Humanity is frozen in the twilight of existence. People's lives were concentrated in evil cities. The power is in the hands of the highest, while the rest have to survive, even being inside the fortified walls. What to do? It's even worse outside. The earth has become a desert scorched by wars and diseases. And, believe me, a head bitten off by a predator is far from the worst thing that can happen there. Scavengers are genetic human garbage. It's better to be dead here than captured. Mirai was born in a fortified ancestral valley. But she had to leave as a boy. She was burned by scavengers. A descendant of an ancient family, he is brought up in a monastery as a warrior. The body grows stronger and acquires skills, but preserves the heritage of its ancestors. A warrior with the soul of a righteous man. Having found in the diary of the deceased mentor a mention of a mysterious book, he rushes in search of it. The path of the righteous sometimes lies through the vices of the city, and sometimes takes him into the desert. And she, as it turned out, keeps a lot of surprises in herself.
