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?!
Well, I happen to know that Illya has

Ich weiß dafür, dass Illya ein Muttermal
an einer Stelle hat, die ihr peinlich ist!
¡Yo soy la que sabe que Illya tiene 
un lunar en un sitio vergonzoso!
¡Yo soy la que sabe que Illya tiene

uma pinta num lugar constrangedor!
