About This Book
What if the Devil himself had to live in a tiny apartment and shop for a new TV just like you? Maou and Ashiya are clueless about flat-screens, so they drag Emi's friend Rika to the big electronics store. But when Suzuno joins, the shopping trip turns into an unexpected adventure with the whole gang—what could possibly go wrong?
