The universe burned.
Shattered stars drifted across the void, and fragments of broken realms fell into darkness. Amid the silence, a lone figure floated, his body breaking into silver dust.
He could not remember his name. He could not remember who he was.
Before his consciousness faded, he heard a soft, warm voice.
"No matter how many worlds… I will find you."
A hand reached toward him—
But he couldn't hold on.
---
He was reborn in a quiet hospital room.
The newborn did not cry.
"Is he alive?" the doctor panicked.
The baby's dark eyes opened slowly—clear, empty, and terrifyingly calm.
He was alive. But he felt nothing.
---
He grew up that way.
A boy who never smiled. Never cried. Never called for his parents.
He only stared at the world in silence.
A dog wagged its tail and licked his hand. He only blinked.
Children laughed and pushed each other on the playground. He sat alone, unmoving.
Teachers praised his intelligence, but their voices trembled.
He lived without attachment, without purpose.
His days were a quiet, endless winter.
And sometimes, in the darkness of sleep, he dreamed.
A warm hand reaching for him.
A voice whispering his name.
A light that felt like… home.
But every time he opened his eyes, the world was still the same—
cold, empty, and silent.
The dream faded.
Nothing changed.
---
Eighteen years later, under the pale glow of the streetlamps, he walked home alone.
Screech—!
Bright headlights cut through the darkness.
The world spun, and his body went cold.
No pain.
No fear.
No regret.
When he opened his eyes again, he was floating in a white void.
> [Ding! Binding complete. Welcome, Host #000.]
A calm, mechanical voice echoed in his mind.
> "Your task is to travel through worlds.
Take over the bodies of those who have died with regrets…
and help them fulfill their final wishes."
> "When their wishes are fulfilled, you will leave their world."
The boy blinked, expressionless.
"…I understand."
> [First Mission Initializing…]
Light swallowed him whole.
And so began the journey of an emotionless wanderer, stepping into countless lives—
Unaware that somewhere, in every world…
Someone was waiting for him.
