Master Crow, the leader of the global criminal organization Iron Claw, has been amassing stolen artworks from around the world and selling them at high prices on the black market. Makki Megumi, a member of a covert government special operations agency, infiltrates Master Crow's hideout to expose his conspiracy and gather evidence. However, she is defeated in battle by Benkei, a monstrous giant who embodies the organization's madness, and is captured by Master Crow. Thus begins Master Crow's twisted reign of domination. Subjected to extreme torture via high-voltage electric furnaces and assaulted by hordes of villains drawn to the female ninja Megumi's body, she struggles to endure the excruciating pain and attempts escape. Yet she is captured once again by Benkei and forced to submit to his brutal violation. The ordeal is merciless, even for a young woman like her. Screaming in agony, Megumi is compelled to accept Benkei's assault. Ultimately, she is forcibly subjugated and made into Master Crow's unwilling mistress.
