Newly appointed Ranger Pink, Momoko Matsuyama, finished her first battle but was unable to be of use. Seeking strength, she accepted a proposal to have a "cell activation device" installed, which would grant her power similar to that of the previous Pink. After the vaginal implantation surgery, Momoko headed alone into enemy territory, but was defeated by a monster and taken away. In reality, this was an infiltration operation to locate the enemy's hideout, but contrary to the plan, her allies were taken hostage, and Momoko was forced to obey the enemy. After undergoing a lewd body inspection, the "cell activation device" inside her vagina was modified, turning her into a nymphomaniac. In the end, she was violated by the enemy boss, Schwarzenkreuz, and turned into a sex toy... [BAD END]
