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.
"Never show your back to anyone."
Sie wendet niemals jemandem den Rücken zu,
das hat sie sich ankonditioniert.
Ne jamais tourner le dos
à qui que ce soit.
Non mostra mai le spalle agli altri,
 in nessuna circostanza.
"Nunca mostre suas
costas para os outros".
Ни к кому не поворачивайся спиной.
