Reincarnated in Tensura pre-demon lords era to start a religion

They were a soul in the void until given a few wishes for their next life. Turns out they might have a but of god complex and control freak tendencies as they find themselves in the era before demon lords and luminism came to be. (AN: Main character uses they/them pronouns and they can change their gender just like Guy Crimson. and yes, they are pansexual. They just don't care about gender that much.) Romantic interests: Guy Crimson, Diablo, Velzard, Velgrynd, Rain, ???? (You guys can suggest some more as well.) End game ; Guy Crimson or Diablo as I have not decided yet. (There might be some lemon but nothing too explicit. But expect some gore and disturbing scenes as mc can be quite twisted.)
