Seima Miyazawa (宮沢清磨) could be a misspelled version of Kiyomaro Miyazawa (宮沢聖麿) since 宮沢清磨 is only credited on BC & SxF (2 shows where 宮沢聖麿 is also credited) but no confirmation so far
Definitely should indeed be Kiyomaro Miyazawa here, not "Seima Miyazawa." Kiyomaro confirmed participation here https://twitter.com/kiyo_8092/status/1728424574386360798 then shortly after tweeted about their named being misspelled in the credits https://twitter.com/kiyo_8092/status/1728430617044594768
