Millions of years ago, Earth was inhabited by a race of anthropomorphic giant monsters that can grow tentacles. Following an ecological disaster, the Earth's atmosphere had started to become inappropriate for their cellular respiration and they migrated to the planet Quasar PHL-5200. Nevertheless, they did not forget about Earth and have started to send successive vanguards. Referred to as Demon Beasts by the Interplanetary Mutual Observation Agency operatives that try to stop them, the aliens are seeking to create a race of human/alien hybrids which would adapt to the Earth's atmosphere and to rule the Earth by proxy.

The story is centred on Muneto Ungyōsai and Kayō Asakura, two college students living in Tokyo. Maitreya is presented as an eschalotogical opponent to the end-days to be brought by the alien invasion.
