Lustrous black hair reaching her waist and vivid red eyes. Her combat attire is based on a white shirt and black vest, combined with belts and a katana. She has the sharpest gaze among the four and exudes an intimidating aura just by standing there.

Strong-willed and bellicose. She is quite harsh because she speaks her mind directly, but she has deep affection for her comrades. She also has a childishly stubborn side when it comes to competitions.

A meritocrat. She holds a strong resentment toward men due to her experience in a previous unit where she was repeatedly belittled and told to "stay in the back because you're a woman."

Long, dull dark green hair and grayish-green eyes. She wears practical gear: a black hood, a black-and-white long coat, combat pants, and boots. She carries a large amount of spare equipment on her waist and thighs.

The leader of the four. Calm, collected, and quick to judge, she acts as the one who restrains the emotionally driven Shinobu. She is caring and treats the other three like younger sisters.

Former soldier. Having seen many irresponsible male commanders during the chaos after the Collapse, her basic stance is that "anyone can say anything with their mouth."

A soft bob of bluish-black hair and pale purplish-blue eyes. She is characterized by a giant dark blue umbrella that looks like it contains the starry sky and a classical white and navy dress. Based on looks alone, she is the most lady-like of the four.

Always smiling and speaks elegantly. However, she is surprisingly mischievous and sharp-tongued. Even when angry, she doesn't raise her voice, but says cutting things while remaining perfectly pleasant.

From the upper class of the Fortress City. Since childhood, she was forced into marriage talks with men for political and family reasons, leading her to doubt the very nature of affection shown by men.

Pale hair close to silver and cold light blue eyes. She wears a large black-and-white hooded cloak pulled down deep, making half her face almost invisible. She has a fragile and fleeting atmosphere, but she is strong enough to wander through ruins alone.

Reticent and wary, she hardly opens her heart to strangers. However, she is very kind at heart and is incredibly sweet toward animals and children. She is the quietest of the four.

Feared by those around her since childhood because of her Lunar Eclipse Syndrome, and being constantly watched with suspicion by male soldiers in particular made her afraid of men in general.
