The long-awaited second phase of the Honkai: Star Rail × Fate/stay night: Unlimited Blade Works collaboration is officially dropping in Version 4.4, launching on July 24, 2026. Following the massive success of the first part with Saber and Archer, HoYoverse is bringing two iconic characters: Tohsaka Rin and Gilgamesh (the King of Heroes) as playable 5-star units.

Players can log in during the event (running through Version 4.6) to claim one free 5-star collab character: either Gilgamesh or Archer. Rin will be limited banner-only.
