Guardian Heroes

Ages ago, the spirits of Earth and Sky waged war on each other. Neither could win, and eventually the Sky Spirits bestowed some humans with their powers, turning them into wizards and allies in the war. The Earth Spirits were banished into darkness; but the Sky Spirits feared the human wizards and cast them underground as well. Years have passed, and a powerful wizard named Kanon escaped from the gloomy prison and turned the human land into a puppet state trembling before his might. One legendary sword is said to bring an end to Kanon's reign. Four warriors (Han, Randy, Nicole and Ginjirou) retrieved the sword, but knights sent by Kanon are determined to take it away and destroy it at all costs. Aided by the renegade knight Serena, the four heroes must keep the world safe and protect themselves against the onslaught.
