My name is Lin Feng, an abandoned disciple of Shen Mingliu, with the word "traitor" engraved on my back. Human conjurers want to kill me, and monsters and ghosts want to kill me too. They all thought I was the weakest piece of trash, until I drew my sword - there was no spell consumption, no spell limit, only memories peeling off my mind like shredded paper. The first time, I forgot the master's face; the second time, I forgot the way home; the third time, the enemy knelt in a pool of blood and asked me why I helped the monster. I said, because I promised. In this Tokyo where cross-racial cooperation is prohibited, I shelter monsters, shelter human traitors, and build my own power. But the most terrifying thing is not to be the enemy of the whole world, but to wake up one day and find that you can't even remember "who you are"...
