Mahō Sensō Odcinek 12: Gone From This World

Having finished his special training at Camelot, Takeshi returns home to find Gekkou emerging from their house with Twilight gripped in his right hand - dripping with blood. The nightmarish vision Takeshi had once seen through Twilight's power has finally come to pass. Gekkou claims that he struck down their mother in self-defense. Unable to suppress his rage at seeing his loved ones hurt any longer, Takeshi finally finds the heart to battle Gekkou decisively.
