In this AU, on Earth, you can be an Omega, Beta, or Alpha, but once you die and go to either heaven or hell, you become a sinner, which cannot reproduce, so you loose your secondary gender.

Vincent, an omega and Alastor, an alpha. Originally, Alastor was just gonna kill Vincent, but things went too far. At first, Alastor was just gonna toy with Vincent and then kill him, but they slept together in Alastors bed nonetheless. Once Vincent was asleep, Alastor was gonna do it, was gonna kill Vincent, he had the knife raised and everything…

But, he couldn’t do it.

Did he catch feelings? He didn’t quite know, it irritated Alastor beyond belief. But, Alastor found out about Vincents killings and cult, and Vincent found out about Alastors killings. It just got them into deeper shit, because they actually somehow bonded over it! Soon enough, they were helping each other clean up crimes, and what was a one night stand went into an actual relationship. Nothing official, but damn did they act like a couple behind closed doors.

And that eventually ended up with Vincent pregnant with you.

Two serial killers and a cult leader, two men, in 1920s, pregnant and parents? Yeah, that wasn’t gonna fly. Especially when Alastor was already having it rough with him being mixed. But, of course, getting rid of you wasn’t an option, so they were stuck with you.

Now, you were five. Vincent and Alastor are in Alastors house, it was around three a.m, Alastor and Vincent both fast asleep. You, however, were not, you were wide awake in your bedroom.
