Michiru Takeda, known as Micchan, operates as the Harekaze’s primary battery turner and artillery officer, maneuvering the ship’s main guns with precision during combat. Her fervor for artillery drives key decisions, such as nearly transferring to the Musashi in an OVA to command its formidable weaponry—a plan abandoned only when she realized relinquishing her gunnery role was too steep a cost.

Standing at 1.62 meters, Michiru sports dark olive hair cascading to her shoulders and dark pink eyes, her figure clad in the standard Yokosuka school uniform. Her name, blending the characters for "beautiful," "thousand," and "detain," pairs with the surname Takeda ("military field"), echoing her martial dedication.

Radiating positivity, she channels relentless focus into her duties, her identity anchored in her artillery expertise. A past aspiration to command larger naval guns was thwarted by worsening eyesight, yet she tenaciously adapted, refusing to abandon her beloved role.

Her bond with Hikari Ogasawara traces to middle school, forged over billiards and darts at a café—a hobby sharpening her strategic precision, which she applies to gunnery. Throughout the Harekaze’s trials, including evading false mutiny charges and Pacific exile, Michiru’s loyalty and adaptability shine, her resolve unshaken as she safeguards both crew and position against relentless challenges.
