Alisa Cartwright, a renowned pianist poised to win Warsaw’s Chopin Competition, becomes a central figure after her abrupt kidnapping. This act drives the narrative, impacting character motivations and intertwining her with a clash over a quantum supercomputer and the Time Crystal diamond. Her unexpected personal connection to Daisuke Jigen surfaces when he betrays Lupin III to shield her, hinting at unresolved history.

A pivotal encounter between Jigen and Alisa at a piano evokes memories of her mother, implying a familial bond that fuels his protective defiance against Lupin. Though unconfirmed, this link suggests her mother’s past with Jigen underpins his loyalty, leaving their relationship’s nature—biological or symbolic—open to speculation.

Chopin’s compositions, including "Tristesse" and "Revolutionary Etude," underscore key scenes, mirroring her identity and the story’s emotional stakes. While her kidnapping and rescue propel the plot, her personal history and motivations remain unexplored, focusing solely on her role within the Time Crystal conflict.

Confined to the 2019 television special, Alisa’s narrative arc centers on the heist’s aftermath, with no expansion into other media or deeper exploration of her life beyond these events.
