Josuke and Okuyasu spot a group of hornet-shaped Stands, known as Harvest, picking up loose change from under soda machines, ATMs, and mailboxes, and chase them back to their user, a middle school student named Shigechi Yangu. Learning how much money Shigechi 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. However, things go sour when Shigechi greedily gives the duo only a small fraction of the money earned rather than splitting it 50/50. During their search, the boys find a winning lottery ticket with a 5 million yen jackpot, a prize that Shigechi is reluctant to share with Josuke and Okuyasu.
