Junpei Yoshino (吉野 順平) A high school student who can see curses.
Black hair, pale skin, is seen wearing a white t-shirt with a black square during his debut. Later, he is seen wearing a black jacket that is presumably his mother's.
He is a bit of a recluse and was bullied by some of his classmates. But he takes to Itadori fairly quickly after he realizes that they share a common favorite movie. He says that even if there existed a button that would kill all those he hates, he probably won't press it. But if there was a button that would kill every person who hated him, he'd press it without hesitating.
