The Dungeon of Black Company

Kinji Ninomiya's life is all set up. He has a stable income and a great apartment, allowing him to live the rest of his life without doing any work at all. His dreams have come true - until a mysterious portal transfers him to a foreign world.

Though Kinji's plan to make easy money ultimately failed, the revenue he generated during his temporary success was noticed by his superiors. Kinji and Wanibe are transferred to a more dangerous division, to do a job they are totally unqualified for.

Kinji's next plan is to put his new allies to good use by transferring to a different group within the company with more free time. However, before he can do that, he must first endure a deadly corporate training trip.

Shia is determined to continue being a loyal corporate soldier, despite Kinji's best efforts. However, the company, and the dungeon it manages, seems to have a much more complex plan for her.

Kinji is transferred to yet another new world, this time with a more science fiction vibe. This time, however, instead of being exploited as a corporate grunt, he is worshipped as a savior.

Several high-ranking members of the Demon Lord's Army are threatened by Kinji's meteoric rise, and decide to take action against him. Meanwhile, Ranga is haunted by a secret from his past.

Kinji meets the Demon Lord and learns the truth behind this world, its problems, and how he ended up getting involved. He is given a choice - save the world, or return to his home in Japan.

During Kinji's absence, the dungeons have become more dangerous. In order to access the ruins inside, Kinji must find a way to push through the dungeons quickly, but it becomes quickly apparent that no amount of training will help.
