God
In General
The God and creator of Earth, who, in actuality, is two separate beings engaged in an eons long game to see whose vison the world will shape itself into.
- Ambiguous Gender: Both are referred to with gender neutral pronouns and it's ambiguous as to whether they even have a concrete gender at all.
- Ambiguous Situation: While its made clear Sun births the UMA and Luna created the Artifacts, its unclear which of them is responsible for Negators.
- Cosmic Chess Game: The entire series is driven by their game to see whose version of Earth is better, with Luna betting on people and gifting them Artifacts and Sun betting on the Rules and birthing the UMA.
- Jerkass Gods: Both of them fall into this to a degree. Sun is obviously this, being the series' Big Bad who is deliberately trying to terrorize humanity, while Luna is A Lighter Shade of Black who is supporting humanity, but is still shown to be dismissive and uncaring about their suffering and deaths,
- Kick the Dog: As mentioned below, whichever god deals out the negations often does so at times it would spell disaster for the new Negator.
- No Name Given: "The god," "the creator," or just "God" were the names used to refer to the being the Union was fighting through the first part of the story, with even the series' first official character poll referring the being was "God?" instead of a proper name. This is because "God" is actually two beings, Sun and Luna, rather then being single entity.
- Solar and Lunar: One is the sun, the other is the moon, both of which were notably the only other celestial bodies in the universe before Galaxy's addition.
- Super-Empowering: One of them decides who gets a Negator power when its previous user dies. They usually pick someone in a scenario where receiving a power at that exact moment would be disastrous for them. It is later revealed the choice of the next Negator is influenced by the previous ones, although it doesn't change the fact they still choose the worst possible timing for them to get said powers.
Sun
Sun
Click to see their physical form
One half of the God responsible for creating the world, the sun itself who has sided with the rules and given birth to UMA to terrorize humanity
- Big Bad: The series main antagonist, responsible for creating the UMAs and constantly throwing the Earth into world-ending scenarios. The Union's main goal is to defeat it and free themselves from his.
- The Computer Is a Cheating Bastard: As the non-player character of the game the "game" negators play against it, he has clearly rigged the game in his favor. Fuuko, for example, points out that the creation of an UMA not always creates a negator, creating an imbalance in the UMA's favors and making many of them have no direct weakness, and matches like UMA Move and the Unmove negator are rare.
- Demonic Possession: While it typically remains an outside force, it's capable of possessing and manipulating UMAs directly, such as with Spring in his titular arc.
- Evil Is Bigger: Compared to every other UMA, Sun is absolutely massive. Simply standing up causes considerable damage to its surroundings and its feet sink into the earth.
- Evil Is Burning Hot: Being the very concept of a sun itself, even being around it is dangerous because of the heat its body gives off.
- God Is Evil: Is the creator of Earth, but is also constantly putting it in danger by adding new rules to it via UMA, whom it explicitly tells to use their rules to make humans suffer. It's destroyed countless Earths from previous loops as well, yet continues to recreate the world just to try and destroy it again. Then there's the fact it forces Spring into a more aggressive form because of the UMA purposely not using its full strength to torment humans. Not to mention it's heavily implied Sun is purposely ensuring humanity will always be on the losing end, such as making Akira Unknown to ensure he couldn't reveal anything he learned from touching G-Liner.
- Invincible Villain: Everything the Union and Under throws at Sun does no real damage and can only buy time for Fuuko to use the Ark to travel to the next loop.
- The Power of the Sun: God turns out to be Sun, making it the sun and the concept of a sun itself.
Luna
Luna
The other half of the God responsible for creating the world, the moon who has sided with humanity and blessed them with artifacts.
- Bargain with Heaven: Enacts one of these with Juiz. In exchange for Juiz transferring her 'points' to Andy and Fuuko (resulting in her no longer being able to loop), Luna sends the pair to the future when the quest rewards are given to save Fuuko's life.
- Big Good: While not entirely benevolent, it's on humanity's side and gives as much support to them as its allowed. This is further zig-zagged during the fight against Sun as while they claim to bet on people in their fight, but does not appear to be attached to them in any way even as they die. Yes, they are more benevolent than a being who actively wants to snuff out humanity, but certainly not good. Chapter 198 adds further ambiguity with the reveal that UMA Soul, the first and only rule that actually benefits humanity, is the only UMA that was created by Luna rather than Sun. When Soul questions his creator about it, their only response is to claim it's simply more amusing that way, although Soul notes that isn't the full truth.
