«Divine Dragons Alliance» (聖竜連合(ディヴァイン・ドラゴンズ・アライアンス), Sei Ryū Rengō or Divain Doragonzu Araiansu?, abbreviated as DDA) 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 death 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.
