It's a bit weird that for three years, nobody ever questions Mugi's heritage, yet when Sumire comes along, everybody assumes she's a foreigner and therefore only speaks English. I do like the idea of her being related to Mugi's butler though. Perhaps Mugi purposely left the tea sets behind as a gift to the new LMC?
And I have to say, I find the fact that Azusa was trying to copy Mio adorable.
