Their alternate universe lives in a post apocalyptic world, though
true
thats true but i havent read that manga in a long time so i dont know which versions are featured in the little easter egg
It's in v 2 ch 4
actually i didnt realize they were a humongous part of the series, i thought they were an easter egg but nah
i rmemeber someone saying they saw sen and amatatsu in the zombie hide sex series the author also works on and them being sad because they would have to live in a traumatic world. However im glad the author decided that they were dimension travelers and they dont actually live in a post apocalyptic world
