Angel

The Angels (天使 Tenshi) are one of the three major factions in High School DxD, alongside the Devils and Fallen Angels.

Summary
Originating from Heaven, the Angels are powerful beings who serve God, and have the powers to inflict pain upon demons due to their light-based powers. After the death of God in the Great War of the three factions, the Angels were incapable of increasing themselves until the creation of the Brave Saint system.

In Volume 12, it is revealed that there are also traitors in the Heavens who are giving out information to the Chaos Brigade. Ironically, these top-class Angels were able to do so without being fallen due to a loophole in Heaven's system. These Angels, however, become fallen after leaving the Heavens and escaping to the Chaos Brigade.

Appearance
All Angels have white wings and a halo above their head. The Archangels have golden wings and halos on their Head. Also, their power is determined by the number of wings they have (Dulio, for example, has five sets of wings).

Abilities
All Angels have light-based abilities that can cause severe damage to Devils, and can create numerous light-based weapons such as spears, arrows, and swords, with the spear being the most commonly used weapon. After God's death in the Great War, the Brave Saint system was created by the current God, the Archangel Michael, to increase their lost numbers by reincarnating humans into Angels.

Seraph
Seraphs are Angels who are guardians of the Throne of Heavens. They are the ones maintaining the system used by the God in the Bible following His death. The members of the Seraphs are the Archangel Michael, Gabriel, Raphael and Uriel. The only Seraphs to appear in the series, however, is Michael and Gabriel.

Archangels
The only known Archangel is Michael, the leader of the Angels and Seraph.
