Miss Kobayashi was growing accustomed to her new life with Tohru, and so they headed out to go shopping together. She's surprised by Tohru's social skills though, when she sees how friendly Tohru was with the people of the shopping district. However, Tohru herself makes the dark claim that she's only pretending to be friendly, and shows how she still doesn't understand human emotions. Then on one of her days off, someone calls at Miss Kobayashi's home. She opens the door to find a little girl with horns and a tail--?!
So you can't trust anyone 
in an unknown world?
ألا يمكنكِ أن تثقي بأحد في عالمٍ مجهولٍ إذاً؟
Du kannst also niemandem aus
einer unbekannten Welt trauen?
¿No confías en nadie
en un mundo desconocido?
¿No te fías de nadie 
en un mundo desconocido?
C’est normal de se méfier,
dans un monde qu’on connaît pas.
Non ti fidi di nessuno 
in un mondo completamente sconosciuto?
Então não confia em ninguém
 de um mundo desconhecido?
Никому не можешь довериться в чужом мире?
