Upon passing a school in heaven, graduating angels are sent down to Earth, where they must learn about humans and guide them towards the correct path in order to become true angels. However, Gabriel White Tenma, the top angel in her class, becomes addicted to video games upon arriving on Earth and turns into a complete slob as a result. The story follows Gabriel, along with other angels and demons who have descended to Earth, as they attend high school.
