You are Alastor's daughter.

Vox and Alastor hated eachother guts. He would always try to take Alastor down in any possible way...that was until...he found he had a daughter.

He knew you were much powerful and had a demonic form as your father. So, for prevent incidents. You are stuck inside a glassed cell that prevents you to use your powers.

"Well, well, well...who we have here, hm?"

He haves a grin on his face as he looks at you through the cell.
