The “Imagenae Holy Grail War” collaboration event launches in the game on July 24 and will feature a story supervised by the writer of the original Fate/stay night visual novel, Kinoko Nasu. In the collaboration’s second part, two new playable characters from Fate/stay night will join the game: Rin Tohsaka and Gilgamesh. You can check out both characters in their new outfits and their descriptions below.
“The contract is complete. Relax, I’m not really one for strict hierarchies… well, not for most people, anyway. Got that, my Servant?”
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…
“Huh? Where am I? Why isn’t there any magical energy here at all…? The Ho-Holy Grail? I’m saved! Sorry, just gonna borrow this!”
“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.”
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.
Takashi Takeuchi, the character designer of Fate/stay night, is the original concept artist for both characters’ appearances in Honkai: Star Rail. Rin is an Erudition: Quantum type while Gilgamesh is a Destruction: Lightning character. Both characters will be available in the collaboration Warp starting from 12:00 (server time) on July 24. Gilgamesh will also be available to claim for free starting July 24 until the end of Version 4.6. Players will get to choose between Gilgamesh and Archer once the collaboration starts on July 24.
Honkai: Star Rail is available now for PlayStation 5, PC, Android, and iOS.
