Persephone_Riddle
Two girls, Persephone Riddle and Kei Yuxria were murdered together, as their not do friendly rivalry got them in trouble with a serial killer. They thought they could move one, but nope! Fate decided that they could rather; A, spend 100 years in Purgatory, with each other, or B, be reborn and bring justice upon the serial killer. Not knowing what to expect, they of course chose option B, thinking that it was the best way to get away from each other.
But Fate was always a trickster.
