so it was pretty much established that hiruma occasionally gets on mamori's nerves to the point where she had to resort to violence (the broom/mop) and i can't help but wonder if she uses other materials too depending on the availability and location?
like, if they're in class mamori could just hit him with a pen, or a notebook, or a whole ass bag if she's daring enough. if they're on the field, mamori could hurl a football or a water bottle at his general direction. she can also roll her paperwork to swat him like a fly. and if they're outside, i think mamori would chuck her shoe or sandal at him because seriously, who wouldn't? we all went through that level of frustration with someone.
what's best is that hiruma will find it entertaining.
