Rein Shroud is a special kind of beast tamer who has the ability to make contracts with unique creatures called "ultimate species" - creatures with immense strength and magical powers. Joining a party led by the treacherous Arios Orlando, Rein is released from the group in less than 6 months due to his lack of battle skills.

Little did the team know that Rein could form contracts with ultimate species, like the cat spirit Kanade. With Kanade by his side, Rein goes on an adventure to increase his rank, meeting many other powerful species along the way.
