The tag mizuno has a both a wiki written for the sporting goods/sportswear brand as well as a pixiv picture URL. There's no other information. I'm confused--is this an artist or a copyright?
it appears that mizuno refers to the brand and the posts are very consistent to this. the pixiv url is currently used for the the artist hidaka_medaka. it's probably a mistyping?
Probably. So that URL's for hidaka_medaka? Case solved--someone just needs to turn the mizuno tag into a copyright and transfer that URL to the aforementioned artist.
