The new Ranger Pink leaving Nebraska was once a former combatant belonging to the evil organization Satan Cross. Before undergoing brain surgery, she defected from the group and has since carried the tragic past in silence. Driven solely by her desire for revenge against Satan Cross, she takes on a new battle. However, a mysterious power resides within her body—a presence known as Little Demon implanted deep within her most intimate area. This device vibrates unpredictably, tempting her toward evil. The other four rangers, unaware of her past, begin to distrust her. As the battle intensifies, in order to stay one step ahead of Perfect Devil, Little Demon activates once again. As a result, all five are quickly overwhelmed. Captured by Satan Cross, Ranger Pink falls before her comrades, her secret as a former combatant exposed. The other rangers turn on her, blaming her fiercely, while enemy soldiers beat her down. Pink is attacked by Perfect Devil, left battered and broken, then assaulted by her own teammates. Ultimately, the other four are imprisoned. What will become of the rangers' fate...!?
