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?
Don't tell me she's your love child!
!لا تقولي لي أنّها ابنتك غير الشّرعيّة؟
Ein uneheliches Kind etwa?!
¡¿Es que es tu hija?!
¡¿Es que es tu hija?!
– C’est sa fille cachée ?
– Quand même pas…
Magari è la sua figlia segreta?!
Não me diga que é sua filha!
Неужели дочь?!
