I disagree. How does this loli demon tonal shift/continuity breaks from the totally weird (and suspicious) human god, for example? I'd say the problem is that we didn't see that much of the demon continent. We saw Roxy's home village, that one city, and now they are already in a harbour town ready to leave the continent, provided they can secure a ship voyage. The demon continent might have been full of all kinds of strange, esoteric folks, seeing how it has to be the most heterogeneous of all the continents. The demon loli could have been nothing out of ordinary by local standards.
