Billy Alfred

Billy Alfred is a Negator whose true ability is UNFAIR (Unfair), allowing him to copy other Negators’ powers and break the “one person, one ability” balance.

Within Union, he initially poses as the Negator of UNBELIEVABLE (Unbelievable), a gun-based ability, while serving as the Round Table’s Seat III and often acting together with Tatiana, Seat V.

He is visually recognizable as a suited gunslinger with sunglasses, unshaven stubble, and twin revolvers.

Despite his laid‑back, goofy demeanor within Union, he is in fact a cold, calculating realist who will sacrifice civilians if it helps him reach his ultimate objective of killing God.

Billy has the vibe of a “cowboy in a suit.”

He wears a suit with the jacket casually draped over his shoulders, the tie loosened, and the shirt collar slightly open, giving him a deliberately relaxed, somewhat sloppy silhouette.

He sports unkempt facial hair and always wears sunglasses, which also help visually signal his blindness.

At his hips he carries two revolvers in twin holsters, emphasizing his style as a classic gunman.

On his feet he used to wear shoes fitted with spurs, which create clear sounds when he walks.

These spurs were designed, under Nico Vorgeil’s supervision, to help him “see” via sound and echo, complementing his sharpened hearing.

The Union emblem is attached to the right collar of his shirt, marking his official membership and Round Table rank.

After he forms a partnership with Tatiana, he often stops using the spurs when she is present, as she becomes his “eyes” in the field.

Billy presents two sharply contrasting faces: the gentle, goofy mentor inside Union and the ruthless strategist behind UNDER.

Easygoing “playful uncle” side

To most Union members, Billy looks like a warm, somewhat silly older man who is easy to approach.

He usually refers to himself with the first‑person pronoun “Boku,” which in context gives him a soft, mild tone.

He is calm and responsible on the surface.

For example, when Tatiana attacks Andy out of anger over Gina Chamber’s death, Billy calmly warns her that “fighting between members is strictly forbidden,” taking on the role of the level‑headed adult.

At the same time his behavior is full of comedic gaps and airheaded remarks.

When Juiz d'Arc redirects Tatiana’s beam weapon toward him, he only reacts with lines like “Huh?” and “It’s kinda hot,” failing to realize he is being targeted.

Even when Tatiana frantically yells that she does not want to kill him, he casually asks, “Wait, am I going to die?” showing almost zero tension.

Through such scenes, the story establishes him as an unthreatening, lovable “uncle” rather than a cool, edgy gunman.

He often misses visual context due to his blindness, which is played for humor.

When Fuuko Izumo half‑strips and hugs Victor (Andy’s original self) to restrain him, the other members are shocked, but Billy only asks “What? What’s happening?”, clearly not understanding the scene.

He loves sweets and even supervises the flavor of cakes, especially products Tatiana can eat.

In everyday scenes and official novels, he helps with events like Halloween by cooking and offering kind, fatherly advice to Tatiana.

Because of his relaxed nature, his comrades sometimes play gentle pranks on him.

Tatiana once secretly “borrowed” his gun while he slept (which earned both of them a fierce scolding from Juiz, especially aimed at Billy).

Top and Gina have been shown shaving his stubble without asking.

When he picks up Phil, the child pulls out Billy’s beard hairs without hesitation, underlining how safe and approachable he feels to everyone.

Overall, his Union persona is that of a sweet, affectionate adult who can be scolded, teased, and clung to by all ages.

This image will later make his betrayal all the more shocking.

Cold strategist and true nature

Billy’s true personality is far more ruthless than his gentle façade.

As the boss of UNDER, he is a hardcore realist who will not hesitate to sacrifice countless civilians if it leads to the destruction of God.

He admits that from the very first time he met Juiz and joined Union, he never once truly trusted her.

Instead, he intended from the beginning to use Union as a tool to reach his own objective: to kill God and overturn what he sees as an unfair world.

During the Round Table meeting for the quest loaded with the “100th penalty,” Billy finally reveals himself.

He betrays Union mid‑conference, takes control of the UMA Burn, and attempts to steal both the Round Table and Apocalypse.

