers from his fingers.
• Immune to Bullets: Doesn't even flinch when shot by the military's tanks.
• Many Spirits Inside of One: The reason Dios caused the deaths of so many people was to completely rebuild Faust's body out of their souls.
• Shapeshifter Guilt Trip: Creates an illusion of Carl's wife to distract him... and then kill him.

Mephisto Arc

Gustavo Zannale

One of Mephisto's last two surviving generals from the Shinigami War. A vampire.

• Face Framed in Shadow: Much like Dios in the previous arc, Zannale's face is always darkened. Even when an old photo is shown where his face should be visible, it's obscured by a speech bubble.
• Prophet Eyes: In contrast to his perpetually shadowed face, his eyes are pure white, even in the dark.
• Sent Into Hiding: After being betrayed by Dios, he went into hiding, long enough for Dios to presume him dead. He comes back with a vengeance after Dios' death.

The Keyman

Zannale's right-hand man. A werewolf.

• Everyone Calls Him "Barkeep": He implies that he has a real name, but chooses not to reveal it. Instead, he tells Diablo to call him the Keyman, after the fact that he holds the keys to the school that Diablo is investgiating.
• Horror Hates a Rulebreaker: Allows Diablo to investigate the school under the one condition that he doesn't try to look through the faculty database to discover Zannale or the Keyman's identity. When Diablo fails to adhere to this simple rule, the Keyman immediately finds out, somehow despite not being in the same room at the time, and gives him a thorough thrashing.
• Lightning Bruiser: One of the few enemies to well and truly defeat Diablo in battle, mainly due to being both fast enough to hit him, and strong enough to slam him into a wall with a mere hook.

Kawazu Gorobei

A masked man who killed Jay's father, and presumably kidnapped his brother as well.

• Coat, Hat, Mask: Wears a tuxedo and a top hat... with a gas mask.
• Lone Wolf Boss: Acts independently of the other villains in the arc.
• Murder the Hypotenuse: Vlad implies that Kawazu was in love with Jay's mother, which was part of his motive in killing Jay's father.

Mephisto

An ancient evil who has been reincarnated many times prior to the events of the story.

• Born-Again Immortality: Is said to reincarnate every time he dies, and Dios implies that his personality remains intact with each incarnation.
• Exotic Eye Designs: His pupils are shaped like inverted pentagrams.
• Greater-Scope Villain: Of the whole comic.
• King Mook: He is an Iblis. The same species as Dios' Adorable Evil Minions from the previous arc.

Thanatos

One of Mephisto's last two surviving generals from the Shinigami War. Currently sealed away.

• The Grim Reaper: While presumably not the actual grim reaper seeing how several characters have already died despite him being sealed away, he is named after the Greek god of death, and looks the part as well.
• Sealed Evil in a Can: Technically still alive, but trapped under such a powerful magical seal that there's nobody on earth both willing and able to undo said seal.
