In Danganronpa, how can a classroom trial be called if there is no corpse?
As of this moment, in both Danganronpa games and the anime adaptation of the first game, in the case the body is hidden or disposed in a way it is impossible for three witnesses to find it...


   There are no rules about how such thing would be dealt with. No such scenario happens, and no person seems to ever plan to go to such lenghts and question Monokuma about the rules for such situations, leaving us only with speculation on how this specifc situation would be dealt with.
