Kurosawa, a middle-aged man in his late 30s, works as a construction laborer, living a mundane and unremarkable life. Despite his age, he harbors a deep-seated resentment toward society and a desire for recognition, often fantasizing about becoming a legendary figure. Kurosawa’s life takes a turn when he begins to engage in petty acts of rebellion, such as defacing property with graffiti, as a way to assert his existence and vent his frustrations. These actions, though small, give him a fleeting sense of power and purpose.

As the story progresses, Kurosawa’s behavior escalates, and he becomes increasingly reckless.
