This is listed as a special and I don't know what the difference is between it and an OVA really I guess besides how they're packaged with something, but as extra little episodes these are pretty good for what they are. Some OVAs feel like there is some simple idea that was basically already in the show that can be put together, and maybe that's as true for these little episodes, but they are enjoyable and actually funny in a few of them. It's almost like a good preview for the entire series because its short and lets you get a good idea of whatthe series is about.
