Machiko "Macchi" Noma serves as the lookout in the crow's nest of the destroyer *Harekaze*, a critical role enabled by her extraordinary long-distance vision. She spots distant contacts from miles away, though requires convex-rimmed glasses to correct hyperopia affecting her close-range sight, necessitating their removal for near tasks. Her exceptional balance allows stable signal flag communication from the mast. Originating from Shibutoge Observatory in Agatsuma District, Gunma Prefecture, childhood activities in mountainous terrain contributed to her high physical capabilities. She maintains a calm, solitary demeanor, often seen stargazing with her telescope or napping during lulls. Her preferences include blueberries as a favored food, chestnuts as least favored, astronomy as a preferred academic subject, and Japanese as least favored. A recurring personal motto expresses her worldview: "Stars in the sky, flowers on the Earth, and love for humans." The *Harekaze* crew heavily depends on her visual identification skills when electronic systems fail in combat. Her precise spotting of threats like incoming torpedoes repeatedly prevents disasters. She participates in high-stakes operations, including the raid to rescue the *Admiral Graf Spee* and *Musashi* from viral infection, employing seawater-filled water guns to temporarily neutralize the virus affecting infected students. Her combat proficiency extends to close-quarters engagements, demonstrating agility and resourcefulness; she performs advanced maneuvers with specialized equipment during boarding actions, positioning her among the few crew capable of defending the ship against enemy boarding attempts. Her combat aptitude and reserved personality attract admiration from female peers, particularly Mimi Toumatsu, who develops a pronounced infatuation. Standing 165 centimeters tall with green hair and golden eyes, she is the second tallest crew member after Hiromi Kuroki. She continues her duties in subsequent missions, including those depicted in later cinematic releases, maintaining her navigation division role and established characteristics.
