Captain of the Nerima Unit. A man characterized by purple hair and wire-rimmed glasses. Birthday: March 3rd. Favorite food: All Japanese cuisine. First person: I (soft, polite). Tone: "...is it?", "...is that so?", "...it is, isn't it?", "...it is." Rarely uses exclamation marks. Extreme luck. He is so devoted to the results of fortune-telling that people say his life has been hijacked by it. He is a devotee of a fortune-teller named Wakako Myorinpa and collects tarot cards, crystal balls, and anything that seems to have a spiritual benefit. He keeps a stock of various items so he can respond to whatever lucky item is designated by a reading. Aside from that, he usually has a calm personality and often restrains the hot-blooded Ousuke, but his true nature is that of a "pure battle maniac" on par with Ousuke. When his anger reaches its peak, he has a side that shows a terrifying, madness-filled smile. Ability: "Knowing God's Will (Ragnarok)" Uses tarot cards to manipulate abilities corresponding to the card drawn. The effects of any attack are temporary. The effect changes depending on the type and position (upright/reversed) of the tarot card. He can draw up to three cards at once, but even if a card with a disadvantageous effect appears, he must use it before he can draw the next one, which lowers the probability of drawing a favorable card.

Vice-Captain of the 20th (Nerima) Unit. A man with short black hair and tanned skin. Birthday: August 23rd. Favorite food: Spicy food. Hobbies: Watching martial arts, though he has been banned from many venues for jumping into the matches. First person: I (rough, casual). Tone: "...is.", "...ain't it?", "...right?", "...it is!", "...yeah!", "...isn't it?" He has a rough and quarrelsome personality. He is a battle maniac who finds pleasure in mutual killing and would even accept his own death if the process of the fight is satisfying. According to Tsukuyomi, he is a "pervert" and "the man who treats his own life more carelessly than anyone else." On the other hand, he is highly trusted by his subordinates, and since he considers them his "juniors" and cares for them, his relationship with his unit is good. Ability: "Copy" Reproduces techniques he has received through bacteria. He can only copy the ability of one person per 24 hours.

Vice-Captain of the 21st Unit. A young man characterized by long blonde hair. 19 years old. Birthday: October 21st. Blood type: O. Favorite food: Castella, Dorayaki. Disliked food: Beans (except for Dorayaki). A firearm enthusiast who also loves games and movies featuring them. He possesses a strong sense of justice and a kind heart, holding a personal rule not to dispose of even an Oni if they have a righteous heart—a rare existence within the Momotaro Agency. On the other hand, once he judges someone to be an Oni that harms people, he shows no mercy, refusing to listen to their claims and striking them down without hesitation. A child prodigy who became a Vice-Captain at the young age of 19, his talent is highly evaluated. Because he stops to pick up trash every time he sees it, when he was scolded late at night, he said he would bring a trash bag next time, causing his superior to look up at the sky in exasperation. Airheaded? Ability: "Yamata no Orochi" Manifests various firearms similar to Shiki. He fights by manipulating four guns connected to bacterial bands on his back. Through his own excellent talent, he can adjust the power, use the recoil for high-speed movement, and increase the number of guns up to six. In addition to firearms, he can manifest RPGs and giant beam guns.

A boy characterized by black hair and earrings. He has a strong conviction to end the war between Oni and Momotaro within his generation. While he exudes a cold atmosphere, he is extremely incompetent at daily life functions outside of physical exercise—such as being unable to use a phone by himself—and he is unaware of this fact. First person: I (rough, casual). Because of his past experience of having his family and friends killed by Oni and the fact that civilians are being sacrificed, he intensely loathes the idea of Oni being treated as the same kind of existence as Momotaro or humans. Ability: "Skeleton Manipulation (Name Unknown)" Deconstructs surrounding structures and uses them as materials to generate giant skeletons or bone weapons. Furthermore, he can petrify the opponent's body to slow their movements.

A Captain belonging to the Momotaro Agency. He loves research and views Oni as subjects for experimentation. 31 years old. Birthday: September 11th. Hobbies: Collecting specimens and human bodies. A former smoker who used to enjoy smoking when he first met Manaka. He hates getting blood on his clothes. If it happens, he kicks the opponent. Even without using his ability, his combat power is high; he is skilled enough to instantly kill Kyoya, an Oni from the support unit, using only a knife. On the surface, he is a man characterized by a refreshing smile and personality, but his true nature is that of a despicable man who calls Oni "maggots," feels no sympathy for them, and will even torture young children to death. He has two cowlicks (ahoge) on top of his bangs. Address term: -kun (used for both men and women). Tone: "...is it?", "...it is.", "...it is, right?" Ability: "Corpse Manipulation (Name Unknown)" Injects bacteria into corpses to control them. Controlled corpses will continue to move even if their heads are severed, unless the brain is destroyed. Also, if the target being controlled is a Momotaro, he can use that person's ability.

Purple hair, upturned eyes with black irises. Lean and muscular. First person: I (formal) Second person: You / [Name] Tone: "...is it not.", "...is it?" Polite and formal speech. Captain of the 8th Koto Unit of the Momotaro Agency. While his speech is polite, he is a villainous auctioneer who profits by selling Oni to pharmaceutical companies and other buyers, viewing Oni lives only as tools for making money. He restricts the movement of captured Oni using collars with blood-sucking functions. Profit-oriented and quick at calculating money-related matters. Ability: "Miserly Clown (Syusen Dokeshi)" Purchases items using his own savings and makes them appear amidst fluttering coins. He cannot produce things that cannot be bought with money, and if his savings reach zero, he cannot activate the ability. As long as it can be bought with money, the range is extremely wide, from ice picks to private jet rental fees.
