After dying during the chaos of the 2008 financial crisis, an ordinary office worker awakens as Keika-in Runa, the young villainess of an otome game — and the heir to one of Japan's noble families. There's just one problem: Runa knows exactly what is coming. The global financial crisis. Japan's economic collapse. Political upheaval. And the disasters that will eventually threaten everything her family has built.

Determined not to meet the villainess's doomed fate, Runa begins manipulating markets, investing in emerging technologies, restructuring her family's businesses, and building an economic empire years ahead of schedule. But changing the future proves far more complicated than she expected. As Runa's actions begin reshaping Japan itself, she finds herself caught between powerful corporations, politicians, foreign interests, and the unpredictable consequences of a future that no longer follows the script.

"Yet this isn't a story of my conviction. This is a story of my — no, our — revenge on the age in which we were born."
