Taimanin Asagi: Battle Arena

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.

In the world where darkness roams, a man of ambition and strength has risen to destroy the equilibrium of the three ruling forces and conquer the world.

Taimanin Asagi - Battle Arena is a collectible card game for mobile and PC that gives you complete control over gorgeous ladies from across every part of the series. You take on the role of a nameless, faceless protagonist hellbent on destroying society as we know it with nothing but sheer might and will. Until now, the Taimanin have existed to satiate the lust of and kill invading demon armies with their battle-hardened bodies. Their rivals, a terrorist organization known as the Oboro Ninja Troops, want nothing more than to crush the Taimanin and let demons run amok in modern Japan.

But now, both factions have a new threat to contend with: you!
