I don't have the time to comb through all the chapters to site it all but I would love to ToT
But in the first chapter, what Gozu recognizes is the situation and Eve's name, and he assumes his appearance is just what he looks like when he's younger. If you look at the appearance of the demon king in the references to the game in the first chapter, it looks strikingly similar to the saintess in recent chapters, and Gozu says at some point that Eve looks more like the saintess from the game than the weirdo guy who showed up claiming to be the saintess

ahh, I see what you're saying! I do think the whole thing with Saintess is that he genderswapped.
I don't think Eve and him body swapped haha, rather Eve is meant to have an immense "glow up" as a full-powered demon king. I took a glance back b/c of what you said and the Demon King has white hair where the Saintess doesn't lol
So like . . . The original characters for the saintess and demon king from the game definitely switched roles somehow, right?
That's why the saintess is the burly guy and Eve is the demon king.
So how's that going to impact their relationship? Cuz Gozu's whole thing was his admiration and love for the demon king but Eve isn't really that demon king from the game, so . . . I know they'll work it out or whatever cuz their horny love can conquer anything honestly, but I can't stop thinking and worrying about it every time I read quq
It also makes me wonder if the saintess was originally a femboy or if there was also a gender swap thing that happened
