"Dallos Special" is a two-episode OVA that serves as a condensed version of the original 1983 "Dallos" series, often regarded as one of the earliest OVAs in anime history. The story is set in a future where humanity has colonized the Moon, exploiting its resources to sustain Earth. The lunar colonists, living in harsh conditions under Earth's oppressive control, are treated as second-class citizens, leading to growing resentment and unrest.

The narrative centers on Shun Nonomura, a young colonist who becomes involved in the resistance movement against Earth's authoritarian rule. Shun is initially apathetic but is drawn into the conflict after witnessing the suffering of his fellow colonists. The resistance is led by Alex Riger, a charismatic and determined figure who seeks to liberate the Moon from Earth's exploitation. The group's efforts are complicated by the presence of Dallos, a mysterious ancient structure buried beneath the lunar surface, which holds significant technological and symbolic importance.

As tensions escalate, the colonists' struggle for autonomy becomes increasingly violent, with Earth's military forces deploying advanced weaponry to suppress the uprising. Shun's journey from a passive observer to an active participant in the resistance mirrors the broader themes of rebellion and self-determination. The story explores the moral complexities of revolution, the cost of freedom, and the clash between individual agency and systemic oppression.

Key characters include Shun's older brother, Takeshi Nonomura, who serves as a contrasting figure, advocating for peaceful coexistence with Earth despite the colonists' grievances. The dynamic between the brothers highlights differing perspectives on resistance and survival. Additionally, the enigmatic presence of Dallos itself becomes a focal point, with its origins and purpose shrouded in mystery, adding a layer of intrigue to the narrative.

The condensed format of "Dallos Special" streamlines the original series' plot, focusing on the core conflict and character arcs while maintaining the thematic depth of the story. The OVA captures the essence of the colonists' struggle, blending action, political intrigue, and speculative science fiction elements to create a compelling narrative about the fight for independence in a dystopian future.
