Sagaki: A Tokyo Nights Novella. Tokyo Nights Novellas, #1

Jun Sagaki had it easy, well as easy as things could be for a Yakuza. He oversaw a profitable area of Tokyo for the Imaida and looked on track to become the Boss. Eventually. One day in the distant future. And then he met Hisato Shibata and his whole world got turned upside down. The position he held, the respect he garnered taken from him along with his finger. But now he's paid his penance and the Shinjuku/Kabukicho area has been handed back to him, and everything should be heading back in the right direction. Except it isn't.
And the one man he needs to rely on to stay alive just might be another undercover cop. The Tokyo Nights Novellas is a companion series to Tokyo Nights and can be read as standalones but they will contain references to events that occur in the main series.
