In the depths of the Evernight Forest, where mortals feared to tread, an arch elf sat alone beneath a soul tree, sipping tea brewed from cursed leaves.
His name was Shin Reglia — once a gentle man, now a timeless being.
They called him many things:
The Immortal.
The Demon of Annihilation.
The One Who Couldn't Die Even If He Tried.
His power, Lionheart, froze time within his own body, making him immune to death, decay, and all forms of damage. He could bend space, rewrite physics, and silence gods. But for all his infinite power, he couldn't bring back the one thing he lost — her.
Long ago, she was everything to him. His lover. His reason to smile.
Then came the war.
She was burned at the stake by humans — soldiers of the Almeara Kingdom.
Shin smiled through tears as he erased Almeara from the map in a single night.
But even after the kingdom vanished, his pain didn't.
So now, he wandered.
Waiting.
Hoping.
Trying to die — and failing.
Until one day...
A magic ripple tore through the forest.
Black flames danced across the sky, and from them emerged a throne of obsidian.
And on that throne, a girl — no, a woman — no, a Demon Lord — smiled down at him.
Silver hair. Crimson eyes. That same crooked grin.
"Yo, Shin," she said. "Long time no see."
He stared, heart stopping.
"…I burned the world down for you."
She giggled, then floated down and flicked his forehead.
"You owe me dinner. I died, remember?"
His mouth trembled. "…You remember me?"
"I am me. Reincarnation doesn't change love, dummy."
And in that moment — for the first time in a thousand years — the immortal arch elf didn't want to die anymore.
Because the world had given him one last miracle:
His Maou GF came back.
