Always bring a gun to a sword fight! With world domination nearly in their grasp, the Supreme Leaders of the Kisaragi Corporation--an underground criminal group turned evil megacorp--have decided to try their hands at interstellar conquest. A quick dice roll nominates their chief operative, Combat Agent Six, to be the one to explore an alien planet...and the first thing he does when he gets there is change the sacred incantation for a holy ritual to the most embarrassing thing he can think of. But evil deeds are business as usual for Kisaragi operatives, so if Six wants a promotion and a raise, he'll have to work much harder than that! For starters, he'll have to do something about the other group of villains on the planet, who are calling themselves the "Demon Lord's Army" or whatever. After all, this world doesn't need two evil organizations!

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...

Serving as mercenaries for the Kingdom of Grace, Snow and friends find themselves at war with the Demon King's army. Six launches an all-out assault...but how will his modern weapons fare against such unorthodox foes?

CHAOS VERSUS ORDER. ​After the Demon Lord Viper’s “selfdestruction,” relative peace returns to Hideout City. Now, Six and the others can turn their attention to more important matters—like how sexy their new recruit’s uniform is! But in no time at all, chaos descends yet again. The neighboring kingdom of Toris has come under the control of a new organization. When an agent of this mysterious entity starts stirring up trouble, Six and the others decide to respond the only way the Kisaragi Corporation knows how—with acts of villainy! The battle for total world domination is heating up, but will this new enemy be a match for everyone’s favorite evil organization?

It's the start of the Undead Festival, where the dead actually come back to life! Up until now, Grimm's only ever managed to die at the start of every mission and has never been useful in any way, but is this finally her time to shine?!

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!

After barging into the Piena Kingdom's holy tournament and causing a scene, Adlet was curtly jailed and, soon after, met the princess Nashetania. Though Adlet was viewed as unfit and unworthy by his fellow man, the Spirit of Fate bestowed upon Adlet the proof that he was one of the chosen Braves of the Six Flowers. But cornered by his fellow Braves who believe he is a traitor, Adlet must prove his innocence and find the true imposter before his companions play right into the enemy's hands.

Your favorite Nazarick goofballs are at it again with their hilarious hijinks! Between playing dress-up, looking for a partner for Ainz's adorable fur ball Hamusuke, and prepping for the ending theme of the second season of the Overlord anime, there's never a dull moment for these Ainz-obsessed troublemakers!

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…?

Thanks to humanity’s greatest mind, Lilith the Black, and her hypersonic anti-submarine depth charge, the pesky exploding hideout problem is fifinally resolved! Now that the Grace Branch is up and running again, it won’t be long before Lilith can return to Earth... and she intends to bring Six with her?! But fifirst, the group takes on one last job investigating the recently uncovered ruins with the help of someone they haven’t seen in a while: Patrasche Rose.
