Fugil Arcadia

Fugil Arcadia

Drag-ride: Ouroboros

Voiced by: Ryōta Ōsaka

The First prince of the Empire. The original user of Bahamut.

---

• Achilles' Heel: He spent most of the series manipulating the Paladins into placing the Ragnaroks' Grand Forces into the Ruins, all to set up <Endless>. If even one of these Grand Forces is removed, <Endless> becomes less effective at tricking the masses.
• Actually a Doombot: In Volume 16, Lux seemingly defeats Fugil in a duel, but it turns out to be a fragment of Sacred Eclipse wielding a copy of Bahamut. Unlike most examples, Lux is aware of this from the start and sees it as an opportunity to jog his memories and practice for when he has to fight the real Fugil.
• Adaptational Villainy: The anime has far less hints of his obsession with heroism and makes him seem like a standard Card-Carrying Villain who acts only for his own amusement. While Fugil's light novel version occasionally complimented Lux's combat ability and often brought up valid points to debate him, the anime version mainly repeats cryptic lines about Lux being the weakest.
• The Ageless: He received more than Elixir than a human should be able to handle, but he somehow mutated and survived. As a result, he no longer ages and doesn't need cold sleep like the Holy Arcadia princesses.
• Alas, Poor Villain: Despite all his manipulations, Lux feels sympathy for him because he had a noble goal but lost sight of it due to seeing the dark side of humanity, saved Lux in the past, and was unknowingly fighting for a hopeless goal for millenia. Fugil's only consolation is that his and Arshalia's mercy towards the traitor clan was not in vain, since Lux, who is descended from the clan, tries to save others in turn.
• All Your Powers Combined: Ouroboros has an armament, Infinity, which can take the form of any Divine Drag-ride. This explains why he was able to casually give away Divine Drag-rides to other characters without fear.
• An Offer You Can't Refuse: He has Lux initiate the coup because if Lux does not, Philuffy will wind up being experimented on, against her will. Victims of those experiments are never whole again, those that actually survive, that is. Unfortunately, his intel was wrong and Lux breaks down in grief upon seeing Philuffy's corpse, forcing Fugil to use <Endless> to erase Lux's memory and make him think Philuffy was spared from the experiment. It's unknown if Sacred Eclipse reviving Philuffy was also part of his plan to keep Lux from realizing the truth.
• Anti-Magic: At one point, he wields a copy of Typhon, and he's capable of using <Missing Faith> to negate his opponents' Divine Raiment without difficulty.
• Arch-Enemy: His betrayal of Lux hit the latter hard and caused him to have issues accepting the affection of others. He continues to antagonize Lux by aiding almost all of the antagonists in the series.
• Back for the Finale: Shows up in the royal courtyard near the end of episode 12, in such a way that Lux can't help but see him, before slinking off again into the shadows.
• Bad Guys Do the Dirty Work: He killed the Imperial Court and the Empire's Drag-Knights during the coup.
• BFS: Exaggerated. His Ruin-sized Ouroboros wields a proportionally sized sword with surprising accuracy.
• Big Bad: Double subverted. At first, he appears to be the main villain who used Lux and the coup for an unknown agenda, only for him to be revealed as The Dragon to Listelka. In Volume 14, he kills Listelka and is only minutes away from taking full control of Avalon. He's also responsible for leading the traitor family to victory in their rebellion against the Lords and for saving the surviving Lords, meaning he's the Man Behind the Man to both branches.
• Big Sleep: At one point, he went through a strenuous Baptism to gain the ability to control Ouroboros, putting him in a coma. This prevented him from saving Arshalia from their "allies."
• Bitch in Sheep's Clothing: While training with Lux, he played the part of a supportive older brother, only to reveal his true colors as a murderous terrorist by killing the Emperor.
• Black-and-White Insanity: Subverted. Despite his belief that he's the one true hero and that Lux's ideals are foolish, he also acknowledges that he can't consider those ideals evil. He states that many people means many forms of justice, and people come into conflict because of ideals that they can't concede and because they need to protect themselves and their loved ones.
• Bright Is Not Good: His Ouroboros is a massive, white-colored mecha and he was known as the White Hero to the Arcadia Empire.
• Can't Kill You, Still Need You: He has started rebellions against multiple generations of both Arcadia families, but he always ensures that there are survivors on both sides because he needs them to use their bloodline-induced authorization in the Ruins.
• Card-Carrying Villain: Zigzagged because he sees himself as Necessarily Evil. He refers to himself as the villain who betrayed Lux and advocates being The Unfettered, but he also considers himself a hero and laments he can't find any other people who share his ideals.
• Charles Atlas Superpower: According to Volume 16's epilogue, Fugil had abnormally high constitution before receiving full-body Baptism. His natural constitution is a prerequisite to survive Baptism of that scale. This works against him; his endurance is superior to a Drag-Ride and he has high pain tolerance, making it hard for him to assess damage to his own Drag-Ride.
• Chronic Backstabbing Disorder: The only allies he hasn't betrayed so far are Automaton!Arshalia and Sacred Eclipse. While he betrays Lux and Listelka for not living up to his ideology, his allies who do play by his rules aren't safe either, as shown when he neglects to tell Raffi that Sacred Eclipse will eventually kill her. He claims that as the "Hero of the Beginning," there's no such thing as a true ally for him, including the Automata.
• Curtains Match the Window: Like all members of the Imperial family.
• Dark Messiah: He wants to maintain peace and balance in the world, and his allies see him as a hero who can save them and help them achieve their ideal utopia. He uses <Endless> to brainwash the population into going along with his current ally while they eliminate any threat to the new regime. What his allies don't realize is that Fugil also intends for them to eventually lose control of Sacred Eclipse and kill themselves along with the majority of all countries' top Drag-Knights, leading to all countries starting from square one in terms of military power, thus leading to "balance."
• Dragon with an Agenda: Lux accuses him of secretly using the Holy Arcadia princesses for his own ends, despite his supposed subservience to them. This turns out to be true when he kills Listelka. Even when his allies go along with his ideals, he acts behind their back by saving their enemy, under the rationale that he can't allow his allies to have too much of an advantage over their enemies.
• Dual Boss: His true method of fighting is to have Automaton!Arshalia control Ouroboros's main body while he fights with a copy of Bahamut. This is because Ouroboros is so big that it has trouble fighting smaller enemies that are too close to it, requiring Fugil to fight off those enemies with a normal-sized Drag-Ride.
• Enemy Mine: Despite working with Hayes and disagreeing with Lux's ideals, Fugil still gives him advice on how to free Philuffy from the former's grasp. This is because Hayes is deviating too much from Listelka's more cautious plan to take over the world.
• Evil Counterpart: Like Lux, he's a prince of a corrupt empire and is capable of piloting Bahamut despite being a male, but he's a misanthropic Knight Templar who believes no sacrifice is too great to Pay Evil unto Evil while Lux is a Knight in Sour Armor who wants to resolve problems without sacrificing innocents or killing enemies. At one point, Lux admits he would have ended up a misanthrope if it weren't for Philuffy and her family, meaning he could have turned out as bad as Fugil. Finally, Fugil's usage of the Infinity armament favors Bahamut over all other Divine Drag-rides, showing that he's meant to be Lux's counterpart in combat as well.
