kingofhearts delivers awesome mecha once again. (hums) "Hitosuji no raikou ni tera-sarete, koutetsu no ban'nin ga sobie-tatsu..."
Shin Mazinger ZERO by Nagai Gou, Tabata Yoshiaki & Yogo Yuuki, 9/9 volumes, complete.
I saw someone sharing the volumes 5-8 but here is the full set. I didn¨t use the volume format for 5-8 because scanlators uploaded those chap by chap, and there is even one v2.
As an omake, I threw in a zip file for complete VS Ankoku Dai-shougun, sequel, all 36 chapters (8 volumes), Japanese RAW, no English scans exist. For some reason, I can't open that zip by Windows' own program, but it can be opened by 7z. I think the filenames too long or something... anyways, enjoy!
