Nemure Omoigo, Sora no Shitone ni

A family was driving home from a maternity hospital with their newborn baby, Orine. Satomi and Yasunori were filled with joy as they anticipated their new life together. However, their happiness was shattered when a sudden accident occurred, leaving Orine orphaned and alone. Nineteen years later, Orine has grown up and is on the run from the police after an incident. She encounters Yuri Aoshima, a member of a shady organization, who offers her a way out by taking her to an experimental space station. Only Orine can enter the unmanned station, where she is surprised to find her mother, Satomi, waiting for her. As they spend time together, Orine and Satomi make up for lost time, while Yuri's true intentions and Satomi's identity remain shrouded in mystery. With a man known as "SENSEI" involved in taking over the station, Orine's search for the truth deepens.
