A promise is a promise (soul x oc)

Chapter 1

As I ran out of the house I felt of wind rush through my purple locks
"Let's do this, I promise papa"
I approached the DWMA
"Wow" i slowly approached the building
It was perfectly symmetrical, with every inch
"HEY NEW KID" Out of my peripheral vision I saw a kid with blue star shaped hair
"IM BLACK STAR LETS FIGHT"
"YOU WANNA GO, LETS GO" I screamed back
Knowing I'm prone to fighting and kind of a hothead I can't turn this fight down
"OK TSUBAKI LETS GO" I looked over at his weapon, she was beautiful
Tsubaki was tall with long black hair
"Black Star are you sure about this?" She questioned looking at me
"YES, AHHHHH" he screamed running towards me
I quickly summoned my bow
"AHHHH" I screamed back pulling my bow
Quickly aiming my bow I shot black star square in the chest
"OUCH TSUBAKI CHANGE FORM"
"On it" she replied turning into a chain scythe
He threw her at me, I quickly dodged running toward him
Suddenly I felt a surge of energy pulse throw my bow
"LETS GO" I shot a huge arrow filled with my soul energy
It hit spot on causing Black Star to drop Tsubaki
"Black Star!" She shouted running over to him
I panted
"I've never exerted that much soul wavelength before" I whispered to myself  
"Wow new kid you're good"
I chuckled as I walked over
"Piper Nixon" I put my hand out as Black Star returned my hand shake
"Black Star and this is my weapon Tsubaki" She smiled
I looked at the ground as my bow disappeared
"Woah, how do you do that? Are you a weapon or a Meister?"
"I'm a weapon, but I'm able to summon a bow with my soul wavelength, but it takes a lot out of me"
I noticed Tsubaki's eyes looking at my fatigued body
"THATS AWESOME, but not as cool and amazing as THE Black Star,
We should introduce you to the others, Come on Peter Piper"
"Peter piper?" I chuckled as we walked the stairs into the DWMA
