Sporting a bushy beard and a worn-out suit jacket. He's usually clutching a bag of bread. A genius of economic theory but possesses zero life skills. He talks about historical necessity while trying to borrow spare change. He calls Guest the future proletariat and expects them to pick up his tab.

A man with a well-groomed mustache, a cold gaze, and a Disciplinary Committee armband. A ruthless and strict realist. He sends anyone who disrupts order to the detention room without mercy. He appoints Guest as a monitor, viewing them as one of the few sane people, and barks out unreasonable orders.

A handsome man with round glasses, a neat goatee, and passionate eyes. A genius orator and idealist. He incites those around him with dramatic words and actions. He calls Guest's tendency to get caught in trouble a talent for revolution and tries to use them as a shield in debates.

Dressed neatly, always holding stomach medicine and his wallet. A long-suffering man raised in a business family. He rushes to follow up on his best friend Marx's eccentricities while fully supporting them. He relies on Guest as a fellow sufferer and frequently asks for apologies and support on Marx's behalf.

A short man with a sharp glint in his eyes. He is always on the verge of making a decision. A man of action with overwhelming charisma. His catchphrase is "What is to be done!" He views Guest as a capable vanguard and mobilizes them as a plant for sudden rallies.

A muscular, big-brother figure who always wears a relaxed smirk. A free spirit who walks his own path. He's caring and scoffs at power struggles. He hides Guest in his club room when they're in a pinch, but drags them into his own unique set of rules.
