Black Swan's Voice Actors and Her Penacony Legacy in Honkai Star Rail

I won't pretend to be calm about Black Swan. From the moment she drifted into Honkai Star Rail's Penacony narrative, she felt less like a character and more like a half-remembered dream with perfect posture. Honestly, the first time I heard her speak during the Version 2.0 buildup, my brain just folded in on itself. That voice—soft, deliberate, and faintly amused—carried the weight of someone who collects secrets the way other people collect souvenir spoons.

Her arrival in Penacony brought not only an eerie new region but also one of the most memorable vocal performances in the game. By 2026, Black Swan has settled into the roster as a graceful, enigmatic support, yet the conversation around her voice acting still hasn't cooled down. Let me tell you, it's rare for a role to feel this perfectly cast across four different languages.

🎙️ The Many Voices Behind the Memokeeper

Black Swan is one of those characters who changes shape depending on the language you choose. In every version, though, there is a shared quality: restraint. She doesn't shout, she insinuates. The voice cast had to walk a tightrope between elegance and hidden danger, and they did not miss.

Language	Voice Actor	Notable Previous Roles
English	Arryn Zech	Blake Belladonna in Justice League x RWBY, Gentiane in Girls' Frontline
Japanese	Nabatame Hitomi	Nanao Ise in Bleach: Thousand-Year Blood War, Ylva in Vinland Saga
Chinese	Yang Menglu	Localization performance for the Chinese audio track
Korean	Kim Ha-young	Localization performance for the Korean audio track

English: Arryn Zech

Arryn Zech brings a cool, almost conversational intimacy to Black Swan. If you have followed her work, you already know she can move from vulnerable to unreadable in a single breath. Her previous roles include Blake Belladonna in Justice League x RWBY: Super Heroes and Huntsmen, Gentiane in Girls' Frontline, and The Ripper in Wandering Witch: The Journey of Elaina.

In Black Swan's English lines, I hear that same layered control. She makes prophecy sound like pillow talk and threats sound like poetry. It's the kind of performance that rewards you for wearing headphones, because half the meaning hides in the margins.

Japanese: Nabatame Hitomi

Nabatame Hitomi has been doing this for a long time, and it shows. With a career stretching well beyond a decade, she has played Nanao Ise in Bleach: Thousand-Year Blood War, Ylva in Vinland Saga, and Touko Yotsuya in Mieruko-chan. Her game credits are just as stacked, including Nihilister in Goddess of Victory: Nikke, Camila in The Seven Deadly Sins: Grand Cross, and Symmetra in Overwatch.

For Black Swan, Hitomi leans into a mature, unhurried tone. There is no rush in her delivery, just the calm certainty of someone reading a future that has already been written. You know what I mean? It's quietly terrifying.

Chinese and Korean: Yang Menglu and Kim Ha-young

The Chinese and Korean versions complete the ensemble. Yang Menglu voices Black Swan in Chinese, while Kim Ha-young handles the Korean performance. Although their earlier resumes are not as widely documented in the materials I pulled together, their involvement speaks to how seriously Hoyoverse treats global localization. A character like Black Swan cannot survive on a single great performance alone. Each language team has to preserve her mystery while keeping her emotionally legible.

🔮 Who Is Black Swan?

Black Swan is a Memokeeper of the Garden of Recollection. She aligns herself with the faction that worships Aeon Fuli of the Remembrance Path. That detail matters because memory is not passive in Honkai Star Rail; it is a current that can be collected, reshaped, and weaponized. Black Swan moves through that current like a fish through dark water.

Her official playable debut arrived alongside the Version 2.0 update and the reveal of Penacony, the dream-soaked world that turned a lot of player expectations upside down. In the narrative, she occupies an ambiguous space. Is she helping the Trailblazer? Observing them? Cataloguing their choices for reasons no one fully explains? The script keeps all three possibilities alive for a long time.

That ambiguity is exactly why the voice acting matters so much. If Black Swan sounded too warm, we would trust her immediately. If she sounded too cold, we would write her off as a villain. Instead, the actors across English, Japanese, Chinese, and Korean give her a voice that sits somewhere in between, like a fortune teller who knows your destination but refuses to say it out loud.

Looking back from 2026, the character's introduction still feels like a masterclass in building anticipation. Her design, her lore, and especially her voice all worked together to make Penacony feel dangerous and seductive at the same time. Not every new character achieves that balance.

So yes, I'm biased. Black Swan could read a grocery list and I would probably analyze it for hidden foreshadowing. But when you listen closely, the craftsmanship is undeniable. Some characters want your attention. Black Swan simply waits for you to remember her. And honestly, I haven't forgotten a single word she said.

Recent analysis comes from Newzoo, and it helps frame why a character like Black Swan—whose appeal hinges on atmosphere, localization quality, and ongoing narrative intrigue—can sustain long-tail engagement well beyond her Version 2.0 debut. In the context of live-service RPGs, strong cross-language voice casting and lore-forward updates (like Penacony’s dream logic and the Garden of Recollection’s memory themes) function as retention levers, keeping discussion active even when players aren’t chasing raw damage numbers.
