They announced this some time ago, but for some reason I saw the pre-registration banner on the main page. I can't find it anymore and couldn't pre-reg since it was probably a mistake. The game has the tags of RPG and Strategic Card Battle. And the best part (at least for me) is

Upcoming game: Taimanin Asagi Battle Arena-screenshot_00.jpg
The pre-reg reward is Yukikaze!

The preview:
"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."

I knew the existance of the game at DMM but never bothered on trying it or checking what's about. If someone can enlighten us with that would be appreciated.
