Shigechi, a high school student, was first seen after Josuke followed some of his Harvest's stands during a coin collecting spree in fear of finding a potential enemy stand user. At first Josuke and Okuyasu believed him to be a complete idiot by his strange demonstration of generosity to share the wealth he had just accumulated by Harvest (which he did in order to become their friends), though Josuke insisted on not taking advantage of his naivety, but instead work together with Shigechi and then equally share the spoils. Soon Josuke and Okuyasu's plan backfired as Shigechi turned on them, insulted at being called an idiot and selfishly not understanding that they deserved the equal share of the money they had all worked for together. This started a wild goose chase after him at which point Shigechi revealed that Harvest's advantage relies heavily on his numerous stand parts. Using multiple attacks from Harvest's men combined with dirty tactics, such as having Harvest inject alcohol directly into the blood stream of Josuke and Okuyasu, Shigechi proved to be a tough opponent.
After being subdued, Shigechi finally admitted that Josuke and Okuyasu were indeed deserving of one third each of the money they had gotten together. They then became friends at school.
Later, due to an unfortunate coincidence, Shigechi mistakes Yoshikage Kira's bag for his and takes it school, not knowing that Kira stored the hand of a dead woman inside. When confronted by Kira, he refuses to give it up, leading to the bag being ripped open and the hand inside to fall to the ground. With his homicidal nature revealed, Kira uses Killer Queen to plant an explode a bomb on Shigechi's face. Critcally injured, Shigechi attemps to reach Josuke, who can heal his injuries, at the high school. However, Kira planted a bomb on the doorknob leading to Josuke's classroom, and when Shigechi grabs it, it explodes, ultimately killing him. Before disappearing, a single Harvest manages to bring a button from Kira's suit to Josuke and Okyasu. He is seem by Remi and Arndold ascending into the sky while on fire, screaming in pain. His death is triggers Josuke to begin the hunt for Yoshikage Kira.
