Luck be a lady tonight!Seeking financial support in the fight against the Demon King’s army, Princess Iris visits the neighboring nation of Elroad to meet the prince: her husband-to-be. But Kazuma won’t hand over his little sister to just anyone! Scratch that. He won’t hand her over, period! Posing as her escort, he tags along in an attempt to derail yet another wedding (and rake in the dough). But no sooner than they arrive in Elroad are they informed that the engagement is off, and there won’t be any financial support at all! And so it falls to Kazuma to use his wit and insanely good Luck to milk the Casino Kingdom for all it’s worth!

After a rocky start, Iris is getting along with Kazuma splendidly, and she's even taken a liking to our hero and his boorish ways. Claire, however, is still not impressed, and she wants him as far away from the princess as possible. But Kazuma's grown attached to his new little sister, and no matter how low he has to sink, he's determined to do whatever it takes to stay by her side!

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 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!

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?!

GOD’S BLESSING ON THIS POPULAR NEET!There’s a new girl in town! And for some reason, she keeps calling Darkness “Mama.” Surely there’s a perfectly reasonable explanation for that...right? Meanwhile, Darkness has taxes to collect! It’s time for the high-income adventurers to pay their dues, and Kazuma’s at the top of the list. Naturally, one night after a long game of Cat and Mouse: Tax Evasion Edition, they find themselves handcuffed together, and Darkness sees it as the perfect opportunity to ask Kazuma a burning question: “...Do you like Megumin?”

ETERNAL LIFE CAN GET LONELY There’s a stalker on the loose! …Or so it would seem. Apparently, Wiz has been receiving a lot of attention from a mysterious man. After some eavesdropping reveals the terrifying extent of his knowledge about her, she receives a letter requesting they meet. And when she brings it to Vanir and Kazuma, Vanir gets unusually worked up and threatens to take action! This gives Wiz the push she needs to handle the issue herself…but it looks like someone has been filling her head with weird ideas. For starters, why is she acting like a blushing bride to be?!

P.S. PLEASE LOOK FOR ME. With Serena’s sudden rise in popularity, Aqua’s insecurity sends her fleeing from town, leaving only a letter behind. If they no longer need their goddess, then Aqua won’t stay where she isn’t wanted! She’ll beat the Demon King by herself, save the world, and return to the heavenly realm! Little does she know, though, that the people of Axel are nothing without their beloved mascot—not that Kazuma plans to do anything about it. He’s only Level 1, after all. Oh, who is he kidding? With this latest development bringing him straight to the Demon King’s castle gates, it’s time for Kazuma to rally the troops, power-level like never before to awaken his hidden potential, and get his goddess back!
