Dokuro

The story is set in a dystopian near-future where Japanese society is experiencing an explosion of crime; one in which a powerful and secret religious organization, with mysterious goals, acts as an invisible hand behind the scenes.

The main character is their strongest assassin, lent to them by his fanatical mother when he was a child; nurtured into becoming a ruthless killing machine, one whose fists and feet alone can cause serious damage to his adversaries, and whose weapon of choice is a special cutting wire which grabs and scorches his victims.

He’s a man-hunter, whose childhood has been stolen by his fostering tormentors; but when the road of forgiveness is precluded to him what can be left to a man to obtain redemption?

He decides the answer is found in vengeance—and in eradicating that same fanaticism which bore him.
