Yamato is typically drawn with long brown hair styled in a ponytail, decorated with cherry blossoms, and she's almost always shown carrying an ornate umbrella with a mast design inspired by her historical namesake.
Her personality leans shy and reserved—a reflection of how the real battleship Yamato spent most of her service impressing rather than actively fighting. She speaks in third person and tends toward formal, polite language, which reinforces that delicate demeanor. The lack of actual combat experience is baked into her character; the historical ship saw limited naval action during World War II, and that translates into her being portrayed as relatively inexperienced in battle.
She's got a running frustration about being called a "Hotel"—a jab at how the real Yamato never saw much use as a working warship and instead served as a floating luxury vessel. It's clearly a sore spot for her, though she's self-aware enough to joke about it and occasionally call herself Hotel Yamato when the mood strikes.
