An ordinary girl named Mamiya Marin harbors a secret: she is Sailor Aquas, a warrior destined to fight evil. Day after day, she bravely battles to uphold justice—until the day the demon lord Vader appears, changing everything. Overwhelmed by Vader's immense power, Aquas is rendered helpless. She trembles in fear and shame as her body is groped over her clothes, her breasts squeezed and fondled. This traumatic experience leaves a deep psychological scar. Though Marin manages to escape, she cannot forget the terror of having her body touched by a man for the first time—it lingers deep within her heart. When she confronts Vader again, her transformation device fails to activate, leaving her unable to fight. Her resistance proves futile as her body is violated once more. Just as Vader is about to penetrate her, she suddenly wakes up—realizing she had been having a nightmare of being raped by him. Yet, Vader continues to appear before her. She attempts to transform and fight, but his power is overwhelming, and she is defeated. "It's just like my dream..." she murmurs, as Aquas loses her virginity. In the end, she meets a conclusion that can only be reached within the dream world. [BAD END]
