It's another game of Third Life and the usual rules are in place. Only three lives, they don't have memories from outside the server, they can only kill other players when they're on their red life. But this time, there's a more unique twist. This time, the goal is not to be the last one standing, but to instead be the one to defeat an unknown but powerful boss who will arrive on the server. They have twenty-four hours to prepare. They don't know what they're up against, so they can only hope the time given will be enough.
