The cast of Violinist of Hameln.
The main protagonist. A mysterious man who wields a super-sized violin with magical powers. Contrary to his elegant appearance, he is a rude, obnoxious moron who will take advantage of his friends for profit and amusement at every chance he gets. However, there's much more to him than meets the eye. We later learn that he is the son of Demon King Chestra and Pandora, the woman who unleashed demons upon the world. His main goal is to prevent his father's resurrection and rid the world of all Mazoku.
- Adaptation Personality Change: In the anime he's a straight up brooding Warrior Poet with no real quirks.
- Affectionate Nickname: Raiel calls him "Ha-chan" most of the time, and has since they were kids. Flute tries to call him "Ham-chan" briefly, but he's so utterly disgusted by it that she stops soon after.
- All of the Other Reindeer: He was ostracized and persecuted for being part Mazoku his entire life.
- Ambiguously Bi: Despite constantly mocking Raiel for how girly he is, he's noted to get nosebleeds whenever seeing him naked and at one point claims that he's prettier than Flute. Compared to the Camp Straight Raiel who never shows any interest in Hamel beyond Undying Loyalty, Hamel's sexuality starts coming into question.
- Anti-Hero: A type V at the beginning, but grows into something in between a IV and III by the end.
- Anti Anti Christ: Wants nothing to do with the Mazoku and his father and would rather disregard his Mazoku heritage altogether.
- The Atoner: Shown multiple times to regret all of the lives he took while in Mazoku form. Particularly Raiel's parents.
- Badass Cape: His cape is really nice.
- Bad Powers, Good People: Wields the Demon King’s power, which everyone agrees that can only cause death and destruction. Later in the series, he gains some control on this power and starts channeling it to fight other Mazoku.
- Bash Brothers: With Raiel, with whom he forms a musical duo.
- Beneath the Mask: Hamel's Jerkass behavior is a front he puts up to avoid getting close to others. Deep down he's an incredibly compassionate and noble person.
- Berserk Button: Harming Flute or his mother is a good way to get yourself killed.
- Later in the manga, he flips out at the suggestion he might be similar to Chestra.
- Best Friends-in-Law: Becomes this with Raiel during the epilogue after he marries Sizer.
- Big Brother Mentor: To Trom... when he feels like it.
- Break Her Heart to Save Her: Sends Flute away rather cruelly, because he's afraid she'll end up being killed by his Mazoku side. With the help of The Power of Trust, they reunite stronger than ever.
- Brother–Sister Incest: A very light example with Sizer, who he makes wear revealing outfits as soon as they become allies, as well as frequently expressing his joy over finally having a sexy woman on the team. Flute is still weirded out by it.
- Brother–Sister Team: Grows into one with Sizer, though it takes time to happen.
- Brooding Boy, Gentle Girl: His relationship with Flute swings between this and Belligerent Sexual Tension, depending on if it's a comedic or serious scene.
- Calling the Old Man Out: When finally confronting Chestra, Hamel throws all his (completely justified) hate for him in his face. Chestra couldn't care less - in fact, he thinks it's hilarious and mockingly completes Hamel's rant.
- Cannot Spit It Out: He absolutely refuses to acknowledge his feelings for Flute. This is actually more out of fear of hurting her than him just being a jerk.
- Cast from Lifespan: His body-controlling song makes its target a devastating fighter that can easily overpower a Mazoku in combat regardless of how weak they normally are, at the cost of taking years off their life. As Hamel himself isn't affected by these side effects, though, he couldn't care less and uses it with impunity. This predictably horrifies Flute, who he uses the song on several times before revealing its drawbacks to her.
- Character Development: After he transforms into a Mazoku for the first time he becomes significantly less of an asshole and much more open with his feelings. This actually gets Played for Laughs immediately after it happens, as Hamel's random transformation into a shining beacon of goodness confuses his teammates to no end.
- Chick Magnet: His good looks and reputation draw the ladies in... and his awful personality scares them off not long after.
- Chivalrous Pervert: "Chivalrous" may be too kind of a word for him, but he's both incredibly heroic and lecherous, to the point where he's overjoyed at the prospect of the manga becoming a hentai.
- Crouching Moron, Hidden Badass: A bumbling Jerkass one minute, an absolute badass the next. Sometimes these two states aren't mutually exclusive.
- Cordon Bleugh Chef: He’s a great cook, but it’s best not to ask about the ingredients. You may find out it’s giant earthworm. He also attempted to cook Poseidon at some point.
- Supreme Chef: As stated above, while his ingredients are dubious (monkey brains, for instance), his food is apparently incredible.
- Dark and Troubled Past: He was persecuted for being a Mazoku for most of his childhood and his mom, one of the few people to defend him, was kidnapped when he was still a kid. Not long after, he unleashed his Mazoku powers for the first time and proceeded to kill everybody else, including the only other people who defended him. He is clearly still affected by these events.
- Dark Is Not Evil: Although it is a huge jerk.
- Destructive Savior: He tends to cause just as much damage as the Mazoku do, sometimes more.
- Defrosting Ice King: Starts out horrendously abusive towards Flute and yet ends up caring just as much about her as he does for Pandora.
- Determinator: Late in the story Oboe realizes that he's been suppressing his Mazoku form through willpower alone.
- Dirty Coward: Isn’t the least bit ashamed to turn tail when the enemy seems like too much work. However, this is strictly Played for Laughs - when the scene turns serious, Hamel is very heroic and would never let innocents get hurt if he can help it.
- Disturbed Doves: Parodied. He's first introduced being surrounded by doves... and then promptly starts eating them!
- Elegant Classical Musician: A male example. No matter how big of a jerk he is, people always find themselves deeply moved when he plays the violin. He learned it from his mother, who was also this trope.
- 11th-Hour Superpower: Two. First, he unleashes his full Mazoku form after drinking some of Chestra's blood during their duel, and then he sprouts angel wings when delivering the final blow to Chestra.
- Emotion Bomb: Can manipulate emotions with magical music.
- Evil Makes You Ugly: His full Mazoku form is incredibly demonic and hideous, but manages to retain Hamel's beautiful, glistening eyes.
- Face of an Angel, Mind of a Demon: In the very first chapter Viola is so stunned by his otherworldly beauty that he starts to wonder if he's god. Moments later, Hamel starts brutally eating all of the doves that flocked around him to hear him play. And it all goes downhill from that.
- Female Angel, Male Demon: Despite having both angel and Mazoku blood, he is only ever shown having the attributes of a Mazoku, in contrast to Sizer. This is explained by his Mazoku blood being dominant over his angel blood. He finally accesses his angel form when dealing the finishing blow to Chestra.
- Freudian Excuse: He and his mother were ostracized and harassed by their community constantly when he was young until he lost control of his Mazoku blood and killed them all to defend himself and his mother was later taken from him by the Mazoku, leaving him alone beyond Oboe. His Mazoku blood also makes it incredibly hard for him to completely understand humans, despite his unconditional love for them, making him become an emotionally closed off person.
- Glass Cannon: His full Mazoku form is on par with Chestra in power, however he lacks Chestra's limitless magic power and thus exhausts most of it, and with it his life force, after a short while.
- Good Is Not Nice: He's such a bastard that he can be mistaken for one of the bad guys, especially early on.
- Grievous Harm with a Body: One of his favorite tactics is throwing his less-than-willing friends at enemies.
- Hair of Gold, Heart of Gold: At first averted, but proven to be played straight by the end.
- Half-Breed Discrimination: As a child, he was abused and persecuted by humans for being half Mazoku. Even after becoming a famous hero, some people still mistrust him. Chestra mocks him for being half human, saying that it makes him weak. Interestingly, Sizer never gets flack from humans even though she's clearly not entirely human - probably because her wings mark her as an angel rather than a Mazoku.
- Half-Human Hybrid: He's half human and half Mazoku. He's actually only a quarter human. The other quarter? Angel.
- Half-Identical Twins: He and Sizer are incredibly similar looking.
- The Hero: At first he's about as far down the Anti-Hero scale as you can be without becoming an outright villain, but he grows to fit the role better later on.
- Heroic BSoD: Goes through a huge one when Orgel accuses him of hiding his Mazoku nature.
- Heroic Comedic Sociopath: Humanity’s hope is also a thief and a liar who charges outrageous sums of money from the people he saves, abuses his powers any chance he has and likes to abuse his friends for fun.
- Heroic Sacrifice: Narrowly averted. He becomes a full Mazoku to kill his father and is about to take the Demon King's throne for himself to prevent the Mazoku from ever attacking humanity again, but manages to find a way to work around it at the last minute.
- Heterosexual Life-Partners: With Raiel, his first, and for most of his life only, friend.
- Hidden Depths: Beneath his extremely Jerkass exterior lies a person who has spent so long being called a monster that he himself has come to believe he is one and goes to great lengths to make those he cares about hate him to avoid getting close to them. Hamel's true personality is actually that of a quiet, brooding Warrior Poet.
- Hide Your Otherness: Wears a hat at all times to hide this Mazoku horn. He even wears it when he's alone/with only his friends around, indicating just how much he hates his Mazoku side. When he transforms into a full Mazoku, he can't bear the thought of Flute seeing what he's become, and he's so distressed he rips out a horn and a wing.
- Horned Humanoid: His hat hides a single Mazoku horn. He gains two much larger ones in his Mazoku form.
- Hot-Blooded: Until he gets serious.
- Hunter of His Own Kind: A half Mazoku who rejects his demonic heritage altogether and fights on the humans’ side.
- Hypocrite: Very much so. For example, he relentlessly mocks Clari for his girly appearance while he is just as Bishōnen himself.
- Hypocritical Humor: He often rants to his foes about hurting his friends when he spends much of his time doing just that.
- I Am Not My Father: His primary goal in the later parts of the manga is to avoid taking the Demon King's throne for himself and becoming just like Chestra.
- I Just Want to Have Friends: After having spent most of his life being treated as a monster, Hamel desires kindness and companionship above all else. However, his own intense self loathing prevents him from admitting it and actually causes him to actively push his friends away.
- Inferiority Superiority Complex: Talks a big game but actually considers himself to be a monster and is just as willing to sacrifice himself for humanity's sake as he is to defeat the Mazoku.
- Instrument of Murder: Later in the series, Olin "upgrades" his violin to install cluster missiles, a laser cannon, a drill and a jet engine. It's mostly Played for Laughs, but is also used as a plot point when he uses it to cross the continent in an instant to help his friends.
- Jerkass: His defining characteristics initially are his pettiness, massive ego and frequent abuse towards his teammates.
- Jerk with a Heart of Gold: He's always this, though it becomes more pronounced later on, particularly after he first becomes a Mazoku.
- Lack of Empathy: One of his biggest problems comes from this. His human flesh gives him an inherent sense of good and kindness, but his Mazoku blood gives him a drive to cause chaos and suffering. It isn't that he doesn't want to do good, but that he is actually incapable of truly understanding how to be good. He is shown to be aware of this, which provides a great deal of stress for him.
- Leitmotif: Ode to Joy, which doesn't initially appear to fit him at all but perfectly matches his desire for rebirth and to be accepted by humanity.
- Let's Get Dangerous!: When the fight gets serious, Hamel instantly becomes an incredibly focused and stoic warrior.
- Lightning Bruiser: When he unleashes his Mazoku power he skyrockets to being significantly stronger than Vocal, who had previously curbstomped most of the cast.
- Love Martyr: Toward all of humanity.
- Mad Scientist's Beautiful Daughter: Genderflipped to Evil Overlord's Hot Son. Though he's quite a jerk himself, he's much, much better than his father.
- Mama's Boy: Justified in that his mother was one of the very few people who ever showed him kindness.
- Meaningful Name: Named after the classic fairy tale of the Pied Piper of Hameln, who was shunned by the villagers despite his good deeds and turned to villainy as a result.
- Mind-Control Music: Played with. He can’t actually mind control people, only enhance feelings that were already there.
- Mistaken for Gay: He and Raiel are mistaken as a gay couple at one point after sharing a kiss.
- Mr. Vice Guy: He's obsessed with money, steals people's stuff to sell them in a pawn shop only to spend the money on alcohol and gambling, and likes to put his friends in horribly embarrassing costumes.
- Musical Assassin: His weapon of choice is a cello-sized violin that can play magical melodies.
- Next Tier Power-Up: Parodied somewhat with the upgrades Olin gives to his violin, which for the most part are all completely useless and only make using it harder for Hamel, to the point where he removes them all pretty much immediately. Played straighter with his Mazoku form, which he first uses roughly midway through the story and continues to rely on more and more as the series goes on.
- Non P.O.V. Protagonist: He is the main character, yet the story is almost never told through his eyes and we get to see his thoughts very rarely. His thoughts and motives are usually explained by Oboe, his adoptive father and the person who knows him better than anyone, and Raiel, his childhood friend who is incredibly understanding and empathic.
- Obfuscating Stupidity: He's not nearly as big of a moron as he seems. Sometimes though, he's not nearly as smart as he seems, though this is always Played for Laughs.
- Official Couple: With Flute in the end.
- O.O.C. Is Serious Business: After Orgel claims he's no different from any other Mazoku, he suddenly becomes incredibly quiet and serious. He sticks that way for a while before finally getting over it.
- Parental Favoritism: Sizer initially believes this was the case with Pandora, though it's made clear she loved both of them equally. Chestra, however, does seem to favor Hamel over Sizer, though this is more because his more dominant Mazoku blood would make him a superior heir rather than any sort of love for him.
- People Puppets: Another use of his magical music. Flute is his favored target.
- Perpetual Frowner: When he isn't giving a Slasher Smile, his default expression is almost always an annoyed frown. The number of times he gives a genuine smile can be counted on one hand.
- Polar Opposite Twins: With Sizer.
- Pretty Boy: He's outright described in the first chapter as beautiful. The contrast between his shoujo-style appearance and his horrendous personality is a constant source of humor.
- Quirky Bard: An odd protagonist example. While Hamel is a capable melee fighter, and begins to rely more and more on his own power rather than the violin's later into the story, his main role in battle is to play his violin to enhance the feelings and powers of those around him.
- Red Oni, Blue Oni: The red to both Raiel and Sizer's blue.
- Rule of Funny: Whether he's a solemn, brooding loner or an over the top loud-mouthed Jerkass Large Ham depends entirely on this.
- Running Gag: Whenever he comes up with a plan, it always involves wearing elaborate animal costumes regardless of the context. Dressing Flute up in various humiliating animal suits even becomes one of the primary mechanics in the video game.
- Roaring Rampage of Revenge: Used against him when Guitar tricks him into thinking he killed Pandora to unleash his Mazoku form.
- Screw Destiny: As the Demon King's son and heir, his destiny is to give in to his Mazoku blood. He spends the entire series struggling against it and succeeds in changing his fate.
