Sister Agatha Double



"Double must've been a monstrous, transforming creature who works under the Trinity. Was she responsible for ensuring that the Skull Heart would fall into the 'right' hands, or should I say the 'wrong hands' so she can manipulate some horrifying events, all according to the goddesses' wills?"

--Su Ji-Hoon, Doubled in Fear
