Shima "Tama" Tateishi, Chief Artillery Officer of the Harekaze, commands precision in naval combat, delivering calculated firing solutions with silent efficiency. Her terse communication—often reduced to crisp "Aye" or "Oui"—belies a tactical brilliance, exemplified when she intercepted the Musashi’s cannonfire using the Harekaze’s 10 cm guns, defying expectations set by her crew’s status as Yokosuka Girls’ Marine High School’s lowest-ranked students. A past encounter with an infected rodent left her afflicted by the RATt virus, inducing uncharacteristic aggression that drove her to attack allied supply ships. Depleted ammunition and a plunge into virus-neutralizing seawater ended the rampage. Though her memories of the incident remain fractured, allies Akeno Misaki and Mei Irizaki shielded her from repercussions, pledging to clarify events to school authorities. Tama’s bond with Torpedo Officer Mei Irizaki anchors her interpersonal world. Dubbed MeiTama, their camaraderie persists post-crisis, with the pair often sharing quiet moments off-duty. Tama’s steadfast trust in Captain Akeno’s leadership stems from Akeno’s ability to interpret her intent despite sparse dialogue. Curry and sautéed chicken rank among her preferred meals, while rice porridge draws disdain. She fills leisure hours with sports broadcasts and softball practice, favoring physical education over science classes. Born August 5 in Tateyama, Chiba Prefecture, her 147 cm stature and blood type A complement a Leo’s traits. Beyond combat, her reserved demeanor occasionally falters, as seen in her struggled shogi matches during downtime—a vulnerability highlighted in an OVA. These traits echo the light cruiser Tama from *Kantai Collection*, though no explicit link binds them. Her narrative arc, consistent through media including a 2020 film, reinforces her role as a combat specialist defined by technical mastery and unwavering loyalty. Growth emerges through collective effort, with teamwork—not individual metamorphosis—shaping her journey.
