The second-to-last chapter is here! I had it posted it up yesterday, but blogspot was down.
Getter Robo Saga - Shin Getter Robo Chapter 8 (of 9)
The final chapter will be out next week! It features an altered ending, so be sure to check it out. I'll be taking down all links to the old Shin Getter Robo scanlation once I'm done with this new version due to irrelevance.
