Mocha and her two companions are adventurers for hire. Unfortunately, their quest for wealth is hampered by their inability to finish a job. Just as they are going broke, Mocha contracts to steal a mystic dragon's head from the secluded temple of fire. When the trio finally escapes with the head, it speaks, offering a fortune for abandoning the contract and taking it to a different temple. Mocha readily agrees. They soon find themselves fighting their employer to prevent the end of the world.
