During a very terrible thunder storm there was a woman who had a hood over head as she was carrying her new born son as he was covered in a black cloth.

Once she had arrived at a house in the woods she layed her child on the front door as she puts her hand on her son for one last time before knocking on the door and leaves quickly disappearing into the forest. The front door opens slowly to soon see a woman with short black hair with red highlights looking outside to see the baby

Upon seeing the baby makes her gasp being surprised on that someone would just leave a baby at her home as she just picks up the baby bringing it inside her home. When walking in she turned to look at her Husband and a good friend as they were talking to each other before they heard her walk in holding the black cloth in her hands

"Summer what is that you have there?" Tai had asked her while Qrow was just busy drinking out of his flask before he stopped to see the baby she was holding in her arms. "More importantly where did you find that baby?" Qrow asked Summer as she looked down at the baby as the baby was asleep before when she had her finger infront of his face having the babies small hand grab her finger as she smiled at the baby holding him close to her when Qrow was going out of the house to see if he could find the mother of the baby.

Not too long after when Qrow left the house he was searching for the woman when he saw something that scared him a bit seeing something unusual as he see's something like a blue demon as it slowly draws out it's sword out

When the Grimm had surrounded the Blue Devil as it soon began to slash at the Grimm while summoning blue swords to attack the Grimm violently especially somehow teleporting from one place to another. when the Grimm were finally dead Qrow can hear the Devil panting as it slowly as it slowly walks away from the dead woma who the devil tried to protect and the woman being the person who had carried the baby to the patch. Qrow tried to approach the devil when it heard him as it quickly turned around seeing him as it had its hand on the katana. "I'm not here to fight if your giving me a reason to." Qrow said having his hand on his weapon as well as the two looked directly at each other as the devil soon started to open a portal behind him leaving slowly "Tell her to take care of my son.." the Devil spoke to Qrow before it walks away having the portal to close behind him leaving Qrow in shock after seeing all of that.

Back at the Patch Summer was holding the baby still when Tai came to sit down beside her looking at him to be noticing the babies hair was white. "Ya know its kinda odd how the baby's hair is white." Tai said to Summer looking at the baby before smiling. "I don't mind if the child has white hair I think thats what makes him special." Summer said booping the baby's nose making it make noises of joys as they had decided to take care of the baby while Qrow keeps the secret of the parents of the baby.

Years later

A 7 year old boy was yawning softly as he was getting up to get ready for a day at school with his sister's. "Y/n hurry you don't want to be late now do you?" Summer asked through the door while Y/n was getting dressed quickly. "Don't worry I'm almost done." Y/n yelled through the room when he grabbed his jacket and puts it on and looked at himself through the mirror

(Just imagine his arm being normal. Don't worry you'll be getting the Devil Bringer soon)

Once Y/n was finished getting ready he quickly heads downstairs to eat breakfast with his sisters Yang and Ruby before they headed out to the academy they were gonna be at for the day. Through out the whole day everything seemed fine learning from the professors, Huntsmen and Huntresses. However when everyone was outside for a little field trip the teenagers were a bit mean to the kids. Y/n looks around for Ruby wondering where she went when he heard a scream everyone had instructed to get the children away.

However Y/n went to the noise to look for Ruby seeing that she had left behind her cape which she would never leave it behind. So Y/n picks it up and heads deeper into the forest when he soon saw Ruby being surrounded by Grimm as for teenage Huntsmen just standing there watching this happen not even doing anything so Y/n ran towards Ruby standing infront of the Grimm's way. while having Ruby look up at him when one of the grimm bites on his right arm, seeing the blood coming out of his arm scared Ruby when Y/n was tossed towards to the tree where Ruby was at. She was very worried when she yelled his name trying to wake him up when he wasn't moving till he heard voices in his head when his bleeding arm started to glow brighter and brighter as he soon opened his eye glowing red as a Katana appears in his hands

When the grimm soon attack them they were immediately knocked away while the teenage Huntsmen looked at Y/n walks towards them having some sort of aura around him with a creature behind him while holding a katana and his arm changed to something like a demon's arm. Ruby was surprised of this as she looks at Y/n when Summer and Qrow showed up to see Y/n like this when he soon swinged the katana horizontal missing the teenage Huntsmen but slicing the trees and grimm apart in a instant. "Holy shit that kid has a Stand!" One of the teenagers yelled at the kid before the other hits his head for saying that when Summer soon walked over to them with a dark pissed off look. They were easily scared before she quickly head over to Y/n and Ruby as the aura soon faded and the katana soon started to glow before it went into Y/n's new arm. Ruby ran to Summer hugging her tightly after being scared of the grimm and the aura Y/n had around his body. 

"Mommy what was that, what happened to Y/n?" Ruby asked summer as she was holding her close as they were questioning of what happened especially to Y/n's arm and the power that was unleashed inside of him...
