エイブラハム·グレイ
from Angels of Death
Abraham Gray is one of the characters in Angels of Death. He serves as the floor guardian of Floor B2, using drug-induced illusions to study sacrifices. He is considered as the most significant antagonist in the story. Gray is an extremely eloquent and serious man, able to mesmerize his listeners through words, and harbors a cold and logical heart without mercy. Despite his position as a reverend, Gray himself doesn't believe in the existence of God, simply taking the role because he is intrigued by religious faith in people. He seems to have a thirst for knowledge, going to any length to acquire the knowledge he seeks even if it means sacrificing people's lives. He appears to speak in a Shakespearean-like language, always replacing normal words with "thou", "thy", "whilst", and so on.

In her search, she comes across a man covered in bandages. He introduces himself as Zack and he wields a grim-reaper like sickle. A strange bond is struck between them, strengthened by strange, crazy promises… These two, trapped in this strange building, don't know why fate has placed them there. But they will work together desperately to find a way out… (Source: MU, Edited)
