A major publishing company Genbu Shobo has moved ahead with a publish plan of a new Japanese dictionary named "Daitokai". A young sales staff in Genbu Shobo, Mitsuya Majime is poor at expressing himself, and he loves books. A veteran lexicographer Araki finds out that he has a natural facility for the Japanese language, and headhunts him to the Lexicographical Department. So Majime becomes a highly competent lexicographer over time.