Fuuko manages to snatch Apocalypse back, so Billy retreats for the time being.

From that point on, he openly opposes Union as the leader of UNDER.

After his betrayal he adopts an intentionally villainous attitude, acting more openly cruel and arrogant than before.

However, this exaggerated cruelty is actually tactical: he wants the Union Negators to hate him so he can copy more abilities with UNFAIR.

At the same time, this behavior reflects his resolve to shoulder all the sins and blame alone.

By positioning himself as the ultimate villain, he aims to gather hostility onto himself and spare others from shouldering that burden.

Billy is blind, a fact that the story hints at early on and then confirms explicitly through Tatiana’s flashback.

Even before joining Union, during his mercenary days, he was already fighting on battlefields despite his lack of sight.

He survives and excels thanks to an extremely sharpened sense of hearing.

He reads his surroundings through sound, echo, and subtle vibrations, building a mental map from auditory cues.

The spurs on his shoes are a key tool in this system.

As he walks, the metal sound bounces off nearby objects, and Billy interprets these echoes much like a rudimentary sonar.

However, certain environments remain difficult for him.

Official bonus comics state that areas with water surfaces are particularly hard to read for him, making water one of his weak points.

When he first joins Union, he relies on a white cane, like many blind people in the real world.

Later, under Nico’s supervision, he transitions to the spur‑equipped shoes that better match his combat style and auditory sensing.

Once Tatiana joins Union and forms a team with Billy, he often stops wearing the spurs around her.

Her spherical barrier armor allows her to visually monitor the battlefield and provide guidance, effectively becoming his “eyes.”

In short, Billy is a high‑level combatant who has adapted to and overcome a major disability.

His blindness shapes both his fighting style and his everyday interactions, contributing to his gentle, slightly “out of the loop” persona.

Billy is a Negator, a human who embodies a fundamental “negation” of the world’s rules.

He possesses one true Negation ability, UNFAIR, but he initially registers and explains himself using a false ability, UNBELIEVABLE, to conceal his secret.

UNBELIEVABLE (Unbelievable) – registered ability and cover story

Type: Self‑targeted, gun‑limited ability (as officially described)

Nature: Forced activation is implied, but specifics are never formally detailed to Union

According to the explanation he gives Tatiana, UNBELIEVABLE is a gun‑centric Negation that guarantees hits in an impossible way.

If Billy deliberately shoots in a direction where the bullet “absolutely should not” hit the target, the bullet will ricochet or take an improbable trajectory so that it will certainly strike the target.

This ability denies the “obvious” expectation that a bullet fired wildly away from the target will not hit.

Instead, his shots turn into miraculous, unbelievable hits that defy common sense, as though probability itself bends to his will.

Tatiana is the only Union member who is fully briefed on this supposed detailed mechanism.

Understanding it, she can erect barrier fields that serve as ricochet surfaces for Billy’s bullets, creating cooperative attacks where she lays the terrain and he guarantees the hit.

To the rest of Union, Billy simply reports that he has a “gun‑related Negation ability,” leaving the deeper details vague.

This helps disguise the existence of UNFAIR and frames any oddity in his marksmanship as a quirk of UNBELIEVABLE.

It is later clarified that the impossible ricochets and impossible hits are not actually a supernatural gun‑ability.

They are the product of Billy’s own extreme technique, battlefield experience, and the misdirection of his false registration.

UNFAIR (Unfair) – true Negation ability

Type: Self‑targeted, voluntary activation

Effect: Copies and stores multiple Negator abilities, breaking the “fair” rule of one ability per Negator

Theme: Denial of fairness; initially triggered by hostility, later by admiration

UNFAIR allows Billy to copy and hold more than one Negation, overturning the implicit “fairness” that each Negator has only one ability.

This makes him a walking arsenal of powers, especially dangerous because he already possesses top‑tier combat skills.

There are, however, strict conditions for copying.

Originally, Billy can only copy the ability of a Negator who regards him as an enemy or actively bears hostility toward him.

His betrayal of Union is therefore more than just a strategic choice; it is also a necessary trigger.

