There's no rule saying that UTAUs absolutely have to have a real name. Make it into anything you want it to be because it's yours. //Totally not saying that you can 100% anything you want like for example naming it after an already existing VOCALOID. There's nothing you can do if it's like some other UTAUs name since there's thousands upon thousands of them on the net unless you purposely take the name but I'm pretty sure you knew that already. (ˊ˃ॣ~˂ˋॣ) My UTAUs surname isn't real. All I did was take the japanese name for monkey and wolf and stick them together which I regret from this day because tbh that's just silly, haha ;7; What's done is done, y'know? So, ah, do what you think fits best!
