When Kaito Yukimura dies in a blaze of betrayal, he expects darkness. Instead, he wakes in the underworld—chosen by the Devil’s System, a sentient power that offers him a second chance… at a cost.

Reborn as a Contractor, Kaito enters a brutal realm where the strong carve their names into history and the weak are devoured. With a blade forged from shadowflame and a system that feeds on his rage, Kaito rises fast—but something inside him is changing. The more he fights, the hungrier the system becomes.

Haunted by the past, hunted by a forgotten enemy, and burdened with powers that threaten to consume him, Kaito must decide: will he conquer the system, or become its next devil?

In a world of blood, betrayal, and broken gods…
Redemption has a body count.

Reborn with the Devil’s System

The fire portal twisted reality as Kaito stepped through it, like walking through liquid flame. He braced for heat—but instead, a chilling breeze welcomed him on the other side.

He emerged into what looked like a massive obsidian arena, surrounded by jagged mountains under a blood-red sky. Black banners bearing strange runes flapped in a wind that carried whispers.

At least a dozen others stood in the center of the arena. Some looked dazed, others calm, a few outright hostile. Each had the same eerie red glow in their eyes—just like Kaito.

Bael's voice echoed across the arena.

"Welcome, Contractors. You've all made your pacts. Some for vengeance, some for power, some... just for fun. I don't care why. What matters now is what you do with the system I've gifted you."

A system prompt appeared before Kaito's eyes.

A tall girl with silver hair and a long crimson scarf stepped forward. Her arms were folded, her gaze sharp.

"Is this going to be one of those 'survive to the top' bloodbath games?" she asked dryly.

Bael grinned. "Eventually. But for now, consider this orientation. You'll be trained, tested, and upgraded. The Mortal Realm isn't ready for you yet. You'll tear it apart too early."

Kaito glanced around at the others. A bulky guy with a jagged axe. A quiet boy in a hood, who hadn't stopped muttering to himself. A woman with sharp claws instead of hands. They were all... off. Dangerous.

But then he caught a pair of eyes watching him from across the group.

A dark-haired man with a scar over one eye. His system interface shimmered faintly—he was hiding it. Skilled. Experienced.

Kaito's eyes narrowed. Renji Kuroda.

One of the people who betrayed him in his past life.

Renji tilted his head, a faint smile tugging at his lips. He didn't recognize Kaito—yet.

And when the time comes... settle old scores.

He wasn't just reborn for revenge.
