Main Characters

Staz Charlie Blood

Voiced by: Ryōta Ōsaka (JP), Waku Sakaguchi (JP, as a child), Bryce Papenbrook (EN), Erica Mendez (EN, as a child)

The main protagonist of the series. He is one of the territory bosses of East Demon World. He is the descendant of a noble vampire who would go to the human world to suck blood, but unlike his honored ancestor, Staz shows no interest in this. He is an otaku obsessed with goods from the Human World, especially Japanese games, anime, and manga. Other characters view Staz as a lazy moron who does nothing and has too much free time, but acknowledge his strength and the danger their territory would be in if he were to give up his position. When he sees Fuyumi, he falls in love/bloodlust at first sight and wishes to spend more time with her and to protect her. But just as he gets to know her, she is eaten by a carnivorous plant and becomes a ghost which causes him to lose his initial attraction to her as he is only interested in humans. However, he then makes it his life goal to bring her back to life. In order to bring her back to life, he will do anything; even becoming her vampire bodyguard.

---

• Accidental Pervert: To either Fuymi or Bell. Usually involving getting one or both of them underclothed without intending to do so.
• Act of True Love: In the final chapter, Braz warns Staz that the probability that Fuyumi retains her memories of when she was a ghost is most certainly zero. Braz offers to leave some demonic power in Fuyumi's body so there's a chance she doesn't lose her memories, but Staz tells him to not do that because all he wants is for Fuyumi to go back to her peaceful normal life in the human world, even if she will forget about him. Braz admires the strength of Staz's love for Fuyumi at seeing him so ready to sacrifice his relationship with her for her sake. Although, after Fuyumi is revived, Staz transfers to her class so he can be close to her.
• Affectionate Gesture to the Head: He pats Fuyumi on the head in chapter 64. She finds it uncomfortable and weird.
• Anti-Hero: He directly classifies himself as one since he knows he doesn't have the aptitudes to be a proper hero because of his natural rudeness and selfish goals. He does want to become more heroic for Fuyumi's sake.
• An Arm and a Leg: Burgundy rips off his arm while he was protecting Wolf from her.
• Big Brother Instinct: Shows one to his little sister.
• Can't Live Without You: If Fuyumi doesn't drink Staz's blood on a regular basis, her spirit will disappear due to her extremely low capacity of demonic power.
• Cannot Spit It Out: He doesn't admit his love for Fuyumi until the finale of the manga, having been afraid that he would be rejected if she didn't feel the same way.
• The Champion: At the end of the Hydras arc, Staz makes it his goal to become Fuyumi's hero so he can protect her and bring her back to life because of her wishes instead of his own.
• Character Development: Gets a huge dose in chapter 63.
• Crazy Jealous Guy: He gets easily irritated when he sees Fuyumi close to other men like Wolf, even using his magic claw to get her away from them.
• Creepy Shadowed Undereyes: His eyes have permanent bags underneath to show his nature as a vampire.
• Daywalking Vampire: The sunlight from the human world does bother him a lot, but it won't kill him.
• Declaration of Protection: He proclaims his determination to protect Fuyumi from harm and keep her from disappearing.
• Determinator: Once he begins getting serious about protecting Fuyumi he quickly develops into one of these.
• Eerie Pale-Skinned Brunette: He has black hair and unhealthy-looking skin. Makes sense considering he's a vampire.
• Family Theme Naming: Everyone in his family, including himself, has a name that ends in z.
• Friendly Neighborhood Vampire: He thinks the "bloodsucking wannabe noblemen" vampire image is dumb, and doesn't see why he should go terrorizing humans when they make awesome things like anime and video games.
• Genre Savvy:
  • He has enough sense to realize many of the manga tropes regarding feminine undergarments are fantasy, and whenever he gets his hands on Bell's undergarments, it's Bell using them as a Red Herring to distract him from something else.
  • Staz determines that what is fiction in the human world can be reality in the demon world. Therefore, he and his allies could find a way to defeat the Big Bad by reading his personal manga collection.
• The Gift: Staz had a incredible magic potential since he was a kid, which is why his older brother Braz tried to forcibly awaken it.
• Good Is Not Nice: The main reason why he's more of an Anti-Hero is his utter insensitivity to people's feelings. He does try to improve in that department later.
• Hair-Trigger Temper: A lot of things can piss him off easily, especially in regards to his older brother.
• Healing Factor: Due to being a vampire with high demonic power, Staz is able to instantly heal from any wound. Its effect is significantly weaker in wounds left by silver weapons, though.
• Hilariously Abusive Childhood: When Staz was a kid, his brother tried to induce a Traumatic Superpower Awakening by torturing him and almost killing him several times. The flashbacks depict this in an over-the-top way that's more comical than horrifying.
• Idiot Hero: Not necessarily dumb, but he can't read the mood and most of the time, people who antagonize him tend to lead him around by the nose, especially Braz, his big brother.
• Ignore the Fanservice: While he was uncontrollably attracted at Fuyumi as a human, as soon as she becomes a ghost, the only reaction he has to seeing her stark naked is commenting on how she has lost all attractiveness in his eyes.
• Innocently Insensitive: He is very offensive, especially to Fuyumi, but truly doesn't have any malice or understand what he's doing wrong.
• Interspecies Romance: Staz, a pure-blooded vampire, falls in love with Fuyumi, a human girl-turned-ghost.
• Intrigued by Humanity: He has a love of human entertainment and has stated that Demons would be curb stomped by human technology and numbers.
• Jerkass Realization: After getting a scolding and beating from Heads Hydra, Staz realizes that he has been trying to resurrect Fuyumi for his own self-interests and has never been at her side when she needs him nor listened to what she wants. Staz outright calls himself a villain because of this and decides he'll try his best to be Fuyumi's hero from now on.
• Jerk with a Heart of Gold: He is incredibly abrasive, but generally means well and truly doesn't have any malice.
• Kamehame Hadoken: During his first fight after getting his full powers back, Stanz attempts to pull off a Kamehameha in imitation of his hero Goku. Akim doesn't wait until he finishes charging the Kamehameha before attacking him.
• Lady and Knight: He eventually resolves to be Fuyumi's White Knight who protects her from danger and will do anything to bring her back to life so she can go back to the human world. He's aware his personality isn't very knightly, so he's trying to work on it for Fuyumi's sake.
• Large Ham: Have moments of this, particularly when he gets passionate about anime and manga.
• Leaning on the Fourth Wall: He frequently compares himself to the protagonist of a manga and makes comments about how several situations he finds himself in are similar to those he sees in manga.
• Long-Range Fighter: This, rather than close range combat, is his specialty. Though as the series progresses, he also learns to fight at close range better, especially after being trained by White Step.
• Love at First Sight: Played With. When Staz first lays his eyes on Fuyumi, he thinks she's very cute and feels an uncontrollable urge to drink her blood. After Fuyumi gets eaten by a plant monster and becomes a ghost, he suddenly loses all attraction to her. He at first thinks he can only like Fuyumi when she's human, which is part of why he wants to resurrect her, but he gradually falls in love with her while she's a ghost.
• Maybe Ever After: In the final chapter, Fuyumi is revived by Braz in exchange of forgetting everything from her time as a ghost and Staz moves to the human world so he can transfer into Fuyumi's class. Even though Fuyumi can't remember Staz, the manga ends on the hopeful note that they'll eventually get together again.
• Mega Manning: He tries copying the Kamehameha but it fails.
• Memory-Wiping Crew: In the final chapter, Staz erases the memory of the time Fuyumi was missing from her father and everyone at her school so the resurrected Fuyumi can return to her normal life as if her time as a ghost never happened.
• Meta Guy: As an avid fan of anime/manga, Staz often comments on the clichés and Shout Outs in his series.
• My Fist Forgives You: He finally gets a chance to avenge himself on his elder brother, Braz, but stopped with one punch.
• My Greatest Failure: In the first chapter/episode, Staz carelessly leaves Fuyumi alone to go fight a territory crasher, which results in Fuyumi being Eaten Alive by a Man-Eating Plant. This is Staz's main motivation for the rest of the series to bring Fuyumi back to life and protect her from danger.
• New Transfer Student: The manga ends with Staz arriving as a transfer student at the revived Fuyumi's class.
• Oblivious to Love: He doesn't pick up on Fuyumi's and Bell's feelings for him.
• Occidental Otaku: Staz loves Japanese pop culture, but it's slow to filter down to the Demon World, and he's never been to Japan. In attempt to impress Fuyumi, he dons his hilarious idea of what an average Japanese person wears. The first thing he does when he meets Fuyumi is ask her about manga and games.
• One-Hit Kill: Through the technique in which he attacks an enemy's heart.
• O.O.C. Is Serious Business: If he's recommending caution, that means shit just got real.
• Opposites Attract: With Fuyumi. He's a tactless Jerk with a Heart of Gold and she's a polite Nice Girl.
• Our Vampires Are Different: Staz is a pure-blooded vampire of an elite demon lineage. He lacks virtually all the traditional traits of a vampire and explicitly hates them. He has never drank blood from humans, doesn't burn in the sunlight, can eat normal food including garlic, and crosses won't hurt him. His power decreases if he loses too much blood and he does have a weakness against silver since his Healing Factor doesn't work as fast on wounds left on him by silver weapons. His saliva also has the power to mind control humans and alter their memories.
• Pop-Cultured Badass: He's an overwhelmingly powerful vampire who is a huge fan of Japanese media, mainly manga, anime and videogames. Just to give an example, he tries to pull off a Kamehame Hadoken and directly references Son Goku as his hero while at it.
• Power Limiter: The bullet Braz placed in his heart suppressed Staz's full power. Braz did this because as a child Staz's body couldn't handle his immense power. When the bullet is removed, Staz's power immediately grows exponentially, demonstrated when he destroys the Zombie Brothers (who had been previously wiping the floor with him) in the blink of an eye.
• Red Eyes, Take Warning: He has red eyes to show that he's a very powerful vampire.
• Relationship Reset Button: Fuyumi losing her ghost memories after being resurrected means Staz will have to rebuild his relationship with her from scratch, but his attitude shows he's up for it.
• The Runaway: He ran away from home after he got fed up with his brother's "experiments" nearly killing him.
• Seeks Another's Resurrection: His negligence caused Fuyumi to be eaten by a monster plant and turned into a ghost. He swears to bring her back to life.
• Sibling Yin-Yang: With his older brother Braz. Staz is a reckless, hot-headed Idiot Hero, while Braz is a collected, cunning genius.
• Single-Target Sexuality: Staz never shows even a passing romantic interest in anyone other than Fuyumi.
• Smart Ball: He does occasionally show flashes of great intellect. It seldom lasts.
• Stay in the Kitchen: To Fuyumi, near constantly. It's more than justified in that Fuyumi is far weaker than he is, and is often targeted by antagonists who seek to use her against him, or simply harm her directly, and there's that little incident with the carnivorous plant at the beginning.
• Supernaturally Delicious and Nutritious: Fuyumi develops a strong addiction to drinking Staz's blood. Staz tries to keep this under control by refusing to give her his blood unless her spirit is about to disappear.
• Terrible Artist: His drawings are quite off-putting.
• Thanks for the Mammary: In Chapter 52, he grabs Fuyumi's chest while shielding her from Burgundy (who wants her breasts for herself). He's still clutching her chest when they're safely back in Knell's grid room, with Fuyumi being too embarrassed to say anything.
• Took a Level in Kindness: Early in the series, Staz is only trying to make Fuyumi human again because he wants to suck her blood and he readily places her as the prize in a duel with his rival Wolf. After his meeting with Heads Hydra and hearing about what a good man Fuyumi's father is, Staz resolves to start treating Fuyumi with respect, as well as being more considerate to her feelings and wishes. He's no longer going to resurrect her because of what he wants, but because of what she wants.
• Unresolved Sexual Tension: It's obvious Staz and Fuyumi like each other, but they doesn't make it clear to each other for nearly the entire manga. In Staz's case, it's because he sucks at figuring out how others feel unless they outright tell him, so he didn't want to make a move on Fuyumi until he was sure she felt the same way about him.
• Unskilled, but Strong: He doesn't exactly have style or technique, except when he tries to copy something from manga or anime, and even then, fails at that, so he often prefers to just steamroll every opponent in his way.
• The Un-Smile: After deciding to be nicer to Fuyumi, he tries smiling to make her feel at ease. He only ends up freaking her out with how creepy his forced smile looks.

