Well if we're going by in-game rules...actually, I forget if you can fuse Messians/Gaeans in 1, but you can in 2 and that's close enough.
Anyways you get a random result when fusing a human. I think the resulting demon's alignment can't be the opposite of the human's, but otherwise random.
So basically you're just playing the demon roulette when fusing.
https://megamitensei.fandom.com/wiki/Special:Random Judge for yourself if there's an alignment that you could never be I guess, and roll until you get a demon.
