One shot

The Straw Hats are defeated and Law's soul gets dragged down to hell as he dies giving his life to Doflamingo, who turns immortal, just like he had always wanted, thanks to the deal made with the devil through the devil fruit Ope Ope no Mi.
So now Law must remain a slave for the god of the underworld, mostly mistaken as a male, known as (Y/N) 'The Queen of Hell'.
Hmm... What shall she do with her new toy?
