DEUS (ＤＥＵＳ（デウス） Deusu?) is the special investigative team organized in order to defend the Earth against alien aggressors. Although they live as normal people, members of DEUS can be called into action at any given time. Agents call each other by code name rather than their actual names. Led by the Commander of DEUS (ＤＥＵＳ（デウス）司令 Deusu Shirei?), he informs agents of their missions through the VC. It is revealed to be an A.I. that controls all of the world's information on behalf of the shadow rulers. The agent's main equipment are the Ultra Gun (ウルトラガン Urutora Gan?) which is a small laser gun, and the VC (Video-Ceiver) (ＶＣ（ビデオシーバー） Buishī (Bideo Shībā)?) wristband which is for all-purpose communication.
