After Mariemaia's forces have taken control of Brussels, Dekim (along with Relena and Mariemaia) retreat to a completely protected bunker that is practically buried underground. The bunker proves to be no help when Heero blasts it open. In this sudden moment of seemingly defeat, Dekim calls Mariemaia to join him at his side and rise up once again. Relena, in a desperate act to stop her, slaps her. Dekim, who's pissed off by now, goes to shoot Relena but ends up shooting Mariemaia who jumps in front of Relena. After shooting his own granddaughter and laughing about how he can always get another pawn, he is shot by one of his own troops and, thus, ends the war of the Endless Waltz
