Chiya learned from her animal friends that you have to bare your belly when you apologize. That custom doesn't translate so well to city life.
This is pure cute-girls-do-cute-things comedy. The cute thing is fortune telling. The cute girls are cute! Chiya's belly button is going to be a running joke. The animation style and quality tiers fit the tone and gags. It's a nice fluffy relaxing show to watch.
The four main characters all become fast friends of Chiya the wild child. Kon, who is not a fox girl, is serious. Koume likes Western Culture. Shy Nono uses a ventriloquist doll to tell fortunes.
I don't know what fortune telling skills Chiya has yet, but she's definitely good at making friends quickly.
