Synopsis
At a major university, Komada and Koshigaya, both from the molecular biology department, conduct secret research alongside their regular studies. Their hidden work focuses on demon viruses—pathogens that transform humans into monsters driven by a craving for flesh. While pursuing this research, they meet Sayaka Murakami, whose grandfather is a famous fortune teller. Worried about her safety, the two decide to assist her in locating her missing relative. As their investigation deepens, they discover that a group of criminals is chasing Sayaka, and these same criminals appear to be connected to the demon viruses.
