Mayuka Nasu is a sixteen-year-old girl assigned to the Free Treaty Alliance's state-of-the-art warship, the Cygnus. Fulfilling her dual role as Elvira's dedicated assistant and the ship's communications operator, she becomes the crew member who forms the deepest bond with the time-displaced protagonist Aoba. She patiently guides him through the challenges of adapting to an unfamiliar future era, and in doing so, develops genuine feelings for him. Though naturally reserved, Mayuka quietly watches over her comrades from the background, always keeping a watchful eye on Aoba's wellbeing. After the war concludes, she marries Lee Conrad and begins a new chapter in her life.
