The hero. Haru Glory came from a small island that's referred to as incredibly far out in the sticks and lacks knowledge of most any world history or geographical features. He's incredibly strong willed and noted for having a good heart. He was chosen to be the Rave Master who was to eliminate the Dark Bring.
Took a Level in Badass: Although it cannot be denied that Haru was already a badass in the series' beginning, it's when he believes that his dad is the one who leads Demon Card that he takes a whole new level of badass since he beats King's entire army single-handedly.
Rave's bearer. Plue is a dog(?) with an unknown gender and age who travels with either the wielder of Etherion or the Rave (or both) and helps guide them. He doesn't do much as far as guiding them, but he does occasionally help either Haru or Elie when they're in a tight spot. He came dangerously close to being renamed Shabutaro by Haru and Cattleya.
The main female. Elie is a cheerful amnesiac girl who's just a little off and really likes bugs. She and Haru met in a racing track (a casino, in the anime) where she quickly fell for him because of his kind heart. She follows him around and is revealed to possess the ultimate magic, known as Etherion. She also bears a strong resemblance to Resha Valentine, who passed away fifty years ago, to everyone's continuous confusion.
Meaningful Name: ELIE 3173. It's initially thought to be a test subject mark (humorously, the person who thinks this has a name that flips to make a number too) but is actually the coordinates for her empty grave.
Ms. Fanservice: Lessened once Belinka, Celia and Julia came along and took some of the load off her.
We don't know what he is either, but at least he know he has a family
A strange blue creature originally recruited by Elie to help her and Haru reach the mountain they suspect a Rave stone to be at. He quickly becomes a member of the main cast, and is supposed to be very skilled at map making. His hobby is peeping on Elie. Every other character is better than him.
Normally, I Would Be Dead Now: Being sliced in two does normally kill one. What kind of bizarre natural selection gives someone the ability to become two people after being sliced in two? What kind of bizarre natural selection makes anything like Griff, for that matter.
The Peeping Tom: Downplayed in the dub, where he's more obsessed with Master Plue.
Silver Claimer and Chick Magnet
A silver claimer (someone who can manipulate silver) and former gang leader who teams up with Haru after reuniting with his grandfather. He a close friend of Haru's and one of the more capable fighters in the crew, wielding a spear. He eventually strikes up a relation with one of the Demon Card generals, but it didn't work out.
Originally he was only interested in a challenging fight, and working for King as part of his Quirky Mini Boss Squad in order to find them. Let goes over to Haru's side after being awed by Haru's pure heart and desire to protect the whole world.

Adaptation Dye-Job: In the manga and Fairy Tail crossover his hair is white. In the anime it's blond, so that he could pass as Super Saiyan Goku.
Anime Hair: Super Saiyan 3 style no less, until he became human. Even after he became human,his hair still looks like a Super Saiyan's one.
Badass: A Dragon martial artist who can turn into a bigger dragon if it's necessary. Oh yeah.
Draconic Humanoid: Let, at least initially. All members of the Dragon Race go through a phase where they spend some time in this state, before either conquering or succumbing to their inner dragon. Let conquers his and becomes more human-like in appearance afterward. His former flame, Julia, succumbed, and ended up a full fledged dragon. At least until he cures her.
A penguin(?) who inherited a large sum of money and giant floating casino from his late father. He's dismayed to learn he's been funding a criminal origination and ends up going to Haru for protection when he refuses to continue giving Doryu money. He becomes their first safe magic user after Sieg reveals he has the gift, but he's generally considered useless by the cast.

Let's polar opposite girlfriend. She spent a good deal of time stuck as a dragon under Jegan's control, but once she changes back she joins Haru's team. She's the most violent member of the team, especially when it comes to her boyfriend, but she also takes on a somewhat motherly role. She also really wants Haru and Elie to hook up.
Taking You with Me: Attempted during one fight against an opponent who could turn himself into acid. When her regular attacks don't work, she resorts to throw herself and him out of the airship they were fighting on and tricks him into liquefying that he evaporates into nothing while she fully intended to fall to her death. Luckily a nearby dragon happened to show up and save her.
