Throughout the entire O-Parts Hunter universe, there are angels and demons (some of which are sealed within humans) with amazing powers, all of which are being searched for by the Stea Republic (angels) and the Zenom Organization (demons) in order to awaken what is assumed to be a weapon within a Kabbalah and a reverse Kabbalah that are found on the North and South Pole respectively.
As of the beginning of the time-skip all but four Angels have yet to be inserted into the Kabbalah, those four being Metatron, Zadkiel, Samuel, and Sandalphon.
