Josuke and Okuyasu spot a group of hornet-shaped Stands, known as Harvest, picking up loose change and chase them back to its user, a middle school student named Shigekiyo Yangu. Learning how much money Shigekiyo made just from loose change, Josuke and Okuyasu strike up a business friendship with him, using Harvest to search for discarded stickers and vouchers that can be exchanged for larger cash rewards. During their search, the boys manage to find a winning lottery ticket with a 5-million yen jackpot, a prize Shigekiyo is reluctant to share with Josuke and Okuyasu.
