'Shiro and Yazu Tashio are two mated half-brothers living together in the modern era. Yazu is a half demon or hanyou that was made handicapped 500 years ago by a terrible accident in a fight with his brother Shiro, a full purebred dog demon from the Shiro Inu clan. Shiro has had to give up his title as King of Demons to make a life for himself and Yazu. They live a humble life just scraping by to make ends meet. Time and change has been rough on both Yazu and Shiro as immortals never age, but the world changes around them.'