Wrestler in All of Us: Her style is more akin to grappling rather then martial arts that her boyfriend uses.
Magic Girl No. 2
A sweet, somewhat timid girl who underwent experiments in order to gain Etherion. They failed, but she acquired some powerful magic nonetheless. Her specialty is healing. She was duped into working for Hardner but quickly switches to Haru's side.
Celibate Heroine: She always spurns Musica's advances, which kind of creep her out.
Covert Pervert: Despite having many Proper Lady traits and being a bit shy in general, she certainly isn't above staring intently at Haru's crotch when he gets naked the evening before the final battle.
Cursed with Awesome: Her magic was obtained through rigorous training that they heavily imply was incredibly painful, but her magic is pretty sweet.
Haru's older sister and mother figure. She took over raising him after their dad vanished and their mother left to find him and came back in a body bag. She has little actual role in the series, but is Haru's initial motivation to train and it's implied that she may have forced a little of his nice personality upon him.
The previous Rave Master. He was close to Resha Valentine, the creator of Rave, so when she gave her life or not to make them so they'd work for him. He fought in the war against Dark Bring and failed to destroy the ultimate one at the very end of the battle, leading to Haru having to pick up where he left off fifty years later. He eventually fights Haru at his prime thanks to a potion. He still loses and dies due to its after effects.
The creator of Rave and Plue's original owner who had the power of Etherion. She supposedly died during the Rave's creation ritual. She bears a mysterious resemblance to Elie. It's later confirmed that she and Elie are one and the same.
Your Days Are Numbered: Shakuma planted a curse onto him and chuckled from the shadows as he slowly succumbed to the curse.
Knights of the Blue Sky
Deerhound, Clea Maltese, Master Dalmatian and Alpine Spaniel, the four strongest fighters of Symphonia that assisted Shiba during the war and died. Later they became the Guardians of the Rave stones. Alpine Spaniel is the only one who is still alive.
The first general of Demon Card that Haru encounters. He joined after Haru's father one of DC's founders got him interested, and has a tedious friendship with Gale. He helps out but doesn't seem to want to be included as part of the inner circle. He's also dating Haru's sister.
And Xty something year old smith who originally forged the legendary Ten Powers. When one of his swords was used to slaughter his family he gave up on sword making and became a lapdog for Demon Card. He gets better once Haru reunites him with his not quite dead grandson.
One of the four generals for The Empire who do virtually nothing other than act as Mr. Exposition. Jade stands out because he's the only one that doesn't get killed or turn out to be a mole. He never gets to meet Haru, but spends a good chunk of the story trying anyway. He's also Jegan's older brother.
Spell My Name with an S: Go through the official translation and count the different names and spelling he gets. He's actually called Sieg initially, and they change the spelling on the next page.
The first (and for a long while, only) sorcerer introduced. Sieg Hart is a magic swordsman obsessed with protecting time, which comes from being raised in a town with the same obsession. He's initially introduced as an assassin after both Elie and King, but after Haru stops Elie's Etherion without killing her Sieg has a change of heart and makes it his goal to protect Elie at all costs.
Chronic Backstabbing Disorder: By the end of the series he's been everyone's enemy at some point. It's a little hard to notice because he's usually allied to multiple groups, but Shuda calls him out on it at one point.
Offscreen Moment of Awesome: He has a magic battle that lasts seven whole days. Only the first couple spells and the last strikes of the match are shown.
One-Man Army: When Haja turns his village against him and he escapes. He takes on the whole village by himself. Even better, he did it without a single fatality using nothing but a sword and low magic power.
Post-Victory Collapse: After his fight with Haja. In his defense, he went a whole week without food or water, since it's the most ridiculously long fight in the series.
Trapped in the Past: He stays trapped 50 years in the past after sending Haru and Elie back to the present. He decides not do anything, not even eat, in order to not alter history in the slightest. (Not that he doesn't go and talk to someone immediately after, but at that point he realized he was supposed to, to make history play out the way it did.)
A girl who claims to be descendant of Clea Maltese and the leader of Ray Barrier City. She is actually Solasido's sister. Both of them along with Fua one of the cities warriors assisted the Rave Warriors during the battle at the Tower of Din.
