If you’re searching for Sinon’s voice actor in Sword Art Online, the answer is straightforward: in the Japanese version, Sinon is voiced by Miyuki Sawashiro. In the English dub, the character is voiced by Michelle Ruff. The official Sword Art Online USA release pages for Sword Art Online II list the cast as “Sinon: Miyuki Sawashiro / Michelle Ruff.”
Japanese Voice Actor: Miyuki Sawashiro

Date of Birth
Miyuki Sawashiro’s Aoni Production profile lists her birthday as June 2. Public biographical references widely identify her full birth date as June 2, 1985.
About Miyuki
Miyuki Sawashiro is a Japanese voice actress, actress, and narrator affiliated with Aoni Production. She is one of the most established seiyuu of her generation, with major roles across anime, games, narration, dubbing, and stage work, and her official agency profile highlights a long list of prominent credits including Fujiko Mine in Lupin the Third, Kurapika in Hunter × Hunter, Bishamon in Noragami, and Sinon in the Sword Art Online series.
For Sword Art Online fans, Sinon is one of Sawashiro’s best-known franchise roles. Aoni’s profile explicitly lists “Sword Art Online Series — Sinon,” matching the official franchise cast pages.
Hometown
Aoni Production lists Sawashiro’s origin as Tokyo. Some public references list Nagano Prefecture as her birthplace, but her current agency profile is the strongest source for a directly documented hometown-style reference here, so Tokyo is the safest verifiable wording.
Career Highlights
Sinon is one of Sawashiro’s defining modern anime roles, especially for international viewers of Sword Art Online II and later franchise entries. The official Sword Art Online USA site identifies her as Sinon, while Aoni continues to feature the Sword Art Online series prominently in her anime credits.
Her wider career is unusually broad. Aoni lists major roles including Fujiko Mine in Lupin the Third, Daki in Demon Slayer: Kimetsu no Yaiba Entertainment District Arc, Kurapika in Hunter × Hunter, Pudding in One Piece, Kirari Momobami in Kakegurui, Hanako Koyanagi in Wotakoi, Mordred in Fate/Apocrypha, Shion Karanomori in Psycho-Pass, Bishamon in Noragami, Toko Fukawa / Genocide Jack in Danganronpa, Celty Sturluson in Durarara!!, Suruga Kanbaru in Bakemonogatari, and many more across games and dubbing.
She has also received major industry recognition. Gundam.info’s report on the 9th Seiyu Awards states that Sawashiro won Best Supporting Actress, reinforcing her standing within the Japanese voice-acting industry.

