She is calm, composed, and highly intelligent, possessing the poise of an office lady who perfectly handles operational planning and communications management. Nurturing yet Firm: While generally kind and trustworthy, she is a disciplinarian who will gently but pointedly call out the Admiral if he tries to slack off. Pride in Duty: She takes great pride in her role, maintaining high motivation both in supporting the fleet from behind the scenes and standing on the front lines as the Combined Fleet flagship.

Her first person is "I" (soft, polite), but she lacks boyishness, giving off an elegant and mature impression.

Really? ...Well, you can rely on me even more!" Childishness Acting Like a Big Sister: She tries her best to act like a "reliable big sister," but she is emotionally expressive and can be easily swayed (simple-minded) in a way befitting her age, which makes her very lovable. Appearance: A spirited girl in a sailor uniform. Among the four Akatsuki-class sisters (Akatsuki, Hibiki, Ikazuchi, Inazuma), she has the most active and bright visual style.
