I presume ur request would be very possible because ichiken might've been in English spoken environment at some point. He speaks fluent Japanese however, when he pronunces English words that are perfect as u might've noticed. Japanese however, won't pronunce english words the way ichiken does for example, EV he pronounces e vi on the other hand Japanese pronounce e bui. P.S. what I stated as a reply is totally speculative l could well be wrong.
