The 26 episodes center on protagonist Nao Kanzaki and ex-conman Shinichi Akiyama as they compete in the Liar Game Tournament through concrete mechanics such as Minority Rule voting, contraband smuggling rounds, and poker variants. Every plot point revolves around alliances, betrayals, and psychological tactics rather than any external ideological framework. Creator Kaitani stated the story counters victim-blaming narratives around fraud by emphasizing personal responsibility and the value of trust, with no activist messaging attached.

A supporting transgender character from the manga source appears in Round 2 material and functions as an opportunistic manipulator, yet remains peripheral to the central game strategy and moral dilemmas. The absence of identity politics or systemic critiques keeps the focus strictly on individual cunning and human nature.
