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...
This must be a sign that 
there's also a thirteenth maiden!
!هذه إشارة عن وجود عذراء ثالثة عشر
Das kann nur bedeuten,
dass es eine 13. Priesterin gibt!
¡Debe ser la señal de que hay
una decimotercera doncella!
¡Debe ser la señal de que hay
una decimotercera doncella!
Questo vuol dire che esiste anche
una tredicesima Sacerdotessa!
Isso deve ser o sinal de que
há uma 13ª sacerdotisa!
Должно быть, где-то есть 
и тринадцатая дева созвездия!
