Story: It's basically about an alien trying to conquer the earth by yurifying it. Not much else happens this this is an ova, but if you really wanted to get the whole thing I'd definitely recommend the manga.
Art: The animation is amazing, with maximum efficiency and minimal frames, from the brilliantly talented Tetsuya Takeuchi. You probably don't know, but his animation style usually fits into that category. The art is light and colourful, maintaining quality all throughout both ova's running time.
Sound: The show has a very retro feel to it, one that you would find on some of the old arcade machines and early 90's home consoles. Overall it's pretty enjoyable.
Character: Because this show is so short, there isn't room for much character development at all, but you get the idea that Naoko is trying yurify everything, with Misuzu disapproving of everything like a regular person would. But of course there isn't much room for character development, so once again I heavily recommend the manga.
Enjoyment: There were some pretty good moments all throughout the entire show, you'd think the entire thing would just be filled with lewd joke after lewd joke, which it is. However they are pretty funny throughout both ovas.
Overall: You can definitely tell Tetsuya Takeuchi cared about this, you can tell that he actually read the entire manga to get a feel of the characters and how they would react. And I definitely hope he gets more opportunities to show off his talent because I'd certainly watch whatever he makes.
8/10 They really need to make more of this