A young mermaid who Haru accidentally rescues while fishing. When trying to repay him she accidentally gets him caught up in a tragedy that has befallen her people. She eagerly follows Haru to rescue the other mermaids and stop Doryu, and turns out to be a bit of a hopeless romantic, loving him while believing they can never be together due to being separate races.
"You've put up a good fight, but for the sake of time you must die"
Sieg's mentor, and the head of the village dedicated to protecting the time stream. He unwittingly abuses his authority by having people go out and kill regardless of how they feel about it. When Sieg shows him that Haja is a traitor he becomes a little less uptight about what must be done to protect time.
A resident kid of Sieg's village who also didn't believe in their mission to protect the timeline by any means necessary. He was chased out because of it but later helps Sieg when Haji manipulates the village to turn against him. After Haji is defeated and the king comes to his senses, he is welcomed back. Later on, he accompanies the heroes in the final battle and proves instrumental in the fight against Juria.
Cattleya's ex-boyfriend. He encountered Haru while preparing to enter a local dance competition with Nagisa (who was under the name of Mika). He is later kidnapped and turned into a cyborg by the Blue Guardians.
Troubled Abuser: Back in Garage Island, he was abusive towards Cattleya because he was bullied.
Why Am I Ticking?: The Blue Guardians plant a bomb in him when they turn him into a cyborg.
Demon Card/Shadow Guard
King (Gale) Raregroove
The leader of Demon Card at the beginning of the series. He used to be Gale Glory's best friend but something came between them. He now causes misfortune wherever he can in an attempt to draw his old friend out and make him suffer.
Daddy Had a Good Reason for Abandoning You: Leaves his biological son to fend for himself at age six and gives his adopted son abandonment issues. In the first case, he didn't realize that Lucia had survived the attack on Demon Card, and was still mourning him a decade later. In Deep Snow's, he failed to properly explain that he was being sent away so he could lead a better life, not because he wasn't wanted.
Revenge by Proxy: Gale told the Imperial where Demon Card's Headquarters is with the deal of taking King alive as prisoner to end his corrupt ways. To his horror, the Imperial killed all the people inside the Headquarters including King's wife and son (presumably). As revenge for it, King broke out of prison and killed Gale's wife, Sakura, in front of him.
Sanity Slippage: What is frightening about Monster Prison, is that it makes the user become a mindless force of savagery
King's son who went Axe Crazy after having a hellish childhood. He took over Demon Card after his father's defeat. He's noted as being something of a slave driver who comes dangerously close to having a god complex, and for offing any subordinate who fails even the slightest bit.
Even Bad Men Love Their Mamas: Despite all but boasting that his father's death didn't affect him, his mother's clearly did. He mentions her death as the first thing to go wrong in his life (while not even touching on his father) and named the final form of his sword after her.
Informed Flaw: Despite this being in his room, he never displays any extreme insanity or evil aside from his desire of nomarlcy of returning the world to its destroyed state, being a Card-Carrying Villain and Jerkass at his worst
Late Arrival Spoiler: One of the biggest plot twists regarding Lucia is that he isn't dead. The reader is even treated to his Start of Darkness several volumes before learning his character exists as more than a one off in somebody else's tragic backstory.
Parental Abandonment: He lost his mother in an attack at age six, and because King didn't know he survived that attack, he was basically left to rot in Mega Unit while his father went off committing random acts of terrorism rather than trying to rescue him.
Sins of Our Fathers: When he was six years old, Lucia was thrown in a maximum security prison as a precaution since his father was the leader of Demon Card. He also believes that his bloodline is cursed because of his ancestor's sin of creating an Alternate Timeline.
Start of Darkness: The loss of his family and being locked up for ten years for no reason other than being King's son.
The second Demon Card general introduced. A silver claimer like Musica. She tries to play up her looks and likes to flirt, though she isn't really interested in most men. She's also fiercely loyal to King, and hates working under Lucia. She eventually does a Heel-Face Turn after falling for Musica.
