Hlasy PJ Mattson

A Genius Society #83 member and the elusive master of Herta Space Station in HoYoverse’s turn-based RPG, Honkai: Star Rail. Her voice comes across youthful and doll-like, with a bright, crisp cadence that turns cuttingly smug in an instant—playful on the surface, yet coolly detached and condescending underneath. In English, she’s voiced by PJ Mattson.

The true mastermind behind Herta Space Station in HoYoverse’s *Honkai: Star Rail*, an interest-driven member of the Genius Society who operates through puppets modeled after her younger self. Her voice is crisp and cool with a slightly lofty, unimpressed tone—delivering lines in a clean, deliberate cadence that feels sharp, analytical, and effortlessly self-assured. Even when she’s playful, there’s a dry, detached edge that keeps her sounding in control.
