idk if this was mentioned before, but now I think about it more, I think I understand why Hybrids aren't erased from existence even though the concept itself were erased.
1: concepts can come back if they're not something purely axiomatic in nature
2: Hybrids is a combination between a human and most importantly, a Devil's heart
With that we can conclude that even though Hybrids were erased as a concept, the devil and the human were not, and the act of combining the 2 is no different than America reinventing the nuke, Fujimoto did not pull that out of his ass, it was foreshadowed since Part 1.
Alright guys, Hybrids resistances are about to get a big revamp, they're frauded soon enough (or is it Pochita that is gonna get frauded?).
And with this information, Barem getting eaten meaning Flamethrower Devil's heart is gone, meaning that GG to all flamethrowers in the world, they're gone gone.
In a better light, lots of devils gains a slight resistance to conceptual erasure and stuff yay! Maybe?
Wait, now that I think about it, Yoru never remembered about nuke until it was launched and introduced back to the world, iirc Makima still registered them as "erased" meaning that the concept haven't came back yet, but the nuke for sure disappeared, not the hybrids, meaning that I was wrong, it's just that the hybrids are truly special since they are part human AND Devil, Devils who would still exists because their concept are still there, and because Hybrids are one with the Devil, they did not disappear?
Eh, so nothing changes?
