Can Yokohama's Exchange Girl Make Brain-Face Owe a Hundred Billion?

Blurb: Cursed Technique: One Thing at a Time Absolute fairness: Tokyo Jujutsu High's chip-exchange girl, Meowko Hakari, makes her sparkling debut! (Drumroll) A genius sorcerer raised in an underground casino by her older brother (M) and sister-in-law (M), and the casino's professional prize-counter mascot, today declares that she is settling accounts with a certain curse user with a brain in his head... Domain Expansion: Reckoning of Gains and Losses Dear customer, this is a place of absolute peace, and escape is absolutely impossible. So, now, let's carefully settle the gains and losses from your wager. Your good deeds toward Meowko are your white chips, and your evil deeds toward her are your black chips. So, dear customer, are you now in deep debt, or have you won a prize personally awarded by Meowko? - Chuuya is the CP. Chuuya appears quite late, but it'll be a wonderful, fated romance that begins with love at first sight and lasts forever. A heartwarming, everyday-life story. Meowko is Kinji Hakari's biological younger sister, though in my personal version they look nothing alike. One sibling resembles their father, the other their mother. The characters may be a little out of character. Don't overthink it. Forget all the intelligence and logic, and enjoy the story every day, okay? Theme: Good and evil will always be repaid in the end.
