“You betrayed me in my first life… Now you kneel in my second.”

Ryouma Kazuki died a joke.

Betrayed. Forgotten. Used.

But death was only his beginning.

Reincarnated as Lucius Nachtveil, the final boss of a cursed fantasy world, he wakes up with power beyond logic—and a fate written in blood. Feared by all. Loved by none. Or so he thought...

Because something is wrong with this world.

The heroines who once betrayed him? Now obsessed with him.
The heroes who should slay him? Losing to him.
The gods who cursed him? Watching in silence.

His body is cursed. His heart is fractured. And his power grows the more he’s hated.

Yet no matter how cruel, cold, or chaotic he becomes...

They. Can’t. Leave. Him. Alone.

From yandere elf assassins to holy angels corrupted by lust, Lucius is surrounded by a harem he never wanted—and a destiny he refuses to follow.

But he’ll play their game.

He’ll become the villain. The tyrant. The monster.

And when the world begs for salvation...
They’ll find that only the devil can save them.

"Reincarnated as the Final Boss, But the Girls Won’t Let Me Die!"

Velda stood by the wall now, arms crossed, cloak slightly soaked from the steam, her gaze locked on Lucius.

"You've been reborn into the final timeline," she said. "There are no retries. No do-overs. The Chosen Heroes have already been summoned."

Lucius didn't flinch. "Who are they?"

Velda raised a hand. Three glowing sigils appeared in the air:

She tapped the last one. "That one… belongs to your brother."

A hospital room. Faint beeping. Lucius—then Ryouma—sat at the foot of the bed. Takeshi stood at the window, looking down at the snow.

"You always ran from everything," Takeshi muttered. "School, work, mom's funeral... even her."

Ryouma's hands clenched. "You don't know what I've been through."

"I know exactly what you've been through," Takeshi snapped. "You just always wanted to be the victim."

Then Takeshi turned, his eyes cold. "If I ever had your power… I'd change everything."

Takeshi was standing above him in the game world. Sword drawn. Betrayal fresh.

"I should've been the one they summoned," he had said.

Claire looked at him nervously. "Lucius…?"

"I need a sword," he muttered. "Now."

Meanwhile, in the floating capital of Aerendel…

Takeshi Nachtveil stood at the edge of a balcony, his white armor glowing with holy runes.

A priestess approached from behind. "Lord Chosen, the Demonblood Tyrant has awakened."

He looked at his hand—still stained with faint traces of blood only he could see.

"Tell the others. I'll end him again."

The priestess hesitated. "But sir… he's your brother."

"No. My brother died the moment he let the world destroy him. What's walking now… is a monster."
