The setting is modern day Tokyo; where during the day the city seems more or less peaceful, but during the night it's teeming with violence and crime; practically ruled by the Yakuza. To make matters worse: there are some among the ranks of the immense gang with special abilities who choose to abuse them for personal gain. Standard police forces are either incapable of capturing the gangsters, too afraid of them to make the attempt, or, in rare cases, some officials are bribed or personally threatened to back off. Many people aware of the danger are too fearful to go out after dark to even stop at a convenience store or vending machine, and those working at night fear for their lives and well-being. Despite all of this, there is still a select few people who feel incapable of idly watching the chaos. This is a story of one such person, a young man with special abilities of his own and a mastery of various styles of kung-fu, and the people he comes to meet and the trials he will face in the near future as he struggles to keep his true identity as a crime fighter secret.
