Honkai Star Rail 4.5 banners: Complete list of characters
Phase 1 banners
Robin Summeretto headlines the first half of the Honkai Star Rail 4.5 banners. She takes on her role as head of the Oak Family while quietly investigating Gopher Wood’s “legacy,” all without stepping away from the stage.
In battle, she sings alongside her bird band to buff the team, building up Vibes as allies take action. Once her Vibes reach their threshold after her Skill is used, the team enters a Fever Pitch, gaining stacking attack buffs that scale with how often allies act.
Her Ultimate lets her select a teammate to act immediately and regenerate Energy, while raising her own Vibes further.
| RARITY | HONKAI STAR RAIL 4.5 BANNERS PHASE 1 CHARACTER | PATH | COMBAT TYPE |
| 5-star | Robin Summeretto | Remembrance | Wind |
| 5-star | Hyacine | Remembrance | Wind |
| 4-star | Dan Heng | The Hunt | Wind |
| 4-star | Qingque | Erudition | Quantum |
| 4-star | Gallagher | Abundance | Fire |
The Phase 1 Light Cone banner pairs Robin’s signature, “Rise and Sing.”
Phase 1 of Honkai Star Rail 4.5 banners runs from Wednesday, August 26, 2026 through Saturday, September 12, 2026.
Phase 2 banners
The second half of the Honkai Star Rail 4.5 banners shifts focus to Aventurine, who trades his usual gambling den for a beach.
Aventurine Waveflair works his connections behind the scenes even during a vacation, using the downtime to test his theories about a traitor among the Ten Stonehearts.
His combat style draws on his surfer persona, attacking with a beach volleyball or by riding the waves. Using abilities, or having teammates act, builds Punchline and Fervor; once Fervor caps out, he triggers a bonus Elation Skill that hits every enemy and adds several instances of random single-target damage.
During his following Aha Instant, that Elation Skill grows stronger, scaling with the number of actions the team has taken.
| RARITY | HONKAI STAR RAIL 4.5 BANNERS PHASE 2 CHARACTER | PATH | COMBAT TYPE |
| 5-star | Aventurine Waveflair | Elation | Quantum |
| 5-star | Ashveil | The Hunt | Lightning |
| 4-star | Sampo | Nihility | Wind |

Honkai Star Rail 4.5’s story
With Lord Ravager Asat Pramad’s threat resolved by the Express Crew, a new danger emerges: the Voracity. Their arrival plunges Planarcadia back into crisis, pushing the Trailblazer to look beyond the planet for aid.
To find the strength needed for Planarcadia to survive, the Trailblazer sets out to evade the Voracity’s interference and reach Astropolis, the IPC’s headquarters, where navigating the company’s upper management becomes the path to securing real help.
Astropolis is framed as the crown jewel of the IPC’s business empire — both a luxury address for corporate elites and a vacation spot for tycoons and officials across the Pan-Cosmic Trade System.
This Trailblaze Continuance chapter finds the Trailblazer on an unexpected interstellar getaway alongside Robin and Aventurine, even as both companions work cases of their own in the background.
Honkai Star Rail 4.5 events
Alongside the Honkai Star Rail 4.5 banners, the update adds a set of new events.
Overdrive: Whirlwind Grand Prix is a racing event in which the Trailblazer takes on the role of team principal, building a crew to compete for the title of brightest new stars on the track.
Minuscule Great Adventure runs alongside the Grand Prix as a lighter, stage-based challenge event.
The Divergent Universe also receives an update, with the “Planar Fissure” and “Realm of the Strange” modes both getting double-drop events.
A new piece of Trailblaze Fashion arrives in the form of an electronic emoti standee headwear item called “Aw, Look Up Here.”
From version 4.5 onward, players can speed up story dialogue by toggling the feature on or off at any point during story missions.
The permanent mode Currency Wars: Zero-Sum Game receives an expansion, alongside system-wide optimizations.
Honkai Star Rail x Moondrop and Zenless Zone Zero collaborations
Separate from the Honkai Star Rail 4.5 banners, HoYoverse pairs Honkai Star Rail with audio brand Moondrop for a Sparxie-themed collaboration, bringing online and offline events across multiple regions.
A crossover with Zenless Zone Zero is also slated for a future version, bringing characters from that game into the Trailblazer’s cosmic journey.
