Aigokeros

Aigokeros is a Road Demon, a being even more wicked and higher-ranked than the demon race, standing at the apex of demonic existence.

He was once the dreaded demon king of Helheim, a hell-like world saturated with extremely dense mana.

He is an irregular existence, not intentionally created by the goddess Arlovinas but born as a bug in the system, much like Ruphas herself.

His body is half composed of mana, emphasizing how unnatural and dangerous his existence is.

Ruphas personally invaded Helheim to deal with him, judging that he was a threat capable of endangering all humanity if left alone.

Rather than destroy him, she subdued and “captured” him, binding that threat to her side and turning it into a weapon and a resource.

Within the Twelve Heavenly Stars of Conquest, Aigokeros carries the title of “Capricorn” and is regarded as one of the most dangerous members.

He is often placed alongside Leon, the strongest of the Twelve, and is called one of the “most fearsome” Twelve Heavenly Stars.

Although his appearance is that of an elderly gentleman, Aigokeros is an extremely powerful, irregular demon king with a mix of cruelty, dark humor, and unexpected comic perversion.

He is fiercely loyal to Ruphas and sees it as only natural that such a monster as himself should be ruled by an even greater monster.

Aigokeros is, in classic demon fashion, arrogant and imperious.

He refers to himself in lofty terms, addresses others with archaic second-person pronouns, and projects the air of an old-world noble.

To his master, he is unfailingly respectful and reverent, using honorifics such as “my great master” when speaking of Ruphas Mafahl.

He treats Ruphas as an existence inherently above him, someone whose right to rule is self-evident.

As a demon, he adores fear and terror.

The sight of others cowering, trembling, or being overwhelmed by dread is pure delight to him, and he often intentionally makes disturbing remarks just to scare people.

Because of these habits, he frequently earns Ruphas’s displeasure.

When he goes too far, Ruphas has no qualms about scolding him, smacking him, or literally tossing him away, leading to some very comedic interactions for a being once feared as a demon king.

Despite his refined speech and old gentlemanly appearance, his inner self is surprisingly perverse.

He is said to rival Scorpio (Scorpius) among the Twelve Heavenly Stars in terms of perversion, even going so far as to try sneaking into his master’s bedroom.

Aigokeros himself does not consider his past surrender or his current servitude to be shameful in the slightest.

On the contrary, he believes that submitting to Ruphas is obviously the correct choice and sees his loyalty as a badge of pride.

He is capable of kindness and familiarity toward comrades and his master, but to everyone else he is utterly ruthless.

To him, those outside his circle are mere dust and insignificant vermin, which underscores that he is, at his core, still a monster.

In his everyday form, Aigokeros has the outward appearance of an elderly gentleman.

This leads many to assume his demeanor is that of a calm, refined old man, which makes his actual personality and perversion all the more surprising.

His true demonic form, however, is far more grotesque and terrifying.

In that form, his head is that of a goat, his torso is that of a man, bat wings sprout from his back, and his lower body is an unstable mass where mana constantly swirls out of control.

When he reveals his true nature, his voice becomes deeply unsettling.

It sounds like glass being scratched, a noise that inspires discomfort and fear and can assault the listener’s psyche on a fundamental level.

For ordinary beings, just hearing that voice is psychologically corrosive and terrifying.

However, Ruphas and the other Twelve Heavenly Stars are so accustomed to him that they are completely unfazed by it.

In the later stages of the story, Ruphas gives him a large scythe to use when he fully unleashes his true form.

This weapon matches his image as a demonic reaper-like figure and enhances the threatening aura he exudes in battle.

Aigokeros’s racial status as a Road Demon places him above the ordinary demon race and even beyond the demon gods in terms of evilness and hierarchy.

He is considered a pinnacle of demonic existence and was powerful enough to rule Helheim by himself.

His stats are immense, making him one of the strongest fighters under Ruphas’s command.

Even at Ruphas’s weakened level 1000 state, Aigokeros is considered capable of winning in a direct confrontation.

However, that assessment only applies when Ruphas is in her significantly limited, “weakest” state.

If Ruphas were to fight seriously at her true potential, Aigokeros acknowledges he stands no chance of victory.

He is still counted among the top-tier monsters of the series, earning the description of “most fearsome” alongside Leon, who is known as the strongest of the Twelve Heavenly Stars.

For the world of Midgards, the fact that such a being was captured and placed under control is a stroke of incredible good fortune.

