His Pixiv and current Twitter have been entirely purged, and there's also two past Twitter accounts he's already deleted, according to Danbooru's artist page. Only 40-ish works have been uploaded and preserved on Danbooru and Gelbooru, and the two existing accounts alone have much more than that, so it's likely that a good deal has already been lost. So I figured I'd dump what currently exists here.

There's a good deal of overlap between the two accounts. In the Misskey images that were pngs, the differences comapred to the Bluesky jpgs were imperceptible, so I preferred the pngs. In the case of the Misskey webp images, they had noticeably worse artifacting than the Bluesky jpgs, so I preferred the jpgs. There was one case of the same image having distinct differences between sites beyond artifacts, a Miku with different shadows, so I just kept both.

The result was 83 images from Misskey, 40 from Bluesky, 15 from Danbooru that were not present on either existing account, and 3 that were Gelbooru but not Danbooru.
