My Death Angel(UFSans X FemaleReader)

I am an experiment. I have no friends. I live with my creator in the forest right below Mt. Ebott. Everything I touch dies but a collar prevents me to do so. I met death when I was young right after my creator died. But after a few years, he left me abandoned, unwanted in my house in the middle of the forest. Until I saw a child running up the mountain. I tried to stop the child before they jump. I look at them and approach them. They didn't run, I was shocked. They look up and smile at me. Then they fell back. I grab them and pulled them into a hug and fell with them.

What awaits them down there? Will they ever get out alive? Will the monsters fear your power? Will you find your soul mate down there? Will you find the family you ever hope for? Will humans finally accept you and the monsters? Will you finally meet death again?

Will all these questions be answered?
