The Dungeon of Black Company

Kinji Ninomiya has clawed his way to a self-sufficient NEET dream: plenty of money, zero obligations, and a penthouse view of everyone else trudging to work through a typhoon. Just as he’s ready to settle into a life of comfortable idleness, a mysterious portal opens beneath him and drops him into an unfamiliar world.

There, Kinji is pressed into service at a profit-obsessed mining company where workers’ safety and well-being are an afterthought. Unwilling to accept a life of corporate exploitation, he starts scheming for a fast track back to wealth—leveraging his wits, forging connections, and looking for any opening that might let him break free and reclaim the financial independence he once had.
