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.

Not a Shred of Regret
With My Dried Sardines
لا توجد ذرّة ندم مع سمك 
السّردين المجفّف خاصّتي
Mit meinen Trockensardinen
gibt es nichts zu bereuen.
Ni un solo lamento
con mis sardinas secas
Ni un solo lamento
por mis sardinas secas
Non abbiamo alcun rimpianto
per le nostre sardine essiccate
Não há ressentimentos
 com meu peixe seco
Ни капли сожаления не останется
 после моих сушёных сардин
