The story is set in an alternate version of Wonderland, where the protagonist, Alice Liddell, finds herself entangled in a world governed by the enigmatic and unpredictable Joker. This trilogy delves deeper into the darker, more surreal aspects of Wonderland, exploring themes of identity, loyalty, and the nature of reality.

The narrative begins with Alice being transported to the Country of Joker, a twisted version of Wonderland ruled by the titular character, Joker. Unlike previous iterations of Wonderland, this realm is characterized by its chaotic and nightmarish qualities, where the line between dreams and reality is blurred. Joker, a figure of both charm and menace, serves as the central antagonist, manipulating events and people to maintain his control over the land. His motives are ambiguous, and his interactions with Alice are laced with a mix of fascination and cruelty.

Alice, the central protagonist, is portrayed as a strong-willed and introspective character. Her journey in the Country of Joker is marked by her struggle to understand the rules of this strange world and her place within it. Throughout the trilogy, Alice forms complex relationships with various inhabitants of Wonderland, including familiar characters such as the Mad Hatter, Blood Dupre, and Boris Airay. These relationships are fraught with tension and ambiguity, as each character has their own agenda and connection to Joker.

The plot is driven by a series of events that challenge Alice's perceptions and force her to confront her own fears and desires. The first part of the trilogy introduces the setting and establishes the central conflict, with Alice attempting to navigate the treacherous landscape of the Country of Joker.

The supporting cast plays a crucial role in the story, each contributing to the intricate web of alliances and betrayals that define the Country of Joker. The Mad Hatter, for instance, is a key figure whose loyalty to Alice is tested by his own dark past and his complicated relationship with Joker. Blood Dupre, the leader of the Hatter Family, is another significant character whose interactions with Alice reveal layers of vulnerability beneath his tough exterior. Boris Airay, a playful yet dangerous figure, adds an element of unpredictability to the narrative, often serving as a wildcard in the power struggles that unfold.
