First pressing comes with a small informational booklet. It contains interviews, illustrations, etc.
Now, some people may be wondering why I canceled the preorder for the future volumes of this series. It's because I don't care for this type of anime. I read rave reviews about the show, so I decided to try it out. It's a specific type of shoujo manga that walks the fine line between like and hate. Imagine "Koko wa Greenwood," but take out all the shounen components from it. In general, I don't care much for either extremes. In fact, I believe that it's the shounen components that kept Greenwood from going stale. Both shows have quirky characters, but in Greenwood, it was the minor component. In Hachimitsu and Clover, it seems to be in the driver's seat. The romance component is never taken seriously in Greenwood (good), but here, it's the on-going sub-theme.
Anyhow, I don't like it and I know I don't, so I'm not going to watch any more of it. Thankfully, this was relatively cheap.
Oh, just in case anyone is wondering, I don't think there's any problem with the animation quality.
Making of the OP (one of the bonus clips). They must have spend more time and effort into making the opening sequence than making an actual episode! It's pretty interesting, though.
