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.
Koizumi is a mysterious and attractive high school student. But what most people don't know about her is that she's a ramen master who is always on the lookout for great ramen restaurants. Everyday, she goes hunting for real-life places serving the best ramen dishes and delightfully eats the delicious noodles. The way Koizumi downs a giant bowl of ramen–more adeptly than any large man–will amaze and delight you!
