The plot of Kakegurui revolves around Hyakkaou Private Academy, a prestigious institution where the social hierarchy is determined by wagers. Students wager their fortunes against each other, with the wealthy and skilled wagers, holding power and the indebted becoming "pets". Yumeko Jabami, a transfer student with a love for the thrill of gambling, disrupts this established order, challenging the Student Council and its president, Kirari Momobami, who becomes intrigued by Yumeko's chaotic influence.
Yumeko: Yumeko Jabami is the main protagonist of Kakegurui - Compulsive Gambler. She's a second-year transfer student at Hyakkaou Private Academy and the classmate of Ryota Suzui and Mary Saotome. Yumeko is a member of the family of Kirari Momobami that challenges her for Hyakkaou Private Academy. Yumeko is portrayed as a very upbeat and charismatic character who consistently attracts the affection or interest of those around her, often making a big scene. Not only is she able to befriend those who previously disliked her, but she is also able to catch the attention of the entire student body. She does that on her very first day of school and continues to do so on nearly a daily basis. Every time she notices an opponent cheating in games, her button gets switched to a bloodthirsty side of her, usually seen when her eyes turn red, and she frightens her opponents.Though she is usually friendly, she abstains from acting this way when she uses her perceptiveness to expose her classmates' cheating. She is capable of doing this even after only a couple of rounds of gambling, as she is easily able to decipher what strategies and tricks they are using to skew the game in their favor. While doing this, she may unabashedly condemn the other player and their ways, preferring honesty over politeness in such cases.
