Shia "Nomu" Nomura is Deputy Captain of the Yamato-class battleship *Yamato* (K117), serving Yokosuka Girls' Marine High School's maritime fleet. Her surname Nomura (能村) signifies "ability, talent, skill, capacity" and "town, village," while her given name Shia (進愛) combines "advance, make progress" and "love, affection." She enters the narrative during the Yokosuka-hosted inter-high maritime tournament. Reporting to Captain Tōmi Miyazato, Nomura fulfills her duties supporting the *Yamato*'s command structure when pirates seize critical infrastructure, including a floating water purification plant and a sea fortress. During the assault to retake the pirate-held fortress, the *Yamato* coordinates its bombardment with the other Yamato-class battleships *Musashi* (Y118), *Shinano*, and *Kii*. Their combined firepower breaches the fortress defenses, creating the opening needed for the destroyer *Harekaze II* to infiltrate and disable the facility. Her responsibilities and actions throughout this crisis align with her role in combat operations and fleet coordination.