- Sensitive Guy and Manly Man: Manly man to Raiel's sensitive guy.
- Next Tier Power-Up: Parodied somewhat with the upgrades Olin gives to his violin, which for the most part are all completely useless and only make using it harder for Hamel, to the point where he removes them all pretty much immediately. Played straighter with his Mazoku form, which he first uses roughly midway through the story and continues to rely on more and more as the series goes on.
- Slap-Slap-Kiss: His relationship with Flute is all about this. He's actively trying to stop her from loving him.
- The Stoic: When he gets serious, Hamel tends to be completely stone faced. This is implied to be his true personality.
- Sour Outside, Sad Inside: His abrasive personality hides emotional pain and self loathing. He drives people away because he's terrified of unleashing his Mazoku side and hurting them.
- Superpowered Evil Side: His Mazoku form.
- Tragic Keepsake: His violin belonged to his mother Pandora before she was taken by the Mazoku.
- Traumatic Superpower Awakening: His Mazoku power is unleashed when he’s extremely upset.
- Token Evil Teammate: Despite also being The Hero.
- Took a Level in Kindness: After the party defeats Orgel he starts to become a more consistently better person, although it's actually played for laughs initially where he becomes too nice. After he reverts mostly back to his old self, he's still shown to have become a much nicer guy, though considering how much of a asshole he was before, that isn't really saying too much.
- Tsundere: He's more of the tsundere than Flute in their relationship, being incredibly mean to her most of the time before letting it slip out that he likes her.
- Unsympathetic Comedy Protagonist: He tends to only be unsympathetic during the comedic parts of the series.
- Used to Be a Sweet Kid: As a kid, he was friendly and smiled a lot. Then the Anthem massacre happened.
- Vitriolic Best Buds: With Flute, Raiel and just about everybody who isn't his enemy.
- Warring Natures: His human side and Mazoku side are in constant conflict. He identifies as human and tries very hard to keep the Mazoku's murderous nature under control. It turns out that the constant struggle increases his magical power.
- Winged Humanoid: Gains demonic black wings in his Mazoku form and angelic white wings in his angel form.
- With Friends Like These...: He's incredibly likely to beat you up, use you as a weapon and dress you up in humiliating costumes if you're his ally.
The main heroine of the story. A Plucky Girl from the small town of Staccato who follows Hamel as payment for saving the town from Mazoku. She later learns that she's the missing Princess of the Kingdom of Sforzando and capable of using incredibly powerful white magic. She's incredibly unlucky and tends to be the butt of many jokes, but is also an incredibly kind and compassionate person capable of warming the heart of even Hamel.
- Adaptation Personality Change: Not as much as Hamel, but she's much more demure in the anime.
- Assist Character: Follows Hamel around during every level in the video game and can be used as a weapon, a platform, a meat shield or dressed up in a variety of ridiculous animal costumes, each of which has a special ability to help traverse levels or find secret areas.
- Beautiful All Along: While cute-but-plain with her hair in braids, she's absolutely gorgeous with it down.
- Big Damn Heroes: Comes in at the last moment during the final battle to heal the entire party and give Hamel his violin.
- Born Unlucky: Played for both laughs and drama.
- Brooding Boy, Gentle Girl: Her relationship with Hamel swings between this and Belligerent Sexual Tension, depending if it's a comedic or serious scenes.
- Butt-Monkey: Easily one of the biggest ones in the series. She's beaten up and humiliated on a regular basis, generally by Hamel, and even declares herself "The most pathetic heroine ever."
- She's also forced to dress up in animal costumes more than any other character.
- Cast From Hitpoints: All of her healing magic drains her own life force.
- Cool Big Sis: Towards Trom. He even calls her 'Big Sister" a few times.
- Cool-Down Hug: Gives Hamel one after he turns into a Mazoku for the first time. While impaled.
- Cosmic Plaything: The universe seems to be out to get her. While usually played for laughs, it does lead to some pretty depressing moments.
- Cross Attack: When she's angry, she pulls out huge, mallet-sized crosses to beat down on the object of her ire.
- Determinator:
- While she herself has no fighting ability, she can take a very heavy beating during battle and still stand her ground.
- She'll never give up on Hamel. Never. No matter how awful he is to her, she'll keep trying to make him open up to her.
- Damsel in Distress: A frequent kidnapping target by the Mazoku due to her possessing the key to Pandora's box. Once she no longer has it, they stop trying to capture her.
- Damsel out of Distress: She usually wrangles herself out of her kidnapper's clutches.
- Forced Transformation: Spends an extended amount of time transformed into a cow after Cornet casts a spell on her.
- Friend to All Living Things: Though whether or not the living things are friends back depends on the mood of the scene.
- Healing Magic: Powerful enough to resurrect the recently deceased! Though it drains her own life force whenever she uses it.
- The Heart: Stated multiple times to be the emotional center of the team. Sizer and Oboe kick her out of her Heroic BSoD when they explain how she is the sole stabilizing factor of the party and without her, they'd be incapable of accomplishing what they had. Considering she's one of the main reasons for Hamel, Sizer and Trom's Character Development into better people, this is completely true.
- Heroic BSoD: Shortly after Hamel has his, Flute begins to freak out over the fact that she's useless to the team. Sizer and Oboe manage to kick her out of it.
- Hollywood Homely: Hamel frequently mocks her for her lack of sex appeal, and while she does dress fairly plainly, she's definitely not ugly.
- Incorruptible Pure Pureness: Incapable of letting any of the horrible abuse the universe throws at her making her give up. Her soul is considered pure enough to power the Daimou Sword.
- Living Emotional Crutch: Eventually becomes one for Hamel, as she's the only person who can stop him from fully turning into a Mazoku.
- Let's Get Dangerous!:
- She slaps Vocal multiple times and he reacts in pain from them!
- She summons an almighty goddess with some help from her mother.
- Letting Her Hair Down: When Flute lets her hair down, even Hamel is stunned.
- Love Martyr: Willing to go to insane lengths for Hamel, who begins outwardly showing his love for her very gradually.
- Made of Iron: Takes endless amounts of physical abuse and yet remains perfectly fine. It actually helps her out during dramatic moments, where it allows her to survive things that would kill normal people. She took getting her throat impaled by Mazoku!Hamel with a smile!
- Memento Macguffin: Her cross pendant is the key to Pandora's box.
- Mind Reading: She can see a person's thoughts when she uses her powers to heal them.
- Dirty Mind-Reading: While healing Raiel from a deadly nosebleed, she got a peek into his Sizer-inspired fantasies, leading her to state that suddenly she doesn't feel like saving him.
- Musical Theme Naming: She's named after an instrument.
- Neutral Female: While in possession of both powerful magic and great physical strength, Flute has no combat training and thus sits out of most battles. Later on she starts to hate her status as this as she begins feeling like The Load.
- Official Couple: With Hamel in the end.
- Only Sane Man: She, alongside Oboe, frequently points out just how absurd the world around her is, though even she has her moments.
- Pimped-Out Dress: Her princess attire features one. Later, Vocal makes her wear one after he kidnaps her.
- Plucky Girl: Incredibly plucky. She puts up with things that would either kill or psychologically destroy most people.
- The Power of Love: She taught both Hamel and Sizer the meaning of love, which proves key in helping them escape their Mazoku blood.
- The Power of Trust: The trust between her and Hamel is the only thing that can turn him back from Mazoku to human. Oboe outright states that her ability to trust others is her greatest strength.
- Princesses Prefer Pink: Both her everyday outfit and princess outfit are pink.
- Really Royalty Reveal: We learn she's the long lost princess of Sforzando fairly early into the story.
- The Rival: To Cornet for Hamel's affections.
- Slap-Slap-Kiss: Her relationship with Hamel. She's willing to put up with the constant fighting for the rare moments of genuine romance.
- Squishy Wizard: Humorously subverted. She's the party's token White Magician Girl, but she has little to no control of her magic for most of the series and instead possesses an incredibly sturdy body and Super-Strength.
- Strong, but Unskilled: Her training gave her super strength, but her lack of fighting ability still puts the rest of the team miles ahead of her.
- Stylish Sunhats: In both the manga and anime, she wears a crimson-pink sunhat with a white bow.
- Super-Strength: Gains some after her Training from Hell. This wasn't the intention of the training, but it happened anyway.
- Supporting Protagonist: Particularly early on, where the story is told mostly from her perspective.
- Team Mom: Shown to care for and look after every single member of the team at one point or another.
- Tomboy and Girly Girl: The girly girl to Sizer's tomboy because of her Team Mom status and more feminine clothing choices.
- Tomboy Princess: It helps that she didn't know she was a princess until she was a teenager.
- Took a Level in Badass: Her training from Cornet didn't help her magic at all, but it did give her superhuman strength that allows her to hurt even Mazoku.
- Training from Hell: Cornet puts her through some of this to strengthen her magic. Zigzagged in that he doesn't help her magic at all and was only meant to screw with her anyway but in the end it is grants her Super-Strength.
- Tsundere: A type B towards Hamel.
- White Magician Girl: Though she's noticeably more feisty and tomboyish than most examples, her magic is still in healing and supporting.
Hamel's best friend and foil. The self-proclaimed "Warrior of Love" who travels the world defeating Mazoku with his magical piano. While initially out to kill Hamel as revenge for supposedly slaughtering his entire village, Flute manages to convince them to bury the hatchet and return to being friends. He's incredibly kind-if scatterbrained, but has the unfortunate tendency to suffer nosebleeds from seeing anything remotely "feminine". He falls in love with Sizer the moment he sees her and devotes quite a bit of time trying to woo her.
- Affectionate Nickname: Hamel calls him "Rai-chan".
- Assist Character: During the final battle of the video game, he plays his piano to launch fire at Sizer to slow her down and make it easier for Hamel to hit her.

- Best Friends-in-Law: Becomes this with Hamel during the epilogue after he marries Sizer.
- Beta Couple: With Sizer, though their relationship doesn't really progress any faster than Hamel and Flute's, it's a lot less violent. They also hook up before they do.
- Big Brother Mentor: A more consistent example towards Trom, though even he takes advantage of Raiel.
- Big Damn Heroes: The most likely person to pull this off.
- Birds of a Feather: Gets along well with Flute due to their similar personalities.
- Born Unlucky: Raiel tends to get screwed over in just about everything he does.
- Bully Hunter: Always protected Hamel (and Pandora) when they were kids.
- Butt-Monkey: One of the few characters comparable to Flute in this department, maybe even surpassing her.
- How much of a Butt Monkey is he? Even Pandora hates him!
- Camp Straight: Obsessed with love and his best friend, an avid reader of Shoujo manga... and completely head over heels in love with Sizer.
- Cannot Talk to Women: At the beginning of the manga, he's incapable of interacting with females without keeping his piano close.
- Celibate Hero: Not that he doesn't like the ladies, it's just that he gets a nosebleed from being around them. It takes him several years after they got married to work up the guts to impregnate Sizer, and the sequel states that even then he always keeps one eye closed during sex.
- Chick Magnet: Manages to charm multiple girls over the course of the story, however, his nosebleed problem prevents him from going anywhere with them.
- Crazy Jealous Guy: When he becomes convinced that Sizer has a thing for Lute.
- Cloud Cuckoolander: He frequently hallucinates wild fantasies.
- Crouching Moron, Hidden Badass: Like Hamel, he's a foppish idiot one minute, an absolute wrecking ball the next.
- Defeat Means Friendship: Introduced as an enemy trying to avenge his parents by killing Hamel but settles down after Hamel defeats him and Flute talks him down.
- Demoted to Extra: In the video game, as a result of it stopping right at his introduction. He still has it better than most of the cast, who don't appear at all.
- Determinator: Chestra deals enough damage to kill him several times over, and yet he still keeps on fighting.
- The Ditz: Raiel's not exactly dumb, just hopelessly naive and overly trusting. He plays the patsy to basically everybody at one point or another.
- Dragged into Drag: Multiple times.
- Distracted by the Sexy: Although he has a flimsy definition of sexy. As in standing near a girl is enough.
- Dogged Nice Guy: Towards Sizer to an almost ridiculous extent.
- Elegant Classical Musician: He’s a brilliant pianist, just as talented as Hamel is with the violin. Like Hamel, he learned it from Pandora.
- Emotion Bomb: Like Hamel, he can manipulate emotions with magical music.
- Foil: To Hamel. Hamel is a Jerkass who's extremely closed off from other people and fights with a string instrument while Raiel is a Nice Guy and a Love Freak who fights with a percussion instrument. In their romantic relationships, Hamel constantly pushes Flute away while Raiel hopelessly pursues Sizer. His ability to move on from his past also contrasts Hamel getting hung up on his.

- Heterosexual Life-Partners: He was Hamel's first friend, and has remained his closest friend for most of his life.
- Hopeless Suitor: Towards Sizer.

- Love at First Sight: Falls for Sizer the moment he sees her.
- Love Freak: His goal in life is to spread love across the world and frequently trails off on romantic fantasies. He also wholeheartedly believes that love can redeem anyone, particularly Hamel and Sizer.
- Masculine Girl, Feminine Boy: With Sizer. He's obsessed with love and romance and is an avid reader of Shoujo manga while she's a stoic, battle-hardened warrior and an extremely blunt person.
- Mighty Glacier: His piano has a much greater range of effect than Hamel's violin, at the cost of mobility.
- Mind-Control Music: Unlike Hamel, Raiel can outright brainwash people with music.
- Mistaken for Gay: He and Hamel get mistaken for a couple after sharing a kiss.
- Mood-Swinger: Goes from ridiculous spazzing, to overdramatic whining and then to dramatic hero mode at the drop of a hat.

- Musical Assassin: Fights with a magical golden piano.
- Musical Theme Naming: He's named after a kind of windup organ.
- Nostalgia Filter: Looks back fondly on Pandora's constant attempts to murder him when he was a kid.
- Nice Guy: Easily the nicest guy on the whole team, making him a major contrast to Hamel. Chestra even calls him a nice guy while he beats him to death.
- He forgives Hamel for slaughtering his entire village almost immediately! He couldn't control himself, but still!
- Nose Bleed: All the damn time! Seeing a girl's knee is enough to set him off!
- Official Couple: Becomes one with Sizer shortly before the final battle.
- Plucky Comic Relief: Flute describes him as "the perfect comic relief" and while he's perfectly capable of serious moments, his misfortune, foppishness and nosebleeds tend to make him a frequent source of humor.
- Pretty Boy: Hamel even claims he's prettier than Flute!
- Put on a Bus: He gets heavily injured and hospitalized for most of the Vocal arc.
- Red Oni, Blue Oni: The blue to Hamel's red and the red to Sizer's blue.

