This series is literally the author just cutting all the pretense from dagashi kashi, huh?
"Let's make a new series, where Hotaru is literally a vampire instead of a vampish girl. Also instead of eroticism in innuendo, let's make it *actual* eroticism, it's vampire after all."
But honestly, this series is really fascinating. Honestly my only problem is Nazuna's costume design. I have nothing against bare skin, but Hotaru's goth loli outfit is way hotter than Nazuna's... whatever it is she's wearing. Come on, you're a vampire. What's the point of being a vampire if you're not dressed in some hot goth outfit or some sort of frilly dress. A little black dress at least.
