Noah O Antikythira, a member of the enigmatic Antikythiron magical race, appears as a pink-haired child of eight, her small frame standing at 121 cm. Her early life was haunted by isolation and adversity, stripped of her family after being born without the ability to wield magic. Mocked for this perceived flaw, she retreated into the solace of a library, where dusty tomes unveiled the ominous secret of the "Great Evil God"—a revelation that irrevocably colored her understanding of the world.

Though magic eludes her, Noah’s sharp intellect and vivid imagination thrive. Years of solitude forged her into a deft hand at domestic chores, with cleaning as her preferred task and a humble rice omelette as her culinary specialty. Books became both refuge and passion, feeding her curiosity and scholarly tendencies.

Her path collides with Astra Ludger Doomsday, a retired knight, when she boldly infiltrates his home, stubbornly declaring herself his servant. This unlikely partnership underscores her tenacity and resourcefulness as she adapts to her self-assigned role, all while bearing the invisible scars of abandonment and whispered threats of divine darkness. The narrative anchors itself in her resilience, domestic precision, and quiet fascination with forces beyond mortal grasp, leaving her journey rooted in these defining threads.