- Roaring Rampage of Revenge: Introduced out to avenge his parents death by killing Hamel, but calms down after a fight.
- Sensitive Guy and Manly Man: Sensitive guy to Hamel's manly man.
- Shipper on Deck: States that Flute would be a good match for Hamel. He even tries to set them up for a date at some point.
- Single-Target Sexuality: Played with. After Sizer joins the team, his nosebleeds are triggered by her alone and rather than by anything female like before.
- Summon Magic: His piano is used to summon familiars. His favorite is fire bird but he also has some water dragons.
- Team Mom: Always fretting about his teammates well being.
- Tragic Keepsake: His piano belonged to his parents before him.
- Undying Loyalty: Willing to put aside his anger at losing his parents to follow Hamel, which speaks volumes about his character. He's also just as devoted to Sizer.
- Vitriolic Best Buds: With Hamel. They spend a lot of time mocking each other over things they did as kids.
- Weak, but Skilled: His golden piano isn't as powerful as Hamel's violin but it has a wider area of attack and can target multiple enemies at once. This becomes more noticeable later on, when his teammates continue to gain more and more powerful moves while he has to get by through the moves he's always had mixed with clever tactics.
- Wrong Genre Savvy: Assumes he's the love interest to Sizer in a Shoujo manga... for some reason.
The prince of the fallen kingdom of Dal Segno who joins Hamel on his quest in hopes of avenging his people. While extremely bratty and self absorbed, he has a strong sense of justice and is secretly very unsure of himself. While he lacks any magical powers, he is a Master Swordsman who wields three swords, his mother's, his father's and his own, at once and can slice through Mazoku with ease.
- Adapted Out: Removed from the story entirely in the OVA.
- Adorably Precocious Child: While he's definitely still a kid, he's a lot more mature than most people his age. Justified in that he's had to grow up fast after all he's been through.
- Anime Hair: He's got the classic spiky style.
- Badass Adorable: A cute little kid who takes out two of the Mazoku generals!
- Badass Normal: He's got no magic at all.
- BFS: Three of them.
- Big Damn Heroes: Saving Flute and Queen Horn from Guitar during the war of Sforzando.
- The Big Guy: While he's both the shortest and the youngest of the team by a wide margin, he's the only member of the party who relies on pure brute force rather than magic.
- Bratty Half-Pint: He's incredibly bratty and self-absorbed most of the time.
- Character Development: Becomes progressively more mature and heroic as the story continues, which becomes most pronounced when he forgives Sizer.
- Coming of Age Story: Has some of the most visible character growth of the entire cast.
- Cowardly Lion: For all of his bragging, he tends to cry and hide when confronted by Mazoku. Nonetheless, he always gets past his fears by the end.
- Deliberately Cute Child: He abuses his cuteness to get what he wants pretty frequently, though this starts to go away later on.
- Demoted to Extra: After Drum's defeat he drops out of the story entirely for several volumes. Once he comes back he returns to being a central character.
- Determinator: His battles tend to consist of him getting the crap beaten out of him before completely turning it around at the last minute simply by not giving up.
- Dirty Kid: Takes any opportunity he can get to cop a feel on Flute.
- Dual Wielding: Wielding three swords years before Zoro.
- Fallen Princess: Rare male example, and he's determined to return his kingdom to its former glory.
- Glass Cannon: He's plenty strong, but as a kid he can't take much of a hit.
- The Good King: By the epilogue he's become this to the rebuilt Dal Segno.
- Heroes Prefer Swords: The only main character for the longest time to wield a conventional weapon.
- He's All Grown Up: During the epilogue he's shown to have become a very nice looking Bishōnen.
- Inferiority Superiority Complex: Despite his cockiness, he views himself as incredibly weak and a burden on the rest of the team. It generally takes a good pep talk from Flute to get him back into action.
- Jerkass: A match in jerkassery even for Hamel.
- Jerk with a Heart of Gold: The jerk part even starts to disappear entirely later on.
- Kidanova: Proposes to Flute moments after meeting her and is extremely happy to help Hamel peek in the hot springs.
- Kid Hero: He's eight.
- Leitmotif: Finlandia.
- Likes Older Women: Interested in both Flute and Sizer, who are seven and nine years older than him, respectively. Even his wife Cornet is five years older than him.
- Mama's Boy: Justified in that he's still just a kid.
- Miles Gloriosus: Talks a big game but is quick to cower at the sign of battle. Justified in that he's only eight years old.
- Mouthy Kid: He's quick to talk back to Hamel, whose just as likely to mouth off to him.
- Musical Theme Naming: Put his first and last names together.
- Official Couple: With Cornet of all people at the end of the story. Even he's confused by it.
- Overshadowed by Awesome: Worried of becoming this next to his teammates. While he's definitely the weakest member of the team, he defeats both Drum and Guitar, and thus he's definitely not this.
- Put on a Bus: After the war of Sforzando the team splits up and Trom isn't seen again for quite a while. It gets to a point where he starts complaining about his lack of screen time during the plot summaries at the beginning of each volume.
- The Bus Came Back: Comes back just in time to help Hamel and the others defeat Orgel.
- Signature Move: Scissor Slash.
- Spoiled Brat: Got everything he wanted when he was little and still expects just as much despite his kingdom being destroyed.

- He takes another during his final battle with Guitar.
- Tragic Keepsake: He wields both of his parents' swords in battle.
- Warrior Prince: Tries to be one, and grows into one by the end.
Hamel's longest traveling companion. A small black raven who is extremely knowledgeable about the world. He is actually the former Hawk King of Chestra's army and one of the most powerful Mazoku in existence until he was rescued from near death by Hamel's mother Pandora and gave up his evil ways to protect her. He made a promise to Pandora to raise Hamel to become a good person and and serves as his mentor and advisor throughout the story.
- All-Powerful Bystander: Justified. His magic power is almost completely gone, so if he were to enter his super powerful true form, which could effortlessly defeat almost all of the Mazoku, he would most likely die soon afterwards.
- Anti-Villain: When we finally see the flashback of when he turned good he's grown tired of all the needless slaughter the Mazoku cause.
- The Atoner: The story begins at a point where he's been atoning for several years so we don't find out until we learn his backstory.
- Badass Longcoat: His humanoid form sports a fantastic one.
- Big Damn Heroes: Saves Hamel from Chestra during the final battle.
- Cast from Lifespan: Like all Mazoku, he has a limited reserve of magical power that he can use before dying. Oboe used nearly all of his defending Pandora from the Mazoku army to a point where he has to conserve his power by remaining in his crow form or else he'll die. He narrowly manages to survive turning into his normal form thanks to Flute's magic.
- Chekhov's Gunman: He's initially simply Mr. Exposition and Hamel's traveling companion, we learn his backstory.
- The Comically Serious: Tries to remain serious despite the ridiculous of the world around him.
- Clever Crows: He's a crow as well as the resident Mr. Exposition.
- Cool Old Guy: Hundreds of years old at the earliest but also incredibly badass.
- Curbstomp Battle: Oboe vs. the entire Mazoku army. Though it does drain him of nearly all of his power in the process.
- Deadpan Snarker: And considering the stuff that happens around him, he has plenty of opportunities to put his skills to use.
- Dirty Old Man: He isn't one, but After seeing his humanoid form, Flute thinks back to several of the things he did that, while cute and perfectly fine in bird form, come off as incredibly creepy when you realize a gigantic old man was doing it, most notably sitting on her head.
- 11th-Hour Ranger: Finally enters his true form to protect Hamel during the final battle, the first time in the main story that he ever engages in combat.
- Four-Star Badass: The former second ranked Mazoku general surpassing perhaps even Bass in power.
- Gentle Giant: His human form towers over the rest of the cast, but he's an incredibly kind person.
- Heel–Face Turn: He performed his before the story began.
- Heroic Sacrifice: Twice, though he survives both times. He first exhausted all of his magical power defending Pandora, Hamel and Sizer from the Mazoku armies but was narrowly saved from death by Pandora feeding him her blood, and he later uses up even that fending off Chestra, but gets healed by Flute's magic.
- Idiot Crows: Often explodes at Hamel in a barrage of "You idiot!"
- Involuntary Shapeshifter/ Voluntary Shapeshifter: Manages to be both at once. While he can willingly shift between his humanoid and crow form, his magic power is nearly completely exhausted and thus returning to his humanoid form would kill him in about an hour.
- Lightning Bruiser: Powerful enough to curbstomp almost all of the Mazoku army at once. He even gives Bass an Oh, Crap! moment.
- Like a Son to Me: While he frequently snaps at him, Oboe loves Hamel like a son. Likewise, Hamel respects Oboe more than any other character and abuses him significantly less than he does the rest of the team.
- Love Martyr: To Pandora and Hamel. Watches over Hamel no matter how ungrateful the task is (when your adoptive son would rather cook you than go hungry for a day, one must be a perfect saint).
- Mr. Exposition: His main role is to provide exposition on the Mazoku and the origins of the music during battle.
- Musical Theme Naming: After an Oboe.
- Noble Demon: A flashback to his days as a general shows even as a villain he was still infinitely more noble than any other Mazoku.
- One-Man Army: He managed to take out the entire Mazoku army besides Bass and Chestra while defending Pandora and her children. Bass even doubts that he'd be able to defeat him in battle.
- Only Sane Man: Even more so than Flute. He has the fewest lapses into insanity out of the entire team. That doesn't mean he still doesn't have them.
- Parental Substitute: Raised Hamel for most of his life. Hamel outright states that he considers Oboe to be his real father, and Oboe thinks about him as "my son" more than once.
- Power Limiter: His crow form uses significantly less power than his normal form, which he needs to do since using any more of his power will kill him.
- Rescue Romance: Pandora rescued him from near death when they first met and he's implied to have romantic feelings for her.
- Sleep-Mode Size: His crow form is essentially this as it uses infinitely less power than his normal form does.
- The Smart Guy: The most knowledgeable of the team about both the world and the Mazoku. Justified in that he used to be a Mazoku general and is significantly older than the rest of the team.
- The Starscream: Previously the top Mazoku general until he betrayed Chestra out of his love for Pandora.
- The Stoic: While even he has his moments of blowing up over Hamel's behavior, he remains almost impossibly calm and serious during most situations.
- Story-Breaker Power: He's powerful enough to trivialize nearly everything the team faces with the exceptions of Chestra and possibly Bass and Vocal. However, when he's finally allowed to fight it's at a point where the enemy is stronger than him.
- Team Dad: It helps that he essentially is Hamel's dad and is the actual biological father of Ocarina.
- Token Adult: The only one of the Great Hopes that isn't a kid/teenager.
- Token Heroic Orc: He appears to be the only inherently good Mazoku. He raised Ocarina to be a good person and Hamel and Sizer are only partially Mazoku.
- Undying Loyalty: To both Pandora and Hamel.
- Willfully Weak: Both played straight and averted at once. While he willingly remains in a weakened state, it's only because leaving it will almost definitely kill him.
- Winged Humanoid: Has black feathery wings in his true form.
- The Worf Effect: Consciously utilizes this when he holds off Chestra. He knows he doesn't have a chance at beating him but he exhausts every ounce of his power to hold him off to give Hamel time to recover.
- Worf Barrage: It still barely fazes Chestra.
The current Hawk King of the Mazoku forces. Introduced as a cold, ruthless warrior with an unyielding lust for battle with an eerie resemblance to Hamel, her uncontrollable nature makes her a problem for both the heroes and the Mazoku. We eventually learn that she's Hamel's long lost sister, who was kidnapped by the Mazoku as a baby and raised into a ruthless killing machine. Despite this, she still has good inside of her, and eventually defects from the Mazoku and joins the heroes. She tends to be a blunt talker, but is really a good person inside who desperately wants to make up for her long life of bloodshed.
- Adaptational Villainy: She's a complete psychopath in the anime, with no hints of any sort of Heel–Face Turn.
- An Arm and a Leg: Loses them after exhausting her magical power. Ocarina sacrifices her remaining power to give Sizer new limbs before she dies.
- Angelic Beauty: Frequently described as being beautiful and resembles the traditional image of an angel.
- Anti-Villain: She gets some time devoted to painting her in a more sympathetic light while she's still a villain.
- The Atoner: Her character arc revolves around trying to make up for her bloody past and coming to terms with it.
- Badass in Distress: When Guitar captures her and when Bass rips her soul out.
- Berserk Button: Guitar suspected her true loyalties, and mocks her for killing so many humans in a vain attempt to deceive the demons, seal them away with the Box and save her mother, concluding by calling her a traitor. Cue a mostly one-sided battle stopped only by his underhanded planning. Orgel later uses the same tack, with the same results.
- Beta Couple: With Raiel, though it’s mostly one sided on his part. until the final battle.
- Blood Knight: Absolutely ruthless in battle. She’s an angel but has a reputation for being worse than the Mazoku.
- Broken Ace: Beautiful and both incredibly powerful and talented, but plagued with personal problems.
- Broken Bird: Deep down she’s a very sad, lonely girl who believes she was thrown away by her own mother. Battle was the only outlet for her pain and for a long time she considers herself to be irredeemable.
- Brother–Sister Team: Becomes this with Hamel, though it takes some time to happen.
- Brutal Honesty: Very blunt and often downright tactless.
- Cain and Abel: Starts as the Cain to Hamel’s Abel. They reconcile after Sizer joins the good guys, though it takes a while.
- Came Back Wrong: After having her soul ripped out, Vocal replaces it with a dark orb, turning her into a mindless killing machine.
- Clingy Jealous Girl: After finally hooking up with Raiel, she doesn’t take Fife’s hitting on him very well.
- The Comically Serious: While she's too oblivious to be the Only Sane Man, her serious nature and lack of a sense of humor makes her this during the lighter moments.
- Cool Helmet: A red Mazoku skull.
- Dark Magical Girl: Starts a counterpart to her heroic brother, a better fighter than any of the good guys, broken inside and ends up undergoing a Heel–Face Turn.
- Death Seeker: Slips in and out of it.
- Defrosting Ice Queen: Starts off cold and stand-offish, but after spending some time with the gang she opens up to reveal her true, kind nature.
- Easily Forgiven: Played with, while the majority of the party forgives her immediately, just about every other character doesn't, most notably herself.
- This is completely averted by Trom, who it takes an entire story arc to forgive Sizer.
- 11th-Hour Superpower: After Chestra kills Pandora in front of her, Sizer loses it and transforms into a Mazoku - growing horns and turning her wings black. This is form is said to be on par with Hamel’s Mazoku form.
- Evil Costume Switch: Thanks to Vocal.
- Evil Counterpart: Initially one to Hamel. He's a demonic Anti-Hero and she's an angelic Anti-Villain.