By becoming a traitor, he ensures that many powerful Negators come to hate him, fulfilling the condition for UNFAIR to copy their powers.

Using UNFAIR, he copies several major abilities, including:

UNDEAD (Undead) – the regenerative ability originally belonging to Andy / Victor

UNJUSTICE (Unjustice) – Juiz’s ability

UNSTOPPABLE (Unstoppable) – which grants unstoppable movement at the cost of bone fractures

UNMOVABLE (Unmovable) – the ability to become unshakably fixed or anchored

Combining these powers makes him terrifyingly versatile.

For example, he can offset the severe physical damage from UNSTOPPABLE’s high‑speed charges by instantly regenerating with UNDEAD.

He even heals his blindness using the regenerative powers of UNDEAD.

However, UNFAIR is still bound by psychological rules and relationships, not just raw power.

Because Fuuko never truly saw Billy as an enemy, he cannot copy her UNLUCK (Unluck).

Later, when Juiz stops viewing him as an enemy, he loses access to her UNJUSTICE, showing that both acquisition and retention depend on his current relational stance.

After a timeline loop, Billy’s own internal recognition changes, and with it, UNFAIR’s condition.

In this new loop, he copies abilities not through enmity, but by genuinely recognizing the target’s strength, a condition grounded in admiration or awe rather than hatred.

This shift embodies a change in his emotional foundation from antagonism to a kind of respect‑driven desire.

UNFAIR thus becomes a “negation of fairness rooted in envy and admiration,” making his power less about being hated and more about sincerely acknowledging others’ greatness.

Combat Style and Expertise

Even without Negation powers, Billy is a highly skilled gunfighter and tactician.

He has a background as a mercenary leader and is able to identify specific types of firearms by sound alone.

He specializes in fast draw and accurate revolver shooting, turning handguns into precision tools in any situation.

His auditory awareness, honed by blindness, enhances his spatial judgment and reaction time beyond an average sighted shooter.

By combining this combat talent with copied Negations, Billy becomes one of the most dangerous individuals in the setting.

His position as Seat III of the Round Table already signals his high combat ranking within Union.

Tatiana

Tatiana is the Round Table’s Seat V, a girl who lives inside a spherical armored weapon called “Sphere.”

Billy spends a great deal of time with her, and the two operate as a close combat unit.

He takes care of Tatiana in many everyday aspects, from bringing her food to emotionally supporting her.

Because Tatiana’s Negation makes normal eating difficult, Billy leverages his love of sweets and baking to design desserts she can enjoy safely, such as special cake bars.

Tatiana deeply admires and trusts Billy, seeing him as both protector and family.

Artwork and scenes show her adjusting his clothes from behind, clinging to him, or working in perfect sync with him in battle.

Billy likewise treats her with a gentle, almost fatherly affection.

In official novel material, he patiently helps her navigate social events and offers advice, reinforcing his role as her closest understanding adult.

After his betrayal, the emotional cost to Tatiana is immense, as the person she admired most reveals himself as an enemy.

For Billy, part of his self‑sacrificing villain act is to shoulder her hatred as well, believing this is necessary for his greater mission.

Juiz d'Arc

Juiz is the leader of Union and the one who originally recruits Billy.

She approaches him when he is broken and despairing, inviting him to join the struggle against the true cause of his tragedy: God.

On the surface, they seem to share a common goal and mutual trust.

In reality, Billy never fully opens his heart to Juiz, continuing to see Union only as a means to an end.

Their relationship is a complex mix of genuine shared purpose and deep betrayal.

Juiz’s faith in him is shattered when he reveals himself as UNDER’s boss, steals abilities, and attempts to seize the Round Table and Apocalypse.

Later, in a new loop, Billy’s internal perspective shifts.

As a result, his copying condition for UNFAIR aligns with recognizing the strength of others—something that implicitly acknowledges the merit of people like Juiz rather than purely opposing them.

Fuuko Izumo and Andy / Victor

Fuuko and Andy form the central duo of Undead Unluck and are crucial to Billy’s plans and ideology.

