I don't have one, but it says on the site that you can only see them when you want, but they're always in your head, so you can hear them most of the time. ^-^
I'm not sure if that is a good idea. "They" (putting it in "" since it's really just you) will be sad if they aren't exactly the way you wanted them to be from the start, which is almost never the case.
That is why you should always create something new, like an OC or whatever.
