Premise
The story's theme is based on stories in Greek mythology, especially those surrounding Heracles, upon whom the main character is based, and his Twelve Labors. Many of the other characters are also based on Greek mythological figures; characters share similar names to their Greek counterparts, and how their relationship is defined with others correspond with Greek stories. The title of the series, Heroic Age, is also a slight testament to the similarities to Greek mythology, referring to the time of the Heroic Age. The tribes featured in the anime are loosely based on Hesiod's Five Ages of Mankind.
Storyline
The show is set in a futuristic universe, controlled by a few races or "tribes" that possess the capabilities for interstellar travel. The universe had once been ruled by a "Golden Tribe" (黄金の種族 Ougon no Shuzoku), who had since left the current galaxy long ago; they passed on their knowledge to the humanoid , the insectoid , and the gigantic . The latter was later punished by the Golden Tribe for causing havoc in the universe and made to serve the other tribes as - extremely powerful beings that play a key role in the story. Before the Golden Tribe departed, Humanity answered the call of the Golden Tribe and was dubbed the . Viewed as a threat to the order of things, the Silver Tribe decided to annihilate the Iron Tribe with the aid of the Bronze Tribe. However, humanity survived their assault on Earth and scattered their numbers across the stars in order to preserve their race.
The story follows the voyages of the starship Argonaut and its crew to find a means to bring peace to the universe. The ship carries the young human clairvoyant princess Dhianeila, who is on a mission to find the mythical savior of the human race. This savior is expected to aid humanity in their war against the Silver and Bronze tribes, who are bent on humanity's extermination.
Initially, the expedition finds a child-hearted boy called Age on a partially destroyed planet. When the Argonaut is attacked by the Bronze tribe, Age is shown to transform into a "Nodos" form, Bellcross, a gigantic and immensely powerful being. He easily fends off the superior attacking force. Having found their messiah, the Argonaut starts its way back to Dhianeila's home-world, Duey. During their journey home, the Silver Tribe launches several attacks on the Argonaut to prevent the ship from returning to their home-world, but Age always managed to stop them.
During the many attacks on the Argonaut the crew begins to warm up to Age, they had been fearful of his powers as a Nodos. The Silver tribesman Phaetho O assigns himself the role of "testing" Age, destroying the Argonaut and all the Iron Tribe on it. After Age drives Phaetho O away and saves his tribe they all begin to accept him. Iolaous Oz Mehelim of the Yunos knights is jealous of Age but warms up to him after the attack on Titarros. Once they escape the battle against Phaetho O at Titarros the Argonaut crew arrives near the Cemetery belt where they are again attacked by Phaetho O and the Bronze Tribe accompanying him, here Age fights another Nodos whom had visited him on Titarros. During the fight the Argonaut manages to escape however in order to do so Age had to stay behind to fight. The Argonaut warps to what they think is an unoccupied place and end up running into stragglers from the Bronze Tribe, rather than fight they attempt to run only to be cornered by an enormous fleet. the fleet is also Iron Tribe, after saving the Argonaut that fleet accompanies them and they leave to help Age.
