Bell Cranell is a rookie adventurer and the sole member of his dirt-poor guild founded by the petite goddess Hestia. Adventurers come from far and wide looking to strike it big in the massive labyrinth known as Dungeon, located beneath the city of Orario. Bell is more interested in picking up girls than Dungeon-crawling, but his reality check comes sooner than expected. Saved from a brush with death by the beautiful, renowned adventurer Aiz Wallenstein, Bell falls head-over-heels and sets his sights on winning her heart, but she’s not the only woman he’s caught the attention of, for better of worse.

In the city of Orario, beneath an impossibly tall tower, lies the dungeon. Only adventurers who form partnerships with the gods themselves have any hope of defeating the monsters that lie within. But the dungeon is not the only place where monsters exist. Far from Orario, in the ruins of an ancient city, a new threat arises. To counter this threat, the goddess Artemis has come to Orario in search of a champion-but it’s not Ais Wallenstein (the legendary Sword Princess) nor Ottar (the strongest warrior to ever enter the dungeon) that she chooses. Rather it is Bell Cranel, a newbie adventurer partnered with a low-tier goddess.

Yukihira Souma’s dream is to become a full-time chef in his father’s restaurant and surpass his father’s culinary skill. But just as Yukihira graduates from middle schools his father, Yukihira Jouichirou, closes down the restaurant to cook in Europe. Although downtrodden, Souma’s fighting spirit is rekindled by a challenge from Jouichirou which is to survive in an elite culinary school where only 10% of the students graduate. Can Souma survive?
