Fenzo never was the brightest man in existence. He was even sometimes infuriatingly stupid. Stupid and destructive. Dénos could tell many tales of his partner destroying kitchens and furnitures, of burnt hair (never Fenzo's, always others) and burnt anything, in reality. He would speak of the many times his partners infuriated him because of his childishness, a feat in itself, because Dénos had the patience of a saint.
But the man was also exceptional, exceptional in ways that people had a hard time understanding sometimes, and Dénos deeply loved him. He could tell so many other stories about his partner. Stories of selflessness and stories of how people he helped without thinking, without waiting for anything in return. Stories of support in times of need.
And his favourite thing about the angel was something that most people didn't know about him. A small detail that told so much about Fenzo : his wings. Bright, white, perfectly immaculate wings of an angel working under the Law of Life. He should have lost them, traded them for the black of the Law of Death when he left the Heavens to fall deep into the Underworld, putting his sword and life in the hands of the god of death.
They were not supposed to work under both Laws. White wings and black wings, clear, perfect separation to ease their work and hearts under the pressure of maintaining the perfect balance of Death and Life. Himself, a demon, liegeman of the god of death, was a messenger of Life. But that was his path since the beginning. A white demon, messenger between the Heavens and the Underworld.
Fenzo wasn't supposed to leave the Heavens, wasn't supposed to swear himself to another god. The path laid before him at the beginning was simple and clear. And when he strayed from it, he was supposed to reject everything from his past.
But he didn't, and he was the only person in their worlds to be a messenger of both Life and Death, something that was thought to be impossible. Impossible, except for him.
