The story begins with a group of endangered Italian wolves in the Apennine Mountains.
After a raid on the Fiore Mountain Villa in Peru at the foot of the mountain, the shepherd Liu Daosu = =|| was forced to go up the mountain to search for traces of wolves. In the mountains, he met Hibari Kyouya, the leader of the wolf tribe who can transform into a human.
Skylark, who hates humans, spared the humans who invaded the valley.
The reason goes back to Skylark's childhood experience.
Immediately afterwards, gray wolf Dino, orange wild cat Tsuna, and companions Jokudera, Yamamoto, etc. All appeared.
In the conflicts between humans and wild animals, there is always farce, because the deformed animals have endless tricks. Liu Daosu finds himself more and more concerned about Hibari Kyouya. On one side is Bai Lan, the leader of the Apennine Mountains, who threatens to conquer the Apennine Mountains, and on the other side is Hibari who may be killed by humans at any time.
The bond between humans and animals gradually deepens. Racial differences and competition for survival threaten everyone.
At a critical moment, an even more unexpected and huge family of animals also appeared...
