The story begins not in a fantasy world of magic and royalty, but in a Japan gripped by economic stagnation. An exhausted, overworked woman at the end of her rope loses her life during the financial upheaval of September 2008. Instead of oblivion, she awakens as Keikain Runa, the destined villainess of an otome game set in a version of modern Japan. This new life comes with a noble title but also a dire predicament: her family’s prestigious Keika Group is on the brink of financial ruin, a collapse that, according to the game’s plot, will lead directly to her social downfall and destruction by the time she turns eighteen. Armed with the knowledge of her past life, including the economic history of the coming decades, she refuses to play along with her pre-written fate.

Rather than focusing on romance or competing with the game’s heroine, Runa sets her sights on a far more pragmatic goal: achieving financial independence and a quiet, slow life. At the tender age of five, she begins orchestrating complex financial maneuvers, leveraging her family’s remaining assets to capitalize on the upcoming IT bubble. Her actions successfully revitalize the Keika Group, transforming it into a massive corporate empire. However, averting one crisis only reveals another. The world she now inhabits, while similar to her own, is an alternate history where events like the Pacific War had different outcomes. This divergence means that every major economic event she remembers, from the collapse of the bubble economy to the impending 2008 crash, still looms on the horizon, ready to attack her ambitions.

The protagonist, Keikain Runa, is a striking figure, a half-Japanese, half-Russian heiress with rumored ties to the Romanov dynasty. Possessing the memories of a cynical former corporate drone, she discards the persona of a delicate young lady early on. Her primary allies are her loyal butler, Tachibana Ryuji, a holdover from her grandfather’s generation, and Ichijo Susumu, a savvy bank manager who helps execute her bold financial strategies. The narrative follows Runa as she uses her foresight to not only save her own family but to reshape the Japanese economy itself, diving into stock markets, real estate, and corporate takeovers. One notable arc involves her using her knowledge of the IT bubble in the late 1990s to amass a fortune, while another sees her preparing for the Lehman Shock of 2008, the very event that spelled her original doom.

As Runa grows, she becomes a public figure, the face of the Keika Group and a fashion leader, even winning an Academy Award for a film role, all while secretly steering her conglomerate from behind the scenes. The story is less a traditional romance and more a strategic economic thriller. The usual otome game elements, the capture targets and the heroine, are largely left in the dust as Runa throws herself into a war against the economic currents of history. Her goal is not revenge or love, but to defy the cruel destiny written for her by the times she lives in.
