Reborn Into Dragon Ball: The System of Power(DROPPED)

A woman, Sierra Valeria, is involved in a robbery. She was a hostage during this robbery, and to prevent the robber from killing a young girl, she utilizes her martial arts abilities to stop the robber. She knew she may die, but she wouldn't let an innocent girl die on her watch. After quickly striking the guy holding her, she starts beating him like a drum, but during this beating, the gun the guy is holding goes off, the bullet piercing her chest. She looks at the gun, and then the guy, who is bloody. In a last ditch effort, she jumps forward, grabbing the gun, which goes of a few more times into her chest, but she has succeeded in pulling the gun from him. As she falls back, her consciousness fades, along with her strength. As she lays on the ground, choking on her own blood, a voice sounds in her head, "So, do you know about Dragon Ball? Because that's where you are going, to the Dragon Ball Universe as a saiyan. Good luck, and thank you for saving this little girl."
I think on the voice as I can no longer breath, and my eyes close involuntarily. 'What the hell,' I think. 'Is this a joke,' I think to myself, feeling my heart stop, and everything going completely numb. Thus, the death of Sierra Valeria was recorded, hailed as a hero, and never forgotten by this little girl, whom will eventually grow to be a pillar for justice, and the leader of security in a bright future. And now, a new saiyan life will begin...
