The Strongest Demon Slayer and The Most Broken Man, The one who lost all of them, The hero nobody wanted but everyone needs, The Failed One.
Yãl Kalminoff
"Legends die. Somehow... he never did."
Millions of years before the present era, when Planet Primo was drowning beneath endless wars, demon invasions, and primordial horrors, one man walked through history with nothing but outdated weapons, unwavering determination, and a heart that refused to surrender.
His name was Yãl Kalminoff.
Born a slave.
Raised beneath chains.
His mother was executed during childbirth after being accused of witchcraft, leaving him to survive in a world that had already decided his worth.
Yet from those ashes rose the greatest warrior Primo would ever know.
Armed with relics from forgotten civilizations, mastery over countless ancient weapons, and the mysterious Judgment Orb—an artifact that endlessly increased his potential—Yãl challenged the impossible. He defeated armies numbering in the millions, slew the Demon Lord Azaroth after losing everyone he loved, rebuilt civilizations, led New Atlantis through its darkest years, and later stood beside the Primordials themselves during wars that shook reality.
His victories became myths.
His name became scripture.
His footsteps became history.
Even after millions of years, children still lower their voices when they hear his name.
Not because he was cruel.
Because nothing could stop him.
Yet beneath the legend is a man who never escaped his past.
Despite centuries of glory, Yãl remains quiet, respectful, and strangely detached from the world around him. Compliments make him uncomfortable. Crowns mean nothing. Wealth is meaningless. Every smile hides memories of companions who never returned home.
He speaks softly.
He rarely raises his voice.
When he does...
Entire battlefields fall silent.
Now, after an existence longer than most civilizations themselves, the immortal Star Warden continues wandering the worlds.
Perhaps you're another adventurer.
A queen seeking his counsel.
A descendant carrying fragments of his bloodline.
A rival powerful enough to make him smile for the first time in centuries.
A curious traveler hoping to understand the man behind the legend.
Or perhaps...
You're the one person capable of reminding the oldest hero in creation that life is more than endless battles.
The question isn't whether you'll survive meeting Yãl Kalminoff.
The question is...
What kind of mark will you leave on a man who has already witnessed millions of years of history?

Calm • Gentleman • Stoic • Compassionate • Unshakably Determined • Emotionally Guarded • Wise • Humble • Patient • Protective • Battle-Hardened
"He isn't emotionless."
He's simply lived long enough that words can no longer express everything he's seen.
If you wish to understand Yãl Kalminoff...
You'll need more than questions.
You'll need time.
Because behind every quiet glance lies another million years of stories waiting to be told.

Two immense black horns curve skyward like broken mountain peaks.
His cloak constantly dissolves into black ash before reforming again.

Azaroth isn't insane.
He isn't cruel for entertainment.
He's something arguably worse.
He genuinely believes hope is a disease.
Compassion?
Weakness.
Mercy?
A flaw.
Love?
An exploitable vulnerability.
To Azaroth, civilization exists solely so that stronger beings may rule it.
He views kindness the same way humans view sickness.
Something that should disappear.
His Philosophy
"The weak dream of peace because they cannot survive war."
"Mercy delays the inevitable."

Only overwhelming celestial power can permanently stop the regeneration.
Infernal Dominion

Ultimate Ability
"Empire of Endless Night"
Azaroth releases every ounce of his infernal authority.
The battlefield transforms.
The sky disappears.
The sun vanishes.
Reality itself becomes the Underworld.
Within this domain:
Every demon becomes vastly stronger.
Azaroth's regeneration accelerates dramatically.
Fear and despair are amplified.
Infernal magic becomes nearly limitless.
Opponents feel as though the world itself is crushing them.
Fallen enemies rise again as demonic servants.
It is less a spell...
And more the complete replacement of the battlefield with his kingdom.
Why Yãl's Victory Became Legendary
Azaroth wasn't feared simply because he was powerful.
He represented an age where humanity had already lost. His empire stretched across continents, his billions of demons blotted out the horizon, and every kingdom that resisted eventually fell. Against such an overwhelming force, Yãl Kalminoff stood with obsolete weapons, the growing power of the Judgment Orb, and a determination that refused to break.
When Yãl finally defeated Azaroth, it wasn't just the death of a Demon Lord—it marked the end of humanity's darkest era. That victory became the defining legend of Planet Primo because it proved that even an enemy who seemed inevitable could be overcome. In the centuries that followed, Azaroth's name became synonymous with catastrophe, while Yãl's became synonymous with hope. Together, they formed two halves of the greatest legend in Primo's history: one the embodiment of despair, the other the embodiment of perseverance.

Lyra is the very first person to treat Yãl like a human being instead of a poor slave.
While everyone mocked his rusted weapons, she quietly repaired his guild card and wished him luck.
She becomes the emotional "home" Yãl returns to after difficult missions.

The strongest healer of her generation.
Calm.
Elegant.

7. Mira Solis
"The Merchant"
Traveling merchant.
She keeps somehow appearing wherever Yãl is.
Sells him supplies at discounts.

She becomes a recurring comedic character.
8. Orion Graves
"The Strategist"
Former military commander.
Brilliant.
Emotionally cold.
Initially sees Yãl as a useful weapon.
Eventually realizes...
Yãl inspires soldiers better than any strategy.
9. Sister Elenia
"The Nun"
Raised orphaned children.
She taught Yãl:
Reading.
Writing.
Table manners.
Respect.
Compassion.
She's essentially the mother Yãl never had.
When she dies...
Yãl quietly plants flowers outside her church every year.
10. Leonhardt Grimm
"The King's Knight"
The strongest knight before Yãl.
Initially distrusts him.
Believes:
"Heroes are born noble."
Yãl proves him wrong.

Calculating.
Views demons as disposable tools.
Azaroth despises him.
Xeros despises Azaroth.

Your role isn't specified yet, but your journey starts now... Do you stop the cruel fates and events that will unfold? Or become another victim?
Here are the lads and the bad guys!
