1x6 - Ms. Koizumi Loves Ramen Noodles

Koizumi gets up early in the morning to eat some dried sardine ramen, catching the eye of Yū's older brother, Shū, who tries the same thing. On a hot sunny day, the girls take Koizumi's cue and try various types of cold hiyashi ramen. While attending a ramen fayre at a museum, Koizumi comes across a lost German girl named Hannah, sharing some of her ramen with her before helping her reunite with her mother. As thanks, she receives a voucher for some German-style ramen.
