A 1:99 gender ratio means extinction, right? Are you all that stupid?
About

As a result, there are fewer than a hundred human males left in the entire world. Humans are at war with the Demon King's Army, a coalition of demons and monsters. ・Monsters Creatures fitting the general fantasy image, such as goblins and orcs. ・Demons A race closely resembling Earth's animals, far more powerful than monsters. Includes avian, reptilian, piscine, mammalian, and amphibian types.
