The life of a traveling merchant is a lonely one, a fact with which Kraft Lawrence is well acquainted. Wandering from town to town with just his horse, cart, and whatever wares have come his way, the peddler has pretty well settled into his routine-that is, until the night Lawrence finds a wolf goddess asleep in his cart.

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.

Kicked out by his family and wandering the streets, an unemployed 34-year-old shut-in thinks he’s hit rock-bottom—just as he’s hit and killed by a speeding truck! Awakening to find himself reborn as an infant in a world of swords and sorcery, but with the memories of his first life intact, Rudeus Greyrat is determined not to repeat his past mistakes. He’s going to make the most of this reincarnation as he sets off on the adventure of a second lifetime!

There's a girl at their school who is always ill. She routinely arrives late, leaves early, or doesn't show up at all, and skips gym as a matter of course. She's pretty, and the boys take to whispering that she's a cloistered princess. As the self-described worst loser in her class soon finds out, they just don't know what a monster she is.

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!
