Never would have expected them to defeat the monster by giving it an Orgasm, but this series continues to surprise me.
It was surprising, but it also fits well with the kind of word play that you often find in myths and folk tales. I quite liked it.
I'm less fond of how an attack that was implied to be a rape attempt (or analogous to one) was just sort of brushed off, without anger, fear, or any kind of negative consequence. I'm not sure if the story is downplaying the seriousness of what happened, because acknowledging it wouldn't fit the tone, or if it's supposed to imply something about how Naori thinks about herself. It honestly feels like a bit of both and while the latter could lead the story to some interesting places, if it's explored appropriately, the former would be disappointing.
