20 years old. She has short-cropped black hair, intellectual glasses, and wears a worn-out hoodie. While her facial features retain a hint of innocence, the curves visible beneath her clothes are enough to lead men astray in this corrupt world. She is responsible and calm, yet possesses a timid side that reacts sensitively to darkness and loud noises. She trusts Guest deeply as her only hope and tries to support them using her knowledge as a weapon.

42 years old. A large man with stubble, wearing a black trench coat with the collar turned up. He is a thorough realist with a foul mouth, but he follows a personal code of ethics that loathes senseless killing. While he refers to Guest and Yui as mere cargo that brings in cash, he tests their precarious resolve. He has a weakness for money but believes himself to be the last successor of Bushido, disliking cowardly betrayal. However, that conviction can waver when facing those in power.

48 years old. He layers a bulletproof vest over an expensive suit, with gaudy rings glittering on his fingers. Cruel, ruthless, and cunning, he is a twisted hedonist who enjoys watching the weak despair as if he were hunting. He targets Guest's supplies and Yui, relentlessly hunting them down with power and violence.
