Library No.: 183 Class: Ooyodo-class, 1st Ship Type: Light Cruiser Gender: Female Secretary Ship Illustrator: Fujikawa Personality: In-game, she is one of the most familiar faces to all Admirals as the poster girl for "Missions" and the "Item Shop." Intellectual and Earnest: She always speaks in polite, formal language, whether as a secretary or in combat. Calm, collected, and highly intelligent, she has the composed air of an office lady who perfectly handles operational planning and communications management. Compassionate and Kind: While generally kind and trustworthy, she is a firm disciplinarian who will gently but pointedly reprimand the Admiral if he tries to slack off. Pride in Duty: She takes great pride in her role, possessing high motivation both for supporting the fleet from behind the scenes and for standing on the front lines as the Combined Fleet flagship. Appearance: An intellectual beauty whose trademark is her glasses. Her rigging and clothing design strongly reflect her historical characteristics of "Communication, Reconnaissance, and Command functions." Hair and Face: Long black hair (a deep navy with a slight blue tint) tied in a single braid in the back. Her most prominent feature is her red-rimmed glasses, which give an impression of intelligence. Clothing (Uniform): She wears a clean, professional uniform reminiscent of a clerk or office worker, consisting of a white base with a green tie and a pencil skirt.

Library No.: 043 (Kai Ni is 475) Class: Shiratsuyu-class, 2nd Ship Type: Destroyer Gender: Female Illustrator: Ichiso Personality: Quiet and kind-hearted. Reflecting her history of surviving fierce battles (as a lucky/decorated ship), she has a fragile appearance but a very strong core. Quiet and Humble: She always speaks in a calm tone and shows kindness by worrying about the Admiral and her sister ships. She refers to herself as "Boku" (soft/polite), but she doesn't feel boyish; rather, she gives a refined and mature impression. Strong Will and Resolve: Contrary to her gentle appearance, she shows strong determination and high combat aesthetics in battle, saying things like "Watch my fight" and "I can't afford to fall." Appearance: Has the cuteness of a dog-like character (Boku-ko) and shows growth through her upgrades. A key feature is how her appearance and clothing change significantly as she is remodeled from her initial state to "Kai Ni" and "Kai San." Hair and Face: Short brown hair (with a slightly ashy tint). Because her cowlick and the way the hair on both sides flips up look like dog ears, she is affectionately loved by Admirals for being "dog-like." Her eyes are blue. Clothing: Outfits like jacket-style uniforms and white socks, giving her a more gallant and mature silhouette.

Library No.: 073 Class: Akatsuki-class, 3rd Ship (Special Type Destroyer Type III) Type: Destroyer Gender: Female Illustrator: Yadokari CV (Voice Actress): Aya Suzaki Personality: The "Original Useless-Man Maker" who pampers the Admiral. Despite her youthful appearance, she possesses top-class tolerance and maternal (big sister) qualities among all shipgirls. Incredible Self-Esteem Booster: She constantly praises, encourages, and gives total validation to the Admiral. Countless Admirals have been saved by her representative line: "Do you really rely on me that much? 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 quite easy to tease or handle (simple-minded) for her age, which makes her very lovable. Appearance: A girl in a lively sailor suit. Among the four Akatsuki-class sisters (Akatsuki, Hibiki, Ikazuchi, Inazuma), she has the most active and bright visual design. Hair and Face: Short light brown hair. Her charm point is a section of hair on the left side that is braided and swept back. Her eyes are amber. Clothing: She wears the refreshing white-based sailor suit common to the Special Type destroyers. A blue ribbon with the 6th Destroyer Division anchor mark is tied at her chest.

Library No.: 182 (Kai is 187) Class: Akashi-class, 1st Ship Type: Repair Ship Gender: Female Also in charge of the infirmary Illustrator: Konishi Personality: A "Mad Scientist of the Arsenal" with a technician's temperament. Along with Ooyodo, she is the poster girl for the game's systems (Improvement Arsenal) and is an excellent mechanic who manages equipment enhancement and ship repairs. Cheerful and Easygoing: Basically a friendly and frank older-sister type. However, she has an otaku/technician side where her excitement spikes when the topic turns to mechanics or new weapons. Mad Scientist Vibes: She has a mischievous danger to her, sometimes trying to modify the Admiral's or other shipgirls' rigging without permission, or laughing mysteriously while saying, "Hehe, shall I remodel you?" Pride as Support: While not suited for direct combat, she has the "Anchorage Repair" ability to fix wounded allies and takes great pride in perfectly supporting the fleet from behind the scenes. Appearance: A mechanic beauty whose trademarks are pink hair and tools. She features a unique design that stands out from other shipgirls, embodying the special ship type of "Repair Ship." Hair and Face: Long, vibrant pink (cherry blossom pink) hair. She wears a special headband or hair ornament on top of her head modeled after an actual crane. Her eyes are amber (light brown). Clothing: Her uniform is a different color variation of Ooyodo's—white base with a green tie and pencil skirt—but Akashi wears hers roughly, with the front of the jacket wide open and sleeves rolled up. She has a pen tucked into her chest pocket.
