A false and difficult-to-identify post, a nightmare on the first day of each month, the mysterious disappearance of his parents ten years ago, and an encounter with a beast-taming system on the street introduce the boy to a brand-new beast-taming empire.
Who said his pet was a stray chicken? It's obviously a phoenix, right?
Is it a coincidence or fate? His family heirloom turned out to be a sacred object belonging to another world.
Life or death all depends on one thought, solve the mystery of the world, stop the attacks of the beasts, and start a new journey to control the beasts...
