Yumeko Jabami - Kakegurui

Yumeko Jabami (蛇喰 夢子) 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.

Despite the disadvantage she faces when others cheat, she does not concede. This is mainly because she does not seem to experience any fear or anxiety from taking risks; it gives her a thrill. Because of this, she tends to take high-risk bets in gambling, even if she has nothing to rely on but luck. Though this can sometimes end in her loss, she is emotionally unaffected by the results; she simply uses her losses or gains as a means to further indulge her gambling habit. She also wants to make her friends feel the same rush as she does. So, while her pushing them into risky gambles might seem irresponsible, she means it well.

She seems to be quite aware of her eccentricities and that her way of gambling doesn't follow normal conduct. As such, she rejoices when people support her or encourage her, especially those close to her, greatly valuing their friendship, albeit
