Earth had maintained peace thanks to the efforts of sisters Sisutan and Aurora—until the evil scientist Dr. Gerry unleashed a new threat through his sinister plot. The new monstrous entities he created, God Ankuraimu and the ravenous Oni Slum, emerged as dire dangers to the planet. Dr. Gerry developed a new weapon: a multidimensional spatial device that allowed him to control living beings from vast distances. Using this power, he began tormenting Aurora to fulfill his dark ambitions. However, Dr. Gerry's true objective was not merely to inflict suffering on Aurora. Worried for her sister, Sisutan rushed out from headquarters to protect Aurora, only to be ensnared in Dr. Gerry's scheme. Deceived by Oni Slum, Sisutan fell into a trap and was captured. Fearing for her sister's safety, Aurora set out to find her—but was confronted by the monstrous God Ankuraimu. Overwhelmed by its immense power, she collapsed unconscious. When Aurora awoke, she found herself imprisoned in Dr. Gerry's base. Completely restrained, she was subjected to relentless assaults, enduring unbearable agony as she wept and screamed in despair.
