It's most likely between Mizuhata, Sugiura, Naoto Abe and Masashi Takai as they're the people credited in the book that we know can do sakuga stuff.
I thought the wind fx looked like Sugiura but peeps who know his stuff better than me have tagged him on this eps other post. With that in mind I'd say it's probably Mizuhata as nothing in the book matches his handwriting for this ep
