The story is similar to the plot of most Isekai anime. The main character is transported to another world and has to help it's inhabitants. However, this is a hentai (and a very short one at that), so the story is mostly religated to the back seat. I found the story to be fine, some effort was put into it, but it ultimately didn't hold my interest or attention.
The art/animation is pretty good. The characters have smooth and consistent designs, the backdrops are colorful, and the movement is decent. Some of the characters have unbelievable proportions (I.e massive breasts), and others like the main character have bland and empty designs (no eyes). But the art is mostly good, which is to be expected from studio T-Rex.
I don't have much to say about the sound. I'm not a native Japanese speaker, so I can't judge the quality of the voice acting. The other aspects of the audio are fine, and I liked the end credits song.
The characters are really bland. They don't have many defining personality traits or goals. Besides the main character (lets simply call him generic hero) the rest of the characters are divided into two groups, the elves and the dark elves. They don't like each other but as far as I can tell they share the same goal, save their world and make more elves. I guess the regular elves are friendlier and the dark elves are more "tsundere". It doesn't really matter though since both sides are equally generic.
I didn't get much enjoyment out of this OVA series, sadly. But on the bright side each episode is only 16 minutes! Perhaps I went into this with high expectations? The way I heard this described I was under the impression this was going to be funny and creative, which it certainly isn't. 5.5/10
But overall would I recommend this? Well, if you're a fan of studio T-Rex you might enjoy this, it looks like their other shows, but I'd say it's certainly not their best work. Are you a fantasy fanatic who loves elves? If you're starved for content this might be for you, but if you're looking for something good you might want to pass. This isn't a bad hentai and I wouldn't dissuade people from watching it, however, there're plenty of other series out there more deserving of attention than this one.
2021 Edit: This review was written before it was announced that this OVA series would be picked up for two more episodes. Having seen the new episodes, I stand by most of what I said about episodes 1-2, since they still apply to episodes 3-4. However, I do want to commend the studio for the improved visuals in the new episodes. And I have bumped the score up from 5 to 5.5 as a result.
