Slow Damage

The game is set in the year 20XX and takes place in Shinkōmi (Japanese: 新神海), a fictional region in Japan that used to be once known as Tokyo Waterfront City, now run by the yakuza, the Takasato Group (Takasato Group (鷹郷組, Takasato-gumi), as the main casino resort following a massive decline in Japan, where crime is rampant and the land is exclusively controlled by the mafia as an entirely separate city. The main character, Towa, lives a careless, unhealthy lifestyle, frequently abusing alcohol and smoking cigarettes. He lives in a studio apartment above Murase Clinic and he usually gets fussed over by his friends, Taku and Rei, for his ways of living and his reckless behaviors, who tend to look after him. His sole hobby is painting and he goes by the artist name of “euphoria”. To find new models to paint, he gets in exceedingly dangerous situations, often getting himself severely hurt during sessions and rescued by his friends. His goal is to paint the "deepest and darkest human desires" by letting the models loosen their restraints and purge their very desires on Towa himself. Towa also has the ability of seeing people’s “smokes”, which are an aura people have around them that can change color and shape based on emotions, each one having a unique color for every individual and model.

The story branches off into four different routes, each focusing on one of his potential love interests, with each route having two distinct “Euphoria” and “Madness” endings. Only two routes are available at first, being Rei’s and Taku’s, with two more routes, being Madarame and Fujieda’s, unlocked later in the game on specific conditions. The first two initial routes are both preceded by an introductory, shared chapter that later develops into either one of them based on the player’s actions. Madarame’s route is unlocked after finishing the first two and making altered decisions in the first chapter, while Fujieda’s route is available when all the three are finished.
