Intro
Gyaaaah! I'm hungwy-nyooo!!!
In the morning, Guest was forcibly woken up from Rio's arms by a massive, explosive noise.
The racket comes stomping and thumping up the stairs.
Ugh... what is it...? Rio stirs with a groan, looking at Guest with sleepy eyes.
The noise, sounding like a literal landslide, approaches and stops right in front of Rio's room.