- Fallen Angel: She’s stated to be half human, half angel, but starts off working for the Mazoku.
- Female Angel, Male Demon: Despite having both angel and Mazoku blood, her angel qualities are brought up much more frequently, and she has little to no Mazoku apparent attributes. This is explained by her angel blood being dominant over her Mazoku blood. She briefly enters a Mazoku form similar to Hamel's during he final battle with Chestra, however.
- Final Boss: Of the video game, despite not meeting Hamel until a while after that point in the story. Most likely done to include her in the game due to her popularity.
- Good Wings, Evil Wings: Her wings used to be red, soaked with the blood of her victims. They turn white after her Heel–Face Turn. Dark Sizer has black wings.
- Green-Eyed Monster: At first she hates Hamel because he got to be with their mother while she suffered in the Mazoku world.
- Half-Human Hybrid: Half human, half angel. Weirdly enough, since she’s the daughter of a human and a Mazoku. Like Hamel, she’s actually half Mazoku, quarter human and quarter angel. The angel part is just more dominant.
- Half-Identical Twins: She and Hamel strongly resemble each other.
- Heel–Face Turn: Joins the heroes about a quarter of the way into the story.
- High-Heel–Face Turn: The sole woman on the Mazoku's side defects to the hero's team.
- Heterosexual Life-Partners: With Ocarina, strangely mixed with Parental Substitute.
- I Just Want to Be Loved: Desperate for her mother’s love.
- I Just Want to Have Friends: “This is fun… having friends is what I always wanted.”
- Implausible Fencing Powers: Her absurdly large and long Sinister Scythe, and what she can do with it, is staggering.
- Innocent Fanservice Girl: Having been raised by Mazoku, she hardly has any knowledge of the human world. Hamel takes advantage of it by talking her into wearing various sexy costumes.
- Instrumental Weapon: Her scythe has a flute embedded in the handle.
- Leitmotif: Ride of the Valkyries.
- Lightning Bruiser: Unmatched for in speed and has superhuman strength.
- Light Is Not Good: Initially one of the main antagonists despite being angelic in appearance. Averted once she joins the party.
- Living Weapon: Her armor is a transformed Valkyrie.
- Magical Flutist
- Masculine Girl, Feminine Boy: With Raiel. She’s a tough, no-nonsense warrior and he’s a ditzy love freak.
- More than Mind Control: Essentially brainwashed from early childhood to be convinced that her mother hated her to make her the perfect ruthless soldier.
- Ms. Fanservice: Shown in Stripperiffic costumes rather frequently, and becomes naked whenever she plays her flute. This gets lampshaded repeatedly when Hamel forces her into wearing them.
- Musical Theme Naming: Synthesizer.
- No Social Skills: Being raised by Mazoku doesn't do much for you socially, and as such she has trouble picking up on social cues, particularly Raiel's.
- "Not So Different" Remark: After seeing Hamel struggling with his Mazoku blood, she realizes he’s suffering just as much as her. It alleviates some of her hate but it still takes her time to start caring for him as a brother.
- Oblivious to Love: She has no idea Raiel has feelings for her, and his Shoujo-inspired attempts to woo her confuse her to no end.
- Official Couple: With Raiel just before the final battle.
- One-Woman Army: Destroyed countries singlehandedly - even the military superpower Slur. She was able to take on the entire Beast Army to the point where Guitar had to threaten Pandora to stop her from slaughtering his soldiers.
- People Puppets: Briefly serves as one to Vocal in her Dark Sizer form.
- Red Baron: Known as the “Red Witch of Hameln” and “Queen of the Sky”. She hates the former but proudly owns the latter.
- Redemption Demotion: While still an incredibly effective team member, she loses her country-devastating power when she joins the group.
- Red Oni, Blue Oni: The blue to both Hamel and Raiel.
- The Rival: To Hamel before her Heel–Face Turn.
- She was also this to Drum back when he was still alive.
- Polar Opposite Twins: With Hamel.
- Sensible Heroes, Skimpy Villains: While her normal outfit is pretty modest, Dark Sizer's outfit doesn't leave much to the imagination.
- Sexy Villains, Chaste Heroes: Minus the implicit skimpiness, this is usually highlighted by the contrast between her and Raiel. Sizer's normal outfit is very modest; "Dark Sizer" is legitimately Stripperific.
- Shoulders of Doom: Her shoulder armor pieces are huge. Even more so when she turns evil - Dark Sizer’s shoulder pads are longer than her torso.
- Sinister Scythe: Her weapon of choice.
- The Sixth Ranger: Joins the team later than the rest of the group, was previously a villain and starts off considerably stronger than everyone else. She's a perfect example.
- Stripperiffic: Dark Sizer's outfit consists of a black leather bikini top and thong and nothing else.
- Sugar-and-Ice Personality: Generally cold and aloof, though this has more to do with her cruel upbringing than her being a mean person.
- Summon Magic: Playing “Ride of the Valkyries” on her scythe-flute summons Valkyrie spirits.
- Superpowered Evil Side: Her Mazoku form.
- Tomboy and Girly Girl: The tomboy to both Flute and Ocarina's girly girl.
- Tyke Bomb: Kidnapped by Mazoku as a baby. They told her Pandora abandoned her and raised her to hate humans and become a ruthless killing machine.
- The Unfavorite: Believes Hamel to be the favorite child, while in reality Pandora loved them both equally. Chestra, however, is much more focused on Hamel ascending to his throne and pays almost no attention to Sizer.
- Unwitting Pawn: To Bass and Guitar. They knew she was planning to reseal them in Pandora’s Box, and they made sure she’d fail so they can have the Box.
- "Well Done, Daughter!" Girl: A lot of her issues stem from the fact she believed Pandora abandoned her. Even after she learns the truth, she’s still worried Pandora might not love her.
- Wild Card: When working for the Mazoku, she often picks fights with Drum and ignores orders, doing as she pleases. She actually plans to betray the Mazoku and reseal them in Pandora’s Box.
- Winged Humanoid
- The Worf Effect: Vocal tears her apart in their first fight. She does better the second time, but she still ends up losing.
Oboe's daughter and Sizer's lifelong companion. She was left in charge of taking care of Sizer as a baby by Bass and serves as both a parental figure and best friend to Sizer. While she was raised by Oboe into a surprisingly kindhearted young woman for a Mazoku, her fear of Bass' wrath forced her to allow Sizer to become a villain. When Sizer defects, Ocarina happily tags along.
She is later critically injured by Dark Sizer and sacrifices her remaining power restoring Sizer's body after she regained her soul, making her the first major character to die in the series.
- Anti-Villain: She’s one of the only two good Mazoku, but let them use Sizer because Bass threatened to kill Sizer if she learned the truth.
- Chuck Cunningham Syndrome: Nowhere to be seen in the OVA, despite Sizer being on the team.

- Good Scars, Evil Scars: The one across her eye is a neat, Good scar.
- Heroic Sacrifice: To save Sizer.
- Heterosexual Life-Partners: With Sizer. An odd mix with Parental Substitute as though she's Sizer's surrogate mother, the two of them physically appear to be the same age and act more like best friends than mother and daughter.
- High-Heel–Face Turn: In the same vein as Sizer.
- Informed Ability: Her status as former Hawk King suggests that she's a top tier Mazoku, however she only occasionaly participates in fights and when she does she gets knocked around.
- It's All My Fault: Blames herself for Sizer’s suffering, because she didn’t tell her the truth.
- Killed Off for Real: The first major character to die.
- Love Martyr: Gives her life to turn Sizer back to normal.
- Like Parent, Like Child: Former Hawk Kings who changed after meeting humans and learned the meaning of love. Each of them serves as a parent figure for one of Pandora’s children, and would gladly sacrifice themselves for them.
- Ms. Fanservice: Just look at her outfit. When Hamel sees her human form for the first time, he’s excited to finally have a scantily clad lady in the manga.
- Morphic Resonance: Her human form’s hair is the color of her crow form’s feathers.
- Musical Theme Naming: She’s a bird Mazoku and ocarinas are often shaped like birds.
- Nice Girl: She's incredibly cheery and surprisingly personable, in stark contrast to Sizer.
- Older Than They Look: Her humanoid form looks no older than the rest of the team and she acts about the same age, but looked exactly the same when Sizer was a baby and as a Mazoku is most likely considerably older.
- Parental Substitute: Raised Sizer ever since she was small.
- The Power of Trust: How she and Raiel change Dark Sizer back. It costs Ocarina her life.
- Put on a Bus: Leaves before the gang reaches Score and comes back for the Vocal arc.
- Sacrificial Lion: The first major character to die.
- Satellite Character: More or less defined completely by her interactions with Sizer and, to a lesser extent, Oboe. Later on she begins to show signs of a budding friendship with Raiel, but she's killed off before anything comes of it.
- Tomboy and Girly Girl: Girly girl to Sizer's tomboy as she is considerably more feminine and personable.
- Voluntary Shapeshifter: Is in her crow from at first, but sticks to her human form after she and Sizer join the good guys.
- Winged Humanoid: Causing her to look like an angel.
- The Worf Effect: As the Hawk King before Sizer, she has to be one of the most powerful Mazoku. Unfortunately, she only gets to fight against even stronger opponents, like Guitar and Vocal.
- Yaoi Fangirl: She's visibly pleased when Hamel and Raiel kiss.
- The valkyries gave her yaoi manga to read. Oboe is quite shocked, saying he did not raise her like this.
Raiel's favorite summon. A massive bird made out of fire capable of immensely powerful fire-based attacks that can defeat swarms of Mazoku in seconds. Outside of battle, it is actually adorably docile and desires only to make Raiel proud. However, Raiel's constant screw ups in battle cause him to frequently take his anger out on Fire Bird.
- Butt-Monkey: Raiel often takes his frustrations on it and ropes it into helping him woo Sizer.
- Forgot About His Powers: Sometimes he forgets he can set people on fire by standing too close.
- Leitmotif Stravinsky’s Firebird.
- Noble Bird of Prey: Its combat form is a gigantic, terrifying phoenix made of fire.
- Playing with Fire: Naturally all of his attacks are fire based.
- Ridiculously Cute Critter: When it doesn’t fight, it is adorable.
- Super-Deformed: When outside of battle, it goes from a massive, highly-detailed beast to an adorably simplistic bird.
- The Voiceless: Never utters a word, being a bird and all.
- "Well Done, Son" Guy: Wants Raiel to praise it and runs away crying when it doesn’t feel appreciated.
Sizer's own group of summons. A pack of nine exceptionally powerful Valkyries capable of powerful combination attacks and transforming into Sizer's armor. Outside of battle, they surprisingly act like a group of typical teenage girls, frequently flirting with Hamel and Raiel and gossiping about other character's love lives. Their names are Schwertleite, Waltraude, Helmwidge, Gerhilde, Rossweisse, Gringerde, Seigrune, Ortlinde and Brunhilde, though they differ little in personality.
- Amazon Brigade
- Crouching Moron, Hidden Badass: Inverted. They're introduced in the heat of battle as antagonists, where they prove to absolutely dominate their opponents with incredible efficiency, but are revealed to act like giggling school girls when finally shown outside of battle.
- The Dividual: They don't really have distinct personalities and more or less function as a single character.
- Empathic Weapon: Their mood depends on Sizer’s.
- Genki Girl: All of them are exceedingly peppy when outside of battle.
- Gossipy Hens: Out of the battlefield.
- Gratuitous German: All of their names, which you only get to hear once to make it especially confusing.
- Heroic Sacrifice: Brunhilde sacrifices herself so Sizer can kill Vocal. Sadly, it doesn’t work.
- Immortality: As spirits, they can only be killed by someone with holy powers. Like Brunhilde.
- Leitmotif: Ride of the Valkyries, shared with Sizer.
- Let's Get Dangerous!: They act like flirty teenage girls outside of battle, but when the fighting starts they become unstoppable forces of nature with deadly focus.
- Living Weapon: Can transform into Sizer’s armor.
- Meaningful Name: Brunhilde means armored battle maiden. The character Brunhilde is a battle maiden who literally turns into armor
- Perky Female Minion: They were this to the Mazoku when Sizer was still with them.
- Shipper on Deck: Actively help Raiel’s attempts to woo Sizer. They also seem to be very excited about Hamel and Raiel’s kiss…
- Undying Loyalty: To Sizer.
- The Worf Effect: They only ever win when they're working for the Mazoku.
- Yaoi Fangirl: They all go crazy when Hamel and Raiel kiss.
The Queen of Sforzando, the most powerful human kingdom. A kind, wise ruler who cares for her people like a mother, and is revered by all for her powerful healing magic. She’s also Flute’s mother. While her queenly duties stop her from actively participating, she communicates with the heros via crystal ball, guiding and supporting them on their journey.
She finally exhausts the last of her power assisting Flute in summoning the Goddess that provides humanity the final push it needed to penetrate the Mazoku's defenses.
- Action Mom: Leads her troops to battle.
- Adaptational Villainy: She's a stone cold Jerkass in the anime, to the point of almost serving as a secondary antagonist to the Mazoku.
- Amazingly Embarrassing Parent: Whenever she calls the team on her crystal ball it's generally to humiliate Flute rather than give advice. At least she means well.
- Back from the Dead: Briefly returns to life to take Lute to heaven and to help console Flute.
- Barrier Warrior: Can create powerful deflector shields.
- Big Good: The Leader of one of the most influential nations in the world and the one who assists the main party most frequently.
- Cast From Hitpoints: Using healing magic depelets her lifespan.
- Cloudcuckoolander: While she's both an intelligent and wise queen, she can be extremely weird. Some examples include holding a holiday in tribute to her daughter that centers around dressing a bull like her and slaughtering it and forgetting her husband's existence.
- Cross Attack: She shoots laser beams from a Magic Staff that has crosses embedded on it.
- Deus ex machina: After Flute was impaled by Mazoku Hamel, Horn teleported to the scene and healed her, saving her life.
- Doting Parent: Played for Laughs. She wants to celebrate and honor Flute, but the execution leaves something to be desired - for example, she made up a festival where they celebrate Flute’s suffering, name a cow after her and then eat the Flute cow.
- Dying Moment of Awesome: Summons an almighty goddess to help the heroes in her final moments.
- Good Parents: Extremely kind and supportive to both of her children, though circumstances push her away from them.
- Good Reason For Parental Abandonment: Sent Flute away because Sforzando was at war and it wasn’t safe for her.
- Healing Magic
- Heroic Sacrifice: Lends the last of her power to help Lute summon the goddess and dies shortly afterward.
- The High Queen: She is the matriarch of the entire Sforzando and is powerful enough to validate her authority, but she plays with this image by being an extremely awkward Doting Parent to Flute.
- Incurable Cough of Death: As a result of using her power too much.
