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.
If no one notices it for three days...
...إلّم يلحظها أيّ أحد لثلاثة أيام
Wenn meine Strähne für drei
Tage niemand bemerkt …
Si nadie lo nota por tres días…
Si nadie lo nota en tres días…
Si personne ne le remarque
pendant trois jours…
Se nei prossimi tre giorni nessuno lo noterà...
Se ninguém perceber aquilo
por três dias...
Если в течение трёх дней 
его никто не заметит...
