First image and last four images aside, ordering is oldest-to-new Pixiv images followed by oldest-to-new Nijie images, and so on
Update: Added four new images to the Pixiv section, in addition to removing two redundant images and reordering.
Update 2: Added 36 images retrieved from artist's Twitter and archived Tumblr. Some of those images were put in the Pixiv section since they were deleted from the artist's Pixiv. The ones that weren't on Pixiv are in their own sections.

Thanks for reminding me, I was able to find his archived tumblr which in turn linked to his Twitter. Also, I can't upload these to the gallery itself but here are the remaining eight images that were deleted from his Pixiv that I can't find. I was able to get the thumbnails thanks to saucenao:

If anyone has any of these you can drop a link in the comments and I'll add it.
