a girl and a bear and a echidna

Two agents of the mouse-run International Rescue Aid Society search for a little orphan girl kidnapped by sinister treasure hunters.

A lawless poacher wants to capture a majestic and rare golden eagle, so he kidnaps the boy who knows where to find the bird. Not to worry -- the Rescue Aid Society's top agents, heroic mice Miss Bianca and Bernard, fly to Australia to save the day. Accompanying the fearless duo are bumbling albatross Wilbur and local field operative Jake the Kangaroo Rat.

The anime follows Machi, a middle school student who serves as a shrine maiden at a Shinto shrine and takes care of a bear, who lives on mountain in Japan's northern Tohoku region. The bear, Natsu, has the ability to talk and is Machi's guardian. When Machi explains to Natsu that she will attend a school in the city, he gives Machi a set of trials that she must pass in order to be able to survive city life.
