HoYoverse has released the Honkai: Star Rail Version 4.5 update, ‘To Roll the Stars in Astropolis’, on August 26, 2026. The update transitions the narrative to the Interastral Peace Corporation (IPC) headquarters in Astropolis, where players seek aid for Planarcadia following the defeat of Lord Ravager Asat Pramad. The story introduces characters such as Aventurine and the Ten Stonehearts member, Sugilite. The patch introduces the limited five-star character Robin • Summeretto (Wind, Path of Remembrance), accompanied by a character PV titled ‘Chasing the Wind’. Robin • Summeretto provides team buffs and energy regeneration, making her particularly effective in Remembrance-focused or Follow-Up Attack team compositions.
