The Dreams of Beasts (Dix Perdix) (S03E07)

Bell and Fels chase after the Xenos and end up entering the man-made labyrinth, Knossos, the base of the Ikelos Familia. There, they watch as Dix's curse causes to the Xenos to unwittingly fight each other... and the madness of a man held prisoner by his cursed blood begins to reach toward Wiene... Meanwhile, on the Eighteenth Floor, the strongest Xenos begins to move, and not even high-level adventurers like Ryu and Aisha, or first-class adventurer Shakti, can stand in the way... (Crunchyroll)
