In a devastated 1995, Earth lies under the iron grip of the Akron, an invading force that has reduced civilization to scattered refugee camps and crumbling towns. Kento, a young orphan hiding in the wilderness with his friends, stumbles upon something extraordinary: the secret laboratory of Dr. Earl, a fugitive scientist from the conquered planet Helios. Dr. Earl carries with him humanity's last hope: Daltanious, a revolutionary super robot built with Helian technology. But the machine's true power emerges only when paired with Beralios, an intelligent lion-form mecha that responds to a specific bloodline. To Dr. Earl's shock, Kento carries that bloodline in his veins, making him the key to Earth's resistance against impossible odds. What begins as a chance encounter becomes a war for survival. Kento must master piloting Daltanious while navigating the chaos of a conquered world, armed with alien technology and the weight of two planets' fates resting on his shoulders. Explosions, comedy, and giant robot battles collide as an unlikely hero learns what it means to fight for freedom.
