It certainly seems interesting from what chapters are available, but it seems like we're missing context.

Translation of the description for people who can’t speak Japanese: The king's treasure was stolen by a great wizard. The great wizard created a deep labyrinth with tremendous magic power and disappeared into the depths where he summoned ferocious monsters. The king summoned a reckless adventurer to feed on a huge reward and the chance to enter the Royal Guard, and ordered them to take back the treasure.

just an addendum using ff translate, the name in English "Magical slurring records: side by side with ashes and youth"
