Those from "Carlsen Verlag" (german translation, if you wonder) seem to be quite accurate, barring the occasional goofy or wrong translated words.

Though except for the volume cover, everythings grayscale, including the pages that originally were coloured in the magazine. No idea if they had colour in the japanese book releases.
