Artoria, or Altria in the games' official English translation, is the first collab character. As a playable unit in Honkai Star Rail, Saber will be aWindDestructioncharacter.

The only way to acquire Saber will be to pull her on her limited-time banner. She also has Eidolons like therest of the HSR roster.

Archer - Emiya Shirou

The second collab character is Emiya Shirou. He will be aQuantum Huntunit and is also a limited-time character like Saber. However, leaks suggest that you will be able to acquire him for free. If you want to progress his Eidolons, though, you’ll have to obtain them through his banner.

Honkai Star Rail x Fate/stay night collab date

The leaks put the collab going live soon:HSR version 3.4. If the updates follow their usual cadence, this patch will fall on June 16, 2025. This only barely falls into the third quarter of the year, which was the officially confirmed timeframe for the collab.

Again, this is unconfirmed information, but we can get some corroboration soon. As early as May 6, the drip marketing for new characters on version 3.4 could be posted. If these end up being Saber and Archer, then that means the leaks were correct. If they don’t, then we’re in for a surprise.
