And the manga is so cool! I have the already and I love the artwork in them. The relationship between father and son is sad too I can honestly tell you the manga is better than the anime.
The Australian editions are alright, but are known for not having a very good book margins, and are also known to fall apart after some time. In short, not the greatest quality and something that I would personally pass off.
Here's hoping an American publisher one day licenses it... but that's almost near impossible. I'd rather have something more local and of better quality.
