After the world ended in the sense where humanity is on the brink of extinction, a systematic game-like phenomenon occurred among the remaining survivors, said to be provided by "G". The system leads all survivors to "Babel"- a tower made to test individuals. It is said that those who clear the 100th floor of Babel become a god and are exempted from all punishments.  The story follows a young fellow who acquired the shittiest skill set and stat, and arguably the shittiest name... ehem... Potato. His stat started at zero while his luck stat was at -100?! Follow his journey as, despite his setback, well... can he even survive?