Fuyumi Yanagi

Voiced by: Iori Nomizu (JP), Xanthe Huynh (EN)

The human girl who becomes lost in the Demon World after wandering into a portal that suddenly opened up in her bedroom. She becomes a ghost after being eaten alive by a carnivorous plant, leaving behind only her bones and clothes. She wishes to be resurrected and become human again, and accompanies Staz on his quest to bring her back to life.

---

• All Your Powers Combined: As a ghost, Fuyumi has the ability to absorb the mind and abilities of other monsters. During the Final Battle against Herrschaft Grimm, Staz has Fuyumi absorb him, Wolf, Bell and several other demons to create the ultimate demon hybrid who can defeat Grimm once and for all.
• Amnesiac Lover: At the end of the series, Fuyumi is resurrected as a human, but in exchange, she forgets all about her time as a ghost and therefore, about Staz. She still kept a photo of herself and Staz before being revived and Staz arrives as a New Transfer Student at her class to be close to her.
• Back from the Dead: She's successfully resurrected as a normal human by Braz in the final chapter.
• Betty and Veronica: The Betty to Bell's Veronica. Fuyumi is the normal and sweet girl from the human world who Staz must protect from the dangers of the demon world, which invokes the jealousy of the Tsundere Dimensional Traveler Bell.
• Butt-Monkey: Nothing ever goes right for her, not for very long at any rate.
• Buxom Beauty Standard: Burgundy goes after her because she thinks Fuymi's breasts are a "good part" due to the fact that they're bigger than her own.
• Character Development: Since the beginning of the training arc with White Step, she's slowly started to stand up for what she believes (she punched Staz when he talked poorly to Bell, forced him to drink water when he was pushing himself too hard and toyed with him during the team race).
• Children Do the Housework: Since her mother was never around as long as she remembers, Fuyumi is the one who cooks at home for herself and her father.
• Conveniently Seated: In her class at the human world, she has the second-to-last seat next to the window. In the final chapter, the New Transfer Student Staz gets the seat next to her.
• Cool Big Sis: She adores Liz and treats her as if she was her own little sister.
• Cute Ghost Girl: Becomes a ghost not too long after entering the demon world and she's definitely on the cute side.
• Cuteness Proximity: She loves cute things like little animals and Staz's little sister Liz.
• Damsel in Distress: She's repeatedly getting into trouble or kidnapped, motivating Staz to save her.
• Dead to Begin With: Fuyumi gets eaten by a plant monster at the beginning of the story, reincarnating as a ghost who was eventually given new flesh but also a constant helping of Staz's blood to keep herself tangible. Staz's goal is bringing her back to life as a human.
• Death Amnesia: Fuyumi is brought back to life by Braz at the end of the manga, but she loses all her memories of when she was a ghost as a result.
• Distress Call: Fuyumi used the moment her kidnapper Knell reopened a way between dimensions to send a distress call with Bell's bell. Then, she shot Rasodo of Team Fearless (the big mummy guy) while she was imprisoned in his body, showing her position to Staz.
• Eaten Alive: At the start of the series, she gets eaten by a Man-Eating Plant off-panel.
• First Girl Wins: Fuyumi is the first girl Staz meets at the start of the series and he never feels attracted to anyone but her, to Bell's dismay.
• Forgotten First Meeting: She and Bell met when they were both around 2 years old.
• Friendly Ghost: While she turns into a ghost at the start of the series, Fuyumi isn't scary at all and treats everyone very kindly.
• Grew a Spine: Over time, Staz tells Fuyumi to stop passively going along with what he says and encourages her to speak up her mind.
• He Is Not My Boyfriend: When Liz introduces her as Staz's girlfriend to hers and Staz's father, Fuyumi tries to deny it in embarrassment even though it's all but officially true.
• Innocent Blue Eyes: Sports a pair of big blue eyes and she's easily one of the most innocent characters in the series.
• Innocent Fanservice Girl: Absolutely sweet and almost always dressed in skimpy wear.
• Interspecies Romance: Fuyumi, a human girl-turned-ghost, falls in love with Staz, a pure-blooded vampire.
• Killed Offscreen: In the very first chapter/episode, Staz leaves Fuyumi alone in his room to defeat a territory crasher. When he comes back, he finds a Man-Eating Plant devoured Fuyumi and left only her bones, while Fuyumi's soul is still around as a ghost.
• Lady and Knight: Fuyumi is the kind-hearted and gentle Bright Lady who Staz is determined to protect.
• Love Revelation Epiphany: Until near the end of the manga, Fuyumi doesn't know how Staz feels about her nor how she feels about him, even thinking she's only drawn to his blood. It's until Staz finally spells out his feelings for Fuyumi that she understands that he loves her and she loves him back.
• Maybe Ever After: While Fuyumi loses her memories of Staz after being resurrected, the final chapter implies a part of her heart still remembers him and since they're now classmates, they have high chances of becoming a couple again down the road.
• Ms. Fanservice: Fuyumi has a tendency to end up in rather fanservice heavy costumes, the School Swimsuit bunny ring girl outfit being a standout example.
• Naked on Revival: In the final chapter, Braz restores her human body back to normal in a Healing Vat and, of course, Fuyumi is naked during the revival process.
• Nice Girl: Very supportive and friendly to everyone.
• Opposites Attract: With Staz. She's a polite Nice Girl and he's a tactless Jerk with a Heart of Gold.
• Our Ghosts Are Different: Even though she's a ghost, she can't fly, make stuff float, phase through things nor possess people. By drinking the blood of a vampire, Fuyumi can gain the ability to absorb and utilize multiple types of magic from other demons.
• Plot-Triggering Death: Fuyumi's death and transformation into a ghost in the first chapter/episode set Staz out in the quest to bring her back to life.
• Protectorate: Staz's main motivation for nearly everything he does is protecting Fuyumi.
• Ridiculously Alive Undead: The only thing different about Fuyumi after becoming a ghost is that she's wearing the triangle-shaped headband that Japanese ghosts normally have. She can eat and sleep just like when she was alive. The real problem is she'll disappear if she returns to the human world, so she wants to return to being human and go back home.
• Shrinking Violet: She's shy and mostly quiet, but since she met Staz, she has started to show more emotions and express her opinion. Staz even requested her to do that because he couldn't know what she was thinking, and wished to know more sides of her personality.
• Signature Headgear: After becoming a ghost, she wears a hitaikakushi on her head to signify that she's dead.
• Single Woman Seeks Good Man: She falls in love with Staz for his better qualities that are hard to see beneath his rude personality, mainly his determination to bring her back to life and protectiveness towards her.
• Tareme Eyes: Her eyes are big and round, fitting her cuteness and docile personality.
• Too Much Information: When describing to Knell how it feels like when she wants to drink Staz's blood, Knell tells her to save up the details.
• Took a Level in Badass: A massive one in Volume 16, where she becomes instrumental in the defeat and downfall of Herrschaft Grimm. Downplayed since it's Staz who is actually in control of her body and uses her physical and magical specificities, while Fuyumi's mind is just sitting inside her head. She briefly retakes control to tell Grimm she isn't alone fighting him.
• Took a Level in Jerkass: It seems she's been around Staz's Innocently Insensitive Jerk with a Heart of Gold personality too long by chapter 63. She begins to snark, demean and outright bemoan him while they're undergoing Bell's "food gathering" race.
• Trapped in Another World: After becoming a ghost Fuyumi isn't powerful enough to survive in the Human World for more than a few hours before disappearing so she must stay in the Demon World until she is resurrected.
• Tsundere: A very mild Sweet type. Fuyumi only ever gets mad at Staz. The way he switches from his rude personality to being nice and caring to her upsets Fuyumi and her own uncertainty about her feelings for him gets her worked up.
• Unresolved Sexual Tension: She and Staz have a strong attraction to each other that neither act on for a long time. In Fuyumi's case, she's naturally shy and wasn't sure how of she feels about Staz and his evident changes in behavior towards her until he admits he's in love with her in the final chapters.
• Wistful Amnesia: At the end of the manga, Fuyumi is resurrected without any of her memories of her time as a ghost. Yet, she can sense the photo she kept of herself and Staz is important to her and when Staz shows up as the New Transfer Student at her class, she calls him "Staz-san" as she did before, implying that a part of her might subconsciously remember him.