• Evil Wears Black: He's the original owner of the black-colored Bahamut and despite having Ouroboros, a white-colored Divine Drag-ride, he prefers to use its Infinity armament to wield a copy of Bahamut. He also turns out to be the one mostly responsible for the legend of the Black Hero, but used <Endless> to embellish Lux's role in the coup and downplay his own.
• Explosive Overclocking: While many Drag-Knights can use Over Limit to power-up their Drag-Rides at the cost of putting them under strain, Fugil's Baptism allows him to use Over Limit more effectively due to his high durability and pain tolerance. Worse yet, he can make Ouroboros's main body enter Over Limit by taking in the central part of Avalon.
• Fallen Hero: According to the Sacred Eclipse Ragnarok, Fugil used to have similar ideals as Lux about selflessly protecting friends and foes before becoming cynical.
• Faux Affably Evil: After being outed as a villain, he occasionally showers Lux with compliments just like in the past. Part of it is Villain Respect and part of it is to subtly mock the latter for being tricked by the "big brother" act. In Volume 8, he sarcastically claims that he'll cheer for Lux's righteous ways and that the latter will succeed in avoiding betrayal this time.
• For Great Justice: During his final battle, he claims he'll carry out justice and that Lux's justice is insufficient because his methods are too soft.
• From Nobody to Nightmare: He was once a commoner who risked his well-being for cats and dogs before being recruited by Arshalia Rei Arcadia. As Arshalia's servant, he became a skilled Drag-Knight, but was still just as susceptible to injury as everyone else. After repeatedly applying Baptism and gaining control of Ouroboros, he becomes a nigh-immortal Ace Pilot trying to reform the world via perception manipulation.
• Go Out with a Smile: As he dies, he's content that a hero, Lux, came about as a result of Arshalia's mercy towards the traitor clan.
• Hero Killer: He kills Singlen and Magialca in Volume 15. Though the latter survives.
• Heroic Resolve: One of his genuinely useful pieces of advice to Lux is that if he's fighting to protect someone or something important, his determination will let him surpass his limits. Unfortunately, Fugil is a Knight Templar for Arshalia's vision, which means his belief in this trope makes him a very dangerous villain.
• Hidden Agenda Villain: While he does have a past as a Fallen Hero, it's ambiguous whether he's acting For the Evulz, for the Holy Arcadia Empire, or for something else entirely. Volume 15 confirms that his goal is to keep using Avalon and a hero to act as its core in order to restore the world's balance.
• Humans Are Bastards: He claims that all "heroes" merely fight for their own self-interest at best. This might be why he considers Lux's altruistic motives and mercy to be a sign of weakness.
• Humans Are Insects: According to Mishis, Fugil only sees other people as equivalent to fish in an aquarium. While he wants to lead them to peace, Magialca notes that his methods ultimately treat them as objects to be controlled rather than sentient beings.
• Humongous Mecha: According to Lux's flashback, Ouroboros is bigger than the empire's castle. Volume 15 reveals that Avalon is a part of Ouroboros and that Ouroboros is the true Ruin, being a machine that doubles as both a Drag-ride and Ruin. He can either pilot the mecha directly or put Automaton!Arshalia in charge of it while he pilots a Divine Drag-ride copy.
• Hypocrisy Nod: During the revolution, he wants to kill the Arcadia imperial court in order to protect the weak from them, but Lux points out that this makes him the strong one killing the weaker imperials. Fugil admits to Lux's words, but he considers this action necessary because he doesn't think the court will redeem themselves.
• Hypocrite Has a Point: While a lot of his words about human nature make sense, his claims of saving the weak fall flat when he has Singlen's sister killed in order to force him to become a "hero," despite how she's indicated to be a harmless civilian unlike most of Fugil's other victims.
• I Did What I Had to Do: He justifies his murder of the imperial court not just because of their evil ways, but because the rebels' plans were leaked and Count Atismata got assassinated. The empire already started spreading news to the masses that the revolution failed, meaning it would be impossible to dethrone the emperor without killing him.
• It Amused Me: Some of his actions seem to be more for his amusement than anything practical, as shown when he gives Tiamat to Lisha despite how she could use it against him someday. Not to mention that many of the villains he helps never seem to get enough help to actually take down Lux, who he spared on multiple occasions. Though given the scope of his plans and how he needed Lux as a pawn, this could be subverted.
• Jerk with a Heart of Gold: In the past, he still had an air of cynicism, but was also altruistic enough to protect cats and dogs from citizens who wanted to vent their stress, even if it meant getting beaten up in the animals' place. Arshalia recognized that he was benevolent, and recruited him to help her bring peace to the world. Unfortunately, he Took a Level in Jerkass due to his bitter experiences as a hero, constantly witnessing the dark side of humanity and losing Arshalia.
• Jerk with a Heart of Jerk: Towards anyone who isn't Arshalia. Anytime he seems to show sympathy towards someone's plight or tells them they have potential as a ruler, he still sees them as a disposable pawn. Even when he saves Raffi and helps her maintain her rule, he still has her fuse with Sacred Eclipse knowing that she'll be consumed by the Ragnarok in mere months.
• Karmic Death: Many of his manipulations result in his pawns crumbling to dust from either overdosing on Elixir or fusing with Sacred Eclipse. After Lux deals him a fatal wound, Fugil crumbles to dust.
• Kick the Dog:
  • In Volume 4, he mocks Lux for being someone who wasn't loved by anyone. Whenever he and Lux meet, he usually finds a way to reopen the old wounds of the coup.
  • Having Singlen's innocent sister killed just to motivate a single person into becoming a hero is one of his worst actions, especially considering that Sacred Eclipse could have found a different potential hero who was more willing to work with Fugil.
• Knight Templar: In Volume 3's prologue, he tells his maid that he's a true hero and that his manipulation of various factions is necessary to open all the ruins. In a flashback of their duel, Fugil offers Lux to become a ruthless "hero" alongside him. In Volume 14, he claims that his mission is to preserve the balance between world powers and to be an ally to the weak, even if it means betraying factions that he once saved from persecution. He seems to be sincere about this, since he expresses these beliefs while he's alone with Listelka, who he mortally wounded.
• Last Villain Stand: In Volume 19, Fugil is left with a damaged Bahamut copy and Ouroboros's main body is destroyed. On top of that, Lux and the AI version of Arshalia tell him that his mission is impossible because of Sacred Eclipse's inherently flawed design. He still continues fighting Lux until he dies because he can't think of any other solution to balance the world and because he doesn't think Lux is qualified to be a hero.
• Laughing Mad: He breaks out in hysterical laughter in the anime after having killed the entire imperial court, while Lux was busy fighting the 1200 drag knight bodyguards outside.
• Lightning Bruiser: Ouroboros is alarmingly fast and accurate for a Ruin-sized mech, as shown when its sword swings easily catch the Paladins off guard. This is because Fugil can apply <Reload on Fire> to it, allow it a brief period of time where it can move faster than usual.
