I"s Pure was recommended to me by a friend. I read the manga during my commute time and watched the anime during my free time. Reading the manga in advance, I was really expecting great things from the ova. The 6 episode ova series was great, but it could have been better. Squeezing all 15 volumes (143 chapters) manga into a 6 episode ova, what would you expect. Some of the good part from the manga, which IMO made the story richer, was left out. Although all the important part were included, the pacing of the series is somewhat fast passed, giving little time tothe audience to fully digest the story and the emotion that it conveys.

Overall, I would say that this is one of the best series out there. There's only few anime series out there that would remain in your memory for a very long time, and I"s Pure is one of them.

It's been a while since this ova series has been released. I hope someone would pick it up and create a full anime series (12 or 24 episodes or more) that is closer to the manga.