Bell Hydra

Voiced by: Sarah Emi Bridcutt (JP), Kira Buckland (EN)

Bell is a treasure hunter who can travel through dimensions using frames. She is a high level user of spatial and teleportation magic and the owner of the Black Curtain that brought Fuyumi to the Demon World. She wants to catch the magic thief who stole her Black Curtain and make him her husband. At first, she thought Staz was the magic thief, but after several investigations, it is known that the magic thief is dead. She starts to fall in love with Staz after Staz fulfills her wish to see his true power (unintentionally).

---

• All Girls Want Bad Boys: Bell wants to find the guy who stole her magic... so she can make him her "lover boy".
• Betty and Veronica: The Veronica to Fuyumi's Betty. Bell is the provocative girl of the demon world and Dimensional Traveler who is attracted to Staz, but her aggressive Tsundere personality makes her much harder to deal with than the sweet and defenseless Fuyumi. Bell is endlessly frustrated by how blatantly Staz prefers Fuyumi while he won't ever even consider her romantically.
• Big Brother Bully: Well, Big Sister, The most frequent victim of her violence is her younger brother, Knell.
• Child Prodigy: Bell has been able to create a Black Curtain between the Human and Demon Worlds (something only high level demons are capable of) since the age of about 2.
• Clingy Jealous Girl: She spends a lot of time frustrated and jealous over the attention Staz gives to Fuyumi, often taking it out on the guy violently. She only drops this after she understands Staz dumping Fuyumi for her isn't something that would make her happy either.

• Girlish Pigtails: She often ties some of her hair into little pigtails.
• Goggles Do Nothing: She's usually wearing goggles on her head, but never actually does anything with them.
• Goofy Print Underwear: While fighting Staz to test his strength, he accidentally removes Bell's underwear and finds they have a childish rabbit design. However, Bell is less embarrassed by this than the fact that he also discovered her Treasure Note diary that contains details of Operation: Get-Staz-To-Love-Me.
• Groin Attack: Does this on her younger brother Knell.
• He Is Not My Boyfriend: She has this reaction when Wolf's mother asks her if she's her son's girlfriend. In the final chapter, she also denies it in embarrassment when Staz teases her about how well she and Wolf have been getting along lately.
• Hopeless Suitor: Bell has a crush on Staz, but he only has eyes for Fuyumi.
• Hypocritical Humor: She makes fun of Staz's love for manga and anime and his view of life through them. Yet Bell likes doing things you can see in teen drama TV series.
• I Want My Beloved to Be Happy: She eventually admits to Staz that she's serious about her crush on him, but she has also realized the Staz she wants is the one who is devoted to protecting Fuyumi. If Staz were to forget about Fuyumi and fall for Bell instead, Bell would come to hate him, so she won't get in the way of Staz and Fuyumi.
• In Love with Your Carnage: After Staz unlocks his power, she realizes that she finds Staz incredibly attractive because of his strength.
• Large Ham: She enjoys changing costumes and making big entrances.
• Long-Lost Relative: She's, in a sense, Fuyumi's half-sister since their mothers were doppelgängers who merged together. Neither of them knew about this until Neyn brings Fuyumi to the Hydras' home.
• Love Hurts: Knowing Staz won't ever look at her in the same way he looks at Fuyumi brings her constant angst and frustration.
• Loving a Shadow: Katy (Wolf's mother) makes Bell realize that Bell is more attracted to the man Staz is because of Fuyumi and the idea that someone could fight for her like Staz does for Fuyumi than to Staz himself. Without Fuyumi, Staz would still be a lazy otaku whom Bell would have never looked at. Bell then admits to Staz that she would definitely hate him if he came to reciprocate her feelings and stopped protecting Fuyumi.
• Maybe Ever After: The final chapters mention Bell has been traveling with Wolf and they're close enough for Staz to tease Bell about it, but there's nothing concrete about them potentially being an item.
• Ms. Fanservice: She's right up there with Fuyumi as far as wearing fan-service heavy outfits..
• Not What It Looks Like: Almost immediately after her Freak Out regarding Fuyumi's Not What It Looks Like moment, she gets into her own with Wolf. Staz doesn't even flinch and just turns away.
• Playful Cat Smile: Her default expression, showing her curious and mischievous personality.
• Ship Tease: Frequently with Wolf, though neither of them wants to admit it.
• Sour Supporter: While she's treated as part of Staz's team, Bell doesn't want to be involved in the battle against the monsters Akim and Grimm, much less cooperate with Staz who's the target of her unrequited crush and keeps hurting her by choosing Fuyumi over her.
• Teleportation: She has powerful access to spatial and teleportation magic.
• Training from Hell: Takes over on delivering this to Staz and Wolf from White Step. She makes it even harder and more dangerous than White Step outlined for her own amusement.

Wolf

Voiced by: Takuma Terashima (JP), Mikio Kato (JP, as a child), Ben Diskin (EN), Julie Ann Taylor (EN, as a child)

He is the hybrid werewolf (the English manga uses lycanthrope in place of werewolf) who controls most of West Demon World. He is Staz's friend and rival, having known each other since Staz ran away from Acropolis. He seems to be attracted to Fuyumi when he first sees her, but is very shy about it. He is of noble blood and was supposed to live in Acropolis, but admitted that he was abandoned because he is not a pure-blooded werewolf. According to himself, he is "a mongrel".

---

• Accidental Pervert: Not as often as Staz, but he has been caught in a Not What It Looks Like scenario with Bell in her underwear on one occasion.
• Anime Hair: He has gravity-defying spiky hair that makes him look like a Super Saiyan.
• Blood Knight: Has no interest in money or power even though he controls most of West Demon World at the beginning of the series. Wolf only wants to fight strong opponents, which is why he constantly wants to fight Staz even though the latter is stronger.
• Childhood Friends: With Staz. They first met right after Staz literally fell from the sky to escape from his home and underneath their rivalry, they're best friends.
• Close-Range Combatant: Is this, in contrast to Staz. Though devastating in close quarters combat, Wolf has difficulties against opponents who are either able to stay out of his range or hold out for three minutes against him (the maximum time that Wolf can maintain his transformation). Until he receives training from his mother to master the magic ability Charisma he inherited from her, that is. This magic allows Wolf to use his demonic power as a vacuum to draw an opponent and anything he focuses on within close range for him to attack.
• Don't You Dare Pity Me!: He hates it when Staz holds back in their fights, even though both of them acknowledge that Staz going all out would likely kill him.
• Family Eye Resemblance: He has his mother's eyes, which is how he can recognize her the first time they meet.
• Friendly Rival: To Staz. Wolf is annoyed that Staz never gets serious at their duels because Staz doesn't want to really hurt his close friend.
• Hidden Depths: One would never know it by looking, but he's a great chef. For a mere 2000 yen (approx $20 US) he makes a meal fit for three with ease.
• Like Parent, Like Child: He has most of his mother's personality and delinquent background. Bell even thinks that there's no doubt they're mother and son when the two start arguing the moment they first meet.
• Maybe Ever After: The two final chapters make brief hints at Wolf and Bell becoming closer, but the feelings between the two are still fairly ambiguous.
• Our Werewolves Are Different: Wolf is a mixed-blood werewolf, giving him the ability to transform into an anthropomorphic wolf at will and his powers have no connection to the cycle of the moon.
• Non-Human Humanoid Hybrid: Wolf's father is a noble werewolf (and the reigning King of the Demon World), but since Wolf isn't pure-blooded, his werewolf powers aren't as strong.
• Parental Abandonment: His parents abandoned him when he was a baby, not that he's bothered by it.
• Real Men Cook: He reveals that he learned to cook so he could provide "good" meals to his gang.
• Ship Tease: Frequently with Bell, though neither of them really notices.
• Vitriolic Best Buds: While Staz and he quarrel near constantly, they are very close friends.
• Wolverine Claws: His werewolf can grow long claws that fire powerful shockwaves.

Staz's older brother. He is the one who wrote the book of resurrection that Staz and the others believe can bring Fuyumi back to life. When they were younger, he conducted experiments on Staz to unlock his true potential.