• Love Makes You Evil: He was saved by Arshalia Rei Arcadia and received her trust, causing him to do anything to realize her vision. Unfortunately, he also holds a grudge against humanity for betraying her despite her good will towards them.
• Loving a Shadow: One his his main flaws is that he excessively idealizes Arshalia as a pure-hearted martyr whose only flaw is being too merciful, and therefore believes her plans involving Sacred Eclipse and Avalon can't possibly be wrong. Her digital ghost points out that she was ultimately a flawed human like everyone else, and that she slowly became more villainous in her desperation to end her family's conflict.
• Misanthrope Supreme: There's no telling what level of atrocity he's witnessed over the centuries, but he's come to wholly believes that humanity is inherently evil incarnate, only prancing around behind masks of virtue, and that Avalon is necessary to force them in the right direction.
• Misery Builds Character: He believes people who have experienced personal tragedy to be the best candidates to help him rewrite the world, since their wish to change the world will be much stronger. Unfortunately, he has no qualms about creating these tragedies, as shown when he arranges for Marche to get killed in order to make Singlen more ambitious.
• Moral Sociopathy: He is devoted to his ideals of balance and heroism as he defines them, but cares absolutely nothing for human lives. Even when he saves others, he does so based on pragmatism and principle rather than actual care. However, he doesn't tick all the boxes for sociopathy, since a true sociopath wouldn't have deep enough feelings to get Sacred Eclipse to transform into a loved one.
• Neck Lift: The manga has him lift Lux by the throat while berating him for "not being evil enough," and for no discernable reason. Given the flashbacks of him fighting Lux in the light novel, this may have been after he won their duel.
• The Needs of the Many: He advocates this to Lux in Volume 4, claiming that by trying to save Philuffy, he's putting the country and other students at risk. This also seems to be the reason he turned on the Emperor and Listelka. While he doesn't disagree with their ruthlessness, he still holds them in disdain for not seeing the bigger picture beyond their inner circle of elites.
• Nerves of Steel: Baptism is more painful the more of the body is subjected to it. Simply applying it to the eye is painful enough according to Aeril, but Fugil had the operation applied to his whole body. Additionally, while his Baptism allows him to heal from wounds, they don't prevent pain, yet he bounces back whenever the heroes manage to actually deal flesh wounds that would knock anyone else unconscious.
• Nice Job Fixing It, Villain:
  • Every time he encourages an antagonist, or provides his aid in one form or another, it always ends up as him giving them exactly what they ask for, enough rope to hang themselves, and they invariably do. His Psychotic Smirk on every occasion suggests this is intentional.
  • Double subverted when he gives Bahamut to Lux and Tiamat to Lisha. Since he has the Infinity Armament, he loses nothing by giving Divine Drag-rides away, but in Volume 19, Lisha uses Tiamat to break Ouroboros in half and Lux defeats Fugil with Bahamut.
  • Volume 14 reveals he applied Baptism to Lux, allowing the latter to use Bahamut longer, use Over Limit, and safely absorb Elixir from Sacred Eclipse. This ends up saving Lux when Singlen deals a fatal blow to him. This also allows Lux to eventually resist the effects of <Endless> and realize Fugil won the battle for Avalon.
  • He inflicts several memory resets on the entire world, leading to Lux confessing to a different heroine in each loop. This causes the Battle Harem to agree to have Lux Marry Them All.
• Not Me This Time: When Lux learns that the Arcadia remnants have an Abyss flute and sees a cloaked figure backing Saniya while using a flute, he immediately assumes that figure must be Fugil and that he's behind the Arcadia remnants. That figure turns out to be Hayes, who is associated with Fugil, but is using the Arcadia remnants and Heiberg for her own agenda. When confronted by Lux, Fugil states that Hayes is acting in a way that's inconvenient for his plans.
• Not So Invincible After All: AI!Arshalia admits she has no idea how to beat Ouroboros and believes Fugil is invincible. Lux asks her for more information anyways because Fugil himself taught him that there's no such thing as an invincible foe. During the final battle, Ouroboros struggles against the Paladins when they take advantage of its size to avoid its attacks. Fugil, despite being the physically strongest character, fails to notice damage to his Bahamut precisely because of his enhanced pain tolerance, leading to his defeat.
• Obfuscating Disability: The first volume states that he had to retire from being a Drag-Knight due to an injury, which is a lie to make others underestimate him.
• Offscreen Moment of Awesome:
  • In Volume 5, Lux's Laser-Guided Amnesia eventually gives way to memories of him dueling Fugil. Given that Fugil is still at large and that Lux ended up with amnesia in the first place, it's obvious that The Bad Guy Wins.
  • According to Arshalia's memory, he went through many battles to stop crimes against humanity in his era.
• Pyrrhic Victory: He already tried to use Avalon to manipulate humanity several times, but the peace he creates never lasts before whoever he propped up as the leading world power turns corrupt too, forcing him to try again. He also didn't realize that Sacred Eclipse was unfixable no matter how many virtuous people he attempts to fuse with it.
• Pragmatic Villainy:
  • He admits that he could have used the Abyss flute to destroy the empire's army without Lux's help, but the resulting damage would be bad for later stages of his plans.
  • He tries to talk Hayes out of attacking Atismata because doing so will supposedly decrease her lifespan and make her less useful for future plans.
• Psychotic Smirk: Sports these all the time. It seems to be literally impossible for him to leave a scene without sporting one.
• Reality Warper: His Divine Raiment, <Endless>, can establish worldwide rules such as preventing people from leaving a building, preventing people who aren't using Drag-rides from being perceived, preventing indirect attacks, etc. It can also perform perception manipulation on a wide scale and affect people's memories, which can be used to create a "Groundhog Day" Loop.
• Really 700 Years Old: He was alive at least around the time of Sacred Eclipse's creation and personally knows the three Holy Arcadia princesses. When Lux sees a flashback of Sacred Eclipse's creator performing Baptism surgery on Fugil, he suspects that Fugil predates the Holy Arcadia princesses too, since Listelka claims that Sacred Eclipse was created before her era.
• Safety in Indifference: While he initially wanted to retain his humanity after going through full-body Baptism, he's presented with Arshalia's mangled corpse, causing him to accept being heartless as a defense mechanism.
• Secret Test of Character: His usage of Sacred Eclipse is a brutal example of this trope. He's looking for someone worthy to become the most powerful ruler in the world, but the testing doesn't end there. He's also trying to see if there's anyone who can maintain their sanity and stay true to their ideals while fused with Sacred Eclipse in the hopes that they can use the Rangarok's power properly, and no one has ever succeeded.
• Self-Made Orphan: Killed his father, the Emperor, during the coup. Subverted when it's revealed that he isn't in Lux's generation and is actually older than the Emperor.
• Shadow Dictator: Subverted. While he backs rulers who are chosen by Sacred Eclipse, Lux notes that Fugil doesn't give them direct advice for making policy and instead lets them come up with their own ideas.
• Silly Rabbit, Idealism Is for Kids!: He tells Lux that his attempts to avoid sacrificing innocents or enemies will just result in more betrayal. He gets this thrown back in his face by Singlen, who points out that he'll never be able to force the world to accept his impossible ideals.
