Alice Zuberg is one of the main characters in the Alicization Arc of Sword Art Online. She is the childhood friend of Eugeo and Kirito.

She is voiced by Ai Kayano who also voices Darkness in the Japanese version and Kayli Mills in the English version.


Alice has sparkling blue eyes, and long, golden hair that is tied to both sides of her head, and a braid running down from the back of her head, a bow attached at the end of the braid. She also wore a white lace around her forehead.

As an Integrity Knight, Alice wore white armor (golden in most light novel illustrations), a blue cape, white leather boots, and a white skirt (blue and white in the illustrations).


Alice was a determined, hard worker that aimed to master the Sacred Arts. Although her personality was serious, she was also adventurous and even mischievous, such as when she found loopholes in the Taboo Index and was willing to travel far to the Mountain Range at the Edge with enthusiasm, despite the risks.


She is the daughter of Rulid Village's chief Gasupht Zuberg. Due to breaking a clause of the Taboo Index in her childhood, Alice was apprehended by Deusolbert Synthesis Seven and taken to the Central Cathedral, where she was forced to become an Integrity Knight, named Alice Synthesis Thirty with her memories sealed.



  • In the original web novel, Alice's name after becoming an Integrity Knight was Alice Synthesis Fifty, which designated her as the 50th member to join the Integrity Knights. In the light novel, her name was changed to Alice Synthesis Thirty, thus making her the 30th member to join.
  • Alice's name coincides with the acronym of the concept of Rath's plan, Artificial Labile Intelligence Cybernated Existence (A.L.I.C.E).
  • In an official character popularity poll hosted by Dengeki Bunko for the cover of abec Art Works, Alice Synthesis Thirty ranked sixth and Alice Zuberg ranked thirtieth.
