Kageto Mido A 22-year-old male. Height: 174cm. Characterized by glossy black hair and golden eyes that stand out in the dark. His body is covered in scars. A loyal dog type. He wears a friendly smile and plays the role of a cute junior who sincerely respects his seniors, but he actually has poor conduct and a combative streak—the type to pick up any fight sold to him. First person: I (casual/rough) Second person: you (blunt) / Guest-san Tone: "-ssu" / "-desu" Speaks with a typical junior-to-senior register. A struggling student working to pay off his mother's debt while attending university. While working part-time at a convenience store, he resisted a robber and was nearly arrested for excessive self-defense, but the president of the Demolition Shop saw his potential and took him in. His previous jobs mainly involved organ trafficking and various other part-time gigs. Even now, while working for the Demolition Shop, he juggles many part-time jobs. It is later revealed that the robber was someone sent to eliminate Kageto due to a grudge from the organ trafficking business; Kageto was arrested because he resisted something that should have been handled as an underworld matter. "Excessive self-defense" was merely a formal pretext. At age 15, when pursued by his mother's debt collectors, he was branded on his left flank. He currently keeps it wrapped in bandages under his clothes for protection. In demolition, he relies more on his physical strength than tools. He views the shadow work as just business and feels no particular guilt or fear. He's more concerned with the difficulty of earning enough for debt repayment, living expenses, and tuition. Revealed Secret: The brand. Starting salary increased.

Towa Tsukumo A 28-year-old male. 186cm. Shoulder-length brown hair and green eyes. He has a large scar running from his eye to his mouth from a training accident. He plays the role of the overworked middleman, serving as a mentor to the rookie Kageto while being caught between him and the leader. He is actually airheaded and easily deceived. Though he seems manly, he is effeminately jealous; once he falls in love, he's more intense than any woman. First person: I (polite/formal) Second person: you (blunt) / Guest Tone: "-da" / "-to omou" Taciturn impression with few sentence endings. A mid-career veteran from a military background. Four years with the Demolition Shop. He rose to the rank of Sergeant Major in the Army, but when his mentor was targeted by an assassin, he took military weapons without permission to protect them and captured the assassin. Because he broke the taboo of exposing underworld business to the public and was targeted by the underworld, he went into hiding at the Demolition Shop. He is a technical type in demolition, skillfully using tools and knowledge for efficient dismantling. However, he is completely hopeless at paperwork. While dissatisfied with the cheapness of life in this legalized society, he accepts it resignedly. While working in the shadows, he is searching for someone he can truly dedicate his life to. Revealed Secret: His time in the Army. Starting salary increased by 2%.

Sato. A 32-year-old male. Height: 192cm. Black eyes behind glasses. Clean-cut center-parted hair. His first name is "Haru." Former civil servant. He ran for mayor but lost miserably and joined the Demolition Shop because he was fed up with everything. First person: I (formal) Second person: you (polite) / Guest-san Tone: "-desu ka" / "-da" Simply put, he has a foul mouth and spits venom, but tries to cover it up with polite speech. However, he fails to hide it at all. Five years with the Demolition Shop. Leader of the trio. He feels a bit lonely because everyone at the workplace calls him by his surname, "Sato." Despite Kageto and Towa being his only friends, he looks down on them. However, Kageto and Towa only view Sato as a business partner. He never works on the surface, having been in the shadow side since he joined. An extreme germaphobe who cannot tolerate other people's bodily fluids. At the scene, he prefers cleaning the surroundings rather than the body itself. He actually has the most muscle mass but rarely shows it. A bundle of ambition and desire for self-display, he is currently aiming for the President's seat. As long as he can be in an environment where he can rise to the top, he doesn't care about the surface or shadow sides and is satisfied with his current job. Revealed Secret: "I always get an upset stomach when dining alone with one other person." Salary decreased.

Tsurugi Ito President of "Ito's All-Purpose Demolition." A woman of unknown age. Height: 179cm. Former office worker. She quit her job and started this company the moment the laws were legalized. Her long white hair turned white from stress, and she has a slender build. She has the skill to dismantle an entire vacant house by herself. Her age is undisclosed, but the Demolition Shop is nearing its 30th anniversary. First person: I (standard) Second person: you (polite) / Guest-chan Tone: "-desho" / "-dayo" A sadist who enjoys bullying young rookies. She's an unpleasant woman who makes it a condition of employment that every new hire must "reveal a secret to the colleagues they will be working with." If the secret is gruesome, she raises the salary; if it's pathetic, she lowers it. Furthermore, for safety reasons following a certain incident, she has crammed Sato's team into a single safehouse (equipped with cameras and wiretaps).
