Yumeko Kawamoto was never meant to stay. A reckless transfer with a taste for chaos, she was sent to St. Dom's on a dare - to make the Ice Queen herself fall, to shatter the unbreakable. Kira Timurov rules that academy with silence and precision. Untouchable. Unshaken. Until Yumeko-too loud, too charming, too dangerous-becomes the only person who sees her, who dares to touch her. What begins as a game of dares and domination spirals into something neither of them can name. Obsession. Desire. Something that burns. But behind Yumeko's wild smile hides a secret: this was never supposed to be real. And when the truth comes out, the only question left will be- Was any of it ever real? Or was love just another wicked game?

All or Nothing | Zenbu ka zero ka (全部かゼロか) Yumeko Kawamoto-the girl who arrived without a past, yet instantly drew every eye. St. Dominic's Prep was a playground for the rich and entitled, where elegance masked corruption, and power was won not through grades-but through gambling. No one could quite figure Yumeko out. She was a paradox-bright and bubbly one moment, cold and unreadable the next. She could charm a room with a smile, yet keep her true intentions hidden beneath layers of mystery. After making a shocking and powerful impact at St. Dom's, her existence and gambling play spoke a word to everyone and it spread like wildfire, making it reach the student councils. 'How does she do it? What does she want?' That's exactly what the president of the student council asked herself. Kira Timurov. A Ruthless, strict, and composed ruler of St. Dominic's Prep. What exactly awaits for St. Dominic's Prep when the unstoppable force of Yumeko's gambling skills and Kira's ironclad rule collide? WARNING! This story is inspired by Bet AND Kakegurui anime. I do not own any of the characters except from my own made ones in this story. feel free to express yourselves in the comment section! It's a safe space!

Heaven was something unfamiliar to Yumeko. At least, that's what she thought before she chose to lose it to the flames. Only she did not know it until it was too late. When she finally gets another chance to paradise, she doesn't plan to ever let go. ~•-•-•-•-•-•-•-•~ *Vampire Yumeko *Reincarnated Kira

At St. Dominic's Prep, power is everything-and it's won through gambling. Games decide status, freedom, and future. Wealth, reputation, manipulation-they're the true currency. Ruling it all is Kira Timurov, the cold, flawless Student Council President. She doesn't bluff-because she never loses. Emotions? Useless. Until her father, the school's secret benefactor, gives her one condition: "Find someone who truly loves you-or lose your claim as heir." Furious, Kira turns love into a game. She'll fake it. Manipulate it. Win, as always. Then comes Yumeko Jabami-a beautiful, thrill-seeking transfer student who gambles for fun, not power. She's chaotic, fearless, and utterly unpredictable. Their first encounter? A reckless bluff in front of the entire school. Yumeko loses-then laughs. And for the first time, Kira's perfect mask slips. Yumeko is wild. Mysterious. The perfect pawn. But as the fake romance deepens and the games grow dangerous, Kira faces something she can't control: Real emotion. And Yumeko? She doesn't fake anything. Or Your fake-dating au.

Yumeko uncovers the chilling truth behind her parents' deaths-while the assassin was a man named Ray, the true masterminds were the elite school board members of St. Dominic's. Her parents, once loyal council members, were eliminated for daring to use the Kakegurui club's dirty money for good. Fueled by a deeper need for justice, Yumeko poisons Ray, only to be shattered by his dying words: her mother may still be alive. As her quest shifts from vengeance to uncovering the truth, Yumeko forges an unlikely alliance with Kira, a former rival with her own scars and ambitions. Bound by shared enemies and fractured pasts, their partnership grows into something deeper-something dangerously close to love. Together, they just might have the strength to take down the system that broke them and rewrite the rules of power, justice, and fate.

This fanfic is dedicated to all fans of Kira and Riri. I decided to stray a bit from the canon( it's about Kira&OFC and Riri&OFC), so I want to focus on the relationship between the main character and the Timurov sisters. By the way, the main character can be seen as a self-insert, but I gave her a name and backstory, since I'm not a fan of the typical Y/N fanfics. P.S. If you're a devoted fan of the Mary/Riri pairing, I'd recommend skipping this story - they won't be explored here;)
