The 13th maiden was not male... A girl claiming to be the 13th maiden shows up before Itsuki. She sets out to confess her love while wearing an outlandish '80s outfit.  However, Itsuki fails to notice, and continues his search.
But you were protecting me
 this whole time.
.لكنّي كنتُ محميًّا من قبلك طوال هذا الوقت
Aber du hast mich die ganze
Zeit über so sehr beschützt.
Pero tú me protegiste todo el tiempo.
Pero tú me has protegido todo el tiempo.
mais j’ignorais
que tu veillais à ce point sur moi.
Invece...
Mas esse tempo todo
eu fui protegido por você.
Но всё это время... 
ты защищала меня.