• Strong and Skilled: His body-wide Baptism and his overpowered Divine Drag-ride already make him nearly impossible to defeat. He also has all of Lux's techniques and shares his student's penchant for coming up with game-changing tactics on the fly. The skilled part gets downplayed because while he does have over a thousand years of experience, his Baptism-induced durability causes him to neglect damage to his Drag-Ride and fight less carefully than he should.
• Superpowered Evil Side: He had Baptism applied to him by the Lord who created Sacred Eclipse and Ouroboros.
• The Svengali: He only taught Lux how to pilot a Drag-ride in order to use him to take out the Old Empire, making it easier for the Holy Arcadia princesses to take their place. Given that he passed up several opportunities to finish off Lux himself, he's still not done manipulating his former student. This is downplayed because he once believed that Lux would see things his way and become a willing protege.
• Teach Him Anger: He tried to push Lux into killing the imperial family in order to demonstrate his resolve as the land's new ruler.
• Teeth-Clenched Teamwork: The only person who trusts him is Listelka while all other members of their faction are suspicious of him and only put up with Fugil to reach Avalon.
• Threat Backfire: Singlen tells him to go to hell, only for Fugil to remark that his centuries of balancing the world is already hell.
• Transformation Is a Free Action: Averted. When Ouroboros initiates its own Over Limit, the process takes a long time due to its size. Fugil and Automaton!Arshalia attempt to get around this by setting an <Endless> rule where all attacks cause the attacker to receive twice the damage, knowing that any attack that could seriously damage Ouroboros during the transformation would kill the attacker. They didn't expect Lisha to launch her strongest attack anyways.
• Trickster Mentor: Aeril speculates that Fugil already invented all of Lux's techniques a long time ago, but never directly taught them to the latter. Instead, he taught Lux in a way that would allow him to reinvent the techniques.
• Villain Has a Point:
  • As dickish as he is, he's not exactly wrong about Lux being betrayed by the people he saved, as shown by how Lux was placed into Indentured Servitude by the kingdom, which wouldn't exist without him. He also points out that they'll try to manipulate him with too-good-to-be-true offers, which is exactly what they attempt to do when the politicians offer to "free" Lux from indentured servitude and make him a noble, all to make him indebted to them in a different way. He also points out that the oppressed masses aren't so innocent, as shown when their treatment towards Lux and his dying mother.
  • After meeting Hayes and seeing the situation in Heiberg, Lux had no choice but to admit that Fugil had a point about not being able to save all enemies. Though this point is downplayed because there are situations where simply killing the enemy for their crimes can backfire, as shown by how the King of Vices wanted him to kill Rosa in order get an excuse to go to war with the New Kingdom.
• Villain Respect:
  • Zigzagged. He acknowledges Lux's ability as a Drag-Ride pilot and is usually less surprised than most antagonists whenever the latter wins. He's also impressed when Lux manages to get Aeril to pull a Heel–Face Turn and states that Lux has a knack for gathering allies. On the other hand, he considers Lux "the weakest" for refusing to cut down his enemies for the greater good. This is eventually played straight once Lux defeats him and attempts to save him, causing Fugil to acknowledge him as a hero.
  • He compliments the Paladins for taking down seven Ragnaroks with equal numbers, a feat that was considered impossible in Listelka's era.
  • He compliments Singlen for having the will to reform the world, so much that he thinks Singlen might gain Sacred Eclipse's favor in place of Raffi. He also considers Singlen enough of a threat in combat that he made sure to kill the latter.
• Villainous Rescue:
  • During the revolution against the Old Empire, he saved Airi from being used as a hostage against Lux.
  • When Yoruka is wounded by Yos Tork, Fugil has Automaton!Arshalia heal her despite how she found Avalon's location. He does this because Queen Raffi has too much of an advantage against the Azure Division.
• Virtue Is Weakness: Lampshaded and played horrifically straight. Fugil condemns Lux as a pathetically weak opponent because Lux is not a cold and calculating Knight Templar who treats his friends, love interests, and subjects like disposable tools. This is because Arshalia was betrayed by the people she saved, and he believes the same thing will happen to Lux.
• Xanatos Speed Chess: Surprisingly, he didn't expect the plans of the coup to leak to the Emperor and for Count Atismata to get killed, so he decides to improvise by killing the entire imperial court and trying to convince Lux to ascend to the throne. When that doesn't work, he allows Raffi to take the throne instead, and then teams up with her after he betrays the Lords. In general, his plans are flexible due to having multiple potential "heroes" for Sacred Eclipse.
• Was It Really Worth It?: After Arshalia was killed by the traitor clan that she saved, Fugil questioned if her decision to help them and believe in their inner goodness was a mistake. When the traitors' descendant, Lux, attempts to save Fugil despite the two being enemies, Fugil concludes that she wasn't mistaken.
• We Can Rule Together:
  • In Lux's lost memory, Fugil actually offered to let him in on his true plans, stating that they had to fulfill their mission as "heroes". He seems genuinely surprised and disappointed when Lux rejects him because he believes that they're not that different, which may explain why he's much more dismissive of the latter in the present.
  • He offers to spare Singlen and allow him to retain his memories in the remade world, allowing the latter to rise to power and possibly get chosen by Sacred Eclipse to influence the world as he sees fit. Singlen pretends to accept in order to launch a surprise attack on Fugil.
• Weapon Tombstone: After he crumbles to dust, Ouroboros's sword device falls tip first into the ground and acts as Fugil's gravestone.
• Weaponized Teleportation: Ouroboros's second armament, Zero One, can teleport a target to a secret room in Avalon and return them a moment later. Targets can include the user, other pilots, or energy attacks from Drag-rides, though like <Divine Gate>, there's a mass limit.
• Well-Intentioned Extremist:
  • Played with. His goal of establishing a just world order sound good on paper and he's opposed to outright malicious people like Listelka and Diseld ruling the world. On the other hand, he doesn't have much empathy for the masses he's trying to protect and his use of <Endless> means he's establishing regimes based on lies. However, Automaton!Arshalia claims that there were many regimes that couldn't be overthrown without Fugil and Ouroboros's power and if Fugil is defeated, such regimes could become unstoppable.
  • His plan to change the world involves finding someone else who is this trope. He states that Listelka has the resolve to do anything to achieve her goals, but ultimately finds her too selfish to care about the welfare of the masses. He recognizes Lux has benevolent goals and the ability to gather allies, but he also considers the latter too merciful to make necessary sacrifices. He eventually settles on allying with Raffi because she's willing to use <Endless> and kill political enemies in order to maintain order in Atismata.
• White Hair, Black Heart: Lux's evil older brother also has silver hair.
• Yes-Man: Listelka sees him as this, since he never expresses any disagreement towards her actions and goals until he kills her.
• You Have Outlived Your Usefulness: He kills Listelka after she paves the way for completing the third trial of Avalon.

