Doomsday Sorcerer

Six hundred years ago, the girl who was sealed in the peach blossom fan, the most precious treasure of the demon clan, broke the seal and hid in the world for the unwarranted crime of treason! When the world turns into a Shura field where the living dead are rampant, when humans who originally stood at the top of the food chain become the weakest link in the food chain, she leads the chef man with space, the boy who is as clean as a child with the ability to predict... All the way forward, looking for the final shelter!
