DanMachi · Orario, the Labyrinth City

Layer upon layer, a labyrinth with no bottom lies under Orario's tower of Babel, and the monsters are born out of its walls one after another. Adventurers die down there every day.

But maybe, around the corner of some passage, there's a girl surrounded by monsters. A flash of steel, the monsters drop, and she looks up from the ground, her cheeks a little red. Or maybe it's the tavern waitress who always asks how today's adventure went, the elf girl being hassled by rough adventurers and waiting for someone to step in, the Amazon warrior lost on the same floor, so why not team up and keep heading down together…

Orario has never been short of people who signed their names at the Guild with that thought in their heads.
