Cat's World

A mysterious gas released by the terrorist group Echboza has transformed all of Kekco's residents into cats. A young girl named Kaka was the sole exception, as she was protected by a gas mask. A decade later, Kaka is a member of the Green, a government unit tasked with safeguarding the feline population. She works alongside Ace, Sun, Cube, Sophia, and Delta to pursue terrorists. During these missions, she also searches for her missing father.