- Deal with the Devil: While agreeing to Juiz's request to send Andy and Fuuko to the future, Juiz mentions that the deal works in their favor. Being that both Ruin and Luna enact God's will, the deal only came about due to Juiz having her hand forced by them.
- Emissary from the Divine: Keeps Juiz abreast of God's thoughts after Andy begins wantonly killing UMA despite no quests being given. It even attempts to have Juiz stop him and after she informs it that she doesn't have any control over him after Ruin's attempt on Fuuko's life, it tells Juiz about God enacting 'regulations' after which UMA Seal is summoned to capture Andy.
- Time Master: Is first shown after Juiz bargains with it to send Andy and Fuuko to the future to save her life. This is not done for free as Juiz gives up the ability to loop altogether in order to strike the deal.
Regulators
Specialized enforcers of God's will. Ruin
'Ruin'
Power: Unruin
A mysterious Negator who appears to hold the creator of the world in absolute reverence.
- Bloody Murder: Having bonded with UMA Blood, he's able to utilize blood attacks to a greater extent than even Andy. While not named, many of his attacks are visually similar to both Andy and Victor's.
- Establishing Character Moment: He appears out of literally nowhere just as Andy and Fuuko are reaffirming their desire to fall in love together and finally get Fuuko's Unluck to end his immortal existence, fatally stabbing Fuuko in the heart with no warning and making it clear that he won't tolerate her existence, mocking Andy's anguish and making it clear that he wants nothing less than to deny them both their happiness together before leaving. Even after the Round Table manages to figure out a way to save Fuuko's soul to potentially resurrect her, he stages a massacre of humans to get UMA Ghost's attention in bringing Fuuko's soul to him, asking it to devour every trace of her, making it clear that he won't settle for anything less than her absolute erasure. This sets him up as an effective Knight of Cerebus and devoted antagonist to both Andy and Fuuko on a personal level.
- Evil Cannot Comprehend Good: Words and concepts like family and friends, as well as the grief their deaths cause, mean nothing to him. At best they're just tools for him to use to his advantage, like when he caused Nico to have a Face–Heel Turn by showing him the ghost of his lover through UMA Ghost.
- Evil Counterpart: To Andy. Andy is empathetic and caring towards others and dislikes seeing people suffer, especially after meeting Fuuko. Ruin is a mass murderer who is fanatically devoted to 'God' and doesn't seem to care about who he kills.
- Fridge Logic: In-universe example. Billy wonders how Ruin could get the drop on Fuuko and how someone like Juiz who went through many loops before didn’t know about his existence until now. Billy figures out it’s because Unruin is an inferior version of Undead that can’t save the user when the world ends and loops back to the beginning, hence why Ruin never appeared before until now.
- Hero Killer: His first appearance is attempting this on Fuuko. He very nearly succeeds too, with Fuuko's soul being put into limbo.
- Irony: He has a vampiric weakness to sunlight, burning in it, though his healing factor is powerful enough that this won't kill him, and at worst causes his upper layer of skin to repeatedly burn away and restore itself. He's fanatically devoted to 'God', who turns out to literally be the concept of the sun itself. His second appearance after fatally stabbing Fuuko has him admiring the sun underneath a parasol made by UMA Blood, before asking it to dispel his protection, stating that there must be some meaning for him being in this much pain from sunlight under the master rules imposed by God.
- It's Personal: Though he's usually depicted as being perpetually cheery, his actions and words make it clear that he holds a personal dislike of Fuuko for unspecified reasons, apparently relating to how she's made Andy a better person from their time together, and whilst he overall desires to see God's will done, he's personally devoted to erasing Fuuko's existence however he can. Although he hates to admit it, Billy has also triggered this within him by dismissing his abilities and importance to God. Unfortunately for him, this means that Billy gets access to Unruin.
- Scars Are Forever: Despite having a Healing Factor comparable to Andy's own, for some reason his left eye has a noticeable impact scar around it that never heals no matter how damaged his face becomes.
- Serial Killer: In spades. Chapter 99 reveals he's killed multiple groups of people, using an UMA to turn them into laughing zombies before they die.
- Token Heroic Orc: Inverted. He's the sole Negator to be genuinely on 'God's' side and be genuinely evil, in start contrast to the Union and Under who are, at their worst, morally unscrupulous.
