Plot

Rein is a beast tamer who was expelled from the hero Arios' party who consider him too weak because he only has the ability to form contracts with animals. While looking for work, Rein rescues Kanade, a member of the cat spirit tribe who becomes his companion. By forming a contract with a member from one of the strongest races known as an "ultimate species", Rein obtains some of her powers, becoming much stronger. The two then begin their journey together, with Rein befriending and taming other girls from different races who become powerful companions while obtaining new abilities with each new contract formed, his group eventually becoming far more powerful than Arios and his party. Overcome with anger and frustration, Arios begins loathing Rein, neglecting his duties as a hero and focusing on revenge against him and his friends instead.
