The Anime Lad
Kinji invested his way into a comfortable life without employment. Another world interrupts that arrangement and gives him debt instead. He is sent into a dangerous mine controlled by a ruthless company. Since physical labor conflicts with his values, Kinji begins searching for less reputable routes back to comfort.
Super Eyepatch Fox
Achieve financial independence. Get transported into a fantasy economy with debt. Enter a mine where corporate demands shape daily survival. Kinji has no interest in becoming a noble worker, so The Dungeon of Black Company builds its comedy around shortcuts and schemes. Schemes replace heroism.
Gigguku
Kinji has already escaped work through investing, so another world hands him debt and a mining job. His response is not courage. It is immediate scheming. That refusal to become a respectable fantasy hero gives the workplace premise its bite and makes every demand another obstacle to manipulate.
Father's Basement
Kinji's selfishness can make him exhausting company, and the satire is rarely delicate. That selfishness also keeps the setup honest. He enters an exploitative mining business and does not respond with noble endurance. He looks for leverage because returning to honest labor is unacceptable to him.
