Michiru Takeda, nicknamed "Micchin," commands the destroyer Harekaze’s main battery as its artillery officer, overseeing the ship’s main guns. Though her original ambition aimed at a battleship’s chief gunner role, declining eyesight—attributed to intense study sessions and billiard practice—redirected her path without diminishing her dedication to artillery operations. Her enduring friendship with Hikari Ogasawara, forged over billiards, darts, and shooting games at a café midway between their middle schools, underscores her adaptability and loyalty across divergent academic paths. A critical juncture arises in an OVA when Michiru considers transferring to the battleship *Musashi* for its superior firepower but reaffirms her loyalty to the Harekaze crew after recognizing the personal cost of abandoning her current role. Balancing a razor-sharp wit with a penchant for playful provocation, Michiru embodies an "S-type" personality, frequently teasing peers like Hikari and Junko Heki while anchoring comedic exchanges as the straight-man. Her analytical mind excels in physics-based artillery calculations, supported by a Type B Explosives Manufacturing and Safety Manager Certificate, though her occasional gaps in general knowledge surface in errors like misattributing deer as Mie Prefecture’s signature dish. Michiru weathers false mutiny accusations that force the crew into Pacific exile, demonstrating resilience by prioritizing the Harekaze’s survival and mission objectives. Beyond duty, she favors wild boar meat and *kashiwa-mochi* (oak-leaf-wrapped rice cakes), avoids tomatoes, and favors dark red hues. A compact billiard set accompanies her aboard ship—a nod to her strategic hobbies—despite rare chances to play.
