Yoruko Kabuya's development began sometime during Danganronpa Another's development, specifically during the creation of Chapter 6.5. Originally, her name was "Yoruno Shibuki", and her talent was "Super High School Level Cabaret Girl". However, this talent was considered too obscure at the time, and so it was later changed. Additionally, her personality was described as being more "mundane and devilish" compared to her personality in the final game.

Her design did not go through many changes during development: the initial design had her hair down instead of up, and featured two additional bows on her outfit. For the prototype design, the design of her necklace was changed, the bows were removed, she gained (and later lost) an earring, her name and personality were changed, and her hair was tied up.
