The manga will center on Mashiro, a second-year middle school student who loves to shop. She finds a "lucky bag" of random clothing at a Western-style clothing store that says the contents inside are worth 30,000 yen (about US$227) but is being sold for 3,000 yen (about US$22.70), so she buys it. She's excited to see if she ended up with a good deal, but it doesn't seem that way, and she wonders why. The manga will help to teach "lessons about money that you won't learn at home or at school."