- Walking Spoiler: His presence isn't even hinted at until the end of the UMA Spring arc and his first actions kick off the plot of the next one.
Seal
Seal
An UMA created by God to regulate Andy and stop him from killing UMA.
- And I Must Scream: Its goal is to seal Andy for an eternity since it cannot kill him.
- Bandaged Face: Its face and body is covered in wrappings which it uses to seal others.
- Berserk Button: It doesn’t like it when Andy says it’s no different from other UMA and demands he apologize.
- Impaled with Extreme Prejudice: It's last seen in the 100th loop having been impaled by Feng's Zuishin Tekkan Rod to ensure Seal could not try to further interfere with the Union's efforts to allow Fuuko to loop.
- Power Copying: Seal can use the powers of any UMA or Negator that is currently sealed within it.
- Supernatural Sealing: Its entire purpose upon its creation is to seal the Undead Negator and other UMA.
- The Worf Effect: It almost gets the better of Andy and ends up fatally wounding Top and Haruka to deactivate Unbreakable, only for it to have been defeated by Feng off-panel.
The Superior Rules
The Master Rules are special rules chosen after Ragnarøk occurs that become permanent in all future loops. In general, they hold greater power then the average UMA, with the top ten of which being known as the "Superior Rules" and occupying their own Roundtable located in the sun itself. In General
The tablet that shows the numbers of the master rules
Click here to see the top 10 Master Rules
- Ancient Evil: For the earlier master rules, especially the the Superior Rules who’ve been around ever since the loop’s earliest stages, which started approximately 450+ billion years ago.
- Evil Counterpart: The first ten are collectively this to the Union, being strong, human-looking individuals who gather a round table. The Master Rules' table is a color-inverted version of the Union's to emphasize this. Several of them take this even further by being the very rules several of the Negators negate, with Death acting as one to Andy's "Undead", Change acting as one to Gina's "Unchange", Luck acting as one to Fuuko's "Unluck", and Justice acting as one to Juiz/Julia's "Unjustice".
- Humans Are Insects: With the exception of Soul, they collectively see humanity as beneath them, and arrogantly believe their victory against humanity is assured. This is in spite of the fact that Juiz has managed to kill most of them across the 100 Loops, with their choosing to blame it on her use of "Unjustice" more than anything. Soul points out that this is their Fatal Flaw, their inability to recognize humanity's potential to use the Rules of "Soul", "Death", and "Change" to their advantage, hence their incredulity when Fuuko, Top, Haruka, and Julia succeed in killing Beast, and that if they continue to act as if humanity is truly beneath them, the Master Rules will lose to the Negators. The mere notion of such is enough to send Luck, War, Sick, and Change into a rage and results in them trying to attack Soul, only stopping when Soul reminds them that none of them could beat him even if they tried.
- I Gave My Word: If they offer a reward for completing a goal, they must give said reward regardless of their feelings on it if the goal is completed.
- Logical Weakness: Thanks to them all having views of humanity similar to Sun, Juiz’s Unjustice is exceptionally more effective against the top ten Master Rules, forcing them to act in opposition to their views of justice and allowing Juiz to defeat a majority of them without using Soul Power.
- Orcus on His Throne: Justified. The Master Rules are powerful UMA whose weakest member gave the Union a difficult fight, but as Fuuko discovers, they can't actually leave the Master Room or harm Fuuko outside a quest because Andy has been sealing them away. It's only because of Andy weakening after holding them back for millions of years that Sick was even able to appear in a quest.
- The Pretty Guys Are Stronger: Unlike other UMA, the Superior Rules, the most powerful of all the UMA, are all human in appearance. It's implied that becoming a Master Rule bestows this upon them, with lesser UMAs still having an inhuman appearance. This seems to be another of God's cruel ironic fates, as some UMAs like Spring are shown to be attached to humanity, but rejected because of their monstrous appearance, yet the UMAs that could fit in amongst them with a bit of disguising are the ones most dedicated to enforcing Gods will of wiping humanity out.
- Soul Power: All of them derive their powers via soul manipulation in some form or another, something Fuuko comes to realize after figuring out that the first rule added was "Soul". For example, Beast acts as The Beast Master by attaching Soul Chains to beasts and making them subservient to him, and can attain the powers of beasts or even Negators via Soul Eating.
