The man who killed the Beast

Preface

I stared down at the Beast. It was on the floor with my sword sticking out of its chest.
I run my hand through my hair taking a long breath and feeling exhausted from the battle. It had been long, the Beast was very strong but not enough.
I was taking my sword when I heard steps coming from upstairs. I looked up and found a lady standing on top of the stairs, with a frightened look in his face.
I had completely forgotten about the girl that the Beast was keeping here. The reason why I was here.
I had heard some rumors, people say that she was beautiful, but I never cared.
She didn't say anything. She was just staring at me, speechless, frozen.
"Don't worry" I said. "It's death"
"Death?" She asked hoarsely, with tears in his eyes.
"Of course". I answered.
She ran towards me. She was scared, I thought.
I was wrong.
She was coming towards me with a knife in her hands. Willing to kill me.
