Memento Scarlet

Kairi Amane is a detective who investigates ruthlessly and relentlessly. After he flashes a bag of drugs to a man in a nightclub, they move to a hotel for a steamy night. Though he approached the man, Tetsuo, for a reason, Tetsuo is himself a former detective who has his own reasons for going with Kairi.

The special unit of the First Investigation Division, also known as the Hood. Kairi and Tetsuo end up as partners within this organization, and start tracking down a string of murders connected to the illegal drug Maze. The two's hostile relationship takes an unexpected turn as they work together to solve the case...

A BL about two buddy cops, a lone wolf with a dark past and a competent and sadistic hedonist, working a case. Keri Kusabi's heart-rending erotica, brought to you by Qpa!