---

• Aloof Big Brother: He isn't exactly the best older brother you could have. Liz has been trying to gain his attention for years without any sign of success. On the other hand, Staz ran away from home because Braz's "attention" was too much for him.
• Ambiguously Evil: Throughout the first half of the manga, his motivations are unclear and it's really hard to tell if he does care about Staz in some way or is really trying to get rid of him. It's eventually revealed that while Braz is definitely manipulative and focused on his own goals, he isn't evil and everything he did, from almost killing Staz to awaken his great demonic power and helping in the creation of the undead monster Akim, was part of a plan to resurrect his father so the latter could reclaim the throne.
• The Bait: During the Final Battle, Braz steals Akim's heart, which is the power source of Grimm's host body, and implants it inside his own body. Braz's master plan to kill Grimm is forcing him to chase after him all over the demon world until he eventually runs out of power.
• Big Brother Bully: To seriously abusive levels. He performs horrifically abusive experiments on Staz, and almost completely ignores Liz.
• Bloody Murder: Braz's magic is able to control his blood from any distance, allowing him to do things such as send messages or create a small scythe wielding puppet.
• Characterization By Action: He frequently pushes his glasses up his nose by the bridge. This makes it easy to identify him as a manipulative and calculating type of character.
• Classical Movie Vampire: As opposed to his younger brother Staz, Braz does fit the image of the vampire nobleman wearing a black long coat with a high collar and exhibiting a sinister yet gentlemanly demeanor.
• Create Your Own Villain: He killed Wolf Daddy's messenger and gave the corpse to Dr. Franken Stein who made it the core of Akim. This was all part of Braz's plan to use the Akim's heart to bring his father Richardz back to life. It would all turn around and come to bite him, hard, in chapter 41. Akim takes his heart back from Richardz, killing him a second time, and Akim assimilates the power of the evil first king of Makai Herrshaft Grimm. Akim then proceeds to throw all of Makai into chaos.
• Creepy Shadowed Undereyes: Like his brother Staz, Braz has dark circles under his eyes as part of him being a vampire.
• Defiant Captive: Braz spends the second half of the series as Akim/Grimm's prisoner and pretends to obey him, but he's actually plotting to find a way to kill him the entire time.
• Eerie Pale-Skinned Brunette: As a vampire, Braz has jet-black hair and extremely pale skin like his younger brother. Braz's manipulative personality and cryptic plans put him deeper into the "eerie" territory than Staz.
• Four Eyes, Zero Soul: He's a Manipulative Bastard who wears glasses and stands out because of his poor treatment of his younger siblings.
• Freudian Excuse: The death of his father and mother at the hands, both directly and indirectly, of Herrschaft Grimm made him very bitter and cruel.
• Heroic Sacrifice: Combined with Taking the Bullet. Surprisingly in between the end of Chapter 45 and the beginning of chapter 46. He survives but becomes Trapped in Villainy as a result.
• Hoist by His Own Petard: Using Akim as a vessel to harvest Mazoku and then resurrect his father turns around and bites everyone in the ass when Akim decides to take his heart back, and reduce Braz's father to Ludicrous Gibs in the process.
• Jerk with a Heart of Jerk: He agrees to resurrect Fuyumi so he can extract Staz's demonic power within her ghost form and use it for his own ends.
• Mysterious Middle Initial: We don't know what the D. initial in his name stands for.
• Necromancer: He resurrected his father, Richardz to avenge himself on Wolf Daddy. At the end of the manga, he also brings Fuyumi back to life.
• Nice Job Breaking It, Hero: While he's an Anti-Hero at best, Braz screws over big time by not disposing of Akim's body after using his heart to resurrect Richardz. Turned out Akim's undead body still had enough demonic power to function. Therefore, Akim uses his teleportation powers to take back his heart and drink Richardz's blood, which results in Richardz dying a second time and Akim absorbing Richardz's power.
• Promotion to Parent: With both of their parents dead, Braz is the only guardian of his little sister Liz, which is why she craves for his attention so much.
• Scary Shiny Glasses: His glasses look like this when he's being shady or tormenting his younger brother.
• Sibling Yin-Yang: With his younger brother Staz. Braz is a collected, cunning genius, while Staz is a reckless, hot-headed Idiot Hero.
• Terrible Artist: When his blood puppet draws a map, the first thing Staz and his friends think is how much Braz sucks at drawing.
• Tragic Keepsake: His coat originally belonged to his deceased father. Braz gives it back to his father after successfully resurrecting him.
• Vampire Monarch: After the Final Battle against Grimm, Braz ascends to the throne as the new vampire king of Makai.
• Vicariously Ambitious: He wants to take Wolf Daddy down from the throne, but he's preparing someone else to become king of Makai. More specifically, he's working to resurrect his father so the latter can take back the throne Braz believes is rightfully Richardz's. In the end, however, Richardz doesn't want to become king again and dies again because of Akim. So, Braz ends up becoming the new king of Makai.
• "Well Done, Son" Guy: When his father Richardz lived, Braz wanted to prove him he was worthy to be his successor. He never got over that Richardz chose Wolf Daddy as the next king instead of him.
• You Killed My Father: He's constantly scheming to destroy Wolf Daddy in return for latter murdering his father. He drops the antagonism when he learns Wolf Daddy killed Richardz as part of an I Cannot Self-Terminate scenario. His target of revenge then changes to Herrshaft Grimm and Akim, who are responsible of killing his father twice.

Liz T. Blood

Voiced by: Yuuka Nanri (JP), Sherry Lynn (EN)

Staz's little sister. She is the jailer of Acropolis and has the power to judge and imprison demons in her own personal dungeon known as Liz's Toy Box.

---

• Annoying Younger Sibling: To Staz. And by "annoying" we mean that the moment they meet for the first time in years she tries to split him in two with her axe, refuses to acknowledge him as her brother and throws him in prison out of a grudge that he's still Braz's favorite sibling. She thankfully gets a lot better.
• Badass Adorable: She's incredibly cute, yet as a noble vampire she is also extremely powerful and feared as the jailer of Demon World Acropolis. Whether she actually is that dangerous or if it's due to propaganda is unknown.
• Big Brother Worship: Shows an unhealthy amount of this towards Braz.
• Cool Mask: Liz often hides her face with a hockey mask. She later gets a Tengu mask from White Step.
• Curtains Match the Window: Red hair to match her red eyes.
• Cuteness Proximity: Whatever attitude she has goes out the window whenever she sees anything remotely cute.
• Does Not Like Spam: Dislikes sour food.
• Fiery Redhead: A redhead and has a personality that's definitely on the fiery side.
• Girlish Pigtails: Her hair is pulled up into twintails that look adorable in a little girl like her.
• Girls Love Stuffed Animals: She loves cute stuffed animals, although she'd never admit it out loud. She warms up to Staz a little after he buys her a stuffed animal he knew she wanted.
• Little Miss Badass: As a noble vampire, Liz is far stronger than her youth and size implies.
• Lonely Rich Kid: Because of her high-ranking status, she believes that those who are kind to her are usually just trying to suck up to her and her family, so she cannot make any true friends. Her parents are dead, one of her brothers doesn't pay attention to her and the other left home long ago.
• Mysterious Middle Initial: Like Braz, it's not made clear what the T. in her name stands for.
• Nice Girl: She genuinely is a very kind girl.
• The Nicknamer: She's often seen giving nicknames to people. Chief of Police Goyle has been called "Hedgehog" and "Chestnut Head" as an example.
• Older Than She Looks: Liz looks between only 5 and 9, but she can't be younger than 10 because her parents died that year, and she seems to have some memories of them (she recognized her father in chapter 39). She must be 11 to 14 years old (about Knell's age).
• The Resenter: At the beginning of the series, Liz holds a deep disdain for Staz because Braz would spend all his time on him.
• Sleep Cute: She and Fuyumi sharing the same bed at the end of chapter 19 is absolutely adorable.
• Strong Family Resemblance: From what we see in flashbacks, Liz takes after her deceased mother.
• Token Mini-Moe: Youngest character of the series.
• Tsundere: She slowly does come to like Staz as her brother, not that she wants to openly show it.
• Vader Breath: The anime gives Liz this style of breathing whenever she is wearing a mask.
• "Well Done, Daughter!" Girl: Little sister version. She wants to be a "good girl", so that she can be of optimum use to Braz, and hopefully win over his affection.

Akim and his "children"

In General

• Artificial Family Member: Akim's "children" are Artificial Zombies made from the strongest body parts of demons he killed and reanimated with his and Grimm's demonic power.
• Artificial Zombie: They're all corpses made of the body parts of several demons and animated by magic.
• Colourful Theme Naming: Noticed by Braz that the names of Akim's "children" (Burgundy, Kelly Green, and Amber) are all colors. This is because Herrshaft Grimm liked to give his personal forces names of colors, so Akim is doing the same as a result of absorbing Grimm's power.
• Feel No Pain: As reanimated corpses, they're completely incapable of feeling pain.
• Frankenstein's Monster: Akim is a monster created by Dr. Franken Stein from the body parts of several demons stitched up together. Akim later creates his "children" in the same way.

Akim Pablodon

^{Click to see his appearance after assimilating Grimm}

Voiced by: Koji Yusa (Japanese), Lucien Dodge (English)

A monstrosity created by Franken Stein stitched up by the body parts of demons.

