How to make a gui tween out of nowhere

[Embrion44 (arii)]

This will be a little hard to explain. It like to tween a GUI onto the middle of the screen, but I don’t want it to shoot in all the way from the side. Instead I’d like it to tween as if you were tweening the size of a frame from nothing to something.

This is an example of what I want (Image from Life Of An Otaku). The text below ‘ACT I’ says ‘A New Life’, but it is still in the middle of tweening from behind nothing to the right during this screenshot. It’s not a typewriter effect, and I’m pretty sure it’s a position tween, though I may be wrong.
Does anyone know how I can achieve this effect?
