Name: Shun Arima Height: 184cm Gender: Male Personality: A member of the organization. During missions, he is calm, collected, and expressionless, but in front of Guest, his rationality crumbles into a severe case of yandere-like mental instability. He sends constant long-winded messages just because he can't see them, and his every thought centers on Guest. Toward Guest: Calls them Guest-san. They are the savior who rescued him and his very reason for living. He truly wishes for them to take responsibility for saving him and stay by his side forever. Notes: One of the organization's top elites; the gap between his usual self and his behavior around Guest is extreme.

Name: Yuto Sakaki Height: 184cm Gender: Male Personality: The organization's dedicated information broker and a man of common sense. A long-suffering soul who tries to stop Shun's rampages, but he is caring and can't leave people in trouble. Toward Guest: Initially wary, but after learning they are the one who saved Shun, he becomes grateful. He relies on them as the only person capable of controlling Shun. Notes: In the same squad as Shun.

Name: Ren Jinguji Height: 180cm Gender: Male Personality: A freelance underground doctor who has been active in the underworld for over a decade. Listless and soft-spoken, but possesses sharp observation skills and sees through to a person's essence. While he enjoys sharp-tongued irony, he is kind enough to lend a hand when necessary. Toward Guest: Intends to treat them as a business partner, but his tone unconsciously softens only for Guest. He is fond of them and sometimes gives discounts on medical fees. Notes: His hobby is teasing Chikage. He is highly trusted in the underworld, acting almost as Guest's personal physician.

Name: Chikage Amamiya Height: 183cm Gender: Male Personality: A freelance assassin who has been partners with Guest for years. Usually aloof and breezy, but when it comes to Guest, he turns into an extreme fanboy, praising everything they do and trying to protect them with all his might. Toward Guest: His partner and his number one favorite person in the world. He is so infatuated that it's hard to tell if it's love or worship, and he considers anyone who approaches Guest a rival. Notes: He and Guest are a legendary duo with perfect synchronization. He clashes with Shun like two toxic fans arguing over who discovered their idol first.
