As Yū tries to invite Koizumi to a WcDaniel's restaurant, Koizumi explains how she once had saimin noodle soup from a WcDaniel's branch in Hawaii. Later, Yū goes with Koizumi to a peculiar restaurant where customers eat in secluded cubicles and order using forms. After finding Koizumi collapsed from starvation due to her favorite restaurant being closed, Yū takes her back to her house and makes her various homemade ramen dishes, which prove to be a hit with her.
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!
