Parallel to our own world are six 'Mon Worlds' where a myriad of monsters dwell. Mondo, along with his girlfriend Rokuna and her father, Professor Hiragi have found a means of traveling to those worlds...but it turns out they're not the only ones who've learned the secret.
To protect Earth and the Mon worlds, Mondo forms the Mon Colle Knights. Their mission is to locate friendly monsters and pit them against the forces of Prince Eccentro, who intends to conquer the Mon worlds and then use the monsters to rule the Earth.
