In a mythical world where God's live among men, adventurers choose a God to follow and join their Familia. Then they explore this huge, multi-levelled dungeon and kill the monsters inside to gain crystals (in exchange for money) and to help build their skills. Bell Cranel is the sole member of the Goddess Hestia's Familia and he's an adventurer of modest skill. He does have a lot of courage, heart and potential though and learns fast. He meets a woman of immense beauty and strength and vows to become stronger so he could be considered worthy of a woman like her.

There's a lot to like about this show. It has humour, action, a good plot, interesting characters and great animation. I only scored it a 7 because it's a bit 'young' for my taste (I'd have liked a darker, more serious tone) and at one season, it does seem a little pointless. I'd like to see a 2nd season to flesh things out more. Worth a watch.
