When we got to the infirmary he put me down

"You need to stay here until you heal"kid said

I heard sounds from outside

"(Y/n)! It's a dark guild!"Wendy said

"What how did they get here"I said

"I don't know but they knocked out natsu and gray"Wendy said

"Okay"I said getting up

"Where are you going"soul asked

"Where the fight is"I said
I started to run

*time skip in battle field*

"Let's dot his"I said as a sword appeared in my hand

There guild was judge and I could sense tons of power probably more than my own

"Wendy are you ready"I said

"Yeah but we only practiced this once and the last time you did it you passed out "she said

"It's okay I'll be fine"I said

She cast a power increase spell on me and one to make my defense better and faster

I started to combine all of my slayer Magic's it hurt like hell

"Are you sure your Okay"Wendy said

"Yup"I lied

Soon it was finished

"Celestial god slayer star rain"I said as half there guild was whipped out

"Moon demon slayer swords"I said as two swords appeared in my hands

One of There strongest guild members ran up to me with a giant sword

I blocked there attack and sliced there side with my other sword

More of them kept coming and I was running low on magic

"I can help you if you let me"I heard seilah say to me

In that moment I didn't have a chance

"Okay"I said

I felt extreme power flow into me my eyes turned completely black with a moon in the middle as pure magic surrounded me her mark appeared on my forehead and I grew her horns on the sides of my head and my hair grew all the way to my feet.

I ran at them and took them all out at once

I took out almost all There troops

More of them came over and over

"Are you Okay (y/n) what happened"Wendy said

"I'm fine let's just get this done "I said
Seilah was now with me in my mind every breath I took she did the same we worked together and I realized she wasn't such a bad person even thought she is a demon

"Breath (y/n) if you don't calm down you can suffer large side affects "she said

I breathed in and out
"Good now focus your power on the enemy"she said

I held two swords in my hands calmly as I charged my magic in them as they glowed black

"Good now attack with that energy using demon slayer magic"she said to me

"Moon Demon slayer secret art(if that exists if not I made it up) DEATH ECLIPSE!"I yelled as tons of power came from my swords sending pure darkness at my enemy's and killing them from the inside and outside

Soon they were all dead

"Very good (y/n)"she said

The mark on my forehead dissapeared and so did the horns

My eyes went back to normal and so did my hair

"I'll be waiting"she said

Soon I was back to normal and covered with injuries

I fell to the ground and passed out
