Demon slayer (AU)

Chapter 1

I opened my eyes and I saw a man with red eyes. He was in a black suit with a white hat on. He held his hand out to help me up. I reached out and took his hand.
Then I heard a faded name being called, "Mika! Mika! Mika Hanako, Wake up!" yelled the voice over and over. I opened my eyes and sat up breathing kinda hard.
I saw Aoi looking at me crazy, "Mika! You sleep in again, and did you have the dream again?" she said, putting my food down next to me.
I look at the food then her, "Yes. I did. Anyways, did you make the food that doesn't make me sick?" I ask.
Aoi nodded, "The master needs you and wants to talk to you. Also you need not to move so much. You hurt yourself in your last fight."
I stand up and put on my outfit. I looked at my haori and took a breath.
Aoi looked at me, "Is something wrong? I washed it from your last fight. I must say, it had a lot of blood on it Mika."
I smiled at my dumb idea I have, "Hey Aoi. I am gonna go and join the Final Selection. It sounds fun to do, you know? And I can see the new kids that are gonna pass."
Aoi looked at me shocked, "Mika Hanako! You can't do that! Master wouldn't allow it and you have a job to do. You're so careless, you know that right? And you might die out there Mika! And no one can save you if you do die and all those new kids are not even trained!" yelled Aoi trying to talk me out of it.
I smiled and laughed while putting on my haori, "Well Aoi." I said while grabbing a rice ball, "I am just insane like that!" I yelled while running out of the butterfly Mansion. I ran to the master house and stopped because shinobu was in front of me.
I look at her, "shinobu. How have you been? Weather been amazing hasn't it?" I ask, trying to act like I wasn't up to something.
Shinobu smiled at me, "Now. Where are you going, Mika?" She asked while closing her eyes.
I took a breath and looked away, "I am going to master. Aoi said that the master needs to see me." I said while walking past Shinobu.
Shinobu put her hand on my shoulder, "Mika. If you did something to worry Aoi and the others. I will hurt you, Mika."

I took a breath and threw her hand off me, "Shinobu. What I do and don't do isn't none of y'all business and Aoi shouldn't always be worried about me." I said, while walking off to the master.

    I walk into the master house, "Master? Master?" I ask looking around.
Amane walked up to me, "Miss Hanako. He just coming out to talk to you. Why did you not knock? It is bad to not knock, Miss Hanako."
I nodded and felt bad, "I am sorry. Mrs. Amane, I learn to knock. I promise." I smiled at her and rubbed my head.
Amane smiled and nodded. Master walked out and sat down. He offered me to sit in front of him, "Mika Hanako. Please sit down." he said smiling.
I smiled lightly at the master and sat down, "So Aoi told me you needed to see me. Why is that? And I want to ask you something."

He pulled out a paper, "well. Sometimes you will go missing at night where your crow can't even find you. The people in the Butterfly Mansion are becoming worried for you and want to know why you go out at night."
I look at the paper and let out a little giggle, "Master. Don't you worry and they don't have to either. When I can't sleep I go outside and go to this river that is close by. It reminds me of when my parents were alive. I am sorry if I worried everyone and you. My mother would sing me a song by a river when the moon is staring back at the river. Please forgive me."
The master nodded and closed his eyes, "Now what did you want to ask me, Miss Hanako?"
I smiled really big, "I want to know if I can go into the final selection with all the other new demon slayer members that might make it."
Master looked at me a little shocked, "Why is this Mika? You have already passed the final selection with amazing skills."

I took a breath, "well. I just thought why not, and it be so much fun. I hadn't have many jobs to do and I will be free. I promise, I won't do anything dumb and I won't help anyone get into it when they don't have the full chance of getting into it, master. Just please." The master opened his eyes and thought for a minute. He nodded and smiled, "Okay. I allow it, Miss Hanako. Please don't die." I stood up and bowed down to the master, "I promise you. I will not. None of those demons can beat me!"   

I walk into my room and put on my training clothes. I went outside and sat down. I looked up at the moon and took a deep breath. I need to go to the Infinity castle or else Muzan will think I am dead or something and get the weird one-eyed lady to find me, I said to myself. I took my training clothes off and under it was my demon outfit with the sun on it with a full moon on it. I was wearing shorts that were yellow with light blue lines. And a shirt that went to the waist which was the colors of sky if it was painted yellow, orange, and pink. It had the full moon on it. The front of the shirt was sideboob showing type of shirt.  it covered my neck. I also was wearing a belt with clouds and a sun on it. It was a gift from my father. I was wearing my mother's hairpin which was a red spider lily. My shoes were like Kanado shoes. She had some other shoes like them and she let me have them. I ran to the place where the Infinity Castle is. As soon as I put my foot down on the floor, I was in front of Muzan and the uppermoons. I am guessing Nakime teleported me to them as soon as she heard me.

Doma looked at me, "Emika! How have you been?" asked Doma, trying to be friendly.
I looked at Doma and smiled, "Doma. Don't act like you really do like me. I know you don't." I said, while my eyes changed to blue and the other one stayed green.
Doma laughed, "Your eyes don't match anything on you. Neither does your hair. Oh! Did you change it again? Did lord Muzan say you can?" He asks while grinning.
I let my hair out of my bun and it fell down to my waist. It was light green all down but to the tips was light blue, "Just so you know Doma. This is my real color. When I was human, idiot. And you know Muzan lets me do whatever I please."
