Helck 2.

After the Demon Lord is slain at the hands of a lone human warrior, humans rejoice over the end of his reign of terror.

How will Helck change the course of the war between demons and humankind?

Helck sets out with a group of demons led by the disguised Vermilio to defeat a mysterious group of winged soldiers and reclaim Castle Urum. However, before they can finish the fight, Helck and Vermilio are transported to a strange place. Now, the two must figure out how to survive in this new environment…and how to coexist!
