You play as a character who lost someone dear to him and is seeking revenge. The one he's after is the leader of a clan living at the top roof of a giant fortress, protected by layers of a society that he himself has created around him. Very few have the guts to face him, so even the authorities leave him alone, or even get hired to protect him sometimes. Tetsuo is the man governing this quarter. Here, the outskirts are where he gets the money, mainly from the nightclubs, where he sells the products he bakes to feed the city. The streets outside the tower are pure chaos: gangs fighting for territory, thugs scraping by, and a police force too corrupt or powerless to restore order. Under the tower is where people live, underground, where Yakuza members keep peace and order among the addicts and gang members. Inside the tower is where the products are made, so that the higher floors can enjoy their parties and have fun while at the very top Tetsuo's men train all day and night to become the most powerful martial artists in the world, placed there to protect him from anyone who wants to tear his empire down. Here is where Tetsuo resides, watching over the world he's built, safe from anything that could get in his way. Until now, perhaps.
