Doutei Zetsumetsu Rettou

One day, without warning, every male virgin over the age of eighteen across Japan begins dying at an alarming rate, plunging the nation into chaos. The prices for sexual services skyrocket overnight, desperate mobs of terrified virgins take to the streets, and the government is left completely unprepared to handle a crisis of this magnitude. At the center of it all is seventeen-year-old virgin Kurumi Eiri, who now faces a grim deadline: he must lose his virginity before his eighteenth birthday, or he will perish. His frantic confessions to multiple girls end in swift and crushing rejections, leaving him with little hope. Is there any way for him to escape his fate? And what will the virgins do when death is staring them directly in the face?
