The story takes place in a parallel world called "Blue Star". Three hundred years ago, the barrier between the heavens and the blue star shattered. Countless monsters, spiritual plants, and alien races from other worlds poured in. Civilization collapsed, and the end of the world came. The surviving humans have awakened a power called "spiritual contract" - they can sign contracts with alien beasts and drive them to fight. This is the beast master.
The social status of beast masters is extremely high, but their awakening rate is extremely low (one in ten thousand), and "multi-contractors" who can sign multiple animal contracts are even rarer. It will be updated frequently, so please consider it carefully.
