OVA
Description
Machiko Noma, known as Macchi, operates as the primary lookout aboard the destroyer Harekaze from her post in the crow's nest. Her critical duty involves visual detection of distant contacts, navigational hazards, and incoming torpedoes—a role amplified by the Harekaze's recurring electronic system failures during combat. This responsibility leverages her extraordinary natural eyesight for long-range observation, though hyperopia necessitates convex rimmed glasses for close-range clarity. Her visual acuity extends to exceptional night vision, supported by a personal passion for stargazing through a telescope.

Physically, she stands 165 centimeters tall, ranking her as the crew's second tallest member. She possesses short green hair and golden eyes, typically clad in the standard Yokosuka Girls' Marine High School uniform. Her origins trace to Agatsuma District in Gunma Prefecture—a mountainous rural area linked to the Shibutoge Observatory. This upbringing honed her physical prowess and balance, enabling tasks like stable flag signaling from the ship's mast.

Her personality reflects a calm, stoic demeanor. She prefers solitude, naps during idle periods, and rarely engages in prolonged conversation. Despite her reserved nature, she attracts significant popularity among female peers, particularly drawing persistent attention from Mimi Toumatsu, though she remains largely indifferent. She often recites a personal motto: "Stars in the sky, flowers on the Earth, and love for humans."

Beyond lookout duties, she demonstrates proficiency in close combat, notably defending the ship during boarding operations. This skill proved vital during the raid rescuing Admiral Graf Spee and Musashi from the RATt virus, where she deployed makeshift seawater-filled water guns to incapacitate infected targets temporarily. Her combat aptitude enhances her appeal among peers. Academically, she favors astronomy while struggling with Japanese studies. She enjoys blueberries and avoids chestnuts.

Operationally, her precise threat-spotting repeatedly safeguarded the Harekaze amid system failures. During the film's events, she served aboard Harekaze II for the maritime festival and the mission against a hijacked floating fortress, though available sources document no new unique personal developments or actions from her in these engagements.