Aigokeros’s combat style focuses heavily on disruption and interference.

While Aries specializes in indirect debuffs and percentage damage, Aigokeros favors direct interference that hinders enemies head-on.

He also wields powerful lunar-element magic, befitting his “moon” attribute.

Combined with his demonic durability and overwhelming mana, he is well-suited for both offensive and battlefield-control roles.

Even his existence is a form of danger: his half-mana body and irregular nature reflect his status as a living anomaly.

If he had not been subdued, he was projected to surpass even the demon gods in threat level, which is the main reason Ruphas personally went to capture him.

Aigokeros’s representative combat parameters are as follows:

Level: 800 under ordinary conditions.

Level: 1000 when in his Alkaid state.

Level: 1350 under specific conditions, representing his maximum demonstrated power.

Race: Road Demon.

Element (Attribute): Moon.

Primary battle stats:

HP: 72,000

SP: 10,100

STR (Attack): 3,150

DEX (Dexterity): 4,148

VIT (Vitality): 3,453

INT (Intelligence): 6,183

AGI (Agility): 4,140

MND (Mind/Spirit): 5,280

LUK (Luck): 3,000

These numbers mark him as a tremendously well-rounded high-level combatant with a notable emphasis on intelligence and mental power.

His luck is also unusually high, which likely contributes to his survivability and impact in chaotic battles.

Regarding equipment, he later receives a large scythe from Ruphas, meant specifically for use when he reveals his full demonic nature.

This scythe further boosts his offensive capabilities and complements his fear-inducing presence.

General Skill Characteristics

Aigokeros’s arsenal centers around disruption, control, and lunar-element spells.

His style resembles Aries in that both are obstruction specialists, but they differ in approach.

Aries focuses on indirect hindrance, including percentage-based damage and other non-direct methods.

Aigokeros, by contrast, prefers straightforward, brute-force interference that directly cripples the opponent’s ability to fight or recover.

Alongside these disruptive skills, he commands powerful moon-element magic.

This combination allows him to both debilitate enemies and bombard them with destructive spells.

Signature Skill: Denev Algedi

His most notable skill is “Denev Algedi,” a unique (or inherent) ability.

With this, Aigokeros condenses extremely dense mana and fires it as a devastating attack at his target.

The raw damage of Denev Algedi is formidable, but what truly makes it terrifying is its additional effect.

Anyone struck by this technique becomes unable to recover for a certain period of time.

This recovery block does not just nullify healing spells.

It also prevents the target from being aided by items such as elixirs and other powerful consumables.

As a result, being hit by Denev Algedi even once puts the victim in an extremely dangerous situation.

They are forced into a short-term decisive battle, unable to rely on recovery, making it a lethal win-condition skill in prolonged fights.

Origin in Helheim

Aigokeros was born in Helheim, a world comparable to hell and filled with extremely dense mana.

Rather than being created by the goddess Arlovinas, he emerged as a sudden mutation from that mana, spontaneously becoming a demon king.

This makes him an unplanned lifeform, an irregular anomaly similar to Ruphas.

His birth was completely outside the goddess’s scenario, making him a bug in the world’s system.

Ruling Helheim as demon king, Aigokeros inspired fear and awe among demons and other beings.

Within that hellish realm, his existence was absolute, until the day Ruphas Mafahl descended.

Meeting Ruphas Mafahl

Aigokeros’s fateful encounter with Ruphas occurred when she, already known as the Black-Winged Overlord, suddenly invaded Helheim.

Helheim, saturated with dense mana and separated from the normal world, is not a place where someone like a heavenly winged being should easily appear, yet Ruphas did so casually.

Upon seeing Aigokeros, Ruphas evaluated him with a chillingly casual line: she remarked that she had once been called an accursed child and a demon’s spawn, but compared to that, Aigokeros felt “surprisingly thin” to her.

For Aigokeros, who was born from extreme mana density and ruled as demon king, being called “thin” was a shocking statement.

As he confronted Ruphas, he realized through sheer instinct and presence that she was vastly denser and higher in “existential rank” than himself.

This realization shook him to his core; it was obvious that, compared to her, he was the lesser monster.

Recognizing that the difference between their existences was absolute, Aigokeros naturally lowered his head.

Without resistance, he declared, “Ah, you are truly my king…” and offered unconditional surrender and loyalty on the spot.

