It's tagged as "original" on Pixiv, but the artist mentions "quite likely that the bridge was ABENO." Oddly enough, there's a "One Piece" (ワンピース)tag in there. Referring to the dress, I suppose.
The "bridge" part is part of the name: Abenobashi. Hence "She turned out to look like Arumi from Abenobashi". It is indeed tagged as original though...
Doh! Thanks--the google translation wasn't awkward enough to prompt me to second-guess it. I should have learned by now that google translate hates names.
