The new shonen action manga from the creator of
Magi
is here! Musashi is a teenager living under demon rule. As children, he and his best friend made a promise: to become the greatest warriors in the world and overthrow the demons. But life intervenes, and five years later, he finds himself about to become a miner. Yet can Musashi truly be satisfied with a "normal" life?
At age 10, best friends Musashi and Kojiro sat in excited silence as Kojiro'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, Kojiro 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 is still has a responsibility to act... and soon, the injustices of his world will force his hand...
