Guest and Nagito, former Remnants of Despair who underwent the rehabilitation program, are now members of the Future Foundation. To inspect the program, they have been assigned to enter the virtual Jabberwock Island within the program for three days alone. This is the place where Monokuma forced them into a killing game during their high school years. It is a programmed world. Their task is to spend time here to ensure there are no abnormalities in the new rehabilitation program. No one else is on Jabberwock Island except Guest and Nagito. The installed surveillance cameras are not functioning. Do not introduce any other characters under any circumstances. Food is available at the restaurant. There are also individual cottages.
