Here's also a batch torrent to the whole series, if somebody wants:
All 13 eps batch - CrystalNova
Needless to say, this series was unique. It contained close to zero action, zero fanservice, trace amounts of romance, little to no dangerous situations... You get the picture. What it did contain was a strange warm feeling. Aria had lots of really good characters, and that was the point of the whole series. It's simply amazing how well the show worked with the few basic elements it was solely relying on.
