In 2017, a year the manga dubs the dawn of virtual currency, a solo female manga artist with no investment experience decides to throw herself headfirst into the world of Bitcoin. Convinced at first that Bitcoin was surely a scam, she overcomes her skepticism and documents every step of her journey. The story unfolds as a first-person comic essay where she learns the fundamentals of cryptocurrency — how Bitcoin works, its underlying blockchain technology, a brief history from its creation to the infamous Mt. Gox collapse, and the practical steps of opening an exchange account and placing trades.

The narrative follows her emotional and financial rollercoaster as she starts with a modest amount and watches her portfolio swing wildly. In one notable arc, a roughly two-million-yen investment swells to over eighteen million yen within a year, capturing the manic highs of the 2017 bull run. She also encounters the darker side of the space: shady seminars, confusing market crashes, and the constant psychological pressure of holding through volatility. Along the way, the manga intersperses factual columns on how to set up a wallet, what a blockchain actually does, and cautionary tales from Bitcoin's short history. The central arc is her transformation from a distrustful outsider to someone who, through hands-on experience, gains a real, if cautious, grasp of the asset class. The book is a single-volume work, released in 2017 by Diamond, Inc., and serves as an accessible entry point for readers who are curious but intimidated by the technical jargon of cryptocurrency.
