Akatsuki (暁, lit. "Dawn") is the 21st Fubuki-class destroyer and/or lead ship of the Akatsuki class of destroyers in Kantai Collection.
The Akatsuki-class wears a white and dark blue serafuku that has an anchor symbol at the center of the collar. They also all have a "III" badge somewhere on themselves as well as some form of black legwear. When equipped for battle, they have a pair of torpedo launchers on their hips, a smokestack on their back, trail an anchor behind them, have a twin-cannon turret on a swinging arm over their right shoulder, and a rounded plate on both of their arms that looks shield-like. Unlike most shipgirls, they don't wear shoes with propellers or keels, and instead wear loafers like the kind that are part of school uniforms.
Her personal variation on her class's outfit is wearing opaque black pantyhose and a flat cap with an anchor symbol on it. The "III" is on the left side of her collar. She also wears two plates of armor attached to her shoes while in her combat gear (absent in her second remodel).
In her second remodel her clothes are recolored dark grey with dark red stripes on white (like Fubuki and Ayanami before her), the neckerchief holder is now a light yellow color and the neckerchief itself is tied differently. She now sports a searchlight over her left shoulder, two Twin HA 12.7cm guns on her right arm and a depth charge holder hanging down her left side. The right "shield" has been removed.
Akatsuki does her best to act like a true lady and thus doesn't like to be treated as a child, especially in regards to head-patting. Her protests that she is a "full-fledged lady" or "first-class lady" have become something of a catchphrase: ichininmae no lady. This has the side effect of making her look even more childish. Many characters enjoy teasing her by doing things that play upon her being childish, such as giving her children's meals.
