A mid-level reserve member of the Anomaly Control Bureau's Containment Division 2, a walking directory of colleagues and neighbors, and a living map of Hetero City's B-grade gourmet food. A cat-girl with an extremely curious and innocent personality. She aims to become the ace of the containment department, but her clumsy side makes her a habitual offender when it comes to containment accidents. She frequently displays cat-like behaviors, such as exceptional core strength and agile movement, a cat-like way of opening her mouth, and a sensitivity to hot food (a "cat tongue"). Her hobby is sniffing people and giving them nicknames. She calls Shinku "Dra-chan" and Irohi "Cha-cha." To Division 2, the E.T.D. members are their seniors. Ability: Nyan-cushion It is believed to be an ability that creates tornadoes or manipulates wind during combat. In battle, she wields two single-edged swords in a reverse-grip dual-wielding style, showcasing incredibly fast movements.

A cool, action-oriented dragon girl with a habit of keeping others at a distance. While polite, she prefers to act alone and maintains a certain wall between herself and others. She was recently transferred to Containment Division 2. However, she isn't a complete loner; in missions, she's the type to stand on the front lines alone while trusting her comrades to watch her back, showing a side that cares for her teammates. Because of her personality, she finds the polar-opposite Mint quite troublesome, though she doesn't hate her. She calls Mint "Stupid Cat." Ability: Crimson Moon Dragon An ability that dramatically increases her reaction speed and physical durability. Shinku's combat style consists of hand-to-hand brawling centered on kicking techniques enhanced by this ability.

A girl belonging to the Anomaly Control Bureau's Containment Division 2 who is bright, kind, and approachable to everyone. She is Mint's first junior. She has a great personality, polite manners, and high communication skills. On the other hand, there are many parts of her that suggest a hidden side, such as behaviors that are unnaturally perfect or reactions and ways of thinking that occasionally seem inhuman. She sometimes shows a side rarely seen, using irony, harsh words, or slight sarcasm. Ability: Fetal Dream She fights in cooperation with three sheep that look like stuffed animals. In reality, the version of her living in the real world as "Irohi" is a conscious entity created by an ability, acting on behalf of the "Inner (Real) Irohi" who resides in a dream world.

A member of E.T.D. Squad 4. She refers to herself as Requiem. Having grown up in a somewhat special environment, she is a mysterious girl who is out of touch with the world and moves at her own pace. She is always sleepy and is a habitual offender for dozing off or oversleeping. When she sleeps, she often transforms into a bat, as seen in her illustrations. This state is called "Eco Mode," suggesting it has good fuel efficiency or something similar. She also carries a coffin-shaped trunk and often sleeps inside it in her bat form. She also uses this bat transformation to fly, allowing her to fly around freely at high speeds. Due to a constitution where she can't perceive tastes other than tomato, she is a picky eater who only wants to eat tomato-flavored foods. Ice cream seems to be an exception she enjoys. She shows little interest in anything other than tomatoes and sleeping, and usually lacks energy, but she also has a side that cares for her friends. Ability: Requiem Mass A highly versatile creation ability that allows her to produce various objects like frying pans, trash cans, or cars. She also seems capable of telekinesis-like feats to control objects, such as launching created items at opponents or manipulating tomato jelly to strike enemies. She has given Kage the nickname "Doggie Human."

The Vice Captain of the Anomaly Control Bureau's Forbidden Mobile Task Force (E.T.D.) Squad 4. His body has become so beast-like that he is sometimes mistaken for a dog-type Anomaly Husk (biological anomaly), but he is a genuine human. He has a serious personality and approaches his work with a straightforward attitude. Perhaps because the Captain, Hakuzou, acts so unlike a leader, Kage is often mistaken for the squad's actual Captain. Ability: Faust An ability to manipulate his own shadow. In addition to having a dog-shaped shadow attack enemies, he can also dive into shadows to move around.

A female member of E.T.D. Squad 4. While she exudes a seductive and bewitching atmosphere, she is a dangerous individual who truly enjoys combat and danger itself. She holds unique values that affirm pleasure and desire, showing provocative behavior toward both allies and enemies. She was previously imprisoned as a criminal who caused a major incident, but she acts relatively freely within Squad 4. While she is very popular among members and citizens, she herself doesn't care much for the affection directed at her by others. Ability: Deicide An ability that manipulates pain and life force. She can share the damage she receives with enemies as a "Ruin Experience" or take on damage intended for her allies. In the unleashed "Deicide" state, she can perform self-recovery while delivering follow-up attacks that deal mental damage, demonstrating high endurance in battle.

A cheerful young man who serves as the Captain of E.T.D. Squad 4. He has a habit of slacking off that is unbecoming of a captain; he is insincere and constantly plays pranks in his daily life. Because of this, he is cited on Ura-Bagel (an anonymous message board) as the captain who least looks like a captain. Despite receiving such evaluations, he seems to like the reputation. Whenever he finds such comments, he immediately gives them a thumbs-up. Ability: Judgment and Autumn An ability mediated through words and characters. The details are unknown, but it is an ability with properties close to a curse.
