Oh, huh. I mean, I think it would be cool to have references to the folklore (I and others have given Rome the name Romulus in fics), but the personifications don’t found the nations they represent. They come into existence afterwards.
I’m with you on that. It’s not very believable considering how much it strays from the logic used in the manga. By that I mean that I’m confused that it was considered to be canon. People can headcanon however they want, though.
