Reiji Kageyama

After family tragedies, his Gate of Foresight was warped into the Jet-Black Gate of Darkness, which lets him transport objects, change his outfit, and perform various attacks. He has clairvoyance, which the Commander theorizes helped him open his gate by letting him "Grasp a future beyond his reach." His real name is revealed as Yuji Mitsuoka. In Gate Keepers 21 he returns as a middle-aged businessman working for A.E.G.I.S. Network, missing several body parts because of overusing his Gate.
