Robin is coming back, and she looks nothing like the stage diva from Penacony. The version 4.5 drip marketing has officially introduced Robin Summeretto, a reimagined take on one of Honkai Star Rail’s most popular support units. This time she trades her gown for a floral swimsuit and lands in Astropolis, the IPC’s seaside resort, hunting for inspiration for a new song.
Quick answer: Robin Summeretto is a 5-star Wind character on the Remembrance Path, confirmed for Honkai Star Rail 4.5. Her full kit has not been shown yet, and version 4.5 is expected around August 25, 2026.
Robin Summeretto rarity, element, and Path
The drip marketing locks in the three details that matter most before a banner goes live. Robin Summeretto is a limited 5-star, and she walks away from her original Physical Harmony identity entirely. Her new form runs the Wind element and the Remembrance Path, putting her in the same camp as other memosprite-summoning units.
| Detail | Robin Summeretto |
|---|---|
| Rarity | 5-star (limited) |
| Element | Wind |
| Path | Remembrance |
| Release version | Honkai Star Rail 4.5 |
| Original form | Physical, Harmony |
Because she sits on the Remembrance Path, the teaser image shows her memosprites, depicted as small birds carrying musical instruments such as guitars. That fits the Remembrance summoning mechanic, where a unit calls in a separate entity to fight alongside the team.
The Astropolis setting and her new look
The redesign leans fully into a vacation theme. The stage-ready gown is gone, replaced by a floral swimsuit suited to Astropolis, the IPC’s resort located in the Epsilon system of Planarcadia and the Trailblazer’s next stop. HoYoverse pairs every drip marketing reveal with a short in-character blurb, and Robin’s frames the trip as a creative retreat.
“Soaring clearest skies and bluest oceans, wings sweep up the sea spray, transforming it into a new melody. Following the lingering echoes of memory, she embraces the unexpected along the way, seeking inspiration for a melodic variation— Beyond the melody, how else can the Harmony sing?”
That nod to “lingering echoes of memory” lines up with the Remembrance switch, tying her new kit to the idea of chasing down memories rather than simply buffing allies. She slots into a wider 4.x trend of established characters returning in alternate forms, following reworks like Himeko Nova and Mortenax Blade.
When Robin Summeretto releases
She arrives with version 4.5, which is expected to begin around August 25, 2026, once update 4.4 wraps up. Given that she was the first character shown in the drip marketing order, her banner is likely to headline the first phase of the patch rather than the second half. HoYoverse has not posted a locked release time, so treat the date as a projection from the usual patch cadence.
Note: Her debut comes after Himeko Nova, another reimagined 5-star, so expect her to anchor the early stretch of 4.5’s warp banners.
What is still unconfirmed
The drip marketing only confirms her rarity, element, and Path. Her full kit, including her Skill, Ultimate, and how her memosprites behave in combat, has not been published. Those numbers typically surface during the version livestream and the in-game preview that follow later in the cycle.
If you are saving Stellar Jade for her, the safest approach is to wait for the official kit reveal before committing pulls. Until then, the only certainties are the ones HoYoverse has shown directly: a 5-star Wind Remembrance Robin, dressed for the beach, headed to Astropolis in version 4.5.
