Sekine invites Chiyo to a sleepover at her house, and the other two invite themselves as well. They deepen their bond while Rikka learns more about the quirky cultural activities that take place on Earth.
She must have passed out 
from the surprise.
Bist vor Schreck glatt ohnmächtig
geworden, was, Rikka?
Debe haberse desmayado del susto.
Debe de haberse desmayado del susto.
Elle est donc tombée de surprise !
Parce qu’en fait…
Rikka deve essere svenuta per la sorpresa.
Ela deve ter desmaiado de susto, né?
Видимо, упала от удивления.
