After a career spent slapping down superheroes as an evil minion of the Kisaragi Corporation, Agent Six has his next assignment-invade a fantasy world! With his pluck new partner, the "pretty-girl android" Alice, Agent Six sets out to bring his target planet to heel. What better way to accomplish that than by partnering with the locals?! Alongside Royal Guard Captain Snow, Battle Chimera Rose, and Archbishop Grimm, Alice and Six will square off against demon hordes-even if it's just a means of taking down the competition! Let the battle to be baddest begin!

The evil Kisaragi Corporation's spy, Agent Six, has successfully integrated into one of the Kingdom of Grace's commando units! While his approach to heroics is...unconventional, his combination of modern weaponry, outside-the-box thinking, and ruthlessness has made his squad of misfits into one of the kingdom's greatest assets in the fight against the Demon Lord. This time, it's up to him, Alice, Snow, Rose, and Grimm to capture the impregnable Tower of Duster and face off against Heine of the Flames once more in an all-out battle...

Agent Six's utterly unchivalrous tactics had been working wonders, but that all comes to an end when he and Alice are outed as spies and banished from the kingdom of Grace. How unfortunate that the Demon Army is preparing for all-out war at that very moment... Six might still be able to save his feckless former squadmates from certain doom-but only if he's willing to gain an unfortunate nickname in the process!

A month has passed since the cease-fire with the Demon Army, and now that the teleporter is online, Kisaragi has sent a mutant to help the invasion get back on track. But the evil organization’s plans are derailed once again when Six is dispatched on a diplomatic mission to relieve the kingdom of Grace’s terrible drought—a problem he caused by changing a rainmaking artifact’s password into something that can’t be printed on the back of a book. Is Six really the right man for the job…?
