The Writer and the Alchemist ~Gears of Judgment~

At a certain point in time in Japan, a strange phenomenon suddenly occurred in which all literary books were dyed black. This is a disaster caused by the "eroder" who was born with negative emotions in the book. The eroded literary books will gradually disappear from people's memory, and finally become as if they never existed from the beginning. Therefore, the "alchemist" with special abilities was dispatched to the library as a secret agent. In order to fight against the "eroders" who destroyed the world in the book and to protect literature, he fought with the reincarnated writers.
