The story is about Hale, a 10 year old boy who lives with his mother Weda in a small village in a very strange jungle. Hale's mom is a bit of a "party girl" and likes to sleep in all day and party with her girl friends all night. Things change one evening when Weda comes home with a little "playmate" for Hale, a pretty little girl named Guu. But when Hale wakes up the next morning, Guu has "transformed" into a sullen, nasty and sarcastic joker who takes great pleasure in making Hale's life utterly miserable. Guu can also swallow anything, and regurgitate it whole. Guu also seems to have various magic powers, which lead Hare to consider her a demon of some sort, but he can't convince most other people of that.
If you like comedies, this one will be your best choice. Along with Gintama, that is.
