Demon child 2

I blacked out. I lost. I may have died. That demon child. "Brother"

What was that. My eyes widened but I realised I was on a bed. A hospital bed. How did they find me inside the mountain. I heard the door creak. I looked and saw a nurse. Her mouth opened wide. She rushed out and I heard her saying " He's awake"

A doctor rushed in. And looked at me. Then the machines. I also looked but I didn't understand a thing.

"You're okay now, we found you unconcious at the mountain. Someone saw the battle and rushed to help you" He said " Your jaw was dislocated and your lungs and hand were also pierced. We created a replica to fill the gap but your heart rate decreased... a lot. So you'll be spending a month not going to battle" he paused

"The heart machine, to put it simply is recuperating your heart rate because for unknown reasons it's not going up." But who was it that said "Brother".

It can't be. Brother may be that demon... child.
