Yumeko Jabami arrives as a transfer student at St. Dominic's Prep, an elite private boarding school where underground gambling dictates the social hierarchy. She quickly learns that the top 10 students on the gambling leaderboard form the Student Council, wielding significant power, while those at the bottom become "House Pets," forced into humiliating servitude due to gambling debts. Yumeko's secret motive is to infiltrate the Student Council to uncover which of the school governors--mostly parents of council members--were involved in the murder of her parents, all of whom were part of the mysterious "Kakegurui Club."

Early in the series, Yumeko demonstrates her exceptional gambling skills by challenging various students, rapidly climbing the ranks despite starting near the bottom. She forms alliances with Mary, Ryan, and Michael, who assist her in navigating the school's dangerous gambling culture and uncovering clues about her parents' death. Michael discovers a secret about the Student Council's control over the gambling system and informs Kira, the Student Council president, who attempts to shut down the gambling games by cutting the power to erase the leaderboard progress.

Chad, Blake's ex-boyfriend with an eidetic memory, recalls all the scores despite the blackout, allowing the students to continue tracking the leaderboard manually with chalk on a blackboard. Kira, realizing she cannot stop the gambling, decides to raise the stakes by encouraging Mary, who is ranked 12th, to challenge Yumeko in a high-risk game. The game is a test of nerve involving a blade trap where the player who keeps their finger in the trap the longest wins. Mary refuses to cheat, adhering to Yumeko's lesson to trust fate, and endures the blade nearly slicing her finger in two, ultimately winning and securing a spot in the top 10.

As midnight approaches, Yumeko remains at number 58, seemingly far from the Student Council. However, she reveals a side bet she placed on Mary making it into the top 10, which pays off, earning her $7,500. This win propels Yumeko into the top 10 just before the term ends, solidifying her position in the Student Council and increasing her influence within the school.

Throughout the season, Yumeko's gambling prowess disrupts the established order, challenging the Student Council's authority and exposing the corrupt and dangerous nature of the school's power structure. Her quest for revenge intensifies as she uncovers more about the governors' involvement in her parents' murder, leading to tense confrontations and psychological battles with other council members. The series culminates in Yumeko solidifying her place among the elite while setting the stage for further revelations and conflicts in the next season.

The ending of the 2025 TV show Bet concludes with Yumeko successfully entering the top 10 gambling ranks at St. Dominic's Prep just before midnight, securing her place on the Student Council through a clever side bet and the support of her friends. This victory sets the stage for her continued quest to uncover the truth behind her parents' death and challenge the school's corrupt power structure.

Expanding on the ending scene by scene:

As the final moments of the term approach, the tension at St. Dominic's Prep is palpable. The students have been fiercely competing in high-stakes gambling to climb the leaderboard, which determines their social status and influence within the school. Yumeko, initially ranked low at number 58, appears far from reaching the coveted top 10 spots that grant access to the Student Council and the elite retreat with the school governors.

Meanwhile, Mary, a student who had fallen to number 12, is challenged by Kira, the head of the Student Council, to take a risky gamble against Yumeko. Kira, seeking to maintain control, encourages Mary to cheat, but Mary, inspired by Yumeko's philosophy of trusting fate and never cheating, refuses. The game is a nerve-wracking contest involving a blade trap where the winner is the one who keeps their finger on the blade the longest without pulling away. Mary endures immense pain, nearly losing her finger, but her resolve wins her the challenge, propelling her back into the top 10.

As midnight nears, Yumeko remains outside the top ranks, but she reveals a hidden strategy: a side bet she placed on Mary making it into the Student Council. This bet pays off, earning Yumeko $7,500 and pushing her into the top 10 just before the clock strikes midnight. This moment marks a turning point, as Yumeko secures her position among the school's elite gamblers.

The final scenes emphasize Yumeko's cunning and determination, as well as the loyalty and support of her friends Mary, Ryan, and Michael. With her place on the Student Council secured, Yumeko is poised to delve deeper into the mystery of her parents' death, which is linked to the secretive Kakegurui Club involving the school governors.

The ending leaves viewers with a sense of anticipation for the next phase of Yumeko's journey, highlighting themes of risk, trust, and the complex power dynamics within the elite boarding school setting.

Yes, in the 2025 TV show Bet, several characters die, with key deaths tied closely to the revenge-driven plot.

• Raymond Rowe ("Ray"): Ray is a central figure in Yumeko's quest for vengeance, as she believes he is responsible for her parents' deaths. In the finale, Yumeko attempts to poison Ray at a meeting, but the poison is taken away by Kira. Later, Ray is stabbed by Yumeko with a mixer and dies. This death reveals a mystery about Yumeko's mother's fate and marks a turning point in the story, as Michael then becomes head of Ray's criminal organization.

• Blake: Blake is Yumeko's roommate and the stepdaughter of Raymond Rowe. She dies when Ray's car is bombed. Yumeko had planned to bomb Ray herself, but Michael stopped her. However, the car bombing still happens, killing both Ray and Blake. This bombing is orchestrated by Kira's father, not Yumeko. Yumeko initially feels relief that "Ray" is dead but later realizes he was not the true Ray she sought.

These deaths occur near the end of the first season and are pivotal to the unfolding narrative of revenge, power struggles, and hidden truths within the show's gambling club setting.
