Knights of the Round Table

The Knights of the Round Table(ラウンドテーブルの騎士; Raundotēburu no kishi) is the name given to a group of human Knights(騎士; Kishi) whose work is to fight and kill supernatural creatures deemed as too dangerous to live in any realm, specially devils, composed mainly of descendants of the original Knights of Sir Arthur's Round Table from english mythos. They're introduced in Volume 11 of Highschool DxD: Яe-birth.

The leader of the Weiß team, Arthuria Pendragon, used to be part of such before her defection.

History
"A great group, bunch of good-natured fellows wanting to protect the world. It was a pity for me to defect, but eh?"

- Arthuria Pendragon The Knights of the Round Table are an english organization working under the English Kingdom, in charge to exterminate any form of evil that might bring harm to the human race after the events of the Great Apocalypse. Composed of descendants of the Original Knights of the Round Table, all of them able to wield the strongest of the Holy Swords, they symbolize the Human Struggle against the supernatural, and as such, even with their numbers reduced, able to strike fear and respect from other factions, including the Underworld and Heavens.

While mostly hereditary, seen that Sir Uther Pendragon, descedant of Arthur, was the one who started over the organization, it's leadership apparently can be changed to suit the best of their generations, as Uther saw that Arthuria, being descendant of Mordred and from the secondary branch of the Family, was worthier than his son Morrigan, passing down the position to her before her defection, in which when Morrigan again took leadership of such.

The group apparently doesn't hold lasting grudge against other factions if not provoked since their presence in General supernatural meetings and Peace conferences are constant without much trouble.

Members
Starting from Morrigan's father, Uther, The current Head of the Knights of the Round Table is currently Morrigan since Arthuria's defection, and formed mostly of Human descendants of the Original Knights and their signature swords.

Former Members
Members who, for some reason or another, were defected from the Knights.