- Standard Evil Organisation Squad: Seems to be shaping up as this for the final stretches of the 101st loop, at least for the first ten, since they are distinguished by Apocalypse as being the strongest of the 100 chosen so far. Sick even has an X on his chest denoting his position as the tenth master rule.
- Not So Invincible After All: The top ten Master Rules are shown as being utterly unbeatable by humanity until one learns how to use the Soul Power aspect of their Negator powers. Fuuko learning how to do so and teaching Haruka and Top to do it as well allow the three to defeat and kill Beast.
Soul
UMA Soul
The First Master Rule
Seat I of the Master Rule Roundtable, the first rule added that represents the concepts of souls and their energy.
- Affably Evil: He's generally respectful and cordial despite being the top master rule. While he does try and intimidate Fuuko during their first meeting, he laughs when it's clear it didn't work and happily answers her question about Andy's whereabouts to reward her boldness after the fact.
- Energy Weapon: He summons a blade made of his own soul when fighting Andy in The Master Room.
- Humans Are Special: Something that separates him from his fellow Master Rules is that he acknowledges just how special humanity is, how they've managed to utilize the Rules of "Soul", "Death", and "Change" to achieve unimaginable feats, and at their current rate of growth are more than likely going to win against them. This is contrasted by the rest of the Master Rules viewing humanity as inferior, which Soul points out is the reason Juiz was able to beat them in the prior 100 Loops, and the reason why Beast was killed by Fuuko, Top, Haruka, and Julia, that they refused to acknowledge the potential humanity holds, and were more fit to blame their prior loses on Juiz's use of "Unjustice". Justified as the majority of the Master Rules were created by Sun, and therefore share his disdain for humanity, while Soul was created by Luna, and shares her appreciation of humanity even if it's his job to lead the Master Rules in ensuring their downfall.
- No-Sell: Andy's soul chains are able to tie all of the other Superior Rules with ease, but he can simply knock them away without worry due to his rule.
- Punch-Clock Villain: He makes clear he doesn't have any sadistic pleasure in torturing humanity, nor does he have any devotion to enforcing Sun's orders of him. He just sees it as doing his job as leader of the Master Rules. He even takes on the role of a Combat Commentator for Fuuko, Haruka, and Top's battle with Beast, genuinely complimenting their ingenuity and figuring out how to use Soul Power, his only response to Beast's death being that they'll meet again in the end if the Master Rules ultimately win.
- Soul Power: He represents the rule of souls and their energy to the world, allowing to contend even with Andy's otherwise unbeatable soul-based techniques with little effort. As Fuuko realizes, this is the base of most other UMA's abilities and even the nature of the Negator powers.
- Uniformity Exception: He's the only Master Rule that was not created by Sun; rather, he was created by Luna. Fittingly, while all other Rules that came after him were meant to restrict or punish humanity, "Soul" is the only Rule that solely benefits humanity, which Soul confirms when he questions Luna on why she made him first and gave humanity "potential". He similarly is the only one who possesses Villain Respect for humanity, noting that Humans Are Special, while the other Master Rules all despise humanity.
- Villain Respect: Towards both Fuuko and Andy. He finds Fuuko amusing due to being much bolder and crazier than Juiz was in the past, and openly calls Andy the "strongest Negator" in amazement for his incredible use of soul-based techniques to hold all the Superior Rules off. He later is impressed by Fuuko, Haruka, and Top turning the battle against Beast thanks to a new understanding of souls.
- World's Strongest Man: With the exception of God, Soul is the strongest UMA there is. Even if the other nine Master Rules ganged up on him, Soul implies he would easily be the victor. So far, only Andy has given him a challenge.
Death
UMA Death
The Second Master Rule
Seat II of the Master Rule Roundtable, an UMA that represents the concept of death.
- The Grim Reaper: She's the embodiment of the rule of death.
- Prayer Pose: She's constantly in one of these, even when being chained up by Andy's soul chains.
- Sinister Minister: She's a nun-themed UMA who works to uphold God's authority as a member of the Master Rule Roundtable.
- Smells of Death: According to Change, Death fittingly reeks of blood and guts, something that she is quite insecure about.
- Statuesque Stunner: Death takes on the appearance of a young woman with an ethereal beauty to her, and also stands taller than all the other Superior Rules besides War.
