Duke Fleed's story continues in this long-awaited sequel to the seminal Mazinger Mecha franchise. The war between the forces of Vega and Grendizer is but a distant memory. But from the confines of space, the Ruin Division emerges with the most powerful Saucer Beast: the Hydragon. Under siege, pilot Duke Fleed has no choice but to join the fight and reawaken the Mighty Robot Grendizer, or risk the world he once fought so hard to protect.
