Manga or anime? Both are vastly different but both very good. As usual, the manga is darker and really goes into a lot of stuff they had to cut out of the anime. There's also the Read or Dream manga, dealing with the Paper Sisters rather than just Yomiko. The OAV is three episodes of Yomiko and the anime is more centered around the sisters. I can't really fully describe how fun this series is to watch/read, go see it for yourself, fellow anon.
