"A lot of people on the team are fans of Black culture," Nakayama said. "In order to make her as authentic as possible, we spoke with many Black employees within the company. We also hired consultants to help us design the character and her mannerisms."
Nakayama mentioned that one of the things that defines Street Fighter to him is a diverse set of characters from all over the world and ensuring that they are real and authentic is an important part of development. Both Nakayama and Matsumoto repeatedly emphasized that "open communication" is a priority for them in Street Fighter 6 —a lesson they learned while working on Street Fighter V — and believe that designing characters authentically is part of that ethos.
There are very few (documented) cases of this happening, so its great to know and it certainly shows.
