Spicy Curry Udon Noodles / Fujiyoshida City, Yamanashi Prefecture

While on their way to their next business destination, the food truck breaks down. While it is being repaired, the three leave the car, with Akira sourcing ingredients, Natsuki promoting the restaurant, and Yuki doing his laundry at a laundromat. While Yuki is waiting for his laundry to finish, he meets the strangely dressed musician Mimura Tokio (Tama Shinya). Mimura left his band due to differences in direction, and ended up in town by chance. Seeing Tokio thinking about going somewhere far away, Yuki remembers his father, who was also a musician, and to cheer Mimura up, offers him a job working in a snack bar. On the way home, they ask the snack bar owner for directions on where they can operate a food truck. However, there is a condition that they must use "certain ingredients".
