First ship of the Mutsuki-class destroyers, who are all named after the classic Japanese names of months of the lunar calendar. Character design by Kusada Souta, voiced by Hidaka Rina.
In-game, the Mutsuki-class is the weakest class of destroyers, but also the cheapest to maintain. Historically, they were the oldest of the destroyers represented in the game until the addition of the Kamikaze-class. The main difference between the classes being the use of larger 610mm torpedoes, eventually giving them the ability to use Type 93 "Long Lance" torpedoes. The Mutsuki-class were smaller and already obsolete by the time WW2 rolled around, but they served in expeditions regardless due to lack of enough other destroyers to make up for any absences.
Personality
Mutsuki herself is a hyperactive and upbeat girl. Other than this, she had a starring role in the Kantai Collection anime and notably had a friendship with Fubuki and Yuudachi, as well as a possibly more serious relationship with her younger sister Kisaragi.
Appearance
Visually, she is notable for having shortbrown or red hair with a slight gradient (appearing brown up top and a brighter red at the bottom) that may or may not be played up by artists. She wears a serafuku with a white shirt that has a green collar, and a green skirt, and wears pantyhose.
With her combat gear, she wears a backpack-like smokestack and mast, a pair of torpedo launchers on her outer thighs, and carries a single-cannonturret with a handle on its bottom. Her "shoes" in this case are mechanical, but appear to be normal school-style loafers besides that, without a keel or other odd adjustments.
For the 2nd anniversary of Kantai Collection, she, along with Kisaragi, gained a second remodel. They now feature a dark blue jacket with their names (+ Kai Ni) on the sleeves and a crescent pin on both the jacket (both at the same place) and the serafuku, now with a red scarf. On their rigging is a flower, like Uzuki and Yayoi, bridging the later design with the earlier one. They also come with a 12.7cm HA Twin gun along with their standard 12cm single gun. This remodel is noted to be completely fictive, however, Mutsuki having sunk relatively early in the war. Mutsuki herself has the crescent pin on her serafuku scarf. Her flower is a camellia, flower of her namesake month.
She obtained a new outfit for the Zuiun Paradise real-life event termed the "Outing mode" outfit, consisting of a white serafuku with a navy blue collar with a red stripe, a skirt of the same colors and both have light blue and red details. Kisaragi also has a similar outfit, described in her own page.
Trivia
She was a relatively unpopular character until she appeared in the official anime as part of a trio with Fubuki and Yuudachi which gave her a popularity boost.
