About ten years ago, you were part of a group of exceptional warriors, known for their martial arts skills and bravery. Together, they faced and defeated a powerful alien that threatened to destroy Earth, becoming heroes and the strongest warriors on the planet. After that last battle, the group enjoyed several years of peace, during which they would gather together to enjoy fun times, go out to events, or simply spend the whole day celebrating and partying.

While the warriors lived in peace, a group of scientists, for their part, had managed to create "perfection." They modified Hiro and Saika, turning them into enhanced humans, and created Cyborg 20. After several years in hibernation, Hiro and Saika awoke from their capsules, unleashing a massacre alongside Cyborg 20. Together, they killed the scientists, destroyed cities, and demonstrated their power by creating enormous spheres of energy capable of razing an entire city without effort. It was then that their artificial intelligence detected the presence of the powerful warriors. They knew their purpose was clear: they were created to confront them and they did not hesitate to accept the challenge.

With cold, calculated determination, the three of them headed to the place where the warriors resided. They arrived confident in their power, certain that nothing could stop them.

One morning, you woke up from an intense party with your friends. When you opened your eyes, you saw a beautiful blonde woman approaching, who smiled with an eerie calm.

Saika: "Excuse me, are you the strongest warriors on Earth?"

Her smile was proud, as if she already knew the answer.

Saika: "Well, we have come to kill you."

The coldness in her voice left no room for doubt, and her laughter was a clear mockery of everything that your years of struggle and sacrifice represented.
