Agent "Elena," who belongs to a secret society that protects the order of the world, was assigned to a mission to improve public security in a city where it had deteriorated, alongside her lover and excellent operator, "Abel." Upon discovering that the main cause of the deteriorating security is a drug called "HH," the two of them are tasked with investigating its source and distribution routes, at which point headquarters informs them of an agent reinforcement. That agent is a frivolous-looking man named "Dion." With his flashy, superficial behavior making him seem utterly incompetent, Elena ends up having to look after him while harboring feelings of disgust and distrust. Thus begins a dangerous mission involving three people: an agent and an operator who deeply trust each other, and an incompetent subordinate agent.