- Lady and Knight: Bright Lady to Clari's White Knight.
- Mama Bear: Not only to her children, but to all the people of Sforzando.
- Missing Mom: Initially Flute's, who is both quite shocked and angry when she learns who she is.
- Mum Looks Like a Sister: She looks only slightly older than her son, who looks twenty at the oldest.
- Mission Control: Serves as this to the main party alongside Clari for most of the adventure through her crystal ball, though she tends to embarass Flute rather than provide any useful information.
- Musical Theme Naming: French horn.
- My Greatest Failure: Not being there for Flute when she grew up.
- Not So Above It All: Very enthusiastic about Hamel’s suggestion to kill Olin… though to be honest, he completely deserved it.
- Older Than They Look: Considering the timeline, she should be in her sixties, but appears half of it. Justified since she had holy blood. She starts looking her age at the end of the manga, when she’s close to death.
- Open-Minded Parent: Gave Flute her blessing when she wanted to keep traveling with Hamel.
- The Pollyanna: Almost obnoxiously optimistic and cheerful, even in the least appropriate situations.
- Stepford Smiler: This is heavily suggested to be done to keep her subjects from worrying about her failing health.
- Reasonable Authority Figure: Guides the heroes on their journey and speaks in Hamel’s favor in front of the other rulers, who are reluctant to trust humanity’s fate to a half-Mazoku.
- Royalty Super Power: The healing power is passed from mother to daughter in the Sforzando royal bloodline.
- Royals Who Actually Do Something: Goes out to battle and is essentially the political leader of humanity.
- Sacrificial Lion: Gives her life to help Flute summon the goddess.
- Secretly Dying: A bit of an Open Secret, but she's actually in a far worse condition than she appears to be.
- Squishy Wizard: An incredibly powerful magic user bogged down by her weak constitution and poor health.
- This Is Something She's Got to Do Herself: Didn’t counsel Flute when she doubted Hamel, because trust is something she had to learn herself.
- Tough Leader Façade: An odd example. While she's maybe a little too overly emotional most of the time, she hides her failing health behind a cheery guise.
- Universally Beloved Leader: She's a kind, just ruler who cares deeply for her people, and they love her back.
- Vague Age: Looks to be in her late twenties, but is at least in her fifties, and may actually be older. We're never told just how old she is.
The High Priest of Sforzando, commander of the Magic Corps and one of the most powerful mages in the world. While usually cool, serious and collected, he has his silly moments. He’s absolutely loyal to Queen Horn and his greatest desire is to protect Sforzando. Prince Lute inspired him to become a mage when he was a kid and Clari still adores him (and possibly more) to this day.
- The Ace: One of the most powerful mages in the world, second only to the Sforzando royals.
- Ambiguously Gay: Despite getting offended whenever he gets called a homo, he admits that he loved Lute. However, whether this kind of love was platonic or romantic is deliberately kept ambiguous.
- An Arm and a Leg: Loses all four limbs in a fight against Bass. Gains robotic prosthesis in the epilouge.
- Artificial Limbs: By the end of the series, all of them.
- Berserk Button: Implying that he’s gay or making his little sister Cornet cry.
- Big Brother Instinct: Loves Cornet dearly, spoils her rotten and threatens to fry anyone who makes her cry.
- Chick Magnet: Has scores of ladies interested in him, though he shows no interest in any of them.
- Defrosting Ice King: Starts out cold and antagonistic towards the main party but is a close and trusted ally by the end.
- Detect Evil: Could tell that Oboe was a Mazoku from a glance. Also spotted Mazoku disguised as humans and stopped them from assassinating Horn.
- Determinator: Fights to restore Lute’s back even after losing his limbs.
- Family Theme Naming: Both Net siblings have names starting with C.
- Flash Step: Can cross great distances in an instant, though constant use exhaust him greatly.
- Forgot About His Powers: Could have helped in the battle of Slur if he didn’t forget he can move from place to place in an instant.
- Generation Xerox: Intentionally modeled himself after Lute, his hero and mentor.
- Guest-Star Party Member: Accompanies Hamel to rescue Sizer, but immediately leaves the group after that and never returns.
- Knight Templar Big Brother: Played for Laughs.
- Lady and Knight: White knight to Queen Horn's bright lady.
- Long-Haired Pretty Boy: A major reason for why Hamel thinks he's gay.
- Magic Knight: One of the strongest mages in the world and also skilled in melee combat.
- Mission Control: Serves as one to the heroes for most of the story through Horn's crystal ball, and, unlike Horn, he actually tends to give useful information to them.
- Mistaken for Gay: Much to his dismay, the first thing Hamel says when he sees him is accusing him of being "a homo". Although there is some implication that he might actually be gay, though there's not enough evidence to prove it.
- Musical Theme Naming: Clarinet.
- My Sister Is Off-Limits: Does not want Hamel anywhere near Cornet.
- One-Man Army: Takes down entire battalions of Mazoku, on multiple occasions.
- Only a Flesh Wound: Keeps going even after being thoroughly mauled by Drum. He loses all four limbs and somehow, he still survives.
- Only Sane Man: Immediately acknowledges the insanity of the Five Hopes and frequently plays straight man to Queen Horn, but he can spaz out just like the rest of them. Justified since Hamel really knows how to push his buttons. He also tends to become absurdly goofy when adoring Cornet.
- Pretty Boy: His good looks attract him a lot of female attention and causes Hamel to think he's gay.
- Sexy Priest: The Female crusaders are all over him.
- Ship Tease: Gets some with all three of the major members of the Sforzando royal family.
- Single-Target Sexuality: Appears to be exclusively attracted to members of the royal family, receiving Ship Tease with Queen Horn, Lute, and very late into the story Flute. He is at the very least attracted to one of them, as Percuss states he can never be with his true love, which Clari agrees with. This doesn't terribly help narrow down which of them it is, as he can't be with any of them by the story's end. The sequels strongly hint that it is the last living member of the royal family.
- Sugar-and-Ice Personality: Mostly icy, but shows a soft side around Queen Horn, Flute, Lute and especially Cornet, to the point where he becomes a completely different person when around her.
- Supporting Leader: Leads the main army and is one of the most powerful good guys, but never joins the party and is not one of the main protagonists.
- Undying Loyalty: To Queen Horn and the entire Sforzando royal family in general.
- Volleying Insults: With Hamel.
- Crouching Moron, Hidden Badass: He's a surprisingly tough magic user, though he only gets to show it off a few times.
- Expy: Resembles Cogsworth.
- Every Man Has His Price: Gives Hamel money so he’ll leave Sforzando and Flute alone.
- Evil Chancellor: Subverted. He's built up as this initially but proves to be a decent, if rather fussy, person.
- Gag Nose: A big hooked one.
- High-Class Glass: Sports a monocle
- Jerkass: Toward Hamel, because he doesn’t think he’s an appropriate company for Flute. Considering Hamel’s character, it’s not that surprising.
- Jerk with a Heart of Gold: He cares deeply for the royal family, and is a pretty decent guy when not dealing with Hamel.
- Manipulative Bastard: Refused to help fix Hamel’s violin until Flute agreed to stay in Sforzando as princess.
- Red Herring: Initially hyped as being a villain, but proves to be a good guy pretty quickly.
- Stealth Hi/Bye: He can teleport.
- Undying Loyalty: To Horn and the royal family.
She’s turned into a Mazoku and gets killed… only to come back pure and kind. Her monster form is incredibly powerful and she wishes to use it to help the heroes, but considering her previous actions, they’re understandably suspicious.
- Adaptation Personality Change: Manga Cornet is a strictly comic relief character, a spazz whose psychotic behavior is played for laughs. In the anime, which removed the humor altogether, she is a serious, dutiful young woman.
- Affectionate Nickname: Clari calls her “Corr-rin”.
- Big Damn Heroes: Comes just in time to save Flute from Vocal and restore her soul. At the very end of the story she stops a Not Quite Dead Guitar from gaining Chestra's power.
- Big Sister Worship: Claims to see Flute as her admired big sister. It’s a lie to get close to her. Played straight after Cornet’s Heel–Face Turn. Once she’s cleansed of evil, she truly cares for Flute. Too bad Flute is too traumatized to appreciate it.
- Bitch in Sheep's Clothing: Appears to be an adorable little girl when in reality she's worse than most Mazoku.
- Body Horror: Turns into a horrendous monster with multiple acid dripping mouths.
- Butt-Monkey: After becoming a Mazoku she essentially serves as the butt of all the jokes in the scenes she's featured in.
- Clingy Jealous Girl: Her crush on Hamel.
- Cloud Cuckoo Lander: Judging by her fantasies about Hamel, she’s a very odd girl. Him kicking her around and shoving her in ridiculous costumes sounds romantic to her.
- Crosses the Line Twice: Her constant attempts to murder Flute are hilariously over the top.
- Deliberately Cute Child: Acts all happy and cutesy to hide her nasty, bloodthirsty streak.
- Demoted to Extra: After being hyped up as one of the major characters, she loses all relevance to the story after she finishes traveling with Hamel and Flute. Her Mazoku form is played entirely for laughs and, barring one Big Damn Heroes moment, only reduces her to a joke character.
- Enemy Mine: Played for Laughs. She adores Orgel, one of the cruelest, most vicious Mazoku in the world, because he managed to break up Hamel and Flute, albeit temporarily.
- Family Theme Naming: Both Net siblings have names starting with C.
- The Fake Cutie: She's more or less defined by being a devil underneath a sweet surface. Up until her resurrection, at least.
- Fangirl: Of the Five Hopes. She even has their Image CD's!
- Friend or Foe?: The heroes never recognize her in her Mazoku form. Even when she transforms right in front of them, they blame her of eating the real Cornet and proceed to attack her.
- Guest-Star Party Member: Accompanies Hamel and Flute for a while after the war of Sforzando but leaves immediately after they rescue Sizer and never comes back.
- Heel–Face Turn: Sort of. After she’s “killed” during her attack on Sforzando, the evil is cleansed of her and she turns into a genuinely sweet, well meaning girl.
- Humiliation Conga: After being one of the worst individuals in the entire series, she gets turned into a Mazoku and is not recognized by any of her allies, not even her own brother. From then on she's beaten up and murdered countless times by the rest of the cast.
- I Just Want My Beloved to Be Happy: After her Heel–Face Turn, she decides to stop chasing Hamel because he belongs with Flute.
- Jerkass: Maybe an even bigger one than Hamel! She attempts to murder Flute on a regular basis and shows no remorse whatsoever. She only redeems herself after she becomes reborn after getting killed as a Mazoku, which implies that she had no good in her to big with.
- Kaiju: At one point she turns into a giant Mazoku and starts to wreck Sforzando.
- Karmic Transformation: Her Mazoku form fits her rotten personality well. Too bad it sticks after she turns good.
- Little Miss Badass: She’s only thirteen, and one of the strongest magical warriors, excels in spell casting and can toss Mazoku left and right effortlessly.
- Magic Knight: Like her brother, both a powerful spellcaster and physical fighter. Her Mazoku form is incredibly powerful as well, but slow and clumsy.
- The Magnificent: Calls herself “Evil Fighter Cornet.”
- Murder the Hypotenuse: Constantly tries to kill Flute.
- Musical Theme Naming: Cornet.
- My Sister Is Off-Limits: Gender Flipped variant. A short comic in the special artbook shows her unleashing a hungry demon on some girls who were pining after Clari.
- No Guy Wants to Be Chased: Hamel really doesn’t like her, mostly because she’s too cutesy and clingy.
- Official Couple: With Trom of all people. Even he doesn’t know how it happened. The anime's epilogue hints at this and makes more sense than the manga as Cornet has been chasing and protecting him ever since her introduction. They also spend the most time with each other in the anime.
- The Pollyanna: After her Heel–Face Turn.
- The Rival: Sees herself as Flute’s romantic rival in the war on Hamel’s heart.
- Story-Breaker Power: Her Mazoku form is so powerful, it can curb stomp Vocal. This why Cornet is always written out in the later volumes, often in utterly ridiculous ways.
- Super Mode: Her Mazoku form, complete with a magical girl style transformation.
- Token Evil Teammate: One of the few heroes who can actually be called straight up evil. Not so much after her rebirth, but by then it's too late.
- Too Dumb to Live: Made a terrible potion for Flute… and drank it herself seconds after brewing it. It turned her into a horrendous Mazoku.
- Token Mini-Moe: Almost seems to be a parody, with her excessive attempts at being cute grating on most characters nerves and her real personality being an awful harpy.
- Training from Hell: Puts Flute through this, claiming it’s to help her to learn magic. She’s actually trying to kill her so she can have Hamel for herself.
- Wrong Genre Savvy: Thinks she’s the heroine in a magical girl series, with Hamel as her love interest and Flute as the evil rival.
- Yandere: Played for Laughs.
- Action Dad: Died defending his country from Mazoku on the front lines, not that anyone remembers.
- Back from the Dead: Very briefly comes back from the dead to console Flute, but it backfires as she has no idea who he is and assumes he's some old drunkard.
- Butt-Monkey: Nobody cares about him. Not his family, his subjects, nobody.
- Crouching Moron, Hidden Badass: He's played exclusively for humor, but is shown to be a strong magic user and quite the inspirational speech giver, it's just that his son Lute is far more powerful than he is.
- Forgettable Character: No one ever remembers who he is. Flute even calls him “the old drunkard.”
- Heroic Sacrifice: Sacrificed himself defending Sforzando from Mazoku troops, but...
- Senseless Sacrifice: They break through any way and his wife and subjects are far more interested in Lute's sacrifice than his.
- Joke Character
- Minor Major Character: He's the fricken' King of Sforzando! In most stories he'd be hugely important, but in this one he's lucky to even be noticed!
- No Name Given: He's not important enough to get a name. You can call him "Papa", though.
- No-Respect Guy: Nobody cares about him. At all.
- Overshadowed by Awesome: He's a strong magic user, but Lute is just so much cooler and more plot relevant than he is that it hardly matters.
- Rousing Speech: Gives some really heartfelt ones. Too bad no one appreciates it.
- Big Damn Heroes: Drop in during the battle against Bass to help Clari out.
- Chekhov's Gunman: Get name dropped multiple times and make frequent appearances in flashbacks, but never appear until near the end.
- Dangerous Forbidden Technique: They summon some insanely powerful demons to help fight Bass, which drains them of most of their power.
- A Death in the Limelight: When they finally appear in the present almost all of them die.
- The Ghost: We never see them in the present until very late into the story.
- Heroic Sacrifice: All of the men sacrifice themselves trying to help Clari save Lute.
- The Lancer: Sax is Clari's best friend, the second strongest magic user in Sforzando after him and the leader of the crusaders.
