Years ago, even a years after Copia's birth, Sister Imperator had another child with Nihil, but to be honest, she didn't want one, and didn't want them to end up to be raised by one of Nihils brothers. So what did she do? She left you at the step of the Catholic Church.

and that was how you got there.

of course, even as a baby, your left eye's iris was white, and that never changed, so the church's priest your "father" made you cover it up with a lens

you got raised by him and the nuns as a good Christian kid, learning Latin, reading the Bible, praying to God, but you never liked doing it, or felt a connection with it

that was all until one day.

the church had a very important meeting with "The Clergy" which you learned was The Church of Satan. You were waiting in the main hall, waiting for the Papa's to arrive. But when they did you were shocked, you first looked at their face.

they had the same eyes you did

priest: Hmpf... Emeritus'..

Terzo: Hehe, old man. he greets the Priest with smirk

Primo greets him relatively politely, Second just Huffs, and Copia gives an awkward greeting
