100,000 Years to Overcome Incompetence in the Dungeon, Volume 2 - 100,000 Years to Overcome Incompetence Rikisui

The most incompetent man in the world, Kai Heinemann, obtained his gift at the age of thirteen. However, this gift ended up lowering his physical abilities by a wide margin, and in Lemures, where gifts reign supreme, he was inevitably bullied and looked down upon. Running away from home, Kai was attacked on his way to the royal capital, his desperate flight taking him straight into a dungeon.

This dungeon was arranged such that he could never leave— not at least, until he cleared the Trial of Gods. Indeed, time itself would remain at a standstill until he was done. But despite his hopeless predicament, Kai did ultimately pass his trial— though it took 100,000 years to do it.

Gaining quirky comrades on the way to the goal, he had become the strongest in the world. Now begins an exhilarating tale of the peerless boy once called the weakest of all.
