During an airplane test, Daigo and Reina's son, Tsubasa, returned to ancient times and was rescued by a group of villagers. Duguma, Dadana, and Myron, who attempted to dominate the darkness, manipulated the monster Zomondo to launch a plan to attack the village. Tsubasa and the villagers prepared to fight against the invasion of the monsters... Next to the villagers who were defending one-sidedly, a traveling warrior, Maba, appeared. The bronze Sparklance he held made Tsubasa feel very familiar. He thought it was the Sparklance that made his father Daigo transform into a giant. When he picked it up and concentrated his mind, he turned into Superman Tiga! But he was short and had no energy, so he couldn't defeat the monsters, and he quickly turned back into a human due to insufficient energy. The dark demon Duguhu finally woke up and attacked the village with the monsters... Could it be that Tsubasa is not the descendant of the Giant of Light? Then who is the real descendant? Can the Giant of Light finally be resurrected...