- Mauve Shirt: Get a decent amount of characterization and backstory, but are far from central characters. Almost all of them are dead by the end of their first real appearance.
- Men Are the Expendable Gender: All of the men die, but both of the women survive.
- True Companions: Clari's.
- Two Girls to a Team: While there are several men in the group, there are only two girls.
- Undying Loyalty: Towards both Clari and Lute, who they are willing to die for.
- Unlucky Childhood Friend: Both of the female members are clearly attracted to Clari, but he only has eyes for... someone else.
- We Are "Team Cannon Fodder": What their role ends up amounting to. They last long enough to buy Clari some time to recover, but not much else.
- We Hardly Knew Ye: Almost all of them die not long after their introduction and the few that survive have barely enough time to get any distinct personality.
- White Magician Girl: Both of the girls rely on support magic rather than fighting.
- The Worf Effect: All of the men get killed in their debut battle. To be fair, it was against Bass.
The King of all Mazoku, Hamel and Sizer’s father. He’s sealed in PandorasBox and the Mazoku are trying to set him free due to his infinite magic being the source of their power. Hamel's goal is to destroy him at all costs.
He’s released from the box in the later volumes, and after a long hard battle is ultimately defeated by the bond between Hamel and his companions and inspiring magical music.
- Abusive Parents: Aside from trying to eat infants to gain power, including his own children just soon after they were born, he spends the fight with Hamel acting like a psychological abusive parent emotionally putting down the son that's standing up to him.
- Adaptation Personality Change: Manga Chestra is a completely irredeemable monster. In the anime, he started as a simple man who truly loved Pandora and was driven insane by the Demon King's Power, and begged Pandora to seal him before he could be completely overtaken by the power.
- Archnemesis Dad: Hamel hates him more than anything else in the world and regularly says it to his face. Considering what Chestra planned to Hamel and Sizer as infants, still plans to do with them and how he emotionally abusively treated Pandora, the woman he came to love; the feeling is completely justified.
- Authority Equals Asskicking: He's the strongest Mazoku in the story, having been sealed away for the majority of the story and once he's once again freed and even when he's only partially released, he dwarfs the powers of even Bass with ease.
- Bad Boss: Kills a bunch of high ranking Mazoku because he feels like drinking blood. The Mazoku clearly only follow him due to him being the source of all of their power, literally following him out of necessity for survival.
- Becoming the Mask: A twisted example. He actually did grow to love Pandora during their time together, but instead of becoming even the tiniest bit more sympathetic he used his newfound understanding of love to manipulate her into unsealing his power.
- Big Bad: King of all Mazoku and the guy the Five Hopes need to bring down to save the world.
- Bishōnen Line: The lord of all evil looks like a Bishōnen with long horns, sharp fangs, and long nails. He's also capable of adopting a completely human guise while his true power was sealed away, something that his subordinates aren't capable of, demonstrating his natural superiority over them.
- Bitch in Sheep's Clothing: Acted like a kind, caring bard during his time with Pandora. Even after she learned his identity he still played himself like an Anti-Villain to get her to unseal his power.
- Black Eyes of Crazy: Showed them briefly during his fight with Hamel.
- Break Them by Talking: Provokes Hamel so he can suck more of his magical power, since Hamel’s demon blood awakens when he’s upset.
- But for Me, It Was Tuesday: When Hamel asks him how many humans he just killed, Chestra replies with “I don’t know, how many times have you eaten bread?”
- Devil in Disguise: Pretended to be human to trick Pandora into falling in love with him.
- Divinely Appearing Demons: Has the appearance of a horned, angelic looking Bishōnen wearing golden armor, but is the depraved leader of the Mazoku.
- The Dreaded: Just his projection makes people paralyzed with fear.
- Eats Babies: Plan to eat Hamel and Sizer- '''his own children''' soon after they were born.
- Eldritch Abomination: While seemingly a Bishōnen with horns, he is seemingly capable of spawning an endless number of tentacles from his body, and his presence alone is enough to distort the earth's atmosphere.
- Even Evil Has Loved Ones: Manages to somehow zig-zag this trope. He admits to Hamel that the time he spent with Pandora caused him to develop feelings of love for both her and their children, but he's so disgustingly evil that he completely disregards these emotions and instead utilizes them to manipulate the rest of his family into assisting him in unsealing his power. What a dick.
- Evil Cannot Comprehend Good: Subverted and zigzagged disturbingly. He admits to coming to love Pandora and his children, but rather than redeem him- he uses those feelings to emotionally manipulate them into doing his actions and seeing love as a tool to manipulate.
- Eviler than Thou: While the rest of the Mazoku see love as an incomprehensible thing to dislike for no discernible reason, Chestra proves to be even viler than his subordinates by using that love to manipulate his loved ones, in spite of having that same love for them and doing it anyway.
- Evil Overlord: A typical tyrannical dictator at first glance, but once his full backstory with Pandora is revealed, he comes across as even viler for being an emotionally abusive, manipulate spouse that is fully capable of eating his own children.
- Final Boss: The final enemy needed to be defeated to liberate humanity.
- Glorified Sperm Donor: He may have given birth to both Sizer and Hamel, but being the biological parent was the only thing he was good for them to the point that Hamel considers Oboe to be his proper father figure over Chestra. Considering what Chestra intended to do just after they were born and how he would later treat them, it's very justified.
- Half the Man He Used to Be: After his escape from the Box, a part of his body is missing. He even makes that joke himself at some point. By the end of the story, he's fully recovered.
- Humanoid Abomination: Looks like a handsome human with horns and claws, but his presence alone is able to shake the world asunder and he is able to manipulate his body in very unnatural ways.
- Greater-Scope Villain: He's locked inside of a box for most of the story and has little impact on the plot before his release.
- Hate Sink: A horrific king who devours his own legions to fuel his powers emotionally manipulates his lover even when he loved her, and tried to eat his newborn children. There is no redeeming qualities about him.
- He Who Must Not Be Seen: Not physically seen until late into the manga.
- Holy Burns Evil: Flute’s magic can ward him off.
- Hope Crusher: He loves to cause all kinds of pain and suffering, but seem to revel in despair especially, even drawing power from it. One of his favorite tactics is to give a Hope Spot only to yank it back in the last second, and he's done so to various characters, on multiple occasions.
- Human Resources: The “Holy Grail”, where Chestra raises his magical power by drinking human blood or absorbing human souls.
- I'm a Humanitarian: Has no problem drinking the blood of other Mazoku. Even his own children’s.
- Immortality: Implied to be Complete Immortality as he's the only Mazoku to possess infinite magical power and thus cannot die. Sealing him away is the only way to stop him from causing more havoc due to this reason.
- Kin Slaying Is A Special Kind Of Evil: What makes his decision to eat Sizer and Hamel even more despicable, was the fact that they were his own children and had given birth to them specifically for this purpose
- Knight of Cerebus: Lacks a single comedic quirk, unlike his subordinates and is played as a very serious threat in the series- with his full revival being the Darkest Hour for the series.
- Lack of Empathy: Averted. His dialogue during his battle with Hamel shows that he did develop a sense of empathy for Pandora and his children. In possibly the biggest twist ever though, it actually makes him less sympathetic as he completely disregards theses feelings and uses them exclusively to screw with his family. The other Mazoku can't understand empathy, while Chestra can but uses it to torture others even further.
- Light Is Not Good: He's a blond Bishōnen horned humanoid wearing golden armor, but he's actually an emotionally abusive, cannibalistic and conceited monster.
- Living Battery: The primary reason why the Mazoku are so desperate to revive him. He's eventually revealed to be the source of all of the Mazoku's magic power, which, due to magic also being directly tied to a Mazoku's life force, makes him singlehandidly responsible for the species' entire existence. Without him, they're doomed to eventually go extinct.
- Lovecraftian Superpower: Energy sucking tentacles.
- Manipulative Bastard: Tricked Pandora, the Holy Maiden, into falling in love with him so she’d give birth to his children and he can eat them to regenerate. Everything Hamel and Sizer had to suffer through was orchestrated by him, because suffering made them a tastier, more nutritious energy snacks.
- Moment Killer: Tends to show up during heartwarming moments and hope spots.
- Not Quite Dead: It seems like Hamel defeated him, but then Chestra comes back for last deadly attack.
- "Not So Different" Remark: Likes to screw with Hamel's head by stating their similarities.
- Offing the Offspring: Plans to use his children as energy snacks.
- Omnicidal Maniac: He has no goals for the destruction of all life that isn't himself.
- Orcus on His Throne: After his escape from Pandora’s Box. Justified since some of his body is missing and he literally can’t move. He starts kicking the protagonists around the moment he regains both feet.
- Parental Favoritism: He’s more focused on Hamel, whose Mazoku blood is more dominant than Sizer’s and therefore is better fit to be his heir.
- Physical God: He's magnitudes more powerful than even the second strongest Mazoku, actually affecting the atmosphere with his presence alone.
- The Power of Trust: How he’s ultimately defeated.
- Really 700 Years Old: He looks like a slightly older Hamel despite being older than the entire rest of the cast.
- Sadist: Enjoys making others suffer and openly revels in the pain he causes.
- Satanic Archetype: The Demon King, a angelic looking demon wearing golden armor invoking who manipulates the feelings of others to further his goals and commanding a vast army of demons. his light palette and some of his techniques invoke the image of Lucifer.
- Sealed Evil in a Can: In Pandora’s Box.
- Shoulders of Doom: He has enormous shoulder pauldrons.
- Story-Breaker Power: The heroes exhaust themselves and yet they barely scratch him. He's more than a match for Hamel with a single leg.
- As the only Mazoku with infinite magic, he's much, much stronger than even Bass and Oboe, the two strongest Mazoku below him and is actually the source of both of their powers!
- Strong Family Resemblance: Hamel looks very close to him in looks except that Chestra has longer, curlier hair and is very tall.
- Smug Snake: He's not only completely evil, but incredibly smug about it.
- Smug Super: Unfortunately, this is backed up by the fact he's the strongest Mazoku and being in the story by leagues, a fact that he fully abuses.
- To Serve Man: Sees humans and even his own Mazoku. as nothing but food.
- The Unseen: Not physically seen until late into the manga.
- Walking Wasteland: Causes massive earthquakes just by rising from his throne.
- You Have Failed Me: Pulls this on Guitar but changes his mind in the last moment.
The second-in-command of the Mazoku forces and Lord of The Underworld, he leads his master's forces in his absence. A cold, calculating Mazoku of obscene power, he lost his original body in a battle against Lute and is now reduced to a head, however, he took over Lute's body in the process, gaining all the power that comes with it.
He is killed by Lute after regaining control of his body
- Arch-Enemy: Lute's. Lute took his body, he took his soul, and the two hate each other more than anyone else in the world.
- Authority Equals Asskicking: Chestra's number two and rivaled in power only by Oboe and Vocal.
- Back from the Dead: Comes briefly back to life to taunt Hamel as a zombie.
- Big Bad: As Chestra is absent for most of the story, Bass fulfills this role in his place. While Chestra is the ultimate evil, he is the one leading the Mazoku and the plot is kicked off by his actions.
- Bishōnen Line: One of the strongest Mazoku looks identical to a human man. Although being a disembodied head lessens this quality slightly.
- Body Surf: He threw his fight with Lute to gain possession of his body and his power along with it. He plans on doing this to Flute during his final battle.
- The Comically Serious: Rarely played for comedy, but when he is, he'll be the straight man.
- The Dragon: Chestra's top general.
- Evil Counterpart: To Oboe. Both were at one point Chestra's top general who take the form of old humanoid men and posses a certain amount of nobility in comparison to the other Mazoku, but while Oboe learned to love and admire humanity, Bass became enraged at his inability to understand it. Both are also on the cusp of losing the power, but while Oboe simply opts out of fighting altogether, Bass chooses to go from one body to the next to continue fighting.
- Eyepatch of Power: It's covering up Lute's soul.
- The Heavy: Kicks off most of the plot in his master's absence.
- Humanoid Abomination: The only Mazoku without a single inhuman characteristic.
- Karmic Death: Killed by Lute, the man he kept in a Fate Worse than Death for years.
- Lack of Empathy: While all the Mazoku have this to some extent, Bass is the only one who seems to really care about it. During his final battle against Clari he expresses complete bewilderment to why he would risk his life to save a single person. It's implied his inability to understand human emotions is the source of his hatred for them.
- Losing Your Head: Lost his body in a fight with Lute and now exists simply as a head. He still possesses all of his former power plus the addition of Lute's, making him even more powerful than before.
- Orcus on His Throne: Almost never leaves Hameln. When he does show up on the scene, stuff's about to go down. This is explained by Lute running low on magical power and Bass being cautious about using too much of it.
- Power Degeneration: He seized Lute's body when his old one was running low on power. He plans on doing the same with Flute now that Lute's running low on his own.
- The Stoic: Tends to remain calm under all circumstances.
- Not So Stoic: Breaks down during his final fight with Clari.
- Story-Breaker Power: He possesses both his own power and Lute's, making him almost unfairly strong.
- Undying Loyalty: Unlike the other Mazoku, who follow Chestra out of necessity, Bass seems to genuinely respect him.
- Worf Had the Flu: His power was close to being gone during his fight with Lute, so he threw it on purpose to gain control over his. The scary part is how he still managed to put up a fight.
The prince of Sforzando and Flute's older brother. Blessed with incredibly powerful magic that could destroy even the most powerful Mazoku in an instant and a kindhearted personality overflowing with compassion for the people of the world, he was considered the savior of humanity for the longest time. However, 15 years before the start of the story his body was taken over by Bass and he is now little more than an extension of the Hell King.
He is eventually freed from Bass' control by Clari, though his magic power almost completely exhausted and on the verge of death. He spends his final moments destroying Bass and reassuring Flute before ascending into heaven alongside his mother.
- All-Loving Hero: He loved everyone, not just Sforzando.
- The Ace: The strongest magic user in existence, as well as beloved by the people of the world.
- Aloof Big Brother: Unwillingly plays this to Flute.
- Anti-Villain: Has no control over his actions.
- Attractive Bent-Gender: During a brief Omake parodying Cinderella where he and the other generals play the ugly stepsisters to Guitar's Cinderella. Guitar and Drum look hideous, while Lute manages to pull it off about as well as Sizer.
- Big Brother Instinct: His love for his sister is so obscenely powerful that it can cause him to breakthrough Bass' control over him for brief instances to save her.
- Big Brother Mentor: Was this towards Clari.
- Big Damn Heroes: Miraculously breaks free from Bass' control to save all of Sforzando at the last minute during the war. Bass is absolutely stunned.
- Chekhov's Gunman: Spends over half of the manga as little more than "the guy who carries Bass around" before we finally learn his identity as Flute's older brother and humanity's former champion.
