Romero wa Sekai wo Sukuwanai

A young man remains in a shopping mall six months after the world ended, living with his manager as everyone else left in search of salvation at the center. During a routine check, he encounters a girl named "Romero," the first living person he has seen in a long time. She is not searching for food, water, or rescue, but instead for a movie. She expresses indifference toward humanity, suggesting that since the world is already in chaos, it might as well be enjoyed with a film.
