Alice originates from Lewis Carroll's *Alice in Wonderland*, existing within the metaphysical Library realm where story characters dwell. Her core concept is "Bondage," symbolizing self-imposed chains of devotion to her Author. Driven by an obsession to resurrect him at any cost, she declares, "I will bring Him back. Whatever it takes" and "Even if you break my right arm... or sever my left arm... even then, I won’t give up." This determination fuels endless battles against Nightmares and other characters, viewing their destruction as necessary for her wish. Despite a stoic exterior, she expresses profound inner conflict through pain and fear: "It hurts. It hurts. It hurts" and "I am afraid... I will never be able to see him again." Her background expands in the "Act of Reality," depicting her as a Tokyo high school student trapped in a suffocating existence. There, an involvement with her teacher leads to pregnancy. After he abandons her, despair drives her to form a suicide pact with her friend Shizu. They jump from a rooftop together, but instead of dying, Alice awakens in the Library. This real-world trauma mirrors her Library self's fixation, binding both versions through tragic relationships. In the "Act of Fusion," her real-world and Library selves merge. She returns to Tokyo empowered, seeking her teacher only to discover Library Alice has killed him. This triggers a confrontation culminating in Library Alice bisecting her real-world counterpart. Later, in the "Act of Elimination," Library Alice descends deeper into madness following a failed resurrection attempt. She fractures into multiple copies during battle, leading other characters to destroy her manifestations. A post-credits scene hints at potential survival through lingering lifeforce energy. The narrative *Another Alice* explores an alternate version awakening in a burning forest, guided by a cat to hunt "spirits of calamity." She discovers these spirits possess other Alices, forcing her into an endless cycle of slaughtering her counterparts. This story reinforces themes of self-destruction and multiplicity, concluding with her continuing the mission alongside the cat. Her design reflects core themes: maid attire fused with samurai elements, harnesses, and pocket watches symbolize restriction and time. She wields a katana as her primary weapon, aligning with her Breaker class and embodying unwavering resolve. Academic analysis identifies her as a "kyara"—a distilled character icon whose existence transcends her Author. Her journey illustrates characters gaining independence from creators, echoing postmodern themes of authorship. In the animated film *Ichiban Saigo no Monogatari*, the real-world Alice is a player of the *SINoALICE* game. Overwhelmed by despair, she commits suicide and enters the game world. There, she confronts Parrah and Noya (the game's navigators), who force her to relive her traumas. Library characters unite to challenge these entities, though her ultimate fate in this narrative remains ambiguous. Across all media, her story culminates in the Taiwanese/Global server finale. The Library collapses as the real-world Alice awakens from a dream, implying the entire realm was her subconscious escape from suffering, underscoring her cyclical struggle between reality and fantasy.