- Cloudcuckoolander: Thinks that summoning a hungry demon would make a lovely surprise for his baby sister.
- Cross Attack: Wields a cross shaped sword.
- Crutch Character: He was so powerful that humanity essentially relied on him to fight all of the Mazoku for them. When they lost him they quickly fell against the Mazoku forces.
- Curb-Stomp Battle: How he defeats every single Mazoku save Bass.
- Demonic Possession: Bass ripped his soul out and replaced it with a magical orb that allow him to control Lute’s body.
- Determinator: Manages to occasionally break free of Bass' control and help out the heroes a few times despite not having a soul.
- Ditzy Genius: Most definitely a genius, though extremely scatterbrained.
- Does Not Know His Own Strength: Played for Laughs. He accidentally plays rough with baby Flute, hurting her on multiple occasions. If it wasn’t for Queen Horn’s healing magic, she’d be dead.
- The Dreaded: He's known as the man feared by the Mazoku.
- Dying Moment of Awesome: Kills Bass, heals Flute’s injuries and consoles her before ascending to heaven.
- Empty Shell: Lost all of his emotions when he became Bass' puppet and keeps a neutral expression on his face at all times. Averted in a few instances where he sheds a Single Tear or murmurs Flute's name.
- Evil Costume Switch: Switched to black robes after getting possessed by Bass.
- Face–Heel Turn: Against his will.
- Fallen Hero: After Bass defeats him.
- Family Theme Naming: Lute and Flute.
- Fate Worse than Death: Was Bass’ puppets for fifteen years, forced to commit atrocities and hurt the humans he so wanted to save. It's also made abundantly clear that he is aware of everything that is happening but has no control over his actions.
- Friend to All Children: Not just Clari - they all adore him.
- Friend to All Living Things: Played for Laughs. Animals love him so much they pile on him and physically hurt him.
- Fighting from the Inside: Occasionally shown to make sad expressions or even cry. Breaks out of Bass control to save Sforzando during the second war.
- "I Know You're in There Somewhere" Fight: On the receiving end of one against Clari. While he doesn't break free and continues to fight, he sheds tears the entire time.
- Let's Get Dangerous!: He’s sweet, endlessly kind and even ditzy, but when it’s time to fight he’s absolutely terrifying.
- Lightning Bruiser: Fast enough to dodge hundreds of Mazoku attacks at once and strong enough to defeat Drum with a single hit.
- Long-Lost Relative: To Flute. She only learns who he is in the end of the manga, after facing Bass, and Lute dies soon after.
- Magic Knight: Excels in both spell casting and hand to hand combat.
- Meaningful Appearance: Before his turn he wore pure white robes befitting his role as a Messianic Archetype.
- Messianic Archetype: He was the selfless, shining paragon that humanity placed all of their hope into for salvation. Following his defeat, almost all of humankind crossed the Despair Event Horizon.
- Musical Theme Naming: Like the instrument lute.
- Nice Guy: Obscenely nice to the point of hilarity.
- Older Than They Look: Looks maybe a little older than Hamel but has to be in his 30's. Justified in that the Sforzando royal bloodline slows the aging process and his soulless body most likely doesn't age any way.
- One-Man Army: He can take on the entire Mazoku army.
- People Puppets: To Bass.
- Power Degeneration: After fifteen years as Bass’ puppets, he’s running out of magical power and dies soon after breaking free.
- Red Baron: Known as “The Demon of Sforzando”.
- Sacrificial Lion: Humanity basically gave up when they lost him.
- Ship Tease: Sizer playfully kisses him at one point and, despite not having emotions, he blushes. After he dies, Sizer reminisces about how similar the two of them were and makes Raiel jealous.
- The Stoic: After Bass took control of his body he keeps a neutral expression on his face at all times. Averted by his real personality, which was the exact opposite.
- Not So Stoic: Manages to shed a few tears show remorseful expressions and mutter Flute's name a few times.
- Story-Breaker Power: Only Chestra and maybe Vocal could beat him in a fight.
- Warrior Prince: Was essentially humanity's only line of defense against the Mazoku while he was a good guy.
- The White Prince: Before his fall.
Number two Mazoku general, commander of the Dragon Army. He possesses great physical strength and has the temper and bloodlust to match, though his intelligence leaves a lot to be desired. He’s discontent with his position as number two, and is after Bass’ position. He’s defeated by the heroes in the second Sforzando war, and is later killed by Guitar.
He is later brought back to life by Orgel during the final battle, where his body is used as the circle to activate Chestra's magic power.
- Back from the Dead: Resurrected by Orgel during the final battle as a mindless zombie. His body is later used to help Chestra drain the humans of their life energy.
- Big Guy, Little Guy: The big guy to guitar's little guy, though this is proven to be a ruse on the latter's side.
- Blood Knight: The most bloodthirsty of all generals.
- Boisterous Bruiser: Of the evil variety.
- The Brute: The largest of all generals, relies on incredible physical strength, hot tempered and extremely violent.
- Big Guy Fatality Syndrome: Dies long before any of the other generals do.
- The Bully: Kicks Guitar around on a regular basis.
- Carry a Big Stick: His weapon of choice.
- Climax Boss: Fought during the second war of Sforzando and is the first of the four generals to be defeated. However, the story has much, much more left after he falls.
- Dumb Muscle: He’s every bit as stupid as he is strong.
- Evil Versus Evil: He and Sizer can’t stand each other and they fight a lot.
- Hair-Trigger Temper: Gets pissed off very easily.
- Hate Sink: Gets more screen time than the other generals early on to make the audience hate him from the get go. He dies not long after.
- Miles Gloriosus: Considers himself worthy of the title of most powerful Mazoku, and while he does have plenty of power, he's the first of the group to kick the bucket and does so far sooner than any of the others.
- Musical Theme Naming: To go with the general's theme of being named after the instruments in a rock band.
- Our Dragons Are Different: A humanoid, two headed dragon. He's actually made of thirty-two dragons.
- One-Winged Angel: A giant, 32 headed hydra.
- The Rival: To Sizer when she was a general.
- Sir Swears-a-Lot: Provides most of the swearing for the early parts of the series.
- The Starscream: Played with. He wants to be number one general and says so every chance he’s got. However, he doesn’t challenge Bass directly, since he’s too powerful and even Drum isn’t stupid enough to cross him. Instead, he shows off his power in battle, believing it will win him Chestra’s favor.
- Stupid Evil: He’s way too overconfident. That what kills him in the end.
- Super-Strength: Can wreck buildings with a casual gesture.
- Super-Toughness: Took a spell that wiped out a third of his army head on, without even blinking. He even survived being blown to oblivion in Sforzando, and would’ve probably recovered if it wasn’t for Guitar.
- Too Dumb to Live: Sends Guitar’s army away, saying he can destroy Sforzando all by himself. He loses, and Guitar kills him once he’s weakened.
- Wake-Up Call Boss: The first of the generals fought and far stronger than anything the party faced before.
- The Worf Effect: After it takes the efforts of an entire army to defeat him in the main story, Lute is shown to have been able to take him out with a single attack in a flashback to his final battle against the Mazoku.
Number four Mazoku general, commander of the Beast Army. While ranking the lowest among his fellow generals, his army is the biggest and his swordsmanship skills and cunning ways make him a force to be reckoned with.
He faces Trom in the final battle and is defeated. He manages to drink Chestra’s blood and is about to become the new Demon King, but Cornet gets rid of him before he can do anything.
- Almighty Janitor: Initially the lowest ranked of the generals, but ends the story as Chestra's second-in-command after every other member has died- being the pentultimate challenge before Chestra himself and (briefly) the Demon King himself before he anticlimactically is killed off.
- Ambition Is Evil: Easily the most ambitious of the Mazoku and arguably the biggest bastard of them all.
- Arch-Enemy: As their team's respective swordsmen, he and Trom square off frequently. He also seems to take a personal glee in screwing with him and is revealed to have been the one to kill his parents.
- Bastard Understudy: Sucks up to Drum and manipulates him into fighting the battle of Sforzando alone. Once Drum is defeated and weakened, Guitar kills him and absorbs his power. He is later shown to have done the same to Bass and even later proves to have been doing it to Chestra. His only true loyalty is to himself.
- Big Bad Wannabe: Attempts to become the new Demon King by drinking Chestra's blood right after Chestra's defeat. He is immediately stopped by Cornet before he gets to do anything.
- Big Guy, Little Guy: Little guy to Drum's big guy before his death.
- Cannibalism Superpower: Absorbs others’ power by licking their blood. He does it to Drum, Sizer, and even Chestra.
- Chekhov's Gunman: His lower deer half proves capable of functioning independently after Trom bisects him in half and is what allows him to survive their final encounter.
- Combat Pragmatist: Relies on dirty tactics such as blocking attacks with Pandora's crystal to let his enemy's guard down.
- Cool Helmet: He's got a spartan-esque helmet he wears at all times.
- Cool Sword: Owns several, each with different powers.
- Dirty Coward: The moment the odds turn against him, he runs away and he often fights with the enemies handicapped, using hostages, or with overwhelming advantages prior to this.
- The Dragon: Appears to be the most loyal of the generals to Bass. This is proven to be an act shortly after Bass dies where he gleefully mocks him and immediately takes his position as Chestra's number two.
- Dragon Ascendant: Becomes Chestra's Dragon by being the only one of the generals left in the end. After Chestra's defeat, he attempts to become the Big Bad himself, but is immediately stopped by Cornet.
- Evil Counterpart: To Trom. Both are master swordsmen, but while Trom’s strength comes from using his sword for other people’s sake, Guitar uses it to destroy those who oppose him.
- Evil Genius: Uses trickery and manipulation to get the edge on his enemies.
- Evil Gloating: He loves talking his enemies down, particularly Trom whose parents he killed.
- Evil Is Petty: Brutally mocks his enemy's weaknesses while fighting and, when unable to do that, throws petty insults at them.
- Faux Affably Evil: The most polite of the Mazoku generals but is actually the most treacherous of the lot, playing the role of a sycophantic servant while hiding his ambitions to usurp even Chstra.
- Goldfish Poop Gang: Encounters the hero's party far more frequently than any other general, but always manages to survive each encounter. even the last one.
- I Have Your Wife: Threatens Sizer to stop Hamel. When it fails and Hamel corners him, Guitar threatens to destroy Pandora’s crystal. It backfires when Hamel is overtaken by his Mazoku side and proceeds to beat the crap out of Guitar.
- I Shall Taunt You: Mocks Sizer when they fight, calling her a “witch” and “worse than the real Mazoku”. Also does it to Trom when they fight, mocking his resolve and gleefully telling him the gory details of his parent's death.
- Hellhound: His true form.
- Kick Them While They Are Down: Pulls this on Vocal after his defeat, relentlessly mocking and torturing him while keeping him alive only to be used as a sacrifice to the demon king.
- Living Weapon: His howling sword, which is actually a raging wolf.
- Magikarp Power: While he's the weakest of the generals at the beginning, his power-absorbing ability far outstrips even Bass and Vocal in terms of sheer power. By the end he possesses the power of himself, Drum, Sizer and Chestra.
- Manipulative Bastard: Manipulates Drum into getting himself killed to still his power and standing in the army and later manipulates Sizer into being used as a Human Sacrifice to Chestra. He later proves to have been doing this to both Bass and Vocal as well.
- Master Race: How he views Mazoku. Humans who can’t oppose them are to be slaughtered like cattle, and those who try to fight against them are also to be slaughtered because they’re a joke.
- Master Swordsman: Much better than Trom during their first battle.
- Mega Manning: His power allows him to absorb the powers of those he drinks the blood of.
- Mix-and-Match Critters: A dog waist up, a deer waist down. Complete with a deer’s head.
- Not Quite Dead: For several chapters, it seemed like Bass had killed him before he finally reappeared. This happens every single time he seemingly gets killed until the very end of the story where he is killed off permanently.
- One-Winged Angel: His true form is a giant, three headed dog. Thanks to his power-absorbing ability, Guitar combines it with Drum’s own One Winged Angel form and Sizer’s wings.
- At the very end, he briefly combines it with Chestra's power as well.
- Running Gag: Hamel and Trom keep mistaking his deer head for his exposed crotch.
- Smug Snake: Pretty clearly considers himself better than every other general when in reality he relies on running away and kissing up to his superiors to gain more power.
- The Starscream: Acts like Drum's Yes-Man to trick him into getting himself killed to gain his power and position. He later does the same to Bass and even Chestra.
- Trash Talk: When he isn’t being specific, he likes to tell his enemies how ridiculous they are for trying to oppose him.
- Weak, but Skilled: He’s the weakest Mazoku general, but he’s a master swordsman and has an impressive collection of superpowered swords for every occasion. His own special ability is also easily the most powerful of the generals.
- The Worf Effect: If he fights, he's guaranteed to lose, though he always puts on a good performance. Cornet even easily beats him when he gains Chestra's power.
He’s killed by Sizer during the final battle.
- Bulletproof Human Shield: The protagonists are helpless against him because they can’t bring themselves to hurt the dead humans he summons.
- Butt-Monkey: Plays this role to vocal.
- Dirty Coward: When not surrounded by an army, he's quick to cower.
- Fragile Speedster: Can’t take a hit but his speed puts even Sizer to shame.
- Happy Harlequin Hat: Wears a classic jester hat.
- Laughably Evil: Gets played for laughs more than the rest of the Mazoku, though he's still a very real threat.
- Magic Music: Can summon dead people by playing a harp.
- Manipulative Bastard
- Mask Power: Wears a creepy clown mask at almost all times, with the face behind the mask changing whenever he takes it off. It turns out to be his true body.
- Monster Clown: Looks and acts like a clown but specializes in emotional manipulation.
- Mind Rape: His MO is psychological torture, breaking people by exploiting their weaknesses and worst fears. He combines good old manipulation with supernatural means - forcing people to face dead loved ones, or people they killed.
- Musical Theme Naming: Orgel is German for “organ”. In Japanese, it’s a loanword meaning “music box”.
- Necromancer: Can summon and control the dead - specifically, people who died violently or have some unfinished business.
- Night of the Living Mooks: Would rather let the dead do the fighting for him.
- Not Quite Dead: For a few chapters it seems like he was killed by Sizer’s valkyries. The truth is he survived because his body is a corpse, physical damage does nothing to him.
- Not So Harmless: Constantly Played for Laughs but also proves to be a very competent, very real threat to the heroes. He also finally gets out of his role as Vocal's sidekick and turns the tables on him, becoming a major threat once again before his defeat.
- Our Liches Are Different: The real Orgel is the mask, he takes over dead people’s bodies.
- People Puppets: The dead he summons must do his biddings. He can even take their appearance. He’s actually a demonic parasite, his true self is the mask and he takes over corpses.
