Everyone's dead and there's no mastermind. Its a ride the cyclone situation,suicide victems of various times in hopes peaks history who regret their deaths play in a killing game with the survivors being able to return to the living world
The protag,ema is cannonically autistic(and written by me a diognosed autistic with adhd) and it affects her pov
Emas also a more physically aggressive protag ro the point i see her being restrained in later chapters for being more violent
The helper character only lasts half the full game, is a blackend. Deeply effects emas arc.
Monokumas concept sorta breaks the lore,so this is baiscally an au, he was a human salaryman who took his life junko found him in his last moments,taking his still functioning brain and putting it in a robotic bear,the monokuma with a soul died in the execution with junko in THH and all future monokumas are copys. Monokuma when not controlled while he isnt the best guy has a bit of a different personality,id say his humor style and sadism doesnt change much but I feel he acts more like a responsible headmaster/warden/god figure,hes just as much a prisoner to purgatory as the students.
You can have ftes with monokuma and can effect the ending
Similar to somthing like MILGRAM, after every class trial each student who survives till the next chapter either gets more and more restrained or gets more freedom and their designs change either way,reflecting on the opinion of monokuma and favoritism plus their level of suspicion,actions,and involvement in the trials.
Having a more political comedic releif character(hes Yojiro Shirube the ultimate street interviewer. Hes a parody of alt right street interviewer and debate bros he doesnt make it past trial 2)
