During Version 4.3 special program, HoYoverse revealed that Honkai: Star Rail x Fate / Stay Night [Unlimited Blade Works] collab is rolling out in summer 2026 with brand-new content update. Players can look forward to two new collab characters: Tohsaka Rin and Gilgamesh.
Prepare for “Imagenae Holy Grail War” to officially launch on July 24.
Rin Tohsaka (5-star Quantum Erudition)
Hailing from a world beyond our universe where magic and magecraft coexist, this young mage tirelessly hones her skills. She is the Sixth Head of the Tohsaka family, a prestigious lineage of Fuyuki City mages.
Currently studying under a renowned master at the “Clock Tower” who has deep ties to the Holy Grail War, hopping across dimensions and planes just to finish an internship assignment… But Planarcadia has something unexpected in store for her.
“The contract is complete. Relax, I’m not really one for strict hierarchies… well, not for most people, anyway. Got that, my Servant?”
Gilgamesh (5-star Lightning Destruction)
The King of Heroes from the dawn of human history, hailing from a world beyond the stars. Possessing a nature two-thirds divine and one-third mortal, he claims a natural-born prerogative to rule over all of creation.
Laughing out loud today as always, right up until getting dragged into another world by some adversarial Goddess—
This time, he will once again reclaim everything that is rightfully his as king.
“Stellaron, my treasure. When you reach the end of your journey, I shall seal you within the deepest depths of my treasury, in the safest place of all… Hmph. That said, your ‘Trailblaze’ shall endure for a long time yet, reaching even beyond the ultimate horizon of my own foresight.”
