Comedian Noritake Kinashi as his character Norimaro, hanging out with the Marvel Super Heroes vs. Street Fighter devs & playing himself in the game vs a kid who’s also playing as him.
From a comment on the video–time stamps of Capcom staff appearances:
3:26 Yoshiki Okamoto - Executive Producer
3:58 Akira Yasuda (aka Akiman) - Original Art Work
20:32 Hiroaki Kondo - Sound Director
23:16 Tetsuya Iwanaga - Voice Actor of Ken
24:15 Yuko Sasamoto - Voice Actor of Sakura
25:04 Osamu Hosoi - Voice Actor of Dan
27:41 Yoshiharu Yamada - Voice Actor of Dhalsim
43:39 Yoshiki Okamoto - Executive Producer
According to Norimaro | Marvel vs. Capcom Wiki | Fandom , Okamoto HATED having Norimaro in the game, but Akiman thought he was a hoot.
Google Translate on my phone says the suit at 3:38 is “Ryuichi Hirata, Capcom Co., Ltd. Tokyo Branch Manager.” Google results show him listed in various trade publications and legal filings as President of Capcom USA from '94 to '96; so I wonder if he could have been a real behind-the-scenes power player at the company after moving back to Japan by '97, when MSHvSF and probably this video came out, and was perhaps one of the people who forced the Norimaro deal through, over the protestations of producer Okamoto and–also according to the fandom wiki–of Marvel.
