In a vast world, a soul from another world, hailing from Blue Star, is born into this realm.
This world is home to immensely powerful magical beasts. Danger lurks everywhere, lives are devastated, and humanity's survival hangs by a thread.
Only after a human leader created a method for forming contracts with magical beasts did humanity gradually begin to thrive, recover, and grow strong enough to contend with the beasts.
Can he, a visitor from another world, survive here?
Can he become one of this world's strongest?
Can he add a powerful new force to humanity?
Come witness his growth with us…
