Here's God Mazinger in its entirety. It's pretty good, so I would recommend it. However, the art isn't 100% Nagai as anyone would be able to tell from how it looks. To me, it looks more like an Ishikawa manga or something from one of Dynamic's assistants. Possibly Nagai more wrote this one and did some of the drawing than his usual manga. Well, at any rate, the volume edition does change after volume 01 so that's why there isn't a volume 02. Volume 01 is from a reprint IIRC which had 01 & 02 in one volume. That said, do enjoy.
