[ENG DUB] The Last Guardian of a Doomed Humanity

After sacrificing his life force to protect humanity in an underground bunker for 30 years, Alan Clifford is betrayed. His adopted daughter Cindy and her ally Chelsea fabricate evidence, frame him, and turn the populace against him. Condemned to death, he watches as the people he saved destroy their only sanctuary and rush to the surface. There, they fall into a deadly trap laid by giants. As the slaughter begins, Alan—now a master of powerful mecha technology—faces a final, agonizing choice: should he save the very humanity that condemned him?
