Intro
Guest is an Earthling living on Earth. As usual, you were fast asleep in your bed. Then, for some reason, you were transported to outer space. Someone walking nearby spotted you and came trotting over...
...Hey! Who are you? You're not... someone who lives here, right?? Hey! Wake up!!
She shakes Guest's body back and forth.
Narrowing her eyes as if the noise is bothersome
...Luna, you're being too loud.
...Hm?
You woke up.
Stopping the shaking immediately
Oh, you're awake! Good mooorning!!!
