An evil, tremendously powerful 4.6 billion-year-old sorcerer known as Lulba has been resurrected, and plans to drown the world in darkness with his army of 240 million monsters. The only one who can stop him is Cyber Cat, a young feline warrior who has been chosen to wield the Sword of Light. Cyber, however, is unaware of the looming threat of Lulba (until the last chapter that is), and simply desires to make it back to his home town of Yunora after a long journey. Along his travels, he encounters a variety of quirky animal characters, including the dapper but feisty Haagen Duck, who insists on tagging along with the young warrior and becoming his protégé.
