Honkai: Star Rail’s Version 4.5 — titled “To Roll the Stars in Astropolis” — gets its official Special Program livestream this Thursday evening. Two familiar faces return in summer swimwear forms, a brand-new character is set to be unveiled for the first time, and HoYoverse will lay out the full roadmap for the patch before it goes live on 25 August. Here is everything confirmed ahead of the broadcast.
When and Where to Watch the Version 4.5 Special Program
The broadcast kicks off on Thursday, 14 August 2026 at 7:30 PM SGT (19:30 UTC+8). You can catch it live on the official Honkai: Star Rail channels on both YouTube and Twitch. The stream typically runs between 45 minutes and an hour, covering new banners, events, and any gameplay changes coming to the patch.
As with all Honkai: Star Rail Special Programs, HoYoverse distributes redeem codes live during the broadcast — keep a browser tab open on the official site so you can enter them as they drop.
Robin Summeretto — The Diva Trades Her Gown for a Floral Swimsuit
Officially unveiled via HoYoverse’s drip marketing campaign, Robin Summeretto is a 5-star Wind character on the Path of Remembrance. The Remembrance path typically centres on summoning a memosprite companion to deal damage on the Trailblazer’s behalf, so this summer variant plays very differently from the original concert-ready Robin you may already have built.
Robin Summeretto is expected to headline the first half of Version 4.5, with her banner anticipated to open on 25–26 August alongside the patch itself. Exact dates and Warp rates will be confirmed during Thursday’s broadcast.
Aventurine Waveflair — Same Smile, Completely Different Playstyle
Aventurine Waveflair is a 5-star Quantum character on the Path of Elation. Where the original Aventurine built around shields and survival, the Elation path shifts his role toward damage output — specifically follow-up attacks. If you loved the character but wanted a more offensive take, Waveflair is worth watching closely. HoYoverse teased him with the quip: “Friends, we meet again! I just wrapped up a sponsored shoot… Now that I’ve been promoted to P46, I can finally go on vacation. Want to relax and enjoy your time with me?”
Aventurine Waveflair is slated for the second half of Version 4.5, with his banner window expected to open around 16 September. The Special Program will confirm the precise schedule.
Pearl: A New IPC Character Joins the Story
The Special Program will also feature a first look at Pearl, a new character affiliated with the Interastral Peace Corporation. No further details — element, path, or rarity — have been confirmed ahead of the stream. Pearl’s debut marks another expansion of the IPC faction’s roster in the game’s story, so Thursday’s broadcast should shed light on her role in the 4.5 Trailblaze Mission.
When Does Honkai: Star Rail Version 4.5 Launch?
Version 4.5 is scheduled to go live on 25 August 2026 for North American servers and 26 August 2026 for Asia and European servers. The patch follows the standard six-week Honkai: Star Rail update cadence. Maintenance downtime details will be announced closer to launch.
The Special Program on 14 August will also reveal what new events, rewards, and gameplay mechanics are coming with the Astropolis summer update. Tune in this Thursday at 7:30 PM SGT on the official YouTube or Twitch channels, and check our Game News section for a full summary after the broadcast.
