Beauty, a mysterious entity entombed within an iron-like rock formation high in Earth’s mountains, resists all terrestrial attempts to breach its shell. Known as the "beauty memory," it embodies humanity’s collective memories from the past century. Eiji, an Earth Federation Forces member, triggers the narrative by unearthing this artifact, which intertwines with the legacy of Amuro Ray—a key figure in the Universal Century’s historic conflicts.

Dormant within a memory capsule, Beauty awakens as a humanoid figure, delivering cryptic monologues that stress humanity’s survival through continuity. It declares that connecting to Amuro’s Legacy—a doctrine linked to the RX-78-2 Gundam—is vital to transmit Earth’s memories to a "new Earth" via the Ring Colony. This orbital generational vessel, central to mankind’s exodus beyond the solar system, becomes the focal point of Beauty’s mission.

Advocating cyclical renewal over divine purpose, Beauty spurns humanity’s self-destructive impulses, urging coexistence through mutual goodwill. Echoing philosophies like Hannah Arendt’s critiques of totalitarianism, it acts as both narrative catalyst and metaphor, exhorting characters to confront recurring conflicts and pursue disarmament.

Beauty ignites factional strife: Earth Federation forces plot to dismantle the Ring Colony, fearing its militarization by EX, a penal colony of war criminals. Meanwhile, agents AG and Yuria champion Beauty’s vision, deploying the reactivated Gundam to safeguard the colony. Beauty’s revelations about humanity’s fraught history culminate in purging rogue military elements, enabling the colony’s departure.

Though enigmatic in origin, Beauty is hinted as an artificial construct designed to preserve historical data across epochs. Designated a "memory," it interfaces with the Gundam’s systems, resonating with data within the rock. This fusion of technology and metaphysical essence bridges humanity’s past struggles with its interstellar aspirations.
