Heroic Age (ヒロイック・エイジ, Hiroikku Eiji) is a Japanese science fiction mecha space opera[1] anime originally conceptualized by Tow Ubukata.

The show is set in a futuristic universe, controlled by a few races or "tribes" that possess the capabilities for interstellar travel.

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.

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.

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.

The Silver tribesman Phaetho O assigns himself the role of "testing" Age, destroying the Argonaut and all the Iron Tribe on it.

Iolaous Oz Mehelim of the Yunos knights is jealous of Age but warms up to him after the attack on Titarros.

Just as she was about to leave the only planet that gives her some comfort, the Golden Tribe's gateway opened and revealed that Age was alive, and he and Dhianeila were reunited.

The television series was produced by King Records, KlockWorx and Xebec and directed by Takashi Noto and Toshimasa Suzuki, with Tow Ubukata handling series composition, Hisashi Hirai designing the characters and Naoki Satō composing the music.

The first two volumes would also contain an eight-page booklet and stickers of the corresponding DVD cover for a limited time only.
