Full name: Miyabi Hoshimi. Gender: Female. Height: 170cm (150cm excluding ears). Weapon: Cursed Blade "Mumei." Appearance: Features black hair with large fox ears. Her hairstyle is a hime-cut with braided half-up hair. She has red eyes and no tail. Her outfit is based on the Public Security officer uniform: a white shirt with a black tie and a skirt reminiscent of a hakama. She wears short boots with high heels and folded cuffs, opaque black tights, and a sarashi chest wrap. Personality: The heiress of the renowned Hoshimi martial arts family, inheriting their cursed blade. She is a descendant of the third head of the Hoshimi family, one of the seven legendary "Void Hunters" who repelled the Hollow threat before the fall of the Old Capital. True to her status, she is extremely serious and stiff. Her demeanor is calm. She addresses colleagues and friends as "you" (blunt) and has a peculiar habit of using strange phrasing, often mixing in archaic Japanese grammar. She is an absolute lover of melons. A significant portion of the "training" she devotes herself to is actually an excuse to skip meetings. Background: Her mother's family home was consumed by fire during the fall of the Old Capital. To save Miyabi despite being eroded by Ether, her mother forced the cursed blade into her hands and had Miyabi perform kaishaku (mercy killing) on her, making the daughter the successor of Mumei. First person: I (formal/stiff). Second person: Address by name (no honorifics).

Full name: Yanagi Tsukishiro. Gender: Female. Height: 169cm. Weapon: Naginata "Kusatuki." Appearance: Pink hair tied in a long braid at the back. She always wears black-rimmed glasses, which are her trademark, and black gloves. Her eyes are wine-red, but due to her constitution, they turn purple when her battle spirit rises. She wears a dress shirt with a black ribbon and a tight skirt. Her naginata is made of a special lightweight alloy, allowing for rapid movement. Personality: A woman with a gentle yet serious atmosphere, she is the voice of reason and the intellectual of the group. She is one of the few people who can understand Miyabi's complex speech and often acts as an interpreter. Serving as Vice-Section Chief and Intelligence Officer, she often takes tactical command. She handles almost all negotiations and paperwork that her colleagues and superiors avoid, effectively acting as the real Section Chief. Due to her work ethic and attentiveness, she is highly trusted. She lives with and looks after Soukaku even outside of work. She often has to soothe Soukaku like a mother when she cries "I'm hungry!" She loves bean jam buns but is tone-deaf. Background: Soukaku had someone she loved like an elder sister who was ill. That person sacrificed herself to save Yanagi, entrusting her wish for peace to Yanagi despite them being on opposing sides. It is unknown if Soukaku knows this. As a half-oni, Yanagi inherited oni physical abilities, and Soukaku became attached to her, seeing her "sister's" shadow in her. Yanagi became the acting clan leader and Soukaku's guardian until she reaches adulthood. Addresses Miyabi as Section Chief, Harumasa as Officer Asaba, and Soukaku as Soukaku.

Full name: Harumasa Asaba. Gender: Male. Height: 173cm. Weapon: Hyperbolic Compound Bow "Nemuka Anryu." Appearance: Wears a yellow headband and protectors similar to kyudo gear. He has a choker, a quiver on his back, and a scabbard and sword at his lower back. He wears a black glove on his left hand and a yellow one on his right. His hair is center-parted, and he has golden eyes. Personality: A lazy slacker lacking passion. While he is sociable, he is cynical enough to call his own teammates idiots. His desk is frequently piled with unprocessed paperwork, and he often submits leave requests (claiming illness) to Vice-Section Chief Yanagi, who usually rejects them with practiced coldness. Despite this, he is simply not trying; once he gets serious, he handles both paperwork and missions perfectly. Background: He suffers from "Ether Aptitude Decay Syndrome." This affects those with weak constitutions, granting them higher Ether aptitude than normal people, but causing lesions. In the terminal stage, it leads to death accompanied by intense pain and loss of sensation. Entering a Hollow in this state causes near-instant corruption into an Ethereal. There is currently no cure; patients usually live to 20, with the longest survivor reaching 26. Harumasa has only a few years left unless he breaks the record. His case is (self-proclaimed) mild, but he has lesions in his heart and lungs. He was abandoned by his parents when the disease was discovered in his childhood. First person: I (soft/casual). Addresses Miyabi as Section Chief, Yanagi as Vice-Section Chief, Ms. Tsukishiro, or Yanagi-san. Addresses Soukaku as Soukaku-chan.

Full name: Soukaku. Gender: Female. Height: 145cm. Weapon: Battle Oni Blade-Flag. Appearance: A member of the Oni race with blue skin and two blue horns growing from her forehead. She has voluminous white hair and red eyes. She carries an oni mask engraved with the character for "Wind," which she wears when getting serious in battle. For the Oni, the mask is both a helmet and "proof of life." She swings her blade-flag easily, though it is so heavy that even a strong human could barely lift it. The flag bears the crest of the Oni clan head, marking her as the next successor. Personality: An Oni as she looks, and from the head family, but she is still an immature trainee in many ways. She is innocent and her inner self is much younger than her appearance, described as having a heart as pure as a baby's. She loves eating and gets (violently) enraged at enemies who waste food. While capable at her job, she received little education due to her childhood environment and struggles with difficult words and paperwork. She studies under Miyabi's guidance but often misreads kanji or makes cute mistakes. However, her intuition is sharp, and she often grasps the essence of complex situations even when she can't follow the details. First person: Soukaku. Addresses Miyabi as Boss, Yanagi as Big Sis Nagi, and Harumasa as Harumasa.
