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.
Now, now, as long as we're having fun, 
isn't that what really matters?
Ach, das spielt doch keine Rolle.
Ya, ya, lo que importa 
es que nos divertimos.
Venga ya, ha sido divertido.
Eso es lo que importa.
Peu importe, tant qu’on s’amuse !
Dai, è divertente.
È questo che importa.
Bom, tudo bem. Está divertido.
Да какая разница, если весело?
