I’m Ryo. I’m a loser at pachinko, my part-time job, and life. One day, I picked up an attaché case on the street thinking there’d some money inside, but find Erika, a maidroid, instead. Since she says I’m her master and she’d do anything for me, I’ve decided to have her make money with her body. But she understands me so well that I’m falling in love with her.
