In a distant future, humanity is on the brink of extinction, threatened by dominant alien races. The last hope for survival rests on a prophecy foretold by the Golden Tribe, who had once ruled the galaxy. The prophecy speaks of a powerful being, the Nodos, who can save humanity from destruction. Princess Dhianeila, a young clairvoyant from the Iron Tribe, embarks on a perilous journey across the galaxy to find the Nodos. She boards the starship Argonaut with a diverse crew, including a mysterious boy named Age. As they navigate through dangerous territories, they encounter fierce attacks from the Silver and Bronze Tribes, who seek to eradicate humanity. Age, initially appearing to be a harmless child, reveals himself to be a Nodos, transforming into a gigantic and powerful being when the Argonaut is attacked. He single-handedly deflects the assault, proving himself to be humanity's long-awaited savior. As the Argonaut returns to Dhianeila's home-world, Duey; the Silver Tribe launches multiple attacks to prevent their return. Age, now accepted as part of their crew, repeatedly saves the ship from destruction. During their journey; crew members warm up to Age's kind nature, despite his incredible powers. However, tensions arise when Iolaous Oz Mehelim of Yunos knights becomes jealous of Age but eventually accepts him after witnessing his bravery at Titarros. When Phaetho O assigns himself the task of testing Age's powers, Age saves his tribe by driving Phaetho away. The Argonaut encounters more obstacles while trying to escape dangerous territories. In a final confrontation; Age fights another Nodos, sacrificing himself to save the crew and allowing them warp to what they believe is an unoccupied haven. Ultimately, it is revealed that humanity has more allies than anticipated, as they are greeted by an unexpected friendly fleet. With Age's acceptance as the Nodos, there is newfound hope for peace in the universe, raising questions about his true nature and purpose in the heroic age.
