Tales of a past life (Goku Black & OC)

"I usually am not this rude towards newcomers, but your sins are so grave, that the mere sight of you makes me sick. Let's not prolonge this any further. I hereby sentence you to Hell."
The tall man said this while putting a stamp on a document, and then he called for the next soul to recieve their judgment.
He was still looking at the woman as her face darkened when she heard the sentence. Before he was tossed out of the line by the creatures holding him still, he heard a voice, a soft whisper, echoing in his mind, that said:

"I'll try to get you out as soon as i can, Zamasu."

Afterwards, he lost consciousness.

An account of the destruction of Black and Zamasu, told from Black's point of view, and what happened next, along with a character of my own creation.

Basically as a "What If?" and an AU combined.
