The imperial court proclaimed that whoever could tame the mythical monsters would be richly rewarded with status and wealth. An organization to fight the beasts, the Beast-Subduing Department, was established, and a hero ranking list was created.

And so the humans battled against the mythical beasts, all of whom served their own masters.
