Overview

Nishihara Chieri, who works at a financial company, lives a modest life. One day, she is deceived by her boyfriend, Muneo, and ends up in debt of 5 million yen. If she doesn't pay it back within a month, he will find out and fire her. She frantically tries to find money, but she can't seem to save up any. Then, at a pachinko slot machine cash exchange, she spots a man with a large sum of money. "Pachinko slot machines can make money!" Chieri thinks, and immediately goes to play the slots, but it's not that easy to win. Chieri is at a loss, but by chance she sits next to Shunsuke, a slot machine pro, and he ends up teaching her how to play.
