The summer heat is on!
Koizumi-san looks at the trio loudly suffering from the heat with disdain while she continues on her ramen pilgrimage. 
Yuu wills herself to follow her, and Koizumi-san declares that she will be having "hiyashi" ramen.
What exactly is this "hiyashi" ramen?
I just got a whiff of dried 
sardines off of a beautiful girl.
لقد شممت رائحة سردين مجفّف 
.من فتاة جميلة قبل قليل
Percibí olor a sardina seca
de una hermosa chica.
Noté olor a sardina seca
de una hermosa chica.
Acabei de sentir o cheiro de peixe
seco vindo de uma garota bonita.
Мимо меня прошла красотка,
от которой пахло сардинами.
