"In Another Life, I Was Sasuke Uchiha…"

In the final, war-torn moments of the Shinobi world, Sasuke Uchiha gives his life to protect Boruto from Code's ruthless ambush. His soul, heavy with regrets and unfulfilled redemption, should've vanished into the void...

But fate isn't finished with him.

---

Long ago, when Sasuke Uchiha died protecting Boruto, his soul should have disappeared forever.

But someone stopped that from happening.

That someone was Derkila, the former Demon King.

He used powerful forbidden magic to pull Sasuke's soul into another world — the world of humans and demons. But by doing this, Derkila broke the law of the gods. And because of that, his own soul was destroyed. [ Thats why he disappear in demon world many years ago ]

Derkila's soul split into two parts:

His good side – the part of him that was kind and pure.

His magic – the powerful energy inside him that had no emotions or thoughts.

His good side was reborn as a human child — [ After many many thousands years after he lost all of his memories ]That child was Iruma Suzuki. [ The name was given by his mother ]

Meanwhile, his magic side became something artificial. It wasn't human or demon. It became its own thing, wandering the demon world, waiting for its purpose.

At the same time , Sasuke's soul fused with the soul of Iruma.

Now, Iruma carries two souls inside him:

One is Sasuke's soul: powerful, serious, and full of pain.

The other is Derkila's good soul: kind, honest, and gentle.

But there's still a third piece —Derkila's magic.

The 2 different soul merge into one. One soul is good and another soul is sasuke soul .

But what happen the other Being Magic ? Well it goes to on artificial.

Born to parents who never wanted him, Iruma is raised in silence — not with love, but as a burden. Used, ignored, and forced to obey. A vessel. A tool.

Until one day, he's sold to a demon.

But destiny, it seems, has not abandoned him. Because the demon who buys him is not cruel — but kind. Sullivan, one of the 13 Crown Kings of the Netherworld, adopts him with love and pride. For the first time, Iruma feels warmth. A home. A family.

Yet deep inside him, the remnants of a warrior's soul stir.

Iruma keeps his master sword close.

For when he awakens that power… 

But how did it begin?

Three years before his arrival in the Netherworld, Iruma met a man —A silhouette at the cliff's edge. Cloaked in obsidian, wind coiling around him like shadows. His name was Kuro Akari. A swordsman, quiet and composed, who radiated power and peace alike.

Kuro saw the boy Iruma and took him under his wing.He trained him, encouraged him, believed in him.And for the first time… Iruma remembered what kindness felt like.

But tragedy is never far behind.

A powerful, ancient demon Ruler — Aarimon — crossed into the human world. A being so strong, the sky trembled at his presence. When Iruma saw him, he couldn't breathe. Couldn't speak. Couldn't move. [ He came to earth because of one certain prophecy. ]

And then… Kuro stepped in.

To protect him.

The battle didn't last long. Aarimon toyed with the swordsman — and killed him.

Right before Iruma's eyes.

That moment shattered him.

Just like the massacre of the Uchiha. Just like losing his brother.Just like the fall of everything he loved.

Grief gave birth to power.

Iruma's sorrow awakened the Raven [Red] Eye — a mutated force beyond the Mangekyō, born not only from loss, but from two fused souls screaming in pain. He took Kuro's cursed blade. Vengeance wrapped around him like armor. His strength exploded. So did his hate.

But something else also awoke.

A quiet, passive ability — a remnant of the boy who still cared: Soul Connect.

If someone speaks to Iruma from the heart… he can't refuse. No matter how cold he tries to be. No matter how much Sasuke's soul urges him to pull away.But if someone approaches with guilt, or deception, or malice — Iruma feels it.Their intent. Their shadows. Their lies. Like a sixth sense that pierces the mask of words.

He knows when someone is true.And when they are dangerous.

In a world of demons and contracts, of lies and betrayals —He is the only human. The only shinobi. The only soul with two fates.

He is Iruma Suzuki.But once…He was Sasuke Uchiha.

And this time,What will be the Out come? 

The Great Demonic War ! Will happen .

Which side will netherworld Demon choose? 

1/ Iruma . [ Human ]

2/ Aarimon . [ Demon ruler ]
