On the Eastern Sea, there is an island with beautiful landscapes and abundant spiritual influence called Fuguang, or Floating Light. Three hundred years ago, a large crowd of evil spirits emerged on the island, and chaos ensued. To dispel them, the Cat God "Lan" cast spells under an ancient mountain tree. The islanders were so thankful that they built a shrine for the god underneath the tree. Since then, there has been a protective enchantment on the island, and monsters are rarely encountered. Certain cats have gained the opportunity to change into human form with cat ears and tails.