- Sadist: Mind-rapes people for his own amusement.
- Sensitive Guy and Manly Man: He prefers emotionally manipulating people to their destructions while Vocal just likes to rip them apart.
- Sinister Scythe: Wields a harp/scythe hybrid.
- Teleportation: Uses this to great effect. While he can't physically move as fast as Sizer, after she comes a split-second away from beheading him, he never gives her another chance until the final battle, remaining out of harm's way with Teleport Spam.
- Villain Decay: Introduced as a very serious threat because of his methods and is the villain who comes closest to defeating the good guys, causing Hamel to transform into a Mazoku and almost killing Flute. Once Vocal is introduced, though, Orgel is reduced to his personal punching bag and cheerleader. Ultimately subverted as Orgel is the one who claims Vocal’s soul when the latter dies, and goes back to being a serious threat during the final battle.
- Abhorrent Admirer: Considers Sizer a creature of beauty. It is because of this that he wants to kill her.
- Alas, Poor Villain: Even the heroes can't help but feel sorry for his pathetic state during their final encounter.
- Arc Villain: While a major opponent, most of his actions are contained within a single arc in which he plays a much more antagonistic role than any of the other Mazoku.
- Ax-Crazy: Simplemindedly driven by his desire for death and destruction.
- The Berserker: He lacks any sort of restraint and simply kills on impulse.
- Blood Knight: The only thing he loves more than slaughter is getting to slaughter an incredibly powerful opponent. He agrees to revive Chestra so he can kill him himself and he's eager to fight his son in hopes that he'll be as powerful.
- The Brute: Replaces Drum as this as soon as he appears. He's easily one of the most powerful Mazoku and relishes in causing complete and utter chaos.
- Climax Boss: The last major opponent before the final battle begins.
- Curb-Stomp Battle: The majority of his fights involve him beating the crap out of his opponent. When he fights an enraged Mazoku Hamel he gets put on the receiving end, and receives another one by Orgel in his final moments.
- Demonic Possession: Possesses Sizer's body after his own loses nearly all of its' own.
- Die Laughing: He laughs maniacally as he gets dragged into hell.
- Depraved Bisexual: Flirts with both men and women... while he kills them.
- Don't You Dare Pity Me!: Lashes out at the group for feeling sorry for him as he's dragged off into hell.
- The Dreaded: Even the other Mazoku are afraid of him.
- Dumb Muscle: Not immediately obvious, but Vocal isn't very smart at all. He was completely unaware that he was Chestra's patsy the entire time.
- Evil Counterpart: To both Hamel and Sizer. He and Hamel are both humanoid Mazoku with a rebellious streak and a strong hatred of Chestra, but while Hamel despises his Mazoku blood and attempts to suppress it, Vocal embraces his heritage and uses it to bring suffering to others. Vocal and Sizer had both killed countless humans, but while Sizer regrets it, Vocal revels in it. Sizer hates him for their similarities and even feels she can't be with her friends until she defeats him.
- Eviler than Thou: The other Mazoku find his antics to be going too far, if that's any indication of just how bad this guy is.
- Hellbent For Leather: Wears a tight leather outfit at all times.
- Humanoid Abomination: One of the most powerful Mazoku looks like a punk rock star.
- Humiliation Conga: First Hamel beats him within an inch of his life, then he realizes that he was being manipulated by Guitar the entire time and has what's left of his power drained near completely, but has just enough left over that he has to exist in a childlike form to continue existing. Finally, he has his lifelong punching bag Orgel come in and finish him off once and for all by having all of his former victims drag him off to Hell. Even the heroes start to feel sorry for him.
- In Love with Your Carnage: He's attracted to Sizer because of bloody past, and wishes for her to embrace it once again. He genuinely thinks bringing her back from the dead as a souless killing machine is beautiful and amazing.
- Ironic Death: He's finally killed by Orgel, who summons the souls of all the people he killed to drag him into hell.
- Jerkass: If you think he treats his allies any more than his enemies, you'd be wrong. In fact he kicks Orgel around more than anyone else.
- The Juggernaut: Treated as an unstoppable menace by the cast for most of his run.
- Lightning Bruiser: Moves fast and hits hard. He proves his strength by easily defeating the other resident Lightning Bruiser Sizer.
- Mr. Fanservice: He's a leather clad bisexual Bishōnen who frequently licks his lips suggestively.
- Musical Theme Naming: To complete the theme naming of the generals, he's named after the vocals of a rock band.
- One-Man Army: Stronger than the heroes by a wide margin when using only a fraction of his power.
- One-Winged Angel: Becomes an even more demonic and even more good looking version of himself as well as attaining near godlike power. He only stays in this form for a short time, however, before he uses too much power to maintain it.
- Power Limiter: The ball and chain around his ankle suppresses his full power. It's actually helping him, as once he unleashes his full power he has so little magic left that he almost immediately takes himself out.
- Psychopathic Man Child: Acts more like a rebellious teen than an ancient demon.
- The Rival: Considers himself Chestra's and aims to find one in Hamel. He's willing to mortally endanger nearly all of Hamel's friends to make it mutual.
- Sadist: Enjoys torturing his prey before killing them.
- Self-Disposing Villain: After unsealing his full power, he quickly exhausts what little was left of his magic power, causing him to become an absolute weakling.
- Sensitive Guy and Manly Man: With Orgel. Orgel isn't exactly sensitive, but he relies on emotional manipulation while Vocal uses brutal physical violence.
- Sleep-Mode Size: Forced to enter a child like form after most of his power is used to summon Chestra. He's more or less useless in this form and is sympathized by even the heroes.
- Unknown Rival: Considers himself Chestra's rival. Chestra couldn't care less.
- Unwitting Pawn: Guitar and Vocal had the ulterior motive of unsealing him to use his power to help resurrect Chestra. They intended from the very beginning for him to waste all of his power to the heroes.
- Worthy Opponent: Seeks these out. He considers Chestra to be his only equal and hopes to attain the same relationship with Hamel.
Demon King Chestra’s wife, Hamel and Sizer’s mother. She was the one who opened the box sealing the Mazoku, and for that she was persecuted by humans everywhere. She’s a kind, gentle woman but her harsh life made her paranoid and overprotective of her children. Ten years before the plot starts, she was kidnapped by Mazoku to the northern capital, and Hamel’s goal is to free her.
She’s saved at the end of the manga and reunites with her children. The epilogue shows her living with Sizer and Raiel.
- Adaptation Personality Change: In the anime she's a demure, gentle woman with no quirks whatsoever, while the manga is set up to be this, but is actually a very flawed woman with extreme cases of paranoia that ultimately loves humanity regardless. Also, while manga Pandora despises Chestra and her main concern is her children, anime Pandora loves Chestra more than anything, to the point where the first thing she does after reuniting with Sizer is taking the box containing Chestra back.
- Amazingly Embarrassing Parents: Little Hamel is terribly embarrassed by her paranoid fits. Ten years later, just hearing the stories makes him and Sizer cringe.
- Break the Cutie: Marrying the Demon King, accidentally unleashing unspeakable evil upon humanity and being hated for it wherever you go doesn’t do well to a girl’s mental health, causing her to become insanely paranoid. The paranoia is Played for Laughs.
- Broken Pedestal: Played for Laughs. She’s set up as the ideal mom. Only halfway through the story do we learn how insanely paranoid she really was. When Sizer learns this, she’s devastated.
- Can Only Move the Eyes: She's frozen in the crystal and can't even open her eyes, but if something particularly bad happens to her children, she sheds tears.
- Cloud Cuckoolander: Was convinced that Raiel was only pretending to be Hamel’s friend so he can commit petty crimes and pin the blame on Hamel.
- Cordon Bleugh Chef: Hamel learned from her.
- Crystal Prison: Trapped in one.
- Don't You Dare Pity Me!: Always worries that people hate her and look down on her. Save for Raiel’s parents, her fears are completely justified.
- Elegant Classical Musician: Plays a violin, piano and presumably any other instrument she feels like.
- Fate Worse than Death: Spent a decade trapped in a crystal, unable to move, speak or even open her eyes. She witnessed Sizer's suffering without being able to do anything for her, and had to listen to Bass gloating about whatever bad things happened to Hamel.
- Freudian Excuse: Her irrationally paranoid attitude to everyone that aren't her children is heavily implied to be a side-effect from being emotionally and psychologically traumatized from Chestra, the man she was extremely intimate with, being the Demon King who tricked her into releasing The Legions of Hell under false pretenses, mocking her for falling for his trick, and trying to eat their own children. No wonder she's an emotional wreck.
- Friend to All Living Things: Unless they're Raiel.
- Good Parents: Loves her half-Mazoku children unconditionally, and tries her best to teach Hamel to never hate humans and be a good person who trusts his own humanity. Her paranoid nature compromises the message, but it’s Played for Laughs.
- Half-Human Hybrid: Her mother is a human woman while her father, Old Man Olin, is an angel.
- Heroic Sacrifice: Goes to face Hell’s Army alone to give the people of Anthem time to escape. Unfortunately, they betray her and end up being killed by Bass or Mazoku Hamel, making it a Senseless Sacrifice.
- Incorruptible Pure Pureness: Zigzagged. She’s kind and pure when she’s not having a paranoid panic attack.
- Living Emotional Crutch: Was this to Hamel in his childhood, being one of the few people who defended him and showed him kindness. Her being kidnapped triggered Hamel transforming into a Mazoku and killing everyone in Anthem.
- Love Martyr: Toward all humanity, while simultaneously seeing the worst in them and believing they're out to get her to far more exaggerated extremes than they actually intend- even benign people. This hypocrisy is Played for Laughs.
- Mama Bear: If she thinks you want to harm her children, God help you.
- Meaningful Name: Named after the mythological Pandora. Though unlike in the myth, this Pandora didn’t open the box out of curiosity - she did it because her children were held hostage and she thought it was the only way to save them.
- Missing Mom: To both Hamel and Sizer.
- Mood-Swinger: Goes from a kind and gentle to violently paranoid in the drop of a hat.
- Mum Looks Like a Sister: Doesn’t look much older than her children. Justified since she probably gave birth young, spent the last decade frozen in a crystal and her angel blood slows her aging.
- Musical Assassin: Taught Hamel and Raiel everything they know.
- Obnoxious In-Laws: To Raiel in the epilogue. She still suspects he plans to dump Sizer and abandon their baby daughter.
- Parents in Distress: A large part of Hamel’s (and later Sizer’s) motivation to reach Hameln is to free her from the crystal.
- The Paranoiac: Became this as a side-effect of Chestra's psychologically destructive antics, believing everyone except her children to being a threat for any real/imagined reason, cynical of others- believing the worst in their intentions, a Control Freak to her son's life, tends to hold grudges against others, believing everyone is out to get her and her children, and tends to an unintentional Jerkass, while simultaneously loving them unconditionally. This is all Played for Laughs.
- The Pollyanna: Was this before opening the Box.
- Sticky Fingers: Hamel’s kleptomaniac tendencies come from her.
- Tame His Anger: Always told Hamel to never hate humans and trust them no matter what - this was the only way to surpass his Mazoku blood.
- Vague Age: Her age is never mentioned, but she should be in her late thirties/early forties, and looks about a decade younger.
- Would Hurt a Child: Had no problem abusing a four year old Raiel.
- Unwitting Pawn: To Chestra, who tricked her into opening the Box.
He’s revealed to be an angel, Pandora’s father and the legendary hero who first defeated the Mazoku centuries ago.
- Anti-Hero: He has no redeeming qualities, but he's an invaluable ally.
- Big Good: As the original hero and creator of Pandora's box.
- Big Damn Heroes: Arrives to the final battle riding a massive Pandora’s Toilet and sucks in dozens of Mazoku. Then Guitar breaks the toilet.
- Chekhov's Gunman: Appears relatively early on to give Hamel a Midseason Upgrade then disappears for quite a while. Tehn we learn he created Pandora's Box, is the original hero, is an angel, and is Hamel's grandfather.
- Cloudcuckoolander: Thinks that fusing Hamel’s violin with a microwave would make a great upgrade. He also creates a bunch of Mazoku-sucking home appliances, in the same vain of Pandora’s Box: Pandora’s Toilet, Pandora’s Washing Machine, Pandora’s Microwave...
- Crouching Moron, Hidden Badass: Extremely capable when he wants to be, but even in these moments he never drops his goofiness.
- Dirty Old Man: Interestingly enough, however, it's Hamel and Clari that he sexually harasses, not any of the girls.
- Gadgeteer Genius: When he isn’t being an idiot, he makes remarkable things.
- I Was Quite a Looker: Was [[Pretty extremely handsome]] in his youth. After exhausting his power in the fight against Chestra, he turned into a tiny old man.
- Jerkass: Harasses Hamel, teases him, screws with his violin, steals his food and tries to hide behind him when loan sharks come chasing him.
- He is heavily implied to have raped Pandora's mother. This is played for laughs.
- Just in Time: After the heroes defeat Chestra, he comes to give Flute a new box to seal him.
- Luke, I Am Your Father: He’s Pandora’s father. When Hamel and Sizer find out, they’re mortified.
- Made of Iron: No matter what he goes through, he just won’t die. Justified since he’s an angel.
- Miniature Senior Citizens: Even while wearing his tall hat, he’s the shortest cast member.
- Musical Theme Naming: His full name is Vi Olin.
- Nice Job Breaking It, Hero: Created the Daimou Sword, a sword that can cut through anything once it’s powered with a holy soul. Naturally, the Mazoku want to use it to break Pandora’s Box. The result is Flute getting kidnapped, Sizer losing her soul and the seal breaking. The reason Olin made it? He wanted to eat canned peaches but couldn’t find a can opener.
- Obfuscating Stupidity: He’s quite intelligent and sharp… when he feels like it.
- O.O.C. Is Serious Business: Most of the time, he’s a bumbling old man that no one takes seriously. But on the rare occasions he’s being serious without subverting it with a tasteless joke, people listen.
- Plucky Comic Relief: Exclusively a gag character. Even when we learn just how important he is, he's still played almost exclusively for laughs.
- Sacred First Kiss: Took Hamel’s, much to his dismay.
- Stealth Hi/Bye: Tends to pop out of nowhere, usually when he’s the last person anyone wants to see.
- Strong Family Resemblance: In his youth, he looked just like Hamel. Makes you wonder what Hamel will look like later in life.
- Token Evil Teammate: That evil demonic sword the Mazoku want? He made it! He's also more often than not a greedy jerk who annoys everyone around him and makes the normally obnoxious Hamel look good by comparison.
- Took a Level in Jerkass: In his youth, he was prone to giving friendship speeches. As soon as he became an old man, he raped an innocent woman and proceeded to act like a complete jerk.
