The story in this is actually quite good for a hentai as backstories are explained and characters are developed to give this world some life. It's an interesting mix of sci-fi and medieval monster killing that seems to focus on an elf (with no pointy ears for some reason) and her desire to protect her home village. It's also fairly wholesome as the only sex scene is consensual sex between the main characters who love each other.
The art is pretty good for the most part and the girls are well drawn and look pretty sexy, and the animation is well done for the majority of the episode. The one hiccup in the animation is randomly during the sex scene it seems to go into a weird hyper mode were everything suddenly jumps up in speed and looks a bit goofy. This seems to be a director's choice though as nowhere else does it do this and the sex scene is only maybe 5-7 minutes of the 30 minute run time.
Now the part it stumbles up a bit on is the enjoyment. Their is only one sex scene in the entire episode and it only consists of one girl despite the trailer advertising two girls and the tan girl clearly is made to be heavily involved later on at some point. Then the sex scene itself is definitely not going to be for many people as the girl is a futanari (only revealed at the sex scene) and has the boy giving her oral which is a miss for most people. There is also the odd choice of showing instant orgasm after instant orgasm with no play or much sex in between, which just comes off as a bit annoying as it kind of feels like deja vu and the girl moans exactly the same way over and over making it a little annoying. However, the biggest miss for myself and probably most people viewing this is when he sucks out his own cum from inside her. I have no idea why they thought that would be something people would want to see and instantly kills the sex scene at that moment.
Overall it was a pretty good hentai, despite its one glaring moment, and a lot of people could enjoy it for the story and most of the art and sex. However, I wouldn't recommend it to anyone. It doesn't really do enough story or sex wise to make it stand above other hentai with similar qualities and that moment is a big enough turn off I couldn't recommend that to be seen by someone else (unless you're into drinking your own cum). If they removed that and added a sex scene with the tan girl this could have been a 9/10
