In the most recent hundred years, there had not been a single grand armed melee. This was because the event was much too bloody and cruel, involving all the students of two grades in a large-scale group melee! During that time, no one would be able to control themselves — terror, rage, submission, humiliation ... there were all sorts of elements that could cause someone to lose control. A massive number of casualties had been recorded for a grand armed melee in the past — this was another important reason why the grand armed melee had faded away into obscurity for up to a hundred years.
