"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? A (DOG'S) HEAD CAN STILL BITE The Uesugi black-plates are back in action after Kuroko defeats Seiroku in a clash of wits and Kanetatsu breaks his blade. Yet, the Black Dogs are far from finished! The battle enters a new phase as each side's greatest fighters square off- Kanetatsu vs. Seiroku, and Naotora vs. Shiro. Meanwhile, Musashi and the other samurai make a desperate dash toward Yamata no Orochi."
