Honkai Star Rail – Herta

“Member 83 of the Genius Society. The real master of the space station. An incredibly intelligent yet unsympathetic scientist.”

Herta is the master of the eponymous Herta Space Station, and takes on the appearance of dolls that were modeled after her younger self. She is also the one in charge of developing the Simulated Universe, the “rogue-like” game mode in Honkai Star Rail. In-game, she is a 4-star Ice character belonging to The Erudition path. Erudition units are proficient at dealing damage to multiple enemies, and Herta is great at taking down waves in battle.


“This is Herta. I'm busy right now. This is my ranged puppet's automated-response mode: Hello everyone. Hope you have a wonderful day. Goodbye.”

Herta is voiced by PJ Mattson in the English voiceover, meaning she shares voices with Baiken of Guilty Gear: Strive, Sylvanas Windrunner from “World of Warcraft, and… Cheer Bear from Care Bears. Meanwhile, her Japanese voice actress is Yamazaki Haruka, who has also voiced Kati Räikkönen from Akiba’s Trip: Undead & Undressed and Grani from Arknights.

Official Herta Introduction

“Herta Space Station's true master.

As the human with the highest IQ in The Blue, she only does what she's interested in, dropping whatever project immediately the moment she loses interest — the best example being the space station.

She typically appears in the form of a ranged puppet. “It's about seventy percent similar to how I looked as a child.” — Herta”
