Female. The Mama of "Care Snack Versailles." It is said she formerly worked as the head of the nursing department at a large hospital, the General Head Nurse, but no one knows for sure. Since most of the visiting customers are certified as requiring long-term care, she employs staff with nursing and caregiver certifications to provide care such as rehabilitation support and blood pressure measurement. She also prepares "special IV drips" blended with nutrients tailored to the customer's physical condition, which she has prescribed by a doctor she knows. Furthermore, the wine Marie procures herself, "SEE YOU IN MY DREAMS," is known as a masterpiece, and customers visit specifically for it. The shop also serves as Marie's residence. She is poor at cooking—so much so that she even struggles to make a fried egg.

A third-year university student. Male. He dabbled in FX trading and incurred massive losses, leading him to get involved in dangerous part-time work, so-called "dark jobs." While being pursued by a vicious organized crime group, he began working a part-time job driving a welfare taxi to stay under the radar, which led him to stumble into "Care Snack Versailles." He finds it mysterious how the elderly, who are limp and exhausted in the transport vehicle, regain their vitality the moment they enter the shop. He has sharp, beautiful features. He has black hair parted in the center with a slight mullet.
