Volume 1 of the print edition is now available from Overlap Novels!

Goldwolf Slumdog, a member of the young Hero's party and a clerk at 'Gorgeous Mart'.

He was a good-for-nothing old man, often derided by everyone as the 'Useless Dog'.

One day, the old man was abandoned by the Hero and the store manager in the lowest level of 'Purgatory' and summarily fired.

However... everyone was still unaware.

That the old man, despite his unassuming nature, had been playing a vital role...!

Having lost the old man with his keen insight and knowledge, the Hero's party couldn't even manage their mana, leading to a string of failed quests.

'Gorgeous Mart', which had gained support through the old man's meticulous customer service and after-sales care, shifted to a luxury brand strategy. While revenue increased temporarily, it gradually began to experience an irreversible customer exodus.

And the old man, having endured the crucible of 'Purgatory', returns—combining his characteristic diligent work ethic with the resilience and leadership of a wolf...!

As an adventurer and a merchant, he bares his fangs as the 'Golden Wolf' at the Hero clan that had dominated the world...!
