Honkai: Star Rail Launches Fate UBW Collaboration Phase 2 With Rin, Gilgamesh
The direct involvement of Nasu and Takeuchi in a gacha game collaboration, down to skill design, marks an unusually deep integration of the Fate IP into Honkai: Star Rail's systems rather than a simple cosmetic crossover.

HoYoverse began the second phase of the Honkai: Star Rail and Fate/stay night [Unlimited Blade Works] collaboration on July 24. The update adds the collaboration-exclusive 5-star characters Rin Tohsaka (voiced by Kana Ueda) and Gilgamesh (voiced by Tomokazu Seki), each available in their own event warps with increased drop rates. Players can also choose one free 5-star character from Gilgamesh or Archer (voiced by Junichi Suwabe) until the end of Version 4.6. The collaboration event story, titled "Phantom Creation: Holy Grail War," casts players as mages from another world who enter a Phantom Holy Grail War alongside Rin Tohsaka. The collaboration PV, titled "A Long-Awaited Reunion," includes visual references to Fate/Grand Order, Fate/Zero, and Fate/strange Fake. The project was produced with the cooperation of Fate series creator Kinoko Nasu and illustrator Takashi Takeuchi, who oversaw story composition and character skill design.
- Rin Tohsaka's in-game path is Erudition with Quantum damage; her event warp is "Shining Red Jewel," which also increases drop rates for the limited 5-star Light Cone "Small Fire That Twinkles Quietly (Erudition)."
- Gilgamesh's in-game path is Destruction with Lightning damage; his event warp is "Primordial Star of Creation," which also increases drop rates for the limited 5-star Light Cone "I as I Am (Destruction)."
- The free character choice lets players pick either Gilgamesh (Destruction: Lightning) or Archer (Hunt: Quantum, voiced by Junichi Suwabe) until the end of Version 4.6.
- The collaboration PV "A Long-Awaited Reunion" shows Saber, Archer, and Lancer from the first wave alongside the new characters.
- The PV includes a shot of Ishtar (from Fate/Grand Order, with Rin Tohsaka as her vessel) using her Noble Phantasm "An Gal Ta Kigal Shē."
- A scene where Gilgamesh is stabbed with the "Jewel Sword Zelretch" is noted by sources as a possible homage to Kirei Kotomine stabbing Rin's father Tokiomi Tohsaka with the Azoth Sword in Fate/Zero.
- The PV ends with the logo "Fate/star rail Fake" in the same font as Fate/strange Fake, and a poster behind Lancer holding the Holy Grail mirrors the key visual for Fate/stay night [UBW] second season.
- All collaboration event warps are held for an extended period, running from July 24, 2026, at 12:00 server time (13:00 Japan time).
- HoYoverse is running a PV release commemorative campaign on the official X account where followers can repost for a chance to win character goods.
