Resident Evil: Ars Goetia

A girl who is a fan of Resident Evil dies and meets a being who calls himself God. Offering her the chance to reincarnate in her favorite game world, she accepts. And fortunately, to survive in such a world, she gained some wishes. I wouldn't say she will be evil, but her principles and morals will change after she transforms. What for some would be bad, for her it will be normal.
