Asipu (討ち祓う者 Ashipu) is the designation given to those who are able to reduce the influence of Dingir.
As with the Puluhtu, they are treated as a subset of and included in the Dingir tribe in the Z/X - Zillions of enemy X- TCG, complete with the Dingir character for "ASIPU" on the right side of the card and a regular tribe as their secondary tribe. They also possessed a slightly different Dingir icon on the left side of the card frame.
