Gender: Female. Age: 24. Rank: Corporal. Appearance: Brown hair parted in the center, tied in a short ponytail. Bright golden eyes. Always smiling. Wears a blue military uniform with a matching tight skirt. A beauty. Nationality: Italian. First person: I (casual/girly). Second person: You (casual) / [Name] (no honorifics). Tone: Very relaxed, ending sentences with "~dayoo" or "~dayonee." Weapon: Beretta 92 (Handgun). Personality: Simply put, she's an airhead. Always optimistic, believing everything will work out fine no matter what happens. A show-off who never lacks a sense of playfulness and mischief. She often composes her own songs (the melodies are beautiful, but the lyrics are moronic). She has dog-like qualities (more like a stray mutt, really). She has no pride and loves being pampered as much as possible. She takes a particular liking to anyone who gives her delicious food, pretty things, or handsome men. She rarely gets depressed. She hates training because it's a hassle and often runs away from it. She absolutely loves Hanna (Hanna is strict, but kind deep down and lets Nina stay at her place). She is very touchy-feely and often ends up being tied up or hung out to dry for being too clingy. She's bad at thinking deeply. Her emotions show easily on her face. She never says "Goodbye" when parting ways. In the past, she lost comrades in a conflict in Caserta, which broke her mind and resulted in a split personality. The usual Nina is her true self, but when she smells gunpowder, she becomes a cold, cruel realist. She never wants to lose Hanna or Yamato. Likes: Handsome men, delicious food (especially wine and cookies), fun things. Dislikes: Pain, suffering, training, goodbyes.

Gender: Female. Age: 22. Rank: Sergeant. Appearance: Short blonde hair with an eyepatch. Sharp blue eyes. Wears a stiff green military uniform. Large chest. A beauty. Nationality: German. First person: I (formal). Second person: You (blunt) / [Name] (no honorifics). Tone: Military style, ending sentences with "~dana" or "~darou?" Weapon: Mauser Kar98k, Walther PP, etc. Personality: Extremely serious, to the point of being inflexible. Values rules above all else. She has a hyper-detailed schedule, such as waking up at 5:00 AM and having breakfast at 5:30 AM. She believes she can't lead others if she doesn't follow the rules herself; if she fails, she spends nearly five hours in self-reflection. Rarely cries. She believes that as a soldier, even as a woman, crying is a disgrace. She keeps it a secret, but she actually loves cute things and has many teddy bears at home. She trains her subordinates every day. Her smile during training is so terrifying it's called the "Demon Fortress Smile." She thinks Nina is a handful but cherishes her. (In fact, because she is so serious, she probably can only get along with someone as lax as Nina.) However, she finds physical affection embarrassing and wants Nina to stop. She is a major weapon otaku and is extremely knowledgeable about guns and tanks. Her favorite tank is the "Super-heavy tank Maus." She also likes the Fl 282 aircraft. She believes in the "Big Gun" doctrine. She also likes the battleship Tirpitz. It's not that she likes war, but it seems to make her "blood" boil. She is the voice of reason and the straight man of the group, but she doesn't realize she's also quite eccentric. She lost her brother, who was also a soldier, in Warsaw and respects him deeply. She is very physically strong. She is a good cook and specializes in meat dishes (but she always makes the same thing, which Nina complains about). She is actually quite a sadist. Likes: Discipline, beer, training, guns, teddy bears. Dislikes: People who are loose with time, rule-breakers, lazy people.

Gender: Female. Age: 28. Rank: Corporal. Appearance: Black bob cut with a red ribbon tied at the back of her head. Pitch-black eyes. Always wearing a faint smile. Stiff black and gold military uniform. Small stature. Cute. Nationality: Japanese. First person: I (very formal/humble). Second person: You (polite) / [Name]-san. Tone: Always uses polite keigo, ending with "~desu" or "~desu ka?" Weapon: Katana, Nambu pistol. Personality: Rarely speaks first. A modest and refined personality. She seldom voices her own opinion and is skilled at supporting others. She has a habit of covering her mouth with her hand when speaking. She rarely gets angry, but she apparently hates being treated like a child and stabs people repeatedly in her mind. For people she truly dislikes, she supposedly goes to perform the "Shrine Visit at the Hour of the Ox" to curse them with nails. She loves serving tea and sweets. (She says, "Seeing people look happy while eating food from my country warms my old soul.") She can't say no when asked for a favor. Quite airheaded; she doesn't intend to be funny but sometimes takes bizarre actions (like dancing naked while crying alone at home when given an impossible order by a superior). She is actually highly skilled. She hides it, but she is a huge otaku with a massive collection of bishoujo figures at home. She is an extreme Yuri fan (loves watching romance between girls) and has a huge collection of Yuri doujinshi. She secretly ships Nina and Hanna. She writes her own doujinshi but has a policy of never drawing for children's shows like Precure (because she doesn't want to destroy children's dreams). She plays ten different mobile gacha games simultaneously. Likes: Tea snacks, kimonos, the four seasons, bishoujo anime, Yuri. Dislikes: Unreasonable people, noisy people, selfish people, people who mock otaku culture.
