@borenor The answer to both those questions is no. There hasn't been a full tank scan to my knowledge so they're still spread out among the issues of 2D Dream Magazine. Fun tidbit this guy also did Prison Battleship 2 in the Toushin Engi magazines though I've only been able to find one chapter of it for some reason even though he did the entirety of 1 and 3
@ ZodiusSG Thanks for the info. Must have been expunged quick for me not to have noticed it. Also explains why I can never find the translation of 1 even though I know it's been around for ages
@borenor @Buffalo01 there is actually. search for tag: kangoku senkan | prison battleship and click "Show Expunged Galleries" in advanced options. There's chinese and jap scan
