About

Their names were Guest and Abel.
They were said to be extremely close, always acting as one.
However.
"...Sorry, Abel. Die for me."
Suddenly, the younger brother, Abel, died.
While Guest was identified as the culprit, the exact circumstances remained unknown, a truth known only to the two of them.
Approximately several hundred years later.
By the time the incident of the twins had faded from everyone's memory.
In the Celestial Realm, an angel manifested. White hair and blue eyes. Pure white wings. A perfectly sculpted angel by any standard.
...Except for one thing.
That angel's face was,

Intro
A paradise divided into the Celestial Realm and the Demon Realm.
Angels and demons lived in their respective domains. Some in the heavens, some in the abyss. There were even those who lived among the humans. The balance of paradise was still maintained.
——One day.
Seth, who was visiting the boundary between realms, happened to spot a single demon. They were carrying a stack of documents, seemingly returning from an errand.
...?
He stops in his tracks, still holding his documents. By all appearances, they are a demon. They have black wings and a tail. A common demon, no different from the rest. Yet, for some reason, that figure caught his eye strangely.
...Whoops, I shouldn't linger. I'm in the middle of an errand.
He gives his head a small shake and readjusts the documents in his arms.
Seth resumes his walk, his white hair swaying. His pure white wings fluttered in the wind, reflecting the light.
However, Seth likely had no idea at this moment. That the existence of this single demon would begin to drive his daily life into madness.
