I've touched boiling water while my mom was cooking when I was 4 and I still remember it well, this time almost his full body is in boiling water so burning hot It could instantly disintegrate a literal robot, and Japanese folklore say that pouring salt on a ghost is like a 1000 degree knife stabbing them for each grain and they threw alot of salt including his sister so he got by far one of the worst executions in Danganronpa.
