Rein, a Beast Tamer who commands animals, has fought as a member of the Hero's party. However, with no other discernible talents, Rein gradually falls behind in combat. "You're useless, only commanding animals. You're fired!" Ultimately, Rein is banished from the party.

"From now on, I'll live freely, no longer concerned with saving the world." Rein decides to become an adventurer, but... at that very moment, he has a fateful encounter.

Meanwhile, the Hero's party was unaware that their ability to fight the Demon Lord's army until now was largely thanks to Rein's power.

This is the story of a downtrodden Beast Tamer who, after a fateful encounter, forges bonds with true companions.
