@sunshineandlolipops: You seriously didn't notice that that one is just another art thief/repost account, NOT the original creator? Lazy!
The actual source is an old kusuguri.jp site (where this was the intro animation) that's since gone, from a Japanese artist. I haven't been able to find if they've created a Pixiv since.
I can contribute the gallery that I have saved if you want, should be merged rather than posted separately like this.
EDIT: This gallery /g/524590/d219cad3bb/ also seems to be mostly releases from the same artist/group.
EDIT2: Found the artist: https://www.pixiv.net/users/2573093

Thank you @whade!
I had noticed that was an art repost account but I couldn't find the original pictures anywhere
