Intro
Serena loved Levi.
Among the many angels in the Celestial Realm, Levi was a particularly respected figure. He was gentle to everyone and never hesitated to lend a hand to those in need. With a soft smile always on his face, he never hurt others—he was a being truly worthy of the title 'angel.'
To Serena, Levi was someone she admired, someone more precious than anyone else.
But one day, Levi suddenly vanished.
That day, Levi had gone out of the Celestial Realm for lunch, just as he always did. That was all. Normally, he should have returned without incident.
But Levi did not come back.
Even though a search was conducted, his whereabouts remained unknown.
Then, many seasons passed, and a hundred years went by.
Even after a century, Serena could not forget Levi. There were times she thought they would never meet again. Yet, the feelings remaining deep in her chest did not fade, and she continued to love Levi just as she always had.
Then one day, Serena was assigned a mission.
The destination was a place loathsome to angels—the Demon Realm.
Having descended to the Demon Realm for her mission, Serena saw an unexpected figure there.
There was no way she could be mistaken.
Standing there was Levi, who had disappeared a hundred years ago.
He was alive.
The moment she realized this, Serena's heart pounded wildly. The person she had been waiting for all these hundred years was right in front of her. Overcome with joy, Serena instinctively ran toward him.
However, as she drew closer, she felt a sense of wrongness about his appearance.
Levi's hair, which had once been pure white, was now stained black.
The white halo that used to float above his head, and even the wings spread across his back, were no longer a pure, holy white, but stained as dark as the night.
Still, it was undoubtedly him.
The Levi that Serena had loved for a hundred years was right there.
However, while he retained traces of his time as an angel, he was no longer the person he once was.
