Mutsuki is a destroyer of the Sakura Empire who appears in the anime Azur Lane Queen's Orders. She is depicted as a young, childlike girl with short brown hair, cat ears, and a tail. Her personality is cheerful, energetic, and openly enthusiastic about sweets, particularly candy. She is often seen in the company of her sister ship Kisaragi, and the two are frequently the target of Ark Royal's overly affectionate attention, which Mutsuki finds bothersome. In Queen's Orders, Mutsuki's role is limited to brief supporting appearances, contributing to comedic slice-of-life moments. As a ship, her notable abilities include a talent for torpedo attacks and a skill that enhances the torpedo performance of allied destroyers. She does not undergo significant character development in the series due to her minor screen time.
