Is It Wrong to Try to Pick Up Girls in a Dungeon?, Vol. 12 (light novel)

And so the boy begins to run again.
Bell has grown through combat with his greatest rival.
A rank up, a denatus, a new nickname…as he draws attention from the people and deities of Orario, the young adventurer receives a letter.
“A mission…an expedition?” Bell has reached a higher level, and he must therefore take on an even more challenging adventure.
The order from the Guild leads him toward a new stage.
And so, a faction alliance sets out for the Dungeon.
Alongside his companions, Bell faces new floors, new monsters, and new unknowns.
