I feel like the timeskip jumps over a period that could have been a really interesting arc. Just imagine if the kids had to plan and figure out different ways they could infiltrate a demon city, create maps, and learn how to pass as demons if they were confronted. Perhaps the villain of the arc could be a brutal demon policeman who make sure order is kept in the markets. Then when that arc ends and the Ratri clan find the kids it would be even more shocking. It's not as though the whole thing is necessary to the story, but it would have been an interesting way to learn more about the demons and more about the Goldy Pond kids. So what do you guys think?