Hayes Vi Arcadia

Hayes Vi Arcadia

Drag-rides: Nidhogg, Fernyiges (autonomous)

Voiced by: Hisako Kanemoto

A blackmarket dealer from the Heiberg Republic. She is later revealed to be the third princess of the Holy Arcadia Empire.

---

• Ambiguously Human: When enraged, or stressed, her face begins to literally crack with Tainted Veins crawling forward from her ears to her eyes. This is revealed to be a result of her Baptism.
• Asshole Victim: Listelka forces her to kill herself after she outlives her usefulness, which isn't exactly sad considering the latter's increasingly vile actions throughout the series.
• Ax-Crazy: She shows glee in causing chaos and destruction with her Abyss and Ragnaroks. When her plans encounter setbacks, she snaps and promises to double down on whatever destruction she already caused just to spite those who piss her off.
• Bad Boss: Hayes despises Fugil despite all the work he does for the Holy Arcadia princesses, out of a combination of valid suspicion and hatred towards his bloodline. Fugil states that he'd have no value as a hostage to her, meaning Lux's attempt to capture him is pointless. When Fugil and Mishis give her valid warnings against attacking Atismata without waiting for better circumstances, she tells the former to just work like a slave and die.
• Bad Guys Do the Dirty Work:
  • Is shown killing Kreutzer for outliving his usefulness.
  • She kills Velvet Barth in prison because he saw her meeting with Kreutser.
  • She kills Zweigbergk in order to test her new Sacred Eclipse powers.
• Boyish Short Hair: To go along her short hair, she looks androgynous and has a masculine manner of speech.
• Cold-Blooded Torture: After the Paladins are captured, she forces Lux to whip Greifer and shocks him when he doesn't comply.
• Cruel Mercy: In Volume 4, she planned on sparing Philuffy after forcing her to kill her friends, just to watch her fall into despair and commit suicide.
• Dying Declaration of Hate: As she dies, she calls Listelka a demon.
• Fatal Flaw: Impulsiveness. If she had waited for her eldest sibling to awaken and followed her more pragmatic strategies rather than launching an ill-fated assault on Atismata, she wouldn't have been defeated so early in the series.
• Foil:
  • Combined with Evil Counterpart. She and Lisha are both Warrior Princesses who suffered personal tragedies, but Hayes believes she's automatically entitled to rule over the region and that the powers granted to her by her bloodline make her invincible while Lisha acknowledges that she needs to become worthy of both the throne and her Drag-ride. Also, while Lisha is able to make amends with Lux and see past his bloodline, Hayes is too fixated on revenge against the Old Arcadia Empire to be negotiated with and blames Lux for his predecessors' actions to the very end.
  • Lampshaded by Rosa, who notes that they both became Ax-Crazy psychos in order to cope with feelings of powerlessness and inferiority. Both were saved by someone (King of Vices for Rosa, Listelka for Hayes) who wanted to use them as disposable pawns while promising them glory. Both went through varying degrees of brainwashing, with Rosa being heavily brainwashed while Hayes received light suggestion and had her personality intact. Finally, Rosa pulls a Heel–Face Turn after realizing her master's ideology was just cowardly escapism while Hayes dies unrepentant of her elitist and sadistic lifestyle.
• For the Evulz: She has the goal of restoring the Holy Arcadia Empire, but her actions come off as unnecessarily evil, as shown when she tries to kill everyone in the New Kingdom, tries to drive Phi to suicide, and reenacts the human experiments of the old empire, not to mention awakening Ragnarok, and seizing its core.
• Freudian Excuse: She witnessed most of her family being betrayed and killed by the traitor branch, causing her to become Ax-Crazy and vengeful towards the descendants of the traitor branch and their accomplices. While she always resented her sisters, she really lost her marbles when she nearly died due to Mishis prioritizing Listelka and Aeril's safety first. Deconstructed in that she tries to use her past to justify all of her atrocities while irrationally blaming Lux and the entire kingdom for her troubles, making her less sympathetic instead of more.
• Freudian Excuse Is No Excuse: In Volume 13, Rosa tells Hayes that despite her past of being overthrown, in the end she's just a Royal Brat venting her anger on the entire world and trying to delude herself into thinking she's elite.
• Green-Eyed Monster: She feels that she's fated to be nothing more than a glorified gofer to her sisters, who rank higher than her in the family hierarchy and have more important roles.
• A God Am I: In the climatic battle, she insists that the world should worship her bloodline, if not her personally. After fusing with Sacred Eclipse, she becomes completely drunk on power and insists she was chosen by the gods.
• Hannibal Lecture: She hands these out like candy on Halloween. She even goes on to call the protagonists "stupid," not just for acting in a noble and upright manner, but for failing to know things that they'd have no way of knowing, like Ragnarok's Adaptive Ability, or the full capability to which she can use the Abyss whistle.
• Hate Sink: She was already an unsympathetic character in the first five volumes and anime, whose sole purpose seemed to be to spite the protagonists through any means possible, and every one of her later appearances serves to reinforce that she's motivated primarily by misplaced vengeance, sadism, and envy towards her sisters. It says something when Lux, despite being an All-Loving Hero, considers her beyond salvation.
• Hoist by Her Own Petard:
  • Double subverted in Volume 5. Lux and Lisha use a gravity attack to pull Hayes towards one of her own walls of light/space, which would cause her to get killed by her own Divine Raiment. She manages to dispel a section of the wall in time, but this leaves her open to Lisha's next attack.
  • In Volume 13, Aeril tricks her into using <Astral Line> against the Nigh-Invulnerable Yggdrasil, thus saving Lux getting killed by the Ragnarok. This also dispels the B-blood mode of her Nidhogg, weakening her to the point where Lux can finish her off.
• Hostage Situation: In Volume 14, she use an unmanned Divine Drag-ride, Fernyiges, to capture most of the Paladins and drain their energy. Destroying Fernyiges proves difficult because it constantly uses the Paladins as a shield.
• Humans Are Insects: Every time she refers to the citizens of the Astimata Kingdom, Lux, or Lisesharte, she calls them "fakes" that she intends to exterminate. She also considers anyone who isn't a Lord to be complicit with her usurpers at worst and cattle at best. She also gloats about how the Lords sacrificed their own citizens to create more Elixir for themselves.
• I Have Your Wife: While she doesn't say it out loud, she does employ the spirit of the trope by using an Abyss whistle to force Philuffy to go after Lux. This is one of the few villainous acts in the story with a fair degree of intelligence behind it.
• Inferiority Superiority Complex: Volume 14 shows that the reason she pursues revenge with such zeal is because she feels inferior to her sisters and because she has no great role among the lords. By terrorizing the people of the present, she gets to establish her own role while feeling superior to the people she persecutes.
• Insane Troll Logic: Combined with Royal Brat. She believes that her Holy Arcadia blood means she has the right to conquer and slaughter everyone living in the general area where her empire used to be, and that all present day humans are complicit with her betrayers.
• Insanity Immunity: Unlike Raffi, her personality after fusing with Sacred Eclipse isn't significantly changed, mainly because she was already a psychopath.
• Jerkass: She's very insulting and sadistic to allies and enemies alike, and enjoys pouring salt on their wounds, as shown by how she constantly mocks Philuffy for being part Abyss. Unlike other examples in this series, she doesn't bother to hide this side of her because she feels too superior to everyone else to bother.
• Jerkass Has a Point: She calls out Listelka for blindly trusting someone as suspicious as Fugil, though she's mostly basing this suspicion on his bloodline.
• Kids Are Cruel: While she wasn't as crazy as a child compared to her current state, she still laughed at the prospect of her sisters dying so she could become the top dog in the Holy Arcadia Empire.
• Laughing Mad: There is rarely a scene where she has a speaking role that she doesn't spend laughing like a loon at the glory of her own ego.
• Long Lost Sibling: According to Yoruka, she's Lux's younger sister. (Unless she was referring to Airi.) Subverted when she's revealed to be related to his ancestors instead.
• Mark of the Supernatural: Like Yoruka, Hayes has one violet eye. This is proof she also underwent Baptism surgery.
• Misplaced Retribution: Her relatives who overthrew her side of the family died centuries ago, yet she wants to slaughter everyone in the vicinity of Holy Arcadia empire as retribution, despite how they're a regime change from the original usurpers' government. Regardless if her usurpers were still around, her attacks on innocent citizens and students are still completely unjustified.
