Fujimoto Kouhei, a salaryman who is always late for work, goes around searching for the greatest ramen. His dream is to open a great-tasting ramen shop.

Shiomi Yutori just graduated college but has only recently tasted ramen six months ago after coming back to Japan from the US and falling in love with it. She is incredibly talented in cooking, and has impeccable taste buds and food sense. She applies to the Serigawa Project, a company started by the famous ramen chef Serizawa Tatsuya that operates as a restaurant consulting company that focuses on ramen shops. Yutori is just as creative as she is blunt, even criticizing Serizawa’s ramen with its flaws. Although Yutori gets the job at the company, she will need more than creativity and cooking skills if she wants to master this job.

Mutou Ginji runs an izakaya, but his half-baked approach to cooking leaves it on the verge of closing. One day, he falls into a well at a temple, and finds himself in the Edo era, where he meets a brother and sister who are responsible for the shogun's meals. Two eras of cuisine collide as Ginji showcases modern Japanese dishes while learning about delicious dishes from the Edo era. [Written by Denji]