Change
UMA Change
The Third Master Rule
"Aha... I see. So you're my vessel, are you? In that case, let me change you into a more attractive women."
Seat III of the Master Rule Roundtable, an UMA that represents the concept of change.
- Berserk Button: Andy is one to her thanks to him having forced the Master Rules to stay on the Sun for millions of years and him not changing at all in the meantime. Andy constantly flashing his naked body, especially a certain part between his legs, also adds to Change’s hatred of the man.
- Hair-Trigger Temper: Change is incredibly quick to explosive, vein-pulsing anger, usually over the Negators defying her rule or achieving any sort of victory over the Master Rules.
- Improbable Hairstyle: Her hair is styled into two extremely long pigtails that resemble strands of DNA, likely to represent her ability to alter things on a molecular level.
- Ms. Fanservice: Change takes on the form of a beautiful woman in a Little Black Dress that shows off her breasts and long legs.
- Transmutation: As Gina's opposite, her powers are fittingly based in this. Where Gina can solidify objects in place, Change can shift an object's state of matter on a whim, such as when she began liquifying the Union's space suits while they were visiting Andy on the sun. She also implies she can affect living beings as well by her comments about changing Gina's form before getting interrupted by Andy.
Luck
UMA Luck
The Fourth Master Rule
Seat IV of the Master Rule Roundtable, an UMA that represents the concept of luck.
- Four Is Death: They are the Fourth Master Rule and is the UMA representing the concept of luck, falling under this as they are an antagonist and one of the most powerful Superior Rules.
- In-Series Nickname: UMA Death calls them "Lucky", which indirectly confirmed them as UMA Luck in their first appearance.
- Lady Luck: They're the physical embodiment of the rule of luck, making them this in the Undead Unluck world. Their exact gender is unknown at the moment, however.
- Pointless Band-Aid: Has one on their left check.
- Unusual Halo: They have a floating halo above their head that fittingly resembles a wheel of fortune.
Justice
UMA Justice
The Fifth Master Rule
Seat V of the Master Rule Roundtable, an UMA that represents the concept of justice.
- Knight in Shining Armor: Fittingly, their design invokes this concept. They don a full suit of knight armor and carry a claymore, reflecting their rule as knights are seen as symbols of justice and heroism.
- The Quiet One: Out of the Master Rules, they notably don't talk much and the only instance they have spoken so far is a moment where all of the Master Rules agree to try leaving the Master Room.
War
UMA War
The Sixth Master Rule
Seat VI of the Master Rule Roundtable, and UMA that represents the concept of war and conflict
- The Big Guy: War is notably larger than all the other Superior Rules in both height and width.
- Cigar Chomper: He is always seen smoking a large cigar.
- Spontaneous Weapon Creation: He can summon weapons of war by calling for them over a walkie-talkie, such as summoning a tank to blast Andy out of the Master Room.
- Two-Faced: The right side of his face looks like a normal, gruff man's face, while the other half is skeletal with smoke from his cigar pouring out of the open sockets.
- War God: He's the physical embodiment of the rule of war, making him this for the Undead Unluck world,
The Seventh Seat
The Seventh Seat
The Seventh Master Rule
Seat VII of the Master Rule Roundtable.
- Evil Old Folks: He's a Superior Rule with the appearance of an older gentlemen, with both Soul and War referring to him as "old man" despite both being older rules.
- Time Master: While not said, it's implied he is the Master Rule "Time", as he appears to have a limited control on time in some capacity, allowing him to slow down Andy's regeneration at one point, and he announces the exact time of Beast's death when his chair disappears.
Language
UMA Language
The Eighth Master Rule
Click to see her third phase
The VIII seat of the Master Rule Roundtable, an UMA that represents the concept of Language.
- Bookworm: She has her nose buried in a book non-stop, no matter the circumstances. She notably only looks away from her precious literature when she finally finds Nico after returning to Earth.
- Early-Bird Cameo: Her name was dropped all the way back in Chapter 10 of the manga, as neutralizing her was one of the first quests revealed in the series, though the actual event happened offscreen by Nico with her actual appearance never shown. It wouldn't be for over a hundred and seventy chapters later that she would make a physical appearance as a Master Rule UMA.
- Enfant Terrible: She's one of the 10 Superior Rules, but resembles a prepubescent, bratty girl in her Phase 2 form. Behind her cute face, she hides a vicious grudge against Nico, flashing multiple slasher smiles at him when they finally meet again. Nico even directly calls her a "little brat" after he realizes the unfairness of her game.
