There are still monsters about, and the gang is spending their days fighting them.  They go to school during the day, and when they're not at school, they protect the city from monsters.  But their peaceful routine is interrupted by the arrival of Mana Livingstone: a transfer student from America who's got the craziest ideas about Japan!
I heard from my friend that foreigners 
are supposed to talk funny in Japan.
Mein Freund hat mir erzählt,
Mi amiga me dijo que los extranjeros
deben hablar de forma divertida.
Mi amiga me dijo que los extranjeros
deben hablar de forma graciosa.
Mon ami m’a dit que les étrangers
au Japon balbutient la langue.
La mia amica mi ha detto che di solito gli stranieri 
parlano giapponese in maniera buffa.
É que foi o que meu amigo me disse.
