After the separated headings, an introduction could be seen below:
"Demons do not refer to a specific monster, but to a type of monster."
"We will not be able to deal with them with ordinary swords or firearms. These monsters, who are born with one or more spell-like abilities, are called demons."
"Their strong bodies, combined with their odd spell-like abilities, have long exceeded the understanding of the common man."
"There are also different levels amongst demons, and the weakest level is defined as a 'bullet', which means that there is still a chance to use bullets to settle the battle, while the 'blade' level is completely impossible. In fact, I would recommend any night watchmen to choose 'bombs', as long as they maintain a safe distance. As many 'bombs' as possible would be the best solution.'