- History Repeats: Played With and actually invoked a bit by Language. The 101st Loop sees her once again facing off against Nico, in his lab, as part of a quest. This time, however, Nico doesn't possess "Unforgettable" much to Language's chagrin, and has Ichico is by his side.
- Imagination-Based Superpower: The objects summoned during her game of Shiritori are based on this. The objects are based on the chosen words, but the exact characteristics and overall form of them are based on the player's imagination. For example, Lan's meteor is made of iron because she imagined it with maximum fire power. Alternatively, the version of the ultimate shield, Aegis, Nico summoned was messy and wobblily in its construction but still blocked the meteor without issue, because he had never seen it before and could not imagine it's appearance but could still perfectly imagine it's function. The game also allows for the manifestation fictional/mythical creatures and objects, like Yokai and Dragons, so long as the player can properly imagine them.
- In-Series Nickname: "Lan" is one for her, used by herself and Soul.
- It's Personal: She has a massive grudge against Nico, due to him being the only negator aside from Unjustice to ever properly kill her. She spends the majority of her time trapped in the Master Room (which totals to 4.6 billion years according to her) looking forward to a rematch, beelines it straight to his lab once she's finally able to escape, and is enraged when she realizes this Nico hasn't manifested his Unforgettable yet. While Soul had already asked her to kill Ichico so the Negators wouldn't be able to learn more about Soul Power from her, Lan instead tries to kill Ichico just to force Nico to manifest Unforgettable. She's so obsessed with this rematch that she forces Fuuko to add Nico and Ichico to the Roundtable under threat of collapsing civilization then and there even though Nico still isn't a Negator therefore normally would not be eligible, just so the two of them can properly face off.
- Killed Offscreen: UMA Language was neutralized by Nico offscreen in the 100th Loop while Andy, Fuuko, and Shen were busy dealing with UMA Spoil, leading to the unification of languages across the world. Subverted in Chapter 200, which shows her final moments against Nico in the 100th Loop, and establishes that said defeat was owed to Nico's use of "Unforgettable", Lan gaining a grudge against Nico for his killing her lasting into the 101st Loop.
- Logical Weakness: While Unjustice is the natural enemy of the Superior Rules in general, Unforgettable is a specific counter to her abilities. Since her combat abilities are based on an all-languages game of Shiritori, Unforgettable's ability to memorize any and all languages with ease allowed Nico to outplay Language easily in the 100th loop.
- Lost Voice Plot: One of her phase two abilities is disabling the ability to speak, which she uses to keep Fuuko from communicating with others at the Union base. She can also invoke this on a global scale if she so chooses and cause a collapse of civilization in the process, which she threatens to do if Fuuko doesn't add Nico and Ichico to the Roundtable so she can face them as part of her Quest.
- Meteor-Summoning Attack: Her first word in her game of Shiritori is "Ryuusei" (Meteor), summoning an iron meteor she specifically mentions was inspired by Fuuko's special attack.
- Parlor Games: Lan's combat abilities are derived from an extreme version of the Japanese word game Shiritori, in which the players are required to say a word which begins with the final kana of the previous word and a player loses if their word ends with the Japanese syllable "n". Her "Deadly Rule Shiritori", however, uses all existing languages, her and her opponent's chosen words will manifest physically and clash against each other, and if a chosen word's Japanese translation ends in the "n" syllable that also counts as a loss.
- The Power of Language: Not only is she the literal manifestation of it, but she explores it more in-depth in her Shiritori game. The power of a summoned word's manifestation depends on Kotodama, the Japanese concept for words having intrinsic soul and spirit. Thus, manifestations that are more steeped in romanticism and imagination like Lance of Longinus and Shen Long are stronger than strictly logical derivations, and can even seem to have an effect on souls like Ichico.
- Puzzle Boss: Literally, as her fight involves a game of Deadly Rule Shiritori where the players to use words to damage their opponent rather than a straightforward fight like with Sick or Beast.
- Signature Headgear: She wears a building-like crown that seems to represent the Tower of Babel, fitting as she is the UMA representing language. Her Phase 3 has the small crown shift into an actual tower.
