The OVA from the Ah! My Goddess series. This OVA is obviously old but still very good.
Story: The first three episodes are pretty much the same as the beginning of the 2005 series with a few minor differences. After that the story takes on it's on twist of the series. The ending is rather confusing and I had no idea what was happening exactly.
Art:
Obivously older. The art is definitely not as good as the 2005 series, but I guess it's not the worst art in the world. The animation also was not up to my standards, but it was still decent enough to watch.
Sound: The opening and ending themes were nice to listen to, but not amazing. I don't remember if there was background music, but if there was it was unmemorable. The voice cast did an excellent job though :)
Character: Likeable, but not very developed as it is only a 5 episode series. You don't really get a full feel of the character unless you've previously seen Ah! My Goddess.
Enjoyment: Kinda bored. 30 minutes each per episode can kinda be boring. But all in all I liked it.
Overall: The story was very good. The art could've used some work and so could the sound. This series should've been made into a longer OVA so that the characters could be developed further as this anime is all about the characters. But I still really enjoyed this.
