Yufa's elder brother, a knight, and currently a subordinate of the Dark Lord. Keough is childhood friends with Iruga and accompanied him to investigate Glast Heim. The ruins proved to be too much for the group and forced them to flee; however, their escape route was blocked by an Abysmal Knight. Despite Iruga's protests, Keough distracted the knight as Iruga got Roan and Yufa out; however, before Iruga could make it back, Keough was stabbed and the doors of Glast Heim closed. In the beginning, it is assumed he died, but the group later learns that he was brainwashed and corrupted by the Dark Lord.