- Unwinnable by Design: Deadly Rule Shiritori is stacked in her favor to a huge degree. The lose condition is met if a chosen word ends in the Japanese syllable "n", but avoiding that becomes easier and easier as more Languages are added to the game. Considering she is the embodiment of Language itself, its practically impossible to beat her using the game's rules, something Nico realizes early on in his fight with her.
- Villainous Crush: She developed romantic feelings for Nico after spending billions of years obsessed with him following her defeat in the previous loop.
Beast
UMA Beast
The Ninth Master Rule
Click to see his third phase
"I owe that partner of yours. I'll hunt you and take your head as a souvenir, Unluck."
Seat IX of the Master Rule Roundtable, an UMA that represents the concept of roaring beasts and the rules of nature.
- Animorphism: As part of his Cannibalism Superpower, his wolf pelt can shift into form of other animals he's eaten, such as a giant snake to attack opponents or octopus tentacles and suction cups to grapple foes.
- Barbarian Longhair: Under his wolf pelt, he has long, unkempt black hair.
- The Beastmaster: Befitting an UMA representing beasts, he's able to control the creatures of nature, including mammals, bird, reptiles and even marine life. He specifically does so by connecting to their souls, but if the connection is severed by someone else who can see the soul like Fuuko, then the beast is released from his control. His Phase 3 form negates the latter entirely while also allowing him to summon extinct ancient creatures.
- Cannibalism Superpower: Beast can take on the properties of anything living thing he eats, including his fellow beasts. If can get his maw on even a piece of the specific Negator, he can also replicate their abilities as well, such as using Unbreakable to harden his pelt into armor.
- Contemporary Caveman: His design is very clearly based on that of a caveman, with his only clothing being a loincloth, fur cuffs around his upper arms and legs, and a wolf pelt draped across his head.
- Dystopia Justifies the Means: He wants become the strongest rule there is so he can put an end the era of man and restore things to the way they were in past loops, where humans are slaughtered and subjected to horrors by his beasts.
- Failed a Spot Check: Near the end of his fight with the Union, Beast decides to hard focus on Fuuko due to her being leader. In doing so, he fails to notice that Julia has slipped away and gathered Beast's soul fragments from the ancient beasts he revived, allowing Fuuko to charge them with Unluck before they return to Beast's body and ultimately leading to his death.
- Fangs Are Evil: His smile is full of sharp, fanged teeth to emphasize his ferocity and violent nature. They're strong enough to catch bullets mid-air.
- Fossil Revival: In his third phase, he's able to revive long extinct animal species with his "Revive Destruction" attack. Its implied he does this by imbuing his soul into their remains, allowing him to command them without soul lines and while also imbuing them with Unbreakable skin.
- Flunky Boss: He summons an entire herd of different animals to assist him with his fight against Fuuko, Top, and Haruka. For his Phase 3, he also can revive ancient creatures and summon them at will without needing soul chains to control them since he instead imbues pieces of his soul in them.
- Hoist by Their Own Petard: Ironically, him going all out and shifting into Phase 3 is what provided the opening the Union needed to finally put him down. Because he had fragmented his Soul into his various revived fossils to attack, Julia is able to gather the separated soul pieces and then load them with Unluck before they returned to his body, ensuring that Top with Unstoppable and Haruka's "Runner's Regalia" is able to overcome his stolen Unbreakable and destroy his core. To rub salt on the wound, the reason Fuuko was able to come to her "Eureka!" Moment concerning souls was because of his earlier speech that mentioned that souls were the first rule and thus the basis of all of the rules.
- Mighty Roar: One of his abilities is letting out a wicked howl with so much force it can stop an oncoming landslide and so loud it can burst someone's eardrums, which is exactly what he does when he first touches down on earth in the 101st loop.
- Nature Is Not Nice: Cranked up to eleven when he exclaims that he, and by extension ALL beasts (AKA the entire animal kingdom), were specifically created to inflict suffering on humanity.
- One-Winged Angel: Once he realizes Fuuko has begun to unravel the secrets of Soul Power, he opts to go all out and shifts into Phase 3, something only UMA Spring had done in the past via Sun's direct involvement. Beast's phase three allows him to absorb multiple animal souls at once, and revive extinct species to help him attack.
- Pelts of the Barbarian: Every piece of his wardrobe is made of wolf pelt, emphasizing his barbaric and animalistic nature. Said pelt is able to shift into different animal skins depending on what abilities he's using, and can even harden into armor with the aid of Unbreakable.
