correct me if i'm wrong, but isn't this one of the books you're seeking? https://www.pixiv.net/en/artworks/120467488
seems the author reprinted it on pixiv themself in july 2024 which is very based

the lapis & peridot one is currently available on suruga-ya (https://www.suruga-ya.jp/product/detail/ZHOTI434372?tenpo_cd=400338); since it's a marketplace listing (flea market/peer-to-peer) you can't buy it from suruga-ya's international storefront, but any standard jp proxy could get it for you. or uh i guess i could do it since i import my own doujinshi monthly anyway

and the leftmost one is here: https://www.suruga-ya.jp/product/detail/ZHOMI501063
couldn't find it on the international site (maybe because it's r18) but in fairness i did not look that hard -w-

if you run into any problems acquiring them you can contact me on discord @cirrus_dye; i can also clean/redraw but it seems you have that covered
