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...
But that would still be a second round. 
Not the thirteenth maiden.
.لكنّ ذلك يظلّ جولة ثانية وليس العذراء الثّالثة عشر
Jedoch würdest du sie damit
nur ein zweites Mal durchpoppen.
Pero seguiría siendo un segundo round.
No el decimotercero.
Pero seguiría siendo un segundo round.
No el decimotercero.
Mais ça ne change rien !
Ma quello sarebbe comunque solo un secondo giro,
non la tredicesima Sacerdotessa!
Mas continua a ser uma segunda rodada,
não é o mesmo que a 13ª sacerdotisa!
Это будут повторные ритуалы с прежними 
девами, а вовсе не с тринадцатой!
