For me, the artwork is by far the most important for hentai. A bad story can make it bad, but even then, it can be quite fappable if you ignore the story. A good story can also make up for mediocre artwork to an extent (good situations can be huge turn ons for instance, even if the artwork is subpar), but it still suffers big time. And much as I prefer great stories, I find that (for me at least) great artwork with mediocre stories is _way_ better than great stories with okay artwork. Of course, what we really want is great stories with great artwork, but you can't always have it all.
Interesting honestly, wasn't a bad story. Could have probably done without the whole group thing, but otherwise refreshing in it's own way. I'm also a fan of Katase Minami's art style
...Is this what happens when you're like on the verge of death? The crow you just so happened to save says you gotta have group sex and bathe in their sperm in order to live again? I suppose at least it's just...mentally, and not really physically, or something?
I'd probably have liked it more if it was just him without the group aspect, but hey, it was rather interesting.
