Robin Summeretto is the swimsuit variant of Robin, arriving as a 5-star Wind character on the Path of Remembrance. She headlines the first half of Honkai Star Rail’s version 4.5 update, and her limited-time banner goes live the moment the patch does across every region at the same time.
Quick answer: Robin Summeretto releases with Honkai Star Rail version 4.5 on August 26, 2026 at 11:00 AM (UTC+8), which is 03:00 UTC. Because the update rolls out simultaneously worldwide, players on America servers can start pulling on the evening of August 25 local time.
Release time: August 26, 2026, 11:00 AM (UTC+8) / 03:00 UTC
Robin Summeretto release time by region
The patch launches at the same instant everywhere, so your local unlock time depends only on your time zone. Version 4.5 also runs a week shorter than a standard patch, but that does not change the release time itself.

| Pacific Daylight Time (PDT) | August 25 | 8:00 PM |
| Mountain Daylight Time (MDT) | August 25 | 9:00 PM |

The update goes through the usual server maintenance before it opens. Once the game is back online at the times above, Robin Summeretto’s banner becomes available directly through the Warp menu.
Robin Summeretto banner window and duration
Robin Summeretto appears on the Summer Chorus event banner during phase one of version 4.5. Unlike some 5-star reruns and debuts, her banner does not carry over into the second half of the patch. It closes when phase two begins, so you have the first half of the version to pull her.
| Server region | Start | End |
|---|---|---|
| America (UTC-5) | Aug. 25, 2026, 10:00 PM | Sep. 12, 2026, 11:59 AM |
| Europe (UTC+1) | Aug. 26, 2026, 4:00 AM | Sep. 12, 2026, 11:59 AM |
| Asia (UTC+8) | Aug. 26, 2026, 11:00 AM | Sep. 12, 2026, 11:59 AM |
Characters and light cones in phase one
Robin Summeretto shares the first half of 4.5 with a rerun of Hyacine, another 5-star Wind character on the Path of Remembrance. Her signature light cone, Rise and Sing, runs on a separate light cone banner at the same time as her character warp.
| Type | Name | Rarity / details |
|---|---|---|
| Character | Robin Summeretto | 5-star, Remembrance, Wind |
| Character | Hyacine | 5-star, Remembrance, Wind |
| Character | Dan Heng | 4-star, The Hunt, Wind |
| Character | Qingque | 4-star, Erudition, Quantum |
| Character | Gallagher | 4-star, Abundance, Fire |
| Light cone | Rise and Sing | 5-star, Remembrance (Robin Summeretto’s signature) |
| Light cone | Long May Rainbows Adorn the Sky | 5-star, Remembrance (Hyacine’s signature) |
The standard gacha rules apply on her event warp. The 5-star rate is 0.6% with a guarantee at 90 total pulls, and the 4-star rate is 2.55% with a guarantee every 10 pulls. If your first 5-star on the banner is not Robin Summeretto, the next 5-star is guaranteed to be her.
How to confirm the banner is live
You will know Robin Summeretto has released when the maintenance ends and the game lets you log back in at the times listed above. Open the Warp screen and the Summer Chorus event banner will show her as the featured 5-star, with Dan Heng, Qingque, and Gallagher as the rate-up 4-stars.
If you still see the previous version’s banners after maintenance should have finished, the update likely has not fully applied yet. Restart the client so it downloads the latest version data, then check the Warp menu again. Players at Trailblaze Level 4 or above before maintenance typically receive Stellar Jades as compensation once the patch is live, which you can put toward her banner right away.
