I've Become the Sister of Himiko Toga
In a dark room a four year old girl wakes up and groans in pain. After a while she starts to look around. "What? Where am I? Why do I hurt so much?", she asks barely coherent. She then looks over her body and sees bruises all over her. "Why am I beat up? I don't understa-", she then hears another groan next to her. she looks over and sees a girl laying on her side next to her.
The girl is in the same state that she is, noticing this the first girl rolls the second on her back. The moonlight hits the second girls face and then it all comes back to the first girl, "Himiko!", she quietly exclaimed. "Wait if she's Himiko then...", memories start to flood her mind. This wasn't her first life no this is the second that she can remember.
Her life before she was a 24 year old guy. He was driving home from work on the highway in his SUV when a car cuts in front of him. He turned to the left to try to dodge it, but the car changed in that direction as well, so he curses and cuts back to the right. In his haste he turns to hard lifting the left wheels off the ground. An 18 wheeler behind him couldn't stop in time and pushed the guys car over on the driver's side crushing him.
He heard a voice that said, "Well that was unexpected". "what do you mean that was un-expected?" he replies back. "You dieing before your time", the voice says plainly. "*sigh* Ok so what's going to happen now?", the man asked in irritation. "You don't seem to be angry about it", the voice said a little shocked. "I just know there's nothing I can do about it", the man says dejectedly. "Pragmatic one I see, so what would you like to do now reincarnate or haunt the guy who got you killed?", the voice inquired. "Hmm, let's see. They both sound fun, but reincarnation it will be. Reincarnate me in to *My Hero Academia*, make me into Himiko Toga's twin sister, and give me a similar 'Quirk' as well." the man states.
"Why sister and not brother?", the voice inquired. The man responds, "She will bond with me better that way and I don't care what sex I am really." The voice thinks about it, "Hmm, ok I'll give you a 'Quirk' similar to vampirism except you're not weak to sunlight, you'll age until you're 21, and you can only drink blood." The man replies, "Sounds good I can handle it from here then."
Her thoughts are interrupted by Himiko, "Tsukiko it hurts," she sobs. Tsukiko lifts her sister up and hugs her, "I know it hurts me too." After awhile the pain settles, Tsukiko asks Himiko, "Hi-chan do you want to run away?" Himiko thinks for a minute, "I don't know if I can," she says shakily. "They almost killed us this time because of us having to drink blood and I doubt it will be the last. I think we can do better on our own," Tsukiko says wearily. Himiko thinks again and sighs, "You're probably right sis, let's go." Like that in the dead of night they run off to find a safer place.
