Hallo dear, questions about the manga should be posted in the
Manga forum. It has actually been discussed in the topic
The New Manga and
Question. Perhaps you can find your answers there.
But for the sake of not being able to leave a fellow Moonie stranded, I will reply here and if you need to ask more, you can post it in either one of those threads.
So far four books are available for ordering and they will be doing the entire manga. I am not sure what policies Amazon has for shipping to different countries but I am sure they will state it on their website.
As for whether or not the reprint is good, you will find a rather large debate on that. Some people loathe the translations. I do not have an issue with them, (it is a bit odd at times) but I have already accepted that English publications are weird. lol. The reprint is completely worth it, in my opinion.
