What can we expect from next season?

So I just finished watching BES early this morning, watched it all in one sitting because I absolutely loved it, but at the end of the last episode I had a few questions. So Mizu is headed to London right? But how exactly is she going to be able to operate? What I mean is Mizu can't be as outright with her attacks as she could have in Japan, so is she going to be taking more of a ninja type role, like we've seen her do on a few occasions. I'd love to hear your guys opinions on what you think we're gonna see!
