A brand new Nagai project here! A short one, and a crossover of Grendizer, Mazinger, Koutetsu Jeeg and Getter Robo for maximum awesomeness, just like the games. As usual, we owe a lot to Hokuto No Gun and Dynamic Pro. Please consider donating to Dynamic Pro to ease the burden from the raws and translation fees as well,and we're still interested in help from new editors and translators. We've got other Nagai projects, Kazuo Umezu, Shotaro Ishinomori, Osamu Tezuka, the ninja manga Azumi...all the classics. Any help will make things go a LOT quicker,too!
