Ruin Atë commands the Dryads, warrior devotees of the goddess Eris, charged with orchestrating her resurrection and unleashing chaos across realms. Her ancient origins span millennia, her might forged through an unbreakable bond with Eris. In the era before the central conflict, she sought to fuse Eris’ soul with young Shōko, transforming the child into a living vessel. This scheme was foiled by Shōko’s sister Kyōko and Scorpio Milo’s interference, driving Atë into retreat.

She later spearheaded the hunt for Eris’ corporeal form, clashing with Kyōko and Delphinus Mii. Confronting Saori Kido, Atë wielded the Golden Apple to plunge Shōko into a trance, unleashing Eris’ soul as a winged serpent—a pivotal step toward the goddess’s rebirth.

Atë exploited the Great Tree Uterus, which imprisoned Kyōko’s essence, to spew Seeds of Evil across the world. Collaborating with Dryads Emony and Phonos, she sowed discord among Athena’s forces by exploiting Sanctuary’s internal strife. Her pact with the resurrected Gemini Saga magnified threats against Athena, enabling celestial assaults through hurled meteorites and Sanctuary’s destabilization.

Her combat prowess manifests in the Million Hatreds technique, summoning venomous vines that adapt to adversaries’ tactics, pierce armor, and unleash atomic-level devastation. She wields telepathy, teleportation, and dominion over flora. When unleashing her full might, her cosmic and physical power surges, briefly rivaling Gold Saints like Scorpio Milo.

Yet her dependence on Eris’s waning influence left her exposed. Crucial defeats came from manifestations of Sagittarius Aiolos’s spirit repelling her onslaughts and the Saintia’s unraveling of her machinations. Her arc culminates in the collapse of Eris’s revival and her own schemes, though her ultimate fate remains shrouded in the annals of conflict.