---

• Ax-Crazy: He gives The Joker a run for his money in this department.
• Cannibalism Super Power: After a fashion. He makes himself stronger by stealing and assimilating body parts of other Mazoku.
• Chest Burster: He uses his teleportation powers to burst out of a boar demon's belly. He also does this to Richardz after taking back his heart from the vampire's chest.
• Character Tics: Hair-twirling.
• Coat Cape: After killing Richardz, he wears his coat like a cape.
• The Corruption: He is so eager to take Grimm's powers that he fails to realize that Grimm comes with them.
• Disc-One Final Boss: He acts the main villain for nearly the entire series, but just before the Final Battle, Herrshaft Grimm takes over the role of Final Boss by completely consuming what's left of Akim's personality.
• Dying as Yourself: Tragically subverted. Akim notices the corruption due to Grimm faster than anyone, and is well aware that Braz plans to kill him with poison. After being offered a Morton's Fork, to decide which death would be more "beautiful," Grimm takes over before he has a chance to answer.
• Explaining Your Powers to the Enemy: He explains how his abilities work while he fights. Justified in that he only explains it after he's beat down and crippled his opponents, to further demoralize and humiliate them.
• Expository Pronoun: At one point, Braz notices Akim uses the first-person pronoun "ore" instead of "boku" as he usually does. This is a hint that Grimm is slowly taking control over Akim.
• Expy: He shares several traits with Cell from Dragon Ball Z.
• Eyes Do Not Belong There: After killing several demons and taking their body parts, Akim now has eyes on his chest and upper arms.
• Feed It with Fire: After assimilating Ricardz Blood, using magic on him only serves to make him stronger, as Wolf Daddy found out, the hard way.
• For the Evulz: He really doesn't have a reason for all the bloodshed and chaos he's causing, he just enjoys doing it.
• Gone Horribly Right: Wolf Daddy was looking for someone strong enough to oppose Grimm. Akim qualifies, but actually wants Grimm's power for himself, and used his new powers to blow the door to Grimm's cage, permanently.
• Grand Theft Me: After Akim absorbs his power, Grimm slowly takes full control over Akim's body and overwrites his personality.
• Humanoid Abomination: He becomes one after assimilating Grimm.
• In Love with Your Carnage: He calls the death and destruction he causes "beautiful" along with the people he kills.
• Laughing Mad: He is very often laughing like a loon, especially when he's in battle.
• Loss of Identity: As he notices Grimm's demonic power inside him is getting stronger, Akim becomes terrified that he's losing himself to Grimm and doesn't even know how much of his will is his own anymore.
• Mix-and-Match Critter: He's been running around grabbing body parts from various Mazoku to improve himself.
• Not Himself: After Akim assimilates Herrshaft Grimm's power, Braz gradually notices that Akim is not acting as his regular self, such as switching first-person pronouns from "boku" to "ore" and losing his Psychopathic Manchild traits. These are all signs that Akim is slowly losing himself to Herrshaft Grimm.
• Not Quite Dead: Braz should really have destroyed the corpse when he had the chance.
• Power Copying: When he touches Mazoku for any length of time, he can copy their powers and abilities.
• Psycho for Hire: Until he decided he should be in charge.
• Psychopathic Manchild: Causing mayhem and carnage is all a fun game to him.
• Readings Are Off the Scale: One of the first things he does is make Braz manufacture a power sensor so he can find the "best" parts. An initial test on himself reads at approximately 190,000. It only keeps going up from there, no matter how fast or flashily he spends his power.
• Scary Teeth: They are all pointy and razor sharp.
• Spanner in the Works: Wolf Daddy, Braz, and even Richardz's plans all went up in smoke thanks to him.
• Spiky Hair: After upgrading himself by taking the most powerful body parts he can find, Akim's hair looks like spikes sticking out from his head.
• Teleportation: He copied Heads Hydra's teleportation magic, which he uses with his rings.
• Truly Single Parent: Using his demonic power comnined with Grimm's, Akim creates three Artificial Zombies like himself who he calls his children.
• Vagina Dentata: The largest seam across his chest opens to reveal a large mouth with sharp teeth, which allows Akimu to consume others.
• Walking Shirtless Scene: He never wears a shirt.
• Wave-Motion Gun: He can fire these from his body.
• What Happened to the Mouse?: Akim's personality appears to be completely overwritten by Grimm, but his "child" Kelly is still able to sense Akim's demonic power and demands Braz to save Akim. While Akim's heart is successfully retrieved from Grimm without being destroyed, nothing in the epilogue even mentions what became of it after Grimm was destroyed.
• The Worf Effect: On both ends of this. He gets worfed by Staz when Staz got his limiter removed, only to turn around and Worf Richardz, Wolf Daddy, and Staz after stealing Richardz's powers when he took his heart back, and then Worfs all of Makai after assimilating Grimm.

Burgundy

One of Akim's first "children."

---

• Ambiguous Innocence: Sees ripping people apart as nothing more than a game, but truly does not understand why that's wrong.
• Call to Agriculture: After Grimm's final defeat, Burgundy goes to live with Patty at his farm in the mountains.
• Combat Sadomasochist: Despite not being able to feel pain, she thinks a blow to the chin, supposedly able to liquefy her brain, is fun, and asks White Step to do it again. This in addition to enjoying ripping people apart.
• Cute and Psycho: She acts like a playful and innocent child, yet turns vicious and unstable when she's low in demonic power, complete with the nightmarish Slasher Smile.
• Domino Mask: She wears a mask that covers the area around her eyes.
• Foolish Sibling, Responsible Sibling: The foolish to Kelly's responsible. Burgundy acts like a child who only wants to have fun and she fails to play her "father" Akim's "games" right because she's so forgetful and easily distracted. Her sibling Kelly, on the other hand, is more serious and calls Burgundy irresponsible.
• Forgetful Jones: She often forgets what she's doing, or why.
• I Just Want to Have Friends: After meeting Patty, she wants to have friends, because Patty, rather than trying to kill her or beat her down, wanted to make friends with her instead.
• It Amused Me: She just wants to be entertained. If she's given something to do that's fun, she will happily overlook fighting and killing people.
• Little Bit Beastly: She has bunny ears and a fluffy bunny tail.

Kelly Green

The second of Akim's "children."

---

• Ambiguous Gender: There's considerable debate, in universe, if Kelly is a boy or girl.
• Ambiguously Evil: It is not certain if Kelly is "just following orders" or really enjoys going out and engaging in wanton slaughter and destruction. In any case, Kelly really doesn't have a chance in trying to defy Akim.
• An Arm and a Leg: One of the first things Akim does to test his most recent "child," Amber, is have Kelly and Amber try to remove each other's body parts. Amber rips off one of Kelly's arms before Akim even says "start."
• Even Evil Has Loved Ones: It's apparent that Kelly cares about the family, mainly Akim and Burgundy.
• Foolish Sibling, Responsible Sibling: Kelly has this dynamic with Burgundy. While Kelly is serious and focuses on playing the "games" of their "father" Akim effectively, Burgundy is childlike, easily distracted and tends to lose track of what she's doing.
• Horned Humanoid: Has small devil horns.
• Losing Your Head: Kelly's "father" and "siblings" have removed Kelly's "head" as part of games. Siam Kid gets worried about this, but Kelly can reattach the head just fine.
• Perpetual Frowner: Always has a scowl.
• Sixth Ranger: The epilogue shows Kelly joined Team Fearless after Grimm's defeat.
• Undying Loyalty: Kelly is unquestionably loyal to Akim.

Amber

The third, last shown, and most powerful of Akim's "children."

---

• Ambiguous Innocence: Like Burgundy, he seems to have the mentality of a small child.
• Big Little Brother: Unlike his older "siblings" Burgundy and Kelly who look like teenagers, Amber is a big and muscular man.
• The Brute: He's the strongest of "children" and towers over everyone, including Akim, outside of Akim's One-Winged Angel form.
• Dumb Muscle: Noted to not be particularly intelligent.
• Lightning Bruiser: Incredibly fast and strong. Nothing compared to Akim, however.
• Losing Your Head: Akim takes his head off when they "play" the same "game" Akim had him playing with Kelly earlier.

Kings of Makai

Wolf Daddy

Voiced by: Norio Wakamoto (Japanese), Richard Epcar (English)

Wolf's father and king of Makai.

---

• Disappeared Dad: He abandoned his son, left him on his own for years, and then orders him to bring his mother, who lives in the human world, to him, in a matter of a few days, without explanation.
• Gambit Roulette: He knew full well what Braz was up to, and let it happen to create a being powerful enough to stop Grimm's return. It succeeded, in the worst possible way.
• Good All Along: We're lead to believe Wolf Daddy is evil because he killed Staz's and Braz's father to take the throne for himself. It's eventually revealed in the manga that Wolf Daddy was never a bad guy. While he did kill Staz's father, he did it because Richardz was in danger of being corrupted by the real Big Bad, Herrshaft Grimm. He didn't tell Braz the truth because Braz's desire for revenge was a good motivation to create someone strong enough to defeat Grimm.
• Good Scars, Evil Scars: His face has several vertical scars on it.
• Light 'em Up: If he has to attack an opponent at range, he does so with giant spikes of light. Otherwise, he rips them apart with teeth, claws, and enormous brute strength.
• Lightning Bruiser: Very strong and very fast.
• Maou the Demon King: He's the current king of Makai, ruling over all the demons in that world.
• Mercy Kill: Unknown to Braz, this is the truth about Richardz's death. Richardz had absorbed Grimm's maryoku, but was unable to subsequently let it go, which put him in danger of falling under the possession and control of what remained of Grimm. Richardz asked Wolf Daddy to kill him, to prevent such a thing from happening. Wolf Daddy was reluctant, but did what needed to be done.
• The Usurper: He killed the former king of Makai, Richardz, and took the throne for himself. However, he didn't kill Richardz to steal the throne, but to save him from Grimm's possession.
• Voluntary Shapeshifting: He can change from man-form to wolf-form and back again at will.
• The Worf Effect: To show just how dangerous Akim is, Wolf Daddy gets taken apart with ease, and that's after spending numerous chapters showing just how strong Wolf Daddy is.

Richardz Blood

The father of Braz, Liz, and Staz. He was killed by Wolf Daddy ten years ago.

