City of Hanstam to the North of Hort, a place with large cities and forests, known for its famous zoos, where they have the purpose of rehabilitating animals for nature. However, our story will take place in the old ancient Diversity Zoo, where for a long time it was a place full of life, with many employees and people who strolled through it. Now what remains are some of the most varied species of animals and a large construction of concrete and biodiversity that is about to end, having few visits compared to the time, the place no longer has a large infrastructure for to take care of toso, its security guards and keepers are already being fired by the low income of the place.

But this story, we will follow is a little red squirrel known as Kobaiashi Risu, totally energetic that always walks around the places, high wisdom when it comes to knowledge of human life. Concerns? Minimal! Everything seemed perfect, living by eating its nuts and harassing the lives of other animals. However, since then, dreams that seemed more real formulated to torment their nights, where as shown by a smaller Risu, child, running through the fields, in front of him, several beings with humanoid bodies and aspects of animals, because they had tail and ears ? For a long time it stayed in your head, was that a sign? just a strange dream? a hint? He didn't know how to describe it well, but with so many disappearances and abandonments before the zoo, why not form a group and go on great adventures after this world?

Many things can go wrong, or .... extremely right!
