Jun'ya Ota, better known by the pseudonym ZUN, is the sole creator of the Touhou Project, serving as the series' game developer, composer, and illustrator. While not a fictional character within the Touhou universe, ZUN is sometimes depicted in fan works and official materials as a character representing himself, often seen with a beer and wearing a hat. ZUN's role is pivotal, as he is entirely responsible for the development, music, and design of the beloved bullet hell games.
