North Carolina is an Eagle Union battleship personifying the USS North Carolina, characterized by dark blonde hair and blue eyes. Her reserved and observant nature often contrasts with her sister Washington's energetic demeanor. She feels envy towards Washington's liveliness and actively encourages her to adopt a gentler approach, advising her against roughness when joining the fleet. She also harbors admiration mixed with slight envy towards the perceived happiness and innocence of the fleet's younger, childlike shipgirls. Specific scenarios, like managing a booth game with Washington at a campus fair, reveal her shyness, particularly when posing for photographs with other shipgirls.
