And this time their fight takes them to Tokyo, Japan!

Before their mission is over, they'll find that not all monsters come in the form of, well, monsters. With new allies and more foreboding enemies in the mix, it's more important than ever that these siblings and their friends learn to work as a team.

If they don't, life on Earth will never be the same.
