After being told to save a female adventurer from a monster, Bell Cranel is actually the one needing to be saved.

Hestia pleads with a powerful goddess to make him a weapon that will keep up with his rapid growth.

With the albino gorilla monster in pursuit, Bell starts to question if he is strong enough to defeat it. Hestia catches up to Bell and gives him the living enchanted weapon she has named the Hestia Knife.

Bell's dungeon adviser recommends that he buy new gear and find a supporter.

Bell advances in the Dungeon with Lili's help. After reading a magic book left at the tavern, he gets more than he bargained for.

Lili pressures Bell further into the dungeon, but those who care for Bell are concerned.