Kick the Son of a Bitch: Stabbing Sieg Hart, who just got finished with sealing Haru inside of a horribleMind Rape. Her stabbing of Sieg had nothing to do with what he did to Haru, but the audience can't help but feel satisfied nonetheless.
You Killed My Father: Ogre framed her father for the theft of a warship called the Silver Ray, which lead to him being executed. Before she learned the truth, she was under the impression that Musica's mentor Rize did it.
The fifth Demon Card general, who acts as temporary leader in the lull between King an Lucia's rule. He's also Demon Card's primary sorcerer. He's eventually revealed to be from the same origins as Sieg with the same mission, but isn't quite as willing to convert to the light.
He's able to fight evenly with Sieg after he becomes strong enough for a week straight without tiring.
Big Bad Wannabe: Attempts to wipe out every threat to himself in order to rule supreme, yet he is defeated through a stab by a wooden staff.
Dragon with an Agenda: While he is viewed to be the righthand man of King, in reality, he is working with a secret magic society in order to preserve the natural order by taking him and his son down. Hell, even that's not completely true, it really turns out he's trying to wipe both the Demon Card and the magic society he was born in, all so he can rule the universe with his infinite magic.
The sixth, and vain, Demon Card general. Julius has serious moments once in a blue moon, and usually only because the enemy dared to strike him in the face. In spite of his goofy attitude, he's a powerful fighter, and the other generals tolerate his behavior. He seems to be the only general who acknowledges Shuda as an equal.
Voiced by: Akira Sasanuma (JP), Jeff Nimoy (EN)
Affably Evil: Easily one of the nicer people in Demon Card unless you hurt his face, in which case he gets mad only to return to his usual narcissistic nature
Cloud Cuckoo Lander: He's one of the seven evil generals that the cast fights throughout the series, but he's more often concerned with all that is beautiful (especially himself) and can act pretty stupid for as much credit as King gives him.
One of the four generals for The Empire, who defects to Demon Card after Lucia takes over. He's later revealed to be King's adopted son, who was sent away to be "saved from the path of darkness". He has no attatchment to Lucia, but serves Demon Card in order to try to satisfy King.
Improbable Age: Explained away by him aging 2.5 times faster than a normal person, but he was a baby when Emilia and Sakura died. In other words, he's only been alive about ten years during the events of the story. And even if you count him as 25, he's still a 25 year old who was one of the Empire's top generals, despite having no connections to propel him to that point and, at most, eight years to climb the social ladder. (Or three, if you don't want to count the time it would take him to reach a reasonable age to enlist.)
Dark Is Evil: His affinity and power, subverted as well; the reason why the humans abandoned and mistreated him was because non-humans were viewed to be abominations of darkness, which ultimately encouraged him to embrace Sinclaire.
Wound That Will Not Heal: Not on himself. Any wound he inflicts on someone with his Demon Sword will refuse to heal and get progressively worse until midnight.
The leader of the Oni, who teamed up with Doryu to overthrow two other names in the underworld. He's the most heartless of the main villains, and also the most lecherous. He's completely obsessed with power, and doesn't care who he tramples over to get it.
The leader of a criminal organization known as "Blue Gaurdians". After the loss of his wife and unborn child he found an Artifact of Doom that convinced him to forget his misery by making everything simply disappear and merge with Elie to do so.
Time Master: He can use this to make people experience their old injuries and erase his own injuries.
As well as building and plant life.
Villainous Breakdown: Threefold. One during his final fight with Haru when he realizes his Dark Bring power is failing him as it can only heal him so much and be used in his attacks. The second when he sees Endless being pushed back by Ellie and Belnika, denying him his wish to destroy everything because of his painful past memories. And finally, after he's defeated it's revealed that Nagisa, the girl he tortured just for fun, was in fact his daughter who he thought died in the plane crash that killed his pregnant wife.
Haja's teacher whose magic surpasses even his own, he joins Demon Card in order to initiate Project DR. He is also the old king of the Raregroove Kingdom, thus being King's father and Lucia's grandpa.
