Azrael (Azraaiyl) is the name of the Archangel of Death in some extrabiblical traditions. He is also referred to as the angel of death in Islamic theology, known as Malak al-maut, earning that title and that duty by assisting God in the creation of Adam, by gathering the clay from the Earth itself.
Although some sources have speculated about a connection between Azrael and the human priest Erza, he is generally depicted as an archangel whose history long predates this figure. Rather than merely representing death personified, Azrael is usually described in Islamic sources as subordinate to the will of God "with the most profound reverence;" when he extracts the soul from a dying person, a good dying person will not feel the pain from the removal of the soul from his body, Azrael removing it with ease, and for those who are bad, the removal of the soul is tough and difficult. In Jewish mysticism, he is identified as the embodiment of evil, not necessarily or specifically evil itself. Depending on the outlook and precepts of various religions in which he is a figure, Azrael may be portrayed as residing in the Third Heaven. Riffian (Berber) men of Morocco had the custom of shaving the head but leaving a single lock of hair on either the crown, left or right side of the head, so that the angel Azrael is able "...to pull them up to heaven of the Last Day."
"The Islamic angel of death, said to have four faces and four wings. Azrael has a book in which he inscribes and erases the names of those who are born and die. His body is covered in eyes; when one blinks, someone in the world dies."

Azrael appears as a summonable demon and as an NPC in Sector Horologium B6F. Depending upon the alignment of the protagonist when spoken to, he will either praise him (Law Path) or promise revenge (Neutral and Chaos Paths).
Azrael appears in the New Game Plus Challenge Quest, Death on Wings. He is closing in on Ikebukuro in the alternate world Blasted Tokyo. Azrael is found on the world map and does not speak during the battle. Azrael is faced on the Chaos and Neutral routes in Purgatorium - 4th Crown, where he repeats the same words as all the other angels in the battle.
After being captured during their scouting mission to the Eastern Kingdom of Mikado, Azrael blocks Nanashi and company's path when they try to recover their equipment from the monastery during their escape. If Nanashi has the Red Jinbaori armor and recovered Hope's Ring from Naraku, he can negate most of Azrael's attacks during the battle. After his defeat, Azrael is unlocked for fusion in the Cathedral of Shadows.
Azrael can teach Nanashi the Agidyne, Makarakarn and Tetrakarn skills through his Demon Whisper but cannot pass on Blink of Death in any way. He benefits from learning Darkness, Fire, Light and support skills.
