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!
