Pretty sure we've been pulling stuff from this pixiv account for a couple of years now. Granted we haven't pulled anything really recent from it so good finding it again!
ah yes, it's been a long time since i've seen anything new from this artist. the last time i trolled pixiv for os images was probably a year and a half ago, so thanks for the heads up.
Yeah, I've wondered who did the work too.