From that moment on, he considered Ruphas to be his rightful ruler.

He saw no shame in that sudden submission; to him, it was simply accepting the natural order of power.

Loyalty and the Two-Hundred-Year Gap

Aigokeros does not view his obedience as humiliation.

He believes that his sworn allegiance to Ruphas is correct and self-evident, a logical conclusion for a demon king encountering a being like her.

In his eyes, Ruphas Mafahl is the one who should rightly rule Midgards.

He prides himself on being the demonic being who truly and wholeheartedly pledges loyalty to that rightful sovereign.

Two hundred years before the main story, the Seven Heroes betrayed Ruphas and deprived him of his beloved master.

This act enraged Aigokeros, who wanted nothing more than to punish those traitors.

His fury at the Seven Heroes was so great that he temporarily placed himself under the demon gods, an existence he would normally despise and refuse to acknowledge.

He endured their presence purely to gain a position from which he could strike back at the Seven Heroes who had wronged Ruphas.

Reunion in the Era of Merak

Two centuries later, during an incident in the country of Giallarhorn, ruled by Merak the Sky King, Aigokeros crossed paths with Ruphas once more.

In that nation, a major conflict unfolded, and within its chaos he was finally reunited with his revered master.

Upon meeting Ruphas again, Aigokeros immediately returned to her side.

His loyalty never wavered; all that time, his devotion had remained fixed on her.

Ruphas’s initial decision to capture him had always been made for the sake of the world’s safety.

If such a dangerous irregular were allowed to roam free, he could have become a threat surpassing even the demon gods.

By binding him to her service, Ruphas both contained that danger and turned it into a strength for Midgards.

From the world’s perspective, having Aigokeros captured and controlled was a fortunate accident of history.

Aigokeros is a major supporting character in “A Wild Last Boss Appeared!”.

He represents the demonic, chaotic side of Ruphas’s followers, but also shows how even monsters can find a place under her rule.

As one of the Twelve Heavenly Stars of Conquest, he works within Ruphas’s forces, leveraging his disruptive skills and terrifying presence in battle.

He acts both as a powerful trump card in combat and as occasional comic relief thanks to his perverse antics and over-the-top devotion.

His interactions with other members of the Twelve Heavenly Stars often highlight contrasts in personality.

He especially stands out when juxtaposed with more proper or earnest members, as his gentlemanly exterior hides an extreme nature.

The series uses Aigokeros to explore themes of irregularity and destiny.

Like Ruphas, he is a bug born outside divine planning, yet he finds meaning and direction precisely by serving another irregular being.

Ruphas Mafahl

Ruphas is, in Aigokeros’s mind, his absolute and rightful king.

He views her existence as fundamentally superior to his and believes his submission to her is the natural order of things.

He expresses his loyalty in grandiose, reverent language, often calling her “my great master” or similarly exalted titles.

Any harm or insult directed at Ruphas ignites his wrath, as proven by his reaction to the Seven Heroes’ betrayal.

Even when Ruphas physically disciplines him for going too far with his scary or perverse behavior, he remains unwaveringly devoted.

The dynamic between them is both humorous and genuinely respectful, with Ruphas treating him like a troublesome but valuable subordinate.

Other Twelve Heavenly Stars

Among the Twelve Heavenly Stars of Conquest, Aigokeros is considered one of the most dangerous, alongside Leon.

His reputation rests on his raw power, his terrifying skills, and his willingness to engage in psychological warfare.

He is often compared to Scorpio in a less flattering way, as both are infamous for being perverts.

Despite that, they are still trusted as comrades and assets in Ruphas’s army.

The other Twelve are unfazed by his horrifying true voice and monstrous form, showing how accustomed they are to extreme beings.

This familiarity also highlights the extraordinary level at which Ruphas’s inner circle operates.

Aigokeros’s name and seat correspond to the constellation Capricorn.

His existence as a “bug” mirrors Ruphas’s own nature as an irregular, strengthening the thematic link between master and servant.

The fact that he was strong enough to potentially defeat a weakened level 1000 Ruphas, yet willingly submitted instead of fighting, underscores how overwhelming her true presence is.

His mix of refined gentlemanly appearance and deeply perverse, sadistic nature makes him both unnerving and darkly comedic.

For Midgards, the “capture” of Aigokeros is one of those rare moments where the world gets incredibly lucky: a potential apocalyptic threat turns into a fiercely loyal guardian.
