In the village of Droptupp, humans and demon insects have once lived among each other in peace, until the bloodsport of demonic combat entered their lives. At first this was a friendly sport of wrestling, but over time it became more and more savage to the point of it being a cruel sport where enthusiastic spectators cheered on the deaths of demon insects. Fear and misconception seeped into the minds of humans and a war began with the rise of rebellious insects.
