Umm, concerning the Kagamines, the only reason they even considered giving them english banks is because Asami started learning English last year ( or the year before? ), which had no involvement with Crypton Vocaloids learning English or even Vocaloid at all, Crypton simply decided they would take advantage of this - To put it simply, her English should be just as fine as Asakawa's or Saki's English, and being a "seiyuu" has nothing to do with it, as Asakawa and Saki are also known for acting and providing character voices

Although, despite this, honestly I can't imagine the Kagamines speaking very good English, simply because their unique vocal tones will make them difficult to understand - similarly to Miku and Luka
