The year is 2052. The world is in an unprecedented era of peace, and the painkiller "Hapuna" developed by neuroscientist Dr. Skinner has made a great contribution to this. Hapuna spread all over the world as a "miracle drug" with no side effects, freeing humanity from pain. However, Skinner, the developer, suddenly disappeared, and no one knew where he was. Three years later, he reappears as a demon that will lead the world to ruin. Hapuna is a drug that causes the user to develop symptoms and die after three years, and it was a trap set. "There are 30 days left. If you can find my location by then, humanity can survive." The only way to save humanity is to use the only vaccine that Skinner has. And he says that if you want this, you have to find him. A team of five agents, "Lazarus," has been gathered from all over the world to counter Skinner's conspiracy. Can they save humanity? And what is Skinner's true purpose?
