Marina is the mother of Flit Asuno. Her husband is mentioned by Flit in episode 11. However, no details are known about him, including his appearance or name, and it seems that he had already passed away by the time Flit was old enough to remember. When Flit was seven years old, she was attacked by the UE and died. On her deathbed, she entrusted Flit with the AGE Device. In the final episode, she appears as a phantom in front of Flit along with Yurin L'Ciel, Grodek Ainoa, Woolf Enneacle, Don Boyage, and Hendrick Bruzar. In the first part of the novel version, it is mentioned that she is a scientist who invented the DODS system to aid in outer space exploration
