At age 10, best friends Musashi and Kojirou sat in excited silence as Kojirou's father spun tales of evil demons who preyed on the innocent, and the warriors who defeated them. Practicing swordplay, the two swear an oath to become the strongest in the world, but as they grow up, Kojirou turns cynical, and Musashi comes to the realization that he can't overturn 150 years of demon rule on his own. He's being called a prodigy with a pickaxe, and he's almost ready to settle into a life of labor. Yet he can't shake the feeling that he still has a responsibility to act... and soon, the injustices of his world will force his hand...

Suddenly summoned to a fantasy world and betrothed to the princess, Kazuya Souma is crowned the new king after providing the royal family with impressive advice.

The world is divided into two factions: humans and monsters called katawara. Despite being a katawara, Tama loves humans and vows to protect them from evil, even if it means fighting her own kind.

When the group uncovers a plot to experiment on humans and transform them into monsters, they vow to defeat whoever is behind it... Even if it means battling an entire army of warriors.
