Amaterasu was one of the great beings forged from the power of a human soul, a Usugurai. It like the other Usugurai, served Ze before the time he employed Angels. However, in Ze's great battle to save Ardor, the Usugurai fell, Awaken seizing the beings Amaterasu and Tsukoyomi.
They from then on were continuously seen attacking Ardor, leading Awaken's Dreamspawn. However, they were always accompanied by a third, previously unknown Usugurai, the enigmatic Tiamat.
It is said that in the presence of a combined effort, Ardor would be powerless to stop the Three Chaos Dragons.