• More than Mind Control: Listelka always knew that Hayes had an inferiority complex against her, so she connected Hayes's brain to Avalon to receive voices. Listelka then played on Hayes's desire for power to direct her to fuse with Sacred Eclipse, only taking direct control in order to make Hayes kill herself.
• Mystical White Hair: Her silver hair is a common trait among the members of the Holy Arcadia Empire's royal family.
• Never My Fault: She faults the main characters "for pissing [her] off" as she tries to blow up the kingdom in episode 12. In episode 9, she tries to blame Lux for her manipulating Philuffy against him, and trying to destroy the Astimata kingdom, despite the fact that the two never met before. She was most likely trying to blame Lux for being descended from her usurpers, but fails to see that her grudge is completely unjustified and misplaced considering that he isn't his ancestors and that he's trying to undo their crimes.
• Nice Job Fixing It, Villain:
  • Freeing Yoruka from prison for the sake of tormenting Lux with the threat of assassination because he's rightly opposed to the resurrection of The Arcadia Empire allows Lux to turn her loyalties around and recruit her, and her impressive skills, to his Battle Harem, a possiblity lampshaded by Saniya, repeatedly.
  • Stealing Ragnarok's core to use on her "giant" actually made things easier for the protagonists. Although her rampage undeniably racked up massive numbers of casualties, the situation would have been far more dire if Ragnarok was the antagonist, as Ragnarok has the same level of firepower, if not more, an adaptive ability that allows it to become all but immune to whatever is used against it, bar some really powerful techniques that cause just as much damage to nearby allies, and a powerful healing factor that allows it to basically shrug off just about whatever damage it does take. In addition while the "giant" is slow and cumbersome, Ragnarok is amazingly quick and agile for its size, and can travel underground while the Giant can not. If the protagonists did fight Ragnarok in Cross Feed, it's not likely any of them, or the kingdom as a whole would have survived.
  • What's more, going out in her Drag-ride to attack and torment both Lux and Lisasharte, in person, while the Giant was disabled not only allowed Yoruka to cripple it, by destroying its power core, unopposed, but even if Hayes survived the encounter and fled, the Giant now represents a significant shift in the world's balance of power, in the Atismata Kingdom's favor, especially since Lisasharte and Krulcifer are both experts on the Lost Technology and allied to the Kingdom, through Lux. Though this is subverted when Listelka takes back the Giant.
  • She revealed herself too early in her attempt to destroy Atismata, causing Airi to realize that there are other Holy Arcadia Empire princesses behind the scenes.
  • She uses Deus Ex Machina to teleport Lux away from his classmates, but this allows him to save Soffice, who in turn helps him destroy the Ragnarok.
  • After fusing with Sacred Eclipse, she tests her new powers on Zweigbergk and kills him, but neglects to kill the Triad and Airi.
• Not Quite Dead: She returns in Volume 12 to take control of the Moon and renew her contract with the Dragon Marauders, with the intention of finishing what she started in Volume 5.
• Psycho Supporter: She follows Listelka partially out of their shared elitist beliefs and mostly because she wants to torment anyone remotely connected to her usurpers. Her loyalty ends when she fuses with Sacred Eclipse, due to her belief that she now has the power to rise above her sisters.
• Rape Is a Special Kind of Evil: Combined with Rape by Proxy. After the Paladins are captured, she forced the females to strip in preparation for forcing them to have sex with Lux. Fortunately, Aeril steps in before this plan can go anywhere.
• Really 700 Years Old: She's not actually in Lux's generation of Arcadia royals. A document that Airi found in Volume 5's epilogue reveals that she's actually from the Holy Arcadia Empire that preceded the Old Empire.
• Revenge Before Reason: Combined with Stupid Evil. Fugil and Mishis call her out on waging war on Atismata after losing Yggdrasil, one of their best Ragnaroks. During the war on Atismata, she actually lampshades that totally leveling the city and killing the most of its inhabitants would make it harder for her to fully establish her rule in the region, but decides to attempt it anyways out of spite towards the protagonists.
• Royally Screwed Up: If Hayes can be believed, her bloodline's the actual heirs of the Arcadia Empire, not Lux's. Fugil actually addresses her as "your majesty" so she's clearly of royal blood somewhere, and the Loyal Phlebotinum Lux, Krulcifer, and Lisesharte found earlier does consider her a higher-priority than Krulcifer, so her claims clearly have merit.
• Slasher Smile: She has one almost all the time due to her Ax-Crazy demeanor, to the point where it's slightly hard to tell whether she's grinning in triumph or having a Villainous Breakdown from her expression alone.
• The Sociopath: A low-functioning example, arrogantly convinced of her own invincibility to the point where she doesn't even try to hide what an horrible person she is. Unlike the other examples listed on this page, her impulse control is practically non-existent, causing her to become enraged at minor setbacks and causing her to make poor long-term decisions.
• Space Master: Nidhogg's Divine Raiment, <Astral Line>, can create Sword Beams that can cut space itself, causing walls of light to appear.
• The Starscream: After fusing with Sacred Eclipse, she turns on Listelka and attempts to clear the third trial of Avalon by herself.
• Superpowered Evil Side:
  • Hayes states that she has a different version of Baptism from Yoruka, which explains why she has Tainted Veins when piloting Nidhogg. According to Listelka, this specific version of Baptism allows her to control any of the Ruins' Automata.
  • In Volume 13, she puts a piece of Yggdrasil into her Drag-ride to give it a B-blood form.
• Sword Beam: Her Drag-Ride uses a truly massive one that stretches across the city, just to show that she could easily kill all the citizens even without her giant.
• Tainted Veins: While piloting her Drag-Ride in the climax, she starts getting jagged lines on her face.
• Taking You with Me: After Listelka forces her to kill herself, Hayes attempts to kill everyone in the surrounding with Yggdrasil's branches, only to be easily cut down by Fugil.
• 13 Is Unlucky: She is from the thirteenth generation of the Holy Arcadia imperial family.
• Uncertain Doom: The anime doesn't show if she lives, escapes, or gets captured after her defeat. The light novel states that her body was never found.
• Ungrateful Bitch: Despite being saved by Fugil in Volume 4, she disparages him when he wisely tries to warn her from starting another battle she can't win.
• Unskilled, but Strong: A subtle example, but she's mostly evenly matched with Lisha in combat despite having a stronger Drag-ride, a One-Hit Kill space-warping Divine Raiment, and Baptism to enhance her dexterity. Lisha notes that Hayes doesn't know how to use <Astral Line> efficiently and compensate for her limited number of maintainable light walls.
• Unwitting Pawn: She believed that Avalon itself was telling her that she was qualified to complete the third trial simply by being fused with Sacred Eclipse. This turns out to be a message that Listelka implanted in her, all so she could manipulate Hayes and therefore control Sacred Eclipse by proxy.
• Villainous Breakdown: Gets a short but effective one when Yoruka betrays her.
• Villainous Princess: She is the worst of the lot, an Ax-Crazy maniac and Royal Brat who sparks a war with Atismata and kills many innocents, intending to make the world worship her.
• White Hair, Black Heart: She has silver hair like Lux, but she's Ax-Crazy and a Manipulative Bitch.
• Xanatos Gambit: Hayes using Philuffy againts Lux reeks of this. Either Lux does what she wants and helps Hayes deal with Ragnarok, on the slim chance that Hayes will free Philuffy, Philuffy eventually goes on to kill Lux, or Lux is forced to Mercy Kill Philuffy thus not only crushing him with guilt, but possibly alienating him from the Altismata Kingdom. In any of the above, Hayes wins. She couldn't take into account that Airi would be adept enough with the Abyss flute that she could "overwrite" the commands on Philuffy's abyss side and set her free.
• You Are What You Hate: Despite hating the Old Empire, she's just as sadistic, treacherous, and willing to experiment on humans as them, if not more so. The only real difference is that she doesn't care for their androcracy.
• Your Days Are Numbered: Due to her defeat in Volume 5, she only has about 10 days to live starting from the end of Volume 12. She intends to cause as much pain and misery as she can to Lux and the new kingdom before she kicks the bucket.

