While I certainly won't deny that both of them are cute, I can't help but feel like the salamander and undine elements are sorely lacking in these two girls. One has nothing but little horns and the other one might as well just be an elf. Surely the artist could at least add some scales, or fluid hair, something to make them more inhuman?
At least bikini armor pole-dancing is quite a unique scenario.
I wonder how many people caught from the bonus that its not the same guy each chapter. Its a multiverse of Otaku-kuns out there and each one has a unique set of fetishes.
You know, I feel like it works as "if you have every fetish, you have no fetish" kinda way.
So the ultimate goal of this story is to make Otaku-kun a "normal" guy
