>>32713304Definitely has to have been ready for a while, You've got to assume actually making the model after the design is finalized would take a while. She only drew the "new" Servant for the first time a month or so ago. Interestingly enough, during the KINGWORLD MV, Kuro still had her original design and the Servants that appear in there also resembled her old design more with white ear fluff and generally looked a bit different with red eyes and some fiery elements such as tail and mane. My best guess is that the new Kuro design has to have been finalized somewhere between the point in time work on KINGWORLD was done and roughly a month ago, and FBK updated the Servant design to closer match the Kuro redesign when making that stamp.
