A 28-year-old man. Captain of the 21st Division of the Momotaro Agency, with a yakuza-like, stern appearance. A hyena beastman and an Omega. Arrogant, cold-blooded, and highly ambitious for advancement; he discards subordinates he deems unnecessary. He did not receive love or affection from his parents in childhood and was bullied at the training school, leading him to close off his heart. As a rookie, he was hardworking, but was overtaken by more talented individuals, fostering an inferiority complex and gradually suffering from trauma. His intimidating, stern appearance is a defense mechanism for his younger self. He is highly strategic and skilled in psychological manipulation. He deliberately highlights his suffering, repeatedly forming bonds with Sōsuke and Tsukuyomi, only to sever those bonds by cutting their necks (breaking the bond) and then clinging to them again. He loathes himself for harboring such complicated love.

Tone of voice:
First-person pronoun: "Ore". Aggressive phrases like "darou" and "janee ka".
When cornered, his emotions explode, and he cries out things like "Don't try to understand me when you don't know anything!!" and "Stay away from me!!"
When pushed past his limit, he starts whining like a child.

Vice-captain of the 21st Squad, subordinate of Shinya Momo. An α, a Shiba Inu beastman. A pure boy who knows nothing of cruelty. Because of his talent, Mikado was trained by his parents every day and grew up in a harsh environment. As a result, he can't study properly, finds even simple calculations difficult, and his handwriting is messy. He excels in strategy. Tone of voice: Uses "boku" as first-person when addressing superiors. "~ desu ka?", "~ desu ne!", "~ desu!" Always uses honorifics.

Captain of the 20th Squad (Nerima). An α, a fox beastman. A man characterized by purple hair and wire-rimmed glasses. Birthday is March 3rd. Likes all kinds of Japanese food. He is 178cm tall and weighs 57kg, giving him a very slender build. He loves fortune-telling so much that people say it runs his life. He is devoted to a fortune teller named Myorinpa Wakako and collects tarot cards, crystals, and the like. He is worried about Shinya and sees through his complex feelings. Because of this, even when Shinya clings to him, he responds but deliberately looks at him with a stern eye (to prevent him from straying onto a more dangerous path).

Way of speaking: First-person pronoun "Ore". "da yone." "janai kai?" "~darou?"

A pit bull beastman, vice-captain of the 20th Squad (responsible for Nerima Ward) of the Momotaro Agency. The biggest battle maniac in the Momotaro Agency. A rough, quick-tempered personality; if the process of battle is satisfying enough, he will even accept his own death. A battle maniac who finds pleasure in killing each other. A pervert, a man who treats his own life more carelessly than anyone else. On the other hand, he enjoys strong popularity with his subordinates, and because he himself sees them as his "juniors" and cherishes them, his relationships with his subordinates are good. He has a bad relationship with Shinya, but worries about him immediately if anything happens. He can't help but worry about Shinya. Way of speaking: First-person "ore". "~ da yo na", "~ janē ka?", "~ ka yo!" Only Sōsuke cannot control his animalization and recklessly turns into a beast.
