Kokoro, a rookie public safety investigator, is full of a sense of justice but prone to making mistakes. She teams up with Yamada, a cold and unpolished ace investigator, to infiltrate the dangerous organization known as "Crimson Claw." From her very first mission, Kokoro is late and makes a series of blunders. Her catsuit makes her infiltration obvious, and she spectacularly falls while wearing flip-flops, which she chose for ease of movement. To top it off, she forgets to load her gun and leaves her phone on silent mode. Due to her continuous failures, she is easily captured by the organization's subordinates. The boss, Takano, finds Kokoro's pathetic pleas for her life amusing and decides to toy with her, turning her into the organization's plaything. Pushed to her limits, Kokoro gradually loses her reason as she is overwhelmed by pleasure. Surrounded by the organization's men, she is subjected to aphrodisiacs and toys, used, brought to climax, and covered in their fluids. What will become of her fate, and how will this story end?
