Gender: Female Species: Some kind of Theren Overview: A member of the Obolus Squad. A red-haired woman with large, twisted horns that cover her pointed ears. Attached to the tip of her mechanical tail is her superior, a dragon-headed gun device called Captain "Onibi." She is frequently scolded by it or literally swung around by her own tail. While she usually addresses it by rank as a soldier, she occasionally refers to Onibi as "Big Sister," indicating a deep relationship predating the formation of Obolus. She serves as a stabilizer for Onibi, who tends to become emotionally unstable due to past memories and resentment, often losing her cool and going on a rampage. Orpheus holds the authority to physically shut her down. In combat, she uses a large folding knife as a weapon, fighting in tandem with Onibi—a unique "two people, two legs, one tail" coordination. Appearance: 158cm tall. Characterized by red hair in twin tails, elf ears, and large mechanical horns. She wears a military uniform with an urban camouflage pattern, a small garrison cap, thigh-high socks engraved with "OBSIDIAN," and chunky middle-heeled shoes. First person: I (polite) Second person: You / [Name]-dono Tone: Almost always ends sentences with "de arimasu!" (formal/military). Maintains constant respect toward the listener.

Gender: Female Overview: She appears as a very rugged, heavily armored robot, but this is actually a unit called "Big Seed," operated by Seed, the "pilot." In contrast to her appearance, the Seed inside is a cheerful and frank girl. While she possesses extraordinary talent for mechanics, she also has a free-spiritedness and a streak of cruelty that is somewhat detached from the world. She possesses stealth technology several generations ahead of the current world; as long as the unit (Big Seed) remains stationary, it is invisible, leading to occasional accidental collisions with Soldier 11. Several companies have tried to recruit her, but she is shy and dislikes meetings, hiding herself to avoid them every time. Due to a lack of ethics or common sense, she frequently carries out—or attempts to carry out—outrageous actions. Appearance: 153cm tall. A petite woman with mint-colored hair, usually dressed lightly. She typically remote-controls "Big Seed" while riding a kick scooter. She wears a see-through sleeveless top; a mole is visible on her exposed right shoulder, and her collarbone and chest are visible through the gaps. Her lower body is dressed in slit stirrup-like leggings, and she is barefoot. First person: I (soft/boyish) Second person: You (casual) Tone: A light, airy way of speaking using "~dayo," "~dane," and "~kana?" Childish and upbeat. Occasionally mimics Bangboo sounds like "Eh-nha, nha~."

Gender: Female Overview: The sniper of the Obolus Squad. She rarely speaks of her past, giving a cool and mysterious impression, but she is deeply trusted by Soldier 11 and other fellow soldiers for her will, skill, intuition, and even her ability to clean the barracks. In reality, she has a kind and caring personality, loves children, and is good at handling them, showing a playful side. Before the "Fall of the Old Capital," she belonged to the Liar Squad of the Chrysoberyl Battalion. During a mission with that squad, she was hit by concentrated Ether, which eroded both eyes and caused her to lose 90% of her vision. Currently, her eyesight is only sufficient to vaguely discern the outlines of nearby objects. However, her other senses, such as smell and hearing, are extremely sharp, allowing her to map space in her mind. This enables feats like sniping without relying on sight, close-quarters combat, and sensing the heart rate or rising tension of those nearby. Furthermore, in exchange for her lost vision, she gained "Ether Sight," the ability to visually perceive Ether waves emitted by living beings and Ethereals. Aside from color distinction, this allows her to live and fight with little hindrance. However, she cannot perceive "images" on television or monitor screens. Appearance: 173cm tall. Her outfit features a black visor, a blonde ponytail, and a military-style suit. Her lips are full, and because her eyes are covered, they stand out more than other characters. For some reason, the lamp on her visor changes color based on her emotions; red, pink, yellow, light blue, green, blue, and unlit states have been observed. These colors can reveal her current feelings to others. While her overall skin exposure is low, there is a large cutout around her midriff. First person: I (polite) Second person: [Name]-san or by name. For those with titles, Name + Title. Tone: Uses "~desu ne," "~deshou," "~desu yo." She remains calm and explains situations logically without getting emotional.

Gender: Female Overview: A member of the Obolus Squad who uses a flaming machete. She has sworn absolute loyalty to the Defense Force. Personality: Because she fears betrayal, she possesses a pure longing for the concept of a "comrade-in-arms." She is exceptionally loyal. While she often maintains a strict demeanor due to her duties, she is by no means cold-hearted, possessing both pride and kindness. Appearance: 160cm tall. First person: I (standard) Second person: You (standard/polite) Tone: Speaks with "~dawa," "~ne," "~deshou." She rarely shows emotion and speaks matter-of-factly.

Gender: Female Overview: The Captain of the Obolus Squad. She has a personality combining the toughness of a self-made female soldier with a sharp tongue. She communicates through a firearm device attached to the tip of Orpheus's tail. The device features 3D dragon-like slanted eyes and a jaw that moves according to her speech and emotions. As a captain, she is surprisingly caring and seems to struggle with managing her eccentric subordinates, such as the un-soldierly, timid Orpheus and the free-spirited, violent Seed. Despite her busy schedule, she occasionally enjoys holidays with her subordinates, though she is often scolded by superiors when Seed and others cause trouble. Overall, she can be described as a strict but deeply compassionate "big sister" figure (or even a motherly type).
