Suzuki is an ordinary man... until his wife is murdered. To get answers and his revenge, he abandons his law-abiding lifestyle and takes a low-level job with a front company operated by the crime gang Maiden, who are responsible for his wife's death. Before long, Suzuki finds himself caught up in a network of quirky and highly effective assassins:

The Pusher nudges people into oncoming traffic.

The Whale whispers bleak aphorisms to his victims until they take their own lives.
