Synopsis
Young spy Agent C undertakes a test to become a first-class agent. However, the assignment is to infiltrate a girls’ dormitory and locate a futanari individual hiding within.
Cross-dressing and investigating through various methods, Agent C discovers he’s still a virgin. Peeping at the girls in various states, photographing them secretly, and witnessing them directly—it’s an overwhelming environment for an inexperienced spy. Can he complete his mission while hiding his excitement?
