Satsuriku no Tenshi EP13 - I'm Not Your God.

Zack continues watching a recording of an interview between Danny and Ray, where Ray reveals that her parents were abusive and hated her and each other. One night, her father finally snapped and stabbed her mother to death, prompting her to take her mother's gun and shoot her father to death. Afterwards, she stitched their bodies together in order to create the "perfect family" and lived happily with them until the police arrived. Noticing her blank, blue eyes, Danny reveals to Ray that his mother committed suicide due to him having been born missing an eye, and he becomes obsessed with Ray since her eyes resemble his mother's. Angry and disgusted, Zack storms back to where Ray and Danny are and proclaims his suspicions that Ray is in fact the "angel" of B1, which Danny confirms, and reveals that Ray was sent to B7 after finding newfound faith in God by reading a Bible. Knowing that she lied to him, Zack angrily declares that he is not Ray's God and asks her if she will kill him, as a trespasser on her floor. Ray flees, luring Zack through more traps until he manages to corner her in the last room. He once again asks her if she intends to kill him when Danny arrives and holds him a gunpoint. Cornered by the two of them, Ray then calmly draws her gun and fires.
