Bakumatsu. The final period of time when men fought like men... and cast their lives and ideals on a single blade.
It was the time when long peaceful Tokugawa Dynasty began to be overshadowed, triggered by the arrival of Westerners. During the upheaval, when youths were seeking for new age, there was an existence that brought turmoil and chaos. It was a supernatural Head called the Hasha no Kubi and it was said that the person who could obtain the Head, which would wake during revolution time, could rule over the whole country. On the other hand, there was another shadow existence called the Eternal Assassin. They have been destined to fight the Hasha no Kubi in order to seal. These two beings have been in eternal conflict, affecting the course of history from the shadows, influencing those who craved power.
Someone wanted it for themselves, someone wanted it for avengeance, and someone wanted it for their ideals...
The wills of men intersect over the Hasha no Kubi. They combine and move together like complicated gear wheels of an engine pushing events towards the future...
