Abandoned by his mother and having had to fend for himself, Ryuu is one of many Japanese youths that have turned to a life of petty crime in order to survive in Japanese society. Life on the streets has given him a tough exterior, but it is his kind heart and his dislike for what he has become that wins over a local beauty and helps him take his first steps towards a better life. When an overzealous and less than ethical police inspector fingers Ryuu for a crime he didn't commit, he is resigned to accept his fate. However, help emerges from an unexpected source to give him the strength to fight for his freedom: a victim of one of his past crimes.
