Kabuto is an ordinary guy; stressed with work, hassled by his wife and disrespected by his son. No wonder he visits his doctor so often. Except 'the Doctor' is actually his handler, and Kabuto is a hired assassin. The 'prescriptions' the Doctor hands over are his unlucky targets. Because although Kabuto may seem like a small man at home, he's really good at killing people.

But Kabuto is worn out with the business of murder. He's trying to pay his way out of the Doctor's employment with a few last jobs. But the most lucrative contracts involve taking out other professional assassins and his final assignment puts both him and his family in danger.