Listelka Rei Arshalia

Listelka Rei Arshalia

An ally of Fugil's who awakens in Volume 6. She is the first princess of the Holy Arcadia Empire.

---

• Asshole Victim: Fugil stabs her right before she can clear the third trial of Avalon. While this is incredibly cruel because of how much she trusted him, she lost all sympathy when she: demanded the heads of all the world leaders, declared war on the rest of the world, started False Flag Operations all over the world, and callously treated her sisters as disposable pawns.
• Big Bad Wannabe: She's the leader of the Lords and a ruthless schemer to boot, who successfully manipulates the entire world into helping her reach Avalon, kills most of the alliance army, predicts her sisters' disloyalty, and manages to reach the third trial of Avalon before everyone else. Despite that, she fails to apply the same caution to her "hero," Fugil, causing her to be killed by him at the end of Volume 14.
• Bitch in Sheep's Clothing:
  • Combined with Faux Affably Evil. She seems graceful and polite when opening negotiations with every country, but the Seven Dragon Paladins know that she's still scheming against them and withholding important information about Sacred Eclipse. That said, she seems to be genuinely Affably Evil towards Fugil and trusts him completely.
  • She pretends to care about her sisters, but in reality sees them as disposable pawns. After Aeril outlives her usefulness, Listelka plans on turning her into a vegetable to harvest her genes. She also shows sympathy towards Hayes for having little time to live, but was really planning on sacrificing her for the Avalon trials all along.
• Death Glare: She gives Hayes a look of killing intent for insulting Fugil.
• False Flag Operation: She sends several humanoid abysses into the other countries to transform into rioters and soldiers fighting each other, causing panic among the citizens.
• I Surrender, Suckers: She pretends to surrender after the revived Ragnaroks are defeated while secretly intending to blow them all up to kill the Paladins. Magialca isn't fooled and immediately destroys the Ragnaroks and most of the Heaven Palace.
• Lady and Knight: She thinks she and Fugil fit this trope because he saved her in the past, but Lux and Aeril think her trust in Fugil as her "hero" is misplaced.
• Loving a Shadow: Despite falling in love with Fugil, she never realized he had completely different ideals from her.
• Meaningful Rename: Her last name used to be Arcadia, but got changed to Arshalia, which is the same as the first name of the first Arcadia princess. This is because of her status as the Shrine Maiden of Oracle, meaning she inherited the role of her ancestor.
• Mystical White Hair: Her white hair is one of the shared features of the royal family of the Holy Arcadia Empire.
• Never My Fault: She refuses to admit that the main reason the Holy Arcadia Empire fell was because their tyranny earned the ire of all their subjects, allowing the branch family to turn the whole world against them in a coup. When Fugil spells out why she's unworthy to rule the world, Listelka can't comprehend his words, since she can't understand why it's wrong for her to put her ambitions above the masses.
• Non-Action Big Bad: Despite being the leader of the Lords and having Baptism applied to her body, she's never seen in combat. Subverted in that she's not the real Big Bad.
• Pragmatic Villainy: Despite gaining control of the Gigas that Hayes left behind, she decides to retreat with the mobile Ruin rather than go on a rampage, since this will allow her to negotiate with the Kingdom of Atismata.
• Really 700 Years Old: Like Hayes, she's a remnant of the Holy Arcadia Empire and is the first princess to boot.
• Rewarded as a Traitor Deserves: She tries to inflict this on Singlen and Magialca when they agree to become her servants, under the rationale that people willing to betray their countries will end up betraying her. However, this was a gambit on their part to make Listelka less suspicious of Lux in comparison, causing Listelka to allow Lux to accompany Aeril.
• The Sociopath: She is just as cruel, selfish and malicious as Hayes, she's just better at presenting herself as a good person.
• Take Over the World: Unsurprisingly, she is mainly seeking Avalon to rule the world rather than just defeat Sacred Eclipse.
• 13 Is Unlucky: She is from the thirteenth generation of the Holy Arcadia imperial family.
• Unwitting Pawn: Fugil only saved her and her sisters in order to use them to open Avalon.
• Villain Has a Point: She points out that Lisha is too dependent on Queen Raffi when it comes to diplomatic and political activities, which is unbecoming of a princess.
• Villainous Princess: She is the nominal leader of the Lords' Faction who masterminds the plot to Take Over the World.
• Walking Spoiler: The existence of her and her sisters raises a lot of questions about Fugil as well as the past of the Arcadia family.
• White Hair, Black Heart: She's as much of a cruel villain as her younger sister Hayes and they share the same silver hair color.
• You Are a Credit to Your Race: She believes Fugil is the only good member of the family's traitor branch, though this is based on her skewed and self-centered morality that anyone who is loyal to her is good and everyone else is evil.

Aeril Vi Arcadia

Aeril Vi Arcadia

Drag-ride: Zahhak

The second princess of the Holy Arcadia Empire.

