Too confident, Natsuko lacks to be cut out alive, but she is rescued in extremis by an unexpected guardian angel, May! For her part, Kentarô continues to believe that the union makes the strength: he therefore gathers the bulk of the survivors to seek a solution. Unfortunately, the discussion degenerates when Tsuyoshi throws himself on the young man... to force him to stab him! This sacrifice saves Kentarô, except that if he is fired from business, the number of survivors decreases from hour to hour, and Natsuko has always murdered no one...
