In the year 2030, a nuclear war erupted, triggered by escalating environmental pollution disputes. The devastating fallout claimed countless lives, leaving the survivors to face a barren and toxic Earth. In a desperate bid to preserve humanity, these survivors launched the "Megaro Earth Project." As a final stand against the nuclear aftermath, they constructed a dome city to safeguard what remained of civilization. However, not everyone supported this lifeline. Gimmick, the enigmatic leader of the covert group known as "Black Widow," plotted to sabotage the "Megaro Earth Project." To counter his sinister plans, a specialized counter-terrorism unit, headed by the formidable lady sniper known as "EL," was assembled. EL not only fought against the Black Widow's threats but also occasionally came to the aid of the stunning Parsley, a young woman who had previously been targeted by Gimmick's operatives. In a twist of fate, Parsley, after drowning her sorrows at "Club 1991," tried to manipulate EL in her intoxicated state. Meanwhile, the tension escalated elsewhere as Natsuki endured brutal sexual torture at the hands of the Sniper Control Office, all in a ruthless quest for information.
