Abraham Gray  

The Reverend, エイブラハム・グレイ

The B2 floor master is an experimenter who created this facility with the goal of defining religious faith. He gathers all the other floor masters and gives them victims to observe. This person has a talent for speaking eloquently, but also possesses a cold and logical mind without any compassion towards their subjects. To further manipulate his victims, Grey uses drugs that cause hallucinations, allowing him to see into their true selves.
