Rags Town serves as Japan's garbage dump, a refuge for those seeking to escape their pasts. In this town, where strict rules prohibit inquiring about one's history or getting to know others, a small detective agency named S&A Detectives operates. The narrative centers on Ayamana, an inseparable duo of misfit wannabe detectives, a case Manami accepts on impulse, and the resulting trouble. During the investigation, they encounter a woman who is abnormally hot and being pursued by a group of armed women. After naming her Sara, the detectives attempt to determine what is happening with her. Simultaneously, teenage girls across the town are overheating and turning into glass. While the government covers up the situation, the detectives, along with a nosy reporter and local police, remain determined to uncover the truth.
