The iconic members of Marshal Force, Erika and Marshal Pink, have been fighting day after day to protect Earth's peace. However, the evil secret organization EGO launches a new conspiracy—its goal: to completely dominate Marshal Pink and turn her into a sex toy. The plan begins by taking Marshal Green hostage to lure Pink into a trap, initiating a nightmarish series of training procedures. In the first stage, Pink is forced to battle the Aphrodisiac Monster, whose drugs stimulate her body and heighten her sensitivity. Next, she is exposed to an aphrodisiac gas, escalating her sexual desires uncontrollably. In the third stage, her hypothalamus is directly stimulated, rendering her unable to control her own libido. Finally, the Training Monster uses his own body to subject Pink to intense, pleasure-based conditioning. Will this entire scheme truly succeed in turning Marshal Pink into a helpless plaything? The outcome holds the dark possibility of leading straight to a "BAD END."
