If it seems like the sets are out of order, they're not: the artist sometimes will go back and redo some of the sets with lactation and/or pregnant variations. If there are any duplicates, please let me know.
001 - 024 is, according to the artist, a remake of a previous Artoria set from their Pixiv account (https://www.pixiv.net/en/artworks/67786903). 513 - 560 is, according to the artist, a remake of a previous Osakabehime set from their Pixiv account (https://www.pixiv.net/en/artworks/70792957). 579 - 590 are, technically, supposed to be a timed backer-exclusive set, but since I already uploaded them before the artist announced they were timed-exclusives, I'll leave them here in this gallery.
