In a world called the Spirit Realm, humans coexist with all kinds of spirit beasts. Through a mysterious power known as the Beast Taming Pact, humans can forge deep bonds with spirit beasts and fight and grow together. The Spirit Realm is divided into five great regions, each with its own unique spirit beasts and culture. At its center lies the legendary sanctuary of spirit beasts, the Abyss of Ten Thousand Beasts, a sacred place every Beast Tamer dreams of visiting.
