Divine Dragons Alliance

«Divine Dragon Alliance» (聖竜連合 (ディヴァイン・ドラゴンズ・アライアンス)) is «Sword Art Online»'s most active clearing guild. They are considered as one of the top clearing guilds in SAO. They have a one-sided rivalry with the «Knights of the Blood», since the DDA wish to hold the title of strongest guild in the game. Unlike the KoB, they are secretive about information and have their own farming grounds. The DDA has more than twice as many members as the KoB.

They were known as one of the top clearing guilds in the game, and often did anything to expand their power. Klein once stated that they would do almost everything to obtain rare items, even becoming orange to be the ones to attack a Flag Mob. For example, they attempted to follow Klein to obtain the Divine Stone of Returning Soul rare drop from the Christmas event boss Nicholas The Renegade, but were held off by the Fuurinkazan. They also insist on having the Last Attack on the boss during Floor clearing boss fights.

Trivia

 * It is possible that Lind is the actual leader of the guild, as he is a member of the DDA late on in the game, while he was one of the two leaders of the clearers early on in the game and was likely going to start a guild with his party members after they reached the 3rd Floor.
 * In the Web Novel version of the story, the Divine Dragon Alliance is said to have disbanded at some point, due to bad leadership. This however was omitted from the Light Novel, and you can see the Divine Dragon Alliance in the Anime, right before the raid on the 75th Boss, The Skull Reaper.
