Summer! Swimsuits! The beach! Illya and the others enjoy the beach to fullest, playing along the shore and celebrating their birthday in a beach hut♪ But the popsicle seller they encounter there turns out to be the fierce foe they fought a hard pressed battle against... And to make matters worse, Ruby adds a Love Potion that makes Shirou go crazy! Will Illya's desires come to fruition in an unexpected way?!
Ah, she's brought something even 
more troublesome into the mix...
Aha, Hauptsache, das Ganze

Ah, ha traído otra cosa ideal
 para empeorar la situación...
Oh, ed ecco che magicamente
aumentano ancora i problemi...
Ah, ela quer colocar algo ainda 
mais problemático no meio disso...
