Sleep tight my baby, cradled in the sky

In a tragic turn of events, a joyful family returning from a maternity hospital faces an unimaginable accident that leaves their newborn daughter, Orine, orphaned. Nineteen years later, Orine navigates a life filled with turmoil and uncertainty, often evading law enforcement due to her complicated circumstances. Amidst the chaos, she encounters Yuri Aoshima, a mysterious figure linked to a clandestine organization, who presents her with an unusual proposition: a journey to an experimental space station that promises an escape from her troubled existence.

Upon entering the station, Orine is met with an astonishing revelation—her mother, Satomi, appears before her, seemingly unchanged and in her twenties. As they reconnect, the bond between mother and daughter deepens, offering them a chance to reclaim lost moments. However, the situation grows increasingly complex with Yuri's ulterior motives, Satomi's enigmatic identity, and the looming presence of a figure known as "SENSEI," who has plans for the space station. As Orine delves deeper into the mystery surrounding her family's past, she inches closer to uncovering the truth that could change everything.
