Nemure Omoi Ko, Sora no Shitone ni

A family is traveling in a car after leaving a maternity hospital, excited to bring their newborn daughter, Orine, home. A sudden accident leaves Orine an orphan. Nineteen years later, she is on the run from the police after being involved in an incident. A woman named Yuri Aoshima, linked to a mysterious group, reaches out to her. Orine agrees to Yuri's request to visit an experimental space station, the only place she can access. Inside, she finds her mother, Satomi, who appears as she did in her twenties. Confused, Orine reluctantly helps Yuri shut down the station, hoping it will reveal answers about her mother. As they spend time together, Orine seeks to understand Satomi’s true nature, Yuri’s intentions, and the role of a man named "SENSEI" in the unfolding events.
