Given that Ayu hasn't really lived overseas for a significant amount of time, I don't think her English proficiency is terrible by any means. Even if her partner speaks a differentiating language, it isn't as if her entire environment also commits to that language, and that is the major method of learning a language swiftly. Moreover, it isn't as if she is attending an institution of education (like international students are exposed to), and so her lack of interaction with people with a greater emphases on her proficiency (i.e. having to hand an assignment in, or give a group presentation in English) would disadvantage her also.
I'm not sure how proficient her staff are in English, but given that she takes Timmy everywhere with her, perhaps she doesn't have to use a lot of English overseas as her staff organise many of her activities and events for her?
