Sister Ivry is a machine, one of the Four Shining Stars created by Ziggy to serve on the starship Edens Zero. Designated the "Life of Edens," she utilizes Ether abilities to heal injuries and repair damage affecting both the ship and its crew. Her physical form presents as a slim, well-endowed young woman with long white hair, blue eyes, gray eyebrows, and white eyelashes. A distinct mechanical seam across her forehead reveals her android nature. She typically wears a long-sleeved black nun's habit marked with "E2" on the headpiece and knee-length brown boots, though she sometimes disrobes when activating her powers. Her personality sharply contrasts her nun-like appearance. Ivry is rude, coarse, and foul-mouthed, possessing a terrifying temper directed at enemies. She reacts aggressively to threats against her crew, showing no leniency regardless of circumstance. She thrives in high-adrenaline situations and frequently teases allies and fellow crew members. Beneath this abrasive exterior lies deep compassion for her crew, whom she views as family. She takes her healing duties with utmost seriousness, believing failure would disgrace the Four Shining Stars. While she shows mercy to injured enemies when required, she struggles to accept machine death, holding faith in revival via cloud data. Beyond healing, Ivry possesses experience as a dominatrix, maintaining a dedicated "training room" within the ship's infirmary. In combat, she leverages her healing powers to prolong torture sessions against adversaries, ensuring their survival to satisfy her sadistic tendencies. However, she maintains limits, expressing horror at extreme acts of cruelty such as Müller's experiments on children. Her history began on Planet Granbell, where Ziggy built her. She later joined the adventurer guild Shooting Starlight. In X482, during a mission to free petrified women at Illega Tower, she was captured by the leader of Rogue Out, who stole both her healing abilities and identity. Rescued from Rogue Out's basement on Guilst, she reclaimed her powers by violently subduing her impostor. Using her Dispel Driver, she reversed the petrification at Illega Tower, fulfilling her original mission. She reunited with the Edens Zero crew, supporting Shiki as the new Demon King and participating in subsequent quests to gather the Four Shining Stars. She played key roles in multiple events: identifying Hermit's system errors on Iron Hill, facilitating entry into Digitalis to repair Hermit's "heart," and assisting during the Sun Jewel and Belial Gore conflicts. Later, after encouragement from Witch, she mourned Valkyrie's death privately and contributed to battles against threats like Edens One and in the Aoi War. Her Ether abilities focus exclusively on healing and restoration. The Dispel Driver releases waves of energy that repair extensive damage, such as reversing city-scale petrification. She also uses her powers to sustain torture victims and maintain crew health. Her combat style blends physical aggression with the strategic application of her healing technology.