---

• Came Back Strong: By design. Braz used Akim to round up parts of the most powerful Mazoku, and give them to his father. Unfortunately, this allowed Akim to home in on Richardz and kill him, again.
• Creepy Shadowed Undereyes: He has dark circles under his eyes, same as his sons.
• Deceased Parents Are the Best: While Staz and Liz aren't shown to be that attached to him, Braz isn't embarrassed to sing his father's praises and witnessing his death affected him so badly that he spent the last ten years obsessively working on a plan to resurrect him.
• Disappeared Dad: He died when his three kids were young, killed by Wolf Daddy before he was fully possessed by Herrshaft Grimm.
• Eerie Pale-Skinned Brunette: Just like his sons, Richardz is a vampire with black hair and a pale skin tone that would suit an ill person.
• I Cannot Self-Terminate: Part of what sealed Grimm 10 years ago was Richardz absorbing part of his power, and he begged Wolf Daddy to kill him before it corrupted him and made him mad, like Grimm.
• Literal Change of Heart: Braz gives him Akim's heart to replace the one Wolf Daddy crushed. Unfortunately, the heart donor wasn't dead and soon reclaims his missing organ.
• Ludicrous Gibs: How Akim makes him die the second time.
• Posthumous Character: He has been dead for ten years by the time the story takes place, so nearly all information about him comes from flashbacks. We do see him alive for a few chapters after Braz resurrects him, but it doesn't last long because of Akim.
• Shipper on Deck: He's glad to hear Liz say Fuyumi is Staz's girlfriend and would like to see them together.
• Shoot the Dog: Stabs Braz and Staz with a magical knife to send them into a near-death state so they could learn the truth about Grimm, and "The Door."
• The Stoic: He never shows strong emotion and is quite collected.
• Vampire Monarch: He was the vampire king of Makai until he was killed by Wolf Daddy, who became the next king.
• Walking Spoiler: It's difficult to mention this character without spoiling the second half of the series.

Herrshaft Grimm

^{Click to see his transformation}

The first king of Makai. He was very greedy, and as a result, absorbed too much magical essence, which killed him.

---

• Ambition Is Evil: In his blind ambition to absorb as much demonic power as he could, he devoured countless demons. When even that wasn't enough to satisfy his greed, Grimm tried to channel all the flow of magical essence that came to the demon world from the human world. In the end, Grimm's body drowned in magical essence and what was left of his magical power combined with the power stored behind the Door of Magical Essence. The result is that Grimm transformed into a monster of magical essence.
• Big Bad: He's directly or indirectly responsible for all the bad things that happen in the series, from the deaths of the Blood siblings' parents to the creation of Akim. After completely taking over Akim's body and mind, Grimm officially becomes the main villain.
• Cannibalism Superpower: Since he lacked a natural draining ability like that of vampires, Grimm consumed the demonic power of other demons by eating them.
• Evil Overlord: He rose to become king of Makai by killing and devouring every strong demon he challenged. As king, he placed high taxes on his subjects to force them into giving him a piece of their demonic power. Those who tried to oppose him became his dinner.
• Eyes Do Not Belong There: His first form is a giant hand with eyes at the palm and fingertips.
• I Have Your Wife: During the Final Battle, Grimm takes Liz as hostage to use her as a bargaining chip in an attempt to force Braz into making a deal with him and give him back Akim's heart.
• Offing the Offspring: He mercilessly kills his "son" Amber.
• One-Winged Angel: During the Final Battle, he transforms into an Eldritch Abomination with multiple arms that looks like something out of a Lovecraftian story. Staz directly compares it to Neo Exdeath, the Final Boss of Final Fantasy V.
• Sealed Evil in a Can: He's trapped behind the Door of Magical Essence. Eventually, he escapes and his power is absorbed by Akim, making him Grimm's vessel.
• Spiky Hair: The picture of his original form shows him as a man with hair spiky like a porcupine. Akim gains this hairstyle shortly after assimilating Grimm's power.
• Truly Single Parent: Burgundy and Kelly were created from Akim's demonic power, but Amber was made from Grimm's.

Demon World Acropolis Police

Chief of Police Goyle

Voiced by: Daisuke Kishio (Japanese), Ben Pronsky (English)

The leading police officer in the Palacial district.

---

• Adaptation Dye-Job: In the manga, he has a pale skin tone. However, the anime made him dark-skinned.
• By-the-Book Cop: The first, and possibly only, police officer that actually follows a set of policies and procedures recognizable by a reader in modern society.
• Emotional Powers: His powerset is directly connected to his mood.
  • When he's angry, he summons a demon named Angry that is literally powered by his fury. The downside is that if his enemy manages to distract Goyle from his anger, Angry loses power.
  • When he's cool and calm, he becomes An Ice Person.
• Harmless Freezing: When using "Cool Head", the frozen target is not physically damaged in any way.
• An Ice Person: His ability "Cool Head" can be used to trap people in ice when they touch him.
• Pointy Ears: He's a demon with long, pointed ears.
• Sensor Character: His "Angry Spear" ability allows him to track down the target of his anger, even if he hasn't seen them before.
• Stoic Spectacles: He wears glasses and is usually a cool-headed type of character unless someone manages to piss him off.
• Summon Magic: When he gets seriously pissed off, Goyle vomits a little demon named Angry that is the literal embodiment of his fury and won't rest until it has killed the target of Goyle's anger.

Beros

Voiced by: Masumi Asano (Japanese), Julie Ann Taylor (English)

One of the two top officers of the Palacial area.

---

• Beware My Stinger Tail: She has a tail that ends with a snake's head, that has fangs and bites.
• Fashionable Asymmetry: One of the legs of her pants is shorter than the other.
• Female Rockers Play Bass: She is the Bassist for a Fake Band called "Evil Potato".
• Girlish Pigtails: She ties her hair up into twintails to show her Psychopathic Womanchild nature.
• Hair-Trigger Temper: She is frighteningly easy to piss off.
• Lady Swears-a-Lot: Her vocabulary is peppered with profanity.
• Oral Fixation: It's rare to see her without bubble-gum in her mouth.
• Psychopathic Womanchild: She is wildly immature and unstable, emotionally and mentally.
• Snipe Hunt: Thanks to going through Staz's manga collection trying to find some idea of Akim's weakness, seeing as several items from the manga do indeed exist in Makai, if somewhat different, she winds up dragging her superior along to find a magical bass capable of destroying Akim's connection to his magic. Amazingly, chapter 65 shows such a bass does indeed exist. But turns into a "Shaggy Dog" Story when everybody learns that the bass is just a replica based on the manga story.

The Hydras

Neyn Hydra

Voiced by: Kotono Mitsuishi (Japanese), Wendee Lee (English)

Bell and Knell's mother. Fourteen years ago, she merged with Fuyumi's human mother.

---

• Daddy Had a Good Reason for Abandoning You: After the Fusion Dance, she could not be together with her daughter for several very good reasons, not the least of which was that it was clearly not safe for Fuyumi and Bell to grow up together. At two years old, Bell opened a Black Curtain to Makai, which as was shown at the very beginning of the story, is a deadly dangerous place for Fuyumi. Further, as was also shown, simply being in the Human world drains Mazoku of their energy in a hurry simply for being there.
• Doppelmerger: She originally was two people; Fuyumi's human mother and Bell's demon mother. Because they were dopplegangers, they accidentally fused when they met each other.
• Duality Motif: She has heterochromia thanks to a Fusion Dance in her past.
• Half-Human Hybrid: She's the result of a Fusion Dance between Mazoku and Human dopplegangers.
• Locked into Strangeness: Her blue-green hair is the result of her Fusion Dance. When she was two separate people, her human self had black hair and her demon self had blonde hair.
• Love-Obstructing Parents: To horrifying levels. When she finds out that Fuyumi might have romantic feelings toward Staz and vice versa, she hires Professional Killers to try and kill him.
• Missing Mom: Fuyumi's human mother was merged with Bell's demon mother 14 years earlier. After debating on which family she would stay with, Neyn ended up with the Hydras and this forced her to leave Fuyumi with her father in the human world. Fuyumi never knew about any of this until she meets Neyn in the demon world.
• My Beloved Smother: None of her children have it in them to defy her. Once she knows Fuyumi is in Makai, she has Knell kidnap her and decides she'll keep Fuyumi with the Hydra family where Neyn can keep an eye on her. Neyn outright calls Fuyumi her property and claims she has every right to decide what's best for her daughter regardless of Fuyumi's wishes. Heads calls her out on it, reminding her that she long stopped being Fuyumi's mother and Fuyumi should be free to decide her own future.
• Never Gets Drunk: She spends an entire night having a drinking contest with Jack. Not only does she break her personal record, she's able to walk perfectly and hold back the urge to puke.
• Permafusion: She's the fusion of Fuyumi's human mother and Bell's demon mother. Since the fusion can't be undone, she had to leave her human husband and Fuyumi to live in the Demon World with her demon family.

Heads Hydra

Voiced by: Keiji Fujiwara (Japanese), Keith Silverstein (English)

The father of Nell and Bell.

---

• Abusive Dad: His idea of "grounding" Bell involved using spatial gates to dump her into a lake, deep underground, and having her swim to shore to an abandoned laboratory of some sort. He would be waiting on shore for her to "cool off."
• Dimensional Traveler: Bell and Knell inherited their ability to cross dimensions from him.
• It's All My Fault: He feels responsible for Fuyumi being turned into a ghost because Akim copied his teleportation powers which Akim later used to open the portal that lured Fuyumi into the demon world. He helps Staz take Fuyumi away from Neyn because he couldn't bear the guilt of taking more of Mr. Yanagi's family away from him.
• Our Hydras Are Different: He's a hydra demon.
• Shapeshifting Trickster: He drugs a "muffin" claiming that it's cursed to kill Staz if he breaks his word, and forces Staz to eat it in exchange for letting Staz and Fuyumi leave his realm... that Fuyumi was kidnapped to. And uses an action figure on a clearly hallucinating Staz to make him think the "curse" is real.
• Species Surname: His surname is Hydra and his true form is that of a giant three-headed dragon.
• Voluntary Shapeshifting: He can go from his Hydra form to his human form at will. It is yet to be seen if he can do the reverse.
• Weredragon: His true form is a giant, winged dragon with three heads, but he spends most of his time in a human form.

Knell Hydra

Voiced by: Yūki Kaji (Japanese), Erik Kimerer (English)

Bell's younger brother who was sent to kidnap Fuyumi by the orders of their mother Neyn.

