Honkai: Star Rail's version 4.3 special program confirmed a second Fate/stay night: Unlimited Blade Works collaboration, announcing 5-star Rin Tohsaka and 5-star Gilgamesh alongside redeemable livestream codes and a June 1 update. Artists and cosplayers are producing illustrations, short animatics, chibi comics, edits, and cosplays focused on the crossover designs. Creative work concentrates on Rin's UBW outfit, Gilgamesh's in-game model and free release, and new HSR content such as Himeko's teased form. Kinoko Nasu is credited to supervise the collab story and Takashi Takeuchi as original concept artist.
