Infiltrating it, Rin and the others witness that the Illuminati, led by Lucifer, are pursuing a grand plan to fuse demons and humans. Meanwhile, Yukio, obsessed with his father's death and his own origins, gradually loses his mental balance and begins dangerously drifting toward the enemy in his hunger for power. The brothers' paths quietly but decisively begin to diverge, and the story accelerates toward an unavoidable all-out clash between True Cross and the Illuminati.
