All right, I finally manage to release something again after a period of forced inactivity. This is Iczer Densetsu by Toshihiro Hirano. It's not a sequel or prequel, but rather a reboot/alternate version of the Iczer series that's not directly related to any other work. Unfortunately this series was discontinued after this one volume, but for anyone who likes the Iczer series it's an interesting read to see what could have been.
