The sixth of the nine orders of angels, also said to be called Authorities. It is said that they were the first order to be created. The Powers are the bearers of conscience and the keepers of history. They are academically driven and are concerned with ideology, philosophy, theology, religion and documents pertaining to those studies. Powers are the brain trusts; a group of experts who serve as advisers and policy planners. They are also the warrior angels created to be completely loyal to God. Some believe that no Power has ever fallen from grace, but another theory states that Satan was the Chief of the Powers before he Fell (see also Ephesians 6:12). Their duty is to oversee the distribution of power among humankind, hence their name.
"Origin: Israel. They are the third of the middle angels. Their name means 'power of God' and they are called the angels of victory. They patrol Heaven's corridors to ward off invasions by demons. They are the frontline soldiers of God's army, which puts them most at risk of being tainted. It is thus said that many of the fallen angels were once Powers."
Like Dominions and other angels, Powers support Yosuga. They appear as enemies in the ruins of Mifunashiro. A Dominion and a Power together can be found conversing there, and will ask the Demi-fiend whether they are also disgusted by the Manikin's desires for a world in which all are equal (answering in the affirmative will give considerable Yosuga points). Later, a Power which has been defeated by Noah is found in the Tower of Kagutsuchi. In battle, the Red Rider will summon Powers (up to two) whenever possible.
"The sixth class of angels, members of the Second Sphere. Their name signifies the power of God. They are also known as "Dynamis" and "Polantias". Powers are tasked by their masters with destroying sinners who defy Heaven. They serve largely as holy soldiers, seen as capable of both good and evil. This is because they have the most contact with devils, compared to any other type of angel and thus are the most prone to fall from grace. They patrol the corridors of Heaven, always ready to stand on the front lines and defend Heaven from demons and other enemies. Powers have a spiritual awareness four levels higher than humans. They help protect law and order in the natural world. They also took part in the Creation and serve as spiritual guides to all humanity. Camuel, leader of the Powers, commands one million of these angels, while Raphael, one of the four Archangels, oversees the class."

Power's shield can be acquired through a drop from the Powers that spawn with Raphael's field boss or in the Catacombs in Shinagawa. This item is called Gospel and grants a player the power to use specific expel affinity attacks when equipped.
"The sixth of the nine orders of angels. They are said to be the first line of defense in the hallways of Heaven to prevent demons from entering."
