Shadow Breathing: Origin
A demon spared his life… but not out of mercy.
It was a decision that would one day threaten the balance of two worlds.
Raizen was just an ordinary boy—
until one night, everything was taken from him.
His family was slaughtered.
His home was drowned in blood.
And standing in the middle of it—
Was something inhuman.
“Why…?” Raizen’s voice trembled.
The figure smiled.
“Because you survived.”
Instead of killing him, the demon did something far worse—
It changed him.
A dark power was forced into his body…
A power that didn’t belong to humans.
The Awakening
That night, Raizen didn’t just lose everything—
He awakened something forbidden.
Shadow Breathing.
A power that allows him to control shadows—
but slowly, he realizes:
He isn’t controlling it.
“It moved… before I did.”
The shadow reacts.
It listens.
It learns.
And with every battle, it grows stronger.
The Journey Begins
Driven by revenge, Raizen steps into a world of hunters, demons, and hidden forces.
But revenge is not his only problem.
Because as he grows stronger—
Something else begins to notice him.
“You’re not normal,” Kagen said.
Raizen didn’t deny it.
“…I know.”
The Truth Unfolds
Raizen soon learns a terrifying truth:
His power doesn’t come from this world.
It comes from something beyond it.
A place between worlds.
A space that cannot be fully understood.
And Raizen—
Is connected to it.
“You’re not just using the power,” Kagen warned.
“…You’re becoming part of it.”
The Bigger Threat
As Raizen grows stronger, he attracts attention from powerful forces:
The Circle — beings who observe and control balance
Entities beyond the source — things that don’t belong to reality
Others like him… who all failed
“You are not the first,” a voice echoed.
Raizen’s eyes narrowed.
“…Then where are they?”
“…Gone.”
The Main Conflict
Raizen faces a terrifying dilemma:
If he uses his power, he gets stronger
But the more he uses it… the more he loses himself
“There is a line,” a mysterious figure warned.
“…Once you cross it, you don’t come back.”
But Raizen makes a choice.
“I’m not stopping.”
The Turning Point
He crosses that line.
And everything changes.
The shadow is no longer just power—
It becomes a gateway.
A bridge between worlds.
“You are close to completion.”
“…Completion of what?”
“…Becoming the passage.”
Core Theme
This isn’t just a revenge story.
It’s about:
Identity — Am I still human?
Control — Am I using the power, or is it using me?
Evolution — What happens when power changes your existence?

actually the story is interesting, but what makes the quality of this novel decrease drastically is the mc's decision in taking traits, i don't know why he didn't even copy abilities like zoro's 3 sword technique, nami's navigation ability, some of sanji's abilities, arlong's underwater breathing ability, etc. he only took/copied the most striking traits, i mean what's wrong with having more traits??
