The spaceship suffers a fierce attack, and Karen, along with her father, locks Tiliah and her younger brother Burn inside a small escape pod and launches them into space. "Just you two survive safely!" her father shouts. Evading pursuit from the Murder Empire's military, Karen heads toward ancient Earth. She believes that mastering this device will give them a chance to win. However, despite her father's objections, Karen insists on equipping it—yet due to her immature skills, she fails to achieve full synchronization. She continues training in secret. As the Empire's forces close in, Karen finally succeeds in achieving complete armor integration right before her father's eyes. Using the universe's strongest power, she annihilates the enemy and claims victory—but due to her lack of combat experience, she leaves an opening, and her father is captured. The Empire's leader brainwashes her father, promoting him as Professor Mad, a high-ranking officer who uses his expertise to enhance the biomechanical weapon Slash Diner. The full-scale hunt for Karen begins. Cornered by a fully powered enemy with all abilities perfected, Karen faces certain doom. Yet even as she resists surrender, she is gradually dominated—body and mind—along with her universe's strongest armor, and ultimately destroyed. [BAD END]
