I have started reading Tsubasa from our local library, which unfortunately does not have a very expansive manga section, and so they only own the first three manga in the series. I'm currently searching other places for the next books in the series. Also, I've started reading Negima! Magister Negi Magi and am quite enjoying it. Once again, our library only has the first three in the series.
New Zealand doesn't have as much of a care for manga as other countries...
