First release of Anthology!
Getter Robo Anthology: The Final Ten Seconds of Space
This chapter is by Eiichi Shimizu and Tomohiro Shimoguchi, creators of the Linebarrels of Iron manga.
Releases for Anthology will be sporadic due to C-K's busy schedule, but since no chapters are related to each other, it shouldn't be that big of a deal.
Still working on finishing up Mazinger Z volume 3, and I've gotten the translation for Getter Robo volume 2 chapter 1.
