File:Taimanin Asagi -Battle Arena-

Description
In a near-future Japan where demons, ghouls, and dark beings roam... The ancient agreement of mutual non-intervention between humans and demons has begun to fall apart as mankind derails to the dark path. Humans and demons have colluded in criminal gangs and corporations, causing havoc and bringing forth an age of chaos.

But those who follow the path of virtue have not been left powerless. The government created an organization composed of ninjas with demon-slaying powers to fight the evil forces that plague the world. Those ninjas were known as the Taimanin.
