The Mute: Ryu is a deaf-mute factory worker who is desperate to find a replacement Kidney for his ailing sister.

When he is fired from his job, he uses his severance pay, and one of his own kidneys to pay for a black market organ… but he is double crossed and left with nothing.

The Obligatory Dialogue: No dialogue, he's a proper mute.

Silent But Deadly: Ryu ambushes the organ dealers. He kills the sorry lot, and in a twist of poetic justice, removes and eats their kidneys. Actions speak louder than words indeed.
