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...

Thanks to Asterius joining the battle and Fels' revival magic, Wiene's death was averted and the Xenos narrowly escaped alive. However, Bell obstructed efforts by the subjugation force against the monsters who had emerged on the surface - a fact which will not be erased. Bell faces cruel words and harsh stares throughout all of Orario.

Even worse, he receives information that the Xenos who came to the surface were unable to return to the dungeon and remain in hiding...
