The original owner of this body, who brought the system to this world eight years ago, died while fighting an enemy one day. Before he died, he recalled the promise he made to his mother, "I will definitely bring my sister back!" And felt disgusted with his own powerlessness. Make an agreement with the system, and if the agreement is fulfilled, you will sacrifice your soul and body. Now that I have the system and the soul of the original owner in my mind, I panic. Very OOC, purely for my own entertainment.
Intention: No matter where I am, I can be single based on my ability!
