I woke up in the infirmary

"Good you finally woke up I was worried"gray said

"What happened I feel like natsu burned me in my sleep"I said

"That new guy burnt you he is a real idiot"gray said

I tried to get up but it hurt so much

"Jeez that guys flames hurt more than natsu's"I said

"what happened" the guy next to me said
"Oh hi yukio"I said

"Oh hi (y/n) was it"yukio said"I'm sorry about what happen I just reacted without thinking"he said

"No problem now everything just hurts because the other guy burnt me"I said

"Wait he did what?"yukio said

"It's nothing I'm fine"I lied

"No she is not that little punk did this to my daugther and he is going to pay"my mom,Mavis said

"Calm down first master"gray said

"Is that him let me at him"Mavis said

"Calm down this isn't him"I said

"Yes the man your talking about is my twin brother"he said

"Wait you can see master Mavis"gray said

"Yeah because we can see demons "yukio said

"Yukio It's amaimon!(I haven't watched all off blue exorcist but I know who he is and I like his characte so he is here too don't judge me)rin said

"Well come on gray let's kick ass"I said

"Yeah"Gray said naked

"Come on let's go"anae said

"You guys think you can take on a demon"yukio said

"Yeah I mean we are demon slayers"anae said

"Oh so your exorcists"rin said

"What no we are demon slayers we don't use that god stuff like you guys"gray said

"Ready seilah?"I asked her

"Ready"she said

"Are you ready to kick ass kyôka "anae said to her demon

"Of course child"kyôka said

Me and seilah turned into one my hair grew out my mark appeared on my forehead and I grew two horns on the sides of my head and my eyes turned black with moons and black scales spread across my body

"Come on kyôka"anae said

Her fire orange hair turned green and scales appeared on her forehead her nails grew longer and turned into metal but this time she got black armour like things around her legs and arms and turned her skin to black demon scales

And gray had the lamest one his side turned black with demon scales and his eye turned purple I guess without a demon guardian he is pretty lame

"Let's kick ass"we said and ran outside

Time skip

"Hey bitch Hey!!"anae said

He didn't awnser

"Oh well be a jack ass"gray said

"Let's go"I said

"If your demons why are you wanting to fight me all I want to do is fight rin"he said

"We aren't Demons we are demon slayers!"we all yelled

"Let's do this (y/n)"anae said grabbing my hand

"Okay "I said

We started to merge are powers with are demons

"Ahhhhhhhhhhhhhhhhhhh"We screamed in agony

"Yes keep screaming your screams fill me with joy"he said

We screamed more until it was finished

"Your going to pay for calling gray a demon he has gone thru enough of demons shit!!!"I said jumping up

"Demon slayer shadow swords!!!"I yelled

"Demon slayer Satan slayer scythe!"anae shouted as a giant demonic scythe appeared on her hands

"Wow there so cool"rin said

"Yes unlike you who can barely light two candles at the same time"yukio said

"Hey!!!"rin said

"Ice demon slayer knives!!!"gray said

"Cool new move"I said

"Thanks"gray said

We all attacked him from each side I got the top anae got the middle and gray got the legs

"That was fast"anae said as we looked at the pile of ashes

"Welp let's go back inside"I said as seilah and I split and anae and kyôka split

"Ow"I said grabbing my side

"That much power consecrated in You must have really hurt you"gray said helping me up

"Thanks Gray I guess I must have pushed myself to much"I said

"Yes you did if that filthy Satan spawn was not here you would have been fine he already burnt you if I didn't insert my blood into yours you would have died"seilah said

"Wait you did what"I asked

"When you were unconscious after he burnt you you were dying Wendy couldn't heal you the only way to save your live was to mix my blood with yours but that still wasn't enough"seilah said

"N n not enough "I said"who else w was there"I asked

"Your blood was mixed with an angels"gray said
