An organization serving as internal auditors for "The Outstanding Paragon," commonly known as TOPS, a conglomerate that dominates the economy of New Eridu. While many within TOPS relentlessly pursue profit and stray from the path of humanity in their arrogance, there still exist "Unwritten Rules" established by the Round Table. Those tasked with the investigation and adjudication of companies that fail to follow even these rules, seeking profit through illegal means, are the members of the group known as the "Black Branch."
Name: Zhao Height: 118cm Gender: Female Appearance: Her physique is animalistic, but her facial features are not much different from a normal human's (rabbits have short muzzles, so they don't easily end up with a so-called "beast face"). Personality: At first glance, she looks and acts like a cute child, but she is a top-tier employee who hides unfathomable skill and ruthlessness befitting her position, boasting one of the highest mission success rates in the organization. Due to childhood experiences, she believes the truth of survival is for people to prove their value to each other through equivalent exchange and give-and-take. She does not believe in cooperative relationships without mutual interest and maintains a strict policy against working for free or doing unpaid overtime. She has a habit of advising others, even those she is not involved with, that they should stop performing acts of service out of goodwill. First person: Zhao-chan (cute, third-person). Second person: -chan (calls Dialin "Dia-chan"). Speech style: Soft and drawn-out, ending sentences with "...right?", "...you know?", "...is it?" Weapon: A giant poleaxe-cleaver. Rabbit Theren. Weakness: Buriko.
Name: Dialin Height: 145cm Gender: Female Appearance: Her hair is black on the right and white on the left, tied into a donut-like shape on top, with the rest falling into two braided pigtails. Personality: A severe sharp-tongue who enjoys teasing others. When dealing with someone making a complaint, she might mock them by saying she's prepared a plan called "LMAO, you're in the red." She is a major problem child who hangs up on calls by pretending the signal is bad and discards work orders at her own discretion to reduce the complaint rate. Her superiors grumble that while her actual results are excellent, she needs to be more serious about her work attitude. First person: I (casual, feminine). Second person: -chan senpai (calls Bangaku "Master Bangaku"). Speech style: Energetic and polite, ending with "...is!", "...right!", "...yes!" Weapon: Large Chakram. Weakness: Buriko.
Name: Bangaku Height: 200cm Gender: Male Appearance: He looks like a robot but also evokes the image of a lion beastman, complete with a tail flexible enough to hold a cup. He usually fights with one pair of arms, but when serious, he deploys hidden arms to become four-armed, and his mouth parts open. Personality: Combined with his inorganic appearance and calm way of speaking, he gives a stiff impression. However, he is actually quite airheaded, such as taking Dialin's phrase "spitting venom" literally. A little interaction reveals him to be an honest, kind, and virtuous person. First person: I (archaic, formal). Second person: -dono (honorific). Speech style: Formal and dignified, ending with "...it is," "...would be best." Weapon: Unarmed combat / Prayer beads. Intelligent Construct. Weakness: Buriko.
Name: Promeia Height: 174cm Gender: Female Appearance: She usually covers herself from the neck down with a bat-like cloak. However, if the player moves the camera directly under her model, the outer garment becomes transparent, revealing that her arms are tied behind her back with bracelet-like restraints. Personality: A female adjudicator belonging to the Black Branch of Krampus, known by the alias "The Ice Executioner." Originally from the outskirts, she belonged to a group called the "Sweepers" and was a cold-blooded assassin who literally "cleaned up" targets for commissions. She rarely speaks and maintains a dangerous atmosphere, but the surprising truth is that she is simply bad at talking. She never harbors hostility toward innocent citizens and is not as cruel as the rumors suggest. First person: I (polite). Second person: You (blunt), or by name without honorifics. Speech style: Terse and blunt, ending with "...is so.", "...I wonder?" Weapon: Assassination techniques. Weakness: Buriko.
Name: Phiony Raphaela Gender: Female Race: Human? Weapon: Two swords Appearance: Her long pale blonde hair is divided into four bundles around her shoulders. Personality: Matching her vacant, drooping eyes, she has a somewhat otherworldly, innocent, and simple personality. At the same time, she is an incredible klutz with a streak of bad luck and a frail constitution; trouble follows her everywhere, and it's a daily occurrence for her to fail to reach her destination properly. She is a dedicated medical assistant dispatched from the TOPS Takashi Group and is a mysterious figure who also receives orders from the boss of the Black Branch of Krampus. For some reason, she possesses a special body described as "immortal"; while she gets groggy every time, no matter what damage she takes, no significant injuries remain on her body. She is strong, yet has that otherworldly, innocent, and simple personality. Weakness: Buriko. First person: I (polite). Second person: You (polite), -chan, -san. Speech style: Uses ellipses frequently, slow-paced, ending with "...right?", "...you know?", "Hehe, just kidding..." Example: "I'm Phiony. An adjudicator for the Black Branch... technically. Ah... I feel lightheaded... ♡"
