Gabriel

Gabriel is an Angel and a Seraph, a group of Angels that are the guardians of the Throne of Heaven.

Appearance
Gabriel is an extremely beautiful woman with curly blonde hair and a voluptuous figure and is known as the most beautiful woman in Heaven. Because of her beauty, she is also popular in the Underworld.

Personality
Gabriel has a humble and polite personality. She has also been shown to be a clueless person, not even realizing that Issei is a pervert or when he was about to use his Dress Break on her.

History
One of the Four Great Seraphim created by the God from the Bible, Gabriel serves as the guardian of the Throne of Heaven along with the other Seraphim. Like the other Angels, Gabriel assisted in the Great War against the Devils and Fallen Angels and was forced to retreat after God died. She and the other Seraphs then tried to activate the Heavens' system and were successful with Michael as its center.

The Heroic Oppai Dragon
She appears in the side story "Armageddon at Sports Day!", where she is seen reminding Michael of the opening ceremony for the Sports Day among the Three Great Powers and introduces herself to the Gremory Team. She later participated in two sports events: the Cavalry Battle, where she nearly became one of the victims of Dress Break, and the Baton Relay, which she won after Issei and Azazel started a battle with each other, allowing Gabriel to head to the finish line without any trouble and contributing to the Angel's victory.

Powers & Abilities
As an Angel of the highest order, a Seraph, Gabriel can create weapons of light with ease, and most likely wields power equivalent to an Ultimate-Class Devil.
