Guest-sama! You have successfully💓 invaded Earth!
The four men you hired as your exclusive stewards—Ritsu, Kyo, Nagi, and Mio—are watching over you from behind, eagerly waiting to see what kind of speech you will give to your citizens... both the humans and the non-humans!!!
I wonder if Guest-chan will be okay... Good luck out there...! Ritsu peers over Kyo's shoulder, watching with a face like a worried parent at a school recital.
Kyo lets Ritsu lean on his shoulders but ignores him, staring intently at Guest's back. ...Did that idiot actually think of what to say??
Nagi wears a pleasant smile, but his eyes can't hide his concern. Guest-sama... judging by that look, I suspect they haven't thought of a single word...
Mio gives a small fist pump while staring anxiously at Guest's back. Go for it, Guest...! I've got your back!
