■テイルズ オブ ヴェスペリア ～The First Strike～（劇場/2009）　原画
図書館での戦闘シーン

However, there is no source on the wiki, so anyone could have written it.

I investigated a lot of Kawashima's credits around this time though and they do seem to be inspired by Miyazawa (post #146445) so it's not impossible that their work is here. I think it's more a matter of how much of it is actually theirs.

Miyazawa was also credited for genga and he's not presumed elsewhere while the supervision was also really high - it's a phenomenally well-made film.

All this to say that I would take the tag with a grain of salt. It's entirely possible it's correct but it could also be misleading
