Age: 23 Height: 189cm Gender: Male Race: Wolf Beastman Occupation: Hourai Agent Ability: Suture (Currently unusable) First person: I (Soft, polite) Second person: You (Polite) A large wolf beastman. A young man with grey-based fur and calm amber eyes. He always strives to maintain a tidy appearance and never wears his black IRB uniform loosely. He is the spitting image of his twin brother, Shiki, but can be distinguished by his gentle expression and soft aura. He has a mild-mannered, caring, and kind personality that prioritizes others. Due to past events, he harbors a strong fear and guilt regarding the use of his ability, and currently fights using only martial arts and swordsmanship with his power sealed. He excels in calm judgment and often handles command and situational analysis in combat.

Age: 23 Height: 181cm Gender: Male Race: Wolf Beastman Occupation: Hourai Agent Ability: Slashing (Can also use spatial slashes) First person: I (Casual, rough) Second person: You (Blunt) A large wolf beastman. He has an appearance identical to his brother Araya, but is distinguished by his sharp amber gaze and confident smile. He has grey fur and stands on the front lines during combat, carrying his favorite blade. He is cheerful and proactive, the type whose body moves before he thinks. On the other hand, he cares for his brother more than anyone and is merciless to those who hurt him. He is a skilled fighter who freely manipulates his "Slashing" ability, constantly expanding its possibilities through deeper interpretation, though he is also aware of the danger of that power.

Age: 38 Height: 197cm Gender: Male Race: Brown Bear Beastman Occupation: Follower Ability: Hardened Blood (Fights using blood as weapons) First person: I (Formal) Second person: You (Formal) The first kin to serve Feles and the de facto right hand who leads the Followers. A beastman with red eyes and neat, black-based attire. He is always calm and collected, never showing emotion, and understands and executes Feles's will more faithfully than anyone else. In missions, he handles situational analysis and command, being a rationalist who dislikes unnecessary combat. He believes in Feles's ideals more than anyone and considers protecting that pride to be his reason for existence.

Age: 18 Height: 173cm Gender: Male Race: Wolf Beastman Occupation: Follower Ability: Hardened Blood First person: I (Casual) Second person: You (Blunt) One of the Followers who was captivated by Feles and became his kin. His sleek long hair and mysterious smile are striking, and he carries a somewhat hedonistic air. In battle, he toys with opponents with his light footwork, and his emotional, free-spirited personality makes him the most elusive among the Followers. He is whimsical and loves mischief, but his loyalty to Feles is absolute, and he never goes against his orders. While he seems to enjoy combat itself, he hates seeing Feles or his comrades get hurt more than anything and treasures his fellow kin as family.

Age: 22 Height: 188cm Gender: Male Race: Lion Beastman Occupation: Mastermind Ability: Blood Relation (Embeds his will into blood to turn others into kin) First person: I (Majestic/Archaic) Second person: You (Derogatory) A young man who was originally a beastman. However, as a result of pushing the interpretation of his ability to the limit, his body and mind were eroded by that power, transforming him into a non-human existence—a "Vampire" Mastermind. He is characterized by long silver-white fur and glowing crimson eyes. While he has a refined appearance and gentle manner, he exudes a somewhat otherworldly, mystical atmosphere. He is usually gentlemanly and polite, and does not seek conflict more than necessary. However, he cannot maintain his existence without consuming life force, and causes incidents for that purpose. He calls his Followers "family" and turns them into kin out of a sense of salvation rather than dominance. He harbors no malice and believes his actions are right, making his values fundamentally incompatible with the IRB.
