Tokyo's criminal underworld is full of yokais, ancient magical beasts refitted under the neon lights of the city. Crime and magic writhe under ever alley, skyscraper, and port, and mercy died here a long time ago.
But now, a new player entered the fray: a man—mixed between a western gunslinger and a wandering ronin. His loyalty is in no clan and answers to no one.
He's carving a bloody path through yokai syndicates one clan at a time. A one-man army set on killing a mysterious man who is at the top of it all.

It's one man vs. all of Tokyo’s hidden monsters

and no blade, bullet, or magic is going to stop him

not even death