---

• Butt-Monkey: Often subjected to very unlucky moments, particularly being kicked in the groin by his older sister. Even when he dodges Bell's kick, he trips and hits his groin against a railing.
• Cool Gate: He uses a white cloth as this.
• Family Theme Naming: Like his sister Bell, Knell's name ends in -ell.
• Long-Lost Relative: He happens to be Fuyumi's younger half-brother, although Knell had no idea he had more than one older sister until his mother sends him to kidnap Fuyumi.
• Nice Guy: Despite being ordered to kidnap Fuyumi, he happens to be a very friendly person at heart and ensures Fuyumi's safety and hospitality. His room behind his white cloth even resembles a living room.
• Non-Action Guy: Unlike most major males in the series, Knell doesn't have combat skills.
• Running Gag: Every time he and Bell are in a scene together, he's suffering groin damage.
• Shipper on Deck: While he likes to tease his sister, he truly wants to be supportive of Bell's crush on Staz. Although, he wonders if he should support Bell's love rival Fuyumi too since Fuyumi is also his big sister.
• Teleportation: He has similar teleportation powers to his sister Bell, but less powerful.
• Uneven Hybrid: Knell was born after the fusion of Neyn and her human Doppleganger, making him one-third human. Because of this, his teleportation powers aren't as strong as his full demon sister's.
• Younger Than He Looks: Knell looks like he's Staz and Wolf's age (he's as tall as them) but since he was born after the dopplegänger fusion 14 years ago, he must be 13 or 14.

Team Fearless

A squad of bounty hunters hired by Fuymi's "mother" Neyn to test Staz's resolve, by trying to kill him.

---

In General

• Bunny-Ears Lawyer: They are all quite odd, to put it mildly. Still they are noted to be quite competent in their field, and even had Staz on the ropes for a while.
• Explaining Your Powers to the Enemy: While fighting Staz, those with powers boasted, in exquisite detail, exactly how they work.
• Overrated and Underleveled: While quite dangerous, they're nowhere near as nasty as their reputation suggests. Staz is their first vampire hunt, despite them having a reputation as vampire slayers.
• Punch-Clock Villain: They are fairly affable if they don't have a contract out on you.
• Rag Tag Bunch Of Misfits: Just by looking, one would never think they'd work together, at all. Strangely, they do, and very well at that.
• Vampire Hunter: Subverted. Neyn hires them to kill Staz because of their reputation as vampire hunters. Actually, they haven't killed a single vampire yet; Siam calls himself and his team vampire hunters because it's cool.

Siam Kid

Voiced by: Noriaki Sugiyama (Japanese), Brian Beacock (English)

The leader, founder, and primary decision maker of the group.

---

• Ambiguously Brown: There seems to be no reason for him having dark skin other than his cat form having black fur.
• Animorphism: He is capable of transforming into a tuxedo cat.
• Cat Boy: He has various cat features such as the eyes and a tail.
• Chuunibyou: His imagination far exceeds the reality.
• Combat Clairvoyance: By eating a piece of his opponent's hair, Siam can foresee their movements in battle.
• Cute Little Fangs: He has feline fangs, as expected from a Cat Boy.
• Cuteness Proximity: Invoked. He can use his "housecat" form to lure his target by being overly cute. It worked on Fuyumi, but not on Staz.
• Dogged Nice Guy: He develops a crush on Akim's "child" Kelly and makes several attempts to win Kelly over such as doing magic tricks to impress Kelly.
• Expository Pronoun: He refers himself as "wagahai" in a Shout-Out to I Am a Cat.
• Gratuitous English: He often uses English lines in the original Japanese.
• The Leader: The members of Team Fearless are under his command.
• Leeroy Jenkins: When he has a target, he rushes out to face it with little thought. Fortunately, his team-mates are well aware of this, and are quick to provide backup.
• Love at First Sight: He instantly gets a crush on Akim's "child" Kelly when they first meet.
• O.O.C. Is Serious Business: His teammates notice something is wrong when he recommends caution in dealing with Akim instead of rashly going with the first plan off attack that comes to mind, even though that plan was a fairly reasonable one.
• Pointy-Haired Boss: While his Reader ability is very useful for battle, Siam is a pretty idiotic boss who puts a mission aside to flirt with the target's child, so his teammates have little respect for him and they do most of the actual work.
• Sharp-Dressed Man: He wears a tuxedo, possibly because his animal form is a tuxedo cat.
• Stalker with a Crush: When working as Akim's chef, Siam uses his free time to spy on Akim's "child" Kelly.
• Support Party Member: While he's nominally the leader of Team Fearless, he has no offensive powers and his Reader ability is used to let his teammates who can fight know the next move of their target so they can gain the advantage.
• Supreme Chef: He's a surprisingly good cook. This trait of his was instrumental in getting his crew to infiltrate the palace, and even Akim has nothing but praise for his culinary talents.

Samu

Voiced by: Takuya Kirimoto (Japanese), Matthew Mercer (English)

The swordsman for Team Fearless.

---

• Expository Pronoun: He refers to himself as "sessha", an archaic term meaning something like "Your humble servant". It's typical for samurai in anime/manga like Samu to use this pronoun.
• Eyepatch of Power: He wears an eyepatch over half his face.
• Eyes Always Shut: His eyes are always closed.
• Kryptonite Factor: He wields a silver sword which is instrumental in slowing the healing factor of regenerating beings, like vampires.
• Samurai Ponytail: He wears his hair in a high ponytail, giving him the look of a traditional samurai.
• Verbal Tic: He ends his sentences with " de gozaru".

Jasmine

Voiced by: Saeko Zougou (Japanese), Erica Mendez (English)

The lone female of Team Fearless.

---

• Anime Chinese Girl: Her character design is based on a Chinese Vampire and she has the "aru" Verbal Tic stereotypical of the trope.
• Hidden Eyes: The upper half of her face is always framed in shadow, but her eyes can be seen.
• Kryptonite Factor: Like Samu, the metal in her blades is also silver.
• McNinja: She's supposedly some kind of ninja.
• Nothing Up My Sleeve: She pulls out her Wolverine Claws from her sleeves.
• The Smurfette Principle: She's the only female on Team Fearless.
• Verbal Tic: She often ends her sentences with "aru".
• Wolverine Claws: She wears gauntlets with large metal blades, also made of silver.

Roi

Voiced by: Akira Ishida (Japanese), Todd Haberkorn (English)

The team strategist and mission coordinator.

---

• Awesome, but Impractical: His ability "chat room" allows him to communicate with her teammates in real-time, telepathically, regardless of distance, but he has to be asleep to use it.
• Dissonant Serenity: He seldom shows any strong emotion in combat. Justified as his ability requires being asleep, and strong emotions will wake you up.
• Mission Control: His "chat room" ability allows him to coordinate his team-mates attacks and actions.
• Sleepyhead: He dozes off frequently.
• Supering in Your Sleep: "Chat room" only works when he's asleep.
• Third Eye: He has three eyes, except the third one is attached to the top of his head instead of his forehead.

Rasodo

The biggest member of Team Fearless.

---

• Bandage Mummy: He's completely covered by bandages like a mummy.
• The Big Guy: He is the hardest hitter in Team Fearless.
• Bondage Is Bad: Has Fuyumi Bound and Gagged inside himself while his team was trying to kill Staz.
• Boom, Headshot!: On the receiving end of this from Fuyumi when she fired a gun from inside him.
• Did Not See That Coming: Like everyone else, he was dumbstruck that Fuyumi's "toy" guns could fire real bullets.
• Hyperspace Arsenal: Downplayed. He can hold people inside his hollow body.
• The Voiceless: He never speaks.

The Black List

A group of Mazoku so dangerous, their names are scratched from the public record.

---

In General

• Loner-Turned-Friend: Jack, Stein, and Mist were all alienated loners until they were recruited by Wolf Daddy to fight Akim. At first, none of them get along, but they gradually become friends, leading to a moving You Are Not Alone moment.
• Ragtag Bunch of Misfits: They're all outcasts in the Demon World and for their strong abilities, they're selected as a special force to save the Demon World from Akim/Grimm.

"Evil" Jack of Steel

A notorious serial killer so dangerous, entire cities would be evacuated if word spread that he was going to show up.

---

• Afraid of Their Own Strength: He's secretly terrified of the power his "Berserker Lurk" which makes him go in a murderous rampage until he gains back his consciousness.
• Anti-Magic: His "Berserker Lurk" is completely immune to, and destroys, the special power and magic of others.
• The Berserker: If he's ever cornered in battle, he automatically goes into a Nigh-Invulnerable "berserker mode" and immediately lashes out at the threat until the threat is dead, or so far away that it can no longer be sensed, like in another dimension.
• Blood Knight: A really dark take on the trope. He is always looking to fight strong opponents, and relishes fights to the death. When he doesn't find anyone worthy, he lets himself be locked away.
• Color-Coded Eyes: His eyes are dark purple to show that there's something "special" about him.
• Death Seeker: He is explicitly shown seeking the person who can kill him, and allowed himself to be locked away when it looked like such a person couldn't be found.
• The Dreaded: Before he let himself be locked away, entire cities, in Makai, would be evacuated when word got out that he was in the area.
• Extra Eyes: The crosses below his eyes, across the upper part of his chest and each on his shoulders are all eyes that open when he enters his "berserker mode".
• Freudian Excuse: He became a Serial Killer because his Berserker Lurk state gave him temporary lapse of insanity and would make him go on a killing spree until he regained consciousness. The only way Jack could feel in control was by making himself kill as many people as he could while he's in his right mind, hoping he'll get used to it and not feel pain when Berserker Lurk makes him kill again.
• In Vino Veritas: After spending an entire night in a drinking competition with Neyn, the usually tough and violent Jack becomes a sobbing mess as he admits to Mist of how terrified he really is of his Berserker Lurk making him a mindless killing machine.
• Obfuscating Insanity: He acts as a deranged killer who can think of nothing but fighting someone strong enough to kill him. After his drinking competition with Neyn, Jack admits to Mist that he's actually completely sane, but his Berserker Lurk Super Mode causes him to lose control of himself and kill everyone around him. Jack believed that the only way to cope with this was by killing as many people as he can while he's still in control of himself so he doesn't feel pain when his Berserker Lurk makes him kill more people.
• Odd Friendship: He becomes good friends with his fellow Black List member Mist, a levelheaded Nature Hero. After the final chapter, it's shown Jack is paying visits to Mist's forest.
• Sour Outside, Sad Inside: He wants to make everyone think he's nothing but a bloodthirsty homicidal maniac. When his truth self is brought out by too much alcohol, Jack is revealed to be an extremely depressed and lonely guy who has always lived afraid of his own power and how it made him kill people against his will.
• Sweet Tooth: Fuyumi mentions that Jack loves desserts, which no one would expect.
• Walking Shirtless Scene: He's always shirtless.
• White Hair, Black Heart: His hair is completely white and colorless. He's also the most dangerous Serial Killer in the Demon World.

