I had no idea I had tagged it something other than hayashi custom, because his art style is unmistakable, and usually when the auto-parser can't extrapolate the artist from the URL, it doesn't tag an artist (leading me to research the artist and tag it correctly). This time, it must have extrapolated the wrong artist, and I clicked it blindly because that's what I do when it gives me an artist. That'll teach me to trust it when Pixiv is screwing around with its URLs.
UPDATE: Confirmed - that's what happened. Tried to DanbooruUp it again and it gave me "shimizu" as the artist instead of hayashi custom.
