The heroine of the series, Alice first appears as a chain that persuades Oz to form a contract with her in the Abyss. In fact, she is actually the infamous B-Rabbit (Bloodstained Black Rabbit), the strongest chain in the Abyss. Alice's goal is to find her lost memories, which play a major role in the story. In human form, Alice has long dark brown hair with 2 side plaits. She has a huge appetite and loves meat especially. She is hotheaded, loud spoken and says what she thinks without regard to the consequence. Despite this, she has a soft side, especially when Oz is involved. She hates when Oz leaves her alone, but to hide it she usually says, "I'm in a contract with you. You are my manservant, and as a manservant, what were you thinking, leaving me behind!?" or she just hits Oz and says, "Shut up."

According to Jack Vessalius' diary, Alice looked like a normal girl but was kept in a tower by Glen Baskerville. Initially, Jack did not understand why Alice was imprisoned until he noticed something odd about her. Her cat (Cheshire) had various attitudes towards Alice from time to time; once it would stay in Alice's lap and another time it would not go near her and would even hiss at her. Eventually, Jack and Alice's conversation would not connect and her answers would always be different. Even her personalities (i.e. favorite book and favorite color) changed many times. One day, Jack confirmed his suspicion by asking Alice who she was, since the current "Alice" wasn't the Alice he knew. "Alice" admitted this but stated that she and "that brat" were still "Alice" and that their "souls" are linked. Jack then concluded that Alice and the Intention of Abyss were born at the same time in the human world and Abyss and that they are twins.

It's revealed that the Will of the Abyss and Alice are twins.
