Because there is no CH Manga volume.11 in Germany :cry:

I would like to ask about the CH US Mangas (Englisch Language) on Amazon.de (Germany) you can buy for 9,94 Euro Volume 1,2,3,4,5 but I don't know whether the Mangas are cut or zensiert (Censorship)
The German CH Mangas 1-10 are only for adults (adult = 18 Years) in the German shops
