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.

No, tal vez la indecencia

Так... А может, именно пошлость 
делает её особенной девой созвездия?