Eviler than Thou: Haja assumed that Shakuma shared in his ambitions to take over all of existence, he died before learning that the latter was a sadistic monster bent on returning the universe to its previous state
For the Evulz: His reason for causing the Symphonian/ Raregroove war.
The Dragon: Once Lucia scraps all his other minions, Megido especially.
Hoist by His Own Petard: Ashura fights Haru, with the former dominating the fight after his One-Winged Angel due to his Dark Bring nature. Unfortunately, its for those same reasons, he ultimately is destroyed since the latter has the Ten Powers, which is his Achilles' Heel
Horned Humanoid: Both Ashura and Uta, but with the former, it's a major plot point since growing a second set actually increases his powers
No Body Left Behind: Each of the Demon Lords do this as they are defeated, with the exception of Megido, whose body is melted by lava
Oh Crap: All of them when the heroes manage to gain the upper hand. Juria when Belnika attempts to pull a Taking You with Me on her, when Nibel uses forbidden magic to age himself and match her power and realizing Juria has found out her weakness. Uta when Jet reveals he holds the spirit of the Dragon King in him and proceeds to curbstomp him. Ashura when he suddenly realizes Haru's Sword, the Ten Commandments, was made for destroying Dark Bring of which he is made out of. And Megido when Shuda slashes through his Hellfire and him along with it.
Quirky Mini Boss Squad: For the final battle. Gave all the heroes a run for their money that left them near death due to having to use forbidden magic just to even the odds or, at best, severely wounded.
Squishy Wizard: Juria, who has a healing factor and can recover from most heavy damage done to her. However the group she's fighting against (Julia, Belnika and Nibel) realize while her outsides can take a lot of damage. Her insides are vulnerable as her skeleton is made of ice. Once the latter two damage her enough to paralyze her, cue Julia coming in for the finishing blow via Kiss of Death.
L'Tiangle, Rionette, Racas and Ron Glace. Five warriors from other dimensions are brought together by one of King's Dark Brings, the Gate. The guard the Tower of Din as well as being non-humans of unparalleled strength. One, Let, later does a Face-Heel Turn and becomes one of the good guys.
L'Tiangle is voiced by: Katsuaki Arima (JP), Jeff Nimoy (EN)
Rionette is voiced by: Kousuke Okano (JP), Patricia Lentz (EN)
Racas is voiced by: Hitoshi Bifu (JP) Armando Valdes Kennedy (EN)
Ron Glace is voiced by: Souichirou Tanaka (JP) Joe Ochman (EN)
Accent Adaptation: Racas has a Spanish accent, which is very fitting considering his character
Non-Standard Character Design: These five are much more detailed in design, especially compared to the later guardians of the major antagonists who would later appear in the story; especially L'Tiangle, who is noted to be the hardest character to draw in the whole series.
Our Demons Are Different: Like Berial's case, it's not made clear if they are of a separate race from the Demon Lords' race; but it's clear that each of the members come from different types of Demonoid, with Ron and L'Tiangle being Animated Armor, Rionette being a tall blue creature with a long neck, skinny arms, and a tail coming out of its back and Racas being a yellow, segmented pointy eared humanoid
Villainous Breakdown: L'Tiangle, once Musica gets ahold of him, immediately panics as he did not expect that he'd make a counterattack.
We Hardly Knew Ye: With the notable exception of Let, the rest of the guardians are taken out before we learned anything major about them.
A minor character who plays the Straight Man to Nakajim in the Flash Forward mini-strips "Levin Minds the House". Levin is left by his parents in the care of the strange creature Nakajima. The question of his parantage is supposed to keep people in suspense. He's (spoilers) Haru and Elie's son.
We don't know what he is, but there's a lot of them
A strange plant person who grows on Haru's house. He's some sort of bizarre insectivorous sunflower, but even though he's a plant he refuses to admit this. In the side-comics, he babysits Levin, mostly via tormenting him.
Voiced by: Kosuke Okano
Bizarre Alien Biology: He can move only when others don't see him and can reproduce asexually despite having parents.
Offscreen Teleportation: His species are immobile legless plants but live in a normal-looking village affixed to houses and manage to go about normal human lives, but only offscreen, with no explanation about how they do it.
