Koizumi walks into a ramen shop alone and becomes a different person. The cool, untouchable girl at school dissolves the moment she tastes broth, her face softens, her whole body relaxes, she starts talking to herself about umami and pork fat like nobody's watching. The show is just her discovering new shops and eating, but it's really about finding the one thing that makes you completely yourself, the thing you don't perform for anyone else. Every episode is ten minutes of watching someone be honest with food instead of people. That's the entire appeal, and it never stops working.

Koizumi is a quiet transfer student who rarely talks and seems cool and aloof to the people around her. Hidden behind that elegant exterior is a true ramen expert who goes looking for a great bowl every single day, willing to wait for hours in the sun or travel far from home to get one. Her outings stop being solo once classmate Yuu Oosawa becomes infatuated with her and starts tagging along without asking. Yuu keeps being amazed by how much Koizumi can eat, and along the way she discovers just how many kinds of ramen exist. A gourmet comedy with a slice of life feel, it draws its humor from the gap between how Koizumi looks and what she loves.
