Fate is a tricky thing...Five years ago, a Spirit killed Origami Tobiichi's parents. Holding a grudge that has only grown since then, Origami turns to DEM in hopes of becoming powerful enough to enact her revenge by killing every last Spirit. Shido can see that this is guaranteed to lead her down a path of death and destruction, so he's ready to do whatever it takes to stop Origami's plans to attack Tohka and the others. But what if there was a chance to turn back the clock and potentially undo everything...?