Shteyn Doji

An Oni with a penchant for singing.

---

• Afraid of Their Own Strength: His singing can make other monsters pass out, making him so afraid of himself that he secluded himself in the mountains where no one could hear him sing.
• Battle Strip: He takes off his shirt when he enters his Super Mode.
• Brown Note: It's said that his singing caused everyone in his Oni gang to be knocked out.
• Elvis Impersonator: He's like an Oni fanboy of Elvis.
• Eyes Always Shut: He normally keeps his eyes closed.
• The Hermit: He isolated himself in the mountains to sing alone so people won't get hurt by his destructive voice.
• Horned Humanoid: As an Oni, he has a pair of horns on the sides of his head.
• I Am Not Left-Handed: Invoked. He has to hold back sparring with Jack because he knows if he goes all out, "Berserk Jack" would kill him.
• Love at First Sight: He falls for Beros the moment he first meets her, wanting to sing for her "from the bottom of his heart".
• Make Some Noise: He can transmit his emotions to those who hear him sing. At first, he accidentally hurts people with his singing because of his anxiety, but when he transmits positive emotions, his singing is harmless.
• Meaningful Name: He gets his name from Shuten Doji, a famous Oni in Japanese folklore.
• Oni: He's an Oni who looks like a large man with horns on the sides of his forehead. He doesn't match the folklore since he looks like an Elvis Impersonator.
• Power Incontinence: At first, his singing voice knocks people out against his will. Once he finds out his singing's effect is tied into his emotions, he can control it properly.

Elafores Mist

An elf that maintains and protects the forests and wilderness of Makai.

---

• Bow and Sword in Accord: He's both a swordsman and an archer.
• The Confidant: Jack's drunkenness makes him talk sincerely about his fear of his Berserker Lurk mode and how he doesn't really want to kill people even though he feels he has to do it to not feel pain. Mist listens to Jack's troubles and gives him a much-needed hug while telling him he believes Jack can gain control over his power and won't kill him.
• Deer in the Headlights: He freezes up in terror as he witnesses Grimm going into his One-Winged Angel form.
• Dude Looks Like a Lady: He had to point out he's a guy when Jack called him "Miss."
• Elfeminate: A pretty elf guy who's very easy to confuse for a girl.
• The Empath: He can sense the thoughts and feelings of others.
• Friend to All Living Things: Quite literally. He calls the wild animals his friends.
• Inconsistent Coloring: His first color page of the manga showed him with cyan hair and pink eyes. Later, color covers depict him with white hair and yellow eyes.
• The Leader: He's appointed as the leader of Black List.
• Nature Hero: He only fights for the sake of protecting the forests and wildlife.
• Nature Lover: He loves the wilderness and its animals.
• Odd Friendship: He becomes surprisingly good friends with his fellow Black List member, the infamous Serial Killer Jack. After seeing a glance of drunk Jack's true vulnerable self, Mist understands he isn't a deranged murderer, but a lonely and scared guy in desperate need for a friend. Mist decides to give him exactly that.
• Only Sane Man: Of the Black List group, he's the most level-headed. That's why Wolf Daddy wants him to keep Jack and Doji in line.
• Our Elves Are Different: Not depicted as the haughty racist bastard that most elves in fiction seem to be.
• Pointy Ears: He has long, pointed as elves typically do.

Little Patty Jabberwocky

^{Click to see his Jabberwocky form}

The fourth and final (secret) member of the Black list. He runs a small farm at a mountain range near the capital.

---

• Befriending the Enemy: He decides to befriend Akim's "daughter" Burgundy in hopes she'll switch sides so he and White Step don't have to fight her, but White Step thinks Patty is too naive to understand Burgundy is just a monster that needs to be killed. In the end, however, Patty's plan to befriend Burgundy succeeds.
• Beware the Nice Ones: He's a kind and sweet boy, but mess with his friends or do something evil to piss him off and he'll turn into a furious monster.
• Cheerful Child: He's a sweet, sensitive and happy young child.
• Declaration of Protection: To Burgundy, after rescuing her from Wolf and Staz. Unfortunately, he's unaware that she's the one who started the fight, and attacked them first.
• Friend to All Living Things: He has several animals on his farm that he sees as friends.
• Kaiju: His monster form is big enough to swallow Burgundy whole.
• Locked Out of the Loop: He doesn't know anything about what's going on in the rest of Makai, and everyone would have wanted to keep it that way, if it weren't for Akim setting up a gladiatorial arena in the same mountain rage as his home, and having Burgundy literally drop in on him.
• Nice Guy: Everyone agrees that he's exceptionally meek and mild.
• Partial Transformation: Thanks to now having full control over his monster transformation, Patty can stay in a mostly humanoid shape while he grows demon wings and a tail to fly in the battlefield. He can also transform only his arms into monster size to attack Grimm.
• Retired Monster: He has a form of a depraved bloodthirsty beast. Thanks to White Step, this has been suppressed, taking him off the black list, and giving him a hard-earned somewhat "normal" life.
• Save the Villain: He interrupts Staz's and Wolf's fight against Burgundy to save her and takes her to a safe place by carrying her in the mouth of his monster form.
• Scary Teeth: When he transforms, his teeth get long, sharp, and very pointy.
• Sent Into Hiding: White Step asked Wolf Daddy to not let Akim know about Patty's existence because he didn't want Patty to get involved in the fight when the boy can finally live in peace at the mountains after suppressing his monster form. It doesn't work because Patty ends up befriending Akim's "daughter" Burgundy and the boy chooses to help taking down Akim/Grimm.
• Shapeshifter Baggage: His transformation involves a significant change of mass, and there's yet to be an explanation for this.
• Voluntary Shapeshifting: He can turn into a giant monster. It used to be involuntary, but he now has full control over his transformation.
• You Wouldn't Like Me When I'm Angry!: Pissing him off, which isn't easy, makes him shapeshift into a very large, winged, and near-unstoppable beast.
• Youthful Freckles: He has freckles on his face, showing his friendly and childlike personality.

Other Characters

Mr. Yanagi

Voiced by: Eiichiro Tokumoto (JP), Matthew Mercer (EN)

Fuyumi's father.

---

• Good Parents: Heads considers Yanagi the most dreadful man he has ever met because Yanagi let Heads take his wife away from him for the sake of his daughter's safety and future.
• I Want My Beloved to Be Happy: Played with. After his wife fused with Heads' wife, Yanagi gave her up not because of her happiness but Fuyumi's since his daughter couldn't have a normal life with a Half-Human Hybrid mother and a half-sister with teleportation magic. Yanagi did make Heads swear that if he didn't make Neyn happy, he would never forgive him.
• Unnamed Parent: His given name is never mentioned; he's only called "Yanagi" or "Fuyumi's father".

Katy

Wolf's mother who abandoned him. She lives in Japan, where she works as an English teacher.

---

• Cool Big Sis: She takes this role for Bell, acting as a laid-back big sister who listens to her unrequited love troubles and playfully teases her while at it.
• Former Teen Rebel: From what we see in her old picture, she was a gang member in her youth before settling down in the human world to work as a teacher.
• Missing Mom: She abandoned Wolf when he was a baby and he didn't even know she was still alive until his father sent him to meet her in the human world.
• Retired Badass: It's implied she was a powerful fighter in her youth, but now she has been retired for years and lost nearly all her demonic power as a result of living in the human world for so long.

White Step

An old colleague of Wolf Daddy who worked together with him in a secret task force called the Demon Colors under the king. He is a human who has survived in the demon world using his dodging skills and living off the grid.

---

• Badass Normal: He's an old human man with no natural demonic powers, yet he's a tough fighter who can land good hits on Artificial Zombies, a vampire, and a werewolf.
• Eyes Always Shut: He's generally depicted with his eyes closed.
• Mentor Archetype: He trains Staz and Wolf in the art of dodging.
• Old Master: He's an old man who was once part of the secret forces of the Makai king. While he's completely human, White Step has trained himself arduously every day to survive in the demon world and mastered the art of predicting his opponent's attacks so he can go toe-to-toe with demons.
• Weak, but Skilled: White Step is human and has no magical powers like demons. He makes up for it with rigorous training and learning to read his opponents.

Kiji & Tobi

Tobi (left) and Kiji (right)

Voiced by: Shusaku Shirakawa (JP), Matthew Mercer (EN) [Kiji]; Kenji Roa (JP), Todd Haberkorn (EN) [Tobi]

Wolf’s henchmen.

---

• Crouching Moron, Hidden Badass: Implied. We never see either of them in action (Tobi himself is a little klutzy), but when Wolf sends them off as the new leaders of his gang, he notes that they are the strongest members after him.
• Desperately Craves Affection: Tobi tries really hard to impress Wolf. He doesn’t succeed much.
• Put on a Bus: They gets sent off to lead Wolf’s gang around Chapter 8. Tobi even lampshades if they will ever get any more screen time after that.
• Straight Man and Wise Guy: Kiji is the Straight Man to Tobi’s Wise Guy.
• Those Two Guys: They're always seen together and don't do much besides banging out with Wold early on.
