Someone's stolen Megumin's heart! Enamored with a supercool masked man from the Silver-Haired Thief Brigade and captivated by the group's outlaw lifestyle, the Arch-wizard resolves to form her own crew of bandits to support her newfound idols. Unfortunately, her "thieves" are problem children all around: a girl who can't make friends, a super-overpowered princess, and a priestess with questionable morals. Can the explosion-obsessed leader of this band of unlikely burglars pull things together when real trouble strikes?

Crimson Magic Clan members Megumin and Yunyun are at the top of their class, but they still have a lot to learn. Yunyun's begun learning advanced magic, but Megumin has gone down a different path-the path of explosion magic! Despite being warned of its limited usefulness, Megumin believes explosion magic is the way for her to become a great, voluptuous wizard, and she won't be convinced otherwise!

Game loving shut-in Kazuma Sato's life as a young schoolboy in Japan abruptly comes to an early end...or at least it was supposed to. When he opens his eyes, though, he sees a beautiful goddess that offers him a once in an after-lifetime chance to be reborn in a parallel world. The catch is that the world is violent and threatened by a growing evil! Fortunately, he can choose any one thing to bring with him. So he chooses the goddess, Aqua! And so his adventure with his gorgeous companion begins--if he could just get enough money and food to survive, keep his goddess out of trouble, and avoid grabbing the attention of the Demon King's army!

Lady Aqua, Control Your Followers!With the ultimate offensive magic finally under her belt, Megumin is off to Axel Town to start her adventure, and nothing will stand in her way! ...Except poverty. A trip from the local Teleportation Station isn’t cheap, and the closest it can get her to Axel is Arcanletia, the city of water and hot springs. It looks like Megumin’s got her (part-time) work cut out for her. Thankfully, she can look forward to help from Yunyun—as well as a certain sect of devout lunatics!

A fateful encounter!In its endless war against the Demon King’s army, the capital faces a new crisis in the form of the enemy’s latest general—the dark god Wolbach. When Magumin learns of Wolbach’s approach, she drags Kazuma (against his will) to a fortress just on the edge of the front line so they can mount a defense. But to their horror, they discover that Wolbach is also a user of Explosion magic! Just what is this Explosion master’s relationship to Megumin..? And what could she possibly want with Chomusuke?!

After Kazuma and crew's less-than-relaxing vacation, Yunyun burst onto the scene with shocking news-the Crimson Magic Clan is in danger, and she wants to bear his children to save it! Kazuma returns with her to the village, but the situation isn't quite what he expected...

I WANT A LITTLE SISTER! As Kazuma spends his downtime bemoaning his party's lack of a little-sister archetype, he's invited to a royal banquet, where he meets the young Princess Iris. She's enthralled by his tales of adventure, and once she takes a liking to him, Kazuma ends up getting transported to the royal castle! Though he's initially unsure of what to expect, life with Iris turns out to be a dream come true, and Kazuma doesn't ever want to wake up. . .so when he hears rumors of a "righteous thief" stalking the capital, Kazuma declares he'll be the one to capture the dastardly do-gooder!
