What is “Kamiyain Fumi wa Bakuto ni Naritai!” About?

The story is set in a near-future Japan where a shocking new law has passed: underage gambling is completely legal.
The protagonist is Fumi Kamiya-in, a first-year middle schooler who fancies herself a master gambler (bakuto). Her entire persona is built on shallow, second-hand knowledge she’s picked up from novels and manga. She loves to act high and mighty, showing off her supposed “genius” to her unsuspecting classmates.
However, Fumi’s “poser” attitude soon gets her into real trouble. A friend, who has racked up a serious debt to a university student, begs Fumi to act as a substitute player (da-uchi) to clear the debt.
Despite her grandiose posturing, Fumi knows she’s just a regular middle schooler and feels the pressure is way too much for her to handle. But when she’s flattered and praised as a “veteran substitute player,” her brain is flooded with a massive rush of dopamine. Addicted to that feeling of validation, she recklessly agrees to the high-stakes match.
“Fumi Kamiya-in Wants to Be a Gambler!” is a “fighting mahjong girls’ comedy” that masterfully depicts the story of “girls whose brains have been fried by the addictive, speculative thrill of mahjong.”