---

• Apologetic Attacker: She apologizes to Lux and Greifer as she knocks them out and kidnaps them.
• The Atoner: She allows the alliance to take her prisoner as atonement for betraying them and unwittingly wiping out most of their forces.
• Badass in Distress: After Fugil defeats the Paladins, she's kidnapped and forced to help Raffi secure her rule. Fortunately, Lux and the Kilzrake family find her in Garden and rescue her. Afterwards, everyone not in on Raffi's plans thinks she's been kidnapped by the Kilzrake family.
• Becoming the Mask: Her time undercover caused her to realize that the rest of humanity aren't just meant to serve the Lords.
• Even Evil Has Standards: Downplayed on the evil part due to being the Lords' Token Good Teammate.
  • She notices that Fugil doesn't consider humans as living things and is creeped out by his Lack of Empathy, despite being his ally.
  • She's disgusted with Hayes for trying to force Lux to torture the other Paladins.
• Foreshadowing: Her perception manipulation ability comes from Avalon. Ouroboros's <Endless> turns out to be the same basic function, but on a larger scale.
• Generation Xerox: Despite not inheriting Arshalia Rei Arcadia's name, Aeril is similar in that she's the only good person of her generation of imperial princesses and falls in love with someone from the traitor branch of the family.
• Mark of the Supernatural: Like other people with Baptism applied to their body, Aeril has heterochromia. In her case, she has a light grey right eye and a light green left eye.
• Master of Illusion: Due to a special Baptism applied to her body, she can affect the perception of others, allowing her to maintain her false identity as Coral and easily knock out the Paladins.
• My God, What Have I Done?: She feels so much guilt over unwittingly helping Listelka kill most of the world alliance army that she tries to goad Lux into abandoning her. Fortunately, Lux convinces her to fight alongside him and atone.
• Mystical White Hair: Like other members of the Holy Arcadia Empire's royal family, Aeril has silver hair.
• Out-Gambitted: After learning that her side of the family was Evil All Along, she tries to secretly work against Listelka. Unfortunately, her sister saw her betrayal coming and fed her false information.
• Parental Substitute: Aeril and Soffice release the descendants of the Arcadias and Xfers from stasis and raise them.
• This Is Unforgivable!: Despite disagreeing with her sisters and defecting from them, she can't forgive Fugil for killing them.
• Unwitting Pawn: Listelka lied to her about the true effects of activating Avalon, causing Aeril to unwittingly give Listelka control of all the resurrected Ragnaroks. She also had no idea that Listelka set Lux's Wedge so that if Aeril removes it, the Wedge will kill them both.
• Villainous Princess: She downplays it heavily as she is the Token Good Teammate of the Lords' Faction, but she still aids them in their mass-murdering plans, at least until she learns their real intentions and does a Heel–Face Turn.
• Weapon Specialization: Zahhak's main weapon is a whip.
• White Sheep: She's the only member of the Holy Arcadia family with a conscience, as shown by the revelation that most of them were Mirroring Factions tp the Old Arcadia branch.
• Will They or Won't They?: At the end of the series, Aeril chooses not to marry Lux yet, since he's going to be burdened with being the acting king of Atismata. She states she might consider it after Lux has fewer responsibilities, but Soffice tells her this could lead to a pattern of failure.

Mishis V Xfer

Mishis V Xfer

Drag-ride: Azi-Dahaka

---

• Adapted Out: Despite appearing as early as Volume 3 of the light novel series, she doesn't show up in the anime.
• Asshole Victim: Downplayed when Fugil kills her, as she was shown to have some standards despite her loyalty to the wrong side.
• Crippling Overspecialization: Downplayed. She's an expert at defeating Drag-ride users, but scores a draw against Celestia when the latter sheds her armor and fights more like a human.
• Even Evil Has Standards:
  • Like Aeril, she is disturbed by Fugil's obvious disregard for human life and also finds him untrustworthy.
  • She's not pleased with Listelka's willingness to kill Aeril for plotting against her and secretly hopes that such an event never happens.
• My Master, Right or Wrong: She never voices any of her thoughts in her Even Evil Has Standards entry because of her loyalty to Listelka.
• Offscreen Moment of Awesome: She defeats Sacred Eclipse by herself, a feat the protagonists never pulled off alone.
• Red Baron: She's known as the "Anti Drag-knight" due to her skill in using <Avesta> to steal Divine Raiments.
• Strong and Skilled: Unlike Barzeride, she knows how to use Azi-Dahaka to its full potential, allowing her to defeat Celestia and Philuffy at the same time. She also studied the abilities of every Divine Drag-ride except for Ouroboros, allowing her to come up withs strategies for almost any opponent.
• Worf Had the Flu: Downplayed. She's tired from her battle with Lux's harem, but when she fights Fugil, she makes sure to overdose on Elixir first in order to recover her strength. She loses and gets beheaded when she's caught off guard by Fugil's Zero One armament.

Arshalia Rei Arcadia

A princess from the distant past of the Holy Arcadia Empire, who also has Xfer blood. Not to be confused with the Automaton of the same name.

---

• The Ace: She's the greatest engineer of her generation, as shown by how she made new developments in Ruin technology in a few years.
• Artificial Intelligence: Lux and Aeril find a disc that contains an AI based on her personality.
• Cruel and Unusual Death: When Fugil wakes up from his coma and looks for her, he finds that she was brutally mutilated and tortured to death by the traitor clan.
• Cynicism Catalyst: According to Fugil, she was betrayed by the people she tried to save, which caused him to become misanthropic.
• Engineered Heroics: When she realizes that the entire world fears her and Fugil for their power, she intentionally programs Sacred Eclipse to attack anyone who is hostile so that Fugil can defeat it and gain the population's trust, though he's unaware of this.
• Godhood Seeker: She intended to use mass mind manipulation to erase everyone's hatred and become a "Goddess of Salvation." Her AI later admits she was conceited to think this way.
• Heel–Face Turn: Her AI admits that she succumbed to despair and hatred just like the traitor clan and Holy Arcadia Empire, leading to her engineering a plan for Fugil to defeat a rampaging Sacred Eclipse. She also regrets that her actions resulted in Fugil taking on a hopeless mission to save the world. She then gives the protagonists advice on how to defeat Ouroboros in the hopes they can put an end to Fugil's mission.
• Unwitting Instigator of Doom: She didn't intend for Sacred Eclipse to feed on humans, but other people stole Sacred Eclipse and corrupted it into having a killer instinct. Subverted when it turns out she set Sacred Eclipse to go berserk so that Fugil can defeat it in front of the world, though she intended to program it correctly after the initial attack. However, she gets killed before Fugil wakes up and never reprograms Sacred Eclipse to its original settings.
• Uptown Girl: She's a princess who is the love interest of Fugil, a commoner in their era.
• Villainous Princess: She was less bad than Listelka and Hayes in that she wasn't a power-hungry maniac, but she was a Well-Intentioned Extremist who tried to manipulate everyone's memories to make everyone forget their hatred towards the nobility, and let loose the dangerous Sacred Eclipse so Fugil could defeat it and look like a hero, restoring the family's reputation.
• Well-Intentioned Extremist: She attempted to get the ruling class and commoners of her time to make peace through normal means, but couldn't erase their hatred and greed. She eventually resorts to creating Ouroboros and its <Endless> Divine Raiment in order to make everyone forget their hatred via memory manipulation. She also created Sacred Eclipse to help find and save the less fortunate, but found that Sacred Eclipse would always turn on her and Fugil because both the rebels and the Holy Arcadia Empire resent them for their power. She then programs Sacred Eclipse to attack anyone with hostile feelings without telling Fugil so that he'll defeat the Ragnarok and appear as a hero to everyone.
• White Sheep: Despite the Well-Intentioned Extremist entry above, she was the only royal of her generation who wanted to use the Ruins' technology for world peace and also looked past her family's prejudice against the clan of traitors.
