The Charm of Soul Pets.

The main character, Chu Mu, was the heir to the Chu Clan, but he was banished to the island and faced an almost certain death as a result of a planned assassination. He danced on the brink of death, fighting for his life with a little Moonlight Fox he had captured. He had to exhale when he was finally free of the demonic foremen on his island. However, he was unaware that this was just the start of his destined trip with his tiny Moonlight Fox.
