Haniel, also known as Anael, Hanael or Aniel, is an angel in Jewish lore and angelology, and is often included in lists as being one of the seven archangels. Haniel is generally associated with the planet Venus and is also the archangel of the Sephirah Netzach. Haniel was sent to protect Maria during her pregnancy. He is the Angel of December and is associated with the zodiac sign Capricorn.
"The angel of beauty. His name means "the grace of God." He is commonly associated with Venus, and thus with Ishtar as well. His duty is to fasten the bonds of love between young men and women."

Aniel appears in Sector Eridanus as an optional boss in the EX Mission, Before the holy battle II. As a condition for defeat, he asks to be defeated within seven turns. If defeated, he can be fought along with Kazfiel in the EX Mission Before the holy battle III; he demands the average level of the Protagonist and his demons be of 45 or less.
Should both of these missions be completed and Aniel spoken to again with Law alignment, he will open the door to the titular holy battle - the imprisoned Mother Harlot. After her defeat, death or escape, Aniel will praise the Protagonist no matter which path was taken and reward him with the Amanomi Sword, the game's most powerful blade, equippable only with Law alignment.
Aniel appears as a boss in the Chaos and Neutral routes. He resides in Purgatorium - 5th Crown where he has set a barrier alongside other angels to prevent further entry. He repeats the same words as the other angels. Acting as a Steward to the new leaders, he gives a Challenge Quest on New Game Plus during the Law route called Four Wings, Four Heads. Residing on the path to Shene Duque, he requests that Flynn slay four demons in Tokyo so that they may become sacrifices to summon a certain angel.
Once the heads have been gathered he will perform the ritual to summon Seraph. Aniel mentions that they are the highest ranking of Angels and the greatest weapons as the flame of God. He plans on taking Seraph with him, but informs Flynn that gathering the appropriate angels will allow for him to summon Seraph. He thanks Flynn for his efforts before leaving. He is the client in the quest Taste of the Forbidden Fruit and Great Raven of the Underground, where he asks to meet on the path to Shene Duque, calling for Sister Gabby upon Flynn's arrival. After Mastema's defeat in the quest Great Raven of the Underground, he will appear before Flynn and give him his reward on the orders of Gabby.
Haniel appears in Devil Survivor as two separate entities. One is Aniel, a demon which can be fused by the player. The other is Anael, which appears as a palette swap of Sariel and is a boss that is usually paired with him.
Anael, along with Sariel, appears in Yuzu Tanikawa's ending, to oppose the protagonist's attempt to escape the lockdown, and in Naoya's ending, to attempt to dissuade the protagonist from staying with Naoya and becoming the King of Bel. Anael also possesses Purging Light, a Mystic attack capable of depleting the MP reserves of all of the player's teams. Like Sariel he joins Metatron in the final battle on Naoya's 8th Day if the protagonist chose not to kill humans.
"He is the angel of beauty, also known as Hanael. His name means "grace of God". He is generally associated with the planet Venus and performs a similar role as the goddess Ishtar. He gives rise to feelings of love amongst people and has the role of tying together young men and women. He is also thought to be the symbol of lasting friendship and lust. When he appears, it is said to be in the form of a beautiful man or woman."

"He is one of the Secundeis angels recorded by Johannes Trithemius, and is the spirit of Venus. He is considered to be the same as Haniel, who appears in the Book of Enoch. He is the leader of the Virtues and Principalities. His role is to watch over the rules of the world and protect those who make charms to ward off evil."
