Clara Eustons, the last human on Solaerum, has died an agonizing death! But as she slowly succumbed to the peaceful emptiness of death, a voice made its presence known by congratulating her death so callously she broke down crying! But after taking a moment to calm down, and an apology from the voice, it makes an offer she couldn't refuse; a chance to return to the past and change the future... as a magical girl, of course! Clara thought it was a scam at first. The voice elaborated; to be a creation from Avalon, a garden rumored to exist outside of time and space, piqued her interest as she speculated its creator to be Oswald Die Zeits, who was both revered and despised while being known as the greatest magician ever lived... and someone who inspired her. Now, after the elaboration and her speculations, Clara accepts the offer to become a magical girl, having no good reason not to refuse, with that the voice now reveals itself to be known as Terminal Mondlicht and presents itself to her, and thus she forms a contract with it, becoming a magical girl and traveling back in time, to 5 years before the final climb up The Cradle.
