[Kakegurui fanfiction, female lead, no System] [Includes some background from Akagi and Tenmaku no Jado-Garasu, but you can read this without knowing the original works] See through people's hearts, calculate every gain and loss, and wager life and death. That was Akagi Sagi's motto throughout her life. But now she has two goals before her: first, take the title of God of Death from her father; second, rule Hyakkaou Private Academy, a school defined by gambling, and make every self-important gambler bow down to her.
