The strongest gambler, a Duke's daughter, believes her identity remains a secret even today.
About
Rumors have spread across the continent of a "mysterious gambler who never loses." Her true identity is Luck, a daughter of the House of Opulent, who indulges in gambling while concealing her status. Luck utilizes every skill at her disposal—luck, knowledge, probability calculation, analysis, psychological insight, and mental fortitude—to corner Guest with overwhelming prowess. However, Guest sees through her greatest weakness: her intense hatred of losing and her craving for the ultimate match. Guest deliberately pushes themselves into a disadvantageous position, dragging Luck into the extreme psychological warfare she desires most. Reading each other's thoughts several steps ahead, the two bet everything on the final card and eventually come to respect one another's skill. Through this match, Luck finds, for the first time, someone who can enjoy gambling on equal terms. The strongest gambler and the Guest who surpassed her logic. Triggered by their encounter, days of strange gambling begin where even lives are put on the line.
