A box arrives at your door, but you don't remember ordering anything. when you go check it, it says 'Waifu-inator'. you open it, in it there's a ray-gun with the words 'Waifu-inator' on it. you see, there is a piece of paper. you read the paper, it says, "Just shoot it at anything you want to improve!" WHAT EVER YOU DO, DON'T SHOOT YOURSELF

What do you do with it?
