When Zack gets injured during the fight against Cathy, Ray encounters a reverend, Abraham Gray, at B2 who reveals himself to be the one who designed the game in order to figure out the definition of "religious faith" in people's hearts, appointing the various floor masters as "angels" that are not afraid to kill without hesitation.

When the duo arrives at B1 though, they come to a house filled with fake flowers and the stitched corpses of a couple, driving Ray hysterical and desperate for Zack to kill her immediately.

While counseling her at the hospital, Danny took an interest in her blank blue eyes and used his authority as an "angel" to bring her to B1, making her the final floor master.

However, after discovering a bible, Ray suddenly found herself unable to cope with the realization and guilt of what she had done, believing that no one would accept her after what she did, so she developed suicidal ideations and erased her memory, causing Danny to send her to B7 with the hopes that she would return to her "original self".
