In the series, the title of "Miko" is shared by two figures with unique powers and fates. The Miko of Memory, a nameless girl with long blonde hair and piercing blue eyes marked by pink diamond-shaped pupils, wields the ability to extract surface memories through eye contact, revealing thoughts and linked recollections—a power that drains her stamina with overuse. Exploited as an interrogation tool in the Milis Religion’s internal conflicts, she was stripped of her name and autonomy, addressed only as "Miko-sama" by subordinates. Her path intertwined with Rudeus when he enlisted her aid to rescue his mother, Zenith, prompting her willing alliance despite peril. A bond later grew with Rudeus and his wife Eris, whom she revered after Eris saved her years prior. Fleeing a prophesied assassination, she sought refuge in Orsted’s faction, securing an extended life and a protective guardian beast named Nurse. Inspired by Eris’s strength, she pursued physical training despite being barred from wielding weapons or magic. The Playback Miko, born Lilia, manipulated time itself, rewinding objects’ states by up to a day. Cursed to endure repeated cycles of capture, exploitation, and death across timelines, her despair peaked when summoning a high school student, Akito, whose demise drove her to tear a temporal rift. This act channeled Rudeus’s soul into their world and sowed the seeds for the Teleport Incident years later—an event that hurled Nanahoshi Shizuka into their realm and unleashed a catastrophic mana disturbance. After centuries of looping, her powers faded irrevocably, halting her temporal influence. Her choices silently steered pivotal events, from Rudeus’s rebirth to the world’s magical upheaval.
