Honkai: Star Rail version 4.3 launches June 1 with Blade-focused story update
Blade is at the center of Honkai: Star Rail 4.3, and June 1 is the handoff point from one Planarcadia chapter to the next.
Honkai: Star Rail’s next big story beat lands with a clean cutoff: Version 4.3, The Lethe Below the Living, launches on June 1, 2026, right as Version 4.2 ends at 2026/06/01 06:00 UTC+8. If you are saving Stellar Jade or lining up your next mobile login, that is the date that matters, because this patch is framed as a major step forward for Planarcadia rather than a side quest between bigger chapters.
The immediate hook is Blade. HoYoverse says the Trailblazer and Mortenax Blade will separately venture into the World in Canvas, with Blade’s thread built around his attempt to use the Voracity’s power to remove the Shuhu inside his body. The payoff is not subtle: the release teases that the result could be death or rebirth, and that the Trailblazer will witness it. That makes 4.3 feel like a character climax, not filler.
The official trailer, posted on May 22, 2026, backed that up with a high-visibility cast list and a warning that the video contains development content. Daman Mills voices Blade, Shaun Mendum voices the Male Trailblazer, and the preview also features Silver Wolf, Ruan Mei, Pearl, Ryusuke, and Asat Pramad. That kind of rollout usually means HoYoverse wants players watching closely, not skimming past a routine version notice.
There is also a playable angle to watch. The release identifies Mortenax Blade as a 5-star Fire-Type character on the Path of Nihility, with an Ultimate called Fornax Ex Corpore that deploys a special Bounded Field and pushes him into an enhanced state. For anyone planning around pulls, that is the detail to lock onto before June 1, because the patch is putting Blade front and center both in story and in combat identity.
Version 4.3 also widens the lore instead of just recycling old beats. The update introduces Graphia, the “Mother of Imagenesis,” a thousand-year-old ancestor of the Murata family who once used a single brush in Amber Era 2148 to encanvas Ahatopia and repel Demons From Beyond, even as the Weathering Curse burdened her family. The Trailblazer is headed to Inkford Hermitage to warn Graphia about Asat Pramad, which ties the patch’s cosmic stakes to a specific place and a new major figure.
That is why June 1 matters. Version 4.3 is not just the next patch on the calendar; it is the handoff into a Blade-led Planarcadia chapter, with a story payoff, a new 5-star face, and a direct transition from the current version into whatever comes next.
