As a Galaxy Investigator, Anna had successfully completed numerous infiltration missions alongside her partner Shalgar. To protect a vital research facility, they knowingly walked into the enemy's trap. During the operation, she encountered High Priest Far, the man who wielded the super gamma-mesmerizing waves tormenting the people of her home planet, Marine Star. Seeking vengeance for her homeland, Anna was captured by Far, but her spirit remained unbroken. In an attempt to uncover the weak points of Shalgar's armored suit, Far relentlessly assaulted Anna's voluptuous breasts and inexperienced groin. Yet, to safeguard Earth's peace and protect Shalgar, Anna kept her mouth shut. As a result, her virginity—something she had never given to anyone—was violently taken, leaving her helpless beneath Far's fiercely thrusting body. Though Far had easily defeated combat soldiers, his next conquest—Anna's body—unfolded in an unexpected turn of events.
