Sion Bladen sealed away the Demon King and his army at Hell’s Gate. Now with the Demon King ready to rise again, Sion jumps back into battle to face his sworn enemy. Unfortunately, he ends up getting killed in a pig trap dug by farmer Touka Scott who was trying to defend himself from the demons. With no other option, necromancer Anri Haysworth puts Touka’s perverted soul in the deceased body of Sion to pose as him. Along with Touka’s childhood friend Yuna Eunice, the three mismatched heroes must rise to the challenge.
