Kazuma's first winter in another world isn't going so well. With companions like Aqua (Arch-priest), Megumin (Arch-wizard), and Darkness (Crusader), his party of advanced classes should be the most powerful in Axel--but they're so dysfunctional, even the easiest-seeming quest goes terribly awry, and they can barely save enough to afford a stable! When an opportunity arises to stay in a mansion, it's like a dream come true--the only catch is that they have to exorcise the evil spirits haunting it. Goddess Aqua is an expert with the undead, so the quest should be a piece of cake, right...? Unfortunately, with this useless goddess, things have a way of working out for the worst...

Out of nowhere, devout followers decide to throw an "Aqua Festival" and Kazuma gets dragged into helping out. At the same time, Chris asks for Kazuma's help with a festival of her own. While all this is going on, Chris also ropes Kazuma into infiltrating a mansion to recover the Sacred Treasure, the "Talking Armor." Between helping out with two different festivals and tracking down another Sacred Treasure, can Kazuma catch a break...?

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!

After being transported to another world, Kazuma is joined by his allies Aqua the goddess, Megumin the magician, and Darkness the crusader. As they conduct more missions to fulfill quests, like purifying a lake while fending off monstrous alligators, they also progress as adventurers, receiving rewards from successful outings and skilling up. But one fateful day, one of the Demon King's terrifying dullahan generals approaches their sleepy beginner city. And somehow, Megumin gets his attention straight away, or should we say, earns his wrath... What are they going to do?!

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!

After successfully saving the town from Mobile Fortress Destroyer, Kazuma is ready to sit back and enjoy the hero treatment: fame, fortune, and...criminal charges?! Now in hot water with the law, he has to find a way to clear his name with the help of Aqua, Megumin, and Darkness before the judge can sentence him to death. Darkness has a plan to buy more time, but will it be enough...? After all, in this wonderful world, who knows what'll happen?

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...
