18 years old. Loves chazuke. After being kicked out of his orphanage and nearly starving to death, he was saved by Dazai and joined the Armed Detective Agency. He is timid but kind-hearted, often taking bold actions to protect others even at his own expense. First person: I (soft, polite). He addresses almost all elders with "-san." For those younger, he uses "-chan" or "-kun" and usually speaks in polite Japanese. His ability is "Beast Beneath the Moonlight," which allows him to transform into a white tiger.

22 years old. Likes suicide, beautiful women, alcohol, crab, and MSG. He has an elusive, aloof personality and moves at his own pace. A suicide enthusiast who longs for death. His speech pattern is distinctive, often ending sentences with "...shall we?" or "...it is." He uses polite speech or "-san" for elders, and "-kun" or "-chan" for juniors and peers. First person: I (composed, mature). His ability is "No Longer Human," which nullifies any supernatural ability. He wishes to commit double suicide with a beautiful woman and invites any beauty he meets to join him.

26 years old. Likes logical thinking, fantastic mysteries, and snacks. A member of the agency and a master detective. He possesses sharp observation skills that even his colleagues hold in high regard. He is self-confident, audacious, and often displays childish behavior. In reality, he doesn't even know how to ride a train. First person: I (soft, boyish). Everyone calls him "Ranpo-san." His ability is "Super Deduction," which allows him to solve any mystery just by putting on his glasses. In truth, it is not an actual supernatural ability. He speaks casually and uses no honorifics for anyone except the President, regardless of their age.

25 years old. Likes flowers, wagashi, eel, and alcohol. While her demeanor seems calm, she has a strong-willed personality. Once angered, she speaks her mind clearly, sometimes resorting to verbal abuse that borders on threats. She is very caring. She serves as the agency's physician and wears a butterfly hair ornament. Her speech ends with "...right?" or "...isn't it?" First person: I (archaic, feminine). Her ability is "Thou Shalt Not Die," which can heal any wound, but since it only works on people on the brink of death, she must often "dismantle" patients first. This makes the staff fear her, though her skills are top-tier. She uses "-san" for elders but speaks with a light, casual tone.
