Hearts and Minds Intertwined || Zeldris X Reader

Long ago, Y/N was a demon that served as Zeldris's guard. Except, she wasn't anything like others thought her to be. She was bubbly and cheerful, yet she also had enviable loyalty.

Many of the Demon Race despised her. Ever since the Demon Kings sons were young children, Zeldris and Y/N were always together. Y/N's mother was an esteemed knight that spent her days teaching her daughter so that she may take her place as Zeldris's protector.

Despite that, the two always seemed to have an unbreakable bond. In the end, it resulted in her death....

Many years later, she was reincarnated as a human girl, a skilled thief to be exact. Ever since she was a child, there was always a voice in her head that comforted her. She never knew it's name, but it told of a promise that they would one day meet.
