Masaaki Endo did most of the effects in this iconic scene, Aoyama is probably involved with some of the character cuts. Tagging Mihara as well as the crowd master, he likely did something here

a lot of edits to keep the scene at a reasonable length as well
0:00 - 0:55: Masaaki Endo
0:56 - 1:13: Hiroyuki Aoyama (the smoke is confirmed at minimum)
1:14 - 1:20: artist_unknown (It may be Aoyama but Endo doesn't know)
