Agetaro is the heir to his family’s long-running tonkatsu (fried pork cutlet) restaurant in Shibuya, Tokyo. He spends his days chopping cabbages and slacking off because he has nothing else better to do. One day, he goes to a dance club to deliver a bento, and is thrilled to get a chance to speak to Sonoko, the girl he secretly has a crush on. He also experiences the excitement of the dance floor grooving to the music for the first time, and is filled with an uplifting sensation that he has never felt before. To win Sonoko’s heart, Agetaro decides to become the “Tonkatsu DJ,” a guy who can cook both tonkatsu and the dance floor!
