An anime adaptation of Naze Boku no Sekai wo Daremo Oboeteinai no ka? (Why Nobody Remembers My World?) has been officially announced.
The series follows Kai, a young man who lives in a world where the five major races are at war. In an era of human dominance, Kai fights on the frontlines. However one morning the world is irrevocably changed, the hero Sid has never existed!
Suddenly the status quo is turned around and Humanity is on the backfoot against demons, spirits, and the rest of the five races. Inheriting the hero’s sword, can Kai guide Humanity to victory without the hero; and figure out how reality was rewritten?
