Agent Six is a powerful (but stupid) combat agent for an evil secret organization. His life takes a twist when his bosses send him to a fantasy world!

When the army needs to clear out a tower controlled by powerful demons, the only man for the job is the sleaziest, nastiest soldier they have: Agent Six!

Six's crew is tasked with the toughest job in the army: battling the forces of Heine of the flame. She's a powerful enemy, but when he gets the upper hand, there's no limits to how far he'll go…

The Demon Lord's army has invaded the city, and Rose, Grimm, and Snow can barely keep them back. Will Six help them, even if it means being a good guy?
