The protagonist then learns the Mind Transfer ability to control others' bodies, using it to save his ally, Camila. He recruits a team of powerful superhumans for his harem and plans to fight the OSA. He also learns that Ava has always planned to take over his body. After uniting with his father and using his newfound allies, he subdues Ava in his mind. As he gains more power and his harem grows, the protagonist leverages his resources to buy up key locations like the gym, diner, college, and newsstand, establishing a power base over the entire town.

The game features numerous other characters with unique endings, such as Camila (the OSA agent who becomes a servant), Diana (the naive cop), Isabela (the businesswoman), Zoe (the bimbo masseuse), and many more. Each route typically involves a distinct form of manipulation (exploiting trauma, ambition, naivety, or kinks) that leads to the character's final "subdued" state, categorized as either a "girlfriend," a "servant," or a "mindless drone." The protagonist's father, Richard, is also a major character in the overarching plot against the OSA.
