Honkai: Star Rail Announces Version 4.3 Details
Honkai: Star Rail's Version 4.3: The Lethe Below the Living is set to release on June 1, 2026, and will continue the Astral Express' venture into the chaos of Planarcadia. Mortenax Blade will make his official debut as a 5-star fire nihility character, along side the rerun of Yao Guang in phase one and the reruns of Cyrene and Phainon in phase 2. There will also be a new continuation in the Fate/Stay Night collaboration, after the previous releases of Saber and Archer last summer, there will be a new addition to the collaboration lineup with Gilgamesh and Rin Tohsaka.
After the climatic events of the previous version we reach our potential end to the story of the well-loved Stellaron Hunter, Blade. The Trailblazer and Blade are set to begin their exploration into the World in Canvas separately. Blade takes his step into the canvas on his own accord to seek the power of the Voracity to melt away the flesh of Shuhu within his body in hope to bring an end to his curse but the direction of this decision still remains blank in Elio's script. The Trailblazer will take another route towards the Inkford Hermitage in order to obtain the answers about the Graphia family, Phantasmoon Games and even the mysteries surrounding the express' navigator Himeko.

New Character: Mortenax Blade
The new version introduces Mortenax Blade, a familiar face to the trailblazers, who will be following the Path of Nihility as a 5-star fire character. During battle, this character uses his ultimate to help set up a special Bounded Field and overall enter an enhanced state to increase his output damage against enemies. Using this enhanced state, it will unlock his skill that will be able to deal even more DMG while building up for the next ultimate release. When an ally attacks an enemy on the field, they will inflict a debuff that will accumulate a special charge that once full this skill will automatically be used to regenerate extra energy.
