Welcome To Night Raid

Chapter one: The capital

"Wow never seen a place this huge before!" You said once you were near the capital. You headed into a library so you would know the history of the place a bit more, wouldn't want to go to a place while knowing nothing about it.
The place wasn't filled with people. You saw about 10-19 people in the library. You were a bit curios about the 2 hooded people but you ignored them not wanting to get in there business. They were watching you for some reason it gave you the chills.
You grabbed a book about the history of the place. Right when you flipped to the next page you felt something on your shoulder. "Can you come with us for a minute" It was one of the hooded people, A buff man with a deep voice."U-um sorry but I'm trying to rea-" The man cut you off and dragged you into the back. He opened the back exit and threw you into the wall outside.
' Yup I'm dead, Good bye life I'm gonna die ' you thought and closed your eyes. You heard footsteps and what you think might be a weapon going threw flesh. You opened your eyes and saw the hooded man on the floor with claw marks on his clothes. You looked up and saw a girl with yellow hair and was barely even wearing clothes. "Um what j-just" you couldn't even talk, you just witness murder right in front of you.
"Oh hello there!" The girl said. You backed up a bit but she walked closer to you and grabbed your arm. "Let go of m-" she laughed while you were talking. "Don't get scared its not like I'm going to hurt you!" She said with a smile on her face. "I'm leone by the way your name?"
"...its [y/n]" you said and tried to get your arm out of her grip. Didn't work. She pulled you out of the conner. She let go of your arm, it was all red. "Hey can you fight?" She asked.
"..I guess so why" you responded
"You know about the imperial arms right, and the trump cards?" She ask you.
"Yes they are the most powerful weapons created from what I heard, and the trump card also works the same way" you said.
"Follow me I wanna show you something" she said and grabbed your arm again and pulled you with her.
"W-Where are we going?!" You ask and ran with her so your arm doesn't rip off.
"Heh..I wanna see how you fight" she said.
