[[caption-width-right:350:]]
Mio's father.
----
* ActualPacifist: He's the one who initiated the truce between the Demon, Human, and celestial realms.
* DaddyHadAGoodReasonForAbandoningYou: He hid his daughter Mio among human parents so she wouldn't be targeted as either a hostage or assassination target. Unfortunately, his death transferred his power into her and living like a normal human girl, she had no way of knowing how to handle it, thus making herself a beacon for hostile demon factions.
* DeathByOriginStory: He is killed by Leohart before the beginning of the story. [[spoiler:It turns out he was alive the whole time.]]
* TheGhost: Although his name is often mentioned in passing, he never makes an appearance, not even in flashbacks, although numerous portraits of him do exist, and he gets illustrations. [[spoiler:However, it's later revealed that Ramsus is actually Wilbert in disguise.]]
* TheGoodKing: During his tenure, many of the downcast, discriminated, and decidedly thin-blooded demons finding their way to the Demon world, most of who long ago lost many humanoid traits, found acceptance and equality in his domain and loved his rule as a direct result.
* InterspeciesRomance:
** He married Mio's mother Ashe, who was a human.
** Averted with his SecondLove, Shella, who's a succubus.
* {{Irony}}: [[spoiler:With TheReveal that "Ramsus" is actually Wilbert in disguise, his SourPrude tendencies show that despite being a Demon Lord, he prefers monogamous relationships, with him having a child with Shella sometime after Ashe's death.]]
* MalignedMixedMarriage: While the Demon Moderate faction loved him unreservedly, and for good reason, his wife, and Mio's mother were not viewed kindly. With him being a pure-blood noble, and her coming from Earth, raised as a human, she had to live in a tower most of her life, for her own safety, the simple pleasure of tending a flower garden being her only joy.
* PosthumousCharacter: Though he's assumed dead before the story begins, [[spoiler:it turns out Wilbert actually survived his battle with Leohart and disguised himself as Ramsus]]

->'''Voiced by:''' Creator/HibikuYamamura (Japanese), Creator/MaureenPrice (English)
Maria's older sister, Rukia serves as Ramsus's maid and assistant in the moderate faction.
----
* AdaptationalHeroism: Rukia is much more sympathetic in ''Burst'' compared to her light novel counterpart. Most notably, she has a larger role in the fight with Nebra and Gald's "heroic spirits."
* AttemptedRape: In the first half of Volume 7, after Zest joins Basara's harem, but before Basara's team goes off to Face Leohart in the tournament, she's overcome by both lust and envy due to the fact that Kurumi is Maria's "toy"... er "special friend", and uses magic to both shred Kurumi's clothes and pin her to the ground before sexually forcing herself despite Kurumi's protests. The only reason she stops is that Shella shows up and [[WhatTheHellHero calls out her daughter for her actions at Basara's behest]].
* BigDamnHeroes: She rescues Maria from one of the "Heroic Spirits" that were attacking Wilbert's domain.
* DidntThinkThisThrough: Shella points out, in explicit detail, everything that would have gone wrong had Rukia gone through with her [[DisproportionateRetribution threat to kill Basara]] for complaining about Ramsus's actions towards Mio. [[IgnoredEpiphany Ramsus and Rukia aren't fazed by this at first.]]
* EasilyForgiven: The only reason she gets any leniency in her sexual assault upon Kurumi is that the Demon Moderates faction is desperate for fighting power due to the persistent threat of the Demon Lord and Demon Council factions. Under any other circumstances, she would have been flayed alive, and that's under her own standards, no less.
* {{Flight}}: She can fly in battle.
* FoolishSiblingResponsibleSibling: She's the responsible to Maria's foolish. While Maria gets things done by teasing and tricking people into doing things her way, Rukia is very calm, composed, strict, and straightforward. Neither of them fully discloses their motives and objectives until they've all played out, however.
* JerkassHasAPoint: While it may seem cruel to inflict punishment upon Maria after what she endured in fighting Zolgia, Rukia's assessment that Maria's crushing guilt for betraying Basara would have been worse proves true when we later see Zest going through a similar crisis of faith.
* JerkWithAHeartOfGold: In spite of her cruel actions, she cares for her mother and younger sister.
* {{Meido}}: She both looks and acts as Ramsus's maid.
* MyMasterRightOrWrong: She puts the well-being of Ramsus first and foremost.

* TeleportersAndTransporters: She not only opens the gate between the human and demon realms but brings Basara and co. along for the ride.
* WingedHumanoid: She sports wings when she goes into battle.

The leader of the demon's "moderate" faction.
----
* AdaptationalBadass: In the original light novel, Ramsus had to struggle to take down one "heroic spirit" and risked his life by using his GravityMaster powers. In ''Burst'' he crushes one into a marble without breaking a sweat, by simply pointing his open palm at it and closing his fist.

* AuthorityEqualsAsskicking: He's the leader of the moderate faction and is a capable fighter.

* ReasonableAuthorityFigure: Despite his initial plans to extract Mio's demon power, he is very sound in judgment and is always willing to listen to Basara and his allies, including Jin.
* TheReveal: By the end of the series, it turns out that [[spoiler:his true identity is ''Wilbert'' himself]].
* TheResenter: He resents Mio because the latter inherited Wilbert's power instead of himself, and considers her unworthy of her title or inheritance. No wonder Basara's so upset with him. Fortunately, Ramsus gets better.
* ShootTheDog: He views extracting Mio's demon power as this, given that she inherited these powers from Wilbert. Basara disagreed.
* SourPrude: At first, he thinks that because Mio's in Basara's Master-Servant pact and has a healthy [[TechnicalVirgin almost sex-life]], she isn't fit to rule. [[spoiler:Considering the fact that he's actually Wilbert in disguise, it's a case of him being an overzealous parent.]]

* UnderestimatingBadassery: He underestimated how powerful Mio would be and how she would be willing to risk her life for her family.
* UnwittingInstigatorOfDoom: Him summoning Mio to the demon world gives Leohart the justification he needed to attack the moderate faction, by calling it a clear act of aggression. He even laments his actions while discussing the matter with Jin.

----
* BathtubBonding: She joins Basara in the bath to introduce Zest for the purpose of having Zest enter a Master-Servant pact with him. Being Maria's mother, it shouldn't surprise anyone that [[PowerPerversionPotential she exploits it for her own amusement.]]