English Voice Actor: Michelle Ruff

Date of Birth
Michelle Ruff was born on September 22, 1967. IMDb lists her full birth name as Michelle Suzanne Ruff and gives her birthplace as Detroit, Michigan, USA. Behind The Voice Actors also lists Detroit and the same birth date.
About Michelle
Michelle Ruff is the English voice actor for Sinon in Sword Art Online. Behind The Voice Actors’ character pages for Sinon in the franchise list Ruff as the English dub performer for Sword Art Online II, Sword Art Online: Ordinal Scale, and Sword Art Online: Alicization, making her the English actor most closely associated with Sinon across the anime’s main dubbed releases.
More broadly, Ruff is one of the most established English-language anime and game voice actors of her era. Public profiles consistently identify her with major roles such as Rukia Kuchiki in Bleach, Yoko Littner in Gurren Lagann, Yuki Nagato in The Melancholy of Haruhi Suzumiya, Fujiko Mine in Lupin the Third, Luna in Sailor Moon, and Cream the Rabbit in Sonic the Hedgehog. Her official website and IMDb both frame her as a veteran voice actress with deep credits across anime, games, and animation.
Hometown
The clearest publicly documented location is Detroit, Michigan, which is listed by IMDb as her birthplace and by Behind The Voice Actors as her place of birth. I did not find a separate officially documented hometown listing in the sources reviewed, so Detroit is the safest verifiable reference.
Career Highlights
For Sword Art Online fans, Ruff’s key franchise role is Sinon / Shino Asada. Behind The Voice Actors’ franchise overview shows her as the English voice used most often for Sinon among English-language productions in the series’ anime releases.
Her larger career reaches well beyond Sword Art Online. IMDb and other public biographical references associate her with a long run of major anime and game roles, especially Rukia in Bleach, Fujiko in Lupin the Third, Yoko in Gurren Lagann, Chi in Chobits, Luna in Sailor Moon, Jill Valentine in Resident Evil, Yukari Takeba in Persona, and Cream the Rabbit in Sonic. That range is a big reason Ruff remains such a recognizable dub performer.
Public biographical references also note formal industry recognition: Ruff won the SPJA Industry Award for Best Voice Actress (English) for her work as Rukia Kuchiki in Bleach: Memories of Nobody. I was able to confirm that claim through public biographical summaries, though I did not retrieve the original award page directly in this pass.
Full Current Filmography
The list below is a structured, source-limited documented credits summary based on Michelle Ruff’s official website, IMDb, and Behind The Voice Actors. Because those sources differ in scope and completeness, this should be treated as a substantial public credits list rather than a guaranteed exhaustive master filmography.
Anime / Anime Dub Roles
Sword Art Online II — Sinon / Shino Asada
Sword Art Online: Alicization — Sinon / Shino Asada
Sword Art Online The Movie: Ordinal Scale — Sinon / Shino Asada
Bleach — Rukia Kuchiki
Gurren Lagann — Yoko Littner
The Melancholy of Haruhi Suzumiya — Yuki Nagato
Chobits — Chi
Ai Yori Aoshi — Aoi Sakuraba
Rave Master — Elie
The Promised Neverland — Nat
Lucky Star — Yuki Nagato-associated public role confusion appears in some summaries, so I am not treating it as a clean primary credit here
Lupin the Third — Fujiko Mine
Sailor Moon — Luna
Kakegurui Twin — Kirari Momobami
Bleach: Thousand-Year Blood War — Rukia Kuchiki
Sakura Wars the Animation — Sumire Kanzaki
Cardcaptor Sakura Movie 2: The Sealed Card — Tomoyo Daidouji
Digimon Frontier: Island of Lost Digimon — Zoe Orimoto
Akira — Kaori
WXIII: Patlabor the Movie 3 — Noa Izumi
Video Games
Resident Evil series — Jill Valentine
Persona series — Yukari Takeba, Sadayo Kawakami
Catherine / Catherine: Full Body — Katherine McBride
Sonic the Hedgehog series — Cream the Rabbit
Street Fighter series — Crimson Viper
Sword Art Online franchise — public databases strongly associate her with anime Sinon, while game-specific English casting for Sinon varies by title and is not consistently surfaced in the sources reviewed here
Animation / Other Voice Work
Spider-Man: Across the Spider-Verse — Mayday Parker
The Angry Birds Movie 2 — Additional Voices
The Bob’s Burgers Movie — Additional Voices
Live-Action / Other Screen Credits
IMDb lists Ruff with acting credits outside pure voice work as well, though her public profile is overwhelmingly centered on voice acting. The sources reviewed here did not provide a clean, fully structured non-voice chronological list robust enough to claim completeness.
Critical Reception
Ruff’s public reputation is built on longevity, consistency, and role diversity. Behind The Voice Actors highlights her as the performer behind several major fan-favorite characters, while IMDb describes her as a voice actress with credits across Akira, Haruhi Suzumiya, Street Fighter, Chobits, Bleach, Resident Evil, Sonic the Hedgehog, Persona, Sword Art Online, Gurren Lagann, and Lupin the Third. That combination of anime prestige roles and game-franchise visibility is the clearest pattern in how her career is publicly framed.
For Sinon specifically, interview coverage from The Natural Aristocrat shows Ruff reflecting on voicing the character over many years as Sword Art Online reached its tenth anniversary. That kind of retrospective coverage reinforces how central Sinon has become within her anime résumé.

Social Media
I found public social profiles associated with Michelle Ruff, including a Bluesky account and an Instagram Linktree, but I could not verify them to the standard needed to present them here as confirmed official accounts with confidence. For that reason, I’m omitting this section.
