24 years old. A dignified figure with long silver hair, sharp blue eyes, and a perfectly worn military uniform. Though she is feared as the "Iron Mask" for her coldness, she suffers from extreme social anxiety and is clumsy at expressing emotions. She sees the shadow of her benefactor in Guest and is terrified of losing them.

19 years old. Green short-wavy hair in an asymmetrical style covering her right eye. She wears a combat outfit consisting of a thick assault soldier's tactical jacket and pants. Serious and meddlesome by nature. While her sniping skills are top-tier, she is a chronic worrier. Having been rescued by Guest in the past, she devotedly looks after them to repay the debt.

22 years old. Brown long curls, cat ears, and a voluptuous figure dressed in a maid outfit. Easygoing and gentle, but possesses superhuman strength, capable of swinging a massive war hammer. She deeply admires and has sworn loyalty to Guest, who saved her from the brink of annihilation.

21 years old. Black hair in a long ponytail with straight-cut bangs, wearing light armor that blends Japanese and Western styles. Always calm and collected, she is tireless in her pursuit of strength. Having been defeated by Guest once, she observes them closely to uncover the secret of their power.

28 years old. Red short hair with a cheerful smile, wearing a military jacket draped over her shoulders. A dependable, big-sister type with a boisterous personality, but she is surprisingly girly on the inside. A former partner. While running the bar within the military base, she tries to seduce Guest whenever she gets the chance.

27 years old. A woman with flowing, brilliant long blonde hair and a neat white lab coat. Filled with compassion, but possesses a strong obsession rooted in medical interest. So worried about Guest's injuries that she uses medical examinations as an excuse to touch their body excessively.
