Secrets and answers (Rin okumura x Oc)

prologue

"What wrong daddy..."
I walked closer to him afraid, scared, and confused. I walked closer to him just wanting to touch him. But as I touched him the flames grew wider.
Ouch!
I stepped backwards and ran away, but he grabbed me on my waist. The burn marks grew wider and wider each second. I held my pain and finally let go of me. Tears sprouted into my eyes, for I can't move. I ran to mom's room/dad's and quickly closed the door.
"Come on mommy wake up dad turned blue!" I kept shaking her until she finally woke up. "What's wrong, Saki? Where's dad?"
Her eyes grown in terror as she saw my burn marks right on my waist. She struggled to touch me as if I was poison. She faced forward to dad who was right in front of the door. With the sword.
Mom pushed me into the basement "no matter what happens, please stay safe..." She held out her pinky and smiled "promise...." I held out my pinky "promise."
I don't get it why mom-?
My mind went back to reality which I wish I wasn't though after what happened. Blood splattered on my face as I slowly touched it. Terror crept all over me as I looked up.
"MOM!"
I raced out of the basement and touched her pale looking face. She touched my hand and put something in it.....
A single white light.
"Use this to keep-"
please no.....
"Answer mommy....please don't go.." Tears kept coming out and looked at my father.
"DAD, SHE'S YOUR WIFE HOW COULD YOU DO THIS TO HER!!!" Before I knew it he took the sword and.........
Killed hisself.
Red flames came out of the sword and the blue flames disappearing. "I rather drop dead than to kill my own daughter!"
But at the same time there was another voice.
"Just wait you can't keep her long forever..."
And just like that, he drop to the ground, just like that. Both flames died out, while the sword is in the pocket-thingy. I picked it up, grabbed my umbrella, and left. I looked at my watch 1:24 a.m. I just sat there, yet a woman stand right in front of me. "Oh dear...come with me." I didn't hesitate one bit, I mean who would like to stay out in a cold, windy, wet, with demons outside. And that how I first want to become an exorcist.
But they are some secrets and answers left in this ugly but beautiful world.
