After the Demon Lord is slain at the hands of a lone human warrior, humans rejoice over the end of his reign of terror. But an intense tournament of powerful fighters hoping to be crowned the next Demon Lord has drawn in the unlikeliest of contestants--Helck, who claims to hate humans but is one himself! How will Helck change the course of the war between demons and humankind?

Helck continues to lay bare the harrowing tale of how he became the mighty--and disgraced--hero he is today. In the past, after his brother, Cless, sustained near-fatal injuries during an encounter with the Demon Lord, Helck set out to the Demon Lord's castle in his stead. But what awaited him was a shocking revelation about demonkind that no human could ever comprehend.
