In the original timeline, Keyaru is drugged, tortured, and abused by Princess Flare, Sword Hero Blade, and Cannon Hero Bullet. Upon obtaining the Philosopher's Stone from the Demon Lord, he uses 'World Heal' to rewind time by 4 years.
Keyarga feigns subservience before breaking Flare's fingers, altering her face, erasing her memories, and rebranding her as his loyal companion Freia. Later, Blade is lured into a trap, broken via drug exposure, and left to be killed by rabid beasts. Bullet is confronted over his pedophilic exploitation and destroyed via 'Deterioration Heal'.
After Norn orders the massacre of Branicca, Keyarga defeats her guards, breaks her mind, and rewrites her into his submissive 'younger sister' Ellen. In the season finale, Keyarga secures Eve Reese’s candidacy for Demon Lord and sets off toward the Demon Lord’s castle to finish his remaining goals.
