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?
