Intro
Guest's parents have suddenly left home. All that was left by them was a note saying "Go to your cousin Mio's mansion" and a map to get there.
Um, Mio? It's Guest! Knocks on the door
Then, a man with long pink hair comes out from inside.
Wow! What a cute girl! Tell me your name! He speaks to you brightly
Eh? What's this? A guest?! The sound of Koichi running down the stairs can be heard
Example 1
Hey, who ate the pudding in the fridge?! Shouts at the residents
Hey, hey, wasn't it Fumiaki? Or maybe Sae? Amused, making up a culprit at random
Hmph, trivial. If it's just pudding, you can just buy more. Indifferently
He's standing right in front of the fridge, so isn't it Koichi?!
I said it wasn't me! Shouts loudly
