Itsuki finds out that in addition to Stardust Labyrinths where the "Impurity Lords" dwell, there is also the 13th labyrinth, as well as the existence of the 13th maiden. He sets out to find the maiden. However, there is the possibility that the 13th is a male. Although not quite convinced, he seeks all the male candidates he could think of...
How did they just allow an 
Impurity to roam around free?
كيف سمحوا لنجاسة بأن تحوم في الجوار طليقة؟
Wieso lebt hier eine
Befleckung ganz normal?
¿Cómo permitieron
que una impureza deambulara?
¿Cómo dejaron libre a una impureza?
Comment ça ?
Elles vivent là-bas, non ?
Perché hanno permesso che
un'Impurità andasse in giro liberamente?
Como uma Impureza
existe aqui sem problemas?
И Нечистому позволили 
тут разгуливать?
