With a new job cleaning up cells at an asylum, Keirah thinks her time with Noir is at an end. That all changes when she's called up to the fourth floor - a floor she's forbidden from due to the prisoners housed there - and finds him, caged and unassuming. He isn't supposed to be here. She isn't supposed to love him. But fate has brought them together again, and there isn't any arguing with fate.
Both Reese and Andie are on the hunt to track down Keirah from Noir's clutches once more, but this time around, Keirah finds she doesn't want to be found. With a war brewing and Black Wing in danger by law enforcement and one persistent District Attorney, the duo are too distracted to ask themselves an important question:
Was Keirah taken, or did she leave of her own free will?
And if it's the latter, is she even worth saving?
