The story takes place after the events of OFF. You, The Puppeteer and your old puppet, The Batter are sent back once again to the old world that didn't completely die after the Batter's ending. It is still Alive. When you two are sent to what used to be Zone 0, you notice that strange things are happening within the zone, and maybe these things are also happening to the others. What will you do in this "new" world? Will the Batter eradicate it once again? It's up to you to find out.
