Story: 4/10
Biologist goes on a journey to study horny female elves and does exactly that. There really isn't a story here. He just meets elves and fucks them. Most people probably don't care, but I personally found this boring to watch. There weren't any fun/wacky moments that other hentai's have that make it worth watching for anything other than sexy hot anime girls.
Sound: 8/10
The template I use for reviewing hentai is an old template mal use to use for reviewing anime in general.... idk wtf I'm supposed to be saying about the sound design of a hentai. Uhhhh, voice acting was there, hentai noises was there, uhhhh, it does the job.
Art: 9/10
Animated by the ufotable of hentai, Bunnywalker, a company that may or may not exist since the only mention of it comes from hentai websites. Mal doesn't acknowledge their existence. Anyways, if a hentai is associated with the word, "Bunnywalker", you know you about to see some good shit.
Characters: 5/10
Just hot elf girls. Nothing really distinguishes them for each other besides slight differences in their personality... Oh wait, some have inverted nipples if that counts.
Enjoyment: 6/10
It's a fine and well-animated hentai. But it's lack of a fun story and distinct waifus makes it quite boring to watch aside from the sex scenes. I realize now that I'm sitting here complaining about the plot of a hentai, just watch it if you want to see hot anime elves having sex or don't watch it if you want more than just hot anime elves having sex.
Overall: 6/10
