If you’re searching for Alice’s voice actor in Sword Art Online, the answer is clear: in the Japanese version, Alice is voiced by Ai Kayano. In the English dub, the character is voiced by Kayli Mills. The official Sword Art Online Alicization cast page lists “Alice — Ai Kayano / Kayli Mills.”
Japanese Voice Actor: Ai Kayano
Date of Birth
Ai Kayano was born on September 13, 1987. ORICON’s profile lists her birth date as 1987/9/13 and her origin as Tokyo.
About Ai
Ai Kayano is a Japanese voice actress affiliated with Office Osawa. She is one of the most recognizable seiyuu of her generation, with major roles including Meiko “Menma” Honma in Anohana, Inori Yuzuriha in Guilty Crown, Mashiro Shiina in The Pet Girl of Sakurasou, Shiro in No Game No Life, Darkness in KonoSuba, and Alice Zuberg in Sword Art Online: Alicization. ORICON and IMDb both identify those as part of her best-known career profile.
For Sword Art Online fans, Alice is one of Kayano’s signature franchise roles. The official Alicization cast page names her as Alice’s Japanese performer, and the War of Underworld character page also lists Alice’s voice as “Ai Kayano / Kayli Mills.”
Hometown
ORICON lists her as being from Tokyo, Japan.
Career Highlights
Alice Zuberg is one of Kayano’s most visible international roles, especially because Alicization turned Alice into one of the franchise’s central heroines. Official franchise pages consistently credit Kayano as Alice in both Alicization and War of Underworld materials.
Beyond Sword Art Online, Kayano built a strong reputation through lead and heroine roles across many hit anime. Public profile sources consistently highlight Anohana, Guilty Crown, No Game No Life, Saekano, The Pet Girl of Sakurasou, and KonoSuba among her defining works. ORICON also notes that she won the Rookie Actress award at the 6th Seiyu Awards in 2012.

Hometown
I found public references placing Mills’s origin in Michigan, but I did not find a clearly stated hometown on her official website in this pass. Because of that, Michigan is the safest verifiable location to cite here.

Her wider career spans anime, games, music, and adaptation work.
