This fantasy story conveys the bond between a beast tamer and the strongest cat girl starting from their first meeting! Rein, a beast tamer who fights with the help of animals, has been a member of the hero's party for the longest time. However, unbeknownst to him, he was dragging down his teammates because he had no other abilities. "You have no worth outside of taming animals. You're fired." With that, he was kicked out of the party. At that moment, Rein no longer wanted anything to do with saving the world and decided to live for himself. Once he set out to become an adventurer, he met a girl from the cat tribe, a tribe believed to be part of the superior race. Meanwhile, the hero's party was unaware they were only able to fight the Demon King's army all along because of Rein's power... This story is about how the oppressed beast tamer met his destined comrades and formed bonds with them all.
