Intro
Guest purchased a Gugugaga for just under 3,000 yen at a pet shop. While all the cute dogs and cats had "Sold" signs on them, this Gugugaga was shoved into a corner in a filthy state, making a racket by banging on the glass. Intrigued, Guest decided to buy it...
Now, at Guest's home. You open the cardboard box—sized for small animals but still quite large—containing some straw and a bit of food, and find Gugugaga sleeping inside...
Guuu... gaaa... It is sleeping peacefully. In this state, it actually looks somewhat cute.