- The Social Darwinist: Beast's personal philosophy is based on his rule, which is heavily rooted in a "survival of the fittest" mentality. He believes that he who hunts is the winner, and openly invites Fuuko to hunt him back if she truly wants to win.
- Soul Eating: How his Cannibalism Superpower really works, as its devouring the soul of a creature that allows him to use its characteristics and abilities. This is how he's able to perfectly replicate Unbreakable at it's fullest potential, which Haruka points out should be impossible without years of training to master the power. Fuuko corroborates that thought when recalling Billy's failed attempts to replicate it with Unfair, and ultimately realizes that it was by eating a piece of Haruka's soul that he is able to use Unbreakable as if he were an Isshin himself.
- Token Non-Human: As far as other Superior Rules at least, and rather fitting for their namesake, Beast is the only one among the group so far who can adopt less humanoid forms, demonstrated by morphing into a giant snake to fight Fuuko.
- Torso with a View: After his soul is hit with Fuuko's Unluck, Top unleashes an Unstoppable fueled dropkick right to his chest, the force of the impact paired with Haruka's "Runner's Regalia" sending the duo circling the globe several times over before Top is finally able to pierce through Beast's armor. As a result, Beast finds himself with a gaping hole in his torso with his core destroyed, the rest of his body falling apart shortly after as he dies.
Sick
UMA Sick
The Tenth Master Rule
"Ahh, God. I truly am the one and only rule that makes this world turn so beautiful."
The X seat of the Master Rule Roundtable, an UMA that represents the concept of disease, ailments, and overall sickness. As the tenth Master Rule UMA, Sick is one of the strongest UMA and has been around since the very beginning of the loop.
- An Arm and a Leg: Loses his right arm to Rip and Latla's attack, with Unrepair preventing it from regenerating. He seems to have had it replaced through currently undisclosed means.
- Bad Powers, Bad People: Is the literal embodiment of the concept of sickness, just being around him makes all sicknesses worsen exponentially, and even gains more power by extracting said sickness. Is anyone even surprised that he's evil?
- Conducting the Carnage: Literally in this case, as he uses a baton to conduct his Juniors to attack.
- Curb-Stomp Battle: On the receiving end of this once Andy's clone shows up due to Undead negating illnesses to the point where he only escapes with his core intact because of Move's intervention.
- Femme Fatalons: Has claw-like nails he can use to pierce his enemies.
- Half the Man He Used to Be: He gets vertically cut in half by a combo attack from Rip and Latla. Because of Unrepair, he still stuck like this, with his next appearance showing he had get stitched back together and the wound still remains.
- Healing Factor: Is said to have one so potent, the only way the Union can beat him is if they have Rip (Unrepair) on their team. Even after getting sliced in half, he's still alive since his core is still intact.
- Logical Weakness: All the illnesses in the world can do nothing against someone who can't die like Andy. We're also later shown Juiz defeating him in an earlier loop while wearing a gas mask, implying proper protective equipment makes his powers at least a little bit easier to deal with.
- Loves the Sound of Screaming: he considers the crying wails of the sick patients in Rip's hospitals to be "killer music" and his offering to God.
- Major Injury Underreaction: he barely reacts after getting his arm sliced off, and only smirks at Rip's ensuing Badass Boast. Later, he's visibly shocked when Rip and Latla manage to slice him in two, but he shakes it off with Slasher Smile only a second later.
- Necessarily Evil: Likes to see himself as this, claiming he performs population control on humans; he kills some off when there's too many, and leaves them be when there's too few.
- Plague Master: Fittingly for the embodiment of sickness. Not only can he cause illnesses and ailments in others, but just being in his presence causes preexisting conditions to worsen.
- Small Name, Big Ego: To a degree. While he is one of the top Master Rules and is therefore plenty powerful, he's still the weakest of ten, yet he considers himself to be the "only rule that makes the world run so beautifully" despite nine others outranking him and it being clear the only thing that kept Andy from finishing him off was Move's interference. Fittingly, when he arrives back to the Master Room, the other seats mercilessly tease him for his loss.
- The Worf Effect: He's able to withstand the entire Union fighting against him, barley breaking a sweat even after being vertically bisected. Once Andy's clone arrives, however, Sick barely lasts a minute before he's almost crushed to death.
