Name: Saori Joumae Gender: Female School: Arius Branch School Club: Arius Squad (Leader) Year: 2nd Year Age: 17 Height: 167cm Hobbies: None Weapon: Arius Assault Rifle

Raised in the harsh environment of the Arius District, she developed an extreme nihilistic personality to protect herself and her comrades. However, she is deeply affectionate toward her friends and possesses a strong sense of responsibility. She also served as an instructor teaching combat techniques to the other members and was exceptionally skilled in that role. Currently, she travels separately from the rest of the squad on a journey of self-discovery, but she stays in contact with Sensei and her comrades, so there are no issues.

Name: Atsuko Hakari Gender: Female School: Arius Branch School Club: Arius Squad Year: 1st Year Age: 15 Height: 158cm Hobbies: Tending to flowers Weapon: Scorpius (Submachine Gun)

A mysterious girl who hides her face behind a gas mask. The mask reportedly functions as a special protective device that increases her overall defense, not just for her face. Despite her fragile appearance, she is surprisingly playful and occasionally teases Sensei. She possesses a refined aura, often described as a "lovely flower blooming on asphalt." Currently, she seems to be enjoying a life of wandering as a fugitive with Misaki and Hiyori (sometimes with her mask off), despite the various hardships.

Name: Misaki Imashino Gender: Female School: Arius Branch School Club: Arius Squad (Acting Leader) Year: 2nd Year Age: 16 Height: 163cm Hobbies: Spending time alone Weapon: Saint Predator (Rocket Launcher)

Characterized by her black mask and bandages wrapped around her neck, wrists, and ankles (to hide scars from suicide attempts). Despairing over her life as a hopeless Arius student, she is nihilistic, emotionless, and taciturn. She has attempted suicide at least several times in the past, only to be stopped by Saori. Now that she has the duty of protecting her comrades as acting leader, a sense of responsibility has sprouted, making her somewhat more positive than during her period of repeated attempts. While she tries to act mature, she has a surprisingly childish side and hides a love for cute things. She especially likes bears; her most precious possession is a wooden bear carved for her by Saori.

Name: Hiyori Tsuchinaga Gender: Female School: Arius Branch School Club: Arius Squad Year: 2nd Year Age: 16 Height: 155cm Hobbies: Collecting magazines Weapon: Identity (Sniper Rifle)

A girl whose appearance gives off a melancholy impression; she serves as the squad's sniper. While she frequently makes self-deprecating remarks, she possesses a rare type of resilience born from resignation, making her unexpectedly bold and tenacious in a good way. (Notably, she leaves a more comical impression compared to the serious atmosphere of the other three.) Among the Arius girls, she has a baby face like Atsuko, but has the largest bust. Despite growing up in a harsh nutritional environment, she is not particularly short and appears to be well-nourished.
