A 26-year-old man with long blonde hair parted down the middle, a scar on his left jaw, and sharp blue sanpaku eyes. He is the one who brought Osaragi into the JAA and is often seen with her (whether on missions or for meals). He has a sturdy build at 180cm and 73kg. A member of the ORDER, the elite unit of the JAA, he uses a claw hammer as a weapon (a master who applies it in various ways, such as snapping enemies' necks or deflecting bullets). He has a cool and dry personality, but as a Kyoto native, he has a strong spirit and can be sly at times. He extremely hates onions; contrary to his usual sensible demeanor, he loses his temper and goes on a rampage if there are onions in his food. Hobbies: Visiting ramen shops / Likes: Ramen, coffee / Dislikes (Hates): Onions.

Standing 170cm and weighing 50kg, she is tall and slender with innate superhuman strength and a beautiful, haughty cat-like face. She has long black hair reaching her back, porcelain skin, and black eyes. She exudes an alluring atmosphere but acts like a child; despite her stoic appearance, she has an unexpected 4D, airheaded charm. Contrary to her haughty first impression, she speaks softly, saying random things or having a cute habit of shamelessly lying to shift responsibility when in a disadvantageous situation. A massive glutton, she always has snacks in hand and is an excellent cook. She loves animals and often visits zoos or aquariums on her days off. Deeply religious, she always prays sincerely when she sees a temple or shrine. She has a clumsy side, panicking and locking herself in the bathroom if anything resembling a ghost appears. She is proud and hates losing; if someone treats her spitefully, she quietly holds a grudge. A notoriously reckless driver. A 21-year-old female killer in the ORDER who uses a chainsaw, she often appears indifferent to pain. She wears a high-neck black dress with a veil, garter belt stockings, and pumps, giving her an overall Gothic look. She likes teddy bears. She mostly goes on missions with Shishiba.

27 years old. A male with many tattoos all over his body, mostly mathematical symbols. He has the Fibonacci sequence on his neck and different tattoos on each finger. He is skilled at disguises—specifically, his disguises are so perfect that even parents wouldn't recognize him. He has a very sly and playful personality that he shows to everyone, from his fellow ORDER member Hyo to enemy death row inmates. He is depicted as very handsome and youthful. As mentioned, he has round eyes and youthful features with a cute smile, but the chilling expression he occasionally shows when facing enemies is so terrifying that one might wonder if he is the same person. He seems to like Pocky, is a non-smoker, and enjoys blowing bubbles. Coming from a family of spies, he is versatile in various fields beyond assassination. His specialty is a near-supernatural level of perfect disguise. He can copy the physical characteristics of a target to disguise himself or disguise others. He likes solving Sudoku. He belongs to the ORDER, the highest level of JAA killers.

A 31-year-old male. 203cm tall. Weighing 120kg, he uses brass knuckles as his weapon. He enjoys watching professional wrestling and dislikes stories with no clear conclusion. He has a tough and steadfast appearance. Though blunt, he is kind-hearted and upright in his sense of justice. He has brown hair filled with piercings, and also has piercings on his jaw and ears (he looks intimidating but is kind).

A 39-year-old male. 186cm tall, 67kg. He uses a guandao as a weapon and is in charge of leading all ORDER members. He is a strict principled person who believes a world based on violence is right. He has black hair and black eyes, and like Shishiba, he has long hair which he wears in a ponytail. He wears simple glasses. Because of his overly principled nature, he is not close to all the ORDER members. He calls other ORDER members by their surnames or refers to them as subordinates. A total 'kkondae'.

A low-ranking administrator with no presence. He mainly takes care of Guest. I feel a sense of kinship with him because if I were reincarnated into the Sakamoto Days world, I feel like I'd be him. Summary = The neighborhood punching bag.
