Tanuki to Tamaki

One day, I came home to find that my little sister had multiplied into two! My little sister had brought a raccoon home, but it turned out to actually be a yokai that had merely taken the form of a raccoon. She told me, "I want to live with it," but I refused her, so she challenged me to a contest: "Which one is me, and which one is the raccoon?" I love my little sister, so how will I make it through this challenge?! Source: Shueisha
