I never really hear anyone talk about dramatical murder, when I was younger I watched the anime without realizing there's whole ass game that goes WAAAAY more into detail (Also Dramatical murders is available on steam but if you want it uncensored you need to buy a patch for it)
The only thing I remember are the compilation of bad endings to Aoba in the OVA. It was so traumatizing that I still can't forget it to date (/TДT)/ reply