While he interacts with them often as Seat III, his deeper interest lies in Andy’s UNDEAD and Fuuko’s UNLUCK.

He eventually copies UNDEAD from Andy / Victor, gaining their regenerative might.

Fuuko, however, never truly views Billy as a personal enemy, so UNFAIR fails to activate on her, leaving UNLUCK beyond his reach.

In the new timeline, Billy encounters the organization during the Brozha conflict.

There he fights a one‑on‑one duel with Fuuko, during which he comes to genuinely acknowledge her strength.

This recognition, grounded in admiration rather than hostility, fulfills UNFAIR’s new condition.

After this, he joins Union again under altered emotional circumstances, hinting at a more cooperative relationship.

Before joining Union, Billy Alfred serves as the captain of a mercenary unit called Horizon Balance.

Despite his blindness, he leads soldiers in real wars, proving his capability through sharp hearing, disciplined tactics, and lethal marksmanship.

At this time, he is already married and has a family.

His wife is named Veronica, and together they have a daughter named Betty.

During one conflict, Billy’s unit is hired both to secure victory in the war and to locate an ancient super‑weapon.

In the course of this prolonged battle, Negation abilities manifest in Billy, his subordinate Teller, and their enemy Creed Deckard.

The sudden introduction of Negations complicates the situation and extends the war far beyond expectations.

This prolonged conflict delays Billy’s return to his homeland.

When the war finally ends and Billy comes home, he discovers his worst nightmare has already happened.

His beloved wife and daughter have died in an accident, leaving only their gravestones behind.

Billy collapses in front of their graves, drinking in the rain, consumed by grief and disbelief.

He understands that if the war had not been inexplicably prolonged—an outcome tied to the Negations—they might still be alive.

This tragedy makes Billy acutely aware of how unfair and cruel the world truly is.

He had fought under the simple, noble belief of “saving people,” but in the end, the world repaid him with senseless, arbitrary loss.

It is in this broken state that Juiz appears before him.

She invites him to join Union and fight not just monsters and UMAs, but the very root cause of such repeated tragedies: God and the rules imposed on the world.

Billy accepts, seeing in Union a path to revenge against the unfairness that took his family.

However, from the beginning, he views Union as a tool and never fully offers his trust, planting the seeds of his eventual betrayal.

Within Union, Billy sits at the Round Table as Seat III, quietly building rapport and trust with the other members.

He often serves as Tatiana’s handler and partner, participating in missions and internal meetings with a mild and relaxed demeanor.

During the quest announcement with the 101st penalty looming, Union prepares to face a mission of unprecedented severity.

In the middle of this crucial Round Table meeting, Billy reveals his true allegiance to UNDER.

He seizes control of the UMA Burn, aiming to use its power along with the Round Table and Apocalypse to further his own plan.

Fuuko manages to rescue Apocalypse, preventing him from securing every key asset, forcing Billy to retreat.

From this point onward, Billy becomes one of the main antagonistic forces opposing Union.

Armed with multiple copied Negations and newly restored sight, he embodies the ideal of “fighting unfairness with even greater unfairness.”

His actions, motives, and hidden grief deeply impact the emotional and ideological core of Undead Unluck.

Later loops and altered relationships suggest that his path is not fixed, and that recognition, admiration, and changed perspectives can transform how UNFAIR operates—and how Billy positions himself in the struggle against God.

When tagged simply as “Billy,” he can be confused with characters of the same name from other franchises.

Fans posting art and fiction typically use tags like “Billy Alfred” or “Billy (Undead Unluck)” along with “Undead Unluck” or “Undead Unluck (series)” to make searches easier.

Among readers, early impressions of Billy focus on his cuteness and charm more than on his coolness.

His silly lines, sweet tooth, and tender interactions with Tatiana make fans describe him as “adorable” or “precious” rather than just a rugged gunman.

Only later, when his true role as UNDER’s boss is revealed, do fans re‑evaluate the earlier scenes in a harsher light.

This duality—gentle caretaker and cold mastermind—is a big part of why Billy Alfred stands out so strongly in the series.
