Honkai: Star Rail Concert 2025 Delivers Major Surprises, Including Fate/stay night Collab and New Honkai Teaser

HoYoverse celebrates interstellar soundscapes and reveals what's next for the Honkai universe

What began as a celebration of music ended with one of the most exciting announcements of the year for Honkai fans. HoYoverse wrapped up its spectacular Honkai: Star Rail Concert 2025 in Shanghai with a live global broadcast, stunning fans with a trailer tease for a new Honkai game and fresh details on the long-awaited collaboration with Fate/stay night [Unlimited Blade Works].

Held from May 1 to May 3, the concert offered a sweeping musical tribute to the game’s journey since its launch on April 26, 2023, blending live orchestral performances with themed visuals from across the multiverse of Honkai: Star Rail. Those who couldn’t make it to Shanghai were able to participate through special screening events featuring merchandise giveaways and themed activities.

Fate/stay night Collaboration: Details Finally Revealed

One of the biggest highlights of the event was the official reveal of gameplay details for the upcoming Honkai: Star Rail x Fate/stay night [Unlimited Blade Works] crossover, first teased at Gamescom 2024 and the Version 2.4 Special Program.

The limited-time event, titled “Sweet Dreams and the Holy Grail,” is set to launch on July 11, 2025. It will introduce Archer and Saber as playable 5-star characters:

• Archer (The Hunt: Quantum) — Available for free upon logging in when the event begins. Known for his cynical resolve and sense of justice, Archer is expected to add high-value burst damage and narrative depth to the cast.

• Saber (Destruction: Wind) — Obtainable via Event Warp. A lone Heroic Spirit with a storied past, Saber will fight in the Astral Express’s version of a “Holy Grail War.”

Both characters were designed by renowned artist Takashi Takeuchi, with the storyline supervised by Fate creator Kinoko Nasu, ensuring that the crossover retains the authenticity and tone of the original visual novel and anime series.

Surprise Teaser: A New Honkai Game on the Horizon

In a surprise move that few saw coming, HoYoverse also dropped an easter egg teaser trailer for a brand-new Honkai title. Though brief, the video set the internet ablaze by featuring familiar characters like Kiana and Blade in what appeared to be a creature-battling game format, signaling a bold new direction for the franchise.

While no official title has been confirmed, multiple trademark filings suggest the name “Honkai: Nexus Anima.” If confirmed, it could mark a major shift in gameplay and possibly unite multiple timelines or characters from across GGZ, HI3, and HSR.

Fans who caught the teaser during the concert were quick to speculate on Reddit and social media. From Pokémon-style mechanics to cross-universe storytelling, the theories have only fueled further anticipation.

Honkai: Star Rail is available on PC, iOS, Android, Epic Games Store, and PS5 and has surpassed 150 million downloads across all platforms.
