Revenge

As the demon began to solidify inside the magic circle, she grabbed my hand.

"Wait, is this really worth it? I get you want to know who killed your parents, but selling part of your soul like this to get it, isn't that going too far?"

I considered it.

"Maybe you're right."

The demon formed in the circle. I made up my mind.

"I offer part of my soul for the being or beings directly responsible for my parents death to be killed."

The demon laughed and snapped his fingers. My soul became lighter, as she died next to me.
