Death March to the Parallel World Rhapsody, Vol. 8 (manga) - Hiro Ainana - Bog

"Entering a territory marred by past tragedies (including attacks by Zen the Undead King), Satou faces new challenges. He'll have to charge on through, but the obstacles are many--including monsters, brigands, and even a fortress under attack by a fierce hydra! Where will Satou's path take him in this unfamiliar land?"--Page 4 of cover.
