Oh god, i have a theory.
Ok, in chapter five of Abandon Purpose, Mirai will finally snap and murder Raijin and Tsubame in the most horrific way possible, stabbing and shreading their bodys in a moving fan, leaving Raijins decapitated head and Tsubames hand. Her motive? Well, Tsubame tells her that she was the mastermind, and the students talents were fake. It was all to get Danganronpa back. This fills her up with fury and rage that words cant describe it. At the trial, when she is found out and the protag role goes to someone else, she straight up BREAKS Raijin and Tsubames death portraits, laughing all the while. She states that her talent as the SHSL Cartographer is meaningless, and they should see her as the SHSL Despair...
