I might not have to be so harsh with it, because it's a simple OVA, but here we go. It will be quick and painless.
By the way, it can't be called a sequel because it has nothing to do with the series.
Do you want to see all your favourite characters from Isuca in bikini/swimsuit/half-nude in an island that no one knows why they went to? Then this OVA is for you. Oh, also there's some mistery arround that island but it leads to nothing in the end, you'll see. So it's just harem in a beach.
It's the same style as the original series.
I don't find it a masterpiece nor horrifying.
Well, there's no much sound to play in this OVA. And the few things that were played were plain. Not a OST to enjoy to.
Well, character personalities are intact. But as you might imagine, no development.
I went to do other things while playing this OVA because of the overstanding enjoyment I had. Being serious, you won't enjoy this unless you do love beach and harem episodes.
Do not waste 20 minutes of your life, just try to watch anything else. Or you can watch it while doing some other things, you wouldn't waste your time so much in that case
