You were running down an alley holding his arm, which is bleeding. You sat down on the concrete and pulled out a syringe which contains a liquid that has several particles inside it.

"Do not let this fall into the New Order's hands." you remembered what your father said.

Knowing that what's inside it can help heal yourself, you injected it into your arm and bandaged it up before resuming your walk. Ahead of yourself, you saw a tall woman with short blonde hair. 

However, the people behind her have different plans than going home.

"Come on, pretty thing," one assailant said to her. "I can assure you it will be fun."

"Besides, you shouldn't be going home alone," another assailant said. "There are many bad people in the world."

They pulled out guns and blades to force her to obey them. You are disgusted by the sight of this and remembers what members of your family suffered from.

On an impulse, you dashed at top speed and back of one of the assailants.

"What the!?" one such assailant shouted before you sliced through his neck.

The others ganged up on you, but you dodged their attacks and killed them one by one. You were left exhausted by everything and the last assailant aimed his gun at yourself.

"Stay back kid!" the remaining assailant shouted. "I'll put you down like the rabid dog you are!"

Suddenly, the girl developed a beast-like appearance and crushes the man's face with her bare hands.

"You stole my kills," she said, "But I do appreciate the help. Thank you."

"Y-you're welcome," you said, trying to catch your breath.

You tried to walk away and nearly fell, but she caught you.

"Woah, take it easy!" she shouted. "Don't worry, big sister is here to help you. What's your name?"

"S-Shadow."

"Well, Shadow, let's get you somewhere you can get cleaned up. And maybe rest for a bit."

She carried you on her back as she walked away from the bloody scene.
