S Vol. 1

Welcome to Shinjuku district’s Kabukicho, Japan’s largest red light district. Here, the streets are dotted with bars, pachinko parlors and “love hotels,” which cater to all sexes and sexual orientations. It is these streets which Detective Masabi Shiiba must patrol.

A recent rise in gun crimes forces Shiiba to go undercover and work with an “S” or spy, a member of a crime organization tasked to hand over information in exchange for special favors. Shiiba’s S is a man from the influential Matsukura Group, and someone who seems to have developed a fondness for Shiiba.

But when the detective gets a mysterious call warning him about his S, seeds of doubt are planted. If he can’t trust his S, who can he trust?
