The Grasshopper

In the monstrous human greenhouse of Tokyo, four almost unrelated people flit through the city like grasshoppers, each busy with their own affairs. But soon their connection will become so obvious that only death can sever it...

Suzuki is a former school teacher, consumed by a thirst for revenge for the murder of his wife. With this aim, he has infiltrated the world of the yakuza. But what can a man do who cannot even crush a bug?
Hiyoko is the assistant to the yakuza boss. This cunning beast is looking for a job for Suzuki that will determine: either he is with them, or he is a corpse.
The Cicada is a hitman without nerves or morals. He is entrusted with the dirtiest of crimes. Far above humans, this psychopath values... oysters living in his aquarium.
Kit is a top-notch specialist who forces people to commit suicide. Either he is a schizophrenic, or he can indeed see the ghosts of his victims and converse with them.

Meanwhile... the son of the yakuza boss is killed under the wheels of a car, pushed by the legendary mercenary known as the Pusher. And this Pusher, for various reasons, becomes extremely necessary to all four of them. And then they begin to inexorably move toward each other and their fate...
