Michael

Michael is the leader of the Angels and Seraph. He is the only Archangel and the original God's very first creation who took His place as leader after He died in the war. His current goals are to recreate the lost members of the Heavens (mainly the Seraphim).

Appearance
Like Azazel, he has twelve wings growing from his back, and unlike other Angels whose wings are white, his wings are colored gold, further symbolizing his position as leader.

History
The first creation and right-hand man of the Biblical God, he serves as the leader of the Angels and assisted the Biblical God in the Great War against the Devils and Fallen Angels. After God died in the Great War, the Angels were forced to retreat as Michael and the other Seraphs try to activate the Heavens' system and were successful in activating it with Michael as the center as he takes over the place of his creator as the maintainer of the Heavens' system.

Birth of the Breast Dragon Emperor
He appears in Volume 4 of the light novels to give Issei the Holy Sword Ascalon, the Dragon Slayer sword that was wielded by St. George. He later agrees to the signing of the treaty between the three factions, as all three can no longer afford another Great War.

Sometime after the creation of the Brave Saints system, Michael angelized both Irina Shidou and Dulio Gesualdo as his Ace and Joker. In Volume 6, Michael sent Irina to Kuoh Academy as the Angels' representative.

The Heroic Oppai Dragon
In Volume 12, Michael initially intended to enter the Realm of the Dead with Azazel and Sirzechs Lucifer to confront Hades, the God of the Realm of the Dead, for breaking the treaty but was stopped by Azazel. Michael, however, still sent his Joker, Dulio, to accompany them.

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

Michael's true power, however, comes from the fact that he is now the one in control over the system created by God in the distant past, which is what causes harm to Devils who come into contact with blessed objects, provides miracles, and determines who can be saved. Unfortunately with Michael in charge, the system is inferior to how it was with God running it.
