I've really enjoyed this manga and would really like to support the author by buying the official books but as far as I can tell it's only been printed in French (other than the original language).

So I was wondering if anyone knows if it is possible to buy it in English?

There is a section on the series page, which states whether the title is licensed in English or not.

It's not available in English. :-( I wish it was though! If it was I'd buy all the volumes too. I guess we'll just have to keep an eye on it. 😃
