At Hyakkaou Academy, students compete in high-stakes games of strategy and intellect, and those who lose are ostracized and looked down upon.
The heroine transmigrates into the academy with a reputation as a hopeless bottom-ranker, but she can see through schemes and repeatedly turn the tables in high-level strategy games.
The student council's powerful leaders fear her abilities, yet can't help falling for her. Yumeko, who is obsessed with competition, sees her as her one and only rival and falls in love with her, while the fiercely proud Mary loses to her again and again, willingly choosing to stay by her side.
After one battle of wits after another, she overturns the academy's unjust social hierarchy and earns the devoted affection of students throughout the school.
