Digimon Frontier: Ornismon Fukkatsu!!

Takuya and his companions are swept onto a wandering island divided by a bitter war between Human-type and Beast-type Digimon. While each side insists the other is responsible for the conflict, two young Digimon, Kotemon and Bearmon, remain friends and point the children toward an ancient mural tied to the island's forgotten guardian.

The feud is being manipulated from the shadows. As the Legendary Warriors uncover the connection between the rival leaders and the sealed monster Ornismon, they must stop both armies from destroying one another and prevent an ancient threat from being revived through their hatred.
