How can you tell a first printing of Vampire Hunter D?
Vampire Hunter D collecting runs on edition literacy, because the same Amano cover art has dressed at least three Japanese lives of these books. The good news: the editions identify themselves plainly once you know where to look, and the first volume is the easiest of all. A true first edition of Vampire Hunter "D" is the Sonorama Bunko paperback of 31 January 1983, ISBN 4-257-76225-X, Amano's horseman under the Bunko band.
The trap is the reprint. When Asahi Shimbun Publishing reissued the whole catalogue as Sonorama Selection in December 2007 and January 2008, the art stayed Amano but the books changed: Selection ISBNs sit in the 4-02-265 block (volume 1 is 4-02-265500-3) against the Bunko originals' 4-257-76 block. Check the colophon before you pay for age.
