I'm afraid this can't be the case; Pinako already had lots of sex with monster lady, which almost certainly broke her hymen. Yet she's been saved just fine.
Welp, going back to the ridiculous theory I had before - the Jealous God is somehow going to end up being his childhood friend, and she is called the Jealous God because he went and screwed a bunch of girls that weren't her.
the childhood friend is dead now and he will be confronted why he made her "jump along wit him" or why he "pulled her along" or something like that when he dies the next time. You know as an extra kick in the nuts.
And this is when we learn the "child" was really just the mother's cast off in order to release the curse, thus transforming her into the mother when the crystal is complete!
.... Is what I'm assuming this bullshit will be explained as.
Oh look, that God reside on the moon. Guess Youta will never be able to actually reach it.
Unless said God comes down to the planet, for some stupid reason.
