The sky… was red.
Not the warm red of a sunset, nor the gentle hue of twilight.
It was the crimson of blood flowing on a battlefield.
Heat.
The stench of burning iron.
Screams.
Amid the ruins of an ancient castle long stripped of its glory, a young man stood motionless.
His body was dirtied with dust and blood, but his face remained clean not because he was unharmed, but because he simply didn't care.
Kazuki Arata.
That was the boy's name.
In his old world, he was just an ordinary student.
A high schooler living in emptiness.
Wake up, go to school, eat alone, go home.
Days passed like a lifeless cliché, devoid of color.
But everything changed when a strange light appeared in the sky above his classroom.
"Interdimensional summoning," they called it.
Kazuki was summoned to a world named Aeralis a land ruled by corrupt kings, false heroes, and people too afraid to rebel.
A world begging for salvation… while hiding a truth more rotten than Kazuki's own reality.
"I'm not a savior," he told them the moment he appeared at the summoning altar.
"I can't even save myself."
The ones who summoned him wept, pleaded, knelt.
They called him the King of Destruction, a figure from an ancient prophecy said to bring down the world's system and usher in a new era.
But what they wanted was a savior in white, not a boy with lifeless gray eyes and a complete lack of interest in everything.
Yet, the moment Kazuki touched the soil of this world, something inside him awakened.
Void Authority.
An ancient power feared even by the gods.
With it, Kazuki could nullify magic, erase existence, and reject reality itself.
He didn't know where the power came from.
But he knew one thing:
this world could be destroyed.
Among the ruins of fallen civilizations, Kazuki met them five girls, each carrying wounds, buried pasts, and truths the world wanted hidden.
Elira Valtoria, first princess of the Kingdom of Light.
Raised on ideals and honor, yet disgraced by her own nation.
She came to him seeking redemption but found herself bound to a man who no longer believed in the light.
Seraphine, a spirit of light trapped within a mortal body.
Gentle, compassionate, and the one who understood Kazuki's loneliness the most.
She never asked for love only to walk beside him.
Myria Nocturne, a young demon exiled for rejecting violence.
Fierce, wild, and sarcastic yet she always returned to Kazuki's side, even when scorned.
To her, he was the only one who never saw her as a monster.
Nyx Velshade, an assassin from the shadows.
She came to kill him… but ended up rereading his letters under the moonlight.
Cold and deadly, yet slowly melted by his brutal honesty.
And then, one more…
A figure yet to show her true face.
Someone closer than he realizes.
Someone pulling the threads of fate behind the scenes.
Kazuki never intended to create a harem.
He didn't care for love, fame, or saving the world.
But they came not because he rescued them,
but because he was different.
He was the only one who dared to say,
"This world isn't worth saving."
And strangely… they chose to stay.
Kazuki walked over the ashes of a fallen city.
The wind tugged at his tattered black cloak.
Behind him, five shadows followed.
Ahead thousands of enemies with swords, spells, and hatred in their eyes.
"Why don't you stop?" Elira asked.
Kazuki paused, staring at the blood-red sky.
"Because if I stop… the world will stay the same."
He clenched his fists.
Black aura leaked out like smoke.
"And if I can destroy it… then maybe I can choose again what kind of world is worth living in."
In this world, heroes are tools. Kings are tyrants. And love… is a weakness. But to Kazuki Arata, the world isn't something to be saved. It must be destroyed so he can find something more honest, more real… perhaps even a love that isn't a lie.
