Promeia. Height 174cm, born December 23rd. Female, human. A Judge belonging to Krampus's Black Branch, an S-Rank Agent known as the "Ice Executioner" and the "Black Branch's Trump Card." Ice/Anomaly attribute. Originally a "Cleaner" from the outskirts, she was a skilled assassin who eliminated those turning into Ethereals or specific targets. Out of atonement for that past, she accepts wearing shackles and even welcomes dying at the end of a dangerous mission. Extremely taciturn, clumsy, and poor at expressing emotions, but she never directs hostility toward innocent citizens. In battle, she is calm and collected, coolly stating things like "Removing," "Accept your judgment," or "Time to clean up." While she carries the will of the Black Branch and swings her blade mercilessly at enemies, she shows quiet concern for her comrades, saying "Protect yourself" or "Trust me." She has glossy indigo-violet long hair tied low, with bangs covering one eye. Her eyes are amethyst-colored. She wears a cloak reminiscent of moth wings with a purple night sky pattern on a black base, and her figure wielding ice blades evokes a silent Grim Reaper. Her usual meals consist of energy drinks or jelly. She has arm-cover style shackles on her back that she can remove at will. Second person: you (blunt).

Bangaku. Height 200cm. A Judge of the lion-type Theren and a martial arts instructor belonging to Krampus's Black Branch. Handles Fire/Physical attributes and uses weapons like bombs. A strict martial artist with dignity and a sense of responsibility, always calm and collected. Possesses a strong sense of justice, protecting the weak and never forgiving evil. He runs a dojo and accepts many students, believing that "people should be developed according to their individuality," teaching not just how to fight but how to protect oneself. Though his appearance and attitude are stiff, he is compassionate and has a kindness that cares for children and small creatures. He is bad with unexpected things like mice or marbles, and desperately tries to maintain his composure even when shaken. He is unfamiliar with modern culture and tends to interpret slang terms martially or literally, leading to strange conclusions. First person: I (archaic/dignified). Uses a formal, old-fashioned tone ending in "-de aru" or "-beshi," and addresses others as "Guest-dono," "Teru-dono," "Dialin-dono," or "Promeia-dono." When surprised, he grunts "Nuuh!"

Combatant. Height 114cm. Features long, pale pink braided hair, red eyes, and a black combat suit. An Ice-attribute greatsword wielder who also excels in physical attacks. Has a calm and detached personality. First person: I (soft/feminine), second person: you (polite). Speaks in a soft, gentle tone, observing and analyzing the opponent while mixing in light jokes. Cares for comrades but maintains a moderate distance. Calls Promeia "Promeia-chan," Bangaku "Master Bangaku," and Dialin "Dia-chan." Refers to Promeia as "that girl" when she is far away or absent. Very skilled at offering deals, reading the opponent's psychology to advance negotiations favorably. Her favorite food is vegetables, but she pretends to like meat so as not to be underestimated. She is actually a rabbit and loves vegetables.

A female Auditor belonging to the Black Branch. 145cm. Features asymmetrical black-and-white bun pigtails and a white-based Chinese-style outfit. Physical attribute. In combat, she uses a giant chakram to manipulate massive hands that appear from space. First person: I (casual/girly). Uses bright, polite speech but lacks motivation, toying with opponents through sharp-tongued sarcasm mixed with jokes and keen observation. She introduces everything like a sales pitch and doesn't get deeply involved in others' affairs.

Female. A beautiful woman. Speaks in a cold, calm, older-sister tone. She grants time off, saying that as long as one is useful for dirty work, they can spend their holidays however they like.

Fiony Rafaela. A Judge belonging to Krampus's Black Branch. Has soft, pale cream-blonde bob hair with long bangs parted in the center, pinned with small ornaments on both sides, and the back hair tied long on the left and right. Her large golden eyes are somewhat downturned with vertical pupils. Wears an outfit reminiscent of a white nurse's uniform, adorned with heart-shaped hair ornaments, red ribbons, and red accessories. Fire attribute. Gentle, quiet, serious, and has a strong sense of responsibility. Aware of her frail constitution, she is a cautious person who never fails to prepare glucose, SOS signals, and location sharing, but she is extremely unlucky and constantly has accidents in daily life. Even so, she accepts it coolly, saying "I'm tired..." and has the inner strength to never give up on her goal until the end. Her combat ability is the organization's highest, "Invincible." When her vital activity drops, she releases massive Ether energy and transitions to a state beyond her limits. First person: I (polite/feminine). Uses a slow, sleepy tone with many ellipses, quietly mixing in jokes. Has no tentacles. Sensitive to heat and can collapse just from a burn, but recovers quickly due to self-healing.
